Published Fewer meals may prevent Type 2 diabetes, obesity
(via sciencedaily.com) Original source When intermittent fasting became all the rage among Hollywood celebrities, skeptics balked at the idea of skipping meals. But new research suggests the celebs might not have been that far off. The review found that a specific type of restricted eating may reduce the chances of developing Type 2 diabetes and improve your overall health. Known as time-restricted eating, this type of fasting means having regular but fewer meals, cutting out late-night snacks and not eating for 12 to 14 hours (often overnight).
Published Technique restores healthy bacterial balance in C-section babies
(via sciencedaily.com) Original source Newborns delivered by cesarean section who are swabbed with the vaginal fluid of their mothers after birth have beneficial bacteria restored to their skin surface and stools, according to a new study. In the first randomized study of its kind, a team of researchers found the process, known as vaginal seeding, definitively engrafted new strains of maternal bacteria in the babies' bodies.
Published Metaverse could put a dent in global warming
(via sciencedaily.com) Original source For many technology enthusiasts, the metaverse has the potential to transform almost every facet of human life, from work to education to entertainment. Now, new research shows it could have environmental benefits, too.
Published Ants have a specialized communication processing center that has not been found in other social insects
(via sciencedaily.com) Original source Have you ever noticed an ant in your home, only to find that a week later the whole colony has moved in? The traps you set up catch only a few of these ants, but soon, the rest of the colony has mysteriously disappeared. Now, a study explores how certain danger-signaling pheromones -- the scent markers ants emit to communicate with each other -- activate a specific part of the ants' brains and can change the behavior of an entire nest.
Published Photosynthesis, key to life on Earth, starts with a single photon
(via sciencedaily.com) Original source A cutting-edge experiment has revealed the quantum dynamics of one of nature's most crucial processes.
Published Earth was created much faster than we thought: This makes the chance of finding other habitable planets in the Universe more likely
(via sciencedaily.com) Original source Over the past decades, researchers thought Earth was created over a period of more than 100 million years. However, a new study from suggests that the creation of Earth was much more rapid, and that water and other essential ingredients for life were delivered to Earth very early on.
Published The life below our feet: Team discovers microbes thriving in groundwater and producing oxygen in the dark
(via sciencedaily.com) Original source A survey of groundwater samples drawn from aquifers beneath more than 80,000 square miles of Canadian prairie reveals ancient groundwaters harbor not only diverse and active microbial communities, but also unexpectedly large numbers of microbial cells. Strikingly, some of these microbes seem to produce 'dark oxygen' (in the absence of sunlight) in such abundance that the oxygen may nourish not only those microbes, but may leak into the environment and support other oxygen-reliant microbes that can't produce it themselves.
Published Altered gut bacteria may be early sign of Alzheimer's disease
(via sciencedaily.com) Original source Alzheimer's disease causes changes to the brain that begin two decades or more before symptoms appear. A study reveals that the bacteria that live in the gut also change before Alzheimer's symptoms arise, a discovery that could lead to diagnostics or treatments for Alzheimer's disease that target the gut microbiome.
Published Elimination of type of bacteria suggests treatment for endometriosis
(via sciencedaily.com) Original source A research group has discovered that using an antibiotic to target Fusobacterium, a common bacterium that causes inflammation, improved the symptoms of endometriosis. Their findings suggest an alternative treatment for the disease.
Published Newly planted vegetation accelerates dune erosion during extreme storms, research shows
(via sciencedaily.com) Original source Newly planted vegetation on coastal sand dunes can accelerate erosion from extreme waves.
Published Preserving forests to protect deep soil from warming
(via sciencedaily.com) Original source An innovative, decade-long experiment in the foothills of California's Sierra Nevada mountains shows carbon stocks buried deep underground are vulnerable to climate change. The findings have implications for mitigating global warming through the natural carbon sinks provided by soil and forests which capture 25% of all carbon emissions.
Published Researchers find high risk to amphibians if fungal pathogen invades North America
(via sciencedaily.com) Original source New research indicates the fungal pathogen Batrachochytrium salamandrivorans (Bsal) could be devastating to amphibian biodiversity if introduced to North America.
Published Scientists discover small RNA that regulates bacterial infection
(via sciencedaily.com) Original source Researchers have identified the major mechanism behind the transition between chronic and acute P. aeruginosa infections. Their research findings can inform the development of future treatments for life-threatening acute infections.
Published A machine learning approach to freshwater analysis
(via sciencedaily.com) Original source A team of researchers has applied a machine learning model to explore where and to what extent human activities are contributing to the hydrogeochemical changes, such as increases in salinity and alkalinity in U.S. rivers. The group used data from 226 river monitoring sites across the U.S. and built two machine learning models to predict monthly salinity and alkalinity levels at each site.
Published First illustration of the molecular machinery that makes cilia beat
(via sciencedaily.com) Original source The first image of the structures that power human cilia -- the tiny, hairlike projections that line our airways -- has now been produced and it could lead to much-needed treatments for people with rare cilial diseases.
Published Scientists investigate the evolution of animal developmental mechanisms, show how some of Earth's earliest animals evolved
(via sciencedaily.com) Original source Lacking bones, brains, and even a complete gut, the body plans of simple animals like sea anemones appear to have little in common with humans and their vertebrate kin. Nevertheless, new research shows that appearances can be deceiving, and that a common genetic toolkit can be deployed in different ways to drive embryological development to produce very different adult body plans. It is well established that sea anemones, corals, and their jellyfish relatives shared a common ancestor with humans that plied the Earth's ancient oceans over 600 million years ago. A new study from the Gibson Lab, published in Current Biology on June 13, 2023, illuminates the genetic basis for body plan development in the starlet sea anemone, Nematostella vectensis. This new knowledge paints a vivid picture of how some of the earliest animals on earth progressed from egg to embryo to adult.
Published New method traces ancestry of hybrid plants and animals
(via sciencedaily.com) Original source Hybrid plants and animals have complicated genomes. A biologist has discovered a way to reveal their parent species.
Published Aluminium-ion batteries with improved storage capacity
(via sciencedaily.com) Original source Scientists develop positive electrode material using an organic redox polymer based on phenothiazine. Aluminium-ion batteries containing this material stored an unprecedented 167 milliampere hours per gram, outperforming batteries using graphite as electrode material. Aluminium-ion batteries are considered a promising alternative to conventional batteries that use scarce raw materials such as lithium.
Published Marine environment at risk due to ship emissions
(via sciencedaily.com) Original source Researchers used four different types of port environments to investigate the levels of contaminants emitted from five different sources. They found that the combined emissions of metals and environmentally hazardous substances is putting the marine environment at risk. Ninety per cent of the harmful emissions came from ships fitted with scrubbers, whose purpose is to clean their exhaust gases.
Published The latest weapon against cancer is ... a keto diet?
(via sciencedaily.com) Original source Keto diets shrink pancreatic and colorectal tumors by starving them of the glucose they need to survive. But they also speed up development of a lethal wasting disease called cachexia. In mice, researchers have found that pairing keto with a corticosteroid prevents cachexia and increases survival.
