Published Ancestral mitoviruses discovered in mycorrhizal fungi
(via sciencedaily.com) Original source A new group of mitochondrial viruses confined to the arbuscular mycorrhizal fungi Glomeromycotina may represent an ancestral lineage of mitoviruses.
Published New research could help breed for less 'spooky' horses
(via sciencedaily.com) Original source Researchers are working to identify genes that influence horses' tendency to react to perceived danger.
Published Hammerhead sharks hold their breath on deep water hunts to stay warm
(via sciencedaily.com) Original source Scalloped hammerhead sharks hold their breath to keep their bodies warm during deep dives into cold water where they hunt prey such as deep sea squids. This discovery provides important new insights into the physiology and ecology of a species that serves as an important link between the deep and shallow water habitats.
Published Water warming study shows unexpected impact on fish size
(via sciencedaily.com) Original source The theory that water-breathing animals such as fish will shrink due to global warming has been called into question by a new study.
Published The bat's ability to convert energy into muscle power is affected by flight speed
(via sciencedaily.com) Original source Small bats are bad at converting energy into muscle power. Surprisingly, a new study led by Lund University in Sweden reveals that this ability increases the faster they fly.
Published Scientists develop gene silencing DNA enzyme that can target a single molecule
(via sciencedaily.com) Original source Researchers have developed a DNA enzyme -- or DNAzyme -- that can distinguish between two RNA strands inside a cell and cut the disease-associated strand while leaving the healthy strand intact. This breakthrough 'gene silencing' technology could revolutionize the development of DNAzymes for treating cancer, infectious diseases and neurological disorders.
Published Uniformity of prey can yield spider-eat-spider world
(via sciencedaily.com) Original source A limited menu of prey may weave a tangled food web by emboldening wolf spiders of multiple species to dine on each other and even cannibalize their own, says a new study.
Published T cells can activate themselves to fight tumors
(via sciencedaily.com) Original source Scientists find an auto-signaling mechanism driving the T cell anti-tumor response; findings may inspire new cancer therapeutics and biomarkers.
Published New probe aids novel findings on cell functions
(via sciencedaily.com) Original source New research shows the use of a new cellular probe helped discover new findings about certain cellular processes.
Published Elucidating the mysteries of enzyme evolution at the macromolecular level
(via sciencedaily.com) Original source Researchers have made a major breakthrough earlier this year in the field of evolutionary conservation of molecular dynamics in enzymes. Their work points to potential applications in health, including the development of new drugs to treat serious diseases such as cancer or to counter antibiotic resistance.
Published Researchers close to unleashing rapeseed's protein power for human consumption
(via sciencedaily.com) Original source Half of plant proteins in the EU come from rapeseed plants. Until now, the plant has only been used for oil and animal feed, as it is both bitter and unsafe for human consumption. In a new study, researchers have gotten closer to removing the plant's bitter substances, and in doing so, are paving the way for a new protein source to support the green transition.
Published Single approach on wild horses
(via sciencedaily.com) Original source Because contrasting societal views have created an approach that simultaneously manages horses on the range as wildlife, livestock and pets, current U.S. government programs are incapable of succeeding, according to researchers.
Published AI could run a million microbial experiments per year
(via sciencedaily.com) Original source Automation uncovers combinations of amino acids that feed two bacterial species and could tell us much more about the 90% of bacteria that humans have hardly studied. An artificial intelligence system enables robots to conduct autonomous scientific experiments -- as many as 10,000 per day -- potentially driving a drastic leap forward in the pace of discovery in areas from medicine to agriculture to environmental science.
Published Gutless marine worms on a Mediterranean diet: Animals can synthesize phytosterols
(via sciencedaily.com) Original source Phytosterols are good for your health, but humans and other animals are not able to make them themselves, only plants can. To acquire phytosterols, humans are increasingly turning to supplements, green smoothies, or a Mediterranean diet with plenty of plant-based foods. Researchers have now discovered that tiny gutless worms from the Mediterranean can synthesize phytosterols on their own. Their study provides evidence that many other animals also have the genes needed to make their own phytosterols.
Published Alternative 'fuel' for string-shaped motors in cells
(via sciencedaily.com) Original source Researchers discover a unique two-component molecular motor that uses a kind of renewable chemical energy to pull vesicles toward membrane-bound organelles.
Published Scientists discover the dynamics of an 'extra' chromosome in fruit flies
(via sciencedaily.com) Original source Most chromosomes have been around for millions of years. Now, researchers have revealed the dynamics of a new, very young chromosome in fruit flies that is similar to chromosomes that arise in humans and is associated with treatment-resistant cancer and infertility. The findings may one day lead to developing more targeted therapies for treating these conditions.
Published Vanishing glaciers threaten alpine biodiversity
(via sciencedaily.com) Original source With glaciers melting at unprecedented rates due to climate change, invertebrates that live in the cold meltwater rivers of the European Alps will face widespread habitat loss, warn researchers. Many of the species are likely to become restricted to cold habitats that will only persist higher in the mountains, and these areas are also likely to see pressures from the skiing and tourism industries or from the development of hydroelectric plants.
Published A novel stem cell adhesive using mussels
(via sciencedaily.com) Original source A team of researchers develops stem cell adhesive for arthritis treatment using mussel adhesion protein and hyaluronic acid.
Published Scientists present evidence for a billion-years arms race between viruses and their hosts
(via sciencedaily.com) Original source Researchers have proposed a new evolutionary model for the origin of a kingdom of viruses called Bamfordvirae, suggesting a billion-years evolutionary arms race between two groups within this kingdom and their hosts.
Published 'Zero plant extinction' is possible, says plant ecologist
(via sciencedaily.com) Original source Like animals, many plant species are struggling to adapt to a human-dominated planet. However, plants are often overlooked in conservation efforts, even though they are cheaper and easier to protect than animals and play a pivotal role in bolstering our food, fuel, and medical systems. A plant ecologist suggests an approach for preventing all future land plant extinctions across the globe which includes training more plant experts, building an online 'metaherbarium,' and creating 'microreserves.'
