Finding all asteroid threats to human populations: NASA announces asteroid grand challenge
18 Jun 2013 | 4:20 pm
NASA has announced a Grand Challenge focused on finding all asteroid threats to human populations and knowing what to do about them. The challenge is a large-scale effort that will use multi-disciplinary collaborations and a variety of partnerships with other government agencies, international partners, industry, academia, and citizen scientists. It complements NASA's recently announced mission to redirect an asteroid and send humans to study it.

Tiny batteries: 3-D printing could lead to miniaturized medical implants, compact electronics, tiny robots
18 Jun 2013 | 1:14 pm
Three-dimensional printing can now be used to print lithium-ion microbatteries the size of a grain of sand. The printed microbatteries could supply electricity to tiny devices in fields from medicine to communications, including many that have lingered on lab benches for lack of a battery small enough to fit the device, yet provide enough stored energy to power them.
