 — 

Pollen has exploded to eye-watering levels this spring in some parts of the country after warm weather pushed plants out of their winter slumber much earlier than normal.

In Atlanta, the pollen count sky rocketed to “extremely high” in early March and stayed high through much of April, according to the Atlanta Allergy and Asthma physicians practice. Farther north in Washington, DC, allergy sufferers have been dreading the lime-green film of pollen covering that covers windshields and porches and piles up on streets and sidewalks.

But these aren’t isolated trends. As the planet warms, researchers say allergy season is starting earlier and lasting longer. And a study from the journal Nature published last year found that pollen count is projected to increase by 200% by the end of the century if planet-warming pollution continues to rise.

Climate Central, a nonprofit focused on climate news and research, recently analyzed how warmer temperatures have affected allergy season in 203 US cities since 1970.

It found that on average, the growing season – the period between the last freeze in spring to the first freeze of fall – is lasting 16 days longer in the Southeast, 15 days longer in the Northeast and 14 days longer in the South.

In the West, growing season is 27 days longer on average, Climate Central reported. Reno, Nevada, for example, has seen a shocking increase of 99 days.

And a longer growing season means a longer allergy season.

“Because of climate change, we’re now seeing an earlier and longer growing season for plants, which of course make pollen, which is the enemy of many Americans that suffer from pollen allergies – and mold allergies as well,” Lauren Casey, a meteorologist with Climate Central, told CNN. “Pollen can also trigger an asthma attack, which of course is much more serious for people that suffer from asthma.”

When plants reproduce, typically during the spring, many release tiny pollen grains that are carried by wind. The pollen grains are small enough to be inhaled, and some people’s immune systems react very poorly to the miniscule particles.

More than 24 million people in the US have pollen-induced respiratory allergies like hay fever, according to the Centers for Disease Control and Prevention. The center’s data shows that more than one in four adults suffered from seasonal allergies in 2021.

Growing season has lengthened by 34 days in Atlanta, according to a Climate Central analysis.

Growing season has lengthened by 20 days in Washington, DC, according to a Climate Central analysis.

A longer and earlier start to pollen season could trigger a public health emergency, researchers say. As temperatures get warmer in the South and drought plagues the Southwest, pollen from plants like ragweed or poaceae – a plant that typically grows in grasslands or salt-marshes – is projected to be higher across those regions than in the North.

Wind-driven pollen, which plays an important role in plant fertilization, is closely tied to temperature and precipitation changes. So, as spring seasons get warmer earlier due to climate change, plants could pollinate much earlier and for a longer period of time than they currently do.

Plant pollen isn’t the only trigger of seasonal allergies. Mold, a type of fungi that reproduces with tiny airborne spores, can also be allergenic for some people and can exacerbate seasonal allergies, according to the report.

While outdoor mold is not as well-studied as pollen, according to the report, one thing is clear: Warmer and wetter weather – conditions that many locations are seeing more of amid the climate crisis – is favorable for mold development.

“With climate change, we’re seeing increases in warming in all seasons, but particularly the fastest warming season for most locations across the US is the winter season,” Casey said. “So now we’re dealing with mold at a time of year that we typically wouldn’t.”

Casey also pointed out that the climate crisis is making extreme precipitation more likely, which provides that crucial dampness for mold to grow. The report highlights the link between allergens and thunderstorms, which researchers say spread pollen and mold spores through the air more efficiently.

“The problem with pollen grains is that when they get wet, they rupture, and they break into tinier bits called sub-pollen particles,” Casey said. “Those tinier bits are more easily dispersed by the wind when they dry out, and they have an easier time getting into your nasal passages.”

Oak trees are pumping out pollen in the Southeast, contributing to extremely high levels early in the season.

Dr. Mitchell Grayson, chair of the Asthma and Allergy Foundation of America’s Medical Scientific Council and chief of the division of allergy and immunology at Nationwide Children’s Hospital, said he has seen pollen allergies arrive earlier than usual.

“In general, we may be seeing people a little earlier in the spring with symptoms – so mid-February from what might have been early March in the past – but there is significant year-to-year variability in this,” he told CNN. “I haven’t seen worse symptoms, but I’m in a hospital that provides specialist care, and we do see people with all ranges of severity.”

The treatment of allergies won’t change even as the season gets longer, Grayson said. But it’s important to be aware of what you’re allergic to and know where these triggers are in the environment.

Experts recommend:

  • Staying indoors, especially early in the morning or late in the afternoon, when most plants release pollen.
  • Wear masks outdoors when possible to mitigate the effects, Amiji said.
  • Keeping windows closed in your home and car to minimize your exposure to pollen particles.
  • Changing air filters more frequently for your A/C and heating systems in your home and car, according to the manufacturer’s instructions.
  • Preparing early by stocking up on anti-allergy medications. If you use a steroid nasal spray, Grayson said it’s important to start using it one to two weeks before your allergy season and to continue through the full season.

Casey, the meteorologist, also noted that allergy season could be a financial burden on low-income families, especially those whose members have asthma, due to the “billions of dollars spent a year on the medical costs of asthma and allergies.”

She said awareness is key, especially as the world pumps more carbon pollution into the atmosphere, which could worsen allergy seasons.

“You know your own body and are aware of what a typical year is going to look like for you, especially if you’re an allergy sufferer,” she said. “But that whole paradigm is changing with this increase in the growing season, so having awareness that you may be suffering now and going forward in times of the year when you typically wouldn’t, so be prepared for that in your daily life.”

A quarter of Americans live with polluted air, with people of color and those in Western states disproportionately affected, report says | CNN



CNN
 — 

About 1 in 4 people in the United States – more than 119 million residents – live with air pollution that can hurt their health and shorten their lives, according to a new report from the American Lung Association. People of color are disproportionately affected, as are residents of Western cities.

Since President Richard Nixon signed the Clean Air Act in 1970, emissions of outdoor air pollutants have fallen 78%, according to the US Environmental Protection Agency. But Wednesday’s 2023 State of the Air report, which focuses on ozone and particle pollution, shows that millions put their health on the line every time they step outside.

To capture pollution levels at the county level, researchers analyzed data collected by the EPA’s Air Quality System, a repository of ambient air quality data from more than 10,000 monitors. They characterized the hourly average ozone concentration and the 24-hour average particle pollution concentration for 2019-21 at each monitoring site and factored in year-round pollution information from the EPA.

There were significant improvements in some areas. Generally, 17.6 million fewer people were breathing unhealthy air than in last year’s report, due largely to falling levels of ozone in some regions.

