When my laboratory discovered the cell receptor for poliovirus in 1989, many new research directions were suddenly revealed – such as creating a mouse model for poliomyelitis. One application we did not think of was to use the receptor to screen samples of drinking water for the presence of viru... Read More
Conventional wisdom says that in order for a species of insect to develop resistance to an antibiotic, several generations have to pass, whereby genes from those that have some natural resistance pass them on to their offspring. But sometimes conventional wisdom fails to take into account how so... Read More
Prof. Pamela Ronald, a Professor in Plant Pathology at University of California, Davis and director of Grass Genetics at the Joint Bioenergy Institute, studies genes that control the plant response to stress.
In her presentation for the Frontiers in Life Sciences symposium at Cornell Universi... Read More
Bacillus is a video game named after the organism the developer studied in college. It's very different from other video games in that it features an accurate model for evolution. So accurate, every bacteria in the game has it's own genome (represented by A's T's C's and G's of course). But the ... Read More
The investigation of a mystery disease that has killed dozens of children in Cambodia is advancing after the discovery in patient samples of a virus that causes hand, foot and mouth disease.
The Institut Pasteur du Cambodge found enterovirus 71 in 15 of 24 patients sampled since mid-June, Phi... Read More
Kathleen Maguire, a Marlborough High School Senior, is presenting a poster at the American Society for Microbiology (ASM) Conference in San Francisco on June 16-19. In order to attend the conference, Maguire became a special member of the society. She is the first high school student to have a p... Read More
Some viruses that infect bacteria (bacteriophages) deliver their DNA into the host cell with an amazing injection machine. The tailed bacteriophages (such as T4, illustrated) store their DNA in a capsid attached to a long tail tube that is surrounded by a sheath. At the bottom of the tube is a b... Read More
We’ve all heard the claims of probiotic yogurts and their benefits for human health, but aside from improving our belly dancing skills, what exactly are probiotic bacteria doing?
An elegant study from the Jeffrey Gordon lab explored the effects of consuming fermented milk products (FMPs) cont... Read More
As part of The Ungovernables' exhibition, The New Museum hosted The House of Natural Fiber (HONF), a new media art collective out of Yogyakarta, Indonesia. Yogyakarta is the second largest city on Java, a densely-populated island that hosts an active volcano named Mt. Merapi which erupted in 200... Read More
Researchers at Moffitt Cancer Center and colleagues at the University of South Florida have discovered a mechanism that explains how some cancer cells “hijack” a biological process to potentially activate cell growth and the survival of cancer gene expression.
Their study appeared in a recen... Read More
The research findings, published this week in two papers in the journal Science provide new insights into the behavior of bacteria.
International collaborative research by Trinity College Dublin geneticists has established a blueprint as to how bacteria respond to environmental and nutritiona... Read More
In less than 30 years, there may be nothing left of the Titanic but a heap of “rusticles,” warns researcher Henrietta Mann, who has spent four years researching bacteria gnawing on its sunken hull.
A scientific expedition in 1991 to the disintegrating wreck some 12,400 feet (3,780 meters) to ... Read More
Food safety officials are investigating whether raw fish in sushi and other foods is responsible for a multi-state Salmonella outbreak that has sickened eight people in Illinois.
So far, no deaths have been connected to the strain of the bacteria, which has sent 10 people to the hospital and ... Read More
Fiber supplements may help the body’s own killer cells fight bacterial infection and reduce inflammation, greatly decreasing the risk of colon cancer.
Prebiotics are fiber supplements that serve as food for the trillions of tiny bacteria living in the gut. When taken, they can stimulate the g... Read More
A newly added session at the 2012 General Meeting of the American Society for Microbiology will focus on the latest data release by the NIH Human Microbiome Project (HMP).
The HMP has been a five-year endeavor to produce community resources to support the human microbiome field. These activit... Read More
Salmonella enterica is a leading cause of diarrhea illness worldwide, according to Sadhana Ravishankar, an assistant professor in the University of Arizona department of veterinary science and microbiology.
Each year the tiny, rod-shaped species of bacteria with a love for rapid reproduction ... Read More
In 1969 David Baltimore proposed that poliovirus RNA replication is coupled with packaging, in that only those genomes actively replicating will be selectively encapsidated. From an evolutionary standpoint, it is an ingenious requirement to ensure that only virus genomes capable of replication ... Read More
The next new acne treatment may be found in the produce section of your food store.
Largely due to its anti-inflammatory and anti-bacterial properties, the herb thyme -- which is found with other herbs in the produce section of most food stores -- may well earn itself a place in the skin care... Read More
At first glance, the inaugural 1812 issue of the New England Journal of Medicine and Surgery, and the Collateral Branches of Science seems reassuringly familiar: a review of angina pectoris, articles on infant diarrhea and burns. The apparent similarity to today's Journal, however, obscures a fu... Read More
Infectious-disease doctors have proposed a speedier, easier approval process for drug companies developing antibiotics against untreatable illnesses.
The Infectious Diseases Society of America (IDSA) made the proposal today at a hearing of a subcommittee of the US House of Representatives Com... Read More
