Bacteria can multiply rapidly, potentially doubling every 20 minutes in ideal conditions but this exponential growth phase is preceded by a period known as lag phase, where no increase in cell number is seen. Lag phase was first described in the 19th Century, and was assumed to be needed by bact... Read More
Scientists may have found one of the keys to weight loss hiding in the poop of 3,000-year-old mummies. The bacterial DNA found in their guts is very different from our modern intestinal flora.
The reason: chlorinated water and antibiotics.
That's the first hypothesis of Dr. Cecil Lewis. Acco... Read More
Microbial inhabitants outnumber our body's own cells by about ten to one. These residents have become the subject of intensive research, which is beginning to elucidate their roles in health and disease.
Two journal articles by, David A. Relman, Departments of Medicine and of Microbiology and... Read More
If you've ever had a bacterial infection like staph or strep throat, your doctor may have prescribed penicillin. But if you've had the flu or a common cold virus, penicillin won't work. That's because antibacterials only kill bacteria, and both the flu and the common cold are viruses. So for ill... Read More
Researchers at the College of Life Sciences have identified fexinidazole as a possible, much-needed, new treatment for the parasitic disease visceral leishmaniasis.
Leishmaniasis is named after William Leishman, a Glasgwegian doctor serving with the British Army in India, who first identified... Read More
The latest episode of the Animal Science Podcast from the American Society of Animal Science interviews researcher Mark Westhusin at Texas A&M University which recently announced the birth of a genetically modified goat that produces a malaria vaccine in its milk. This goat could help people in ... 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
Water is set to use a new biological weapon to flush away Whitby residents’ festive fat.
Over the Christmas period trillions of fat-busting bugs have been deployed in the sewers of Whitby to feast on fat, oils and grease.
Over time these substances build up on the inside of sewer pipes, re... 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
An unusual regulatory mechanism that controls the swimmer/non-swimmer option in genetically identical Salmonella also impacts the bacteria's ability to cause infection.
University of Washington scientists reported the discovery this week in the Proceedings of the National Academy of Sciences.... Read More
When I drafted my article for TakePart (Don’t Panic – Ebola Isn’t Heading For You), I used the term ‘ebolavirus’ throughout, but the editors changed every instance to ‘Ebola virus’. Understanding which term is correct is far more complicated than you might imagine. Read More
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
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
A man can live many lives. Paul Ehrlich has. Once, he was a butterfly biologist. Another time, he wrote the book called The Population Bomb, a book that triggered global conversations about the fate of humanity. Still another, he described the relationship between plants and the animals that eat... 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
I listen to TWiM and perhaps this story (from mine ha!) will be of interests. A nicely written microbiology blog talking about two papers that use metagenomic sequencing on viruses in insect vectors: mosquitoes (animal viruses) and whitefly (plant viruses)
Not only did we find known human an... Read More
Ultraviolet rays help prevent the spread of chickenpox, meaning people in milder climates are more at risk of catching the disease, according to new research. The discovery could lead to new ways of preventing chickenpox and its more severe relative, shingles.
A researcher at St George’s, Uni... 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
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
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
