Editor’s Selections: An asteroid killed the dinosaurs, innate immunity and obesity, and vaccinia virus in Brazil

Editor's Selections 15 Comments
By Vincent Racaniello

Vincent RacanielloVincent Racaniello selects several notable posts each week from molecular and cellular biology and virology. He blogs at virology blog.

  • Sixty-five million years ago, life on Earth suffered one of the worst mass extinctions of all time. The hypothesis that the impact of an asteroid in the Yucatan Peninsula played a major role in the end-Cretaceous extinction has now been reaffirmed by a collaborative study involving more than 40 scientists.
  • Mice that lack toll-like receptor 5, an innate sensor of bacterial flagellin, have increased fat pad size, blood glucose, insulin, cholesterol and triglyceride levels. These indicators return to wild-type levels when the gut flora of TLR5 knockout mice are depleted by antibiotics, showing that mucosal immune surveillance is crucial for maintaining populations of bacterial symbiotes.
  • Vaccinia virus, which is used to immunize against smallpox, has gone feral. It has moved from vaccinated humans into other animals.  In Brazil, feral vaccinia virus has become a significant emerging disease in cattle, from which it jumps back again into humans.

I’ll be back next Friday with more selections.
