| Glass frogs living near roaring waterfalls wave hello to attract mates Posted: 15 Jan 2021 12:53 PM PST A conservationist has discovered that the glass frog Sachatamia orejuela can be added to the list of species that make use of visual cues in response to their acoustic environments. This is the first time a member of the glass frog family (Centrolenidae) has been observed using visual communication in this manner. |
| Conductive nature in crystal structures revealed at magnification of 10 million times Posted: 15 Jan 2021 12:53 PM PST In groundbreaking materials research, a team has made a discovery that blends the best of two sought-after qualities for touchscreens and smart windows -- transparency and conductivity. |
| X-Rays surrounding 'Magnificent 7' may be traces of sought-after particle Posted: 15 Jan 2021 08:03 AM PST Theoretical physicists suggest that never-before-observed particles called axions may be the source of unexplained, high-energy X-ray emissions surrounding a group of neutron stars. |
| Researchers rewind the clock to calculate age and site of supernova blast Posted: 15 Jan 2021 08:03 AM PST Astronomers are winding back the clock on the expanding remains of a nearby, exploded star. By using NASA's Hubble Space Telescope, they retraced the speedy shrapnel from the blast to calculate a more accurate estimate of the location and time of the stellar detonation. |
| Snakes evolve a magnetic way to be resistant to venom Posted: 15 Jan 2021 06:13 AM PST Certain snakes have evolved a unique genetic trick to avoid being eaten by venomous snakes, according to new research. The technique works in a manner similar to the way two sides of a magnet repel each other. |
| Guppies have varying levels of self-control Posted: 15 Jan 2021 06:13 AM PST Just like humans trying to stick to New Year's resolutions, guppies have varying levels of self-control, a new study shows. |
| Astronomers document the rise and fall of a rarely observed stellar dance Posted: 14 Jan 2021 03:06 PM PST Astronomers have catalogued 126 years of changes to HS Hydra, a rare evolving eclipsing binary star system. Analyzing observations from astro-photographic plates in the late 1800s to TESS observations in 2019, they show that the two stars in HS Hydra began to eclipse each other around a century ago, peaking in the 1960s. The degree of eclipsing then plummeted over the course of just a half century, and will cease around February 2021. |
| Scholars link diet, dentition, and linguistics Posted: 14 Jan 2021 03:06 PM PST Anthropologists used a novel data analysis of thousands of languages, in addition to studying a unique subset of celebrities, to reveal how a soft food diet -- contrasted with the diet of hunter-gatherers -- is restructuring dentition and changing how people speak. |
| How insects activate muscles to adapt to limbs removed Posted: 14 Jan 2021 01:39 PM PST Adaptability explains why insects spread so widely and why they are the most abundant animal group on earth. Insects exhibit resilient and flexible locomotion, even with drastic changes in their body structure such as losing a limb. |
