UK stays cautious over thorium as nuclear fuel

(Phys.org)—The claim is dramatic: An alternative nuclear fuel that could offer a safer and more abundant alternative to the uranium that powers conventional reactors. That is what supporters have to say about thorium, a ...

Study sheds new light on why batteries go bad

A comprehensive look at how tiny particles in a lithium ion battery electrode behave shows that rapid-charging the battery and using it to do high-power, rapidly draining work may not be as damaging as researchers had thought ...

Scientists hit pay dirt with new microbial research technique

Long ago, during the European Renaissance, Leonardo da Vinci wrote that we humans "know more about the movement of celestial bodies than about the soil underfoot." Five hundred years and innumerable technological and scientific ...

New solar cell is more efficient, less costly

(Phys.org) —American innovators still have some cards to play when it comes to squeezing more efficiency and lower costs out of silicon, the workhorse of solar photovoltaic (PV) cells and modules worldwide.
