MIT Professor Charged With Hiding Work For China

A Massachusetts Institute of Technology professor was charged Thursday with hiding work he did for the Chinese government while he was also collecting U.S. dollars for his nanotechnology research. The Associate Press reports: Gang Chen, 56, was arrested by federal agents at his home in Cambridge on charges including wire fraud, officials said. While working for MIT, Chen entered into undisclosed…

Scientists Slow Down and Steer Light With Resonant Nanoantennas

New submitter HotSyncer shares a report from Phys.Org: [I]n a paper published on Aug. 17, in Nature Nanotechnology, Stanford scientists demonstrate a new approach to slow light significantly, much like an echo chamber holds onto sound, and to direct it at will. Researchers in the lab of Jennifer Dionne, associate professor of materials science and engineering at Stanford, structured ultrathin silicon…

Russia Spreads Conspiracy Theory Linking Coronavirus Pandemic to Bill Gates

Wired investigated the vast spread of 5G/coronavirus conspiracy theories — and reports that “Amongst the conspiracy sludge, one voice stands out.” “For more than a year, propaganda broadcaster RT has been attacking the roll-out of 5G.”
While RT has never outright linked 5G to coronavirus, it has played a role in adding legitimacy to conspiracy theories surrounding the technology. As The New…

First intrinsic magnetic topological insulator discovered

The so-called topological insulators are those materials that are insulators in bulk, i.e., those that do not allow electric currents in their volume, but that are conductors on their surfaces. Unlike the usual conductors, that is, metals, the electric current circulating in a topological insulator does not suffer any loss of energy. This property opens great possibilities for application in electronics,…

Ultrafast stimulated emission microscopy of single nanocrystals

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…

Amazon Plans $800 Million Data Center In Argentina

Amazon’s cloud division plans to build a regional data center in a free-trade zone in Argentina. Bloomberg reports: The Seattle-based company is preparing to invest about $800 million in the project over 10 years and will reap considerable tax benefits by locating the data center in the Bahia Blanca-Coronel Rosales districts of the province of Buenos Aires, [said people familiar with…

DNA Data Storage Is Closer Than You Think

“Life’s information-storage system is being adapted to handle massive amounts of information,” reports Scientific American, reports Scientific American, calling it “an alternative to hard drives” and noting that DNA “is already routinely sequenced (read), synthesized (written to) and accurately copied with ease. “DNA is also incredibly stable, as has been demonstrated by the complete genome sequencing of a fossil horse that…
