    A rover scanning the surface of Mars for evidence of life might want to check for rocks that look like pasta, researchers report in the journal Astrobiology. The bacterium that controls the formation of such rocks on Earth is ancient and thrives in harsh environments that are similar to conditions on Mars, said University of Illinois geology professor Bruce Fouke, who led the new, NASA-funded study. "It has an unusual name, Sulfurihydrogenibium yellowstonense," he said. The bacterium that controls the formation of such rocks on Earth is ancient and thrives in harsh environments that are similar to conditions on Mars,...

    For several million years, the Earth cycled through ice ages at a regular pace, but then, 1.25 million to 700,000 years ago, something changed: ice ages went from lasting 40,000 years to 100,000. … By looking at the microscopic shells of microorganisms called foraminifera, Adam Hasenfratz of the Geological Institute in Zürich, Switzerland, and colleagues, find evidence of a reduction in deep water circulation, causing less carbon dioxide to be released into the air. Oceanic changes in the Antarctic Zone could have ensured “that glacial conditions persisted despite orbital changes to the contrary”, the study says. The new research, presented...

    While the team found that the bacteria isolated from the ISS did contain different genes than their Earthling counterparts, those genes did not make the bacteria more detrimental to human health. The bacteria are instead simply responding, and perhaps evolving, to survive in a stressful environment. As the conversation about sending travelers to Mars gets more serious, there has been an increasing interest in understanding how microbes behave in enclosed environments. "People will be in little capsules where they cannot open windows, go outside or circulate the air for long periods of time," said Hartmann. "We're genuinely concerned about how...

    Scientists recently detected two previously unknown species of microbes in a Canadian dirt sample, and the specimens were so unusual that the researchers had to reorganize the tree of life to make room for them. The microbes, also known as protists, belong to a group with the tongue-twisting name hemimastigotes, and the first-ever genetic analysis of these peculiar microorganisms revealed that they were even stranger than anyone suspected. Hemimastigotes, first observed in the 1800s, were previously classified as a phylum within a much larger group known as a super-kingdom, though it was unclear where exactly they belonged. But new DNA...

NASA NASA planetary protection officer suggests loosening limits on exploring Mars for life By Paul VoosenFeb. 22, 2018 , 5:25 PM Is there life on the surface of Mars? The clock is ticking on scientists’ window to solve that long-standing question before astronauts—and the microbes that live on them—contaminate the planet. Today, at a meeting in Washington, D.C., of NASA’s planetary science advisory committee, the agency’s new planetary protection officer raised the possibility of opening up a few of...

    NASA astronauts successfully sequenced the DNA of microbes found aboard the International Space Station, marking the first time unknown organisms were sequenced and identified entirely in space. Previously, microbes had to be sent to Earth for analysis, and this new sequencing marks an important step in diagnosing astronaut illnesses and, someday, identifying any DNA-based life found on other planets... ...

    Bored at work? Find yourself staring into space? NASA may have the job for you. It comes with a six-figure salary and civil service protection — and duties include saving the Earth. It sounds like a job from the movie “Men in Black” about government employees saving the Earth from creepy aliens. Cassie Conley is NASA’s planetary protection officer, and that is — sort of — what she does, but on a smaller scale, and not quite as messy. “The job is defending Earth from aliens, but they’re microbes, not space invaders,” she told CBS News. We asked if bringing...

    Full title: Ancient bubbles in Australian rocks show early Earth's air weighed less than half today's atmosphere Air bubbles trapped in 2.7 billion-year-old Australian rock suggest the Earth's atmosphere weighed less than half of today and was much thinner than previously thought. Researchers analysed the size of air bubbles that formed at the top and bottom of lava flows along the Beasley River in Western Australia's Pilbara region almost three billion years ago and used the data to calculate the atmospheric pressure at the time. The results suggest that the air at the time exerted at most half the pressure...

    Love dark chocolate? Now you can eat it with much less guilt because scientists have discovered why it is so good for us. Previous studies have found daily consumption of dark chocolate reduces blood pressure and is good for the heart. Now scientists have discovered why this happens - and its down to how our guts ferment the fibre in cocoa beans. Researcher Maria Moore, from Louisiana State University said: 'We found that there are two kinds of microbes in the gut: the 'good' ones and the 'bad' ones. 'The good microbes, such as Bifidobacterium and lactic acid bacteria, feast...

    Microbes possibly feeding on the remains of an ancient forest may be generating billions of tons of methane deep beneath Antarctic ice, a new study suggests. The amount of this greenhouse gas — which would exist in the form of a frozen latticelike substance called methane hydrate — lurking beneath the ice sheet rivals that stored in the world's oceans, the researchers said. If the ice sheet collapses, the greenhouse gas could be released into the atmosphere and dramatically worsen global warming, researchers warn in a study published in the Aug. 30 issue of the journal Nature. "There could be...

    There has been a long-lived bit of Apollo moon landing folklore that now appears to be a dead-end affair: microbes on the moon. The lunar mystery swirls around the Apollo 12 moon landing and the return to Earth by moonwalkers of a camera that was part of an early NASA robotic lander – the Surveyor 3 probe. On Nov. 19, 1969, Apollo 12 astronauts Pete Conrad and Alan Bean made a precision landing on the lunar surface in Oceanus Procellarum, Latin for the Ocean of Storms. Their touchdown point was a mere 535 feet (163 meters) from the Surveyor 3...

    Federal study confirms microbes have eaten most of the Gulf Oil Spill A study by researchers from Texas A&M and University of California in Santa Barbara have found that all of the methane gas released from the BP spill in the Gulf of Mexico have been consumed by tiny microbes. Methane gas amounts 100,000 times higher than normal at the time of their release have completely disappeared after only 120 days. Some scientists had raised concerns that dissolved methane and other oil residue would continue to plague the Gulf for years or even decades. This is turning out not...

    Seaswarm, an autonomous, solar-powered skimmer, may be the answer to less expensive and more efficient methods for cleaning up future oil spills. The robot prototype promises to absorb 20 times its weight in oil. Created by researchers at MIT’s Senseable City Lab, Seaswarm employs a conveyor belt of absorbent, nanowire mesh. The specially deigned mesh can suck up oil on the water’s surface and then process and dispose of the oil it’s collected. The Seaswarm can continue to absorb more of the spill while the robot autonomously navigates and cleans the ocean for weeks on end. Researchers claim that 5,000...

    Life originated in a nebular cloud, over 10 billion years ago, but may have had multiple origins in multiple locations, including in galaxies older than the Milky Way. Multiple origins could account for the different domains of life: archae, bacteria, eukaryotes. The first steps toward life may have been achieved when self-replicating nano-particles initially comprised of a mixture of carbon, calcium, oxygen, hydrogen, phosphorus, sugars, and other elements and gasses were combined and radiated, forming a nucleus around which a lipid-like permeable membrane was established, and within which DNA-bases were laddered together with phosphates and sugars; a process which may...

    Where is all the oil? Nearly two weeks after BP finally capped the biggest oil spill in U.S. history, the oil slicks that once spread across thousands of miles of the Gulf of Mexico have largely disappeared. Nor has much oil washed up on the sandy beaches and marshes along the Louisiana coast. And the small cleanup army in the Gulf has only managed to skim up a tiny fraction of the millions of gallons of oil spilled in the 100 days since the Deepwater Horizon rig went up in flames.
