Your body clock may play a role in fighting off bacterial infections in the gut, according to a new study in animals.
Researchers said the findings could help explain why people who have disruptions in their circadian rhythm -- like those who fly across time zones frequently, or shift workers... Read More
Over the past year, two experienced biologists at Oslo University have seen something that very few scientists experience. They have been sought out by a persistent stream of people from all over Norway who are asking for help.
"People so sick that they can barely stand up have come here to K... Read More
(op-ed article) There is a new and deadly threat making its round in Saudi Arabia. It is the Mers, or the Middle East Respiratory Syndrome Coronavirus and what makes this virus an ominous threat is that the majority of those who had contracted the disease died from it.
Saudi Arabia seems to b... Read More
Bacteria are single celled organisms that can do amazing things in multicellular groups, with complex coordinated behaviors emerging from the interaction of genetic networks, chemical environments, and the physics of cell growth. Last year I wrote about the work of Tim Rudge and Fernan Federici ... Read More
The bacteria that live in the human gut may play an important role in immune response to vaccines and infection by wild-type enteric organisms, according to two recent studies resulting from a collaborative effort between the University of Maryland School of Medicine Institute for Genome Science...

Wolbachia are intracellular bacteria that infect invertebrates at pandemic levels, including insects that cause such devastating diseases as Dengue fever, West Nile virus, and malaria. While Wolbachia-based technologies are emerging as promising tools for the control of the insect vectors of the... Read More
The Food and Drug Administration has found bacteria and fungus in vials of pain shots made by a Tennessee pharmacy whose products have been linked to infections.
FDA said it found the contaminants in two sealed vials of steroids made by Main Street Family Pharmacy, which has recalled all its ... Read More
Here's my summary of the second day of ASM2013, an exciting day full of science.
For fours years I have taught a virology course at Columbia University and have posted videos of each lecture on my website, virology.ws, and at iTunes University. Nearly 100,000 individuals have subscribed to my virology course at iTunes University. Now Columbia has signed an agreement with Cou... Read More
Bird flu viruses are potentially highly lethal and pose a global threat, but relatively little is known about why certain strains spread more easily to humans than others. Two studies published by Cell Press June 6th in the journal Cell identify mutations that increase the infectivity of H5N1 an... Read More
Bioengineers at the University of California, San Diego have developed a computational model of 1,366 genes in E. coli that includes 3D protein structures and has enabled them to compute the temperature sensitivity of the bacterium's proteins. The study, published June 7 in the journal Science, ... Read More
Miravirsen is a drug that binds to and blocks the function of a cellular microRNA called miR-122 that is required for the replication of hepatitis C virus (HCV). Treatment of chimpanzees chronically infected with HCV with this drug leads to suppression of viral replication. The results of a phas... Read More

French scientist Francoise Barre-Sinoussi almost didn't get the chance to make one of the greatest medical discoveries of the 20th century.
She shared the 2008 Nobel Prize in Physiology or Medicine with her colleague Luc Montagnier for identifying HIV, the virus that causes AIDS, a plague tha... Read More
The Polio virus has been found in a sewage sample from Israel for the first time since 2002, the World Health Organization announced on Monday. But no children or adults newly paralyzed by polio have been identified in Israel or in Gaza or the West Bank.
The sample was from Rahat, a city in t... Read More
