The University of California-Berkeley is incorporating volunteers to help pinpoint the flash points of sudden oak death syndrome.
"The furtive, runaway disease earned its name by killing oaks from the inside. After about a year, infected oaks succumb to the disease. Sudden oak disease has ki... Read More
Scientists have created a new antimicrobial paint kills disease-causing bacteria, mold, fungi and viruses. Apparently it can be "recharged" using a simple chlorination process.
"The paint contains a new antimicrobial polymer with a type of N-halamine, a bleach-like substance that kills germs.... Read More
It was the first underground movement in our planet's history: Primitive bacteria that lived 2.75 billion years ago built themselves caves to live in, according to a new study. Today, the traces they left behind are stoking hopes that similar life forms could exist on Mars.
Early Earth was a ... Read More
The oceans still contain mysteries with the potential to help humanity. For example, scientists have discovered a sea sponge they say could help fight antibiotic-resistant bacteria.
Peter Moeller: What we found was a sponge growing in a pristine state. It was thriving in an environment that w... Read More
Health officials worldwide have a watchful eye on the Southern Hemisphere, where flu season is about to begin. How H1N1 circulates there may determine how aggressively U.S. health officials approach the flu in the fall.
Although it is far from certain that a vaccine for the bug often called s... Read More
In resource-limited countries, a lack of training, proper reagents, supplies, and equipment has impacted their laboratories' ability to identify key pathogenic bacteria and detection of antimicrobial resistance. This has led to an environment of syndromic diagnosis by clinicians who have little ... Read More
Somewhere out there, somewhere along the way, a single creature got all this started. A pig, presumably. Pig Zero.
Scientists suspect that two influenza viruses common in swine, one rooted in Eurasia and the other in North America, came together in a single cell within a pig. The two viruses ... Read More

Bacteria in the gut of the Anopheles gambiae mosquito inhibit infection of the insect with Plasmodium falciparum, the parasite that causes malaria in humans, according to researchers at the Johns Hopkins Bloomberg School of Public Health. Scientists with the Bloomberg School’s Malaria Research I... Read More
San Diego was one of the primary regions of the H1N1 outbreak, inducing a lot of public anxiety and media coverage. They had a confirmed case of H1N1 on our campus and their child care center closed down because on the number of kids with flu-like

Why is the immune system able to fight off some viruses but not others, leading to chronic, life-threatening infections like HIV and hepatitis C?
A new UCLA AIDS Institute study suggests the answer lies in a protein called interleukin-21 (IL-21), a powerful molecule released by immune cells d... Read More
A team of chemists from the University of Almería (UAL) has developed a method to simultaneously detect the presence of 17 antibiotics in honey within less than 10 minutes. The researchers have shown that traces of antibiotics used to treat diseases among bees can be found in some commercial hon... Read More
The title pretty much sums up the main thrust of the post, which also includes section on cheap, rapid diagnostic tests that not only can identify known pathogens, but provide quite a bit of information about novel pathogens (link to a great Pop!Tech video lecture by Ian LIpkin). There's also a ... Read More
Over at the World's Fair Science blog David Ng has come up with this song about mitochondria.
It sort of reminds me of a Social Distortion song. Read More
Wow, the NEJM is really knocking out some great "perspectives" in their most recent issue.
The Internet has become a critical medium for clinicians, public health practitioners, and laypeople seeking health information. Data about diseases and outbreaks are disseminated not only through onli... Read More
The air smells cleaner in Canda thanks to thanks to University of Alberta researchers who have developed a formula to reduce methane gas in cattle.
By developing equations that balance starch, sugar, cellulose, ash, fat and other elements of feed, a Canada-wide team of scientists has given be... Read More
Bird flu kills more than 60 percent of its human victims, but doesn't easily pass from person to person. Swine flu can be spread with a sneeze or handshake, but kills only a small fraction of the people it infects.
So what happens if they mix?
This is the scenario that has some scientists ... Read More
