DartUniFrac Brings Megascale Computing to Microbiome Diversity Analysis
45+ min ago (512+ words) Researchers have introduced DartUniFrac, a new software tool designed to carry out UniFrac-based microbiome comparisons at a scale that was previously impractical....
Gut Microbe Link Revealed in Down Syndrome Obesity Risk
1+ hour, 25+ min ago (89+ words) People with Down syndrome face a markedly elevated risk of obesity and its metabolic complications compared with the general population, yet the biological reasons behind this vulnerability have remained frustratingly opaque. Now, a team of French researchers has traced part…...
Orphan Bitter Taste Receptors Found on Cell Surfaces, Hinting at Hidden
3+ hour, 40+ min ago (83+ words) Bitterness is often dismissed as a nuisance of the dinner plate, the flavor note that makes children push away Brussels sprouts and coffee drinkers reach for sugar. Yet for evolutionary biologists and physiologists, the ability to detect bitter compounds is…...
Bile Acids Emerge as Master Regulators Linking Gut Microbes, Immunity and
4+ hour, 38+ min ago (83+ words) Bile acids have long been typecast as the body’s detergents—steroid molecules manufactured by the liver, stored in the gallbladder and released into the small intestine to emulsify dietary fats. A new commentary published in Holistic Integrative Oncology argues that…...
Protozoan Waste Packets Turn Out to Be Shields for Dangerous Bacteria
6+ hour, 45+ min ago (602+ words) Every drop of natural water, every handful of soil, and even the interiors of our own bodies teem with protozoa, the single-celled predators that spend their lives hunting and consuming bacteria....
Machine Learning Reads Genome Sequences to Reveal Hidden Microbial
10+ hour, 4+ min ago (651+ words) Symbiosis is one of the most consequential forces in the history of life. Bacteria and archaea that live in intimate association with host organisms have shaped the evolution of animals, plants, fungi and protists, driving innovations ranging from nitrogen fixation…...
Seaweed Sugars May Rewire the Gut to Fight Fatty Liver Disease
21+ hour, 25+ min ago (57+ words) A sweeping new review argues that the ocean’s least glamorous exports—slippery polysaccharides extracted from seaweeds, sea cucumbers, and microalgae—could become powerful tools against metabolic dysfunction-associated steatotic liver disease, or MASLD, the most common chronic liver disorder worldwide. Writing…...
A genomic catalog of Earth’s bacterial and archaeal symbionts
23+ hour, 32+ min ago (918+ words) The assembly of a genomic catalog devoted specifically to bacterial and archaeal symbionts represents a meaningful shift in how large-scale microbiome resources are organized....
Bacteria may be producing testosterone inside the human body
1+ day, 9+ hour ago (1028+ words) A bacterium in the human urinary tract can convert a steroid made by the body into testosterone using two newly identified enzymes. A bacterium that lives inside the human urinary tract can turn a steroid the body already makes into…...
