Out of an hours-long explosion, a stand-in for the first stars

In this artist's rendering of GRB 130925A, a sheath of hot, X-ray-emitting gas (red) surrounds a particle jet (white) blasting through the star's surface at nearly the speed of light. The source may have been a metal-poor blue supergiant.Astronomers analyzing a long-lasting blast of high-energy light observed in 2013 report finding features strikingly similar to those expected from an explosion from the universe's earliest stars. If this interpretation...

Scientist finds link between antibiotics, bacterial biofilms and chronic infections

The bacteria called non-typeable <i>Haemophilus influenzae</i> are a common cause of infection in the upper respiratory tract. By attaching to surfaces in the body the bacteria form a biofilm. Wu et al. have reported that when the bacteria encounter non-lethal amounts of specific antibiotics they are stimulated to form a bioiflm, a structure that causes chronic infection and which can be highly resistant to antibiotics.Researchers from the University of Southern California and the Oak Crest Institute of Science have discovered the link between antibiotics and bacterial biofilm formation leading to chronic lung, sinus and...
