How algae use a 'sulfate trap' to selectively biomineralize strontium
(PhysOrg.com) -- In any kind of nuclear reactor, there is a small amount of the radioactive isotope strontium-90 that is formed as part of the regular fission process. In fact, fission products such as strontium-90 ...

Toward faster transistors: New physical phenomenon could lead to increases in computers' clock speed
In the 1980s and ’90s, competition in the computer industry was all about "clock speed" — how many megahertz, and ultimately gigahertz, a chip could boast. But clock speeds stalled out almost 10 ...
