Bad news for Paxlovid? Coronavirus can find multiple ways to evade COVID-19 drug

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...

Pentagon UFO study led by researcher who believes in the supernatural

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?" cracked one headline. The truth was still out there. So was...

Humans tamed the microbes behind cheese, soy, and more

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...

Ancient wolves give clues to origins of dogs

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...

Scientists pinpoint new brain target for antinausea drugs

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

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...

Does warfare make societies more complex? Controversial study says yes

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

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...

Artificial intelligence could spot baby chickens in distress

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...
