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.
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
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
Candida albicans is a yeast species that is part of the commensal microbiota of the body. Weakened or impaired immune system can lead to yeast infections mostly produced by Candida albicans, although other species like Candida parapsilosis, Candida glabrata and Candida tropicalis among others ar...

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
This episode: Amoebas in soil gang up on and eat much larger roundworms!
(10.5 MB, 11.3 minutes)
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
A eukaryote without a mitochondrion, and using a phage enzyme to eliminate intracellular bacteria are two topics discussed by the TWiMers on this episode.

Washington, DC – September 11, 2015 - Periodontitis is a risk factor for heart disease. Now a team of researchers has shown that a periodontal pathogen causes changes in gene expression that boost inflammation and atherosclerosis in aortic smooth muscle cells. The research is published ahead of ... Read More
Los virus son considerados por la mayoría como patógenos en todo tipo de entidades biológicas. Sin embargo la gran mayoría de los virus son inocuos a sus células hospedero. Nuestro invitado de hoy, el Dr. Paolo Zanotto es investigador y profesor en la Universidad de Sao Paolo, Bra... Read More
BOC Sciences-Drug resistance has always been one of the issues that scientists work hard to find ways out for better diseases treatment, as it hinders many drugs that were developed with much effort from taking effect in the body. And till now, there is little known about the formation of antibi... Read More
Dear Vincent, I have a fun question for your panel about Mars
SAN DIEGO, CALIF.--Rhesus monkeys were completely protected from the deadly Ebola virus when treated three days after infection with a compound that blocks the virus's ability to replicate. These encouraging preclinical results suggest the compound, known as GS-5734, should be further developed ... Read More
