The storm clouds in Earth's atmosphere are filled with microbial life, according to a new study.
The research, published today (Jan. 23) in the journal PLoS One, revealed that hailstones drawn from storm clouds harbor several species of bacteria that tend to reside on plants, as well as thous... Read More
In early 2012 influenza virus researchers around the world decided to stop working on highly pathogenic avian influenza H5N1 virus. This decision came after work from the Fouchier and Kawaoka laboratories revealed the isolation of influenza H5N1 strains that can be passed among ferrets by aeroso... Read More
A toxin-antitoxin system is a set of two or more closely linked genes that together encode both a protein 'poison' and a corresponding 'antidote'. There are 3 types of these systems: Type I toxin-antitoxin systems rely on the base-pairing of complementary antitoxin RNA with the toxin's mRNA, Ty... Read More

Euplotes belongs to the class Nassophorea in the phylum Ciliophora; the ciliates, of which there are approximately 8,000 species, are generally considered to be the most evolved and complex of the p... Read More
Children with eczema have a more diverse set of bacteria in their guts than non affected children, finds a new study in BioMed Central's open access journal BMC Microbiology. The types of bacteria present were also more typical of adult gut microbes than for toddlers without eczema.
Eczema is... Read More
Troublesome strains of Staphylococcus aureus are often troublesome because they carry genes for superantigens and multiple antibiotic resistance. But don’t blame the bacteria. These genes are hitchhikers that arrived by horizontal gene transfer, embedded within mobile pathogenicity islands known... Read More
A team of researchers based at Johns Hopkins has decoded a system that makes certain types of immune cells impervious to HIV infection. The system's two vital components are high levels of a molecule that becomes embedded in viral DNA like a code written in invisible ink, and an enzyme that, whe... Read More
Living cells are surrounded by a membrane that tightly regulates what gets in and out of the cell. This barrier is necessary for cells to control their internal environment, but it makes it more difficult for scientists to deliver large molecules such as nanoparticles for imaging, or proteins th...

SketchyMicro is a unique and effective way to learn high-yield medical microbiology for the USMLE Step 1.
Dissatisfied with the current medical microbiology board review resources, SketchyMicro decided to take things into their own hands. Their review course takes the plethora of microorganis... Read More
While working out the structure of a cell-killing protein produced by some strains of the bacterium Enterococcus faecalis, researchers stumbled on a bit of unusual biochemistry. They found that a single enzyme helps form distinctly different, three-dimensional ring structures in the protein, one... Read More
Early life exposure to normal bacteria of the GI tract (gut microbes) protects against autoimmune disease in mice, according to research published on-line in the journal Science. The study may also have uncovered reasons why females are at greater risk of autoimmune diseases such as multiple scl... Read More

It’s not hard to see that men are more likely to engage in risky behaviors than women, or that crime rates are many times higher among men, but this tendency to break the rules also extends to male scientists, according to a study to be published on January 22 in mBio®, the online open-access jo...

Measles virions have two envelope glycoproteins, a receptor binding hemagluttinin (H) and a fusion protein (F). When H binds to its cellular receptor, it is thought that the F protein undergoes conformational changes that assist in virus-cell fusion as well as cell-to-cell fusion. The ladder a... Read More
Poliovirus recently made the cover of Time magazine. Prompted by a reader question, I searched the Time archive to find out if there have been other virology-themed covers. I found fifteen in all, depicting poliovirus (3), herpesvirus (1), HIV/AIDS (4), influenza (5), and SARS coronavirus (2) (I... Read More
The mosquito that spreads the dengue virus is a homebody that infects visiting friends and relatives.
The Aedes aegypti mosquitoes that spread dengue fever tap into the domestic networks of humans, along with their bloodstreams, finds a study recently published in the Proceedings of the Natio... Read More
Viruses closely related to the new coronavirus that emerged last year in the Middle East have been discovered in specimens from a number of species of bats found widely throughout Europe and beyond, a new study shows.
The work suggests bats common to Europe, Russia, parts of Asia and Africa a... Read More
No one wants a hacking cough for days or weeks on end. But research shows that it generally takes about 18 days to get over a standard cough-based illness. Most of us grow impatient after a week or so and head to the doctor to get a prescription. The problem with that recourse, however, is that ... Read More
It’s always fascinating to me to see how seriously other parts of the world take the issue of antibiotic use in agriculture, given the long struggle in the United States to get the Food and Drug Administration to act and to get legislation through Congress. The European Parliament has voted down... Read More
