A new study in the Netherlands has found a deep-sea microbe living in high-temperature hydro-thermal vents can thrive on chlorate and perchlorate anions. Perchlorate, an ingredient in rocket fuel and fireworks, is toxic to most organisms.
The researchers, led by Martin Liebensteiner of Wageni... Read More
Bloodstream infections cut by more than 40 percent in study of over 74,000 patients. Using germ-killing soap and ointment on all intensive-care unit (ICU) patients can reduce bloodstream infections by up to 44 percent and significantly reduce the presence of methicillin-resistant Staphylococcus ...

18th International Bioinformatics Workshop on Virus Evolution and Molecular Epidemiology
VEME 2013 will be organized August 25th – August 30th, 2013 at the University of Florida in Gainesville, Florida, U.S.A.
The workshop will have the following modules:
• 'Phylogene... 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
Using the same strategy that a common virus employs to evade the human immune system, researchers at Wake Forest Baptist Medical Center's Institute for Regenerative Medicine have modified adult stem cells to increase their survival -- with the goal of giving the cells time to exert their natural...

Another major goal of synthetic biology is to engineer unnatural molecules and compounds into systems and tools that mimic those found in biology. For instance, Joanna Aizenberg and her laboratory have pioneered using self-assembling synthetic nanofibers to generate capture-and-release devices t... Read More
DNA preserved in calcified bacteria on the teeth of ancient human skeletons has shed light on the health consequences of the evolving diet and behaviour from the Stone Age to the modern day.
The ancient genetic record reveals the negative changes in oral bacteria brought about by the dietary ... Read More
Great HAI work! I'm not through it yet. I want to question, though, whether fomites are really important in influenza transmission. I don't think so.
[flu can transmit by fomites in guinea pigs: Read More
Scientists have revealed how a bacterial enzyme has evolved an energy-efficient method to move long distances along DNA. The findings, published in Science, present further insight into the coupling of chemical and mechanical energy by a class of enzymes called helicases, a widely-distributed gr... Read More
The cellular interior is criss-crossed by protein-based cables known as microtubules, each formed from 13 'protofilaments' composed of the protein tubulin. Microtubules are also associated with a host of other specialized proteins that help coordinate the transport of molecular cargoes and link ... Read More
Back when the Time Lord and I were still engaged, we went shopping for wedding rings. He only had one criteria: he wanted his ring to be made of platinum or a similar material forged in a supernova. It’s not quite as exotic as it sounds: most heavy elements were formed in supernovae, via a proce... Read More
Over the past 30 years, the combined efforts of scientists and clinicians have delivered remarkable successes in HIV therapeutics. Since 1987, the FDA has approved more than 30 antiviral drugs, including 12 HIV protease inhibitors and one integrase inhibitor. These drugs stop ~99% of viral repli... Read More
For the first time, researchers have found a particular kind of molecular switch in the food poisoning bacteria Salmonella Typhimurium under infection-like conditions. This switch, using a process called S-thiolation, appears to be used by the bacteria to respond to changes in the environment du... Read More
When you're hard drive fails, you order a new one online and then swap it out. Why can't we do that for biological parts as well? From DNA robots and "organs-on-a-chip" to nanobristles that grab-and-release drugs, this slideshow explores the two major goals of synthetic biology: to build new bio... Read More
A top New York chef teams up with Harvard scientists to explore the role of bacteria in fermentation. He hopes to better understand and tweak the process to create new and unique flavors to entice the palate. Sharon Reich reports. Read More
Food microbiology laboratories continue to submit false negative results and false positive results on a routine basis. A retrospective study of nearly 40,000 proficiency test results over the past 14 years, presented today at the 113th General Meeting of the American Society for Microbiology, ... Read More
In this blog post, I show how students in my freshman "introduction to cell and molecular biology" course used "creativity"-based approaches to better understand concepts in the course---as they prepare for their upcoming final exam. I believe that this kind of approach truly helps with student... Read More
The proportion of young women diagnosed with genital warts in Australia has seen a significant decline thanks to the HPV vaccine, suggests a new paper. In 2007, Australia became one of the first countries to implement a nationally funded quadrivalent human papillomarivus (HPV) vaccination progra... Read More
In the latest of a slew of studies examining the role of the so-called microbiome -- the mix of microscopic critters that colonize our bodies and our environment -- in human health, Harvard researchers said Wednesday that part of the reason that Roux-en-Y gastric bypass surgery works so well in ...
