The same artificial intelligence technique typically used in facial recognition systems could help improve prediction of hailstorms and their severity, according to a new, National Science Foundation-funded study. Instead of zeroing in on the features of an individual face, scientists trained a deep learning model called a convolutional neural network to recognize features of individual storms that affect the formation of hail and how large the hailstones will be, both of which are notoriously difficult to predict. The promising results highlight the importance of taking into account a storm's entire structure, something that's been challenging to do with existing hail-forecasting techniques.

A new study shows that graphene sheets can block the signals mosquitoes use to identify a blood meal, potentially enabling a new chemical-free approach to mosquito bite prevention. Researchers showed that multilayer graphene can provide a twofold defense against mosquito bites. The ultra-thin yet strong material acts as a barrier that mosquitoes are unable to bite through. At the same time, experiments showed that graphene also blocks chemical signals mosquitoes use to sense that a blood meal is near, blunting their urge to bite in the first place. The findings suggest that clothing with a graphene lining could be an effective mosquito barrier.

The dangerous Delta variant of the coronavirus is spreading so quickly in the United States that it's likely the mutant strain will become predominant in the U.S. within weeks, according to a new analysis.

The variant, first identified in India, is the most contagious yet and, among those not yet vaccinated, may trigger serious illness in more people than other variants do, say scientists tracking the spread of infection.

The Delta variant apparently already accounts for at least 14% of all new infections, according to the research analysis posted online Monday of more than 242,000 infections nationwide over the last six months.

Another reason to get vaccinated

"It definitely is of concern," says William Lee, the vice president of science at Helix, which is under contract with the Centers for Disease Control and Prevention to help track the variants.

"Just the fact that it's so transmissible means that it's it's dangerous," Lee says, "and so I think you'll see outbreaks of Delta around the country and more people will get sick from it."

Helix launched the study when researchers spotted a drop in the prevalence of the Alpha variant, a contagious strain first spotted in the U.K. that had quickly become the dominant variant in that country and the U.S.

The researchers discovered the drop in relative frequency of the Alpha variant in their spot checks of strains circulating in the U.S. was due to a rapid increase in two other variants: the Gamma variant, first spotted in Brazil, and the Delta variant. The Gamma variant may be slightly better than the original strain at outmaneuvering the vaccines, researchers say.

"It looks like both of them are going to slowly push out Alpha," says Lee, whose study has not yet been peer-reviewed but has been posted on a pre-print server.

How Delta could prompt another U.S. COVID-19 surge

All the vaccines authorized for use in the U.S. appear, in general, to provide powerful protection against all the variants, including Delta. But the rapid spread of the variants is still raising concern because of the large number of people who remain unvaccinated.

"There still are big portions of the country where the rates of vaccination are quite low," notes Dr. Jeremy Luban, a virologist at the University of Massachusetts Medical School. "And, in fact, the Helix paper shows that this Delta variant is increasing in frequency — the speed at which it's increasing in frequency is greatest in those areas where vaccination rates are lowest."

The Delta variant could trigger yet another moderate surge of infections through many parts of the U.S. because of these pockets of unvaccinated people, according to a recent set of projections from the COVID-19 Scenario Modeling Hub, which is helping the CDC plot the future course of the pandemic.

The projections indicate that infections could start to rise again as soon as some time in July, especially if the vaccination campaign continues to stall.

"For the most part, it's a moderate resurgence," says Justin Lessler, an epidemiologist at Johns Hopkins University who is helping coordinate the hub.

"We're not having massive epidemics at a national level, but we have this kind of continuation of the virus just sticking around and keeping us on our toes," Lessler says. "And in specific places there could be substantial epidemics still."

The Biden administration is quietly engineering a series of expansions to Medicaid that may bolster protections for millions of low-income Americans and bring more people into the program.

Biden's efforts — which have been largely overshadowed by other economic and health initiatives — represent an abrupt reversal of the Trump administration's moves to scale back the safety-net program.

The changes could further boost Medicaid enrollment — which the pandemic has already pushed to a record 80.5 million. Some of the expansion is funded by the COVID-19 relief bill that passed in March, including coverage for new mothers.

Others who could also gain coverage under Biden are inmates and undocumented immigrants. At the same time, the administration is opening the door to new Medicaid-funded services such as food and housing that the government insurance plan hasn't traditionally offered.

"There is a paradigm change underway," said Jennifer Langer Jacobs, Medicaid director in New Jersey, one of a growing number of states trying to expand home-based Medicaid services to keep enrollees out of nursing homes and other institutions.

