• Chimpanzees and bonobos have human-like friend circles, study finds

  Great apes appear to build friendships much like humans do. By studying grooming behavior, researchers discovered that chimpanzees and bonobos form close inner circles along with wider networks of weaker social connections. Chimpanzees focus on a few trusted partners and become more selective with age, while bonobos maintain a more egalitarian social style.

• New solar desalination breakthrough makes fresh water without toxic brine

  Scientists have developed a solar desalination system that turns seawater into drinking water without creating environmentally damaging brine. Special laser-textured metal panels use sunlight to evaporate water while automatically moving salt deposits away from the working surface, preventing clogging. The process was successfully tested with water from three oceans and can recover nearly all salts as solids. Those leftover materials could even become a source of valuable lithium for batteries.

• The ocean's health may depend on a tiny microbe inside fish

  A surprising new discovery suggests that tiny microbes living inside fish may be helping shape the chemistry of the world’s oceans. Scientists found evidence that bacteria in the guts of marine fish work alongside their hosts to produce calcium carbonate, a mineral that plays an important role in ocean health and carbon storage. For years, researchers believed fish handled this process on their own, but the new findings point to a hidden partnership between fish and microbes.

• Ancient DNA reveals how women helped transform prehistoric Europe

  New DNA evidence shows that Europe’s hunter-gatherers and early farmers interacted far more closely than previously thought, with women likely playing a crucial role in spreading farming across northwestern Europe. Centuries later, the arrival of Bell Beaker migrants triggered another sweeping population transformation that extended all the way to Britain.

• This bizarre crocodile relative from the Triassic looked like an ostrich dinosaur

  Scientists have discovered Labrujasuchus expectatus, a bizarre crocodile relative that looked more like an ostrich-like dinosaur than anything resembling a modern crocodile. It walked on two legs, had tiny arms, and sported a toothless beak—an unexpected combination for a member of the crocodile lineage.
