Biofuel producer Solazyme delivered 1,500 gallons of its algae-based jet fuel to the U.S. Navy’s testing and certification program today, helping the military reach its goal of switching half of its fleet to clean fuel by 2020. The Navy will use the fuel to power jets.
Solazyme produces fuel ... Read More
A new vaccine-delivery patch based on hundreds of microscopic needles that dissolve into the skin could allow persons without medical training to painlessly administer vaccines – while providing improved immunization against diseases such as influenza. Read More
A new way of surveying microbes for the metals they contain reveals that biologists have been relying on the equivalent of a 15th century map of the world. Read More

Revealing the science behind the homespun advice, a team of researchers at Worcester Polytechnic Institute (WPI) has identified and measured the molecular forces that enable cranberry juice to fight off urinary tract infections in people.
The data is reported in a paper published in the journ... Read More
Scientists in the US who developed a skin patch that uses hundreds of microscopic dissolvable needles to deliver vaccine into the body have shown it works on animals, perhaps even better than the traditional injection method; they envisage that one day this approach could reduce the cost and adm...

Football players usually worry about wrecked knees, torn hamstrings and concussions. Not staph infections.
"I never think about it," said Green Bay Packers cornerback Tramon Williams. "I don't even know anything about that."
Red Batty would like to keep it that way.
The Packers equipmen... Read More
More than half a century ago, when antibiotics were transforming modern medicine, a now almost forgotten drug was hailed as something close to the miracle of miracles. Doctors rushed to prescribe it for an array of medical problems — that is, until they discovered that the drug, chloramphenicol,... Read More
An international team of researchers has devised a technique to study how ocean-dwelling microbes respond to a compound that signals good foraging patches for fish and mammals, but also contributes to cloud-forming sulfur aerosols. The research offers further insight into the chemical ecology of... Read More
Using ever-growing genome data, scientists with the Department of Energy's (DOE) Oak Ridge National Laboratory and the University of Tennessee are tracing the evolution of the bacterial regulatory system that controls cellular motility, potentially giving researchers a method for predicting impo...

Hello Professor Racaniello,
We are two graduate students from the University of Guelph in Canada studying oncogenic sheep betaretroviruses and we are big fans of the show. Part of the reason we like the show so much is that we can use ... Read More
On episode #91 of the podcast This Week in Virology, Vincent, Dickson, Alan, Rich and Welkin discuss the nature, origin, and evolution of endogenous retroviruses (ERVs), and the recent finding of en... Read More
The bursts of rainbow colors in this photograph are mesmerizing, yet microbes are fighting for their lives in the background. Michael P. Zach of the University of Wisconsin-Stevens Point, snapped this image of a salt sample he collected in a hot, arid valley near Death Valley National Park in Ca... Read More

On May 25th, 2010 science writer Carl Zimmer gave a keynote address at the American Society for Microbiology's General Meeting in San Diego, California. The presentation entitled “Newspapers, Blogs, and Other Vectors: Infecting Minds with ... Read More
An update now on a story we're been following closely about a health risk most people don't know about - farmers feeding antibiotics to healthy animals - just to spur their growth. Congress urged them this week to stop doing that because overuse of antibiotics in animals is creating new, drug-re... Read More
A parasite afflicting nearly 12 million people across the world relies on a family of genes that should make it vulnerable to compounds developed to treat cancer and other disorders, new research by scientists at Washington University School of Medicine in St. Louis reveals.
The study appear... Read More
A two-step flu vaccine using DNA to "prime" the immune system and then a traditional seasonal influenza vaccine may be able to protect against all strains of the virus -- providing a long-sought "universal" flu vaccine, U.S. researchers said on Thursday.
The team at the National Institute of ... Read More
Methane seeps, which play a role in the global dynamics of this potent greenhouse gas, may be even more complicated than we thought. A perspective in this week's Science describes several new research papers on the release of methane at the level of the ocean floor. Their conclusions run counter... Read More
