Scientists have introduced a method based on a non-classical state adapted to two measurement parameters at once. This will enable precision measurements of molecules which could reveal interactions between conventional and dark matter.

It was the most serious release of radioactive material since Fukushima 2011, but the public took little notice of it: In September 2017, a slightly radioactive cloud moved across Europe. Now, a study has been published, analyzing more than 1300 measurements from all over Europe and other regions of the world to find out the cause of this incident.

One of the fundamental physical constants, the 'weak axial vector coupling constant' (gA), has now been measured with very high precision for the first time. It is needed to explain nuclear fusion in the sun, to understand the formation of elements shortly after the Big Bang, or to understand important experiments in particle physics. With the help of sophisticated neutron experiments, the value of gA has now been determined with an accuracy of 0.04%.

Scientists have demonstrated a new bio-inspired material for an eco-friendly and cost-effective approach to recovering uranium from seawater. The low-cost polymer adsorbent could help push past bottlenecks in the cost and efficiency of extracting uranium resources from oceans for sustainable energy production.

Technology to measure the flow of subatomic particles known as antineutrinos from nuclear reactors could allow continuous remote monitoring designed to detect fueling changes that might indicate the diversion of nuclear materials. The monitoring could be done from outside the reactor vessel, and the technology may be sensitive enough to detect substitution of a single fuel assembly.
