A ribbon-cutting ceremony has been held to formally open the Argonne TRACER Center (Trace Radioisotope Analysis Center) at the U.S. Department of Energy’s (DOE) Argonne National Laboratory. The TRACER Center provides a new, permanent home for the nation’s only laser-based krypton atom-counting machine. The center employs a novel technique called Atom Trap Trace Analysis (ATTA) that captures and counts isotopes of the rare element krypton (Kr) to determine the age of ice and groundwater. One of only a few such devices in the world, it provides valuable information about the dynamics, flow rates and direction of water in aquifers, particularly those vital to arid regions. Read more.
Actinium-225 has shown promise as an actual radioactive medicine that can kill cancer cells — and only cancer cells — by delivering an intense but hyper-local blast of energy
Canada’s particle physics laboratory TRIUMF is making a push to be a future world leader in the production of a special radioactive isotope nicknamed the “rarest drug on Earth,” which can deliver devastating amounts of energy to single cancer cells, without harming nearby tissue. Read more.
Researchers at Yale University have reported a new imaging modality, known as deuterium metabolic imaging (DMI), in which sugars and other nutrients are labelled with a heavy hydrogen (2H) atom and subsequently administered to track and monitor their uptake and metabolism.
Mapping glucose metabolism is important for monitoring the development and treatment of cancer, as tumours metabolize glucose both at an elevated rate and through a different set of chemical reactions compared with healthy tissue — a phenomenon known as the Warburg effect. Read more.
Chemical analyses of skull pieces suggest some of the dead came from Wales
A new analysis of cremated human remains interred at the iconic site between around 5,000 and 4,400 years ago provides the first glimpse of who was buried there. Some were outsiders who probably spent the last decade or so of their lives in what’s now West Wales, more than 200 kilometers west of Stonehenge, researchers report. Read more.
A long-standing controversy over the date of a volcanic blast that possibly inspired the myth of Atlantis may have been resolved with the aid of ancient tree rings, a new study finds.
One of the largest volcanic eruptions in the past 4,000 years burst from the volcano Thera on what is now the Greek island of Santorini. The catastrophic eruptions spewed forth about 40 to 60 cubic kilometers of lava, devastating the ancient seafaring Minoan civilization, potentially inspiring the legend of the lost city of Atlantis.