"We've had discussions at the federal level in the last 90 days that are completely different from where we've ever been before," Langer Jacobs said.

Taken together, the Medicaid moves represent some of the most substantive shifts in federal health policy undertaken by the new administration.

"They are taking very bold action," said Rutgers University political scientist Frank Thompson, an expert on Medicaid history, noting in particular the administration's swift reversal of Trump policies. "There really isn't a precedent."

The Biden administration seems unlikely to achieve what remains the holy grail for Medicaid advocates: getting 12 holdout states, including Texas and Florida, to expand Medicaid coverage to low-income working-age adults through the Affordable Care Act.

And while some of the recent expansions – including for new mothers -- were funded by close to $20 billion in new Medicaid funding in the COVID relief bill Biden signed in March, much of that new money will stop in a few years unless Congress appropriates additional money.

The White House strategy has risks. Medicaid, which swelled after enactment of the 2010 health law, has expanded further during the economic downturn caused by the pandemic, pushing enrollment to a record 80.5 million, including those served by the related Children's Health Insurance Program. That's up from 70 million before the COVID crisis began.

The programs now cost taxpayers more than $600 billion a year. And although the federal government will cover most of the cost of the Biden-backed expansions, surging Medicaid spending is a growing burden on state budgets.

The costs of expansion are a frequent target of conservative critics, including Trump officials like Seema Verma, the former administrator of the Centers for Medicare & Medicaid Services, who frequently argued for enrollment restrictions and derided Medicaid as low-quality coverage.

But even less partisan experts warn that Medicaid, which was created to provide medical care to low-income Americans, can't make up for all the inadequacies in government housing, food and education programs.

"Focusing on the social drivers of health ... is critically important in improving the health and well-being of Medicaid beneficiaries. But that doesn't mean that Medicaid can or should be responsible for paying for all of those services," said Matt Salo, head of the National Association of Medicaid Directors, noting that the program's financing "is simply not capable of sustaining those investments."

Restoring federal support

However, after four years of Trump administration efforts to scale back coverage, Biden and his appointees appear intent on not only restoring federal support for Medicaid, but also boosting the program's reach.

"I think what we learned during the repeal-and-replace debate is just how much people in this country care about the Medicaid program and how it's a lifeline to millions," Biden's new Medicare and Medicaid administrator, Chiquita Brooks-LaSure, told KHN, calling the program a "backbone to our country."

The Biden administration has already withdrawn permission the Trump administration had granted Arkansas and New Hampshire to place work requirements on some Medicaid enrollees.

In April, Biden blocked a multibillion-dollar Trump administration initiative to prop up Texas hospitals that care for uninsured patients, a policy that many critics said effectively discouraged Texas from expanding Medicaid coverage through the Affordable Care Act, often called Obamacare. Texas has the highest uninsured rate in the nation.

The moves have drawn criticism from Republicans, some of whom accuse the new administration of trampling states' rights to run their Medicaid programs as they choose.

"Biden is reasserting a larger federal role and not deferring to states," said Josh Archambault, a senior fellow at the conservative Foundation for Government Accountability.

But Biden's early initiatives have been widely hailed by patient advocates, public health experts and state officials in many blue states.

"It's a breath of fresh air," said Kim Bimestefer, head of Colorado's Department of Health Care Policy and Financing.

Chuck Ingoglia, head of the National Council for Mental Wellbeing, said: "To be in an environment where people are talking about expanding health care access has made an enormous difference."

Mounting evidence shows that expanded Medicaid coverage improves enrollees' health, as surveys and mortality data in recent years have identified greater health improvements in states that expanded Medicaid through the 2010 health law versus states that did not.

Broadening eligibility

In addition to removing Medicaid restrictions imposed by Trump administration officials, the Biden administration has backed a series of expansions to broaden eligibility and add services enrollees can receive.

Biden supported a provision in the COVID relief bill that gives states the option to extend Medicaid to new mothers for up to a year after they give birth. Many experts say such coverage could help reduce the U.S. maternal mortality rate, which is far higher than rates in other wealthy nations.

Several states, including Illinois and New Jersey, had sought permission from the Trump administration for such expanded coverage, but their requests languished.

The COVID relief bill — which passed without Republican support — also provides additional Medicaid money to states to set up mobile crisis services for people facing mental health or substance use emergencies, further broadening Medicaid's reach.

And states will get billions more to expand so-called home and community-based services such as help with cooking, bathing and other basic activities that can prevent Medicaid enrollees from having to be admitted to expensive nursing homes or other institutions.

