The Secrets of Supervolcanoes: MIcroscopic crystals of volcanic ash are revealing surprising clues about the world's most devastating eruptions

Article Abstract:

The analysis of the microscopic crystals in ash deposits from old volcanic eruptions that has made it possible for scientists to spot warning signs well before the next big supereruption occurs is reported. The inner workings of the magma chambers that fuel supervolcanoes could evolve in ways that strongly influence the style of future eruptions and no matter how much we learn, we could not prevent an eruption.

REBUILDING BROKEN HEARTS

Article Abstract:

The article examines the process of building human heart tissue to use as patches in heart attack patients, allowing physicians to repair infarcts. Discussion focuses on the use of alginate, a polysaccharide derived from algae, as a scaffold for growing living tissue.

Volcanic Sniffing: QUANTUM-CASCADE LASER MAY DETECT IMPENDING ERUPTIONS

Article Abstract:

Quantum-cascade lasers that detect shifts in carbon 12 and carbon 13 ratios can be used to predict volcanic eruptions in advance of several months. The lasers read the mid-infrared wavelengths that are emitted by the carbon isotopes. Field tests are underway.
