Published Hormones have the potential to treat liver fibrosis
(via sciencedaily.com) Original source Researchers have discovered previously unknown changes in a specific type of liver cells, potentially opening avenues for a new treatment for liver fibrosis, a potentially life-threatening condition. Currently, there are no drugs available to treat liver fibrosis.
Published More than meows: How bacteria help cats communicate
(via sciencedaily.com) Original source Many mammals, from domestic cats and dogs to giant pandas, use scent to communicate with each other. A new study shows how domestic cats send signals to each other using odors derived from families of bacteria living in their anal glands.
Published Forget social distancing: House finches become more social when sick
(via sciencedaily.com) Original source Social distancing when sick has become second nature to many of us in the past few years, but some sick animals appear to take a different approach. A new study of house finches uncovered a surprising result. Unlike other social animals who passively or actively isolate themselves when sick, this gregarious backyard bird species gravitates toward healthy flock mates when they are sick, even more so than healthy birds do.
Published Hemp cannabinoids may have evolved to deter insect pests
(via sciencedaily.com) Original source Cannabinoids, naturally occurring compounds found in hemp plants, may have evolved to deter pests from chewing on them, according to new research that showed higher cannabinoid concentrations in hemp leaves led to proportionately less damage from insect larvae.
Published How bacteria recognize viral invasion and activate immune defenses
(via sciencedaily.com) Original source Bacteria have an array of strategies to counter viral invasion, but how they first spot a stranger in their midst has long been a mystery.
Published Riddle of Kondo effect solved in ultimately thin wires
(via sciencedaily.com) Original source A research team has now directly measured the so-called Kondo effect, which governs the behavior of magnetic atoms surrounded by a sea of electrons: New observations with a scanning tunneling microscope reveal the effect in one-dimensional wires floating on graphene.
Published Surveilling wetlands for infectious bird flu -- and finding it
(via sciencedaily.com) Original source Recently, morning omelets and holiday dinners have gotten more expensive. One likely cause is bird flu, outbreaks of which led to the deaths of millions of chickens and turkeys from infection or culling in 2022, according to the U.S. Department of Agriculture, and which still demands rigorous monitoring of wild populations. Now, researchers have developed a method that detected infectious bird flu virus in wetlands frequented by waterfowl.
Published Colliding ribosomes activate RNA repair
(via sciencedaily.com) Original source Researchers discover how ribosomes contribute to the recognition and removal of RNA crosslinking damage.
Published Unexpected discovery opens bioengineering opportunities for human and plant health
(via sciencedaily.com) Original source An unexpected genetic discovery in wheat has led to opportunities for metabolic engineering of versatile compounds with potential to improve its nutritional qualities and resilience to disease.
Published Genetic discovery promises high-iron vegetables and cereals
(via sciencedaily.com) Original source A genetic breakthrough has opened new opportunities for iron-fortified vegetables and cereal crops to help address the global health issue of anemia.
Published Novel C. diff structures are required for infection, offer new therapeutic targets
(via sciencedaily.com) Original source Newly discovered iron storage 'ferrosomes' inside the bacterium C. diff -- the leading cause of hospital-acquired infections -- are important for infection in an animal model and could offer new targets for antibacterial drugs. They also represent a rare demonstration of a membrane-bound structure inside a pathogenic bacterium, upsetting the biological dogma that bacteria do not contain organelles.
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 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 Keep it secret: Cloud data storage security approach taps quantum physics
(via sciencedaily.com) Original source Distributed cloud storage is a hot topic for security researchers, and a team is now merging quantum physics with mature cryptography and storage techniques to achieve a cost-effective cloud storage solution.
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.
