Plants may have first been able to grow on land due to bacterial genes

by

When aquatic plants first transitioned onto land, their success may have been due to genes they got from bacteria and fungi that let them take up nutrients from soil Life 1 March 2022 By Jake Buehler Plants may have taken root on land thanks to genes from bacteria Shutterstock/daniilphotos Around 500 million years ago, aquatic … Read more

Microbes convert industrial waste gases into commodity chemicals | Science

by

Chemicals cost more than just money: Today, petrochemical production spews out nearly 2% of the world’s greenhouse gas emissions. Now, researchers have taken an important step to vastly reduce that footprint, by using bacteria and waste gases from steel plants, rather than petroleum, as the starting ingredient for dozens of commodity chemicals. So far, the … Read more

Arctic Sponges Survive Dark, Hostile Conditions by Feasting on The Extinct

by

The bottom of the Arctic Ocean, below the permanent sea ice, is not a friendly place for life. Down there in the cold dark, nutrients and vegetation are sparse; it’s expected that any life that does manage to eke out an existence under these conditions would be likewise thin on the ground.   Scientists were … Read more

Gut Microbes Can Cause Obesity, And We’re Getting Closer to Understanding How

by

Medical researchers have discovered a molecule linking the tiny creatures that call our guts home to levels of fat in our bodies. “We now have a molecular mechanism that provides a starting point to understand our microbiome as a link between our diet and our body composition,” explained Emory University biochemist Dean Jones.   Hints … Read more

There’s a Bunch of Bacteria Having ‘Sex’ in Your Gut, And It’s Wilder Than We Thought

by

The human gut is the host of a rampant microscopic orgy. To survive, the microbes in our digestive tract are having ‘sex’ with each other on a regular basis, all in the name of swapping secrets on how to survive deadly doses of antibiotics.   A team of researchers from the University of Illinois at Urbana-Champaign … Read more

How Gut Microbe Symbiosis Helps Squirrels Keep Their Muscles During Hibernation

by

Ground squirrels spend the end of summer gorging on food, preparing for hibernation. They need to store a lot of energy as fat, which becomes their primary fuel source underground in their hibernation burrows all winter long.   While hibernating, ground squirrels enter a state called torpor. Their metabolism drops to as low as just … Read more

Microbes survive deep below the seafloor at temperatures up to 120°C

by

It was thought that microbes in sediments beneath the seafloor died above 80°C, but scientists have found some that can survive up to 120°C and possibly higher temperatures Life 25 January 2022 By Michael Le Page Bubbles coming out of a cave in the Pacific seabed near Japan 7maru/Getty Images Living microbes have been found … Read more

Microbes in The Ocean Depths Can Make Oxygen Without Sun. This Discovery Could Be Huge

by

For most of life on Earth, oxygen is essential, and sunlight is usually needed to produce that oxygen. But in an exciting twist, researchers have caught a common, ocean-dwelling microbe breaking all the rules.   Scientists have found that a microbe called Nitrosopumilus maritimus and several of its cousins, called ammonia oxidizing archaea (AOA), are able to … Read more

Bacteria: Microbes form complex structures like those seen in animals

by

Bacterial biofilms, slimy collections of microbes, can develop concentric rings containing cells with different biological features Life 6 January 2022 By Alex Wilkins Bacillus subtilis, a soil bacterium, can create concentric rings when it forms a biofilm Kwang-Tao Chou Bacterial biofilms contain a level of structural organisation that we thought was unique to plants and … Read more
