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
An investigation led by UCSF has found that the risk of female-to-male HIV transmission is increased three fold for women with bacterial vaginosis, a common disorder in which the normal balance of bacteria in the vagina is disrupted.
The new research assessed the association between bacterial... 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

The more controversial of two papers describing how the lethal H5N1 bird flu could be made easier to spread was published on Thursday, six months after a scientific advisory board suggested that the papers’ most potentially dangerous data be censored.
The paper’s publication, in the journal S... 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
One of the most economically devastating diseases in the world for those who raise cows, sheep, pigs, goats, deer and other cloven-hoofed animals is foot and mouth Disease (FMD). This incredibly contagious and fast-spreading disease causes fever, blisters on the feet and mouth (hence the name), ... Read More
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
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 ...

Studies suggest that infants who grow up with dogs in their home are less likely to develop asthma. Researchers may now have found one reason why. Pets, dogs in particular, may protect infants from the effects of a common virus, respiratory syncytial virus (RSV).
Infants with severe RSV infec... Read More
Life in a high-pressured environment with practically nothing to eat might be ok for high-fashion models, but it’s an unlikely lifestyle choice for a single cell whose usual overriding goal is to become two cells. Yet the largest living ecosystem on Earth—the deep biosphere—is comprised of micro... Read More
Johnson & Johnson said Monday that it is seeking U.S. approval for the first new type of medicine to fight deadly tuberculosis in more than four decades.
The experimental drug, called bedaquiline, also would be the first medicine specifically for treating multi-drug-resistant tuberculosis. Th... Read More
Happy Fourth of July! In honor of this historic holiday we’ve compiled a list showing how infectious diseases and vaccines have affected the lives of our most heralded leaders – the American presidents. These concise accounts are evidence that diseases can strike anyone, anywhere at any time, an... Read More
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
