Published Phage-derived enzyme targets E. faecalis biofilms to mitigate acute graft-versus-host disease
(via sciencedaily.com) Original source Acute graft-versus-host disease occurs when donor immune cells attack the recipient's tissues after an allogeneic hematopoietic stem cell transplantation (allo-HCT). Researchers recently identified a bacteriophage-derived enzyme called endolysin capable of targeting biofilms formed by Enterococcus faecalis. Their findings offer hope for tailored interventions in allo-HCT.
Published Discovery could help reduce adverse side effects of popular next-generation obesity medications
(via sciencedaily.com) Original source By teasing apart the therapeutic benefits from the adverse effects of new generation obesity medications, researchers found a population of neurons in the brain that controls food intake without causing nausea in an animal model.
Published Big gain in battle against harmful bacteria
(via sciencedaily.com) Original source An unexpected find has enabled important progress to be made in the battle against harmful bacteria.
Published The plague may have caused the downfall of the Stone Age farmers
(via sciencedaily.com) Original source Ancient DNA from bones and teeth hints at a role of the plague in Stone Age population collapse. Contrary to previous beliefs, the plague may have diminished Europe's populations long before the major plague outbreaks of the Middle Ages, new research shows.
Published BESSY II shows how solid-state batteries degrade
(via sciencedaily.com) Original source Solid-state batteries have several advantages: they can store more energy and are safer than batteries with liquid electrolytes. However, they do not last as long and their capacity decreases with each charge cycle. But it doesn't have to stay that way: Researchers are already on the trail of the causes.
Published Could high-temperature single crystals enable electric vehicles capable of traveling up to one million kilometers?
(via sciencedaily.com) Original source Researchers unveil a microstructure design guide to enhance the durability of lithium secondary batteries.
Published New one-step method to make multiple edits to a cell's genome
(via sciencedaily.com) Original source A team of scientists have developed a new method that enables them to make precise edits in multiple locations within a cell -- all at once. Using molecules called retrons, they created a tool that can efficiently modify DNA in bacteria, yeast, and human cells.
Published A gut microbe could hold a key to help people benefit from healthy foods
(via sciencedaily.com) Original source In a study involving 50,000+ individuals from around the world, higher gut levels of Blastocystis, a single-celled organism commonly found in the digestive system, were linked to more favorable indicators of health.
Published Ancient dingo DNA shows modern dingoes share little ancestry with modern dog breeds
(via sciencedaily.com) Original source A study of ancient dingo DNA revealed that the distribution of modern dingoes across Australia, including those on K'gari (formerly Fraser Island), pre-dates European colonization and interventions like the dingo-proof fence.
Published New bio-based tool quickly detects concerning coronavirus variants
(via sciencedaily.com) Original source Researchers have developed a bioelectric device that can detect and classify new variants of coronavirus to identify those that are most harmful. It has the potential to do the same with other viruses, as well.
Published Genomic data integration improves prediction accuracy of apple fruit traits
(via sciencedaily.com) Original source Genotyping techniques can be used to select fruit trees with desired traits at the seedling stage, increasing the efficiency of fruit tree breeding. However, so far, there are multiple different genotyping systems, each generating distinct datasets. In a recent study, Japanese scientists revealed that integrating genomic data obtained with different genotyping systems can effectively combine with historical data, leveraging the accuracy of genomic predictions.
Published Visualizing short-lived intermediate compounds produced during chemical reactions
(via sciencedaily.com) Original source Immobilizing small synthetic molecules inside protein crystals proves to be a promising avenue for studying intermediate compounds formed during chemical reactions, scientists report. By integrating this method with time-resolved serial femtosecond crystallography, they successfully visualized reaction dynamics and rapid structural changes occurring within reaction centers immobilized inside protein crystals. This innovative strategy holds significant potential for the intelligent design of drugs, catalysts, and functional materials.
Published GeneMAP discovery platform will help define functions for 'orphan' metabolic proteins
(via sciencedaily.com) Original source Researchers have developed a discovery platform to probe the function of genes involved in metabolism -- the sum of all life-sustaining chemical reactions. The investigators used the new platform, called GeneMAP (Gene-Metabolite Association Prediction), to identify a gene necessary for mitochondrial choline transport.
Published Innovative battery design: More energy and less environmental impact
(via sciencedaily.com) Original source A new electrolyte design for lithium metal batteries could significantly boost the range of electric vehicles. Researchers have radically reduced the amount of environmentally harmful fluorine required to stabilize these batteries.
Published Not so selfish after all: Viruses use freeloading genes as weapons
(via sciencedaily.com) Original source Certain pieces of DNA have been labeled as 'selfish genetic elements' due to notions that they don't contribute to a host organism's survival. Instead, researchers have now discovered that these elements have been weaponized and play a crucial role by cutting off a competitor's ability to reproduce.
Published Scientists map how deadly bacteria evolved to become epidemic
(via sciencedaily.com) Original source Pseudomonas aeruginosa -- an environmental bacteria that can cause devastating multidrug-resistant infections, particularly in people with underlying lung conditions -- evolved rapidly and then spread globally over the last 200 years, probably driven by changes in human behavior, a new study has found.
Published Never-before-seen view of gene transcription captured
(via sciencedaily.com) Original source New tech reveals findings that address long-standing theories about how bacteria begin the process of making RNA from DNA.
Published Do genes-in-pieces code for proteins that fold in pieces?
(via sciencedaily.com) Original source A new study offers new insights into the evolution of foldable proteins.
Published Researchers uncover key mechanisms in chromosome structure development
(via sciencedaily.com) Original source Researchers are making strides in understanding how chromosome structures change throughout the cell's life cycle.
Published Retreating glaciers: Fungi enhance carbon storage in young Arctic soils
(via sciencedaily.com) Original source Melting Arctic glaciers are in rapid recession, and microscopic pioneers colonize the new exposed landscapes. Researchers revealed that yeasts play an important role in soil formation in the Arctic.
