Long-time Slashdot reader hankwang writes: The New York Times has an article on how the transmission of Covid-19 by seemingly healthy individuals was discovered in Germany on January 27, but the report was discredited because of a quibble over whether it was really asymptomatic or rather presymptomatic or oligosymptomatic transmission. Oligosymptomatic means that the symptoms are so mild that they are…

Hope diamond formed stunningly close to Earth’s core
Most diamonds originate at the bottoms of tectonic plates. But the giant blue Hope and Cullinan diamonds may have originated far deeper within the planet. Source: https://www.livescience.com/hope-cullinan-diamonds-deep-origins.html
Single-spin electron paramagnetic resonance spectrum with kilohertz spectral resolution
A high-resolution paramagnetic resonance detection method based on the diamond nitrogen-vacancy (NV) color center quantum sensor was proposed and experimentally implemented in a study led by academician DU Jiangfeng from CAS Key Laboratory of Microscale Magnetic Resonance of University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS). …
Never-Before-Seen ‘Black Nitrogen’ Plugs Puzzle in Periodic Table
Researchers at the University of Bayreuth have created a form of nitrogen that’s never been seen before. Nicknamed “black nitrogen,” the new substance is crystalline, occurs in two-dimensional sheets, and could one day be useful in advanced electronics. From a report: Strangely enough, the idea that black nitrogen didn’t exist has long been considered a mystery. The periodic table is arranged…
Manufacturing-friendly SiC boasts quantum credentials at telecom wavelengths
Decoherence is the bane of quantum technologies. In coherent systems, the phase of the wave functions representing the quantum states of particles in the system have definite relations between each other. This allows quantum devices to operate in a meaningful way that differs from classical devices. However, interacting with the world around us rapidly leads to decoherence, which makes it harder…
Will Comic Books Survive Coronavirus?
As Marvel cuts staff and publishers stop selling new titles, artists, shop owners and writers worry for the future of an industry worth billions. From a report: There are no new comic books. Steve Geppi, head of Diamond Comic Distributors, which distributes nearly every comic sold in the anglophone world (or used to), announced this on 23 March, though senior industry…

Novel method for easier scaling of quantum devices
In an advance that may help researchers scale up quantum devices, an MIT team has developed a method to “recruit” neighboring quantum bits made of nanoscale defects in diamond, so that instead of causing disruptions they help carry out quantum operations. …
Trump Puts Mike Pence In Charge of Response To Coronavirus, Says US Risk ‘Remains Very Low’
Vice President Mike Pence will be put in charge of the U.S. response to the deadly coronavirus outbreak, President Donald Trump announced Wednesday in an address from the White House. CNBC reports: Trump, in a rare appearance in the White House briefing room, maintained that the risk to the U.S. from the virus “remains very low,” amid global fears that a…
