For the third year in a row, Science News profiled 10 early- and mid-career innovators who are transforming their fields in “The SN 10: Scientists to watch” (SN: 10/14/17, p. 16).
The profiles left some readers inspired, intrigued and wanting to know more about these scientists’ research.
“Really enjoying these portraits, thanks, SN!” online reader Maia commented on...
Nomadic herders living on western Asia’s hilly grasslands made a couple of big moves east and west around 5,000 years ago. These were not typical, back-and-forth treks from one seasonal grazing spot to another. These people blazed new trails.
A technological revolution had transformed travel for ancient herders around that time. Of course they couldn’t make online hotel reservations....
If the universe were a soup, it would be more of a chunky minestrone than a silky-smooth tomato bisque.
Sprinkled with matter that clumps together due to the insatiable pull of gravity, the universe is a network of dense galaxy clusters and filaments — the hearty beans and vegetables of the cosmic stew. Meanwhile, relatively desolate pockets of the cosmos, known as voids, make up a thin...
It’s a rare triumph when a species comes back from the dead. A new genetic analysis has officially established what many entomologists and conservation biologists hoped was true: The Lord Howe stick insect (Dryococelus australis) lives.
Nicknamed “tree lobsters,” the dark-brown crawlers are nocturnal, flightless creatures that can grow up to 15 centimeters long. They feed on tea trees,...
The human brain is teeming with diversity. By plucking out delicate, live tissue during neurosurgery and then studying the resident cells, researchers have revealed a partial cast of neural characters that give rise to our thoughts, dreams and memories.
So far, researchers with the Allen Institute for Brain Science in Seattle have described the intricate shapes and electrical properties...
Artificial cells made from scratch in the lab could one day offer a more effective, patient-friendly diabetes treatment.
Diabetes, which affects more than 400 million people around the world, is characterized by the loss or dysfunction of insulin-making beta cells in the pancreas. For the first time researchers have created synthetic cells that mimic how natural beta cells sense blood...
Orangutans living in forested foothills on the Indonesian island of Sumatra represent a previously unknown species, researchers say.
Skeletal and genetic evidence puts these apes on a separate evolutionary trajectory from other orangutans in Sumatra (Pongo abelii) and Bornean orangutans (Pongo pygmaeus), says a team led by evolutionary anthropologist Michael Krützen of the University of...
High-energy particles from outer space have helped uncover an enigmatic void deep inside the Great Pyramid of Giza.
Using high-tech devices typically reserved for particle physics experiments, researchers peered through the thick stone of the largest pyramid in Egypt for traces of cosmic rays and spotted a previously unknown empty space. The mysterious cavity is the first major structure...
News in Brief
The asteroid collision that may have doomed the dinosaurs 66 million years ago really stank. A new analysis of gases released from vaporized rocks at the impact site in modern-day Mexico suggests that the smashup released up to three times more smelly, climate-cooling sulfur than previously believed.
The Chicxulub impact spewed about 325 billion tons of sulfur and 425 billion tons of...

The wind is helping to awaken one of Antarctica’s sleeping giants. Warm ocean waters, driven inland by winds, are undercutting an ice shelf that holds back a vast glacier from sliding into the ocean, researchers report November 1 in Science Advances.
Totten Glacier is East Antarctica’s largest glacier, with a drainage basin encompassing about 550,000 square...
