The scariest thing about a shark's mouth — aside from the teeth — is the bacteria.
"It's a really dirty bite," said Dr. Robert Borrego, medical director of the St. Mary's trauma center in West Palm Beach, which has treated several shark-bite victims. "Some of them get infected.''

The spring semester has begun at Columbia University, which means that it is time to teach my virology course. The fourth annual installment of my virology course, Biology W3310, has begun. This course, which I taught for the first time in 2009, is intended for advanced undergraduates and conven... Read More
When you get the flu, viruses turn your cells into tiny factories that help spread the disease. In this animation, NPR's Robert Krulwich and medical animator David Bolinsky explain how a flu virus can trick a single cell into making a million more viruses.

Two studies of malnourished children offer the first major new scientific findings in a decade about the causes and treatment of severe malnutrition, which affects more than 20 million children around the world and contributes to the deaths of more than a million a year. Merely giving children a... Read More
Aside from rising sea levels, many climate change models predict that in the future, the planet's temperature and weather will become increasingly erratic with wild, unpredictable storms and fluctuating conditions.
A new study from researchers at the University of Florida and Yale University ... Read More
Scientists at UCLA and Charles R. Drew University of Medicine and Science have discovered a possible method by which cancer cells and dying cells communicate with nearby normal nerve cells without being physically connected to them.
Dr. Keith Norris, senior author of the research and assistan... Read More
Applied to the hull of a ship like paint, a new material could shake off scum by moving in response to an electric current.
Bacterial buildup on ships increases drag and reduces the energy efficiency of the vessel, as well as blocking or clogging undersea sensors.
The material works by phy... Read More

Have you ever wondered how scientists extract DNA from an organism? All living organisms have DNA, which is short for deoxyribonucleic acid; it is basically the blueprint for everything that happens inside an organism’s cells. Overall, DNA tells an organism how ... Read More
New research in The FASEB Journal suggests that a network of steroid molecules found in the brain is disrupted during HIV infection, and treatment with the steroid DHEA-S prevents brain damage.
A team of scientists from Canada, Thailand and Morocco have found that DHEA-S may prevent neurocogn... Read More

A new study suggests that patients with influenza can emit small virus-containing particles into the surrounding air during routine patient care, potentially exposing health care providers to influenza. Published in The Journal of Infectious Diseases, the findings raise the possibility that curr... Read More
A rumbling tummy is our body's way of telling us "it's time for lunch." Likewise, bacteria need to know when it's time to eat.
Researchers at the Institute of Food Research on the Norwich Research Park have uncovered how the food-borne bacterial pathogen Campylobacter jejuni can change its sw... Read More
In a new study, iron-oxidizing microbes give fresh meaning to the phrase "living off the grid," and provide fresh hope as a potential biofuel.
Researchers at the University of Minnesota, St. Paul, have coaxed a species of bacteria into trading their usual diet of partially-oxidized iron for a... Read More
Not long ago, Elio said in this blog that predation, a major force in evolution, is somewhat neglected in microbiological circles. The full implications of predation are just beginning to be uncovered as more becomes known about the ecology, physiology, and genomics of predators against microbes... Read More
Multiple RNA sequences can code for the same amino acid, but differences in their respective "optimality" slow or accelerate protein translation. Stanford biologists find optimal and non-optimal codons are consistently associated with specific protein structures, suggesting that they influence t... Read More
Imagining tiny creatures infiltrating human brains is creepy enough. But Marion Vittecoq knows she has been invaded. Her inner companions may be just hanging out — or they may be subtly changing her personality, manipulating her behavior or altering her risk of disease. Yet she doesn’t sound par... Read More
El podcast del microbio Nº 378 summarize an article published in Nature communications by Ribeiro-Viana R et al. on the use of Virus-like glycodendrinanoparticles to block viral infection. El podcast del microbio Nº 3... Read More
Both Nature and the New York Times have weighed in on the resumption of influenza H5N1 research. In an editorial from 23 January 2013, Nature opines that “Experiments that make deadly pathogens more dangerous demand the utmost scrutiny”. They call for a quantitative risk-benefit analysis of H5N1... Read More
