When people and equipment travel to the International Space Station, microbes like bacteria and fungi also come along for the ride.

Nitrogen is vital for all forms of lifeĀ¬: It is part of proteins, nucleic acids and other cell structures. Thus, it was of great importance for the development of life on early Earth to be able to convert gaseous dinitrogen from the atmosphere into a bio-available form - ammonium.

Microbial Tracking-3 (MT-3) is a NASA Space Biology investigation cataloging and characterizing potential disease-causing microorganisms aboard the International Space Station (ISS).

International drilling efforts over the last decades into the seafloor have provided increasing evidence for the existence of an extensive deep biosphere below the seafloor.

The yeast C. albicans is a common opportunistic fungal pathogen responsible for a variety of superficial infections as well as systemic and more severe infections in humans.

Though it might seem inanimate, the soil under our feet is very much alive. It's filled with countless microorganisms actively breaking down organic matter, like fallen leaves and plants, and performing a host of other functions that maintain the natural balance of carbon and nutrients stored in the ground beneath us.

Cyanobacteria are one of the unsung heroes of life on Earth. They first evolved to perform photosynthesis about 2.4 billion years ago, pumping tons of oxygen into the atmosphere - a period known as the Great Oxygenation Event - which enabled the evolution of multicellular life forms.

A team led by University of Minnesota researchers has discovered that deep-sea bacteria dissolve carbon-containing rocks, releasing excess carbon into the ocean and atmosphere.

Below the verdant surface and organic rich soil, life extends kilometers into Earth's deep rocky crust. The continental deep subsurface is likely one of the largest reservoirs of bacteria and archaea on Earth, many forming biofilms - like a microbial coating of the rock surface.

It's like something out of science fiction. Research led by Bigelow Laboratory for Ocean Sciences has revealed that a group of microbes, which feed off chemical reactions triggered by radioactivity, have been at an evolutionary standstill for millions of years.

In Search Of The First Bacterium

Roughly five years ago, Institute Head Prof. Dr. William (Bill) Martin and his team introduced the last universal common ancestor of all living organisms and named it "LUCA". It lived approximately 3.8 billion years ago in hot deep sea hydrothermal vents.

In order to withstand the rigors of space on deep-space missions, food grown outside of Earth needs a little extra help from bacteria. Now, a recent discovery aboard the International Space Station (ISS) has researchers may help create the 'fuel' to help plants withstand such stressful situations.

How To Have Memories Without Having A Brain

Having a memory of past events enables us to take smarter decisions about the future.

Bacteria And Algae Get Rides In Clouds

Human health and ecosystems could be affected by microbes including cyanobacteria and algae that hitch rides in clouds and enter soil, lakes, oceans and other environments when it rains, according to a Rutgers co-authored study.

For the first time, researchers have mapped the biological diversity of marine sediment, one of Earth's largest global biomes. Although marine sediment covers 70% of the Earth's surface, little was known about its global patterns of microbial diversity.

Air-Eating Microbes

In their first follow-up to a high-profile 2017 study which showed microbes in Antarctica have a unique ability to essentially live on air, researchers from UNSW Sydney have now discovered this process occurs in soils across the world's three poles.

In a publication in Nature Communications last Friday, NIOZ scientists Nina Dombrowski and Anja Spang and their collaboration partners describe a previously unknown phylum of aquatic Archaea that are likely dependent on partner organisms for growth while potentially being able to conserve some energy by fermentation.

A study conducted by a team of national laboratory and NASA researchers has found that the environment of the International Space Station is affected by the microbial composition of the astronauts themselves.

Two particularly tenacious species of bacteria have colonized the potable water dispenser aboard the International Space Station (ISS), but a new study suggests that they are no more dangerous than closely related strains on Earth.

Sometimes doing science is as simple as wiping up. NASA astronaut Jack Fisher is seen here using a wet wipe on the surfaces of the European Cupola module of the International Space Station.
