Extreme bacteria on the space station are evolving to cope with the harsh conditions, not to make astronauts sick

For years, scientists on board the International Space Station (ISS) have been carrying out research to determine the effects of life in space on humans and microorganisms. In addition to high levels of radiation exposure, there is also concern that long-term exposure to microgravity could cause genetic mutations. Understanding this and taking countermeasures is essential if humanity is to become …

Scientists discover that billions of tons of "zombie" bacteria inhabit the ground beneath our feet

The discovery of what has been termed "subterranean Galapagos" was announced at Deep Carbon Observatory Tuesday on Tuesday, stating that many lifeforms have a lifespan of millions of years. DCO executive director Robert Hazen said the results were the "culmination" of the 1,000-strong collective of scientists "who opened our eyes to remarkable perspectives – emerging views of life that we …

How Bacteria Make Mars Livable

Humanity dreams of becoming an interplanetary species, but currently no other planet in our solar system can support a complex life. To make a planet like Mars hospitable to us, we must embark on a massive, decades-long terraforming effort. Much of what makes the earth habitable, such as breathing air, tolerable temperatures, etc., is the result of microbial activity from …

Antibiotic-resistant bacteria were found in the toilet of the space station

NASA has a watchful eye on the bacteria in the International Space Station (Microbial Observatory (M.O.)). The ISS hosts a variety of microbes, some of which endanger the health of astronauts. As part of its monitoring, M.O. has detected antibiotic-resistant bacteria on the toilet seat of the ISS. On space probes, there are always microorganisms that serve as storage facilities. …

Chemical 3D maps of individual bacteria – ScienceDaily

Scientists at the National Synchrotron Light Source II (NSLS-II) – a US Department of Energy (DOE) of the US Department of Science (DOE) at the US Brookhaven National Laboratory – use ultra-bright X-rays individual bacteria with higher concentration imaged spatial resolution than ever before. Their work, published in Scientific Reports shows an X-ray imaging technique called X-ray fluorescence microscopy (XRF) …

Colorful bacteria combine wastewater and light to clean energy

What you've just flushed into the toilet might be more useful than you ever thought. Researchers have found that some kind of purple bacteria can break down the organic compounds contained in the wastewater and possibly convert it into energy. Organic compounds in wastewater have been the subject of research for decades. For decades, engineers have been trying to figure …

Purple bacteria can produce hydrogen energy from organic waste

Purple bacteria can produce hydrogen energy from organic wastes. Researchers have found a new way to reduce CO2 emissions and convert wastewater into green generators. Organic compounds, which are typically found in industrial and domestic effluents, are known as a rich source of energy, bioplastics, and protein for animal feed. But while removing contaminants from wastewater, they are disposed of …

Photosynthesizing Bacteria Found Thriving Thousands of feet below the surface of the earth

Cyanobacterial cells, seen in red fluorescent color, bound to rock samples. Image: PNAS An international team of researchers has identified a particular population of cyanobacteria living in rocks deep beneath the surface of the earth – a surprising discovery as cyanobacteria need sunlight to survive. The scientists thought: A new study published this week in Proceedings of the National Academy …

Will bacteria ever die out? New research says yes, bigtime

Despite their ancient history and ubiquity, the diversity of bacteria remains one of the most cryptic chapters in the history of life. Credit: Stilianos Louca, University of British Columbia Bacteria emit substantial rates, though they seem to avoid the mass extinction that has struck greater forms of life on Earth, according to new research from the University of British Columbia …
