Sunscreen gets an upgrade | Investors Lab
There are hundreds of brands of sunscreen available in the United States, but not one of them contains an ingredient we all need. Bemotrizinol, a highly effective, broad-spectrum chemical ultraviolet ray blocker, has been available in Europe for decades but absent from U.S. shelves. The regulatory bottleneck was driven by a 2011 U.S. Food and Drug Administration policy classifying sunscreens as drugs. While the classification remains, consumers and innovators can welcome the news that the FDA has officially approved bemotrizinol, effective August 9, 2026. Science News's Meghan Rosen provides the coverage.

At Family Science Night, Wonder Comes Before Answers.
BAR HARBOR—Family Science Night isn’t really about science. It’s about wonder. It’s about watching a five-year-old realize that the tiny creature under a microscope is a real living thing. It’s about a teenager discovering that the scientist explaining genetics or regeneration isn’t much older than they are. It’s about parents seeing curiosity spread across a child’s face the way excitement spreads across a crowd at a Fourth of July parade. For one evening, families realize that the laboratory isn’t some secretive place where knowledge is hidden behind white coats and closed doors. They learn that the lab is a place their neighbors work, their friends’ parents work, and it becomes a place where questions matter more than answers. It’s a place where wonder is the origin for knowledge. At the lab, children learn that it’s okay not to know. Adults remember that they once asked “Why?” about everything. Scientists are reminded why they fell in love with discovery in the first place. There are experiments, games, obstacle courses, and demonstrations, of course. But those are really just invitations—to touch, to explore, to laugh, to make mistakes, and to ask one more question. In a world that often rewards certainty, Family Science Night celebrates curiosity. And perhaps that’s its greatest gift. Long after the microscopes are packed away and the experiments are over, what families take home isn’t just a few new facts about biology. They take home the feeling that discovery belongs to everyone—that science isn’t something happening somewhere else by someone else. It’s simply what happens when people are given permission to wonder. A Family Science Night at the Mount Desert Island Biological Laboratory is one of those rare community events where children and adults can experience science as something they do, not just something they read about. Hands on discovery allows hands-on learning and joy. Real scientists, some local, some scientist-interns (but still scientists) just in college make science real, approachable, and exciting. And there, complex ideas like forever chemical-filtration, DNA and so much more become not complex. Instead, they become fun. Summer fellows are challenged to explain cutting-edge biomedical research in ways a first-grader—and their grandparent—can understand. Past activities have explored gene expression, kidney function, axolotl regeneration, worms, microplastics, and phytoplankton through games and creative demonstrations. Though it’s called family night, you can also see adults going from station to station, exploring, learning together across ages. Family Science Night reflects the laboratory’s broader mission of breaking down barriers between researchers and the public, helping people understand how scientific discoveries relate to everyday life and the health of Maine’s environment. Family Science Night transforms a world-class research laboratory into a giant interactive classroom, where curiosity is encouraged, questions are celebrated, and families discover that science isn’t just something that happens in a lab—it’s an adventure anyone can join.

MAGA's attack on science is even worse than it looks
In my post on America’s 250-year anniversary, I argued that respect for the individual was the “secret sauce” in the U.S.’ long-lasting preeminence among nations. But it was certainly not the only factor. There were plenty of institutional innovations that helped the U.S. stay on top — economically, militarily, and in terms of the attractiveness of its society. One of these was American science. Today we take things like the modern research university, government grants for science, public-to-private research spinoffs, etc. for granted, but a lot of that infrastructure wasn’t there before World War 2. It was either invented or scaled up massively by the U.S. government in the postwar period, led by far-sighted scientist-bureaucrats like Vannevar Bush (pictured above). If you want to read about this history, a good place to start would be Jonathan Gruber and Simon Johnson’s excellent book Jump-Starting America. Those scientific institutions didn’t exist in a vacuum, however. They were backed by the U.S. government’s abiding faith in the power of science — and, even more fundamentally, by deep popular trust in the scientific enterprise. Science gave us radar and the atom bomb in wartime, and in peacetime it gave us plastics, vaccines, cheap food, and a thousand other things that made our lives easier. Science was also the driver behind American industry — chemicals, aerospace, telecommunications, computers, electronics, and so on. We owed science our jobs, our livelihoods, our comfortable living standards, and our greatness and power as a nation. It’s little wonder that both political parties, even as they fought viciously over other issues, were steadfast in their support of science. For a long time, the only people who distrusted science were a hippie fringe on the left who disliked modernity (or thought they did, anyway), who also disliked American industry and American power, and who subscribed to an early version of degrowth environmentalism. America’s scientific enterprise is still strong, especially compared to the systems in Europe, Japan, Korea, and other developed countries. It has lost a lot of ground to China in a relative sense, but a lot of that is because of China’s incredible growth; as China has poured untold amounts of money and talent into its research labs, spending and output have overtaken the U.S. by some measures. There are a few ways in which China’s rise creates