Published New deep learning AI tool helps ecologists monitor rare birds through their songs
(via sciencedaily.com) Original source Researchers have developed a new deep learning AI tool that generates life-like birdsongs to train bird identification tools, helping ecologists to monitor rare species in the wild.
Published Dangerous bee virus less deadly in at least one US forest
(via sciencedaily.com) Original source Researchers have found that the deadly deformed wing virus (DMV) in bees may have evolved to be less deadly in at least one U.S. forest. The findings could have implications for preventing or treating the virus in managed colonies, researchers said.
Published Using cosmetic ingredient for battery protection
(via sciencedaily.com) Original source A research team has devised a battery electrode protective film using biopolymers sourced from cosmetic ingredients.
Published Shark fear: Just when you thought it was safe to get back in the water...
(via sciencedaily.com) Original source It's one of the most famous taglines in film history, immortalizing sharks as ruthless predators. But beyond the horror generated by Spielberg's Jaws series, a persistent fear of sharks remains, with consequences that extend into reality.
Published Non-native species likely to continue spreading in North America, Australia and Europe
(via sciencedaily.com) Original source Naturalized species, which are not native but have established themselves in new locations, have the potential to spread even further to suitable habitats in many parts of the world, reports a new study.
Published Shedding new light on sugars, the 'dark matter' of cellular biology
(via sciencedaily.com) Original source Chemists have developed a new tool for detecting interactions between sugars and lectins, a discovery that could help in the fight against diseases like cancer.
Published Forecasting microbiomes for sustainability and health
(via sciencedaily.com) Original source Microbial communities, or microbiomes, are essential for safeguarding human and environmental health through the most widely used biotechnological process on our planet: biological wastewater treatment. However, the process itself is subject to constant changes, difficult to sustain over long periods of time and emits significant amounts of greenhouse gases.
Published How tiny hinges bend the infection-spreading spikes of a coronavirus
(via sciencedaily.com) Original source Far from being stiff and pointy, a coronavirus's infectious spikes are shaped like chicken drumsticks with the meaty part facing out, and the meaty part can tilt every which way on its slender stalk. A new study suggests that disabling those hinges could block infection.
Published A tale of two proteins: Fundamental research could make growing better crops like clockwork
(via sciencedaily.com) Original source Rhomboid-like protein 10, or RBL10, is thought to be an enzyme that degrades other proteins in the chloroplast membrane, but its function is largely unknown. Researchers are studying how RBL10 affects photosynthetic membrane lipid metabolism, an essential process in photosynthesis.
Published Hormonal contraceptives in teens may alter risk assessment, rat study suggests
(via sciencedaily.com) Original source Hormonal contraceptives taken by adolescents may influence development of the brain in a way that alters the recognition of risks, a new study in rats suggests.
Published Evolution of taste: Early sharks were able to perceive bitter substances
(via sciencedaily.com) Original source New genetic data show that humans and sharks share bitter taste receptors, even though their evolutionary pathways separated nearly 500 million years ago.
Published New discovery on how green algae count cell divisions illuminates key step needed for the evolution of multicellular life
(via sciencedaily.com) Original source An international research team has made an unexpected discovery of a biased counting mechanism used by the single-celled green alga Chlamydomonas to control cell division.
Published How marine bristle worms use a special protein to distinguish between sunlight and moonlight
(via sciencedaily.com) Original source A research team has presented its findings on the functioning of an atypical cryptochrome protein (Cry). These proteins are found in a variety of organisms, and they are often involved in light-controlled biological processes. The marine bristle worm Platynereis dumerilii, for example, employs a special Cry protein designated L-Cry to distinguish between sunlight and moonlight as well as between different moon phases. This is essential for the worms to synchronize their reproduction to the full moon phase via an inner monthly calendar, also called circalunar clock.
Published Cycle of fasting and feeding is crucial for healthy aging
(via sciencedaily.com) Original source Fasting interventions, which involve alternating periods of fasting and refeeding, are generally thought to improve health. But these interventions don't work as well in old animals. The question is: Why? By studying the short-lived killifish, researchers have shown that older fish deviate from a youthful fasting and refeeding cycle, and instead enter a state of perpetual fasting, even when ingesting food. However, the benefits of refeeding after fasting in old killifish can be restored by genetically activating a specific subunit of AMP kinase, an important sensor of cellular energy. These mutant fish experienced improved health and longevity, indicating that both fasting and refeeding are needed to confer health benefits and act through AMP kinase to do so.
Published Mysterious new moth species discovered in Europe
(via sciencedaily.com) Original source European Lepidoptera (butterflies and moths), with a currently known inventory of approximately 11,000 species, are generally considered well-researched. However, a new genus and species from the Geometrid moth family tell a different story. The moth, named Mirlatia arcuata, is one of the most remarkable discoveries in Lepidoptera of recent decades.
Published Ground-breaking discovery could pave the way for new therapies to prevent cardiovascular disease and stroke
(via sciencedaily.com) Original source Researchers have discovered the mechanism by which cholesterol in our diet is absorbed into our cells. This discovery opens up new opportunities for therapeutic intervention to control cholesterol uptake that could complement other therapies and potentially save lives.
Published Template for success: Shaping hard carbon electrodes for next-generation batteries
(via sciencedaily.com) Original source Sodium- and potassium-ion batteries are promising next-generation alternatives to the ubiquitous lithium-ion batteries (LIBs). However, their energy density still lags behind that of LIBs. To tackle this issue, researchers explored an innovative strategy to turn hard carbon into an excellent negative electrode material. Using inorganic zinc-based compounds as a template during synthesis, they prepared nanostructured hard carbon, which exhibits excellent performance in both alternative batteries.
Published Forming ice: There's a fungal protein for that
(via sciencedaily.com) Original source New research explores how proteins produced by a common fungus trigger ice nucleation at warm temperatures. The study holds potential implications for improving our understanding of how life affects precipitation and climate.
Published New study indicates C4 crops less sensitive to ozone pollution than C3 crops
(via sciencedaily.com) Original source Researchers have studied the effects of elevated O3 on five C3 crops (chickpea, rice, snap bean, soybean, wheat) and four C4 crops (sorghum, maize, Miscanthus × giganteus, switchgrass). Their findings indicate that C4 crops are much more tolerant of high O3 concentrations than C3 crops.
Published The Goldilocks Effect: Researchers establish framework for protein regulation
(via sciencedaily.com) Original source Researchers are working to understand how protein quality control works in cells.
