Microbiologists find defense molecule that senses respiratory viruses
Research points toward potential immune therapies for individuals at high risk for RSV and flu, two common respiratory viruses.

Some brain tumors may be mediated by tiny filament on cells
UCSF scientists have discovered that a tiny filament extending from cells, until recently regarded as a remnant of evolution, may play a role in the most common malignant brain tumor in children.

NASA sees some strong thunderstorms in Bill's center as he drenches eastern Canada
Bill is still holding onto hurricane status near Nova Scotia, and will be bringing a lot of rain and heavy surf to Nova Scotia, Prince Edward Island and Newfoundland.

U-M researchers discover therapeutic target that could help patients with pulmonary fibrosis
Researchers at the University of Michigan have discovered that targeting of a novel gene utilizing genetic and pharmacologic strategies was successful in treating pulmonary fibrosis in mice and will be developed for future testing in humans.

Fragile period of childhood brain development could underlie epilepsy
A form of partial epilepsy associated with auditory and other sensory hallucinations has been linked to the disruption of brain development during early childhood, according to a study led by researchers at Beth Israel Deaconess Medical Center.
