UrduFor the first time, nuclear physicists made precision measurements of the short-lived radioactive molecule, radium monofluoride (RaF). The researchers combined ion-trapping and specialized laser systems to measure the fine details of the quantum structure of RaF. This allowed them to study the rotational energy levels of RaF and determine its laser-cooling scheme.

Pioneering MRI imaging method captures brain glucose metabolism without the need for administration of radioactive substances
A research team has developed a completely new magnetic resonance imaging (MRI) approach. Using a harmless glucose solution, the procedure generates reliable results and – in principle – can be used with all common MRI scanners.
New production method promises to end medical radioisotope shortages
A commonly used radioisotope, technetium-99m, used in medical diagnoses regularly suffers from shortages due to being produced at aging nuclear reactors that often shut down for repairs.
New paper addresses mix of contaminants in Fukushima wastewater, highlights risks of dumping in ocean
Ten years after the Tohoku-oki earthquake and tsunami devastated Japan’s Fukushima Dai-ichi Nuclear Power Plant, radiation levels have fallen in all but the waters closest to the plant. But a new hazard exists and is growing every day in the number of storage tanks on land surrounding the power plant that hold contaminated wastewater.
How Old are Whale Sharks? Nuclear Bomb Legacy Reveals Their Age
Nuclear bomb tests during the Cold War in the 1950s and 1960s have helped scientists accurately estimate the age of whale sharks, the biggest fish in the seas, according to a Rutgers-led study. It’s the first time the age of this majestic species has been verified. One whale shark was an estimated 50 years old when it died, making it the oldest known of its kind. Another shark was an estimated 35 years old.
Radioactive tadpoles reveal contamination clues
Tadpoles can be used to measure the amount of radiocesium, a radioactive material, in aquatic environments, according to new research from University of Georgia scientists. Whether from nuclear accidents, global fallout from weapons testing, or production of nuclear energy, tadpoles…
