| Athletes warned against potential dangers of natural supplements Posted: 26 Jan 2022 04:53 PM PST Nutritional supplements taken to boost athletic performance can pose risks to the heart, according to a recent statement. |
| Ground-breaking study reveals dynamics of DNA replication ‘licensing’ Posted: 26 Jan 2022 01:55 PM PST A new study has illuminated an important process that occurs during cell division and is a likely source of DNA damage under some circumstances, including cancer. |
| Fossil snail shells offer new tool for analyzing ancient ocean chemistry Posted: 26 Jan 2022 01:55 PM PST A collection of fossil shells from marine snails and clams is challenging a theory that says the world's deadliest mass extinction was accompanied by severe ocean acidification. The study is the first to use shells from fossilized mollusks to investigate ocean chemistry, demonstrating a new tool that scientists can use to study the conditions of the planet's deep past. |
| Ancient ice reveals mysterious solar storm Posted: 26 Jan 2022 11:42 AM PST Through analysis of ice cores from Greenland and Antarctica, a research team has found evidence of an extreme solar storm that occurred about 9,200 years ago. What puzzles the researchers is that the storm took place during one of the sun's more quiet phases -- during which it is generally believed our planet is less exposed to such events. |
| Updrafts crucial: Clouds in the southern hemisphere more precisely understood Posted: 26 Jan 2022 11:41 AM PST Clouds in the southern hemisphere reflect more sunlight than those in the northern hemisphere. The reason is a more frequent occurrence of liquid water droplets, which results from an interplay between updrafts and a cleaner environment. |
| Scientists use GPS to track baboon troop's movement in urban spaces for the first time Posted: 26 Jan 2022 11:41 AM PST In a unique study, researchers have used GPS collars to study the collective behaviour of a troop of baboons living on the outskirts of the City of Cape Town. |
| 23,000 years ago, humans in Israel enjoyed a new bounty of food options Posted: 26 Jan 2022 11:40 AM PST As climate shifted 23,000 years ago, humans in Israel experienced a new abundance of food, according to a new study. |
| Suitable growing regions for coffee, cashews, and avocados predicted to shift as Earth warms Posted: 26 Jan 2022 11:40 AM PST A new analysis predicts that, as climate change progresses, the most suitable regions for growing coffee arabica, cashews, and avocados will decline in some of the main countries that produce these crops. |
| Scientists regrow frog's lost leg Posted: 26 Jan 2022 11:40 AM PST Scientists have triggered long-term growth of legs in adult frogs, which are naturally unable to regenerate limbs. The frogs regrew a lost leg over months, triggered by just 24 hour exposure to a five-drug cocktail held under a bioreactor. The new legs were functional enough to enable sensation and locomotion. |
| Screening study IDs inhibitor of key COVID virus enzyme Posted: 26 Jan 2022 10:31 AM PST A study reports the discovery of a molecule with significant potential to disable the COVID-19 virus. The molecule was identified using high-throughput virtual screening -- a search through a library of 6.5 million in-stock compounds that could quickly be scaled up for drug production using some of the nation's most powerful supercomputers and other research tools. |
| Song sparrows shuffle and repeat to keep their audience listening Posted: 26 Jan 2022 09:24 AM PST Biologists have found an animal for the first time that communicates with the complexity of human language: song sparrows. According to a new study, male song sparrows memorize a 30-minute long playlist of their recently belted tunes and use that information to curate both their current playlist and the next one. The findings suggest that song sparrows deliberately shuffle and repeat their songs possibly to keep a female's attention. |
| Microscopic inner ear structures reveal why major groups of bats echolocate differently Posted: 26 Jan 2022 09:24 AM PST A new article compares the inner ear structures of the two main groups of bats. By examining the microscopic inner ears of bats from 19 of the 21 known bat families, the researchers were able to show that the presence of extra neurons and specialized ear structures align with a split in bat evolution revealed by DNA. |
| 'Smart saddle' could help equestrians hit their stride Posted: 26 Jan 2022 06:05 AM PST Researchers have developed a prototype 'smart saddle' that could help equestrians improve their biomechanics. Moreover, the self-powered saddle can alert others when a rider takes a fall. |
| Posted: 26 Jan 2022 06:05 AM PST Strict COVID-19 lockdown policies such as workplace closures in European cities reduced levels of air pollution and the number of associated deaths, according to new estimates. |
| Urban greening 'not a panacea' for dealing with extreme weather Posted: 26 Jan 2022 06:05 AM PST Urban greening is unlikely to provide a single fix for tackling extreme weather events brought on by climate change, scientists have suggested. |
| Cleaning your car may not protect you from this carcinogen, study finds Posted: 26 Jan 2022 06:05 AM PST It is unlikely that a cancer-causing chemical inside your car, TDCIPP, can be dusted or wiped way, according to new research. |
| Posted: 25 Jan 2022 08:26 AM PST Researchers have developed a framework that solves the challenge of bridging experimental and computer sciences to better predict peptide structures. |
| Getting hydrogen out of banana peels Posted: 25 Jan 2022 06:30 AM PST Scientists have developed a way to maximize hydrogen yields from biowaste, within few milliseconds. The method uses rapid photo-pyrolysis to produce hydrogen gas and solid conductive carbon from banana peels. |
