In the search for new life, scientists have studied the depths of the ocean and the lips of steaming volcanoes. They've looked on Mars and the moons of Jupiter, and even planets beyond this solar system.
Dr. David Relman went searching inside his own mouth. On a routine dental visit in 1998, ... Read More
Scientists' finding is a major breakthrough in understanding a decades-old problem of how bacteria detect environmental changes.
A team of scientists led by Assistant Professor Ganesh S Anand and Professor Linda J. Kenney from the National University of Singapore (NUS) Department of Biologica... Read More
It was a provocative finding: strange bacteria in a California lake that thrived on something completely unexpected — arsenic. What it suggested is that life, a very different kind of life, could possibly exist on some other planet.
The research, published by a leading scientific journal in 2... Read More
A third of the world’s human population is infected with a dormant tuberculosis bacteria, primarily people living in developing countries. The bacteria presents a lifelong TB risk. Recent research out of the University of Copenhagen demonstrates that the risk of tuberculosis breaking out is four... Read More
Cholera is an extremely virulent intestinal infection caused by ingestion of the bacterium Vibrio cholerae (V. cholerae). EU researchers elucidated the molecular mechanisms behind expression of virulence genes with important implications for new therapies.

One year on from Europe’s worst recorded outbreak of Escherichia coli infection, governments have made little progress towards improving the monitoring and reporting systems that allowed the crisis to drag on for weeks. The disease, which was spread by contaminated fenugreek sprouts, swept acros... Read More
The second of two papers on avian influenza H5N1 virus that caused such a furor in the past year was published today in the journal Science. I have carefully read the paper by Fouchier and colleagues, and I assure you that it does not enable the production of a deadly biological weapon. The resu... Read More
India has been free of polio for over one year. This is a remarkable accomplishment, considering that just 30 years ago the country recorded 200,000 cases of the disease annually, or one every three minutes. With polio endemic in two neighboring countries, Pakistan and Afghanistan, and in the mo... Read More
A team of dentists and scientists from Newcastle University are developing a new product from a marine microbe to protect dentures, teeth and gums from bacteria in the mouth.
They are using an enzyme isolated from a marine bacterium Bacillus licheniformis found on the surface of seaweed which... Read More
In the first field study of its kind researchers at Royal Holloway, University of London and the University of Oxford have investigated the competitive dynamics of pathogenic and non-pathogenic strains of bacteria.
Bacteria are increasingly seen as living and interacting in groups and sharing... Read More
With NASA’s Curiosity Rover safely on Mars and ready to search for signs of life, back on Earth attempts are underway to engineer bacteria that could thrive on the Red Planet.
A team of undergraduates from Stanford and Brown Universities are busy applying synthetic biology to space exploratio... Read More
A team of researchers led by scientists at Rockefeller University have discovered that a protein once thought to be mainly involved in antiviral immunity is in fact more important in fighting bacterial infections and could provide new mechanisms for treating diseases like tuberculosis, which is ...

A scientific endeavour carried out by two French groups belonging to INSERM and CNRS at Aix-Marseilles University shows for the very first time that both bacterium adhesion to and bacterium motion on a surface are driven by the same mechanism (see paper in PNAS: "Wet-surface–enhanced ellipsometr...

There is no parasite that is universally infective, even generalist parasites that can infect many different host species are usually limited to a particular taxonomic group - such as fish, insects, or mammals. Some parasites may infect a broad spectrum of hosts during one stage of their life-cy... Read More
Scientists studying loss of bone and muscle mass among astronauts find that spaceflight’s effects on microscopic worms may help them live longer.
The researchers discovered that spaceflight suppresses accumulation of toxic proteins that normally accumulate within aging muscle.
In addition,... Read More
Signals from natural intestinal bacteria are necessary for an effective immune response to various viral or bacterial germs. This was the result of experiments by a research team led by Prof. Dr. Andreas Diefenbach and Stephanie Ganal at the Institute of Medical Microbiology and Hygiene of the F... Read More
Ancient DNA of the bacteria causing syphilis, the Treponema pallidum pallidum, can be recovered from the ancient bones of newborns. This is the conclusion reached by a study led by Universitat Autònoma de Barcelona (UAB), which was able to obtain the genetic material from the bacteria in more th... Read More
Research led by St. Jude Children’s Research Hospital scientists has identified a possible new approach to defeating bacterial infections by targeting an innate immune system component in a bid to invigorate the immune response.
In this study, researchers demonstrated that the primary functio... Read More
Bloodstream infections caused by the MRSA superbug may be on the decline in communities across the U.S., according to a large study of military personnel.
Previous data from the Centers for Disease Control and Prevention show a drop in infections contracted in healthcare settings. But the tra... Read More
