Microbes

The Mars 2020 rover will be touching down in Jezero Crater and now there’s more evidence this was a good choice. Two new studies have found that the landing site is rich in minerals that could preserve fossils of ancient microbes and other lifeforms.

Researchers at Rice University have developed a new air filter made of graphene foam, which can kill captured microbes with small zaps of electricity.

Antibiotics aren’t picky, blasting good and bad bacteria alike and messing up the delicate balance of the gut microbiome. But now researchers have developed a more targeted approach, with drugs that are able to zero in on specific species of bacteria.

Stand by to start space mining – not on an asteroid, but aboard the International Space Station (ISS). The experimental mining kit will use bacteria to study how microorganisms can be used to extract minerals and metals from rocks on asteroids, moons, and planets.

Modern Mars is a desolate husk of a planet, as far as life is concerned. But it’s not completely uninhabitable, since microbes could be hiding in the cracks of rocks and dirt. And now a new study has found a possible food source for these organisms – space dust.

It’s been suggested in the past that life could hitch a ride on asteroids or comets to jump from world to world – a process known as panspermia. Now, a Harvard team has calculated just how likely that scenario would be throughout the Milky Way. In short: extremely.

Livestock like sheep and cows are responsible for huge amounts of methane emissions. Now, an international team of researchers has analyzed the gut microbes of different sheep and found clues that may help us curb the problem.

Alien life is almost certainly out there somewhere, but because it’s most likely microscopic, it won’t be easy to spot. Now, researchers at the University of Illinois have come up with a new and fairly obvious sign of life: pasta-shaped rocks.

Scientists have just put the finishing touches on what they say is the first comprehensive catalog of bacteria and fungi living inside the ISS, describing a bacteria-filled environment not dissimilar to a gym or an office.

Microorganisms keep turning up in Earth’s most extreme environments. To test whether certain hardy microbes can survive the harsh conditions of space or Mars, colonies were placed on the outside of the International Space Station (ISS) for almost 18 months – and many managed to survive.

​Humans weren’t built for space travel. The immune system takes a beating, leaving us more vulnerable to infection. Astronauts have now tested a new antimicrobial coating on board the International Space Station (ISS), and found it kept space-faring bugs at bay for well over a year.

IBM’s annual 5 in 5 list is here. This time, all five technologies in this year’s list are designed to fix problems in every step of the food supply chain, from seed to your plate.
