Did fuzzy coats help dinosaurs survive one of Earth’s worst extinctions?
As the monkeypox outbreak grows, the preferred vaccine to combat it is in short supply—a problem that’s only getting worse now that countries are expanding access to the vaccine. But there is a strategy that could double overnight the number of people who can be vaccinated: use a single shot instead of the recommended two.
Compelling data from monkey and human studies suggest...
For scientists, Roe’s end raises concerns about personal safety and professional choices
Dinosaurs lived in an endless summer, surrounded by steaming jungles and lush swamps—at least if movies such as
are to be believed. But that classic image is changing. Paleontologists now know some dinosaurs lived in comparatively chilly habitats with months of darkness and occasional snow on the ground. Frigid conditions like...
Ancient galaxy’s spin suggests universe’s first stars quickly coalesced into disks
Demonstrators gathered outside the Supreme Court the morning after the court overturned Roe v. Wade, effectively outlawing abortion in many states.

Astronomers have detected the rotation of a galaxy dating back to just 550 million years after the big bang, when the universe was 4% of its current age. The rotation suggests this baby galaxy was not an amorphous blob but rather an organized disk, just like the Milky Way and similar galaxies that have had more than 13 billion years to mature. It’s yet more evidence that galaxies grow...

When should U.S. research be stamped ‘top secret’? NSF asks for a new look at the issue
Female lineages anchored Pacific islands for 2000 years
The U.S. academic community is gearing up for a new effort to convince national policymakers that the benefits of keeping government-funded basic research out in the open—and not stamping it classified—far outweigh any threat to national security from sharing scientific findings.
The National Science Foundation (NSF) has asked the National Academies of Sciences, Engineering,...
News at a glance: Polio in London sewage, U.S. science spending bills, and new medical citations leader
Some 3000 years ago, people sailed toward the sunrise—and the last swatch of our planet uninhabited by humans: remote islands of the Pacific. By 1200 C.E.

WHO monkeypox decision renews debate about global alarm system for outbreaks
The viruses that cause Zika and dengue fever can’t get from person to person on their own—they need to hitchhike inside a mosquito. A new study suggests how they hail these rides: They make their victims smell more attractive to the blood-sucking bugs.
It’s "a big advance," says mosquito neuroscientist Laura Duvall of Columbia University, who wasn't connected to the...
Can former conservation ‘pirates’ help scientists study the oceans?
The World Health Organization (WHO) may have very high aspirations—“the attainment by all peoples of the highest possible level of health”—but when a new human disease begins to spread, or a known one behaves in unusual, threatening ways, it has few levers to pull. One important decision it can make, however, is declaring a Public Health Emergency of International Concern (PHEIC),...

Bad news for Paxlovid? Coronavirus can find multiple ways to evade COVID-19 drug
Pentagon UFO study led by researcher who believes in the supernatural
Prescriptions for Pfizer’s blockbuster drug Paxlovid have skyrocketed in recent weeks. That’s good news for many COVID-19 patients, as the pill has been proven to reduce severe disease from SARS-CoV-2 infections. But a bevy of new lab studies shows the coronavirus can mutate in ways that make it less susceptible to the drug, by far the most widely used of the two oral antiviral drugs...
Humans tamed the microbes behind cheese, soy, and more
When the U.S. government released
a much-anticipated report
on UFOs a year ago, many were perplexed that it couldn’t explain 143 of the 144 sightings it examined. (In the single closed case, the report concluded the mystery object was a large, deflating balloon.) "Where are the aliens?"
The truth was still out there. So was...
Ancient wolves give clues to origins of dogs
The burst of flavor from summer’s first sweet corn and the proud stance of a show dog both testify to the power of domestication. But so does the microbial alchemy that turns milk into cheese, grain into bread, and soy into miso. Like the ancestors of the corn and the dog, the fungi and bacteria that drive these transformations were modified for human use. And their genomes have...
Scientists pinpoint new brain target for antinausea drugs
Where and when dogs arose is one of the
biggest mysteries of domestication
. To solve it, researchers have tried everything from analyzing ancient dog bones to sequencing modern dog DNA—all with inconclusive results. Now, researchers have tried a new tack: figuring out where the ancient wolves that gave rise to dogs lived. The new study doesn’t close the case, but it...
Whether we’ve got the flu or have had too much to drink, most of us have experienced nausea. Unlike other universal sensations such as hunger and thirst, however, scientists still don’t understand the biology behind the feeling—or how to stop it. A new study in mice identifies a possible key player: specialized brain cells that communicate with the gut to turn off the feeling of...

