Nitin Phadnis joins Nels and Vincent to explain how he identified a gene that is responsible for male inviability in hybrids from a cross between two species of fruit flies. Read More
When virologists Fouchier and Kawaoka were isolating avian influenza H5N1 viruses that could transmit among ferrets by aerosol, there was consternation from some quarters that such viruses might escape from the laboratory and cause a pandemic in humans. Part of the fear came from the fact that t... Read More
The human microbiome, the collection of trillions of microbes living in and on the human body, is not random, and scientists believe that it plays a role in many basic life processes. As science continues to explore and better understand the role of the human microbiome. A new report from the Am... Read More
For anyone interested in Antibiotic Awareness Week, a big part of the story is that patients (or their parents) demand antibacterials even for viral infections. And doctors often comply, just to get rid of them (the patients, that is). This high-resolution PDF can be printed out for waiting ro... Read More
The Polio Wall of Fame is a set of fifteen sculptured busts of 17 individuals who made important contributions to understanding and preventing poliomyelitis. The busts are mounted on an exterior wall of Founder’s Hall at the Roosevelt Warm Springs Institute for Rehabilitation in Warm Springs, Ge... Read More
Miravirsen is a drug that binds to and blocks the function of a cellular microRNA called miR-122 that is required for the replication of hepatitis C virus (HCV). Treatment of chimpanzees chronically infected with HCV with this drug leads to suppression of viral replication. The results of a phas... Read More

From the abstract:
Games are a significant and defining part of human culture, and thei... Read More
By evaluating the bacteria and fungi found in fossilized feces, microbiologists are providing evidence to help support archeologists' hypotheses regarding cultures living in the Caribbean over 1,500 years ago. Researchers discuss how the analysis of 1,500-year-old coprolites from archeologica... Read More
Viruses that are harmless to humans might help fight the deadly scourge of bacteria that can't be treated with antibiotics, researchers say.
These viruses could be used in hand santizers, and to treat exposed surfaces in hospitals, which are hotbeds of antibiotic resistance, the researchers n... Read More
Do you remember the retrovirus XMRV, initially implicated as the cause of chronic fatigue syndrome, and later shown to be a murine virus that contaminated human cells grown in mice? Another virus thought to be associated with human disease has recently been shown to be a contaminant, derived fro... Read More
Antigenic variation is a hallmark of influenza virus that allows the virus to evade host defenses. Consequently influenza vaccines need to be reformulated frequently to keep up with changing viruses. In contrast, antigenic variation is not a hallmark of poliovirus – the same poliovirus vaccines ... Read More
Sea stars are lovely marine invertebrates with a round central body connected to multiple radiating legs (photo credit). In the past year millions of sea stars in the west coast waters of North America have melted into piles of slime and ossicles. Sea star associated densovirus might be the caus... Read More
About eight percent of human DNA is viral – remnants of ancestral infections with retroviruses. These endogenous retroviral sequences do not produce infectious viruses, and most are considered to be junk DNA. But some of them provide important functions. The protein called syncytin, which is ess... Read More
A common denizen of the undergraduate microbiology laboratory, Serratia marcescens is well known for the production of a bright red pigment, prodigiosin. Prodigiosin has been investigated over many years for its possible antimicrobial, antifungal, and even antitumor effects. Still, the relevan... Read More
The TWiPyzoites solve the case of the Uncommon Parasite, and discuss the role of eosinophils in promoting the growth of Trichinella in skeletal muscle.
Hosts: Read More
Poliovirus has been found in sewage in Israel. The virus detected is not vaccine-derived poliovirus; it is wild-type 1 poliovirus, the strain that occurs naturally in the wild and which the World Health Organization is trying very hard to eradicate from the planet. Read More
Researchers have found that apoptosis, a natural process of programmed cell death, can reactivate latent herpesviruses in the dying cell. The results of their research, which could have broad clinical significance since many cancer chemotherapies cause apoptosis, was published ahead of print in ... Read More
A new study led by researchers at the University of Minnesota has found a three-way link among antibiotic use in infants, changes in the gut bacteria, and disease later in life. The imbalances in gut microbes, called dysbiosis, have been tied to infectious diseases, allergies and other autoimmun... Read More
Many people have a new awareness of the disease known as amyotrophic lateral sclerosis, or ALS, thanks to the Ice Bucket Challenge initiated by the ALS Association. Fewer might know that retroviruses have been proposed to play a role in the development of the disease. Read More
Most gut bacteria are beneficial, aiding food digestion, producing vitamins, and protecting against harmful bacteria. If left unchecked, however, harmful bacteria can excrete... Read More
