Beetle keeps rivals off scent of food buried for offspring
This November 2020 photo provided by Dr. Vanessa R. Lane shows a Nicrophorus orbicollis beetle in Georgia. Burying beetles scout for a dead mouse or bird, dig a hole and bury it, pluck its fur or feathers, roll its flesh into a ball and cover it in goop—all to feed their future offspring. Now scientists […]
Light from supernova blast reached Earth 1,700 years ago — ScienceDaily
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. The victim is a star that exploded long ago in the […]

Nations failing to fund climate adaptation: UN
Adaptation—reducing the fall out among communities and increasing their capacity to deal with climate-related disasters such as floods and drought—is a key pillar of the landmark 2015 accord The world is falling short of promises made under the Paris climate deal to help the most vulnerable nations deal with the increasingly devastating impacts of climate […]
Scientists reveal mechanism that causes irritable bowel syndrome — ScienceDaily
KU Leuven researchers have identified the biological mechanism that explains why some people experience abdominal pain when they eat certain foods. The finding paves the way for more efficient treatment of irritable bowel syndrome and other food intolerances. The study, carried out in mice and humans, was published in Nature. Up to 20% of the […]

Disfunction of these lead to severe diseases, […]
NASA test of mega Moon rocket engines cut short
NASA said the ‘hot-fire’ test of the RS-25 engines that will power the Artemis lunar missions shut down prematurely NASA conducted a test firing of the engines for its giant Space Launch System (SLS) lunar rocket on Saturday but they shut down earlier than planned, the space agency said. The “hot-fire” test at the Stennis […]
One small alcoholic drink a day is linked to an increased risk of atrial fibrillation — ScienceDaily
A study of nearly 108,000 people has found that people who regularly drink a modest amount of alcohol are at increased risk of atrial fibrillation, a condition where the heart beats in an abnormal rhythm. The study, published today (Wednesday) in the European Heart Journal [1], found that, compared to drinking no alcohol at all, […]
