Scientists are gaining an insider's look behind the notorious infectivity of Francisella tularensis. This bacterium is an equal opportunity pathogen. It causes the disease tularemia in humans, rabbits and rodents, among others.
Also called rabbit fever, the disease doesn't seem to spread from... Read More
Since Dr. Adam Levine arrived in Haiti in late October, he’s been managing a cholera treatment unit for International Medical Corps. Hurricane Matthew devastated the area on Oct. 4, creating conditions that foment the spread of the disease. The unit is still running near its 30-bed capacity.

German physicist Michael Lässig believes that soon it may be possible to make evolutionary forecasts. Scientists may not be able to predict what life will be like 100 million years from now, but they may be able to make short-term forecasts for the next few months or years. And if they’re making...

Scientists report that social media plays far more than a social role in their lives—for many, it is a major way that they communicate about science, solve problems, and even share their work. Together with open-access publishing and data sharing, social media are part of how some science is bei... Read More
While bacteria have been evolving for 3.5 billion years, mammals have evolved with bacteria for only 2.5 million years. Thus, it's not that surprising that humans appear to be losing the war on antibiotic resistance.
The issue of multidrug-resistance and the lack of antibiotics in the developme... Read More
Astrobiología y ambientes extremos: En el episodio de hoy tenemos al Dr. Salvador Mirete, Investigador del Centro de Astrobiología, del Instituto Nacional de Técnica Aeroespacial de Madrid, España. La astrobiología se discute dentro del contexto de los ambientes extremos encontrados en la Tie... Read More
Houston Methodist researchers have discovered a set of immune proteins that facilitate long-lasting immunity against malaria. In a study recently published in Immunity (online Oct. 25), researchers reported that elevated production of specific proteins regulating the immune system within 24 hour... Read More
Aravinda de Silva, PhD, professor of microbiology and immunology, and Stefan Metz, PhD, a post-doc in de Silva's lab, make up one of only two U.S. teams to be named to the European Union-funded worldwide initiative. Sponsored by the European Union's Horizon 2020 Programme, the consortium is inve... Read More
Federal scientists have launched another test in human volunteers of a Zika vaccine. This one uses a more traditional approach than an experiment that started in August.
Federal officials are eager to develop a vaccine as quickly as possible, which is why they are pursuing multiple approaches... Read More
Q. Are people who work with books and manuscripts from the 14th and 15th centuries at risk from disease-causing bacteria or viruses from that time?
A. Almost certainly not, because of how diseases spread and how long most microbes can survive on dry surfaces.

Raw milk collected from dairy farms has to travel to processing facilities before it is transformed into the delicious dairy products we consume. Because the milk from many dairy cows is collected together, any contamination issue from a single animal can lead to spoilage or contamination. How r... Read More
ust five months after federal health officials asked hospitals and physicians to be on the lookout for an often-fatal, antibiotic-resistant fungus called Candida auris, 13 cases have been reported, the Centers for Disease Control and Prevention announced Friday. It is the first time that the fun... Read More
Two studies, in the journal Cell, found a mutation increased the virus' ability to infect human cells fourfold.
Scientists have argued the mutation may have been "pivotal" in the outbreak becoming the largest in recorded history.
There were 28,616 Ebola cases in Guinea, Liberia and Sierra ... Read More
Recent advances in imaging technology have provided unprecedented views of biological events as they unfold in living organisms. Researchers routinely create movies of processes such as cells dividing and differentiating into the neurons, muscle, and skin in a Petri dish or in tiny embryos, such... Read More
Parasitic flatworms known as schistosomes require a gene called cpb1 in order to survive in mice, according to a new study published in PLOS Pathogens. The study also shows that schistosome stem cells grow in response to injury.
Schistosomes afflict more than 200 million people worldwide and ... Read More
Researchers at Oregon State University have identified for the first time another bacterium that can cause symptoms similar to "salmon poisoning" in dogs - and may complicate the efforts of Pacific Northwest pet owners to keep their dogs protected and healthy.
The Pacific Northwest, from nort... Read More
