In a paper to be published tomorrow in the journal Nature, researchers announce that they have observed the radioactive decay of xenon-124, which has a half-life of 1.8 X 1022 years.
The world's most advanced particle accelerator for investigating the quark structure of the atom's nucleus has just charmed physicists with a new capability. The production of charm quarks in J/ψ (J/psi) particles by CEBAF at the Department of Energy's Thomas Jefferson National Accelerator Facility confirms that the facility has expanded the realm of precision nuclear physics research with electron beams to higher energies.
PPPL physicists have discovered valuable information about how plasma flows at the edge inside doughnut-shaped fusion devices. The findings mark an encouraging sign for the development of machines to produce fusion energy for generating electricity without creating long-term hazardous waste.
Article describes analytical confirmation that transient CHI, a novel device for starting up fusion plasmas, can achieve startup in future compact fusion facilities.
A UBC medical student has determined that a new surgical guideline is making a difference for breast cancer patients. Alex Monaghan, a second-year Southern Medical Program (SMP) student at UBC Okanagan, recently completed a study using patient data from BC Cancer-Kelowna. His research compared re-operation rates for breast cancer patients before and after a new surgical guideline was introduced five years ago.
This tip sheet highlights interesting presentations from the upcoming 2019 APS April Meeting in Denver -- a major international meeting that features talks and presentations about discoveries in astrophysics, particle physics, energy research and many other areas of modern physics. The meeting runs from Saturday, April 13 through Tuesday, April 16 at the Sheraton Denver Downtown Hotel, located at 1550 Court Place in downtown Denver.
Researchers from MIT and elsewhere review how a 'boiling crisis' can occur in environments such as nuclear power plants. The findings may lead to better designs of heat-transfer surfaces and might allow plants to generate more power with the same amount of fuel.
Radioactive iodine has been used for treatment of thyroid cancer. However, some thyroid tumors become resistant to iodine treatment. An Osaka University research team used a large accelerator to produce sodium astatide for injection, which emits highly therapeutic alpha rays that can be used in cancer treatment. This systemic alpha-ray exposure may enable breakthrough outpatient treatment of cancerous lesions throughout the body without involving external radiation therapy.
Researchers at Washington University in St. Louis have discovered and characterized a new form of oxygen dubbed 'featherweight oxygen' -- the lightest-ever version of the familiar chemical element oxygen, with only three neutrons to its eight protons.
To accelerate the process of identifying novel uranium oxide phases, an ORNL team studied 4,600 different potential crystal structures of uranium oxide compositions on Metis, a CADES high-performance computing cluster. An improved understanding of uranium oxides, which fuel the vast majority of the U.S. nuclear power fleet, could lead to the development of improved fuels or waste storage materials.
