Study in NEJM indicates dietary fatty acids may influence atherosclerosis in a segment of the population genetically at risk
Scientists have found the first strong link in humans between a common gene and risk for the disease that leads to most heart attacks and strokes, according to results of a study by researchers at the Keck School of Medicine of the University of Southern California and the David Geffen School of Medicine at UCLA.
People with a variant form of a gene called 5-lipoxygenase (ALOX5) have a greater risk of atherosclerosis, a build-up of cholesterol in artery walls that contributes to heart disease, scientists report in the Jan. 1 issue of the New England Journal of Medicine. The high-risk form of ALOX5 occurred in about 5 percent of participants in the Los Angeles Atherosclerosis Study, which follows the cardiovascular health of 470 utility workers in Southern California.

In a joint experimental and theoretical work performed at the Heidelberg Max Planck Institute for Nuclear Physics, an international team of physicists detected for the first time an orbital crossing in the highly charged ion Pr⁹⁺. Optical spectra were recorded employing an electron beam ion trap and analysed with the aid of atomic structure calculations. A proposed nHz-wide transition has been identified and its energy was determined with high precision. Theory predicts a very high sensitivity to new physics and extremely low susceptibility to external perturbations for this “clock line” making it a unique candidate for proposed precision studies.
Laser spectroscopy of neutral atoms and singly charged ions has reached astonishing precision by merit of a chain of technological advances during the past...
The ability to investigate the dynamics of single particle at the nano-scale and femtosecond level remained an unfathomed dream for years. It was not until the dawn of the 21st century that nanotechnology and femtoscience gradually merged together and the first ultrafast microscopy of individual quantum dots (QDs) and molecules was accomplished.
Ultrafast microscopy studies entirely rely on detecting nanoparticles or single molecules with luminescence techniques, which require efficient emitters to...
Graphene, a two-dimensional structure made of carbon, is a material with excellent mechanical, electronic and optical properties. However, it did not seem suitable for magnetic applications. Together with international partners, Empa researchers have now succeeded in synthesizing a unique nanographene predicted in the 1970s, which conclusively demonstrates that carbon in very specific forms has magnetic properties that could permit future spintronic applications. The results have just been published in the renowned journal Nature Nanotechnology.
Depending on the shape and orientation of their edges, graphene nanostructures (also known as nanographenes) can have very different properties – for example,...
