A special class of tiny gold particles can easily slip through cell membranes, making them good candidates to deliver drugs directly to target cells.
A new study from MIT materials scientists reveals that these nanoparticles enter cells by taking advantage of a route normally used in vesicle-... Read More
Recently, the American Academy of Microbiology released a new report, Viruses Throughout Life & Time: Friends, Foes, Change Agents that delves into the origin of viruses, the overlooked biological and microbial ecological role of viruses, and how these live forms have contributed to evolution. T... Read More
Saudi scientists have found gene fragments of the deadly Middle East Respiratory Syndrome (MERS) virus in air from a barn housing an infected camel and say this suggests the disease may be transmitted through the air.
MERS, a serious respiratory illness caused by a virus known as a coronaviru... Read More
Beautiful metallic colonies of E. coli growing on Endo agar which is being used mostly for differentiation and isolation of Enterobacteriaceae strains.

David writes (re lice and iron):
All I remember that I know is that one time I let my cat endure a heavy flea infestation for an unconscionably long time. I redeemed myself, if at all, by the knowledge that I slept with her a lot, and so endured a share myself (b... Read More
Material from deadly pathogens triggers alerts directly, and could speed detection. Early detection is key to slowing outbreaks of Ebola, such as the one currently spreading across west Africa that is estimated to have infected almost 1000 people, according to the latest World Health Organizatio...

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
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

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
Microbes can tailor transcriptional responses to diverse environmental challenges despite having streamlined genomes and a limited number of regulators. We present data‐driven models that capture the dynamic interplay of the environment and genome‐encoded regulatory programs of two types of prok... Read More
