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...

Warmer winters could wipe out Antarctica’s only native insect

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 ( Belgica antarctica ) is...

NIH’s vaunted program for solving puzzling medical cases is running out of money

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...

‘Zombie papers’ just won’t die. Retracted papers by notorious fraudster still cited years later

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 emergency

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...

In the Balkans, researchers mobilize to protect a wild river

Five years ago, researchers from across Europe converged on a cold, fast-moving river in the highlands of Albania for a week of intensive fieldwork. Their mission: to kick off a multiyear effort to assemble a detailed ecological portrait of the Vyosa River, one of Eastern Europe’s last free-flowing waterways. They hoped to draw public attention to the river’s rich wildlife and...

Poliovirus in London sewage sparks alarm

Yesterday, declaring a “national incident” after poliovirus was detected in London sewage, public health officials in the United Kingdom asked physicians to be on alert for polio cases and urged residents to check whether they are up to date with their vaccinations for the now-rare disease. The source of the virus is still a mystery, but was likely someone from outside of the United...
