Two partial skeletons unearthed in northeastern China have dashed the record for the oldest avian relatives of today's birds.
The remains belonged to a species, Archaeornithura meemannae, that lived 130.7 million years ago — about 6 million years earlier than the previous record holders. Fossil hunters discovered bones of the hummingbird-sized creatures embedded in siltstone...
A century from now, when biologists are playing games of clones and engineers are playing games of drones, physicists will still pledge their loyalty to the Kingdoms of Substance and Force.
Physicists know the subjects of these kingdoms as fermions and bosons. Fermions are the fundamental particles of matter; bosons transmit forces that govern the behavior of the matter particles. The...
The app uses data from the Dawn spacecraft, which orbited the asteroid from July 2011 to September 2012. Users can overlay maps of geology,...
Stretchy nerves help some whales stuff their mouths with fish.
Rorqual whales, which include the behemoth blue whale and the fin whale, have nerves in their tongues and mouths that stretch and recoil like rubber bands,...
A mouse’s optic nerve glows in a rainbow of colors in the micrograph above.
By tweaking an enzyme borrowed from a bacterium, researchers have taken a step closer to creating blood that is safe for transfusing to all people, regardless of their blood type — A, B, AB or O.
Compared with the unaltered enzyme, designated Sp3GH98, the engineered version is 170 times faster at chopping apart certain sugar-based markers found on blood cells,...
Gene therapy for a rare form of inherited blindness improves sight temporarily but can’t yet save vision cells from dying.
Light-gathering rod and cone cells continued to die in the retinas of three people despite gene therapy to correct Leber congenital amaurosis, researchers report online May 3 in the New England Journal of...

The Turing test features prominently in Alex Garland’s new film Ex Machina, but this is no meditation on computer science. It’s not even, ultimately, about artificial intelligence. The movie instead explores humans: the Frankenstein-like hubris involved in creating artificial beings; the power relationships between employee and boss, parent...
Like cannonballs slamming into stained glass, high-energy particles can shatter the delicate tendrils that connect nerve cells, a study on mice finds. This neural destruction left mice with memory and learning problems, a finding that has implications for intrepid space explorers.
The result is “worrisome, very worrisome,” says neuroscientist M. Kerry O’Banion of the University of...
