Here’s a fun video showing the rainbow of colors that anodized titanium can become. There are blues and purples and gold and it all changes so fast. It’s basically magic (or science!) that just applying voltage to a piece of titanium in an electrolytic bath can transform the color completely. Read more…

ememisya writes: I wonder if I posted, “There will be another 12/7 tomorrow, just a warning.” around December, would people associate it with Pearl Harbor and I would find myself arrested, or has enough time passed for people to not look at the numbers 12 and 7 and take a knee jerk reaction? A student was arrested for “Harassment by Computer” (a class 1 misdemeanor in the state of Virginia) due to his post on an “anonymous” website [Yik Yak]. Although the post in and of itself doesn’t mean anything to most people in the nation, it managed to scare enough people locally for law enforcement agencies to issue a warrant for his arrest. “Moon, a 21-year-old senior majoring in business information technology, is being charged with Harassment by Computer, which is a class one misdemeanor. Tuesday night, April 28, a threat to the Virginia Tech community was posted on the anonymous social media app Yik Yak. Around 11:15 p.m., an unknown user posted ‘Another 4.16 moment is going to happen tomorrow. Just a warning (sic).’ The Virginia Tech Police Department released a crime alert statement Wednesday morning via email informing students that VTPD was conducting an investigation throughout the night in conjunction with the Blacksburg Police Department.” Read more of this story at Slashdot.

This might look unlike most cockroaches you’ve ever seen—but that’s because it was probably quite a lot more aggressive than any you’ve seen, too. It had to be, because, it likely survived by hunting (admittedly quite small) prey, some 100 million years ago. Read more…

Last year, NASA’s advanced propulsion research wing made headlines by announcing the successful test of a physics-defying electromagnetic drive , or EM drive. Now, this futuristic engine, which could in theory propel objects to near-relativistic speeds, has been shown to work inside a space-like vacuum. Read more…

schwit1 writes: The Russians have declared lost the Progress freighter that had been launched to the ISS yesterday. They never could regain control of the craft, plus it was in an incorrect orbit. Moreover, the U.S. Air Force has detected debris nearby, suggesting a significant failure of some kind. The Russians are now considering delaying the next manned launch, scheduled for May 26, while they investigate this failure. Both Soyuz and Progress use some of the same systems, including the radar system that failed on Progress, and they want to make sure the problem won’t pop up on the manned mission. At the same time, they are also considering advancing the launch date of the next Progress to ISS from August 6. Based on these reports, I think they might swap the launch dates for the two flights. A Dragon is scheduled to go to ISS in between these missions, though that schedule could be changed as well to accommodate the Russian plans. Read more of this story at Slashdot.

mpicpp sends this report from The Independent: The United States Department of Defense has carried out what it says is its most successful test yet of a bullet that can steer itself towards moving targets. Experienced testers have used the technology to hit targets that were actively evading the shot, and even novices that were using the system for the first time were able to hit moving targets. The project, which is known as Extreme Accuracy Tasked Ordnance weapon, or Exacto, is being made for the American government’s military research agency, DARPA. It is thought to use small fins that shoot out of the bullet and re-direct its path, but the U.S. has not disclosed how it works. Technology in the bullet allows it to compensate for weather and wind, as well as the movement of people it is being fired at, and curve itself in the air as it heads towards its target.

An anonymous reader writes: The Electronic Frontier Foundation is warning against a new potential privacy threat: cameras that look inside cars and try to identify how many people are inside. This technology is a natural combination of simpler ones that have existed for years: basic object recognition software and road-side cameras (red light cameras, speeding cameras, license plate readers — you name it). Of course, we can extrapolate just a bit further, and point out that as soon as the cameras have high enough resolution, they can start running face recognition algorithms on the images, and determine the identities of a vehicle’s occupants. “The San Diego Association of Governments (SANDAG), a government umbrella group that develops transportation and public safety initiatives across the San Diego County region, estimates that 15% of drivers in High Occupancy Vehicle (HOV) lanes aren’t supposed to be there. After coming up short with earlier experimental projects, the agency is now testing a brand new technology to crack down on carpool-lane scofflaws on the I-15 freeway. … In short: the technology is looking at your image, the image of the people you’re with, your location, and your license plate. (SANDAG told CBS the systems will not be storing license plate data during the trial phase and the system will, at least for now, automatically redact images of drivers and passengers. Xerox’s software, however, allows police the option of using a weaker form of redaction that can be reversed on request.)” Read more of this story at Slashdot.

citpyrc writes: TeslaCrypt, the latest-and-greatest ransomware branch off of the CryptoWall family, claims to the unwitting user that his/her documents are encrypted with “a unique public key generated for this computer”. This coudn’t be farther from truth. In actuality, the developers of this malware appear to have been lazy and implemented encryption using symmetric AES256 with a decryption key generated on the user’s machine. If any of your machines are afflicted, Talos has developed a tool that can be used to generate the user’s machine’s symmetric key and decrypt all of the ransomed files.

journovampire writes: Pandora has revealed that it’s paying a 10, 000th of a dollar more to music labels and artists than it was in 2014. From the article: “Pandora has revealed that its royalty payments to SoundExchange, the US licensing body which collects performance royalties on behalf of record labels and artists, have just increased by 8%. The news was confirmed in a call with investors following Pandora’s Q1 fiscal results announcement on Thursday (April 23), in which it posted a three-month net loss of $48.3m. In what Pandora CEO Brian McAndrews called a scheduled annual step-up, Pandora has from January 1 been paying out an average $0.0014 per ad-funded stream and $0.0024 per premium stream to SoundExchange.” Read more of this story at Slashdot.
