Some heavy metals share a long history with microbes. Many of the metabolic processes that sustain life are believed to have originated from spontaneous reactions involving metals present in the early Earth. Our microbial ancestors figured out quickly how to use those metal catalysts to generate... Read More
No admission for bacteria: Scientists from the University of Freiburg have succeeded in preventing Pseudomonas bacteria from entering host cells with the help of a sugar complex. Dr. Thorsten Eierhoff and junior professor Dr. Winfried Römer from the Institute of Biologie II, both members of the ... Read More
The Centers for Disease Control plans to take measures to better protect lab workers and the rest of us from dangerous biological samples.
Twenty-one dead lab chickens piled up this spring at a government facility before its researchers could pinpoint why. The team had requested and received ... Read More
The Human Microbiome Project (HMP) is a global initiative to identify and characterize the microorganisms present at multiple sites in the human body. An international team of researchers reports on new ways to harness the results of the HMP and discusses how changes in the microbiome might affe... Read More
The drought that has the entire country in its grip is affecting more than the color of people’s lawns. It may also be responsible for the proliferation of a heat-loving amoeba commonly found in warm freshwater bodies, such as lakes, rivers and hot springs, which the drought has made warmer than...

The technique addresses the problem of hidden reservoirs of HIV in the body, and could herald a new way of battling the viral infection.
Once HIV invades the body, it doesn’t want to leave. Every strategy that scientists have developed or are developing so far to fight the virus – from powerf... Read More
After studying 137 varieties of cheese collected in 10 different countries, researchers have been able to identify three general types of microbial communities that live on cheese, opening the door to using each as a 'model' community for the study of whether and how various microbes and fungi c...

A report in Biology Letters shows that the drool of herbivores might help defeat the toxic fungal defences of the plants they graze on.
Grazing or cutting some plants induces a noxious chemical to be produced which deters hungry plant-eaters from revisiting them. The chemicals, called alkaloi... Read More
Read about Angelina Fanny Hesse, an unsung heroine of microbiology who helped make the isolation of bacteria possible in this Popular Science blog post by Christina Agapakis:
"In the earliest days of microbiology, scientists were stumped about how to isolate bacteria. That is, until the fami... Read More
The symbiosis between some plant species and nitrogen-fixing nodule bacteria is one of the most relevant cooperative relationships in the world. It shapes our global vegetation and, not least, the global nitrogen and carbon cycle. The foundations for this process were probably laid in just one e... Read More
The TWiVome discusses an miRNA based strategy to mitigate risk of gain of function studies, and identification of a second receptor required for Lassa virus entry.
SDSU virologists and biologists have identified a highly abundant, never-before-described virus that could play a major role in obesity, diabetes.
Odds are, there’s a virus living inside your gut that has gone undetected by scientists for decades. A new study led by researchers at San Diego S... Read More
The road to finding a cure for HIV-1 is not without obstacles.