Is the pediatric hepatitis outbreak real? A top WHO physician weighs in
Does warfare make societies more complex? Controversial study says yes
It has been 3 months since the United Kingdom reported severe, unexplained hepatitis was sending young children to hospitals in unusual numbers. The initial handful of cases reported in Scotland on 31 March were soon joined by dozens and then hundreds, primarily from Europe, the United States, and the United Kingdom. As of 22 June, the global total, from 33 countries, has swollen to...
Extreme temperatures in major Latin American cities could be linked to nearly 1 million deaths
War is hell. It breaks apart families, destroys natural resources, and drives humans to commit unspeakable acts of violence. Yet according to a new analysis of human history, war may also prod the evolution of certain kinds of complex societies. The twin developments of agriculture and military technology—especially cavalries and iron weapons—have predicted the rise of empires....
U.K. set to abandon Europe’s top science funding program, go it alone
In mid-January, the southern tip of South America suffered its
worst heat wave
in years. In Argentina, temperatures in more than 50 cities rose above 40°C, more than 10°C warmer than the typical average temperature in cities such as Buenos Aires. The scorching heat sparked wildfires, worsened a drought, hurt agriculture, and temporarily collapsed Buenos Aires’s...
Artificial intelligence could spot baby chickens in distress
A few months ago, Teresa Thurston, a cellular microbiologist at Imperial College London, could not have imagined losing her €1.5 million European research grant. But the United Kingdom’s role in the European Union’s €95 billion Horizon Europe funding program is now crumbling thanks to lingering Brexit disputes, forcing many U.K. grant winners like Thurston to give up grants they...
Chickens make more sounds than most of us realize. They cluck when content, squawk when frightened, and sing “buk, buk, ba-gawk” when laying an egg. Their chicks vocalize too, and they can vary that simple sound to signal pleasure or distress. Now, scientists have developed an artificial intelligence (AI) program that automatically identifies these SOS calls, an advance that could...

Warmer winters could wipe out Antarctica’s only native insect
NIH’s vaunted program for solving puzzling medical cases is running out of money
The Antarctic midge might be smaller than a pea, but it’s the continent’s largest land animal–and only native insect. The midge has clearly evolved to survive in extreme conditions, yet a warming climate could threaten its existence, a new study finds.
Unlike temperate-zone midges that swarm around water, the Antarctic midge (
‘Zombie papers’ just won’t die. Retracted papers by notorious fraudster still cited years later
Ten years ago, an athletic 12-year-old from Affton, Missouri, named Mitchell Herndon began to experience muscle weakness that eventually led to him using a wheelchair. After years of visits to specialists failed to diagnose his neurological symptoms, he enrolled in a National Institutes of Health (NIH)-funded program that studies patients with debilitating mystery diseases. Researchers...
Alison Avenell spent years collecting evidence that Yoshihiro Sato, a now-deceased nutritional researcher in Japan, was among the most prolific fraudsters known to science. After journals investigated the findings by Avenell, a clinical nutritionist at the University of Aberdeen, and her colleagues,
they retracted more than two dozen papers Sato had co-authored
. Many had...

WHO declines to label monkeypox a global threat
After 2 days of deliberation, an advisory panel convened by the World Health Organization (WHO) has concluded the monkeypox outbreak that has spread to more than 50 countries does not yet warrant the declaration of a Public Health Emergency of International Concern (PHEIC), its highest alert level. WHO currently has PHEIC declarations for polio and COVID-19, and many infectious disease...
