Most mutations in the genes of the Salmonella bacterium have a surprisingly small negative impact on bacterial fitness. And this is the case regardless whether they lead to changes in the bacterial proteins or not. This is shown by Uppsala University scientists in an article being published toda... Read More

A team of Université Laval and Danisco researchers has just unlocked the secret of bacteria's immune system. The details of the discovery, which may eventually make it possible to prevent certain bacteria from developing resistance to antibiotics, are presented in the November 4 issue of the sci...

The rhizosphere is the narrow region of soil that is directly influenced by root secretions and associated soil microorganisms. A new study by scientists at Purdue University found that E. coli bacteria thrive in this region, critical to plant growth.
Scientists conducted the study by adding... Read More
It has long been thought disease-causing viruses can take shelter from your body's defenses, the immune system, by hiding inside cells. But a new study from British researchers found this is not the case.
Antibodies, which are proteins in the immune system, can latch on to some viruses and fo... Read More
For decades, they lived a mystery: Why were they able to survive with the AIDS virus, free of symptoms and the need for potent drugs, while so many others with the same germ turned deathly ill?
Their innate ability to keep HIV infections in check intrigued researchers, who suspected these peo... Read More
There is a great deal of interest in the impact of lactic acid bacteria on our health. Now a new study from the Faculty of Health and Society, Malmö University, in Sweden, shows that the occurrence of Lactobacillus reuteri in the body promotes health.
Humans have used lactic acid bacteria for... Read More
Over-probing airport security scans? Nope. Soft porn from the 22nd Century? Definitely not. These beautiful images of the human body are part of a new exhibition at the Royal Institution. Each was taken using the light emitted by the bioluminescent bacteria Photobacterium phosphorem. Artist Anne... Read More
Mutually-beneficial cooperation is a high ideal, but for bacteria and archaea, working together isn’t always a good solution. Now a team at Pennsylvania State University has worked out a system that could work better than inter-domain cooperation: by putting genes from a bacterium into an archa... Read More
Not long ago, microbiologists at the University of Texas Health Science Center at San Antonio solved a longstanding medical mystery: A common pathogen, Mycoplasma pneumoniae, was known to be involved in disease pathways throughout the body, but no one knew how it worked. Then the microbiologists... Read More
When a team of European researchers sought to discover how a class of antiviral drugs worked, they looked in an unlikely place: the sugar dish. A new research report appearing in the Journal of Leukocyte Biology suggests that a purified and modified form of a simple sugar chain may stop fast-act... Read More
The KwaZulu-Natal Research Institute for Tuberculosis and HIV (K-RITH) is seeking early career and established research scientists to work for a newly-formed institute in Durban, South Africa, that is dedicated to basic tuberculosis (TB) and HIV research in sub-Saharan Africa.
K-RITH was form... Read More
Malaria could be eradicated globally, just like smallpox was in 1979, through a global pincer movement, squeezing it closer to the equator from north and south.
"It could take 50 or 60 years," says Richard Feachem of the University of California, San Francisco, and author of "Shrinking the ma... Read More
Everyone knows about cancer. According to the World Health Organisation eight million people died of one of the many forms of cancer 2007 and this number is expected to grow to more than 12 million by 2030. However, unlike many other significant diseases, cancer is not confined to a continent or... Read More
New research by scientists at the University of Sheffield has shed light on how Earth's first plants began to colonize the land over 470 million years ago by forming a partnership with soil fungi.
The research, published in Nature Communications, has provided essential missing evidence showin... Read More
Tests by federal health authorities have found listeria bacteria at a Texas food processing plant after state health officials linked four deaths to contaminated celery from the facility.
The Food and Drug Administration says the results released Wednesday match testing done by the Texas Depa... Read More
Head and neck cancer patients were once primarily older heavy smokers and drinkers. Now, the majority who are diagnosed with the disease are closer to middle age (many ages 40 to 55) and developed it not from years of tobacco or alcohol use but rather because they engaged in oral sex.
This sh... Read More
