Published Sichuan Province earthquake offers lessons for landslide prediction from GNSS observations
(via sciencedaily.com) Original source Using data collected from a 2022 magnitude 6.8 earthquake in Luding County in China's Sichuan Province, researchers tested whether Global Navigation Satellite System (GNSS) observations could be used for rapid prediction of earthquake-triggered landslides.
Published Viral defense protein speeds up female stem cell production
(via sciencedaily.com) Original source A viral defense mechanism can be used to accelerate the creation of female stem cell lines in mice. The findings can boost efforts in medical research, drug testing, and regenerative therapies, particularly for women and individuals with two X chromosomes.
Published Forever chemical pollution can now be tracked
(via sciencedaily.com) Original source Researchers developed a way to fingerprint organofluorine compounds -- sometimes called 'forever chemicals' --which could help authorities trace them to their source when they end up in aquifers, waterways or soil.
Published Do smells prime our gut to fight off infection?
(via sciencedaily.com) Original source In nematodes and humans, mitochondrial stress in the nervous system initiates a whole-body response that is most pronounced in the gut. A recent study showed that in nematodes, the odor of a pathogen triggers the nervous system to broadcast this response to the rest of the organism, prepping mitochondria in intestinal cells to fight a bacterial infection. Humans, too, may be able to sense pathogenic odors that prepare the gut for an infection.
Published Cocaine discovery could pave way for treatment for substance abuse
(via sciencedaily.com) Original source Cocaine binds to a specific transporter in the brain that is responsible for regulating dopamine levels. Researchers have studied and described the process, producing new knowledge that may bring us a step closer to designing a drug for cocaine abuse.
Published Bacterial gut diversity improves the athletic performance of racehorses
(via sciencedaily.com) Original source The composition of gut bacteria of Thoroughbred racehorses at one-month-old can predict their future athletic performance, according to a new study. Foals with lower bacterial diversity at 28 days old also had a significantly increased risk of respiratory disease later in life.
Published Water delivered to the mantle by aluminum enriched hydrated slabs?
(via sciencedaily.com) Original source Researchers found a notable effect of aluminum on the sound velocities of superhydrous phase B, a dense hydrous magnesium silicate and potential host of water in the deep Earth. Their results suggest that aluminous phase B could explain seismic velocity anomalies in the Earth's mantle transition region and uppermost lower mantle.
Published Scientists uncover hidden forces causing continents to rise
(via sciencedaily.com) Original source Scientists have answered one of the most puzzling questions in plate tectonics: how and why 'stable' parts of continents gradually rise to form some of the planet's greatest topographic features.
Published Nasal microbiome: Depriving multi-resistant 'bugs' of iron
(via sciencedaily.com) Original source Whether dangerous staphylococci survive in the nose depends on what other bacteria are present -- and how they obtain iron.
Published Elephants on the move: Mapping connections across African landscapes
(via sciencedaily.com) Original source Elephant conservation is a major priority in southern Africa, but habitat loss and urbanization mean the far-ranging pachyderms are increasingly restricted to protected areas like game reserves. The risk? Contained populations could become genetically isolated over time, making elephants more vulnerable to disease and environmental change.
Published Advanced chelators offer efficient and eco-friendly rare earth element recovery
(via sciencedaily.com) Original source The world is going to need a lot of weird metals in the coming years, according to chemistry professor. But he isn't talking about lithium, cobalt or even beryllium. He's interested in dysprosium, which is so hidden in the periodic table that you'd be forgiven for thinking he made it up.
Published The race to discover biodiversity: 11 new marine species and a new platform for rapid species description
(via sciencedaily.com) Original source A new paper describes a ground-breaking experiment that united 25 independent taxonomists from 10 countries. The initiative boasts the discovery of 11 new marine species from all over the globe, occurring at depths from 5.2 to 7081 meters. It also represents a significant step forward in accelerating the pace at which new marine species are described and published.
Published Ketogenic Diet may reduce friendly gut bacteria and raise cholesterol levels
(via sciencedaily.com) Original source A study reveals that ketogenic low-carbohydrate diets can increase cholesterol levels and reduce beneficial gut bacteria, specifically Bifidobacterium.
Published Carvings at ancient monument may be world's oldest calendars
(via sciencedaily.com) Original source Markings on a stone pillar at a 12,000 year-old archaeological site in Turkey likely represent the world's oldest solar calendar, created as a memorial to a devastating comet strike, experts suggest.
Published Antarctic-wide survey of plant life to aid conservation efforts
(via sciencedaily.com) Original source The first continent-wide mapping study of plant life across Antarctica reveals growth in previously uncharted areas and is set to inform conservation measures across the region. The satellite survey of mosses, lichens and algae across the continent will form a baseline for monitoring how Antarctica's vegetation responds to climate change.
Published Study revisits Texas seismic activity occurring before 2017, confirming connection to wastewater injection
(via sciencedaily.com) Original source A new study by seismologists reexamines earthquakes in the Permian Basin that occurred before 2017 against the real-time data collected from earthquakes taking place after 2020. Results confirm that the seismicity occurring from 2009-2017 was causally linked to the underground injection of wastewater that is a byproduct of oil and gas extraction.
Published Greenland fossil discovery reveals increased risk of sea-level catastrophe
(via sciencedaily.com) Original source Seeds, twigs, and insect parts found under two miles of ice confirm Greenland's ice sheet melted in the recent past, the first direct evidence that the center -- not just the edges -- of the two-mile-deep ice melted away in the recent geological past. The new research indicates that the giant ice sheet is more fragile than scientists had realized until the last few years -- and reveals increased risk of sea-level catastrophe in a warmer future.
Published Study analyzes potato-pathogen 'arms race' after Irish famine
(via sciencedaily.com) Original source Researchers reveal more about the tit-for-tat evolutionary changes occurring in both potato plants and the pathogen that caused the 1840s Irish potato famine.
Published Seismic detectors measure soil moisture using traffic noise
(via sciencedaily.com) Original source Using state of the art techniques, researchers use vibrations from traffic to measure underground soil moisture.
Published Why virus causing cold sores does not spread to devastating brain infection
(via sciencedaily.com) Original source A previously unknown defence mechanism in the brain prevents herpesvirus from infecting the brain's nerve cells.
