With cold temperatures, low humidity and high levels of ultraviolet (UV) radiation, conditions 10 kilometers above Earth’s surface may seem inhospitable. But next time you’re flying, consider this: The air outside your airplane window might be filled with an array of microscopic life that affect... Read More

One widely-used tactic for defense against phage and other mobile genetic elements is to deploy a CRISPR-Cas system (click here and here) to recognize and chop them into pieces. Based on sequenced genomes, 60% of Bacteria and 90% of Archaea have the wherewithal to dispatch invaders this way. But... Read More

Symbiotic algae that live within reef-forming corals scoop up available nitrogen, store the excess in the form or uric acid crystals, and slowly feed it to the coral as needed, according to a study in mBio this week. Scientists have known for years that these symbiotic microorganisms serve up ni... Read More

I had a conversation with some colleagues last week about “personalized medicine,” which has been transformed now into the term “precision medicine.” The conversation revolved around what to do about the perceived effects of antibiotic treatment on the microbiota of individuals. How does one tre... Read More

I can tell you the exact date that I began to think of myself in the first-person plural — as a superorganism, that is, rather than a plain old individual human being. It happened on March 7. That’s when I opened my e-mail to find a huge, processor-choking file of charts and raw data from a labo... Read More

The swine flu virus that caused a 2009 pandemic has been found in elephant seals off the central California coast, according to new research. The study, published in the journal PLoS ONE, is the first report of the virus H1N1 in any marine mammal. Researchers are now being advised to wear protec... Read More

Certain types of anti-depressants have been linked to an increase in the risk of Clostridium difficile infection (CDI) finds a study in BioMed Central's open access journal BMC Medicine. Awareness of this link should improve identification and early treatment of CDI.

Certain types of anti-dep... Read More

Back when the Time Lord and I were still engaged, we went shopping for wedding rings. He only had one criteria: he wanted his ring to be made of platinum or a similar material forged in a supernova. It’s not quite as exotic as it sounds: most heavy elements were formed in supernovae, via a proce... Read More

Scientists have long believed that measuring the amount of HIV in a person’s blood is an indicator of whether the virus is actively reproducing.

A University of Delaware-led research team reports new evidence that hidden virus replication may be occurring within the body’s tissue, despite un... Read More

Researchers from the University of Tübingen have been able to show for the first time how microorganisms contributed to the formation of the world's biggest iron ore deposits. The biggest known deposits -- in South Africa and Australia -- are geological formations billions of years old. They are... Read More

A new study led by researchers from Harvard School of Public Health (HSPH) and the Wellcome Trust Sanger Institute in the UK has, for the first time, used genome sequencing technology to track the changes in a bacterial population following the introduction of a vaccine. The study follows how th... Read More

Bacteria that glide together… make art together? This contender in the Art of Science competition run by Princeton University in New Jersey, entitled The history of gliding, depicts the squiggly gliding paths of the bacteria Myxococcus xanthus.

M. xanthus are social bacteria that move in coor... Read More

A cocktail of non-pathogenic bacteria naturally occurring in the digestive tract of healthy humans can protect against a potentially lethal E. coli infection in animal models according to research presented today at the 113th General Meeting of the American Society for Microbiology. The researc... Read More

Researchers from CNRS, Université Toulouse III -- Paul Sabatier and IRD have elucidated new molecular mechanisms involved in resistance to visceral leishmaniasis, a serious parasitic infection. They have shown that dectin-1 and mannose receptors participate in the protection against the parasite... Read More

Scientists at the University of California, Davis have engineered a strain of photosynthetic cyanobacteria to grow without the need for light. They report their findings today at the 113th General Meeting of the American Society for Microbiology.

“In this work, we used synthetic biology appr... Read More

Bacterial resistance to antibiotics is bad enough, but what if drug resistance also gives bacteria the ability to fend off attacks by the immune system? In a study in mBio this week scientists identify a lose-lose situation with colistin and Acinetobacter baumannii: bacteria resistant to colisti... Read More
