Nuclear batteries can last decades, but their power density is currently too low to be very practical. Now, Russian researchers have developed a new nuclear battery design based on nickel-63, which has a higher specific energy than regular, commercially-available batteries.

Thorium reactors have long been proposed as a cleaner, safer alternative to nuclear energy. Now Russian scientists propose a new thorium reactor design that can burn weapons-grade plutonium, producing power and thermal energy while disposing of nuclear waste at the same time.

Space is a very hostile place for electronics, so BAE Systems is rolling out its new RAD5545 single-board computer designed to survive the hard radiation in space while providing "exponential improvements" over the company's previous RAD750 SBC in terms of size, speed, and power-efficiency.

Much of our understanding of ancient history comes from radioisotope dating, where scientists count isotopes in a rock sample to determine its age. But a flaw in this technique may be skewing the results to seem much older than they really are, according to new research out of NC State University.

After the Fukushima nuclear plant accident occurred, millions of gallons of radioactive water was left over. Scientists from Texas and Russia, however, may know what to do with it. They've developed a type of carbon that can reportedly filter radionuclides from water.

Among the many problems plaguing the cleanup at Fukushima is the threat of radioactive water spilling from the site. The Japanese government is now ramping up its efforts to contain this problem, by flicking the switch on an underground ice wall that will enclose the failed nuclear facility.

A new study from Imperial College London suggests that fossil fuel carbon emissions may be so diluting radioactive carbon isotopes in the atmosphere that within decades it will difficult to differentiate between modern artifacts and those over a thousand years old.

A drug used to counter the negative effects of chemotherapy has won FDA approval for use in treating the effects of radiation exposure to following a nuclear disaster. The drug, Neupogen, has been shown to work by shielding the body's white blood cells to heighten a patient's chances of survival.
