The same bacteria that eats flesh can make a super glue used to bind molecules.
Dr. Mark Howarth, with his graduate student Bijan Zakeri in Oxford University's department of biochemistry, developed an adhesive that sticks molecules together, nearly inseparably.
They used the bacteria Strep... Read More
Two papers published this week, and one last month, reveal the pandemic potential of H5N1 "bird flu". One identifies four, another identifies five, genetic changes the virus would have to undergo before it could spread easily in humans, and the third paper suggests some of these changes are alre...

A bacterium found in soil is a showing promise as a way of delivering cancer drugs into tumours.
Spores of the Clostridium sporogenes bacterium can grow within tumours because there is no oxygen.
UK and Dutch scientists have been able to genetically engineer an enzyme into the bacteria to ... Read More
A bacteria strain that causes a hard-to-treat staph infection probably developed its antibiotic resistance in food animals, a team of scientists announced Tuesday.
The strain of staph, known as methicillin-resistant Staphylococcus aureus, or MRSA CC398, most often infects farm workers who com... Read More
Bacteria found in gold mines and frozen caves show the extreme flexibility of life, and hint at where else we might find it in the solar system.
The first time Tullis Onstott ventured underground, he squeezed into an elevator with dozens of South African gold miners and descended a mile into ... Read More

Vince, here is the text of my post on Peter S site. I was disappointed in the quality of his article as I have much previous experience with his work and see him as the "David Baltimore of Risk Communication". If you could get him on as a guest you would e... Read More
Dear TWiM Team
A fascinating article from New Scientist this week.
Standard medical teaching is that the foetus is sterile and that the microbiome only begins to develop post natal.
New research from Spain indicates that the microbiome s... Read More
Dictyostelium discoideum is a soil-living amoeba. A group of 100,000 form a mound as big as a grain of sand.
The hereditary information is carried on six chromosomes with sizes ranging from 4 to 7 Mb resulting in a total of about 34 Mb of DNA, a multicopy 90 kb extrachromosomal element that h... 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.
"Infections with cert... Read More

Learn about the bacteria, fungi and other micro-organisms that maintain human health.
The body contains 10 times more bacteria, fungi and other micro-organisms than human cells. Most of these species are harmless—although they can still cause illness if they wind up in the wrong place. In add... Read More
If we can visualize a protein's shape, we can learn much more about how it functions and how we might block its activity. This was the guiding principle behind an NIH initiative launched 25 years ago to spur the discovery of HIV-related protein structures. Structures produced through the program... Read More

Influenza A virus reservoirs in animals have provided novel genetic elements leading to the emergence of global pandemics in humans. Most influenza A viruses circulate in waterfowl, but those that infect mammalian hosts are thought to pose the greatest risk for zoonotic spread to humans and the ... Read More
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.

Imagine you are a tiny caddisfly pupa. When you emerge from your pupal case, it is dark, but not pitch black, and high above you, you see the faint glow of a starry sky. On new wings, you rise. Cue angelic voices.
Suddenly, you struggle against an invisible barrier. Cue scary cello. You begin... Read More
