London Terrorist Used WhatsApp, UK Calls For Backdoors

Sun, 26 Mar 2017 20:34:00

Wednesday 52-year-old Khalid Masood "drove a rented SUV into pedestrians on Westminster Bridge before smashing it into Parliament's gates and rushing onto the grounds, where he fatally stabbed a policeman and was shot by other officers," writes the Associated Press. An anonymous reader quotes their new report:

Westminster Bridge attacker Khalid Masood sent a WhatsApp message that cannot be accessed because it was encrypted by the popular messaging service, a top British security official said Sunday. British press reports suggest Masood used the messaging service owned by Facebook just minutes before the Wednesday rampage that left three pedestrians and one police officer dead and dozens more wounded.... Home Secretary Amber Rudd used appearances on BBC and Sky News to urge WhatsApp and other encrypted services to make their platforms accessible to intelligence services and police trying to carrying out lawful eavesdropping. "We need to make sure that organizations like WhatsApp -- and there are plenty of others like that -- don't provide a secret place for terrorists to communicate with each other," she said...

Rudd also urged technology companies to do a better job at preventing the publication of material that promotes extremism. She plans to meet with firms Thursday about setting up an industry board that would take steps to make the web less useful to extremists.

New Release Of StarCraft In 4K Ultra High Definition Annouonced

Sun, 26 Mar 2017 19:34:00

The classic 90s-era videogames StarCraft and StarCraft: Brood War will be re-released this summer -- remastered in 4K Ultra High Definition. An anonymous reader quotes The Verge:

It will also include a number of updates, such as remastered sound, new additional illustrations for the campaign missions, new matchmaking capabilities, the ability to connect to Blizzard App, the ability to save to the cloud, and more... Blizzard also announced that it was issuing a new update to StarCraft: Brood War this week, which will include some bug fixes and anti-cheat measures, but will also make StarCraft Anthology (which includes StarCraft and Brood War) available to download for free.

Kotaku reports that the news was announced at this weekend's I <3 StarCraft event in South Korea, "a mini-tournament between some of the game's best players being held to honor the game's legacy."

17-Year-Old Corrects NASA Mistake In Data From The ISS

Sun, 26 Mar 2017 18:34:00

"A British teenager has contacted scientists at NASA to point out an error in a set of their own data," writes the BBC. An anonymous reader quotes their report.

A-level student Miles Soloman found that radiation sensors on the International Space Station (ISS) were recording false data... The correction was said to be "appreciated" by NASA, which invited him to help analyse the problem... The research was part of the TimPix project from the Institute for Research in Schools (IRIS), which gives students across the UK the chance to work on data from the space station, looking for anomalies and patterns that might lead to further discoveries. What Miles had noticed was that when nothing hit the detector, a negative reading was being recorded. But you cannot get negative energy... It turned out that Miles had noticed something no-one else had -- including the NASA experts. NASA said it was aware of the error, but believed it was only happening once or twice a year. Miles had found it was actually happening multiple times a day.

There's a video of the student -- and his teacher -- describing the discovery, a story which Miles says his friends at high school listen to with "a mixture of jealousy and boredom"

Aerospace Startup Will Build A Supersonic Mach 2.2 Aircraft

Sun, 26 Mar 2017 17:34:00

A new commercial aircraft will fly more than twice the speed of sound, traveling from New York to London in 3.4 hours. An anonymous reader quotes Fortune:

Colorado-based startup Boom Supersonic is one step closer to making such travel a reality after securing $33 million in investments to construct and fly its first supersonic jet, the XB-1 demonstration and testing craft, according to TechCrunch... With the new funding, Boom will be able to put that concept -- and the technology needed to power it -- to the test. "This funds our first airplane, all the way through flight tests," Boom founder and CEO Blake Scholl told TechCrunch. "Now we have all the pieces we need â" technology, suppliers and capital â" to go out and make some history and set some speed records."

They'll be testing a prototype that's one-third smaller than the commercial version within the next year.

Theranos To Investors: Please Don't Sue! Here, Have Some More Shares

Sun, 26 Mar 2017 16:34:00

Theranos "plans to give additional shares to investors who pledge not to sue," reports the Wall Street Journal. An anonymous reader quotes Silicon Beat: The deal, which hasn't been disclosed publicly, was approved by the Palo Alto-based company's board last month, The Wall Street Journal reported, citing anonymous "people familiar with the matter." They said most investors have tentatively agreed to the deal. Those extra shares are coming from none other than founder and CEO Elizabeth Holmes' personal cache, the Journal reported. That means the beleaguered founder, who has remained stubbornly at the helm of her struggling startup even though federal regulators have barred her from running a medical lab for two years, would give up her majority ownership in the company.
