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 Previously unknown luminescence revealed in ten deep sea species and an order of sea cucumbers
(via sciencedaily.com) Original source Researchers present evidence of previously unknown luminosity in 10 deep-sea species, suggesting underestimated diversity. These new discoveries include a member of the order Molpadia, which was previously thought not to be luminescent. The authors stress the importance of considering the ecological role of bioluminesence and the need for conservation.
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 Geese 'keep calm and carry on' after deaths in the flock
(via sciencedaily.com) Original source Canada geese strengthen existing friendships and forge a few new connections after losing close associates from their flock, new research shows.
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 Some of today's earthquakes may be aftershocks from quakes in the 1800s
(via sciencedaily.com) Original source In the 1800s, some of the strongest earthquakes in recorded U.S. history struck North America's continental interior. Almost two centuries later, the central and eastern United States may still be experiencing aftershocks from those events, a new study finds.
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 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.
