Recent U.S. decisions about vaccines signal bigger changes to come that could threaten the foundation of the national childhood immunization schedule.

Polar marine ecologist Marianne Falardeau investigates how Arctic ecosystems are shifting under climate change.

In 2025, the Trump administration froze or ended about 5,300 NIH and NSF research grants totaling over $5 billion in unspent funds, a decision that reshaped many fields of science.

People who use search engines develop deeper knowledge and are more invested in what they learn than those relying on AI chatbots, a study reports.

Battles between the Trump administration and academic institutions are putting important biomedical advances in limbo.

A carefully crafted figure of a goose and a woman suggests that art reflecting spiritual beliefs entered a new phase among early villagers in the Middle East.

Video from the Haíɫzaqv Nation Indigenous community shows a wolf hauling a crab trap ashore. Scientists are split on whether it counts as tool use.

Some ants kill the queens of another species and take over their colonies, but we now know at least one species gets workers to do the dirty work for them through a kind of chemical subterfuge

Newly mated parasitic queen ants invade colonies and spray their victims with a chemical irritant that provokes the workers to kill their mother.

The Trump administration’s cuts to heat research come at a time when climate change is making extreme heat waves more common and intense.

Researchers found that ancient hominids—including early humans—were exposed to lead throughout childhood, leaving chemical traces in fossil teeth. Experiments suggest this exposure may have driven genetic changes that strengthened language-related brain functions in modern humans.

Researchers have sequenced the oldest RNA ever recovered, taken from a woolly mammoth frozen for nearly 40,000 years. The RNA reveals which genes were active in its tissues, offering a rare glimpse into its biology and final moments. Surprisingly, the team also identified ancient microRNAs and rare mutations that confirm their mammoth origin. The finding shows that RNA can endure millennia—reshaping how scientists study extinct species.

Scientists uncovered Australia’s oldest known crocodile eggshells, revealing the secret lives of ancient mekosuchine crocodiles that once dominated inland ecosystems. These crocs filled surprising niches, including terrestrial stalking and possibly tree-dropping ambushes.

RNA from an exceptionally well preserved woolly mammoth gives us a window on gene activity in an animal that died nearly 40,000 years ago

Ancient RNA from Yuka, a 40,000-year-old woolly mammoth preserved in permafrost, can offer new biological insights into the Ice Age animal’s life.