Ozone pollution is the main ingredient in smog. It comes from cars, power plants and refineries. Exposure to ozone can immediately exacerbate asthma symptoms, and people with long-term exposure to higher levels face a significantly higher risk of death from respiratory diseases than those who live with cleaner air.

Around 25% more counties got an A grade in the report for lower levels of ozone pollution. Some of that improvement can be attributed to the Clean Air Act, according to Katherine Pruitt, author of the report and the American Lung Association’s national senior director for policy.

Emission controls have helped, she said, as has the country’s continuing move away from its reliance on coal for its energy needs. Even something simple as the increase in the number of people who work from home has played a role.

“The Biden administration has set themselves a good, strong to do list of things that will help with environmental justice and climate protection,” Pruitt said. “They’re moving kind of slow, though. So we’d like them to pick up the pace.”

Despite the progress, not everyone was lucky enough to live in a county with good ozone levels. More than 100 million people live in counties that get an F for ozone smog, the report says.

Western and Southwestern cities are the most ozone-polluted, with 10 of the 25 most-polluted cities in California. New York, Chicago and Hartford, Connecticut, were the only three on that list east of the Mississippi River.

The five metropolitan areas with the worst ozone pollution are Los Angeles-Long Beach, California; Visalia, California; Bakersfield, California; Fresno-Madera-Hanford, California; and Phoenix-Mesa, Arizona.

Particle pollution, the other form of pollution tracked in the report, still seems to be a significant issue for the US.

Often hard to see, particle pollution is a mix of solid and liquid droplets that may come in the form of dirt, dust, soot or smoke. Coal- and natural gas-fired power plants create it, as do cars, agriculture, unpaved roads, construction sites and wildfires.

Particle pollution is so tiny – 1/20th of a width of a human hair – that it can travel past your body’s usual defenses.

Instead of being carried out when you exhale, it can get stuck in your lungs or go into your bloodstream. The particles cause irritation and inflammation and may lead to respiratory problems. Exposure can cause cancer, stroke or heart attack; it could also aggravate asthma, and it has even been associated with a higher risk of depression and anxiety, studies show.

The new report says the number of people living in counties with failing grades for daily spikes of particle pollution was the highest it has been in a decade. Nearly 64 million live with these kind of unhealthy spikes in counties that get failing grades.

One driver of the high amounts of particle pollution are the wildfires that have consumed hundreds of thousands of acres. In 2021 alone, there were 14,407 fires, many in the West, according to the National Interagency Fire Center. There used to be a wildfire season, experts say, but now they happen year-round.

Those fires are why the regions with the highest concentrations of air pollution are largely in the West.

When the American Lung Association started producing its report in 2004, 106 counties in 30 states got failing grades for daily spikes in particle pollution. Fewer than half were in eight states west of the Rocky Mountains. Today, 111 counties in 19 states got Fs for spikes in particle pollution, and all but eight counties are in the West, the report says.

Urban centers in the Rust Belt and the industrialized East had gotten the most failing grades in the early 2000s, but many have cleaned up and now get passing grades.

Bakersfield, California, displaced Fresno as the metropolitan area with the worst short-term particle pollution, but Fresno did not suddenly develop cleaner air. That city still had the most-polluted label for year-round particle pollution, tied with Visalia, in the agricultural San Joaquin Valley.

Los Angeles is still the city with the worst ozone pollution, according to the report, as it has been for all but one of the years included in the report.

California has some of the more progressive environmental legislation in the country, but the climate crisis has not been kind to the state, said Tarik Benmarhnia, an air pollution and wildfire researcher at the University of California, San Diego, who did not work on the new report.

“All these cities like Bakersfield and Visalia are in a valley near the forests that are seeing big fires. There’s also intense agricultural and industrial work there, so they unfortunately have all the worst conditions for air pollution,” Benmarhnia said.

There are some newcomers to the list of the 25 areas with the most particle pollution, including Denver and Fargo, North Dakota. Reno, Nevada; Yakima and Spokane, Washington; and Boise, Idaho; all made the worst list this year.

San Luis Obispo, California; Portland, Oregon; and Seattle and Bellingham, Washington; all moved off the list of worst 25 cities.

Residents in the cities ranked worst for particle pollution are living with more of it, the report says. In the top 25 cities with the worst air, the average number of days residents were exposed to high levels of fine particle pollution increased to a weighted average of 18.3, up from 16.5 in last year’s report.

East of the Mississippi, Pittsburgh and Lancaster, Pennsylvania, were the two worst metropolitan areas in the country, posting more days high in fine particle pollution in this year’s report.

Not everyone experiences pollution the same way in the US. Regardless of the region, communities of color bear the brunt of the problem.

Specifically, although people of color make up 41% of the overall US population, they are 54% of the nearly 120 million people living in counties with at least one failing grade for unhealthy air. And in the counties with the worst air quality, 72% of the 18 million residents are people of color, the report said.

Other research has also shown this trend. On maps that lay out areas with high levels of air pollution and where communities were redlined – areas where Black people were forced to live – they line up perfectly, Pruitt said.

“Then, the other aspect is, when you have a community of color that is a voluntary community, people aren’t forced to live there, those are communities that tend to have less of a voice, so decision makers place polluting sources in those communities because there’s not as much howling by people with power when they do. So those communities get the highways; they get the landfills; they get the fence lines,” she said.

There’s a myth that only poor communities live with disproportionate pollution levels, says Chris Tessum, a professor in the Civil and Environmental Engineering Department of the University of Illinois. Tessum, who was not involved in the new report, says race really is the determining factor.

“The thinking is that people with more money will buy better property, which has lower air pollution and that’s just the way of the world or whatever, but that’s just kind of emphatically not, not true,” he said.

Communities need to play a key role in making decisions to help clean air, Tessum said.

“People that have the power will use that power to benefit themselves and not the people that have been historically overburdened,” he said.

The new report says government and residents can make a difference. One suggestion is to leverage Inflation Reduction Act funding to help reduce emissions at ports and to invest in zero-emission heavy-duty vehicles and in infrastructure that would improve air quality monitoring.

States can also use the Clean Air Act authority to adopt the California zero-emissions standards for cars and trucks, the report says.

At the federal level, agencies must finalize stronger limits on air pollution to truly protect public health and advance environmental justice, the report says, including standards to move the country toward zero-emissions vehicles. The EPA also has to set stronger national standards for particle pollution and ozone, the researchers say.

Pruitt said she knows firsthand how better policies can work. She said growing up before the Clean Air Act, pollution was so high that she could see it every time she stepped outside. Today, the pollution is not nearly as visible.

