Adding prebiotic ingredients to infant formula helps colonize the newborn's gut with a stable population of beneficial bacteria, and probiotics enhance immunity in formula-fed infants, two University of Illinois studies report.
"The beneficial bacteria that live in a baby's intestine are all-... Read More
One in every six cancers worldwide is caused by an infection that is preventable or treatable, according to new estimates published in the journal Lancet Oncology. The research indicates infections are attributable for approximately 2 million new cancer cases every year.

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
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
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
It’s become a sad fact that many people being treated in health-care facilities end up catching a bad -- and potentially deadly -- bug in the very place where they’re supposed to get better.
A report on the increased incidence of clostridium difficile infections in hospitals and other health-... Read More
Hello Vincent and Team TWIV,
I love Virology, and it is with much chagrin that I admit I have only recently started listening to TWIV. However I have tried to mend the error of my ways by: 1) proselytizing the benefits (keeping up-to-date with and... 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
To our TWIV leaders!
If you have a mac with Apps, please go to the app store and download cell images.... I think you'll have a great time going through them.
One other thing - I listened to your show on science reform with interest but I ... 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
