New ‘Spray-On’ Memory Could Turn Everyday Items Into Digital Storage Devices

Researchers at Duke University have developed “spray-on” digital memory using only an aerosol jet printer and nanoparticle inks. An anonymous reader quotes Duke Today: The device, which is analogous to a 4-bit flash drive, is the first fully-printed digital memory that would be suitable for practical use in simple electronics such as environmental sensors or RFID tags. And because it is jet-printed at relatively low temperatures, it could be used to build programmable electronic devices on bendable materials like paper, plastic or fabric… The new material, made of silica-coated copper nanowires encased in a polymer matrix, encodes information not in states of charge but instead in states of resistance. By applying a small voltage, it can be switched between a state of high resistance, which stops electric current, and a state of low resistance, which allows current to flow. And, unlike silicon, the nanowires and the polymer can be dissolved in methanol, creating a liquid that can be sprayed through the nozzle of a printer. Amazingly, its write speed is three microseconds, “rivaling the speed of flash drives.” The information can be re-written many times, and the stored data can last for up to 10 years.

US Hacker Sets Off 156 Sirens At Midnight

“I had the displeasure of being awoken at midnight to the sounds of civil-defense/air-raid sirens, ” writes very-long-time Slashdot reader SigIO, blaming “some schmuck with a twisted sense of humor.” The Dallas News reports: Rocky Vaz, director of Dallas’ Office of Emergency Management, said that all 156 of the city’s sirens were activated more than a dozen times… Dallas officials blame computer hacking for setting off emergency sirens throughout the city early Saturday… It took until about 1:20 a.m. to silence them for good because the emergency system had to be deactivated. The system remained shut down Saturday while crews safeguarded it from another hack. The city has figured out how the emergency system was compromised and is working to prevent it from happening again, he said… The city said the system should be restored Sunday or Monday. City officials reported 4, 400 calls to their 9-1-1 emergency phone number in the first four hours of Saturday morning, with over 800 occurring in that first 15 minutes when all 156 sirens started going off simultaneously.

Google Accused of ‘Extreme’ Gender Pay Discrimination By US Labor Department

The U.S. Department of Labor is accusing Google of discriminating against its female employees and violating federal employment laws with its salaries for women. “We found systemic compensation disparities against women pretty much across the entire workforce, ” Janette Wipper, a Department of Labor regional director, testified in court in San Francisco on Friday. The Guardian reports: Google strongly denied the accusations of inequities, claiming it did not have a gender pay gap. The allegations emerged at a hearing in federal court as part of a lawsuit the DoL filed against Google in January, seeking to compel the company to provide salary data and documents to the government. Google is a federal contractor, which means it is required to allow the DoL to inspect and copy records and information about its its compliance with equal opportunity laws. Last year, the department’s office of federal contract compliance programs requested job and salary history for Google employees, along with names and contact information, as part of the compliance review. Google, however, repeatedly refused to hand over the data, which was a violation of its contractual obligations with the federal government, according to the DoL’s lawsuit. Labor officials detailed the government’s discrimination claims against Google at the Friday hearing while making the case for why the company should be forced to comply with the DoL’s requests for documents. Wipper said the department found pay disparities in a 2015 snapshot of salaries and said officials needed earlier compensation data to evaluate the root of the problem and needed to be able to confidentially interview employees.

This Tricorder-Like Device Can Tell if Your Brain Is Bleeding

Following a head injury, patients typically undergo a CT scan to rule out brain bleeding. A new head worn device that scans the brain’s electrical patterns has shown tremendous promise in clinical trials, presenting an inexpensive way for physicians to make a potentially life-saving diagnosis.

The iPhone 7 Has Arbitrary Software Locks That Prevent Repair

Jason Koebler, reporting for Motherboard: Apple has taken new and extreme measures to make the iPhone unrepairable. The company is now using software locks to prevent independent repair of specific parts of the phone. Specifically, the home buttons of the iPhone 7 and iPhone 7 Plus are not user replaceable, raising questions about both the future repairability of Apple products and the future of the thriving independent repair industry. The iPhone 7 home button will only work with the original home button that it was shipped with; if it breaks and needs to be replaced, a new one will only work if it is “recalibrated” in an Apple Store.

Public Crowd-sourcing Finds New Exoplanets

brindafella writes: A participant in a TV program “Stargazing Live” on Australia’s ABC TV channel has found four planets closely orbiting a star, using an online database. Astrophysicist Dr Chris Lintott, the principal investigator of Zooniverse, reported on Thursday’s show that four “Super Earth” planets had been identified in the data. They orbit closer to their star than Mercury does to our Sun. The person responsible for the find, Andrew Grey, is a mechanic by day and amateur astronomer in his spare time, and lives in the city of Darwin, Northern Territory. The data is sourced from NASA’s Kepler Space Telescope. “Stargazing Live” host Professor Brian Cox said he could not be more excited about the discovery. “In the seven years I’ve been making Stargazing Live this is the most significant scientific discovery we’ve ever made. The results are astonishing.” Read more of this story at Slashdot.

New Destructive Malware Intentionally Bricks IoT Devices

An anonymous reader writes: “A new malware strain called BrickerBot is intentionally bricking Internet of Things (IoT) devices around the world by corrupting their flash storage capability and reconfiguring kernel parameters. The malware spreads by launching brute-force attacks on IoT (BusyBox-based) devices with open Telnet ports. After BrickerBot attacks, device owners often have to reinstall the device’s firmware, or in some cases, replace the device entirely. Attacks started on March 20, and two versions have been seen. One malware strain launches attacks from hijacked Ubiquiti devices, while the second, more advanced, is hidden behind Tor exit nodes. Several security researchers believe this is the work of an internet vigilante fed up with the amount of insecure IoT devices connected to the internet and used for DDoS attacks. “Wow. That’s pretty nasty, ” said Cybereason security researcher Amit Serper after Bleeping Computer showed him Radware’s security alert. “They’re just bricking it for the sake of bricking it. [They’re] deliberately destroying the device.” Read more of this story at Slashdot.
