Strange brains offer a glimpse into the mind

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 […]

Tiny bits of RNA can trigger pain and itchiness

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 […]

Here’s where the Hayabusa2 spacecraft will land on the asteroid Ryugu

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 […]

There’s method in a firefly’s flashes

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 […]

Strange gamma rays from the sun may help decipher its magnetic fields

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 harnesses light to deice surfaces

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 reveal how an ancient monster galaxy fueled furious star formation

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 […]

How obesity may harm memory and learning

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 […]

Mathematicians have finally discovered an elusive ‘einstein’ tile

A 13-sided shape known as “the hat” has mathematicians tipping their caps. It’s the first true example of an “einstein,” a single shape that forms a special tiling of a plane: Like bathroom floor tile, it can cover an entire surface with no gaps or overlaps but only with a pattern that never repeats. “Everybody […]

These transparent fish turn rainbow with white light. Now, we know why

The ghost catfish transforms from glassy to glam when white light passes through its mostly transparent body. Now, scientists know why. The fish’s iridescence comes from light bending as it travels through microscopic striped structures in the animal’s muscles, researchers report March 13 in the Proceedings of the National Academy of Sciences. Many fishes with […]
