The changing shape of an atomic nucleus

The nucleus of an atom can have different shapes that co-exist. European scientists investigated nuclear shape change with advanced experimental techniques.

Scientists help avert a nuclear medicine meltdown

University of British Columbia scientists have shown that small cyclotrons – particle accelerators the size of an SUV – can replace hulking nuclear power plants as the country's main source of medical isotopes, the radioactive ...

Cosmic rays reveal event in Earth's magnetic field history

41 000 years ago, the Earth's magnetic field faded and practically disappeared, leaving our planet unprotected from the bombardment of cosmic rays. Evidence for this event has been found in ocean sediment cores by a team ...

No Fukushima radiation found in coastal areas

It was raining when Eric Norman, Berkeley Lab physicist and University of California (UC) Berkeley professor of Nuclear Engineering, heard about the nuclear-reactor meltdown in Fukushima, Japan. "I immediately thought of ...

Researchers recalculate age of Solar System

(PhysOrg.com) -- Lead-lead (Pb-Pb) dating is among the most widely used radiometric dating techniques to determine the age of really old things, such as the age of the Earth or the Solar System. However, recent advances in ...
