The road to finding a cure for HIV-1 is not without obstacles. However, thanks to cutting-edge research by Douglas Nixon, M.D., Ph.D., and colleagues, performed at the George Washington University (GW), Oregon Health & Science University, the University of Rochester, and UC San Francisco, the sc...

Vibrio cholerae was isolated in the capital city Kathmandu , where as it causes cholerae endemic in certain remote parts in the country every year . Vibrio cholerae O1 ogawa serotype was isolated and identified after growth in TCBS agar and subcultured on HIA plate and performed oxidase test (+... Read More
Soil deep in a crater dating to some 3.7 billion years ago contains evidence that Mars was once much warmer and wetter, says University of Oregon geologist Gregory Retallack, based on images and data captured by the rover Curiosity.
NASA rovers have shown Martian landscapes littered with loos... Read More
Methyl Red/Vogoes-Proskauer (MR-VP)
One medium used for two separate but related tests, identifying butanediol (VP) or acidic fermentation products (MR) as part of the IMViC test used in the identification of Enterobacteriaceae.
•Methyl Red (MR): detects the ability of an organism to produc... Read More
Some heavy metals share a long history with microbes. Many of the metabolic processes that sustain life are believed to have originated from spontaneous reactions involving metals present in the early Earth. Our microbial ancestors figured out quickly how to use those metal catalysts to generate... Read More
Imagine you were forced to live in perpetually subzero temperatures, with no oxygen, no light, and way more salt than your system could handle. How would you manage? One way might be to get extremely small. At least, that seems to be what’s happening in a frozen Antarctic lake that’s cut off fro... Read More
Material from deadly pathogens triggers alerts directly, and could speed detection.

In September 1976, a package containing a shiny, blue thermos flask arrived at the Instit... Read More
Urea is a small molecule formed as proteins are broken down. It’s excreted in urine, but isn’t particularly toxic at low levels so it’s found in cells throughout the body. The molecular structure of urea is below, and as it contains nitrogen (N) several pathogens have adapted to use it as a nitr... Read More