“I’m in my mid-60s, and of course, air pollution was very tangible when I was young, but these days, thank goodness it isn’t. Most people don’t see it,” she said. Unless a person has a lung condition, they may not even feel it.

But just because you can’t see it or feel it doesn’t mean it’s not there. Pruitt encourages people to remember that no level of pollution is safe. The World Health Organization estimates that the combined effects of ambient air pollution and household air pollution are associated with 6.7 million premature deaths annually.

“People don’t really recognize that what they’re breathing is impacting their health,” Pruitt said.

EPA proposes new regulations on toxic gas used to sterilize spices and medical equipment | CNN



CNN
 — 

The US Environmental Protection Agency on Tuesday proposed a set of new restrictions on facilities that use the cancer-causing chemical ethylene oxide, a colorless, odorless gas that is used to sterilize medical devices and spices.

The agency said the new rules, which have not been finalized, would help to reduce ethylene oxide gas that these facilities release by 80%, bringing emissions below a Clean Air Act standard for elevated cancer risk.

Communities exposed to ethylene oxide gas have been pushing the EPA to put tighter controls on plants that use ethylene oxide gas.

In 2018, an EPA report found that dozens of communities across the nation faced elevated cancer risks because of trace of amounts of ethylene oxide released into air as part of the sterilization process.

The EPA issued the report on the new risks without issuing a news release, as it had done for the same report in years past. Some affected communities learned of the risk through a health assessment conducted by the Agency for Toxic Substances and Disease Registry, a division of the US Centers for Disease Control and Prevention, and media reports. A report from the EPA’s Office of the Inspector General found that some communities weren’t alerted to their risk by EPA at all.

The elevated risk became apparent after a two-decade long review of the toxicity of ethylene oxide by scientists in EPA’s Integrated Risk Information System (IRIS) program.

While the EPA acknowledged that ethylene oxide was more dangerous that had been previously understood, it continued to use an older set of rules to regulate facilities that released ethylene oxide as well as companies that manufacture it.

The proposed rules aim to better align regulations on the producers and users of ethylene oxide with the cancer risk posed by the chemical. They follow a set of proposed rules issued by EPA last week that would put new controls on facilities that manufacture ethylene oxide.

Taken together, the two sets of rules would remove 77 tons of ethylene oxide emissions a year, an 84% reduction compared with 2020 levels, EPA Deputy Administrator Janet McCabe said in a call with reporters on Tuesday.

Environmental watchdog groups applauded the proposed restrictions, but noted that they don’t go far enough to protect vulnerable communities, where residents are often low-income and disproportionately people of color.

“These regulations are long overdue, by almost a decade. I’m relieved and pleased that the EPA has finally issued proposed standards that are based on their own scientists’ recommendations on an updated, higher cancer risk value. If enacted, these updated regulations would reduce emissions in fenceline communities,” said Darya Minovi, a senior researcher scientist at the Union of Concerned Scientists.

“When the EPA issues the final rule, they should throw the net wider. The standard should cover a larger range of facilities to include off-site warehouses that often store recently sterilized equipment that continue to release ethylene oxide, but aren’t regulated for their air emissions.”

Minovi also said the EPA should require fenceline monitors – devices that constantly read the air outside of facilities to make sure that toxic gas isn’t drifting into neighborhoods.

Jaime Rukstales, a member of the Illinois grassroots advocacy group Stop EtO in Lake County – one of the communities impacted by ethylene oxide pollution – says the EPA needs to impose tougher restrictions on “all types of facilities that impact the health of our communities … including sterilizers, manufacturers and warehouses near our homes, schools and businesses.”

Some off-site warehouses used to store newly sterilized products have registered high levels of ethylene oxide due to off-gassing of the products.

Meanwhile, chemical manufacturers sued the EPA in February over its updated hazard assessment for ethylene oxide. The industry wants the agency to use a less protective standard developed by the Texas Commission on Environmental Quality.

AdvaMed, a group that lobbies for the interests of medical device manufacturers, warned that more regulations could pose problems for patients.

“If new EPA regulations force sterilization facilities to close, patients could face treatment delays as sterile technology supplies, such as pacemakers and surgical equipment, fall short,” Scott Whitaker, president and CEO of AdvaMed, said in a comment posted on the group’s website.

The EPA said some commercial sterilizers have already made the planned changes.

“Many sterilization and health care facilities are already taking the steps outlined in the proposal and have seen emissions drop significantly,” McCabe said.

Most facilities have taken action to control ethylene oxide blown out of sterilization chambers through exhaust vents known as “back vents” but only 25% to 33% of sterilizers are controlling so-called fugitive emissions, ethylene oxide that escapes or leaks into room air, said Jonathan Witt, an environmental engineer and technical lead on EPA’s review of the National Emissions Standards for Hazardous Air Pollutants.

“So we think it’s a good sizable chunk of the industry, but still a little ways to go,” Witt said on a call with reporters.

If the rules go into effect, sterilizers would have 18 months to make the changes, which the EPA said is an accelerated time frame under the Clean Air Act.

AdvaMed’s Whitaker says that’s not enough time.

“It could take many months for abatement equipment to arrive. Supply chains and manufacturing are still recovering from the pandemic,” he noted in the statement.

In issuing the proposed rules, the EPA said it aimed to strike a balance between lowing cancer risks for impacted communities and workers who use ethylene oxide while preserving “critical sterilization capabilities.”

The proposed rules would apply to 86 commercial sterilization facilities in the United States that use ethylene oxide gas to fumigate spices and medical devices.

The EPA says 20 billion medical devices – mostly single-use, disposable items used in health care such as catheters, gloves and surgical gowns – are sterilized using ethylene oxide.

The US Food and Drug Administration is actively exploring alternatives to the use of the gas, the EPA said on Tuesday, but some devices still can’t be sterilized any other way.

In proposing the new rules, EPA said its new analysis found that exposure to ethylene oxide, or EtO, on the job significantly increased cancer risks for workers in sterilization facilities and those who apply ethylene oxide in health care facilities.

“Now, a new EPA analysis shows that there may also be significant risks to workers who handle [ethylene oxide] and people who live, work or go to school near places where EtO is used in sterilization. And failing to take action to address these risks is simply unacceptable,” EPA Administrator Janet McCabe said on a call with reporters.

The additional lifetime cancer risk for a worker exposed to ethylene oxide for eight hours a day, 240 days a year for 35 years was between 1 in 10 and 1 in 36 for workers in sterilization facilities; and between 1 in 12 and 1 in 25 for workers exposed to ethylene oxide in health care facilities.

