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
A drug candidate that has shown promise for neutralizing dangerous bacteria also prevents growth of the parasite that causes malaria, new research by a Yale University team headed by Nobel laureate Sidney Altman shows.
The compound created in the labs of Altman and co-senior author Choukri Be... Read More
Maggie Koerth-Baker over at Boing Boing dug up a great thread at Quora asking users to share their favorite iconic scientific photos. The page has grown into a beautiful collection of images ranging from Darwin's illustration of finch beak variations from the Galapagos Islands to the Hubble Deep... Read More
You’ve probably heard of "chickenpox parties," where parents get unvaccinated kids together (in the home of an infected child) in the hopes they'll catch the disease. They think making their kids suffer through the disease will help them develop stronger immunity than immunization would provide.... Read More
Reporting in the Proceedings of the National Academy of Sciences, a team of Jefferson immunologists found that a specialized "human immune system" mouse model closely mimics a person's specific response and resolution of a tick-borne infection known as relapsing fever, caused by the bacteria Bor...

Dear Dr. Racaniello
I was watching the conference in Dublin and I wanted to thank you for sharing my e-mail with the people in the panel, since I saw how nice it was for me to reach the specialists with that ease through TWIV.<... Read More
Scientists at the University of California, San Diego School of Medicine and Skaggs School of Pharmacy and Pharmaceutical Sciences have uncovered how the body's immune system launches its survival response to the notorious and deadly bacterium anthrax. The findings, reported online today and pub... Read More
Scientists from the Institute for Physical and Theoretical Chemistry at the University of Bonn have succeeded for the first time in the real time filming of the transport of an important information carrier in biological cells that is practically unmodified. This paper has now been published in ... Read More
Russian scientists have now poured 60 tonnes of freon and kerosene down the four-kilometre bore hole that plunges through the ice above Lake Vostok in Antarctica. This will stop the hole freezing up during the long Antarctic winter. When summer comes, the Russian team will return to drill the la... Read More
The fields of microbial symbiosis and speciation have achieved astonishing advances during the past two decades, yet symbiosis and speciation are not commonly discussed together and can seem to be odd partners in their capacity to operate synergistically in nature. Indeed, microbial symbiosis is... Read More
They live on your skin, up your nose, in your gut - enough bacteria, fungi and other microbes that collected together could weigh, amazingly, a few pounds.
Now scientists have mapped just which critters normally live in or on us and where, calculating that healthy people can share their bodi... Read More
Radio Mycelium proposes the construction of a series of experimental situations examining a new networked imaginary, the single organism of the fungal mycelium, in relation to pathogenic, electromagnetic communications. Participants will learn how to construct simple measurement devices, and cul... Read More
One of my heroes, evolutionary microbiologist Lynn Margulis, died this past Thanksgiving. She was an amazing lady who was married to Carl Sagan for many years, and partnered with James Lovelock in discovering that the earth is an interconnected living global ecosystem run largely by microbes. Sh... Read More
Regular use of fluoride-containing toothpaste and mouthwash has long been known to strengthen the enamel on teeth. But new research by Howard Hughes Medical Institute (HHMI) scientists finds that fluoride also has dramatic effects on bacteria inside the mouth -- including those that form plaque ... Read More
As we enjoy our most food-oriented holiday tomorrow, nutritionists and food safety experts recommend that particular care be taken to ensure that leftovers -- whether kept for later meals or dispatched home with guests -- don't become a catalyst for the pain, vomiting, and diarrhea that afflicts...

According to the New York Times (Why Science Majors Change Their Minds), the decline in the number of science majors in the United States has come about in part because the subject matter is too difficult. If this explanation is true, then we have not properly prepared these students in grades K... Read More
People who harbor ulcer-causing bacteria in their stomachs may be protected against some diarrheal diseases, suggests a new study.
The bacterium, called Helicobacter pylori, is especially common throughout the developing world, but only causes symptoms in a minority of those it infects.
Pe... Read More
Biology researchers discover that bacteria living in mosses on tree branches twice as effective at 'fixing' nitrogen as those on the ground. A new study by Dr. Zoë Lindo, a post-doctoral fellow in the Department of Biology at McGill University, and Jonathan Whiteley, a doctoral student in the sa... Read More
When Contagion hit the theaters on September 9, I was skeptical but interested (call it professional curiosity) to see Hollywood's latest attempt at showing microbial disaster. This time, director Steven Soderbergh sought help from an actual virus hunter, W. Ian Lipkin, a professor of epidemiolo... Read More
