This is a database of Herpes simplex (HSV-1) host/viral interactions hosted at WikiGenes. It provides a global snapshot of what the virus does in different compartments at all stages of the viral life-cycle from entry to exit. The database is interactive, and any researcher can edit the page or ... Read More
The genetic make-up of pathogenic bacteria and their harmless cousins is much more similar than previously thought, UA microbiologists find.
In the bacterial world, good guys can potentially turn into bad guys and vice versa - just by swapping genes, microbiologists at the University of Arizo... Read More

Children exposed to PCBs in their first years of life are less likely to develop immunity to disease after they are vaccinated, according to a new study. Overall, the study shows that cumulative exposure to environmental PCBs – particularly leading up to 18 months of age – may decrease immune sy... Read More
The short answer is four hours, but there's a lot more to it than that.
Avoiding food poisoning is complex (the p.c. term now is "foodborne illness," lest we start tainting the deli guy as a "poisoner"), but it can be largely boiled down to a few key points about how bacteria grow, taught to ... Read More
Is a trip to the beach in your weekend plans? Two recent studies suggest that illness-causing bacteria could be hiding in the water.
A University of Miami study found that beach goers who swam at a South Florida beach were at higher risk of sickness in the week after their visit compared to p... Read More
Family meals often descend into ritual battles over healthy greens: how many children must consume, and how many treats they will earn as a result. The stakes may be higher than parents realise. According to a study published this week in Proceedings of the National Academy of Sciences, a sugary... Read More
This blog is the modern version of a field journal, a place for reports on the daily progress of scientific expeditions — adventures, misadventures, discoveries. As with the expeditions themselves, you never know what you will find:
Monday, Aug. 2
At 7:45 this morning, Alvin emerged from i... Read More
The XMRV retrovirus has been implicated in chronic fatigue syndrome and prostate cancer. A homology search comparing retroviral with human proteins revealed short contiguous amino acid strings (typically 5-8 aa) matching human proteins whose dysfunction might be expected to cause fatigue, includ...

If you trawl a net through the ocean's depths, chances are just about every living thing you haul to the surface will be able to glow. Marine biologists estimate that between 80 and 90 percent of deep-sea creatures are bioluminescent—they produce light through chemical processes.
Like the dee... Read More
HIV-AIDS. SARS. Ebola. Bird Flu. Swine Flu. Rabies. These are emerging infectious diseases where the viruses have jumped from one animal species into another and now infect humans. This is a phenomenon known as cross-species transmission (CST) and scientists are working to determine what drives ... Read More

A DNA sequence-based system to better define when a pathogen or toxin is subject to Select Agent regulations could be developed, says a new report from the National Research Council, which adds that this could be coupled with a "yellow flag" system that would recognize requests to synthesize sus...

Nottingham Trent University (NTU) has developed a method of making very small particles of gold with an antibiotic shown to neutralise dangerous bacteria such as Escherichia Coli (E Coli).
The findings - published in the Journal of Materials Chemistry - explain how the team at Nottingham has ... Read More

Prairie dogs, once abundant in the Rocky Mountains and Great Plains, have been decimated in recent decades by plague -- a virulent bacterial disease spread by fleas.
Plague outbreaks periodically sweep through large prairie dog towns with thousands of inhabitants, killing virtually the entire... Read More
GlaxoSmithKline PLC (GSK) Wednesday said a method of killing bacteria already resistant to existing treatments has been found which could help scientists develop new antibiotics to tackle bacteria responsible for many hospital and community-acquired infections.
The research results, published... Read More
Hematopoietic stem cells provide the body with a constant supply of blood cells, including the red blood cells that deliver oxygen and the white blood cells that make up the immune system. Hematopoietic - or blood - stem cells must also make more copies of themselves to ensure that they are pres... Read More
Dengue update from around the world compiled from various news sources:
An alert has been sounded in the city to control the spread of dengue. With the Commonwealth Games round the corner and the fear of a dengue epidemic looming large, the Municipal Corporation of Delhi (MCD) has said it wil... Read More
On Wednesday, a report released by the National Oceanic and Atmospheric Administration said early observations showed that the oil from the Deepwater Horizon spill “is biodegrading quickly,” adding that scientists were working to measure how quickly and how much of the escaped oil the microbial ...
