A person’s risk of pancreatic cancer might be tied to the microbes living in their mouths, a new study says. People have a more than tripled risk of pancreatic cancer if their mouths contain 27 types of bacteria and fungi, including some directly linked to gum disease, researchers reported Thursday in JAMA Oncology. “It is clearer than ever that brushing …

Life has influenced Earth’s atmosphere going back billions of years. But until two centuries ago, when humans started burning fossil fuels on an industrial scale, the most significant living climate controllers were organisms invisible to us: single-celled microbes. Small but mighty, microorganisms are nature’s chemists. At the very bottom of all biological processes, microbes break down, transform and supply the …

But there are other reasons to think it might work. Diet, for example, is well known to affect sleep. When a group of 15 healthy young men followed a high fat, high sugar diet for a week, this altered their brains’ electrical patterns during deep sleep, although it’s hard to draw firm conclusions from such a small sample size. Similarly, …

Life doesn’t always play by the tidy rules in textbooks. Most organisms use oxygen to produce ATP, which is energy used by cells. Some life forms, especially microbes, tap other chemicals when oxygen is scarce. The usual explanation says it’s one mode or the other. A team studying a microbe from a Yellowstone hot spring found something different. This bacterium …

If you thought diabetes care was only about insulin injections, strict diets, or endless exercise routines, here’s some news that might change your perspective. A group of Canadian scientists has uncovered a completely new way to manage diabetes by targeting something unexpected inside the gut. Let’s dig deeper into thisTheir research points to a little-known molecule called D-lactate, which is …

Deep below the seafloor, locked in a layer of 100-million-year-old sediment, a lifeform quietly lives. It’s not quite Godzilla, nor a long-lost Megalodon, but it does go to show how life on Earth can dwell under the most extreme and bizarre circumstances. Scientists discovered that communities of microbes living beneath the seafloor are able to survive in rock sediments for …

Russia just sent a mini menagerie to orbit. The Bion-M No. 2 biosatellite launched atop a Soyuz rocket from the Russia-run Baikonur Cosmodrome in Kazakhstan today (Aug. 20), rising off the pad at 1:13 p.m. EDT (1713 GMT; 10:13 p.m. local time in Kazakhstan). Onboard are 75 mice and 1,000 fruit flies, along with a variety of microbes, cell cultures …
