Selenium contamination of freshwater ecosystems is an ongoing environmental health problem around the world. A naturally occurring trace element, selenium levels are high in some geologic formations like sedimentary shales that form much of the bedrock in the Western United States. Soils derived from this bedrock, and weathering of shale outcrops, can contribute high levels of selenium to...
Whether it's a "Zoombomb" filled with racial slurs, a racist meme that pops up in a Facebook timeline, or a hate-filled comment on an Instagram post, social media has the power to bring out the worst of the worst.
Using a 25-year record of satellite observations over the Getz region in West Antarctica, scientists have discovered that the pace at which glaciers flow towards the ocean is accelerating. This new research, which includes data from the Copernicus Sentinel-1 mission and ESA's CryoSat mission, will help determine if these glaciers could collapse in the next few decades and how this would affect...
Providing corals with cocktails of natural probiotics could enhance their tolerance to stress and reduce mortality in coral bleaching events.
Marine biologists have been able to visualize for the first time how tropical sponges and their symbiotic bacteria work together to consume and recycle organic food. The research led by Meggie Hudspith and Jasper de Goeij from the University of Amsterdam, was a collaborative project with colleagues from the Australian Universities of Sydney, Queensland and Western Australia, and the research...
Technology helps humans maintain connections, get work done, and relax after a long day. How it can best improve the lives of animals, particularly those in captivity, however, has remained an open question.
To combat climate change, shifting from fossil fuels to clean and sustainable energy sources is imperative. A popular candidate in this regard is hydrogen, an eco-friendly fuel that produces only water when used. However, the efficient methods of hydrogen production are usually not eco-friendly. The eco-friendly alternative of splitting water with sunlight to produce hydrogen is inefficient and...
A toxin produced by bacteria as a defense mechanism causes mutations in target bacteria that could help them survive, according to a study published today in eLife.
Shipping traffic can be a major source of tiny plastic particles floating in the sea, especially out in the open ocean. In a paper published in the scientific journal Environmental Science & Technology, a team of German environmental geochemists based at the University of Oldenburg's Institute of Chemistry and Biology of the Marine Environment and led by Dr. Barbara Scholz-Boettcher for the first...
University of Minnesota Medical School researchers have developed two new rapid diagnostic tests for COVID-19—one to detect COVID-19 variants and one to help differentiate with other illnesses that have COVID-19-like symptoms. The findings were recently published in the journal Bioengineering.
Multi-ethnic neighborhoods in England retain their diversity and are much more stable than such neighborhoods in the U.S., according to geographers from the U.S. and U.K. The team examined how neighborhood diversity has changed on a national scale from 1991 to 2011 using U.K. Census data.
Warming temperatures will potentially alter the climate in Alaska so profoundly later this century that the number of thunderstorms will triple, increasing the risks of widespread flash flooding, landslides, and lightning-induced wildfires, new research finds.
Researchers from the University of Illinois Chicago have discovered a new gene-editing technique that allows for the programming of sequential cuts—or edits—over time.
Fishing primarily removes larger and more active fish from populations. It thus acts as a selection factor that favors shy fish, as a recent study by the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) shows. The promotion of rather small, shy and overall harder to catch fish has consequences for the quality of the fishery and makes it difficult to accurately survey the...
The ability to turn a gene off only in a specific cell type is essential to modern life science. Thanks to the Cre-Controlled CRISPR it has just became simpler. The new method developed by researchers from the Center for Regenerative Therapies Dresden (CRTD) at TU Dresden with support from the DRESDEN-concept Genome Center (DCGC) offers a fast and easy approach for conditional gene inactivation....
A team of researchers from the Hebrew University of Jerusalem (HUJI) led by Dr. Assaf Horesh have discovered the first evidence of radio flares emitted only long after a star is destroyed by a black hole. Published in the periodical Nature Astronomy, the discovery relied upon ultra-powerful radio telescopes to study these catastrophic cosmic events in distant galaxies called Tidal Disruption...
Using viruses instead of antibiotics to tame troublesome drug-resistant bacteria is a promising strategy, known as bacteriophage or "phage therapy." Scientists at the National Institutes of Health have used two different bacteriophage viruses individually and then together to successfully treat research mice infected with multidrug-resistant Klebsiella pneumoniae sequence type 258 (ST258). The...
The way a fish swims reveals a lot about its personality, say scientists
The remarkable genetic scissors called CRISPR/Cas9, the discovery that won the 2020 Nobel Prize in Chemistry, sometimes cut in places that they are not designed to target. Though CRISPR has completely changed the pace of basic research by allowing scientists to quickly edit genetic sequences, it works so fast that it is hard for scientists to see what sometimes goes wrong and figure out how to...
New storage and information technology requires new higher performance materials. One of these materials is yttrium iron garnet, which has special magnetic properties. Thanks to a new process, it can now be transferred to any material. Developed by physicists at Martin Luther University Halle-Wittenberg (MLU), the method could advance the production of smaller, faster and more energy-efficient...
Members of the German Bundestag who belong to underrepresented groups are more active in the legislative process and, early on, typically tend to advocate more for the interests of their groups. However, a current study by the universities in Konstanz, Basel, Geneva and Stuttgart indicates that, after a few years, most of them do move on to other political fields. This is tied to the...
During glacial periods, the sea level falls, because vast quantities of water are stored in the massive inland glaciers. To date, however, computer models have been unable to reconcile sea-level height with the thickness of the glaciers. Using innovative new calculations, a team of climate researchers led by the Alfred Wegener Institute has now managed to explain this discrepancy. The study, which...
X-ray scans revolutionized medical treatments by allowing us to see inside humans without surgery.
