According to Biochemist Graham Logan it did. In brief, containing digestion bi-products in parcels of poop meant that there was less for the bacteria to chew on. This led to less bacteria, and it was the bacteria who were burning up all the oxygen. Which meant there was more oxygen around to play with and the Cambrian Explosion ensued picked by pocksucket 12 months ago

The green dots indicate Pseudomonas syringae bacteria suspended in ice. Like other so-called biological ice nucleators, P. syringae gives water vapor a place to meet, join and form ice crystals that later fall to Earth. Brent Christner/Louisiana State University The sky is not an ethereal, sterile realm. It's teeming with bacteria, and scientists say that the microbes play a powerful role in prod... read full post picked by mutil8or 9 months ago

Derelict rocket stages that propelled four spacecraft toward the edges of our solar system and beyond are likely carrying Earthly bacteria out into the galaxy. picked by AutumnLotus 2 years ago

Human civilisation might have been millions of years more advanced today had it not been for massive chains of undersea volcanoes that erupted billions of years ago. New research has found that the birth of the oxygen-rich atmosphere we breathe was delayed 200 million years by marine volcanoes that destroyed the vital gas almost as fast as it was being exhaled by early bacteria. picked by AutumnLotus 1 year ago

Scientists in Switzerland are reporting that bacteria in the human mouth play a role in creating the distinctive flavors of certain foods. They found that these bacteria actually produce food odors from odorless components of food, allowing people to fully savor fruits and vegetables. picked by AutumnLotus 3 weeks ago

Ancient bacteria are able to survive nearly half a million years in harsh, frozen conditions, researchers said on Monday in a study that adds to arguments that permafrost environments on Mars could harbor life. picked by AutumnLotus 1 year ago

Brent Christner, LSU professor of biological sciences, in partnership with colleagues in Montana and France, recently found evidence that rain-making bacteria are widely distributed in the atmosphere. These biological particles could factor heavily into the precipitation cycle, affecting climate, agricultural productivity and even global warming. picked by AutumnLotus 9 months ago

A startling discovery by scientists at the Carnegie Institution puts a new twist on photosynthesis, arguably the most important biological process on Earth. But two studies suggest that certain marine microorganisms have evolved a way to break the rules--they get a significant proportion of their energy without a net release of oxygen or uptake of carbon dioxide. picked by AutumnLotus 9 months ago

A drug-resistant type of "superbug" bacteria called MRSA is more than eight times as common as believed in U.S. hospitals, putting patients at risk and posing a big hygiene problem, experts said on Tuesday. picked by DrNothing 1 year ago

Oxygen is constantly leaking out of Earth’s atmosphere and into space. Now, ESA’s formation-flying quartet of satellites, Cluster, has discovered the physical mechanism that is driving the escape. It turns out that the Earth’s own magnetic field is accelerating the oxygen away. picked by AutumnLotus 3 months ago

A new species of bacteria discovered living in one of the most extreme environments on Earth could yield a tool in the fight against global warming. The methane-eating microorganism is found in the geothermal field known as Hell’s Gate, near the city of Rotorua in New Zealand. picked by AutumnLotus 12 months ago

Metallireducens bacteria (green) is being used to digest uranium waste. This bacteria is able to survive in radioactive environments and turn the uranium waste from a soluble form (that can contaminate water supplies) to a solid form. picked by AutumnLotus 6 months ago

It doesn’t take brains to have some smarts. New research shows that even bacteria can evolve to predict upcoming events based on clues, like a dog salivating at the sound of the dinner bell. picked by 2manyusernames 7 months ago

Scientists have suspected that the three known domains of life -- eukaryotes, bacteria, and archaea -- branched off and went their separate ways around three billion years ago. But pinning down the time of that split has been an elusive task. Now, a team of scientists present direct evidence that the three domains of life coexisted at least as long as 2.7 billion years ago. picked by AutumnLotus 1 year ago

Scientists in Italy have found bacteria in the root of a tropical grass whose oils have been used in the cosmetic and perfumery industries. These bacteria seem to promote the production of essential oils, but also they change the molecular structure of the oil, giving it different flavours and properties. picked by suebe 1 month ago
