Monarch butterfly population moves closer to extinction

by Olga R. Rodriguez This Aug. 19, 2015, file photo, shows a monarch butterfly in Vista, Calif. The number of western monarch butterflies wintering along the California coast has plummeted to a new record low, putting the orange-and-black insects closer to extinction, researchers announced Tuesday, Jan. 19, 2021. A recent count by the Xerces Society […]

Catalysts: worth taking a closer look

Metal surfaces play a role as catalysts for many important applications – from fuel cells to the purification of car exhaust gases. However, their behaviour is decisively affected by oxygen atoms incorporated into the surface. This phenomenon has been known for a long time, but until now it has been impossible to precisely investigate the […]

Our galaxy’s supermassive black hole is closer to Earth than we thought

The supermassive black hole hiding in the center of our galaxy is much closer to Earth, about 2,000 light-years closer, than scientists thought, according to new research out of Japan.  Not only that but our solar system is moving faster than thought as it orbits this galactic center.  All this doesn’t mean you need to […]

Researchers take a closer look at the genomes of microbial communities in the human mouth

Bacteria often show very strong biogeography—some bacteria are abundant in specific locations while absent from others—leading to major questions when applying microbiology to therapeutics or probiotics: how did the bacteria […]

Earth faster, closer to black hole in new map of galaxy

Position and velocity map of the Milky Way Galaxy. Arrows show position and velocity data for the 224 objects used to model the Milky Way Galaxy. The solid black lines show the positions of the Galaxy’s spiral arms. The colors indicate groups of objects belonging the same arm. The background is a simulation image. Credit: […]

A new spin on atoms gives scientists a closer look at quantum weirdness — ScienceDaily

When atoms get extremely close, they develop intriguing interactions that could be harnessed to create new generations of computing and other technologies. These interactions in the realm of quantum physics have proven difficult to study experimentally due the basic limitations of optical microscopes. Now a team of Princeton researchers, led by Jeff Thompson, an assistant […]

Cicada-inspired waterproof surfaces closer to reality, researchers report

IMAGE: Researchers have demonstrated a new fabrication technique that allows them to replicate the nanostructures found on cicada wings that make them water- and microbe-repellent. view more  Credit: Wayne Boo, U.S. Geological Survey CHAMPAIGN, Ill. — A multidisciplinary group that studies the physical and chemical properties of insect wings has demonstrated the ability to reproduce the […]
