Ancient footprints in Kenya reveal that eight Paranthropus boisei may have traveled together 1.4 million years ago, with some individuals reaching surprisingly large, human-like body sizes. The tracks offer a rare glimpse of their social behavior and ...

Physicists have mathematically captured a bizarre "spacetime crystal" that can either dissolve or collapse into a microscopic black hole after only a tiny change in energy. Their breakthrough came from an unusual trick involving infinitely many ...

Adults aged 40 and older performed about 12% faster on a test of executive function after using a HEPA air purifier at home for one month. The findings suggest that cleaner indoor air could offer a simple way to help protect the brain from the ...

Hundreds of previously overlooked seismic events have been detected beneath Antarctica, including 245 near the marine edge of the Thwaites Glacier. Many appear to be glacial earthquakes caused when huge icebergs break off, capsize, and collide with . ...

Mars has a hidden temperature divide, with its southern interior potentially hundreds of degrees hotter than the north and partially molten. The discovery could help explain several long-standing Martian mysteries, including unusual magnetism, ...

Scientists have cracked a long-standing chemistry problem, creating nanocrystals from tough metal nitrides that were previously extremely difficult to produce at this scale. The breakthrough could turn familiar materials used in LEDs, implants, and . ...

Scientists have discovered seven new species of Madagascar's elusive diamond frogs, using DNA from modern and century-old museum specimens to solve a long-running biological puzzle. The findings reveal surprising hidden diversity and could help ...

Weapons buried with ancient Egyptian princesses may have been more than ceremonial decorations. Researchers studying royal mummies from Dahshur found bone changes consistent with years of archery and other strenuous weapon use. Several women also ...

Researchers have produced a form of Spirulina containing biologically active vitamin B12 at levels comparable to beef. By carefully controlling the light used to grow the algae, they overcame a major problem with conventional Spirulina, which mainly ...

The Juan de Fuca plate beneath northern Oregon appears to be shallower than previously estimated, potentially making shaking from a future Cascadia megathrust earthquake significantly stronger. Scientists also found a deep basin beneath Tillamook ...
