To understand the human brain, take note of the rare, the strange and the downright spooky. That’s the premise of two new books, Unthinkable by science writer Helen Thomson and The Disordered Mind by neuroscientist Eric R. Kandel. Both books describe people with minds that don’t work the same way as everyone else’s. These are […]
Some snippets of RNA can be a real pain. A microRNA called miR-30c-5p contributes to nerve pain in rats and people, a new study finds. A different microRNA, miR-711, interacts with a well-known itch-inducing protein to cause itching, a second study concludes. Together, the research highlights the important role that the small pieces of genetic […]
Landing sites on the asteroid Ryugu for the Hayabusa2 spacecraft and its hitchhiking landers have been picked out, scientists with Japan’s Aerospace Exploration Agency announced in a news conference on August 23. Hayabusa2 arrived at the 1,000-meter-wide asteroid on June 27, and has been scanning the surface since. More than 100 mission team members met […]
A firefly’s blinking behind is more than just a pretty summer sight. It’s known that fireflies flash to attract mates (SN Online: 8/12/15) — but the twinkles may serve another purpose as well. Jesse Barber, a biologist at Boise State University, had a hunch that the lights also warn off potential nighttime predators. He wasn’t […]
The sleepy sun turns out to be a factory of extremely energetic light. Scientists have discovered that the sun puts out more of this light, called high-energy gamma rays, overall than predicted. But what’s really weird is that the rays with the highest energies appear when the star is supposed to be at its most […]
A new material that converts light into heat could be laminated onto airplanes, wind turbines, rooftops and offshore oil platforms to help combat ice buildup. This deicer, called a photothermal trap, has three layers: a top coating of a ceramic-metal mix that turns incoming light into thermal energy, a middle layer of aluminum that spreads […]
New images of gas churning inside an ancient starburst galaxy help explain why this galactic firecracker underwent such frenzied star formation. Using the Atacama Large Millimeter/submillimeter Array, or ALMA, researchers have taken the most detailed views of the disk of star-forming gas that permeated the galaxy COSMOS-AzTEC-1, which dates back to when the universe was […]
Obesity can affect brainpower, and a study in mice may help explain how. In the brains of obese mice, rogue immune cells chomp nerve cell connections that are important for learning and memory, scientists report September 10 in the Journal of Neuroscience. Drugs that stop this synapse destruction may ultimately prove useful for protecting the […]
I’m relatively new to Oregon, but one of the ways I know I’m starting to settle in is my ability to recognize marijuana shops. Some are easy. But others, with names like The Agrestic and Mr. Nice Guy, are a little trickier to identify for someone who hasn’t spent much time in a state that […]
NOORDWIJK, THE NETHERLANDS — Life might arise in the darkest of places: the moon of a planet wandering the galaxy without a star. The gravitational tug-of-war between a moon and its planet can keep certain satellites toasty enough for liquid water to exist there — a condition widely considered crucial for life. Now computer simulations […]