Perhaps the most far-reaching Medicaid expansions being considered by the Biden administration would push the government health plan into covering services not traditionally considered health care, such as housing.

This reflects an emerging consensus among health policy experts that investments in some non-medical services can ultimately save Medicaid money by keeping patients out of the hospital.

In recent years, Medicaid officials in red and blue states — including Arizona, California, Illinois, Maryland and Washington — have begun exploring ways to provide rental assistance to select Medicaid enrollees to prevent medical complications linked to homelessness.

The Trump administration took steps to support similar efforts, clearing Medicare Advantage health plans to offer some enrollees non-medical benefits such as food, housing aid and assistance with utilities.

But state officials across the country said the new administration has signaled more support for both expanding current home-based services and adding new ones.

That has made a big difference, said Kate McEvoy, who directs Connecticut's Medicaid program. "There was a lot of discussion in the Trump administration," she said, "but not the capital to do it."

Other states are looking to the new administration to back efforts to expand Medicaid to inmates with mental health conditions and drug addiction so they can connect more easily to treatment once released.

Kentucky health secretary Eric Friedlander said he is hopeful federal officials will sign off on his state's initiative.

Still other states, such as California, say they are getting a more receptive audience in Washington for proposals to expand coverage to immigrants who are in the country without authorization, a step public health experts say can help improve community health and slow the spread of communicable diseases.

"Covering all Californians is critical to our mission," said Jacey Cooper, director of California's Medicaid program, known as Medi-Cal. "We really feel like the new administration is helping us ensure that everyone has access."

The Trump administration moved to restrict even authorized immigrants' access to the health care safety net, including the "public charge" rule that allowed immigration authorities to deny green cards to applicants if they used public programs such as Medicaid. In March, Biden abandoned that rule.

California on Tuesday moved another step closer to decriminalizing psychedelics — amid a debate over whether their prohibition is an outdated remnant of the War on Drugs — after the author removed a substance (ketamine) from the bill that opponents said can be used as a date-rape drug.

The bill would allow those 21 and older to possess for personal use and “social sharing” psilocybin, the hallucinogenic component of so-called magic mushrooms. It also covers psilocybin, dimethyltryptamine (DMT), ibogaine, mescaline excluding peyote, lysergic acid diethylamide (LSD) and 3,4-methylenedioxymethamphetamine (MDMA, often called ecstasy).

The bill bars sharing with those under age 21 or possessing the substances on school grounds. It would remove the state’s ban on cultivating or transferring mushroom spores or other material containing psilocybin or psilocybin.

Even if California makes the bill law, the drugs would still be illegal under federal law.

A National Science Foundation-funded study found that Charles Darwin's famous finches defy what has long been considered a key to evolutionary success: genetic diversity. The research on finches of the Galapagos Islands could change the way conservation biologists think about a species' potential for extinction in naturally fragmented populations. Researchers examined 212 tissue samples from museum specimens and living birds. Some of the museum specimens in the study were collected by Darwin himself in 1835. Only one of the extinct populations, a species called the vegetarian finch, had lower genetic diversity compared to modern survivors. Specifically, researchers believe a biological phenomenon called sink-source dynamics is at play in which larger populations of birds from other islands act as a "source" of immigrants to the island population that is naturally shrinking, the "sink." Without these immigrant individuals, the natural population on the island likely would continue to dwindle to local extinction. The immigrants have diverse genetics because they are coming from a variety of healthier islands, giving this struggling "sink" population inflated genetic diversity.

La Soufrière, the highest peak on the Caribbean island of St. Vincent, began to explosively erupt Friday morning, forcing thousands to evacuate as ash and smoke filled the sky.

And a larger eruption may be on the way.

Richard Robertson, a geologist with the University of the West Indies Seismic Research Centre, said the volcano is in its explosive eruption phase. The initial explosion of dust and debris St. Vincent experienced Friday is likely just the beginning.

"The explosive eruption has started and it is possible you could have more explosions like these," he said during a press conference. "The first one is not necessarily the worst one, the first bang is not necessarily the biggest bang this volcano will give."

Ralph Gonsalves, the prime minister of St. Vincent and the Grenadines, ordered residents on the northern side of the island to evacuate Thursday out of the red volcano danger zone. The Associated Press reported some 16,000 people were forced to flee their homes.

Soot and ash fell throughout the night, blanketing neighborhoods and streets across the island Saturday morning. Robertson said the ash is expected to fall for the next handful of days, possibly even weeks.

The dome of the volcano, which is about 3,100 feet long and more than 820 feet wide, was destroyed in Friday's eruption, catapulting 460 million cubic feet of debris into the atmosphere. The ash could reach as far as Jamaica and parts of South America, Robertson said.

