How nannoplankton hung on by a shoestring
PENN STATE (US)—An asteroid strike may not only account for the demise of ocean and land life 65 million years ago, but the fireball’s path—and resulting dust, darkness, and toxic metal contamination—may explain the geographic unevenness of extinctions and recovery. (more…)

‘Liquid’ metals could pave way for nano-scale chips
YALE (US)—A novel type of metal that is stronger and more durable than silicon or steel could prove to be the ideal material for manufacturing nano-devices, like computer chips and biomedical sensors. “Amorphous metals” known as bulk metallic glasses (BMGs) seem solid but are more like a very slow-flowing liquid that has no structure beyond the atomic level—making them ideal for molding fine details.
