Phytoplankton may be microscopic, but that doesn’t mean we can’t see them. Just look up: These little critters are brightening up cloudy days around the world. Read More
Scientists are one step closer to understanding how a normally harmless fungus changes to become a deadly infectious agent. Read More
Dear Dr. Schaechter,
First off, I want to thank you for the effort you and your colleagues have invested in Small Things Considered and the podcast TWIM. Back when I had a longer commute to work, I listened more religiously than now, wh... Read More
New Haven, Conn. -- Nearly one in four patients with chronic hepatitis C (HCV) are denied initial approval for a drug therapy that treats the most common strain of the infection, according to a Yale School of Medicine study. Read More
Parasitic wasps inject their eggs into lepidopteran hosts, where they carry out their developmental stages. Along with the eggs, the wasps also deliver viruses carrying genes encoding proteins which inhibit caterpillar immune defenses. Some of these genes are permanently transferred to the lepid...

Prion diseases--incurable, ultimately fatal, transmissible neurodegenerative disorders of mammals--are believed to develop undetected in the brain over several years from infectious prion protein. In a new study, National Institutes of Health (NIH) scientists report they can detect infectious pr... Read More

Prions are fascinating, enigmatic, and might teach us not only about rare prion diseases like Creutzfeld-Jakob disease, mad cow disease, or scrapie, but also about other more common neurodgenerative diseases. Two studies published on July 2nd in PLOS Pathogens report progress with novel tools an... Read More
ANN ARBOR, Mich. -- Like a collection of ragtag villagers fighting off an invading army, the mix of bacteria that live in our guts may band together to keep dangerous infections from taking hold, new research suggests. Read More
Although we now understand that viruses are the most abundant organisms on Earth, there are gaps in our knowledge about their distribution in different environments. Results of a new study reveal the diversity and distribution of viruses in Arctic fresh waters. Read More
Researchers led by the UCLA Fielding School of Public Health examined HIV testing trends among adults ages 50 through 64 both before and after 2006, when the Centers for Disease Control and Prevention (CDC) recommended that most doctors automatically screen all patients for HIV regardless of whe...

Shock! Horror! Some treasured molecular paleoenvironmental tools of organic biogeochemists—namely the alkenones, an esoteric group of long-chained compounds made by aquatic microalgae—are being put forward by O’Neil et al.1 as candidates for conversion to jet fuel on an industrial scale! (See... Read More
For thousands of years, people have used yeast to ferment wine, brew beer and leaven bread. Now researchers at Stanford have genetically engineered yeast to make painkilling medicines, a breakthrough that heralds a faster and potentially less expensive way to produce many different types of pla...

The discovery of bi-allelic mutations in RORC in patients with candidiasis and mycobacteriosis revealed the pivotal role of RORC in mucocutaneous immunity to Candida and in systemic immunity to Mycobacterium in humans. Read More
This blog post describes a "video meeting" between Seth Bordenstein and my freshman writing class in the Fall of 2014. My freshman class revolved around ideas in symbioses and parasitism, so Seth's ideas regarding holobionts and the hologenome were particularly apt. Furthermore, last week Seth... Read More
An Ebolavirus vaccine has shown promising results in a clinical trial in Guinea. This vaccine has been in development since 2004 and was made possible by advances in basic virology of the past 40 years. Read More
Visitors to two popular parks in South London are at risk of coming into contact with ticks that can transmit Lyme disease to humans, according to new research published in Medical and Veterinary Entomology. Read More
