Biologists spy close-up view of poliovirus linked to host cell receptor
Researchers from Purdue and Stony Brook universities have determined the precise atomic-scale structure of the poliovirus attached to key receptor molecules in human host cells and also have taken a vital snapshot of processes leading to infection.

Researchers study virus with unusual properties
A team of researchers from Penn State University and the University of Chicago has uncovered clues that may explain how and why a particular virus, called N4, injects an unusual substance -- an RNA polymerase protein -- into an E. coli bacterial cell.

Variations in gut microbial communities linked to obesity
Trillions of microbes make their home in the gut, where they help to break down and extract energy and nutrients from the food we eat. Yet, scientists have understood little about how this distinctive mix of microbes varies from one individual to the next.

Chemist finds gray mold's killer gene
Gray mold is a gardener's nightmare. The fungus, also known by its scientific name Botrytis cinerea, is a scourge to more than 200 agricultural and ornamental plant species, including staples such as tomatoes, strawberries, snap and lima beans, cabbage, lettuce and endive, peas, peppers, and potatoes.

Social amoeba seek kin association
Starving "social amoebae" called Dictyostelium discoideum seek the support of "kin" when they form multi-cellular organisms made up of dead stalks and living spores, said researchers from Baylor College of Medicine and Rice University in Houston in a report that appears online today in the open-access journal Public Library of Science Biology.

Escherichia coli bacteria transferring between humans and mountain gorillas
A new study finds that mountain gorillas are at increased risk of acquiring gastrointestinal microbes, such as Escherichia Coli, from humans. The study, published in Conservation Biology, examines the exchange of digestive system bacteria between humans, mountain gorillas and domestic animals with overlapping habitats.

Scientists present 'moving' theory behind bacterial decision-making
Biochemists at North Carolina State University have answered a fundamental question of how important bacterial proteins make life-and-death decisions that allow them to function, a finding that could provide a new target for drugs to disrupt bacterial decision-making processes and related diseases.

Bacteria that cause stomach ulcers and cancer could also be giving us bad breath, according to research published in the December issue of the Journal of Medical Microbiology. For the first time, scientists have found Helicobacter pylori living in the mouths of people who are not showing signs of stomach disease.

Bacteria that can cause serious heart disease in humans are being spread by rat fleas, sparking concern that the infections could become a bigger problem in humans. Research published in the December issue of the Journal of Medical Microbiology suggests that brown rats, the biggest and most common rats in Europe, may now be carrying the bacteria.

Imagine yourself swimming in a pool: It's the movement of your arms and legs, not the viscosity of the water, that mostly dictates the speed and direction that you swim.

Researchers get first 3-D glimpse of bacterial cell-wall architecture
The bacterial cell wall that is the target of potent antibiotics such as penicillin is actually made up of a thin single layer of carbohydrate chains, linked together by peptides, which wrap around the bacterium like a belt around a person, according to research conducted by scientists at the California Institute of Technology (Caltech).

Herpes drug inhibits HIV replication, but with a price
The anti-herpes drug acyclovir can also directly slow down HIV infection by targeting the reverse transcriptase (RT) enzyme, researchers report in this week's JBC. This beneficial effect does pose a risk though, as HIV-infected cells treated with acyclovir promote the emergence of multi-drug resistant HIV variants.
