Published Using different flours for sourdough fosters different bacteria -- and flavors
(via sciencedaily.com) Original source A new study of the microbial ecosystem in sourdough finds that using different types of flour fosters distinct bacterial communities, and that these differences contribute to the variation of sourdough aromas and flavors.
Published An AI tool that can help forecast viral outbreaks
(via sciencedaily.com) Original source EVEscape predicts future viral mutations, new variants using evolutionary, biological information.
Published Doubling down on known protein families
(via sciencedaily.com) Original source A massive computational analysis of microbiome datasets has more than doubled the number of known protein families. This is the first time protein structures have been used to help characterize the vast array of microbial 'dark matter.'
Published Mummified feces reveals pre-Columbian cultures of the Caribbean consumed a diversity of plants
(via sciencedaily.com) Original source DNA analysis of mummified feces reveals two pre-Columbian Caribbean cultures ate a wide variety of plants, like maize, sweet potato, and peanuts -- and tobacco and cotton traces were detected too, according to a new study.
Published TB vaccine discovery paves path to end number one killer of people living with HIV
(via sciencedaily.com) Original source Scientists have discovered a tuberculosis (TB) vaccination strategy that could prevent the leading cause of death among people worldwide living with HIV. The results showed that, when given intravenously, the only commercially available vaccine against TB successfully and safely prevents lung infection in monkeys infected with the simian, or primate, form of HIV, called SIV. This is despite the vaccine being contraindicated for people living with HIV.
Published How plant-derived nutrients can affect the gut and brain
(via sciencedaily.com) Original source Can plant-derived nutrients alter gut bacteria to affect brain function? Scientists investigated this question in a study of overweight adults. Their findings suggest that dietary fiber can exert influence on both the composition of gut bacteria and the reward signals in the brain and associated food decision-making.
Published Modular dam design could accelerate the adoption of renewable energy
(via sciencedaily.com) Original source Scientists have developed a new modular steel buttress dam system designed to resolve energy storage issues hindering the integration of renewable resources into the energy mix. The new modular steel buttress dam system facilitates the rapid construction of paired reservoir systems for grid-scale energy storage and generation using closed-loop pumped storage hydropower, cutting dam construction costs by one-third and reducing construction schedules by half.
Published Evidence from the remains of 1918 flu pandemic victims contradicts long-held belief that healthy young adults were particularly vulnerable
(via sciencedaily.com) Original source New analysis of the remains of victims of the 1918 influenza pandemic, which killed an estimated 50 million people worldwide, contradicts the widespread belief the flu disproportionately impacted healthy young adults.
Published New discovery may 'unlock' the future of infectious disease and cancer treatment
(via sciencedaily.com) Original source Researchers have identified a 'guard mechanism' for a protein which attacks microbes in infected cells, opening the possibility of new treatments for Toxoplasma, Chlamydia, Tuberculosis and even cancer.
Published Study shows prior exposure to common virus shields against birth defects and miscarriage
(via sciencedaily.com) Original source Researchers found that pre-existing immunity to Cytomegalovirus (CMV) can limit its transmission during pregnancy and protect against associated birth defects. The study marks an important step toward the development of a vaccine to protect mothers and their babies against the virus, which is a leading cause of miscarriage and birth defects.
Published The end of genes: Routine test reveals unique divergence in genetic code
(via sciencedaily.com) Original source Scientists testing a new method of sequencing single cells have unexpectedly changed our understanding of the rules of genetics. The genome of a protist has revealed a seemingly unique divergence in the DNA code signalling the end of a gene, suggesting the need for further research to better understand this group of diverse organisms.
Published Shining a light on tiny, solar-powered animals
(via sciencedaily.com) Original source Acoels have been found to host a wide diversity of symbiotic, photosynthetic microalgae.
Published Ruffed grouse population more resilient than expected, genetic study finds
(via sciencedaily.com) Original source Despite decades of decline, a genetic analysis of ruffed grouse reveals that Pennsylvania's state bird harbors more genetic diversity and connectivity than expected. The findings suggest that the iconic game bird could be maintained in persistent numbers if appropriate protections are implemented.
Published New type of tiny wasp comes with mysterious, cloud-like structures at ends of antennae
(via sciencedaily.com) Original source Fossil researchers have discovered a novel genus and species of tiny wasp with a mysterious, bulbous structure at the end of each antenna.
Published Proteins roll the dice to determine bee sex
(via sciencedaily.com) Original source To date it has been unclear exactly how the sex of a bee is determined. A research team comprising biologists and chemists has now identified a key gene and the molecular mechanism linked with it. They describe how this process is similar to a game involving two dice.
Published Meadow Spittlebug's record-breaking diet also makes it top disease carrier for plants
(via sciencedaily.com) Original source New research fueled in part by citizen scientists reveals that the meadow spittlebug—known for the foamy, spit-like urine released by its nymphs—can feed on at least 1,300 species of host plants, more than twice the number of any other insect.
Published Hospital superbugs: Could one vaccine rule them all?
(via sciencedaily.com) Original source A new study shows that a single dose of the vaccine, administered in mouse models, put immune cells into 'Incredible Hulk' mode, providing rapid protection against nine different bacteria and fungi species that lurk in healthcare settings.
Published Avatars to help tailor glioblastoma therapies
(via sciencedaily.com) Original source Scientists have created a new zebrafish xenograft platform to screen for novel treatments for an aggressive brain tumor called glioblastoma, according to a new study.
Published Wastewater detects signs of antimicrobial resistance in aged care facilities
(via sciencedaily.com) Original source A new study analyzing wastewater samples from several aged care facilities and retirement homes, has uncovered worrying signs of antimicrobial resistance (AMR), a concerning trend in aged care facilities.
Published Ancient technology turns plant-based cheese into 'something we want to eat'
(via sciencedaily.com) Original source To produce plant-based cheeses that feel and taste like dairy cheese, scientists have their sights set on fermentation. In a new research result, scientists demonstrate the potential of fermentation for producing climate-friendly cheeses that people want to eat.