problems for American science — for example, top scientists can choose to work in China instead of in the U.S. — and of course there’s the concern that China’s technological strength will help its military to reign supreme. But overall, China’s rise in science should be good for American science, since American scientists can use Chinese discoveries for free and build on them. The much bigger problem is that the scientific enterprise America built during and after World War 2 is now being threatened with absolute decline. The biggest problem, of course, is that much of the country — the Republican half — has basically lost faith in the scientific enterprise. To what degree this loss of faith is justified is an open question, and deserves to be discussed openly. But the larger point — that the system that powered American dominance is under threat — is true either way. Most Americans still trust science, but MAGA Republicans don’t There’s a myth, popular in right-wing circles, that scientists have lost the trust of regular Americans — either due to the increasingly left-wing composition of academic departments, or to misbehavior during Covid, or to DEI-related research taking over science, etc. This also fits with a wider narrative that Americans are losing trust in all of our institutions. But it just isn’t true. Poll after poll shows that on the whole, Americans still trust scientists and want to spend more on science. For example, here’s a Pew poll from late 2025 showing that although about a fifth of Republicans did lose confidence in science in 2020, two thirds still have at least “a fair amount” of confidence: That same poll found that scientists are among America’s most trusted groups — even better trusted than the military! In fact, Americans trust scientists more than people in most other countries do. Other polls show that although Republican trust in science has dropped somewhat, Republican support for spending more on science remains very strong: A Pew poll in 2023 found the exact same thing: So when MAGA types tell you about scientists losing their credibility, or a drop in trust in science, they’re only talking about themselves. Whatever left-wing politicization of science happened during the Biden administration — and there was definitely some of that — it was not enough to make most Republicans lose faith in the scientific enterprise, or favor research cuts in order to purge unwanted ideology from the system. That doesn’t mean I think progressives should continue down the path of politicizing scientific research. They should not, and Biden made real missteps in this area. Objectivity clearly matters for public trust of science in the long term. But as of right now, there’s no crisis of trust in science, except among the smallish minority of people who are running around screaming that there’s a crisis of trust in science. But despite science’s overwhelming popularity and public trust, Trump and his administration are launching an unprecedented and devastating attack on American science — cutting funding, and forcing science projects to undergo ideological review by government commissars.

New depression treatment targets the immune system instead of the brain
A surprising new approach to depression treatment is showing early promise — not by targeting brain chemicals, but by calming the immune system. In a small clinical trial, researchers found that an anti-inflammatory drug normally used for rheumatoid arthritis appeared to ease symptoms in people with hard-to-treat depression, while also reducing fatigue and anxiety and improving quality of life.
Ebola, chemical plants and health, hantavirus, common colds, heat and more
As they say, bugs have ears. Public health has had a relentless May. Chemical plant (near) explosions, Ebola, hantavirus, and that's before you even get to the usual suspects: common colds, heat, and ticks. Here’s an attempt to keep you up to speed and, more importantly, what it means for you and your community. But first, an announcement: World Cup The World Cup starts in 15 days (not like anyone is counting down), and we are hanging TVs in the Health Security Operations Center. It’s going to be a gorgeous, chaotic celebration of basically every culture on earth. And it’s going to take a team effort—from communities to individuals, from public health to health care—to keep people healthy. That’s where you come in. If you’re going to the games or live within 30 miles of a stadium, we would love to hear from you. Sign up for a weekly survey here. Thanks to the more than 1,280 people who have already signed up…you will be hearing from us soon!! Global disease “weather report” Hantavirus: Two more cases The global count of cruise ship passengers with hantavirus has now increased to 13 cases (11 confirmed), with three deaths. The two new cases are overseas and among people who were already quarantining: A crew member in the Netherlands. A Spanish national passenger who was quarantining at home tested positive through daily monitoring. They are now in a biocontainment unit. In the U.S., everyone remains negative. There may be more cases, given that the incubation period of hantavirus (the time from exposure to infection) is 45 days. But this week, we will reach a major milestone: the median incubation window is 18 days, and that will pass on May 29. What this means for you: Your risk from this cruise ship outbreak remains essentially nil at this point. Ebola rages on in Central Africa Big thanks to Dr. Craig Spencer, a humanitarian physician who has treated and survived Ebola, for jumping in to provide the YLE community with an update. Craig, take it from here… The combined confirmed and suspected Ebola cases in DRC are now more than 1,000. All signs are pointing to a very long and catastrophic outbreak in Central Africa: This is a vast undercount. We know this because the test positivity rate is hovering around 50%, only 20% of contacts are being traced (and in some areas, no contacts at all), and more cases keep popping up with no known connection. This all points to widespread and undetected community transmission. This is in only a week of detection. Compared to previous outbreaks, the growth is very fast, as the huge West Africa outbreak in 2016 was first detected at 49 cases