This New Incandescent Bulb Uses Nano Mirrors to Match LED Bulb Efficiency

Energy-saving bulbs may have some competition in the shape of an ageing technology. Scientists have developed a new kind of incandescent light bulb that uses modern science to ramp up its efficiency, almost matching that of commercial LED bulbs. Read more…

Police claim to have cracked extra-secure BlackBerry phones

BlackBerry smartphones have secure messaging as a matter of course, but for some that isn’t enough: there are custom models that are even more secure thanks to PGP-encrypted mail. However, it seems that these locked down models aren’t quite as safe as you’d think. The Netherlands Forensic Institute has confirmed a recent report that it’s capable of scooping up encrypted data from PGP-equipped BlackBerry devices. It’s not discussing the exact techniques involved, but it’s relying on a tool from CelleBrite to get the job done. One possibility is that investigators are guessing the password based on a memory dump, although that normally requires yanking a memory chip off the phone’s motherboard. If it’s any consolation, police need physical access to crack these BlackBerrys. Their methods also aren’t completely reliable (a small batch couldn’t be cracked), and it’s uncertain that this will work with every single PGP implementation. GhostPGP, for instance, claims that it’s unaffected. All the same, this isn’t very comforting if you bought a customized BlackBerry with the promise of airtight security. And there’s no certainty that only Dutch cops have access — it’s entirely possible that other law enforcement and surveillance agencies know these tricks.

Ars talks self-driving car technology with Ford at CES

Wayne Williams from Ford shows us one of the company’s fully autonomous Fusion research vehicles. Video shot/edited by Nathan Fitch. (video link) LAS VEGAS—As we’ve noted elsewhere, CES has now evolved to be part car show. But not just any car show—the focus is on how technology is transforming the car, and nowhere is that more evident than in autonomous driving. The goal is to get to “level four”—the National Highway Traffic Safety Administration’s highest level of self-driving vehicle, capable of getting from point A to point B without any human driver intervention. We’re not there yet—no one in the industry Ars has spoken to recently thinks the tech challenges are quite solved yet—but research vehicles from companies like Google , Delphi , Audi , and Ford are testing out the hardware and software necessary to get us to that point. With that in mind, we spoke to Wayne Williams, who gave us a quick tour of one of Ford’s fully autonomous hybrid Fusions. Read 5 remaining paragraphs | Comments

Rumors Are Flying That We Finally Found Gravitational Waves 

Excited rumors began circulating on Twitter this morning that a major experiment designed to hunt for gravitational waves —ripples in the fabric of spacetime first predicted by Albert Einstein—has observed them directly for the very first time. If confirmed, this would be one of the most significant physics discoveries of the last century. Read more…

RIP David Bowie, The Man Who Changed Science Fiction

David Bowie, who just died of cancer aged 69 , had an incalculable impact on pop culture throughout his shape-shifting career. But perhaps more than any other musician, he also had a tremendous impact on science fiction. He changed the way we thought about the alien, the uncanny, and the familiar. Read more…

Scientists find a way to make concrete on Mars

If humans are ever going to have a long-term presence on Mars , they’ll need to make their own buildings — they can’t count on timely shipments from Earth. But how do they do that when the resources they have will share little in common with what they knew back home? Northwestern University researchers have an idea. They’ve developed a concrete that uses Mars’ native materials. You only have to heat sulphur until it melts, mix it with an equal part of Martian soil and let it cool. The finished concrete is very strong, easy to work with and recyclable — you just have to reheat it to get some building supplies back. Any need for Martian concrete is years away at best , but the discovery is still crucial. It suggests that explorers won’t have much trouble transitioning from short-term shelters to more permanent structures. Also, any would-be settlers can afford to pack light. Rather than carry every possible building they might want, they could bring just the essentials and build more once they’re established on the Red Planet’s surface.

New York City’s whole subway system gets WiFi in 2016

Forget having to remember which New York City subway stations have WiFi — by the end of this year, you won’t have to pick and choose. State governor Andrew Cuomo has promised that every underground station will get WiFi by the end of the year, guaranteeing at least some kind of internet access while you’re waiting for your train. Complete cellular service will come slightly later, with end-to-end access ready by early 2017. Either is heartening news if you regularly commute underground, since Transit Wireless (which is handling the service) had previously targeted late 2017 for full WiFi service. There should be more in the works, too. Cuomo has proposed a contactless payment system that would let you use your smartphone or newer bank cards to pay your fare, rather than busting out your MetroCard or some tickets. The current proposed phone system looks a bit clunky with its QR-based scanning, but NYC buses and subways won’t get this feature until 2018 — hopefully, it’ll include NFC-based payments (such as Apple Pay or Android Pay) by then. Both the Long Island Rail Road and Metro-North Railroad will have mobile ticketing within half a year. And yes, the city plans to drag trains (and buses) into the modern era. You’ll get real-time arrival data for all subway lines, and more countdown clocks. Also, subway cars will start getting USB charging ports this year (400 will have them by next year), and every new bus delivered from this year forward will have WiFi hotspots. In short, NYC’s mass transit system will soon revolve around mobile. While there will still be gaps in coverage (most notably when you’re in the middle of some tunnels), they may soon become the exception rather than the rule.
