Metamaterial Superconductor Hints At New Era of High Temperature Superconductors

3 hours 47 min ago
KentuckyFC writes: Superconductors allow current to flow with zero resistance when cooled below some critical temperature. They are the crucial ingredients in everything from high-power magnets and MRI machines to highly sensitive magnetometers and magnetic levitation devices. But one big problem is that superconductors work only at very low temperatures — the highest is around 150 kelvin (-120 degrees centigrade). So scientists would dearly love to find ways of raising this critical temperature. Now a group of physicists say they've found a promising approach: to build metamaterial superconductors that steer electrons in the same way as other metamaterials steer light to create invisibility cloaks. The inspiration for the work comes from the observation that some high temperature superconductors consist of repeated layers of conducting and dielectric structures. So the team mixed tin — a superconductor at 3.7 kelvin — with the dielectric barium titanate and found that it raised the critical temperature by 0.15 kelvin. That's the first demonstration that superconductors can be thought of as metamaterials. With this proof of principle under their belts, the next step is to look for bigger gains at higher temperatures.

Ask Slashdot: What Do You Wish You'd Known Starting Out As a Programmer?

What advice might we give to our younger self, or to younger selves coming to programming just now? Andrew C. Oliver offers several insights he gave little thought to when first coding: "Back then, I simply loved to code and could have cared less about my 'career' or about playing well with others. I could have saved myself a ton of trouble if I'd just followed a few simple practices." What are yours?

Experimental Drug Stops Ebola-like Infection

5 hours 11 min ago
sciencehabit writes: An experimental treatment against an Ebola-related virus can protect monkeys even when given up to 3 days after infection, the point at which they show the first signs of disease. The virus, known as Marburg, causes severe hemorrhagic fever—vomiting, diarrhea, and internal bleeding. In one outbreak, it killed 90% of people it infected. There are no proven treatments or vaccines against it. The new results raise hopes that the treatment might be useful for human patients even if they don't receive it until well after infection. The company that makes the compound, Tekmira, based in Burnaby, Canada, has started a human safety trial of a related drug to treat Ebola virus disease, and researchers hope that it, too, might offer protection even after a patient has started to feel ill. In other Ebola news, the two American aid workers who were infected with the virus while in Liberia have now recovered and been released from the hospital.

Dramatic Shifts In Manufacturing Costs Are Driving Companies To US, Mexico

5 hours 44 min ago
hackingbear writes: According to a new Cost-Competitiveness Index, the nations often perceived as having low manufacturing costs — such as China, Brazil, Russia, and the Czech Republic — are no longer much cheaper than the U.S. In some cases, they are estimated to be even more expensive. Chinese manufacturing wages have nearly quintupled since 2004, while Mexican wages have risen by less than 50 percent in U.S. dollar terms, contrary to our long-standing misconception that their labors were being slaved. In the same period, the U.S. wage is essentially flat, whereas Mexican wages have risen only 67%. Not all countries are taking full advantage of their low-cost advantages, however. The report found that global competiveness in manufacturing is undermined in nations such as India and Indonesia by several factors, including logistics, the overall ease of doing business, and inflexible labor markets.

Couchsurfing Hacked, Sends Airbnb Prank Spam

7 hours 8 min ago
Slashdot regular (and Couchsurfing.org volunteer) Bennett Haselton writes with a report that an anonymous prankster hacked the Couchsurfing.org website and sent spam to about 1 million members, snarkily advertising their commercial arch-rival Airbnb as "the new Couchsurfing." (Read on below for more on the breach.) As of now, the spam's been caught, but not the spammer.
