Toward more efficient computing, with magnetic waves

by Rob Matheson, MIT News

Circuit design offers a path to “spintronic” devices that use little electricity and generate practically no heat.

MIT researchers have devised a novel circuit design that enables precise control of computing with magnetic waves — with no electricity needed. The advance takes a step toward practical magnetic-based devices, which have the potential to compute far more efficiently than electronics.

Indian student creates a brick made from recycled plastic

by Anna Fletcher, CNN

When an Indian engineering student visited a traditional brick kiln, he was appalled at what he saw.

“My moment of reckoning came during that field trip,” says Abhishek Banerjee, recalling the 2016 visit. “We saw that the workers there were being treated very inhumanely. And the working conditions of that brick kiln were very improper — people were digging clay with their bare hands.”

Bad RCS implementations are creating big vulnerabilities, security researchers claim

by Jon Porter, The Verge

Carriers are creating problems for users.

Security researchers at SRLabs have found a number of vulnerabilities with the way carriers around the world are implementing RCS, the new messaging standard designed to replace SMS, Motherboard reports. In some cases, these issues could compromise a user’s location data, they could allow their text messages or calls to be intercepted, or they might allow their phone number to be spoofed.

UN: The world has backed itself into a treacherous corner on climate change

by Umair Irfan, VOX

Countries are far off course in meeting emissions goals. More drastic actions are needed to get back on track.

The world is further off course than ever from meeting the goals of the Paris climate agreement and averting climate catastrophe as the divide between countries’ pledges and actions continues to grow.

The Flying Taxi future is coming, but it’s Elitist and Underwhelming

by Alexis Ong, The Verge

German startup Volocopter unveiled a new flying taxi station in Singapore, but it was gone within a week.

On the bright Monday morning of October 21st in downtown Singapore, German air taxi startup Volocopter unveiled the VoloPort, the world’s first flying taxi station. Perched atop a floating platform at Marina Bay, the temporary structure offered a generous view of the country’s central business district’s most iconic landmarks. The press event went off without a hitch, though from the lingering construction crew, it was clear that this had been an 11th-hour effort.
