A brain implant turns “loser” mice into aggressive fightersEnlarge / Could this be the first step toward the Mouse Guard from David Petersen's amazing comic book?

Scientists have turned shy, low-ranking mice into aggressive fighters who almost always win in dominance competitions. And they did it by stimulating a part of the

A biophysical smoking gunWhile much about Alzheimer's disease remains a mystery, scientists do know that part of the disease's progression involves a normal protein called tau, aggregating to form ropelike inclusions within brain cells that eventually strangle the neurons. Yet how this protein transitions from its soluble liquid state to solid fibers has remained unknown — until now.

Aggressive UTI bacteria hijack copper, feed off itResearchers at Washington University School of Medicine in St. Louis have shown that Escherichia coli (E. coli) bacteria — those at the root of hard-to-treat urinary tract infections (UTIs) — hijack trace amounts of copper in the body and use it as a nutrient to fuel growth. The finding suggests blocking this system may starve E. coli infections, opening the door to treating UTIs using drugs tha

5% fewer vaccinations would spike measles casesA five percent drop in the number of children ages 2 to 11 inoculated against the measles, mumps, and rubella would triple the number of annual measles cases in this age group, a new study warns. The MMR vaccine is an inoculation against all three diseases. The additional measles cases would increase annual public health expenditures by at least $2.1 million, or $20,000 per case of measles. “I th

‘Virus cam’ can catch germs in the actA team of researchers has developed a microscope powerful enough to see a virus in the act of infecting a cell. The team’s new 3D “virus cam” can spy on tiny viral germs as they wriggle around in real time. In a video caught by the microscope, you can watch as a lentivirus bounces and jitters through an area a little wider that a human hair. The team used their 3D virus cam to spy on this small l

“Post-Ebola syndrome” is something else to keep you up at nightEbola virus (credit: CDC Global ) After the ghastly symptoms subside, Ebola may not be done; it may just shift to a clever stealth mode , a new study suggests. Examining archived tissue samples from infected monkeys, researchers found that Ebola can create a cryptic viral reservoir in certain immune cells and hide in corners of the body where the rest of the immune system has little reach. The st

Antibody-induced uncoating of human rhinovirus B14 [Biophysics and Computational Biology]Rhinoviruses (RVs) are the major causes of common colds in humans. They have a nonenveloped, icosahedral capsid surrounding a positive-strand RNA genome. Here we report that the antigen-binding (Fab) fragment of a neutralizing antibody (C5) can trigger genome release from RV-B14 to form emptied particles and neutralize virus infection. Using…
