New study reveals why some people may be immune to HIV-1

Natural genetic variation in a protective antiviral enzyme holds promise for new therapies.

Doctors have long been mystified as to why HIV-1 rapidly sickens some individuals, while in others the virus has difficulties gaining a foothold. Now, a study of genetic variation in HIV-1 and in the c... Read More

How vultures evolved to live on rotting, feces-covered meat (and what we can learn from them)

Have you thanked a vulture today? It turns out that they're getting rid of an awful lot of dangerous bacteria for us. According to new research published Tuesday in Nature Communications, the vulture has a gut designed to kill off the bacteria that thrive on the carrion they crave. When they cho... Read More

Viruses as a Cure

When we talk about viruses, usually we focus on the suffering caused by Ebola, influenza and the like. But our bodies are home to trillions of viruses, and new research hints that some of them may actually be keeping us healthy.

“Viruses have gotten a bad rap,” said Ken Cadwell, an immunologi... Read More

Delaying ART in Patients with HIV Reduces Likelihood of Restoring CD4 Counts

A larger percentage of patients with human immunodeficiency virus (HIV) achieved normalization of CD4+ T-cell counts when they started antiretroviral therapy (ART) within 12 months of the estimated dates of seroconversion (EDS) rather than later, according to a report published online by JAMA In...

Worse Than The Bite

City dwellers across the U.S. might agree on one common enemy: bedbugs. But hey, not to worry, right? "Bedbugs are not known to spread diseases, but bites can be very itchy and irritating." Or so says the New York City Department of Health. But that assertion may not be true. Because a new study... Read More

Why CRISPR Doesn't Work in E. coli

We received this query:

»I enjoyed the article on your blog 'Six Questions About CRISPRs' by Merry Youle. I am an ex-lambdologist, having quit phage lambda in the early 70s and moved to GM-plants. There is one thing about CRISPR that I do not understand: Why did lambdologists not find CRISPR?... Read More

Flu virus key machine: First complete view of structure revealed

Scientists looking to understand – and potentially thwart – the influenza virus now have a much more encompassing view, thanks to the first complete structure of one of the flu virus’ key machines. Knowing the structure allows researchers to finally understand how the machine works as a whole, a... Read More
