A case of reinfection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is described in a study published online Oct. 12 in The Lancet Infectious Diseases.

For 44 years, before it was imploded to make way for the Venetian, the Sands ruled the Strip. From 1952 to 1996, the glamorous casino was at the center of Las Vegas’ constant evolution, hosting the likes of John F. Kennedy and the Rat Pack. In his new book, At the Sands: The Casino That Shaped Classic Las Vegas, Brought the Rat Pack Together, and Went Out With a Bang, Las Vegas historian David G. Schwartz chronicles the days of the illustrious resort.

Developing materials that are superconducting—without electrical resistance and expulsion of magnetic field at room temperature—is the “holy grail” of condensed matter physics, says Ranga Dias, an assistant professor of mechanical engineering and of physics and astronomy at the University of Rochester.

As Chicago weighs a school reopening plan for the year’s second quarter, one thing is conspicuously absent: an agreement with the city’s restive and powerful teachers union.

After years and years of work, we are finally here. A team of researchers from the University of Rochester in New York has just synthesized the first superconducting material , a mix of hydrogen, carbon and sulfur, which manages to show its special characteristics even at room temperature . A tool, therefore, that could revolutionize the world of technology and electronics, with significant benefits both in terms of costs and environmental. “Sought after for more than a century,” comments study author Ranga Dias , “these materials are sure to change the world as we know it. Our discovery will open the door to many potential applications ” . The studyhas just been published in Nature.

A superconducting material allows electrical current to flow through it with perfect efficiency, without wasting energy.

For decades, physicists have dreamed of discovering a material that could effortlessly convey electricity at everyday temperatures, a feat that would save gargantuan amounts of energy and revolutionize modern technology.

For the first time ever, scientists have demonstrated that superconductivity, a state that enables electrical charges to pass through materials with no resistance, is possible at room temperature.
