Federal health officials recommended Wednesday that hundreds of thousands of Americans at risk for AIDS take a daily pill that has been shown to prevent infection with the virus that causes it.
If broadly followed, the advice could transform AIDS prevention in the United States — from relianc... Read More
By shifting evolution into reverse, it may be possible to use “green chemistry” to make a number of costly synthetic drugs as easily and cheaply as brewing beer. Normally, both evolution and synthetic chemistry proceed from the simple to the complex. Small molecules are combined and modified to ... Read More
Researchers have developed a high-tech method to rid the body of infections — even those caused by unknown pathogens. A device inspired by the spleen can quickly clean blood of everything from Escherichia coli to Ebola, researchers report on September 14 in Nature Medicine.
Blood infections c... Read More
The CHILD-INNOVAC European research programme, coordinated by Inserm, has enabled the development of an innovative vaccine that can be administered intranasally, to combat pertussis, which has shown a resurgence in developed countries in recent years. The research consortium, headed by Camille L... Read More
Alberta health officials have confirmed an isolated, fatal case of H5N1 or avian influenza, federal Health Minister Rona Ambrose said Wednesday.
But officials repeatedly emphasized that there is no risk of transmission between humans.
The infected person, an Alberta resident who recently ... Read More
A nanoparticle wrapped in material taken from the membranes of red blood cells could become the basis for vaccines against a range of infectious bacteria, including MRSA (methicillin-resistant Staphylococcus aureus), an infection that kills tens of thousands of people every year.

The common cold virus (rhinovirus) is a tiny, almost round particle, containing the tightly packed genetic material surrounded by a protein shell (the virus capsid). Details on how the RNA is prepped to exit the capsid and effectively infect us have now been provided by scientists from the Max F... Read More
Family gatherings helped spread influenza during the 2013 holiday season, as the pace of flu reports jumped at year end, according to the U.S. Centers for Disease Control and Prevention.
About 4.3 percent of doctor visits during the week ended Dec. 28 were for complaints of flu-like symptoms ... Read More
AUSTIN, Texas — Microscopic fungi that live in plants' roots play a major role in the storage and release of carbon from the soil into the atmosphere, according to a University of Texas at Austin researcher and his colleagues at Boston University and the Smithsonian Tropical Research Institute. ...

Since the worst Ebola outbreak on record ignited last December in West Africa, scientists have been racing to develop drugs and vaccines to combat the virus. Several experimental drugs have been given to patients, and a new study details how scientists think one of those drugs might neutralize t... Read More
Much like how a snowplow is needed to clear streets of heavy snow, cells employ a set of genes to clear away misfolded proteins, to prevent them from accumulating and destroying the cell.
For the first time, Cornell researchers have demonstrated how a gene called SEL1L plays a critical role i... Read More
Mexico is considered one of the leading countries in papaya productions, but its crops are usually affected by the virus of the ringed spot, which leaves ring marks in the skin of the fruit and causes softening of the papaya, where fungi start to digest it. This is why the Center of Research and... Read More
To enter into symbiosis with nitrogen-fixing bacteria, host plants reprogram their root cells. An LMU team has now identified a calcium-binding protein complex that can be persuaded to spontaneously induce the formation of root nodules.
In almost all ecosystems, plant growth rates are limited... Read More
This week a study published in the British Medical Journal, and reported in the Daily Mail, has reported that a strain of bacteria known as Lactobacillus reuteri DSM 17938 is not effective in helping to reduce symptoms of colic in babies.
However here we examine the nature of the study, and i... Read More
The nucleoside adenosine—a tiny chemical structure made up of a simple base linked to a sugar—is critical for the regulation of bodily functions ranging from blood flow to tissue repair to sleep. Now, researchers at Rutgers New Jersey Medical School show that adenosine is essential in promoti... Read More
Recording together for the first time, the TWiV team celebrates their 300th recording at the American Society for Microbiology headquarters in Washington, DC, where Vincent speaks with Dickson, Alan, Rich, and Kathy about their careers in science.

Antibiotic stewardship programs, which promote the appropriate use of antibiotics in hospitals and other healthcare centers, can not only lead to reduction in antibiotic use with no adverse effects but can also lead to significant savings, over $600,000 annually in the case of one New York Ho...

It's not a secret that the microbes living in our guts play a huge role in our well-being, or that, at least in the United States, we're doing a good job of killing them off.
But now new research finds that apes -- our closest relative -- have much more varied gut flora than humans do, and es... Read More
Invasive species aren’t just species—they can also be pathogens. Such is the case with the West Nile virus. A mosquito-borne virus identified in the West Nile subregion in Uganda in 1937—hence the name—West Nile wasn’t much of a concern to people elsewhere until it broke out of Africa in 1999. T...

Exciting research suggests that a shot every one to three months may someday give an alternative to the daily pills that some people take now to cut their risk of getting HIV. The experimental drug has only been tested for prevention in monkeys, but it completely protected them from infection in... Read More
