Atomic fingerprint identifies emission sources of uranium
Depending on whether uranium is released by the civil nuclear industry or as fallout from nuclear weapon tests, the ratio of the two anthropogenic, i.e. man-made, uranium isotopes 233U and 236U varies. These results were lately found by an international team at the University of Vienna and provides a promising new ''fingerprint'' for the identification of radioactive emission sources. As a consequence, it is also an excellent environmental tracer for ocean currents. (2020-03-09)

Not everything is ferromagnetic in high magnetic fields
High magnetic fields have a potential to modify the microscopic arrangement of magnetic moments because they overcome interactions existing in zero field. Usually, high fields exceeding a certain critical value force the moments to align in the same direction as the field leading to ferromagnetic arrangement. However, a recent study showed that this is not always the case. The experiments took place at the high-field magnet at HZB's neutron source BER II. (2020-02-10)

After the deal: Partnerships with Iran could reduce long-term nuclear risks
The United States and five world powers hope to soon finalize a nuclear deal with Iran to limit its nuclear activities in exchange for a relaxing of international economic and financial sanctions.

Study reveals single-step strategy for recycling used nuclear fuel
A typical nuclear reactor uses only a small fraction of its fuel rod to produce power before the energy-generating reaction naturally terminates. What is left behind is an assortment of radioactive elements, including unused fuel, that are disposed of as nuclear waste in the United States. Although certain elements recycled from waste can be used for powering newer generations of nuclear reactors, extracting leftover fuel in a way that prevents possible misuse is an ongoing challenge. (2020-05-04)
