The end of NASA's plutonium shortage may be in sight. On Monday March 18th, NASA's planetary science division head Jim Green announced that production of Plutonium-238 (Pu-238) by the United States Department of Energy (DOE) ...

Timing plant evolution with a fast-ticking epigenetic clock

Recent discoveries in the field of epigenetics, the study of inheritance of traits that occur without changing the DNA sequence, have shown that chronological age in mammals correlates with epigenetic changes that accumulate ...

Wearable electronics move beyond rigid wristbands

It's not every day that there's a news story about socks. But in November, a pair won the Best New Wearable Technology Device Award at a Silicon Valley conference. The smart socks, which track foot landings and cadence, are ...

More efficient optical quantum gates

Future quantum computers are expected not only to solve particularly tricky computing tasks, but also to be connected to a network for the secure exchange of data. In principle, quantum gates could be used for these purposes. ...
