Submission + - NAVSOP: A robust solution to GPS jamming? (newscientist.com)

Submitted by dangle
dangle writes: BAE Systems has developed a positioning solution that it claims will work even when GPS is unavailable. Its strategy is to use the collection of radio frequency signals from TV, radio and cellphone masts, even WiFi routers, to deduce a position.
BAE's answer is dubbed Navigation via Signals of Opportunity (NAVSOP). It interrogates the airwaves for the ID and signal strength of local digital TV and radio signals, plus air traffic control radars, with finer grained adjustments coming from cellphone masts and WiFi routers. In any given area, the TV, radio, cellphone and radar signals tend to be at constant frequencies and power levels as they are are heavily regulated — so positions could be calculated from them. "The real beauty of NAVSOP is that the infrastructure required to make it work is already in place," says a BAE spokesman — and "software defined radio" microchips that run NAVSOP routines can easily be integrated into existing satnavs. The firm believes the technology could also work in urban concrete canyons where GPS signals cannot currently reach.

Submission + - The Boy Who Loved Batman

Submitted by theodp
theodp writes: As a young boy, Batman producer Michael Uslan — a self-described 'ultimate comic book geek' — was traumatized to see the Caped Crusader being 'murdered' in front of his very eyes by the camp 60's TV series. 'I was horrified,' Uslan told a Harper College audience last week. 'I was horrified because the whole world was laughing at Batman, and that just killed me.' At that point, the 13-year-old vowed to teach the world about the Batman he knew, about the crusader who lurked in the shadows, about a darker, grittier superhero. As told in his memoir The Boy Who Loved Batman, he made good on that vow: Uslan has served as the executive producer of all Batman major motion pictures, from 1989's Batman to the upcoming The Dark Knight Rises .

Submission + - US-CERT discloses security flaw in Intel chips (csoonline.com)

Submitted by Fnord666
Fnord666 writes: The U.S. Computer Emergency Readiness Team (US-CERT) has disclosed a flaw in Intel chips that could allow hackers to gain control of Windows and other operating systems, security experts say.

The flaw was disclosed the vulnerability in a security advisory released this week. Hackers could exploit the flaw to execute malicious code with kernel privileges, said a report in the Bitdefender blog.

"Some 64-bit operating systems and virtualization software running on Intel CPU hardware are vulnerable to a local privilege escalation attack," the US-CERT advisory says. "The vulnerability may be exploited for local privilege escalation or a guest-to-host virtual machine escape."

Submission + - Sen. Rand Paul Introduces TSA Reform Legislation (senate.gov) 1

Submitted by OverTheGeicoE
OverTheGeicoE writes: Over a month after Sen. Rand Paul announced his intention to pull the plug on TSA, he has finally released his legislation that he tweets will 'abolish the #TSA & establish a passengers "Bill of Rights."' Although the tweet sounds radical, the press release describing his proposed legislation is much less so. 'Abolition' really means privatization; one of Paul's proposals would simply force all screenings to be conducted by private screeners. The proposed changes in the 'passenger Bill of Rights' appear to involve slight modifications to existing screening methods at best. Many of his 'rights' are already guaranteed under current law, like the right to opt-out of body scanning. Others can only vaguely be described as rights, like 'expansion of canine screening.' Here's to the new boss...

Submission + - Skin Cells Turned into Heart Muscle for First Time

Submitted by Anonymous Coward
An anonymous reader writes: By taking skin cells and turning them into stem cells, a technique that is already well known, researchers were able to generate beating heart cells — a medical first.

"We have shown that it's possible to take skin cells from an elderly patient with advanced heart failure and end up with his own beating cells in a laboratory dish that are healthy and young — the equivalent to the stage of his heart cells when he was just born," Lior Gepstein, study author and professor of medicine at the Technion Israel Institute of Technology in Israel.

