    Cave art suggests Neandertals were ancient humans’ mental equals

    Neandertals drew on cave walls and made personal ornaments long before encountering Homo sapiens, two new studies find. These discoveries paint bulky, jut-jawed Neandertals as the mental equals of ancient humans, scientists say.

    Rock art depicting abstract shapes and hand stencils in three Spanish caves dates back to at least 64,800 years ago, researchers report in the Feb. 23 Science....

    The last wild horses aren’t truly wild

    When it comes to wild claims, hold your horses.

    Free-roaming Przewalski’s horses of Central Asia are often called the last of the wild horses, the only living equines never domesticated. But a new genetic analysis of ancient horse bones suggests that these horses have a tamed ancestor after all, making them feral rather than wild.

    The findings also debunk the idea that these...

    Mission: Mars

    The possibility that human visitors could carry Earth-based microbes to the Red Planet has roiled the Mars research community, Lisa Grossman reported in “How to keep humans from ruining the search for life on Mars” (SN: 1/20/18, p. 22).

    Reader Bruce Merchant speculated that Mars would need a protective global magnetic field to sustain a life-friendly environment. But...

  • 50 years ago, early organ transplants brought triumph and tragedy

    Kidneys lead the field

    While the drama of human heart transplants has grasped the public interest, kidney transplants are ahead in the field…. Although only three little girls are now surviving liver transplants, the liver is a promising field for replacement…. The donor, of course, must be dead; no one can live without his liver. — Science News, March 2, 1968

    New fossils are redefining what makes a dinosaur

    “There’s a very faint dimple here,” Sterling Nesbitt says, holding up a palm-sized fossil to the light. The fossil, a pelvic bone, belonged to a creature called Teleocrater rhadinus. The slender, 2-meter-long reptile ran on all fours and lived 245 million years ago, about 10 million to 15 million years before scientists think dinosaurs first appeared.

    Nesbitt, a paleontologist at...

    An amateur astronomer caught a supernova explosion on camera

    An amateur astronomer caught a supernova on camera during the explosion’s earliest moments, giving physicists a glimpse of a long-sought phase of stellar death.

    Víctor Buso spotted the supernova from his rooftop observatory in Rosario, Argentina, on September 20, 2016, when he aimed his telescope straight overhead at spiral galaxy NGC 613 to test a new camera. To avoid letting in too...

    A new study eases fears of a link between autism and prenatal ultrasounds

    Ultrasounds during pregnancy can be lots of fun, offering peeks at the baby-to-be. But ultrasounds aren’t just a way to get Facebook fodder. They are medical procedures that involve sound waves, technology that could, in theory, affect a growing fetus.

    With that concern in mind, some researchers have wondered if the rising rates of autism diagnoses could have anything to do with the...

    A fake organ mimics what happens in the blink of an eye

    AUSTIN, Texas — A new artificial organ gives a new meaning to the phrase “making eyes.”

    For the first time, researchers used human cells to build a model of the surface of the eye that’s equipped with a fake eyelid that mimics blinking. This synthetic eye could be used to study and test treatments for eye diseases, researchers reported February 16 in a news conference at the annual...