To help lower those risks, the proposed rules require greater use of personal protective equipment for workers and new controls to decrease the amount of ethylene oxide in indoor air.

Whitaker from AdvaMed, the medical device industry group, said the cancer risk for employees exposed to ethylene oxide on the job is overstated and disregards “the strong employee protections already in practice.”

Companies will also be required to use new real-time monitoring methods to confirm that these pollution controls are working inside facilities. These controls can measure ethylene oxide in indoor air down to 10 parts per billion. If ethylene oxide levels climb above this threshold, everyone in the workplace would be required to wear protective equipment.

They will also lower the amount of ethylene oxide that can be used for each sterilization cycle. The EPA is proposing to limit the application rate for ethylene oxide to no more than 500 milligrams per liter of air.

The rules would eliminate some niche uses of ethylene oxide where alternatives exist, including its use in museums, archival settings, beekeeping, some cosmetics, and in musical instruments.

The EPA will take public comment on the new rules for 60 days. The agency will also host a virtual public webinar on May 1 to discuss its proposed rules and new risk assessment.

Fossilized eggs crack open the mysteries of the past | CNN

Sign up for CNN’s Wonder Theory science newsletter. Explore the universe with news on fascinating discoveries, scientific advancements and more.



CNN
 — 

Eggs have been laid on land by birds, reptiles, dinosaurs and a few oddball mammals for more than 200 million years.

And humans have been using some of these eggs as a nutritious source of food, and their shells as bowls, bottles and jewelry for most of our history on the planet.

Though they’ve often been overshadowed by skeletons and bones, fossilized eggshells are a fascinating source of information, illuminating the behavior and diet of ancient creatures, detailing changes in climate and revealing how our prehistoric relatives lived and communicated.

This Easter, here are six surprising things eggs have revealed about the past.

Did dinosaur blood run cold, like a lizard, or warm, like a bird? It’s a topic that’s long divided paleontologists.

An analysis of fossilized dinosaur egg shells suggests it’s the latter. By looking at the order of oxygen and carbon atoms in the fossilized egg shells, researchers were able to calculate a dinosaur mom’s internal body temperature. It’s a process called “clumped isotope paleothermometry.”

“Eggs, because they are formed inside dinosaurs, act like ancient thermometers,” said Pincelli Hull, an assistant professor at Yale University’s department of geology and geophysics, and a coauthor of the study, which published in 2020.

Hull and her colleagues found that the samples they tested suggested dinosaurs’ body temperatures were warmer than their surroundings would have been.

The research indicates that unlike reptiles, which rely on heat from the environment, dinosaurs were capable of internally generating heat – more like birds.

A study of fossilized eggshells revealed humans may have been hatching and raising cassowaries for more than 18,000 years.

You might think that chickens—or even ducks or turkeys—were the earliest birds to be domesticated by humans.

However, eggshell fragments found at two prehistoric sites in Papua New Guinea suggest that humans may have been raising cassowaries—often described as the world’s most dangerous birds because of a daggerlike claw they have on each foot—as early as 18,000 years ago.

Territorial, aggressive and often compared to a dinosaur in looks, the bird is a surprising candidate for domestication. But a study of more than 1,000 fossilized Papua New Guinea eggshell fragments has suggested the birds were deliberately hatched.

To reach their conclusions, the researchers first studied the eggshells of living birds, including turkeys, emus and ostriches. The insides of the eggshells change as the developing chicks get calcium from the eggshell. Using high-resolution 3D images and inspecting the inside of the eggs, the researchers were able to build a model of what the eggs looked like during different stages of incubation.

The scientists tested their model on modern emu and ostrich eggs before applying it to the fossilized eggshell fragments found in New Guinea. The team found that most of the eggshells found at the sites were all near maturity—suggesting they were hatched, not eaten.

The first oviraptor fossil—from a family of dinosaurs with parrotlike beaks—was discovered in Mongolia in the 1920s, lying near a nest of eggs thought to belong to a rival. Paleontologists at the time assumed that the animal had died while attempting to plunder the nest and named the creature “egg thief.”

It wasn’t until the 1990s that its reputation was restored when another discovery revealed that the eggs were its own. Subsequent finds, including an oviraptosaur hunched over 24 eggs made public last year, have revealed that this particular type of dinosaur was a doting parent.

At least seven of the 24 eggs preserved the bones of partial embryos found inside; it was the first time a fossil had preserved this level of detail. These embryos were at a late stage of development, and the close proximity of the parent confirmed that this dinosaur really did incubate its nest like its modern bird cousins.

The neat layout of oviraptor nests also suggested that they were brooders that sat upon eggs to hatch them—even giant oviraptors that weighed 1,500 kilograms (3,307 pounds) and laid half-meter long eggs, said Darla Zelenitsky, a dinosaur egg expert and associate professor in the department of geoscience at the University of Calgary in Canada.

“These fossils also show very precisely arranged eggs, stacked in rings, probably optimized for sitting on the eggs,” she explained.

The 2-meter-wide (6.6-foot-wide) nests of giant oviraptors were a slightly modified shape to stop them from being crushed, she added.

Dinosaurs eggs—including one with a perfectly preserved baby dinosaur curled up inside—increasingly show that birds inherited many characteristics from dinosaurs. Not all dinosaurs, however, were caring parents.

Pores on the surface of eggs allow the diffusion of water, oxygen and carbon dioxide, and the orientation, density and number of pores on the eggs of living animals can reveal whether they are laid in open nests or underground. Applying this knowledge to fossilized dinosaur eggs has shed light on their nesting behavior.

Analysis suggests that many dinosaurs, including hulking plant-eating sauropods, laid their eggs underground in burrows, more like reptiles.

A string of modern ostrich eggshell beads from eastern Africa is shown.

Ostrich eggshells are found in archaeological dig sites throughout Africa. Early humans used the large eggs as water bottles and, for tens of thousands of years, ancient humans took the remains and fashioned them into decorative beads that are still made today.

These beads have been found all over Africa—including in areas where ostriches never lived – sparking the question of how they got there.

The answer is hidden in the eggs’ geochemistry. Researchers looked at the signatures of different isotopes or variants of the element strontium in the beads—these vary depending on where the ostriches would have fed before laying the eggs.

Older rock formations including granite are found to have more strontium than younger rocks like basalt, and this is reflected in the vegetation that grows around them.

The geochemistry of the beads showed they traveled long distances. They were traded or exchanged in what was described as an early social network.

Eggs are a big part of our diet today – something that was also true in the Stone Age.