and rose to 208 cases a month later. It took four months for that outbreak to reach the size of the current one in the DR Congo. The cases are spread out across 16 health zones. There are now multiple epicenters, making containment very difficult. Next door in Uganda, the case count is seven. While this number is low compared to DRC, a concerning development is that two health care workers recently tested positive with uncertain exposure histories. If they weren’t treating known Ebola cases, this means it’s spreading undetected in Uganda as well. On the ground, backlash, including the burning of health centers, has emerged, a pattern seen in nearly every outbreak and rooted in deep community distrust. It often stems from outside actors working in communities without fully understanding or addressing local priorities. Affected populations may recognize the severity of Ebola while still holding other concerns as more pressing, such as where their loved ones are buried. Community trust is essential to an effective response, but difficult to build during an active emergency. It is best established long before a crisis begins. U.S. priorities are made clear, and may backfire. The U.S. Administration has shown that its first priority is keeping Ebola out, with helping end the outbreak in the DRC a secondary concern. That's meant travel restrictions broader than anything we've imposed before — covering travelers from across the region, and reportedly some green card holders and permanent residents as well. For example, just these past two days, news broke that high-risk American travelers will be subject to a mandatory quarantine in Kenya before they are allowed to return. If an American is infected, the U.S. government plans to send them to a hospital it is standing up from scratch in Kenya. (Currently, Americans who were in the area are allowed to return but are diverted to three airports—Houston, Atlanta, and DC—for further screening.) Past administrations have used travel notices and stepped-up screening; this goes much further. At first blush, these strict precautions may sound prudent. But this approach could backfire in three ways: Restrictions this blunt give people every reason to hide where they’ve been and whom they’ve been near — making the people we most need to find harder to track, not easier. They also breed a false sense that this is someone else’s problem. But diseases are humbling. They find the small cracks in even the most impenetrable-seeming defenses. Lives lost. There is no treatment for this Ebola strain, which means survival depends heavily on the quality of the health system. We have that system in the States, but we are choosing not to use it for infected Americans. This is unbelievable and infuriating. (See a deeper dive from me here.) The only real way to lower the risk to Americans — and everyone else — is to end the outbreak in the DRC and across the region. What this means for you: If you have travel plans to this region, it’s time to cancel them. This is a high-risk situation in Central Africa, and CDC released a Level 4 Travel Advisory. There is also great uncertainty if and when the Administration will let you back in. To the general public in the U.S., your risk remains very, very low right now. U.S. disease “weather report” Ticks: past peak season? Good news, especially for people in the Northeast and Midwest: tick numbers continue to decline. Though we are at the peak of the season, this unusually early year is trending favorably. Heat-related illnesses in the North Heat risk is certainly not blanketing the entire country yet, but this week it will be moderate in the Midwest and the Southeast. What this means for you: Be sure to check the CDC HeatRisk tool. A red day isn’t the best day for that soccer game for a kid with asthma, and a stretch of orange days is a great time to check on your elderly neighbor. Common colds surging As far as respiratory viruses go, the only thing really going around right now is the common cold. It is higher this year than last year, but should peak very soon before returning this fall. Spotlight: Chemical plants Over the weekend, YLE California covered the serious situation that unfolded around a chemical plant in Orange County, California. Thankfully, the worst-case scenario (a chemical explosion) was mitigated, but only through luck. The health implications in a densely populated area could have been catastrophic. As the situation was winding down, another chemical explosion struck Washington State. This one was fatal. Health officials say the risk to surrounding residents from chemicals in the air and ground remains low, though the community deserves far greater clarity. Clean air and clean water consistently rank as Americans’ top public health concerns — yet when chemical disasters strike, communities are too often met with reassurances rather than transparency and accountability. Residents near the 2023 East Palestine, Ohio train derailment, for example, are still waiting to understand the long-term impact on their health, with few clear answers. What this means for you: Many are wondering if facilities processing potentially dangerous materials are in their neighborhoods. This interactive map allows you to enter your ZIP code and see all facilities monitored by the EPA, including any violations. Good news Ebola vaccines and treatment for the Bundibugyo species are in development. Two vaccine platforms are being explored, at least one of which may be deployable in as little as 2 months. One vaccine is being developed by Oxford, and the other uses the same biotechnology as the FDA-approved Zaire species of Ebola. (It may provide cross-protection, but it’s unclear at this point.) On the treatment side, two promising monoclonal antibody cocktails are likely to be deployed, though doses are limited and logistical hurdles remain significant challenges.

This is good because the old name was medically misleading, leading to patients without visible cysts being dismissed or overlooked entirely. The WHO estimates that 70% of people with the condition remain undiagnosed. A more accurate name should improve recognition, reduce stigma, and ultimately help the millions of people living with this condition get diagnosed and treated sooner. Poll Loading...
