Submission + - Screen time is good for kids? (sciencedaily.com)

Submitted by bryanandaimee
bryanandaimee writes: Recent study found that screen time actually improves cognition. From TFA: "An eight-year Finnish study found that children who spent more time on screens tended to show better cognitive processing as teenagers, challenging common assumptions about screen use. Researchers say the key may be balancing physical activity with screen activities that encourage learning, creativity, and active thinking."

Submission + - NIST Ytterbium Atomic Clocks Set Record for Stability (nist.gov)

Submitted by bryanandaimee
bryanandaimee writes: An optical lattice clock like the one discussed earlier on slashdot has broken the stability record. Comparing two OLC's using trapped atoms of Ytterbium, the stability of the clocks was measured to 2 parts per quintillion (10^18). While the previously reported OLC used strontium, these clocks, built by another group, use Ytterbium. Interestingly, while the stability of the clocks is now the best in the world, the accuracy has yet to be measured.
