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.

Genetic, isotopic, and forensic evidence has conclusively identified the remains of Duke Béla of Macsó and uncovered remarkable details about his life, ancestry, and violent death. The study reveals a young nobleman with Scandinavian-Rurik roots who was killed in a coordinated, emotionally charged attack in 1272.

The drug enlicitide reduced cholesterol for adults with high levels due to an inherited disorder and may also work for a broader population.

An analysis of mining plumes in the Pacific Ocean reveals they kick up particles sized similarly to the more nutritious tidbits that plankton eat.

Interruptions, to-do lists, lack of autonomy — “time poverty” depends more on perceived shortages of time than actual ones, recent research suggests.

Footprints preserved on ancient dunes show Neanderthals actively navigating, hunting, and living along Portugal’s coastline. Their behavior and diet suggest a far more adaptable and socially complex population than once assumed.

Researchers discovered that living horsetails act like natural distillation towers, producing bizarre oxygen isotope signatures more extreme than anything previously recorded on Earth—sometimes resembling meteorite water. By tracing these isotopic shifts from the plant base to its tip, scientists unlocked a new way to decode ancient humidity and climate, using both modern plants and fossilized phytoliths that preserve isotopic clues for millions of years.
