Communication is a two-way street. Thanks to quantum mechanics, that adage applies even if you’ve got only one particle to transmit messages with.
Using a single photon, or particle of light, two people can simultaneously send information to one another, scientists report in a new pair of papers. The feat relies on a quirk of quantum mechanics — superposition, the phenomenon through...
Fishing has left a hefty footprint on Earth. Oceans cover more than two-thirds of the planet’s surface, and industrial fishing occurred across 55 percent of that ocean area in 2016, researchers report in the Feb. 23 Science. In comparison, only 34 percent of Earth’s land area is used for agriculture or grazing.
Previous efforts to quantify global fishing have relied on a hodgepodge of...
To play good defense against the next viral pandemic, it helps to know the other team’s offense. But the 263 known viruses that circulate in humans represent less than 0.1 percent of the viruses suspected to be lurking out there that could infect people, researchers report in the Feb. 23 Science.
The Global Virome Project, to be launched in 2018, aims to close that gap. The international...
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....
News in Brief
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...

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...
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, 1968Update
“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.02/21/2018 - 16:00 Paleontology, Evolution
