Missing link found between turbulence in collapsing star and hypernova, gamma-ray burst
Extremely bright supernovas, called hypernovae, have been linked to gamma-ray bursts, but theorists have struggled to explain how a collapsing massive star could produce a magnetic field a million billion times greater than that of the sun, which is necessary to blow off the outer portions of the star and accelerate charged particles to speeds needed to produce gamma rays. A new supercomputer simulation by UC Bereley and Caltech scientists shows how this happens (2015-11-30)

Factoring for cosmic radiation could help set a more accurate 'molecular clock'
Since the 1960s, scientists have theorized the number of molecular differences in DNA, RNA and proteins from related species could pinpoint the time of their genetic divergence. A new paper by Adrian Melott at the University of Kansas examines a major hiccup in the molecular clock theory. The problem is that fossil evidence doesn't always sync with molecular dating for a variety of species. (2015-11-30)

AugerPrime looks for cosmic superaccelerators

Caution: Shrinks when warm
Most materials swell when warm, and shrink when cool. But some weird materials do the opposite. Although thermal expansion, and the cracking and warping that often result, occurs everyday -- in buildings, electronics, and almost anything else exposed to wide temperature swings -- physicists have trouble explaining why solids behave that way. New research into a material that has negative thermal expansion may lead to a better understanding of why materials change volume with temperature at all. (2015-10-08)