In fact, ancient Australians’ appetite for the eggs laid by the 2-meter-tall (6-foot-tall) Genyornis could have been one significant reason why the large, flightless birds went extinct 47,000 years ago.

Burn patterns on eggshell fragments of the giant bird found at around 200 sites across Australia, were created by humans discarding eggshell in and around makeshift fires, presumably made to cook the eggs.

Chemical signatures of nitrogen and carbon isotopes in fossilized egg shells can also track vegetation changes, gleaning information about past changes in climate, which can reveal ecological shifts that could impact the survival of these species over time.

A study of emu eggshells found across Australia over a 100,000-year time period do not show a massive shift in climate that researchers believe could have led to the extinction of Genyornis.

This suggested that the extinction of these giant birds was caused by humans, not ecological changes, the study said.

Fossilized penguin, ostrich and emu eggshells have revealed what the climate was like in the ancient Antarctic, South Africa and Australia. More recent egg collections are revealing how the current climate crisis is changing the natural world today.

By comparing birds’ eggs collected during the Victorian era and modern eggs held by the Field Museum and other institutions, researchers found that several bird species in the Chicago area nest and lay eggs almost a full month earlier now than they did a century ago.

Of the 72 species documented in the data, a third have been nesting earlier and earlier, the team found. Birds that changed their nesting habits laid eggs around 25 days sooner, on average.

Similar patterns are seen in insects, which many birds eat, and plants, suggesting that climate change is already changing ecosystems, the authors of the study said.

How to reduce PFAS in your drinking water, according to experts | CNN

Editor’s Note: Get inspired by a weekly roundup on living well, made simple. Sign up for CNN’s Life, But Better newsletter for information and tools designed to improve your well-being.



CNN
 — 

In the next three years, drinking water in the United States may be a bit safer from potentially toxic chemicals that have been detected in the blood of 98% of Americans.

Perfluoroalkyl and polyfluoroalkyl substances or PFAS are a family of thousands of man-made chemicals that do not break down easily in the environment. A number of PFAS have been linked to serious health problems, including cancer, fertility issues, high cholesterol, hormone disruption, liver damage, obesity and thyroid disease.

The US Environmental Protection Agency proposed on Tuesday stringent new limits on levels of six PFAS chemicals in public water systems. Under the proposed rule, public systems that provide water to at least 15 service connections or 25 people will have three years to implement testing procedures, begin notifying the public about PFAS levels, and reduce levels if above the new standard, the EPA said.

Two of the most well-studied and potentially toxic chemicals, PFOA and PFOS, cannot exceed 4 parts per trillion in drinking water, compared with a previous health advisory of 70 parts per trillion, the EPA said.

Another four chemicals — PFNA, PFHxS, PFBS and GenX — will be subject to a hazard index calculation to determine whether the levels of these PFAS pose a potential risk. The calculation is “a tool the EPA uses to address the cumulative risks from all four of those chemicals,” said Melanie Benesh, vice president of government affairs for the Environmental Working Group, a consumer organization that monitors exposure to PFAS and other chemicals.

“The EPA action is a really important and historic step forward,” Benesh said. “While the proposed regulations only address a few PFAS, they are important marker chemicals. I think requiring water systems to test and treat for these six will actually do a lot to address other PFAS that are in the water as well.”

For people who are concerned about PFAS exposure, three years or so is a long time. What can consumers do now to limit the levels of PFAS in their drinking water?

First, look up levels of PFAS in your local public water system, suggested David Andrews, a senior scientist at the Environmental Working Group. The advocacy nonprofit has created a national tap water database searchable by zip code that lists PFAS and other concerning chemicals, as well as a national map that illustrates where PFAS has been detected in the US.

However, not all water utilities currently test for pollutants, and many rural residents rely on wells for water. Anyone who wants to personally test their water can purchase a test online or from a certified lab, Andrews said.

“The most important thing is to ensure the testing method can detect down to at least four parts per trillion or lower of PFAS,” he said. “There are a large number of labs across the country certified to test to that level, so there are a lot of options available.”

If levels are concerning, consumers can purchase a water filter for their tap. NSF, formerly the National Sanitation Foundation, has a list of recommended filters.

“The water filters that are most effective for PFAS are reverse osmosis filters, which are more expensive, about in the $200 range,” Andrews said. Reverse osmosis filters can remove a wide range of contaminants, including dissolved solids, by forcing water through various filters.

“Granular activated carbon filters are more common and less expensive but not quite as effective or consistent for PFAS,” he said, “although they too can remove a large number of other contaminants.”

Reverse osmosis systems use both carbon-based filters and reverse osmosis membranes, Andrews explained. Water passes through the carbon filter before entering the membrane.

“The important part is that you have to keep changing those filters,” he said. “If you don’t change that filter, and it becomes saturated, the levels of PFAS in the filtered water can actually be above the levels in the tap water.”

Carbon filters are typically replaced every six months, “while the reverse osmosis filter is replaced on a five-year time frame,” he added. “The cost is relatively comparable over their lifetime.”

Another positive: Many of the filters that work for PFAS also filter other contaminants in water, Andrews said.

Drinking water is not the only way PFAS enters the bloodstream. Thousands of varieties of PFAS are used in many of the products we purchase, including nonstick cookware, infection-resistant surgical gowns and drapes, mobile phones, semiconductors, commercial aircraft, and low-emissions vehicles.

The chemicals are also used to make carpeting, clothing, furniture, and food packaging resistant to stains, water and grease damage. Once treated, the report said, textiles emit PFAS over the course of their lifetimes, escaping into the air and groundwater in homes and communities.

Made from a chain of linked carbon and fluorine atoms that do not readily degrade in the environment, PFAS are known as “forever chemicals.” Due to their long half life in the human body, it can take some PFAS years to completely leave the body, according to a 2022 report by the prestigious National Academies of Sciences, Engineering, and Medicine.

“Some of these chemicals have half-lives in the range of five years,” National Academies committee member Jane Hoppin, an environmental epidemiologist and director of the Center for Human Health and the Environment at North Carolina State University in Raleigh, told CNN previously.

“Let’s say you have 10 nanograms of PFAS in your body right now. Even with no additional exposure, five years from now you would still have 5 nanograms.

“Five years later, you would have 2.5 and then five years after that, you’d have one 1.25 nanograms,” she continued. “It would be about 25 years before all the PFAS leave your body.”

The 2022 National Academies report set “nanogram” levels of concern and encouraged clinicians to conduct blood tests on patients who are worried about exposure or who are at high risk. (A nanogram is equivalent to one-billionth of a gram.)

