Prof. Leonid Shvartsman and Prof. Boris Laikhtman of the university’s Racah Institute of Physics have invented a novel design of TeraHertz-ray (T-ray) lasers. They said the novel device will have 400 times higher “gain” (a measure of power) than that of the only coherent T-ray sources existing today, called THzQuantum cascade lasers. “The novel method …
Carnegie Mellon University is developing microwave-assisted magnetic recording (MAMR) technique he believes will pack three terabits of data in a square inch of a spinning disk. The next big shift in hard disk technology expected to emerge in the next year or two. Seagate Technology has been championing an approach called heat-assisted magnetic recording (HAMR) …

Department of Energy’s Pacific Northwest National Laboratory’s Gary Yang and colleagues added graphene, sheets made up of single carbon atoms, …
Two 5-10 nanometer dimers are put together. Single dots of that size put together to form pairs of dots Using DNA to assemble nanoclusters: (a) (1) DNA linker strands (squiggly lines) are used to attach DNA-coated nanoparticles to a surface. (2) Linker strands are attached to the top side of the nanoparticle. (b) (3a) A …
The Economist reviews how China is handling the current crisis. China is taking advantage of some opportunities to gain some more influence at an affordable cost by trading investment and money for more influence.

Here is a 12 page pdf with supplemental information to the research paper on “Lesion Mapping of Cognitive Abilities Linked to Intelligence”. They identified the parts of the brain that are used for verbal comprehension, perceptual organization, working memory and processing speed. The Wechsler Adult Intelligence Scale (WAIS) assesses a wide range of cognitive abilities …

In the picture, cells infected with the new virus have been stained using antibodies. After several other identification techniques failed, the new sequencing approach was used to discover a never-before-seen virus that was likely responsible for the deaths of three transplant patients who received organs from the same donor. As many as 40 percent of …
