Published Atlas of proteins reveals inner workings of cells
(via sciencedaily.com) Original source Researchers discover how proteins behave inside cells using AI, which has the potential to guide drug design.
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 Researchers show promising material for solar energy gets its curious boost from entropy
(via sciencedaily.com) Original source Researchers discovered a microscopic mechanism that solves in part the outstanding performance achieved by a new class of organic semiconductors known as non-fullerene acceptors (NFAs).
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 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 A 2D device for quantum cooling
(via sciencedaily.com) Original source Engineers have created a device that can efficiently convert heat into electrical voltage at temperatures lower than that of outer space. The innovation could help overcome a significant obstacle to the advancement of quantum computing technologies, which require extremely low temperatures to function optimally.
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 Cool roofs are best at beating cities' heat
(via sciencedaily.com) Original source Painting roofs white or covering them with a reflective coating would be more effective at cooling cities like London than vegetation-covered 'green roofs,' street-level vegetation or solar panels, finds a new study led by UCL researchers.
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 A new breakthrough in understanding regeneration in a marine worm
(via sciencedaily.com) Original source The sea worm Platynereis dumerilii is only a few centimeters long but has a remarkable ability: in just a few days, it can regenerate entire parts of its body after an injury or amputation. By focusing more specifically on the mechanisms at play in the regeneration of this worm's tail, a research team has observed that gut cells play a role in the regeneration of the intestine as well as other tissues such as muscle and epidermis.