People in “vulnerable life stages” — such as during fetal development in pregnancy, early childhood and old age — are at high risk, the report said. So are firefighters, workers in fluorochemical manufacturing plants, and those who live near commercial airports, military bases, landfills, incinerators, wastewater treatment plants and farms where contaminated sewage sludge is used.

The PFAS-REACH (Research, Education, and Action for Community Health) project, funded by the National Institute of Environmental Health Sciences, gives the following advice on how to avoid PFAS at home and in products:

  • Stay away from stain-resistant carpets and upholstery, and don’t use waterproofing sprays.
  • Look for the ingredient polytetrafluoroethylene, or PTFE, or other “fluoro” ingredients on product labels.
  • Avoid nonstick cookware. Instead use cast-iron, stainless steel, glass or enamel products.
  • Boycott takeout containers and other food packaging. Instead cook at home and eat more fresh foods.
  • Don’t eat microwave popcorn or greasy foods wrapped in paper.
  • Choose uncoated nylon or silk dental floss or one that is coated in natural wax.

Saving water can help us deal with the climate crisis. Here’s how to reduce your use | CNN

Editor’s Note: Sign up for CNN’s Life, But Greener newsletter. Our limited newsletter series guides you on how to minimize your personal role in the climate crisis — and reduce your eco-anxiety.



CNN
 — 

The reliability of our faucets providing water every time we turn them on can make water seem like a magical, never-ending resource.

But abusing the availability of this finite resource can contribute to water scarcity and harm our capacity to deal with the impact of the climate crisis.

“Four billion people today already live in places that are affected by water scarcity at least part of the year,” said Rick Hogeboom, executive director of the Water Footprint Network, an international knowledge center based in the Netherlands. “Climate change will have a worsening influence on the demand-supply balance,” he said.

“If all people were to conserve water in some way, that would help ease some of the immediate impacts seen from the climate crisis,” said Shanika Whitehurst, associate director of sustainability for Consumer Reports’ research and testing. Consumer Reports is a nonprofit that helps consumers evaluate goods and services.

“Unfortunately, there has been a great toll taken on our surface and groundwater sources, so conservation efforts would more than likely have to be employed long term for there to be a more substantial effect.”

Yes, businesses and governments should play a part in water conservation by, respectively, producing goods “water efficiently” and allocating water in a sustainable, equitable way, Hogeboom said.

But “addressing the multifaceted water crises is a shared responsibility. No one actor can solve it, nor is there a silver bullet,” he added. “We need all actors to play their part.”

Contrary to what you might think, the water used directly in and around the home makes up a minor portion of the total water footprint of a consumer, Hogeboom said.

“The bulk — typically at least 95% — is indirect water use, water use that is hidden in the products we buy, the clothes we wear and the food we eat,” Hogeboom said. “Cotton, for instance, is a very thirsty crop.”

Of the 300-plus gallons of water the average American family uses every day at home, however, roughly 70% of this use occurs indoors, according to the US Environmental Protection Agency — making the home another important place to start cutting your use.

Here are some ways to reduce your water footprint as you move from room to room and outdoors.

Since the kitchen involves dishwashing, cooking and one of the biggest water guzzlers — your diet — it’s a good place to start.

An old kitchen faucet can release 1 to 3 gallons of water per minute when running at full blast, according to Consumer Reports. Instead of rinsing dishes before putting them in the dishwasher, scrape food into your trash or compost bin. Make sure your dishwasher is fully loaded so you only do as many wash cycles as necessary and make the most use of the water.

With some activities you can save water by not only using less but also upgrading the appliances that deliver the water. Dishwashers certified by Energy Star, the government-backed symbol for energy efficiency, are about 15% more water-efficient than standard models, according to Consumer Reports.

If you do wash dishes by hand, plug up the sink or use a wash basin so you can use a limited amount of water instead of letting the tap run.

If you plan on eating frozen foods, thaw them in the fridge overnight instead of running water over them. For drinking, keep a pitcher of water in the fridge instead of running the faucet until the water’s cool — and if you need to do that to get hot water, collect the cold water and use it to water plants.

Cook foods in as little water as possible, which can also retain flavor, according to the University of Toronto Scarborough’s department of physical and environmental sciences.

When it comes to saving water via what you eat, generally animal products are more water-intensive than plant-based alternatives, Hogeboom said.

“Go vegetarian or even better vegan,” he added. “If you insist on meat, replace red meat by pig or chicken, which has a lower water footprint than beef.”

It takes more than 1,800 gallons of water to produce 1 pound of beef, Consumer Reports’ Whitehurst said.

The bathroom is the largest consumer of indoor water, as the toilet alone can use 27% of household water, according to the EPA. You can cut use here by following this adage: “If it’s yellow, let it mellow. If it’s brown, flush it down.”

“Limiting the amount of toilet flushes — as long as it is urine — is not problematic for hygiene,” Whitehurst said. “However, you do have to watch the amount of toilet paper to avoid clogging your pipes. If there is solid waste or feces, then flush the toilet immediately to avoid unsanitary conditions.”

Older toilets use between 3.5 and 7 gallons of water per flush, but WaterSense-labeled toilets use up to 60% less. WaterSense is a partnership program sponsored by the EPA.

“There’s probably more to gain by having dual flush systems so you don’t waste gallons for small flushes,” Hogeboom said.

By turning off the sink tap when you brush your teeth, shave or wash your face, you can save more than 200 gallons of water monthly, according to the EPA.

Cut water use further by limiting showers to five minutes and eliminating baths. Shower with your partner when you can. Save even more water by turning it off when you’re shampooing, shaving or lathering up, Consumer Reports suggests.

Replacing old sink faucets or showerheads with WaterSense models can save hundreds of gallons of water per year.

Laundry rooms account for nearly a fourth of household water use, according to the EPA. Traditional washing machines can use 50 gallons of water or more per load, but newer energy- and water-conserving machines use less than 27 gallons per load.

You can also cut back by doing full loads (but not overstuffing) and choosing the appropriate water level and soil settings. Doing the latter two can help high-efficiency machines use only the water that’s needed. If you have a high-efficiency machine, use HE detergent or measure out regular detergent, which is more sudsy and, if too much is used, can cause the machine to use more water, according to Consumer Reports.

Nationally, outdoor water use accounts for 30% of household use, according to the EPA. This percentage can be much higher in drier parts of the country and in more water-intensive landscapes, particularly in the West.

If you prefer to have a landscape, reduce your outdoor use by planting only plants appropriate for your climate or ones that are low-water and drought-resistant.

