Cyanobacteria could serve as a synthetic biology chassis that could be retooled for the production of biofuels, drugs or chemcials. So far, however, they have been held back by sluggish growth that makes it difficult to conduct the initial experiments needed to characterize their genetic and met... Read More

More than 15 million people in the United States live with food allergies that impact every meal they eat. For some, accidentally ingesting a snack that their body deems taboo can ignite a violent biological response. Every three minutes someone is rushed to the emergency room due to a food alle...

In the largest longitudinal study of the microbiome to date, researchers from the Broad Institute of MIT and Harvard, Massachusetts General Hospital (MGH), and the DIABIMMUNE Study Group have identified a connection between changes in gut microbiota and the onset of type 1 diabetes (T1D). The st... Read More
Rivers and streams could be a major source of antibiotic resistance in the environment.
The discovery comes following a study on the Thames river by scientists at the University of Warwick’s School of Life Sciences and the University of Exeter Medical School.
The study found that greater n... Read More
Since the 1950s farmers have fed antibiotic growth promoters (AGPs) to livestock. Overusing these substances can create superbugs, pathogens that are resistant to multiple drugs and could be passed along to humans. Mindful of that, companies such as Perdue Farms have stopped using the drugs to m... Read More
Here’s an undeniable fact: In samples collected from seven of New York’s subway platforms, scientists discovered that we're surrounded in plumes of microbes wafting off other people’s skin. Here’s another undeniable fact: Those bacteria colonize all of our glands and follicles and the entire epi... Read More
For more than a year, Cornell University's Christopher Mason and his team of researchers have been identifying bacteria in the New York City subway system. And some of the findings might surprise you. Photo: Katie Orlinsky for The Wall Street Journal
According to the Review on Antimicrobial Resistance commissioned by the UK Prime Minister, failing to address the growing problem of drug-resistant infections could cause 10 million deaths a year and cost up to $100 trillion USD by 2050.
Now, researchers from the Hebrew University of Jerusal... Read More
A compound found in green tea may trigger a cycle that kills oral cancer cells while leaving healthy cells alone, according to Penn State food scientists. The research could lead to treatments for oral cancer, as well as other types of cancer.
Earlier studies had shown that epigallocatechin-3... Read More

The specific strain of HIV that a person first contracts can have a lasting impact on how the virus disrupts his or her immune system, say researchers.
“This may have important implications for cure strategies aimed at eliminating the viral reservoir, as individuals infected with low replicat... Read More
Bacteria may not have brains, but they do have memories, at least when it comes to viruses that attack them. Many bacteria have a molecular immune system which allows these microbes to capture and retain pieces of viral DNA that they have encountered in the past, in order to recognize and destro... Read More
