...r words, a class of molecule once relegated to the sidelines may be one of the principal players in regulating cellular mechanisms. "It's exciting to see how many genes are regulated by microRNAs. We now know that this type of gene control is much more widespread than previously appreciated," says Whitehead ...Newer football helmet design may reduce incidence of concussions in high school players

Athletes were assessed with ImPACT(Immediate Post-Concussion Assessment and Cognitive Testing) to monitor injury effects and recovery and assist with decisions regarding return-to-play.

Apparently, anthrax fielded a second "stealth" iron scavenger, petrobactin, to get around the human defense against the first scavenger. Petrobactin is not bound by siderocalin.