The last time La Soufrière had a major eruption was in 1979, which lasted several weeks. This eruption, Robertson said, "will more than likely be a bigger eruption than 1979 was." He added, "We don't know how much material is down there that wants to come out."

The fine ash particles, which are difficult to clean up, pose a respiratory risk, especially for people with underlying issues. Robertson recommended that individuals who have decided to stay on the island do their best to clean the ash before it settles or gets wet.

With more potential eruptions looming, Robertson advised residents to move as far south as possible. La Soufrière could be heard rumbling and grumbling throughout the night, he said, from the sound of magma moving inside the volcano.

To help keep weak swimmers safe, stay "touch-close" and don't rely on a busy lifeguard to be the only eyes on a crowded pool or beach. It's best, say experts working to prevent drownings, to designate a nondrinking adult to scan the water at any pool party or beach outing, and to rotate that "watching" shift every 30 minutes to keep fresh eyes on the kids.; Credit: Imgorthand/Getty Images

I'm going to let you in on one of the most important lessons I learned early on, in my years of training to become a doctor: Absolutely anyone can drown, or lose a loved one to a drowning.

The Centers for Disease Control and Prevention estimates that more than 3,900 people die from unintentional drowning in the US each year — with one in five under 14-years-old. And for each pediatric fatality, another five children require emergency care for nonfatal drownings that can cause irreversible organ damage.

Every patient or family I've cared for after a drowning accident has said they didn't think it could happen to them. And yet, it happens, along with the cruel "if onlys" that haunt cautious and well-intentioned people in the aftermath: "If only I'd done something different, or known what to look for." I hear this again and again, especially from those who've lost a child.

Unfortunately, research shows that in the majority of drowning cases, the child was being supervised by an adult when the accident happened. So, as our summer of post-vaccination reunions and vacations heats up, remember just how vulnerable kids are in water. The rate of admissions for nonfatal drownings at the Arnold Palmer Children's Hospital in Orlando, for example, was already double in May what it was in the last three years at that same time.

Among basic water supervision precautions, a few potentially life-saving details are often overlooked. Here are some essentials to help keep our young swimmers safe this summer:

Follow the 'arm's length' rule

It may sound commonsensical to stay close by when kids are in or near a pool or other body of water, but it's important to know what safety experts consider close enough supervision to avoid a drowning event.

The American Academy of Pediatrics recommends that adults who are supervising a child of any age who isn't a strong swimmer should be within one arm's length at all times when kids are in the water, offering "touch supervision" this way.

Dr. Andrew Schmidt, a lifeguard-turned-ER doctor at University of Florida Health-Jacksonville and an expert in water safety, notes the definition of a "strong swimmer" is subjective — and overestimating a child's independence in the water has led to tragic accidents.

Schmidt falls back on the way the American Red Cross, a longtime leader in teaching water safety, defines a "water competent" swimmer. According to the Red Cross guidelines , someone is water-competent if they find themselves in water over their head and are able to:

• Swim to the surface after being submerged, then float or tread water for at least one minute.
• Swim in a full circle and find an exit, then swim about 25 yards to that exit.
• Get out of the water on their own, which means exiting the water without a ladder if they're in a pool.

That's a good starting point for judging kids' vulnerability in the water, but adults still need to stay vigilant. "Even a strong swimmer can get into trouble," warns Dr. Terri McFadden, a professor in the department of pediatrics at Emory University's School of Medicine and medical director of the Injury Free Coalition for Kids in Atlanta.

Treat water safety supervision like a job

Calling appropriate water supervision an "intense job," McFadden is quick to remind the parents of her patients to stay alert even if the child is a proficient swimmer.

Having older kids or young teens — or adults that are weak swimmers — acting as chaperones isn't safe, she says. And if you're the adult in charge, doing anything that draws your eyes away from the water for just a moment is risky. Reading, using your phone in any capacity, socializing, fiddling with the bluetooth speaker or doing household chores – all such lapses are dangerous when children are swimming or playing in water. Drowning accidents have happened in the time it takes for a caretaker to run inside just long enough to put wet clothes in the dryer, or while they were looking on from a kitchen window and doing dishes. No distraction is quick enough to be safe when it comes to kids in or around water – not seconds, not minutes.

