Study links changes in global water cycle to higher temperatures
A new study takes an important step toward reconstructing a global history of water over the past 2,000 years. Using geologic and biologic evidence preserved in natural archives — including globally distributed corals, trees, ice, cave formations and sediments — the researchers showed that the global water cycle has changed during periods of higher and lower temperatures in the recent past.
US Department of Energy Office of Science awards $115M for High Rigidity Spectrometer project at FRIB
The U.S. Department of Energy Office of Science, or DOE-SC, has awarded $115 million for the High Rigidity Spectrometer, or HRS, project at the Facility for Rare Isotope Beams, or FRIB, at Michigan State University.
Chemical fingerprints could land the biggest catch: seafood fraudsters
New technology developed by South Australian scientists is tracking the origins of seafood in a bid to combat fraudulent labelling and improve sustainability. Chemical fingerprints found in the bones and shells of marine life is key to knowing which ocean they come from.
Tooth isotopes offer window into South Australia’s early colonial history
Published in Australian Archaeology, the new research involved isotope analysis of teeth excavated from graves to determine how many people buried were born in South Australia or Britain, as part of scientific efforts by Flinders University experts deploying this technique for the first time in the state.
Researchers observe new isotope of fluorine
Researchers at Washington University in St. Louis reported the first observations of a new form of fluorine, the isotope 13F, described March 30 in the journal Physical Review Letters. They made their discovery as part of an experiment conducted at the National Superconducting Cyclotron Laboratory at Michigan State University (MSU).
Pure promethium: ORNL extracts in-demand isotope from plutonium leftovers
An ORNL team has devised a way to extract Pm-147 from the liquid runoff left after Pu-238 production. This reduces radioactive elements that must be disposed of but also, if sustainable, could establish a domestic supply of Pm-147, for which there is already demand.
New diagnostic isotope to enhance targeted alpha therapy for cancer
Researchers in the DOE Isotope Program have developed an effective radionuclide, cerium-134, as a paired analogue of actinium and thorium that can be imaged using positron emission tomography (PET).
Scientists Recruit New Atomic Heavyweights in Targeted Fight Against Cancer
Researchers from Berkeley Lab and Los Alamos National Laboratory have developed new methods for the large-scale production, purification, and use of the radioisotope cerium-134, which could serve as a PET imaging radiotracer for a highly targeted cancer treatment known as alpha-particle therapy.
Shape-Shifting Selenium; Abrupt Change Found Between Selenium-70 and Selenium-72
Nuclear scientists recently found that the nucleus of the radioactive isotope selenium-72 has a football-like shape. This is similar to the stable, nonradioactive isotopes of selenium, but different from the disk-like shape of radioactive selenium-70 nuclei. This finding helps explain how the interaction between protons and neutrons in nuclei leads to collective behavior.
Your hair knows what you eat and how much your haircut costs
University of Utah researchers find that stable isotopes in hair reveal a divergence in diet according to socioeconomic status (SES), with lower-SES areas displaying higher proportions of protein coming from cornfed animals. It’s a way, the authors write, to assess a community’s diet and their health risks.
Introducing a New Isotope: Mendelevium-244
A team of scientists working at Berkeley Lab’s 88-Inch Cyclotron has discovered a new form of the human-made element mendelevium. The newly created isotope, mendelevium-244, is the 17th and lightest form of the element, which was first discovered in 1955 by a Berkeley Lab team.
A Change in Structure for a Superheavy Magnesium Isotope
A recent measurement exploring the structure of magnesium-40 has shown a surprising change in the structure relative to expectations. This unanticipated change could be pointing to physics missing from our theories, such as the effects of weak binding between particles.
