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
The science behind the transformation from plants to milk to cheese is amazing. In fact, cheese has much in common with wine and beer: They result from fermentation by microorganisms; they are “value-added” products where processing greatly increases the value; and they reflect local climate and...

One of the world's oldest known disinfectants – and favorite salad dressings – may prove even stronger than previously thought.
An international research team has found that vinegar – or, more specifically, the active ingredient in vinegar – can kill mycobacteria, including a highly drug-resi... Read More
OpenBiome, a company based in Cambridge, Mass., has opened a facility that collects stool samples from healthy, pre-screened individuals. It then processes those "donations" and readies them for shipment to hospitals, where they are put into the colons of people with the deadly gut infection Cl... Read More
Virulence, the capacity to cause disease, varies markedly among viruses. Some viruses cause lethal disease while others do not. For example, nearly all humans infected with rabies virus develop a disease of the central nervous system which ultimately leads to death. In contrast, most humans are ... Read More
Uno de los patógenos más importantes en América Latina y seguramente el mundo entero, el rotavirus, es discutido en este episodio de La Radio El Mundo de los Microbios. La Prof. Delfina Urbina, con una larga trayectoria en diferentes áreas de la Microbiología nos visita hoy. Fué Profesora Tit... Read More
Teaming beneath Sweden's thawing permafrost is a previously undiscovered microbe known as methanongen (Candidatus Methanoflorens Stordalenmirensis). As its name suggests, the microbe does one thing really well: release methane into the atmosphere, presenting a feedback loop of gas production tha... Read More
The bacterium Staphylococcus Aureus (S. aureus) is a common source of infections that occur after surgeries involving prosthetic joints and artificial heart valves. The grape-shaped microorganism adheres to medical equipment, and if it gets inside the body, it can cause a serious and even life-t... Read More
Public health officials issued a warning Thursday that thousands of Bay Area residents were potentially exposed to measles last week when a UC Berkeley student with the virus attended classes in Berkeley and rode on BART.
The student, a Contra Costa County resident whose name was not released... Read More
Washington University in St Louis chemist Timothy Wencewicz says we’ll stay ahead of antibiotic resistance only if we find drugs with new scaffolds, or core chemical structures. One promising candidate, an antibiotic made by a bacterium than infects plants, caught his attention because it contai... Read More
To my great delight, I just discovered your podcasts twiv, twim and twip.
The first twip I heard, about Strongyloides stercoralis, although informative and interesting, seemed to have several inaccuracies. I w... Read More
Communication is vital to any successful relationship. Researchers from the Institute of Food Research and the University of East Anglia have discovered how the beneficial bacteria in our guts communicate with our own cells.
This is a key step in understanding how our bodies maintain a close ... Read More
For reasons that still aren't well understood, bacteria proliferate in microgravity. Creating a potential recipe for disaster for humans stationed in space for long periods, bacteria's love of low-g also raises an intriguing question: Why are they so comfortable there?

In a first-of-its-kind study for Lyme disease, researchers have used live, disease-free ticks to see if Lyme disease bacteria can be detected in people who continue to experience symptoms such as fatigue or arthritis after completing antibiotic therapy. The technique, called xenodiagnosis, attem... Read More
After 26 years of workdays spent watching bacteria multiply, Richard Lenski has learned a thing or two.
He's learned that naturalist Charles Darwin was wrong about some things. For one, evolution doesn't always occur in steps so slow and steady that changes can't be observed.
Lenski also lea... 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...

While genetics likely play a role in some instances of colorectal cancer, a new study in mice suggests gut bacteria could also influence development of intestinal tumors. Researchers from the Icahn School of Medicine at Mount Sinai found that giving antibiotics to mice to disrupt their microbial... Read More
Scientists have deciphered the 3-D structure of a protein that confers antibiotic resistance from one of the most worrisome disease agents: a strain of bacteria called methicillin-resistant Staphylococcus aureus (MRSA), which can cause skin and other infections. The team's findings may be an imp... Read More
