Research led by scientists at the University of Dundee has uncovered the workings of a 'bacterial raincoat' that helps to protect bacteria from the changing environment in which they live.
Many bacteria grow in large communities called biofilms, where the cells work together and produce a sti... Read More
A clinical trial of an innovative vaccine is occurring. The vaccine could offer hope to patients with advanced ovarian cancer. The vaccine, which is derived from the patient's tumor cells, is designed to jumpstart the patient's immune system to attack and kill cancer cells.
Ovarian cancer is ... Read More
Activating a mother’s immune system during her pregnancy disrupts the development of neural cells in the brain of her offspring and damages the cells' ability to transmit signals and communicate with one another, researchers with the UC Davis Center for Neuroscience and Department of Neurology h...

Researchers at Duke University say they have created a blood test that can determine whether a person's respiratory illness is caused by a bacterial infection or a virus, with over 90 percent accuracy.
What's more, the test only takes about 12 hours to get results. Current methods take severa... Read More
Some time ago, we asked this Talmudic Question: Can you think of a place on Earth where there is free water but no microbes? (A sterile flask of nutrient broth in a lab, the insides of the body, or an IV bag in a hospital don't count.) Someone answered that perhaps deep in Antarctica there would... Read More
Tiny electrical wires protrude from some bacteria and contribute to rock and dirt formation. Researchers studying the protein that makes up one such wire have determined the protein's structure. The finding is important to such diverse fields as producing energy, recycling Earth's carbon and min... Read More
Doses of a human gut microbe helped to reverse behavioral problems in mice with autism-like symptoms, researchers report today in Cell. The treatment also reduced gastrointestinal problems in the animals that were similar to those that often accompany autism in humans.
The work builds on prev... Read More
A strain of bacteria that causes skin and soft tissue infections in humans originally came from cattle, according to a study to be published in mBio®, the online open-access journal of the American Society for Microbiology. The researchers who conducted the genetic analysis of strains of Staphyl... Read More
Here I remember a person who a great deal of influence on my views about microbiology in the classroom, and the laboratory: the late Abigail Salyers. RIP, Abigail. Read More
A major new technology has been developed by The University of Nottingham, which enables all of the world’s crops to take nitrogen from the air rather than expensive and environmentally damaging fertilisers.
Nitrogen fixation, the process by which nitrogen is converted to ammonia, is vital fo... Read More
Some strains of the avian H7N9 influenza that emerged in China this year have developed resistance to the only antiviral drugs available to treat the infection, but testing for antiviral resistance can give misleading results, helping hasten the spread of resistant strains. The authors of a stud... Read More
Not all viruses are bad for us. Some of them might even help up us fight off bacterial infections someday.
Naturally occurring viruses called bacteriophages attack specific types of bacteria. So researchers at the University of Leicester decided to try and take advantage of phages' bacteria-d... Read More
Transplanting fecal matter has been one of the best remedies at treating a tough bacterial infection known as Clostridium difficile (C. diff). Scientists are now saying they can give all the benefits of poop in a tiny pill.
This new pill method is a less yucky way to do "fecal transplants." A... Read More
From a bacteria’s perspective the environment is one big DNA waste yard. Researchers have now shown that bacteria can take up small as well as large pieces of old DNA from this scrapheap and include it in their own genome. This discovery may have major consequences – both in connection with resi... Read More
“Implementation of infant rotavirus vaccination in 2006 has substantially reduced the burden of severe gastroenteritis among U.S. children younger than 5 years,” write Paul A. Gastanaduy, M.D., M.P.H., of the Centers for Disease Control and Prevention, Atlanta, and colleagues. “Whether indirect ... Read More
The bacteria in the human mouth – particularly those nestled under the gums – are as powerful as a fingerprint at identifying a person’s ethnicity, new research shows.
Scientists identified a total of almost 400 different species of microbes in the mouths of 100 study participants belonging t... Read More
Australian researchers have found that zinc can 'starve' one of the world's most deadly bacteria by preventing its uptake of an essential metal.
The finding, by infectious disease researchers at the University of Adelaide and The University of Queensland, opens the way for further work to des... Read More
Bacterial proteins could alter precipitation patterns and climate-change models.
Proteins can help grow teeth and bones in the body, crops in the ground, and even ice in the atmosphere. Some proteins have an uncanny knack for kick starting ice formation at unusual temperatures, and they have ... Read More
Doses of a human gut microbe helped to reverse behavioural problems in mice with autism-like symptoms, researchers report today in Cell. The treatment also reduced gastrointestinal problems in the animals that were similar to those that often accompany autism in humans.

Fernan Federici’s microscopic images of plants, bacteria, and crystals are a classic example of finding art in unexpected places.
A couple years ago, Federici was working on his Ph.D. in biological sciences at Cambridge University studying self-organization, the process by which things organi... Read More
