Washington, DC – September 22, 2015 - Scientists have discovered a new virus that can be transmitted through the blood supply. Currently, it is unclear whether the virus is harmful or not, but it is related to hepatitis C virus (HCV) and human pegivirus (HPgV), the latter of which was formerly k... Read More
A suspected case of sexual transmission of Ebola virus disease (EVD) in Liberia was confirmed using genomic analysis, thanks to in-country laboratory capabilities established by U.S. Army scientists in collaboration with the Liberian Institute for Biomedical Research (LIBR). Read More
More than a cause of a simple infection, viruses are often involved in the development of serious diseases. Such is the case with liver cancer, which often develops in an organ that has been weakened by hepatitis B or C virus. Researchers at Inserm, the Paris Public Hospitals (AP-HP), Paris Desc...

A new type of cancer therapy based on seemingly unrelated elements of malaria and cancer is showing promise for development. Kairos Therapeutics, a Vancouver-based biotech company spun-out of The Centre for Drug Research and Development (CDRD), has partnered with VAR2 Pharmaceuticals to advance ... Read More
The immune system is our biological defense shield. Antibodies protect the organism against invading pathogens such as viruses or bacteria. In the case of certain autoimmune diseases, however, this defense behavior is misdirected: The antibodies don't just target foreign substances; they also at... Read More
The TWiPanosomes solve the case of the Young Man from Anchorage, and discuss how cestode parasites increase the resistance of brine shrimp to arsenic toxicity.
Compared with routine medical care, probiotics administered to critically ill patients in intensive care units showed no benefit in preventing the colonization of drug-resistant microbes in the intestinal tract, according to new research at Washington University School of Medicine in St. Louis.

Washington, DC —October 6, 2015— HIV particles are effectively trapped by the cervicovaginal mucus from women who harbor a particular vaginal bacteria species, Lactobacillus crispatus. The findings, published this week in mBio, an online open-access journal of the American Society for Microbiolo... Read More
A deadly parasite that causes Chagas disease is widespread in a common Texas insect, according to a new study by University of Texas at El Paso (UTEP) researchers. The finding suggests that the risk of Texans contracting the disease may be higher than previously thought. Read More
Host: Jeff Fox with special guest, Warren C. Ruder.
Warren C. Ruder of Virginia Polytechnic Institute and State University (Virginia Tech) in Blacksburg, Virginia talks with Jeff Fox about efforts to develop an electronic model system that incorporates a robot for a host and two sligh... Read More
A team led by researchers at UC Santa Cruz has developed chip-based technology for reliable detection of Ebola virus and other viral pathogens. The system uses direct optical detection of viral molecules and can be integrated into a simple, portable instrument for use in field situations where r... Read More
Trillions of bacteria populate the human gut - which makes them more common than any other cells in our body. The composition of this bacterial population is very variable and influenced by our diet. Diseases, but also antibiotic treatments can induce significant shifts in this equilibrium. If e... Read More
The TWiM team explores microbes in snowblower vents on the ocean floor, and cleavage of antibody molecules by a Mycoplasma protease.

Previously, biologists at Emory University and the University of Michigan discovered that butterflies use plant toxins as a drug to cure their offspring of parasitic infections. Now they've dug a little deeper and found that the fungi associated with the roots of milkweed plants change both the ... Read More