“If maintained properly, climate-appropriate landscaping can use less than one-half the water of a traditional landscape,” the EPA says.

The biggest water consumers outside are automatic irrigation systems, according to the EPA. To use only what’s necessary, adjust irrigation controllers at least once per month to account for weather changes. WaterSense irrigation controllers monitor weather and landscape conditions to water plants only when needed.

Climate change is contributing to the rise of superbugs, new UN report says | CNN



CNN
 — 

Climate change and antimicrobial resistance are two of the greatest threats to global health, according to a new report from the United Nations Environment Programme.

The report, titled “Bracing for Superbugs,” highlights the role of climate change and other environmental factors contributing to the rise of antimicrobial resistance. It was announced Tuesday at the Sixth Meeting of the Global Leaders Group on Antimicrobial Resistance in Barbados.

Antimicrobial resistance or AMR happens when germs such as bacteria, viruses and fungi develop the ability to defeat the medications designed to kill them.

“The development and spread of AMR means that antimicrobials used to prevent and treat infections in humans, animals and plants might turn ineffective, with modern medicine no longer able to treat even mild infections,” the UN Environment Programme said in a news release.

Roughly 5 million deaths worldwide were associated with antimicrobial resistance in 2019, and the annual toll is expected to increase to 10 million by 2050 if steps aren’t taken to stop the spread of antimicrobial resistance, according to the report.

In the US, there are nearly 3 million antimicrobial-resistant infections each year, and more than 35,000 people die as a result, the US Centers for Disease Control and Prevention says.

Antimicrobials are commonly used in cleaning products, plant pesticides and medications to kill and prevent the spread of germs among people, animals and crops.

Drug resistance can develop naturally, but experts say the overuse of antimicrobials in people, animals and food production has accelerated the process. The microorganisms that survive these chemicals are stronger and more powerful, and they can spread their drug-resistant genes to germs that have never been exposed to antimicrobials.

The focus so far has largely been on excessive antimicrobial use, but experts say there is growing evidence that environmental factors play a significant role in the development, transmission and spread of antimicrobial resistance.

“Climate change, pollution, changes in our weather patterns, more rainfall, more closely packed, dense cities and urban areas – all of this facilitates the spread of antibiotic resistance. And I am certain that this is only going to go up with time unless we take relatively drastic measures to curb this,” said Dr. Scott Roberts, an infectious diseases specialist at Yale School of Medicine, who was not involved with the new UN report.

The climate crisis worsens antimicrobial resistance in several ways. Research has shown that increased temperatures increase both the rate of bacterial growth and the rate of the spread of antibiotic-resistant genes between microorganisms.

“As we get a more extreme climate, especially as it warms, the gradients that drive the evolution of resistance will actually accelerate. So, by curbing temperature rises and reducing the extremity of events, we can actually then fundamentally curb the probability of evolving new resistance,” Dr. David Graham, a professor of ecosystems engineering at Newcastle University and one of the UN report’s authors, said at a news conference ahead of the report’s release.

Experts also say severe flooding as a result of climate change can lead to conditions of overcrowding, poor sanitation and increased pollution, which are known to increase infection rates and antimicrobial resistance as human waste, heavy metals and other pollutants in water create favorable conditions for bugs to develop resistance.

“The same drivers that cause environmental degradation are worsening the antimicrobial resistance problem. The impacts of antimicrobial resistance could destroy our health and food systems,” Inger Andersen, the UN Environment Programme’s executive director, said at the news conference.

Environmental pressures are creating bugs that thrive in the human body, which experts say is unusual for some species.

“There’s one hypothesis from a prominent mycologist who suggests that the reason the body’s temperature is 98.6 is because that is the temperature where fungi can’t grow that well. And so, now we’re seeing Candida auris and some of the other new microbes that have come up that really grow quite well – even at temperatures of 98.6 in the human body. And so I think climate change, really selecting for these organisms to adapt to a warmer climate, is going to increase the odds that there’s infection in humans,” Roberts said.

Such opportunistic infections jeopardize medical advancements like joint replacements, organ transplants and chemotherapy – procedures in which patients have a significant risk of infection and require effective antibiotics.

Drug-resistant infections can make treatment difficult or even impossible. Roberts says that resorting to “last-ditch treatments” is “never a good scenario from the patient level because there are reasons we don’t use them up front,” such as organ toxicity and failure.

“When somebody does present with a drug-resistant bacteria or fungus and we really need to rely on one of these last-line antibiotics, it’s usually a challenge to treat from the outset. And so the patients really don’t do as well as a result,” he said. “In rare circumstances, we run out of options entirely, and in that case, there’s really nothing we can do. Fortunately, those cases remain quite rare, but I am certain that with this growing antibiotic resistance problem, we’ll see these increasing frequency over time.”

Experts say that both climate change and antimicrobial resistance have been worsened by and can be improved by human actions. One critical step is to limit antibiotic overuse and misuse.

“Antibiotics and antifungals do not work on viruses, such as colds and the flu. These drugs save lives. But, anytime they are used, they can lead to side effects and antimicrobial resistance,” the UN report’s authors wrote.

The authors also emphasize that the health of people, animals, plants and the environment are closely linked and interdependent, and they call on governments to identify policies to limit antibiotic use in agriculture and reduce environmental pollution.

Finally, experts say, steps to reduce climate change are steps to limit antimicrobial resistance.

“Whatever we can do on an individual level to kind of reduce the impact of climate change, really, that’s kind of only worsening this problem, as well as pollution and urbanization and in dense, crowded areas. Although I know from the individual level that’s a hard thing to change,” Roberts said.

Pandemic fueled alcohol abuse, especially among women, but there are treatment options | CNN

Editor’s Note: In the final two episodes of “This Is Life With Lisa Ling,” the series explores alcoholism in America (at 9 p.m. ET Sunday) and interracial marriages (at 10 p.m. ET Sunday).



CNN
 — 

Brook was 34 years old when her use of alcohol escalated, a way of coping with a breast cancer diagnosis.

“I just decided I’m not gonna go through this straight,” she told Lisa Lang in an episode of “This Is Life With Lisa Ling,” airing at 9 p.m. ET Sunday on CNN.

“I would drink before I went to my chemo sessions. It became more and more of a coping mechanism,” said Brook, who did not want to use her last name.

Brook survived the bout with cancer but says she became dependent on alcohol — and the pandemic only made it worse.

“When Covid started and I was home, I started drinking more and more and more,” said Brook, now 42. “I started not being able to eat, I started throwing up more often, and then I started throwing up blood.”

