In a fascinating story that was presented on NPR by Nell Greenfieldboyce we learn that the source of the Justian Plague (541-543AD) was recently identified by sequencing blood extracted from the dental pulp of the teeth associated with two skeletons recovered from Munich. For many years it was... Read More
Using two yeasts that have been used to brew tea and beer for centuries, researchers at Fred Hutchinson Cancer Research Center have revealed how reproductive barriers might rapidly arise to create species boundaries. Schizosaccharomyces pombe has been used to brew beer in Africa, whereas its clo... Read More
Today, President Obama signed an Executive Order directing key Federal departments and agencies to take action to combat the rise of antibiotic-resistant bacteria. The Administration also released its National Strategy on Combating Antibiotic-Resistant Bacteria. In addition, the President’s Cou... Read More
Prokaryotes are by far the most successful superkingdom in terms of both biochemical diversity and the variety of environments conquered. Bacteria can be found living in all kinds of adverse conditions; from high alkaline lakes, to below freezing temperature, to hot volcanic vents which in some ... Read More
Vanderbilt University researchers have now discovered how intestinal cells build this specialized structure, which is critical for absorbing nutrients and defending against pathogens. The findings, published April 10 in the journal Cell, reveal a role for adhesion molecules in brush border assem... Read More
Corralling desperados with names like bacillus and paenibacillus will require ingenuity and an arsenal of weapons. These outlaws aren't rustling cattle—they're making milk sour and cheese soft and crumbly.
For more than a century, milk has been heated to kill any bacteria or pathogens that ca... Read More
One way to avoid getting sick while traveling is to only eat fruit that you peel yourself, since plants can filter out bacteria and prevent it from traveling throughout their tissues. Well, why not apply this principle to filtering water directly? A team of scientists have done just that, testi... Read More
The fungal pathogen Candida albicans causes yeast infections, diaper rashes and oral thrush, and is the most common fungal pathogen to infect humans. Researchers have identified a protein that the fungus uses to defend itself against the human body. Another concern with the fungus is that it can... Read More
Bravo Randy Schekman!
I strongly support your comments on the tyranny of "impact factors" and I will be pleased to join in efforts to prevent the misuse of these ratings.
Impact Factors have become a symbol of terror for scientists in all disciplines and their use in promotion and other ... Read More
Shellfish such as mussels and barnacles secrete very sticky proteins that help them cling to rocks or ship hulls, even underwater. Inspired by these natural adhesives, a team of MIT engineers has designed new materials that could be used to repair ships or help heal wounds and surgical incisions... Read More
One genome at a time can be exciting, but two even more so. I’m not entirely sure why this is, although it may explain our fascination with sex. And what if more than two entities were involved? What if the intimacy were not just between two individual organisms, but between a greater number of ... Read More
The TWiV team discusses transmission of Ebola virus, and inhibition of Borna disease virus replication by viral DNA in the ground squirrel genome.
We continue our semi-annual ritual and post this quick tour of our featured blog posts published since June 2013.
Microbial ‘Starstuff’. Associate blogger Gemma Reguera tells us how the remnants of a dying star become transmuted into microbial stuff, including cellular structures... Read More
Could Ebola go airborne? That’s the fear set off last week by a New York Times op-ed entitled “What We’re Afraid to Say about Ebola” from Michael Osterholm, director of the Center for Infectious Disease Research and Policy at the University of Minnesota. Although clinicians readily agree that th... Read More
Nearly 40 years ago, a young Belgian scientist travelled to a remote part of the Congolese rainforest - his task was to help find out why so many people were dying from an unknown and terrifying disease.
In September 1976, a package containing a shiny, blue thermos flask arrived at the Instit... Read More
How often have you heard of two or more bacterial species coexisting within the same cell of a host? It’s known to happen with some frequency in some amebas, insects and other invertebrates (including the strange case of the mealybug bacteria, which have an endosymbiotic bacterium that carries a...

Cells, biological circuits, and individual biomolecules organize themselves and interact with the environment. Use of these capabilities in flexible and economically efficient biotechnological production systems is in the focus of the "Molecular Interaction Engineering" (MIE) project. It is the ... Read More
If you happened to be reading state health departments’ outbreak announcements this past weekend, you might have seen something interesting.
(You don’t do this? Hmm.)
Three states — Rhode Island, North Carolina and Tennessee — all said that they have identified residents who have been diag... Read More
A group of researchers at the Max F. Perutz Laboratories has created one of the three world's largest gene libraries for the Candida glabrata yeast, which is harmful to humans. Molecular analysis of the Candida glabrata fungus mutations led to the discovery of 28 new genes that are partly respon... Read More
