This research team is using directed evolution to develop strains of Pseudomonas aeruginosa that can chelate and remove heavy metal contaminants from the environment. They're trying to raise money directly from the public to support their research. If you want to participate in this project, at ... Read More
A simple, fast and inexpensive new test for leprosy offers hope that, even in the poorest countries, victims can be found and cured before they become permanently disabled or disfigured like the shunned lepers of yore.
American researchers developed the test, and Brazil’s drug-regulatory agen... Read More
Hepatitis C virus has evolved to invade and hijack the basic machinery of the human liver cell to ensure its survival and spread. Researchers at the University of North have discovered how hepatitis C binds with and repurposes a basic component of cellular metabolism known as a microRNA to help ... Read More
Odd-looking viruses are waging war on an ocean-living bacterium that’s key to the Earth’s carbon cycle, say researchers.
In one corner is the Earth’s most abundant organism: SAR11, an ocean-living bacterium that survives where most other cells would die and plays a major role in the planet’s... Read More

Though they can rapidly spread pathogens that afflict humans, bats somehow avoid getting sick from viruses like Ebola, SARS, and other deadly bugs. A new genetic analysis of two very different bat species shows how the animals avoid disease, and live exceptionally long lives.
The team seque... Read More
Bacteria that live almost a mile under the surface of the ocean, where light is scare, have adapted biological ways to harness tiny amounts of light very efficiently, and in some cases can use photosynthesis to convert 100 percent of the light they find into electricity. In contrast a typical so... Read More
The influenza virus can spread up to 6 feet from a patient's head via submicron particles during routine hospital care, according to a study of patients admitted to the emergency department (ED) and throughout a tertiary care hospital with influenza-like illness during the 2010 to 2011 influenza...

Choosing the perfect wine may soon involve more than just knowing the perfect vintage and chateau. Differences in the microbes present on grapes even in different parts of the same vineyard may contribute to flavor fluctuations in samples of grapes from different tanks, according to research pub...

Here's my summary of the second day of ASM2013, an exciting day full of science.
Tomorrow morning, the US Food and Drug Administration will consider whether to accept reauthorization of legislation that allows us to know a few details about how many antibiotics are sold each year for agricultural use.
The agency probably will accept the reauthorization, and you would thin... Read More
Unlike most organisms, they don't need iron, but they crave manganese. Scientists have confirmed that the pathogen that causes Lyme Disease—unlike any other known organism—can exist without iron, a metal that all other life needs to make proteins and enzymes. Instead of iron, the bacteria substi... Read More
Maryn McKenna summarizes what we know about the murder of six people working as polio vaccinators who were targeted in three separate coordinated attacks in Pakistan. This comes in the wake of the CIA ruse in 2011 who used an immunization campaign to find Osama Bin Laden. Read More
Multidrug-resistant bacteria remain a major concern for hospitals and nursing homes worldwide. Propagation of bacterial resistance is alarming and makes the search for new antimicrobials increasingly urgent. Scientists at the Max Planck Institute for Biophysical Chemistry in Göttingen have now i... Read More
Replacing missing gut bacteria in a mouse model of autism reverses adverse social behaviours and gut disorders associated with the condition.
Last year, Sarkis Mazmanian and Paul Patterson at the California Institute of Technology in Pasadena found that infecting pregnant mice with molecules ... Read More
Rare brain tumors found in raccoons in Northern California and Oregon may be linked to a new virus, according to a new study.
Researchers, led by scientists from the University of California, Davis, said their findings could shed light on how viruses cause cancer in both animals and humans.

These days we are constantly bombarded by commercial messages urging us to fight germs and rid ourselves of bacteria. But in the right places and amounts, bacteria are actually very valuable to our health and wellness. Under normal circumstances, friendly bacteria found in our digestive system l... Read More
