Investigating ocean currents using uranium-236 from the 1960s

Stephan Winkler, isotope researcher at the University of Vienna, has identified the bomb-pulse of uranium-236 in corals from the Caribbean Sea for the first time. 236U was distributed world-wide in the period of atmospheric ...

Researchers use new technique to date CAIs and chondrules

(Phys.org)—Researchers working out of the University of Copenhagen have published a paper in the journal Science in which they claim that a new method of dating chondrules and calcium-aluminum–rich inclusions (CAIs) is ...

Scientists refine Earth's clock

New research has revealed that some events in Earth's history happened more recently than previously thought.

Team aims to produce medical isotopes without nuclear reactor

Producing medical isotopes safely, cheaply and reliably without using a nuclear reactor or weapons-grade uranium is the aim of a research project led by the Canadian Light Source (CLS) along with the National Research Council ...

New type of nuclear fission discovered

(PhysOrg.com) -- Nuclear fission, or the splitting of a heavy nucleus, usually results in symmetrical fragments of the same mass. Physicists attribute the few known examples of fission that is asymmetric to the formation ...

Engineers develop technique to help combat nuclear proliferation

Ben-Gurion University of the Negev engineers have developed a technique to "denature" plutonium created in large nuclear reactors, making it unsuitable for use in nuclear arms. By adding Americium (Am 241), a form of the ...
