For the first time ever, experimental physicists have been able to influence the magnetic moment of materials in sync with their electronic properties. The coupled optical and magnetic excitation within one femtosecond corresponds to an acceleration by a factor of 200 and is the fastest magnetic phenomenon that has ever been observed.
In new research from Berkeley Lab and our collaborators, scientists discovered how a protein produced by bullfrogs inhibits the deadly neurotoxin involved in red tide events, glimpsed how atoms move in four dimensions, and identified a bacterial gene that could be engineered into biofuel-producing microbes to greatly boost process efficiency.
University of Tokyo graduate student Yuuki Wada with colleagues from Japan discover a connection between lightning strikes and two kinds of gamma-ray phenomena in thunderclouds. The research suggests that in certain conditions, weak gamma-ray glows from thunderclouds may precede lightning bolts and their accompanying gamma-ray flashes.
Analysis of energy loss in low-aspect ratio tokamaks opens a new chapter in the development of predictions of transport in such facilities.
An international research team led by the University of Liverpool has made a discovery that will help with the search for electric dipole moments (EDM) in atoms, and could contribute to new theories of particle physics such as supersymmetry.
North Korea detonated a nuclear device in 2017 equivalent to about 250 kilotons of TNT, a new study in AGU's Journal of Geophysical Research: Solid Earth estimates. The 2017 test was an order of magnitude larger than the previous five underground tests at North Korea's Punggye-ri test site, according to the new study, which took into account the geology of the test site to estimate the size of the explosions from distant seismic recordings of the blasts.
In a study that combines groundbreaking experimental work and theoretical calculations, researchers at the US Department of Energy's (DOE) Argonne National Laboratory, in collaboration with scientists in Germany and Poland, have determined the nuclear geometry of two isotopes of boron. The result could help open a path to precise calculations of the structure of other nuclei that scientists could experimentally validate.
Scientists from the University of British Columbia, the Massachusetts Institute of Technology, the University of Maryland, the Lawrence Berkeley National Laboratory, and Google are conducting a multi-year investigation into cold fusion, a type of benign nuclear reaction hypothesized to occur in benchtop apparatus at room temperature.
Release describes application of machine learning form of artificial intelligence to predict the behavior of fusion plasma.
Researchers provide the first direct evidence for a rare kind of atomic nucleus. The special nickel nucleus (78Ni) is an isotope of typical nickel (58Ni), meaning they share the same number of protons but a different number of neutrons. Usually more neutrons make isotopes less stable, but this isotope is special. 78Ni is more tough or rigid than other nickel isotopes with similar numbers of neutrons -- it takes more energy to excite 78Ni into a different state.
