Science News Video: This little bot can hitchhike, swim and swoop with ease
Robots on long survey missions need to conserve power whenever possible. What if they could just hitch a ride on whatever they’re studying? That’s the idea behind a new robot, inspired by remoras, fish that hitchhike onto other animals using an adhesive disc on top of their head.
Remoras use lamellae, slat-like bones encased in soft tissue, and spinules, rows of hard teeth-like tissue to create tight suction. In 2017, scientists created a disc inspired by these features. But the disc couldn’t suction with individual lamella, making it vulnerable to falling off.
In the new study, the researchers created a disc with redundant suctions, allowing it to attach to surfaces even if part of its disc was not fully attached.
Adding propellers on board enabled the robot to swim underwater and latch onto moving objects. The bot could also launch itself out of the water in less than half a second, scientists report this week in Science Robotics.
The researchers anticipate this robot being used in a variety of situations: from diving in the water to tag animals, to long term environmental surveys. Watch the video to see the robot tackle a variety of situations with ease.

Science News Video: Your dog’s breed doesn’t determine its personality, study suggests
A new study shows that almost none of the behaviors we associate with dog breeds—from lovable Labradors to pugnacious pit bulls—are hard-wired. Aside from a few ancient traits, environment seems to play a much larger role than pedigree.
Read the research: www.science.org/doi/10.1126/science.abk0639
When COVID-19 first emerged, many researchers were focused on its impact on the lungs. But others, including Avindra Nath, Clinical Director of the National Institute of Neurological Disorders and Stroke, suspected COVID could also have a profound impact on the brain. Brain autopsy data from those who have died of COVID-19 have confirmed these early suspicions, revealing damaged blood vessels and inflammatory cells. Less is known about the direct impact on the brains of people with persisting symptoms weeks after an initial infection, a condition known as Long COVID. What at first seemed like a laundry list of neurological symptoms has now been focused into major categories, says Serena Spudich, a neurologist at Yale University. Watch to learn how researchers and doctors have been teasing apart how COVID impacts the brain, and testing treatments to alleviate symptoms.
The saying “out of sight, out of mind” doesn’t quite hold true for radioactive materials. Proposed permanent storage facilities for nuclear waste have encountered pushback in countries like France, Sweden, and the United States—including the latter’s famously contested Yucca Mountain site in Nevada. However, Finland has succeeded in gaining approval for a long-term nuclear waste repository, which is set to open in a few years.

Science News Video: How lizards balance keeping their tails on and peeling them off
To get out of sticky situations, some lizards detach their tails from their bodies and scurry away. Scientists have long wondered how the bones and muscles in these tails—which help with balance and movement—can sever with ease when needed, but stay firmly in place when not.
Previous studies showed the vertebrae in a lizard’s tail are ringed by muscles that fit together like plugs and sockets, with each conical “plug” covered in microscopic bumps. In a new study, researchers zoomed in on the sockets with a scanning electron microscope. They thought they would find concave notches for the bumps to fit in to—like fingers in a glove. Instead, they found only small indents—hardly the secure lock-and-release mechanism they were expecting.
But they also found that the top of each bump was dotted with holes called nanopores. To see if they played a role in the detachment, the researchers made model tails out of glass, either with or without silicone patches dotted with nanopore-like grooves. The fake tails with nanopore patches were the toughest to pry apart. Small cracks created by the pores allowed the “tail” to move flexibly without cleaving off at the wrong moment.
So how do the lizards activate their escape mechanism when needed? It all depends on how they bend and yank their tails, the researchers report today in Science. They filmed real lizards’ tails with high-speed video (above), and found that when the lizards want to detach, they bend their tails at a side angle rather than by yanking straight back. The researchers tested the motion with their silicone models, and found the patches were much easier to peel off like a sticker than to pull off like a plug. But no need to worry—most missing appendages grow back, though in the form of a cartilage “stump,” in a matter of weeks.

Science News Video: See a simulation of our galaxy’s giant black hole | Science News
Scientists created a vast library of computer simulations of Sagittarius A* (one shown) to explore the turbulent flow of hot gas that rings the black hole. That rapid flow causes the ring’s appearance to vary in brightness on timescales of minutes. Scientists compared these simulations with the newly released observations of the black hole to better understand its true properties.

Science News Video: Listen to the heart of the Milky Way | Science News
This sonification is a translation into sound of the Event Horizon Telescope’s image of the supermassive black hole Sagittarius A*. The sonification sweeps clockwise around the black hole image. Material closer to the black hole orbits faster than material farther away. Here, the faster-moving material is heard at higher frequencies. Very low tones represent material outside the black hole’s main ring. Louder volume indicates brighter spots in the image.

Science News Video: Compare mouth movements of a fetal and a baby marmoset | Science News
Ultrasounds of a marmoset in the womb show that fetal face and mouth movements (left) are similar to an infant’s contact call (right), suggesting that the fetus develops the motor skills to make its cries before it’s born and can produce sound.
