Studying the photochemistry has shown that ultraviolet radiation can set off harmful chemical reactions in the human body and, alternatively, can provide 'photo-protection' by dispersing extra energy. To better understand the dynamics of these photochemical processes, a group of scientists irradiated the RNA base uracil with ultraviolet light and documented its behavior on a picosecond timescale. They discuss their work this week in The Journal of Chemical Physics.
A time-resolved fluorescence resonance energy transfer-based BTK occupancy assay measures target engagement in peripheral blood mononuclear cells (PBMCs) and in lymph-node and bone-marrow samples.
A new discovery in how heart muscles maintain their shape in fruit flies sheds light on the crucial relationship between cardiac function, metabolism, and longevity. Researchers have discovered that maintaining high levels of the protein vinculin confers health benefits to fruit flies. Their work, published in APL Bioengineering, shows that fruit flies bred to produce 50 percent more vinculin enjoyed better cardiovascular health and lived a third of their average life span longer.
One object has long been known: the 13-Jupiter-mass planet beta Pictoris b, one of the first planets discovered by direct imaging, back in 2009. The new object, dubbed 2MASS 0249 c, has the same mass, brightness, and spectrum as beta Pictoris b.
A new molecule designed by University of Adelaide researchers shows great promise for future treatment of many cancers.
Researchers at Purdue University and the University of Virginia have developed a new fabrication method that makes tiny, thin-film electronic circuits peelable from a surface. The technique not only eliminates several manufacturing steps and the associated costs, but also allows any object to sense its environment or be controlled through the application of a high-tech sticker.
Defects are often observed when making borophene, the single-atom form of boron, but unlike in other two-dimensional materials, these mismatched lattices can assemble into ordered structures that preserve the material's metallic nature and electronic properties. Labs at Rice and Northwestern universities made the first detailed analysis of borophene defects.
Researchers have developed a microscopic "trampoline" that can absorb microwave energy and bounce it into laser light -- a crucial step for sending quantum signals over long distances.
Researchers at the University of Maryland (UMD), the U.S. Army Research Laboratory (ARL), and Argonne National Laboratory (ANL) have figured out how to increase a rechargeable battery's capacity by using aggressive electrodes and then stabilizing these potentially dangerous electrode materials with a highly-fluorinated electrolyte.
A new study demonstrates that a correlation also exists between cumulative carbon emissions and future sea level rise over time -- and the news isn't good.