Submission + - Groups launch $200M gigabit-per-second broadband project (networkworld.com)

Submitted by alphadogg
alphadogg writes: An Ohio startup company has raised $200 million to fund gigabit-per-second broadband projects in six university communities across the U.S., the company announced Wednesday. Gigabit Squared will work with the University Community Next Generation Innovation Project (Gig.U), a coalition of 30 universities focused on improved broadband, to select six communities in which to build the ultra-fast broadband networks, they said. The two organizations will select winning communities between November and the first quarter of 2013, Mark Ansboury, president of Gigabit Squared, said. The new project comes at an important time, when many commercial broadband providers have stopped deploying next-generation networks, said Blair Levin, executive director of Gig.U and lead author of the FCC's 2010 national broadband plan.

Submission + - Interview With Bioethicist Jonathan Moreno About Military Neuroscience (vice.com)

Submitted by
pigrabbitbear
pigrabbitbear writes: "Who’s driving a lot of neuro research? The military. Much of it is health related, like figuring out how to make prosthetics work more seamlessly and helping diagnose brain injuries. But the military’s involvement highlights the basic ethical quandary of neurological development: When our brains pretty much define who we are, what happens when you start adding tech in there? And what happens when you take it away?

Jonathan Moreno is quite possibly the top bioethicist in the country, and along with Michael Tennison, recently penned a fascinating essay on the role and ethics of using neuroscience for national security. He also recently updated his book Mind Wars, a seminal look into the military’s work with the brain. In this interview he discusses brain implants, drones, and what will happen when military tech hits the civilian world."

Submission + - Indy 500 Drivers Get Earful of MEMS Accelerometers (eetimes.com)

Submitted by Anonymous Coward
An anonymous reader writes: Believe it or not, but this weekend there will be six MEMS accelerometers inside the ears of each Indy 500 driver--three inside each ear. In the event of a crash, a black box between their legs records the G-forces exerted on the drivers head to instantly determine if the driver has a concussion. Drivers used to have to wait around to see if their head hurt after a race before going for medical help, but now concussions can be determined ahead of time so that preventative medicines can be administered to keep their brains from swelling. I knew that some of these drivers had 'big heads' but now their size is actually being measured with accelerometers :)

Submission + - Nvidia, Citrix Bringing Graphics Power to the Cloud (wired.com)

Submitted by

MikeatWired writes: "The chip giant Nvidia has combined forces with Citrix to deliver graphics processing power from the cloud. The companies have teamed up to integrate Nvidia’s new virtual GPU technology with Citrix’s XenDesktop and XenServer hypervisor desktop virtualization offering to '[extend] GPU capability beyond power users like design engineers and radiologists to other workers in the organization who need access to large 3-D models but don’t require the power of a dedicated graphics card.' But the new virtual graphics power is not quite on-demand just yet. The 3-D-capable VGX cloud platform, which holds up to four Kepler GPUs with 16GB, will only be available as joint beta trials that are not expected until the end of the year. 'Scalability of this new technology looks very promising. While GPU sharing has been available for some time with XenApp HDX 3D, it has been limited to DirectX-based applications compatible with Windows Server 2008 R2 Remote Desktop Services (RDS), with scalability of no more than 10 or 12 users per high-end graphics card,' Citrix’s Derek Thorslund writes in a blog post. This new offering runs on standard Windows 7 virtual desktops and supports both DirectX- and OpenGL-based applications, he added."

Maow writes: Despite a recent story claiming that Canada's Bill C-30, covering internet surveillance, has died a "lonely" death, the minister responsible claims otherwise.

"Public Safety Minister Vic Toews is denying reports that the Harper government intends to quietly shelve its controversial online surveillance bill, C-30. Speaking to reporters on Wednesday morning, Toews insisted the legislation was moving ahead."

This is the bill that you either support, "or you stand with the child pornographers."

techfun89 writes: "Facebook messages now feature the ability to determine if the message you sent a friend has been read.

Every message you send now has this turned on by default. The message gets marked as "seen" if the person is actively chatting or checking their messages. No matter where you send the message from, whether your phone or the web it is enabled.

This change goes along with Facebook's new privacy policy which was updated last Friday. Some may feel the added feature of message tracking is a good addition. Yet for others this brings up questions, those of privacy and also what exactly "seen" may mean."
