Researchers Finally Create Metal Wires Made from Carbon
University of California at Berkeley has made a big announcement: Transistors based on carbon rather than silicon could potentially boost computers’ speed and cut their power consumption more than a thousandfold — think of a mobile phone that holds its charge for months — but the set of tools needed to build working carbon circuits has remained incomplete until now. A…

Hydrogen and Carbon Capture Tech Are Key To Net-Zero US Electricity, Study Says
The United States can generate affordable electricity without producing carbon dioxide emissions by 2035 by deploying hydrogen or carbon capture technology, according to a report released on Wednesday by a climate policy think tank. Reuters reports: The report by California-based Energy Innovatihere which researches ways to combat global warming, highlighted five scenarios for the United States to generate 100% clean energy…
A New Theory Asks: Could a Mask Be a Crude ‘Vaccine’?
Iwastheone shares a report from The New York Times: As the world awaits the arrival of a safe and effective coronavirus vaccine, a team of researchers has come forward with a provocative new theory: that masks might help to crudely immunize some people against the virus. The unproven idea, described in a commentary published Tuesday in the New England Journal of…
The true polar wander of Jupiter’s moon Europa
Cracks in Europa’s surface indicate the moon’s outer ice shell has shifted by as much as 70 degrees over the past several million years. It’s the kind of movement you’d expect from a planetary crust floating on a subsurface ocean. Source: https://earthsky.org/space/europa-ice-shell-70-degree-shift-true-polar-wander…