She recently ended up in the hospital, diagnosed with cirrhosis of the liver and a bad bleed from ulcers, which doctors said could take her life if not quickly treated.

“When they were talking to me afterwards, they said, ‘If you keep going like this, you’ll be dead in a year,’ ” Brook told Ling.

Alcohol use disorder is defined as compulsively using alcohol despite negative consequences on relationships and one’s ability to function at work, school or in the community. Over time, excessive alcohol use may even rewire the brain, making booze as desirable as natural rewards such as food or sex, experts say.

Researchers at University of California, Los Angeles showed pictures of alcoholic drinks to people who are and are not addicted while scanning their brains. Regions of the brain associated with craving, pleasure and reward lit up significantly more in those with an alcohol use disorder.

“It’s much more of a medical and brain disease than we initially thought,” Lara Ray, a clinical psychologist who runs the UCLA Addictions Lab, told Ling.

In addition, just one pint of beer or average glass of wine a day may begin to shrink the overall volume of the brain. The brains of nondrinkers who began consuming an average of one alcohol unit a day showed the equivalent of half a year of aging, according to a study published in March.

The damage worsens as the number of daily drinks rises, the study found — drinking four alcohol units a day aged a person’s brain by more than 10 years.

Alcohol use disorder is a growing problem in the United States, which experts say has been enhanced by the pandemic, especially among women.

“Last year, I took care of two women who were in their early 20s who had cirrhosis and needed liver transplants, and I’ve never seen that before in my entire career,” Dr. James Burton, medical director of liver transplantation at the University of Colorado School of Medicine in Aurora, told Ling.

A recent study found a significant increase in alcohol-associated liver disease and a 15% higher rate of waiting lists and subsequent liver transplants between 2020 and 2021 — the greatest increase occurred in young adults.

Since the pandemic’s onset, statistics show an overall 14% increase in the number of drinking days per month, but a “41% increase in heavy drinking days among women,” Dr. Sarah Wakeman, medical director of the Substance Use Disorders Initiative at Massachusetts General Hospital, told CNN in January.

Why? Pre-pandemic mom wine culture, which “normalized and even glorified” drinking, is partly to blame, said Dr. Leena Mittal, chief of the women’s mental health division in the department of psychiatry at Brigham and Women’s Hospital in Boston.

In addition, “studies have shown the complexities of balancing home, work and caregiving responsibilities during the pandemic have fallen disproportionately on women,” Mittal said earlier.

Women are especially sensitive to the effects of alcohol, according to the National Institute on Alcohol Abuse and Alcoholism. Alcohol-related problems appear sooner and at lower drinking levels than in men, said the institute, part of the US National Institutes of Health.

Women are more susceptible to alcohol-related brain damage and heart disease than men, and studies show women who have one drink a day increase their risk of breast cancer by 5% to 9% compared with those who abstain.

Pandemic lockdowns also forced many people to live and work from home — sometimes alone. A July study found drinking alone during adolescence and young adulthood can strongly increase the risk for alcohol abuse later in life, especially if you are a woman.

Victoria, who also did not want to use her last name, told Ling she began drinking as a teenager. Now 55, she still “can’t control it. It’s like a tension that builds up. And so then when I do drink, it’s like, ‘Ah! I’m drinking,’ you know, so it’s way too much, way too fast.”

Victoria says she continues to crave alcohol but goes regularly to support meetings for addiction recovery after moving in with her mother during the pandemic.

Binge drinking — defined as more than four drinks for women and five for men within a few hours — is on the rise. According to a study published in June, even older people who consider themselves moderate users of alcohol are downing multiple drinks in one sitting.

People who binged were about five times more likely to experience numerous alcohol problems, including injuries, emotional or psychological issues, and alcohol dependence at work or school or while caring for children, the study found.

“What this means is that an individual whose total consumption is seven drinks on Saturday night presents a greater risk profile than someone whose total consumption is a daily drink with dinner, even though their average drinking level is the same,” study coauthor Charles Holahan, professor of psychology at the University of Texas at Austin, told CNN previously.

The US Food and Drug Administration has approved only three drugs designed to reduce alcohol use since 1951: disulfiram, which causes headaches, nausea and vomiting when mixed with alcohol; acamprosate, which works on the reward centers of the brain to reduce alcohol cravings; and naltrexone, which reduces cravings and appears to help with heavy drinking.

There is help. Find it here

  • The National Institute on Alcohol Abuse and Alcoholism has a tool called the NIAA Alcohol Treatment Navigator that “helps adults find alcohol treatment for themselves or an adult loved one.” For teens, the institute recommends these resources.
  • The Substance Abuse and Mental Health Services Administration has a free, confidential National Helpline active 24/7/ 365 days a year to provide information and treatment referrals to local treatment facilities, support groups and community-based organizations: 800-662-HELP (4357) and 800-487-4889 (TTY option).
  • All three have significant side effects that can deter people from using them consistently.

    Researchers continue to experiment with various drugs to see if they can help cure cravings without major side effects. While not FDA-approved, the anticonvulsant drug topiramate has shown promise in some clinical trials but may affect cognition and memory. Other anticonvulsant drugs, such as zonisamide and gabapentin, and a smoking cessation drug called varenicline have shown mixed results.

    At Ray’s lab at UCLA, small clinical trials have found promising results from the neuromodulator ibudilast, which hindered cravings and reduced the odds of heavy drinking for some people by 45%.

    For Billy Flores, 45, the change happened quickly.

    “In the first two days, I was upset in the stomach, but by the third day I was on it, I was off of alcohol, which is pretty amazing I thought,” he told Ling about using ibudilast.

    Bill has struggled with alcohol but says he has found hope with a clinical trial.

    Additional studies are needed to see if the benefits hold true for larger populations.

    In the meantime, there are gold standard treatments for alcohol use disorder that don’t involve medications. Those include Alcoholics Anonymous and Self-Management and Recovery Training 12-step programs, cognitive behavioral treatments and mindfulness-based approaches.

    A large 2006 clinical trial found behavioral interventions can be as effective as drugs — in fact, most of the medication clinical trials done to date have also included some form of social or behavioral treatment in combination with drugs.

    Having support is critical to keeping a positive mindset that will ultimately win the battle with alcohol, experts say.

    Brook agrees.

    “When I was doing my therapy intake for rehab, one of the questions was, ‘What made you decide to do this?’ And I said, ‘I’m better than this,’ ” she told Ling.

    “I still like to think that even with the relapses, I’m gonna still be that person who gets right back up and tries again.”