Mcfadden is among many leaders in child safety who recommend assigning an adult "watcher" at the pool or waterfront who can agree to be totally attentive for a brief period of time (15 to 30 minutes or so), then switching to another watcher in intervals; short spurts of duty making it easier to stay focused. It doesn't matter at a pool party that there are a dozen responsible adults nearby; if there isn't one pair of mature eyes devoted to watching the young swimmers 100% of the time, the risk of a deadly accident goes up.

Similarly, it's never safe to simply rely on lifeguards. Though trained to scan for emergencies and quickly respond, they can also get distracted, especially when there are lots of people bobbing along or jumping in and out of the water.

Stay sober when you're the adult in charge

There's also been a well-documented spike in alcohol use during the pandemic, and coupling that increase with an uptick in warm weather and waterside celebrations with friends and family can be a drowning accident waiting to happen.

Not only does alcohol lower our level of alertness and slow the reflexes needed to act quickly when we spot danger, it will also make swimming and helping someone to safety slower and more difficult as well.

And I'm not just talking about avoiding being drunk; cognitive processes and reflexes can slow after just a drink or two. Should something bad happen, it's not worth the heartbreak of wondering if the outcome could have been different without alcohol — something I've witnessed first-hand among some families of drowning victims.

The safest bet is to designate one fully sober adult as the watcher for 15 to 30 minutes at a time when kids are in or near the water. "Sober" means those adults agree to not use any mind-altering substances in that time — not alcohol, marijuana or even some allergy medicines or other prescription drugs that can cause drowsiness.

Use the safest life jacket, but don't rely on it alone

Life jackets do provide an added layer of protection against drowning, and most states require kids to wear them at all times when on a boat — regardless of their swimming strength.

Water safety and drowning experts recommend kids only wear life vests or jackets that are US Coast Guard-approved, which includes many different brands and will be noted clearly on the tag or printed onto the life jacket itself, along with a number that tells you what federal regulation it's approved under.

Pay close attention to what's printed there; the labels will tell you if it's not meant for weak or non-swimmers. You'll also find the weight range the vest is designed to fit. It should be nice and snug; wearing a loose life vest is like not wearing one at all.

Schmidt also cautions parents against relying on any unregulated flotation devices — including arm floaties, swimsuits with built-in floats or blow up neck rings. They may be cute, but can provide a false sense of safety that supports distracted supervision, he says.

Don't let shallow water deceive you

The risk to kids isn't equal to the depth of the water when we're talking about drowning. Small children can drown in baby pools, bathtubs or even household water buckets or tide pools — anything with enough water in it to cover their mouth and nose if they can't lift themselves out easily. They need adult supervision in these places, too.

And be forewarned — though child gates, locks and other safety measures are additional safety layers, if you've ever seen a kid use an iPhone you know that they're smart, and craftier than we realize. Most can still problem-solve their way around those barriers and into the water no matter the physical precautions.

Be ready to recognize what drowning or distress looks like

Parents and caretakers are often surprised to hear that drowning can look like nothing you'd notice, hear, or even expect — which is why it takes 100% visual and/or touch supervision to pick up the signs. The splashing, yelling and commotion you've seen in movies could certainly be a signal a child is in trouble, but it doesn't always happen that way.

Instead, be on the lookout for subtle and quick: a child motionless or face down in water or swimming upright but not making any progress forward; a lowered head, or a head tilted way back or with hair covering the eyes or face; a look of fear or doom in a child's eyes; or perhaps just a constant gaze toward shore or an exit/ladder. And a child that jumps or dives into the water but doesn't come up quickly could be missed without sharp visual supervision.

A swimmer of any skill level might need your help, and it can often take all of our senses on full-alert to identify a drowning in progress.

Swim classes are available for even very young kids. Enroll your child ASAP

Many 1-year-old babies can benefit from swim classes taught by a skilled instructor, according to the AAP. Children develop along different timelines, so check with your doctor to see if your child's ready to start.

And swim classes aren't just for beginners or kids — people of any age or ability can benefit. Even if you already know the fundamentals, swim instruction will help you expand your skills and be even safer in the water. Many instructors nowadays teach safety tactics like safer ways to jump into the water, how to safely escape an ocean's riptide or undertow, and how to save others from drowning without putting yourself in danger.

You can find classes through community pools, health departments or regional chapters of the American Red Cross or YMCA; some local nonprofits offer scholarships, so cost shouldn't be a barrier. Plus, the same groups can help you find CPR classes, which is a must for all chaperones and other adults — whether or not water is involved.

It's impossible to fully control environments where water and kids mix, but what we know about drowning is this: Sharp-eyed, adult supervision is key to prevention. And parents can't do it alone — if we all share the responsibility whenever we're near the water, we can save lives.
