An ultracompact beamsplitter – the smallest one in the world – has been designed and fabricated by researchers in the US. Using a newly developed algorithm, the team built the smallest integrated polarization beamsplitter to date, which could allow computers and mobile devices of the future to function millions of times faster than current machines.

Millions of routers and other embedded devices are affected by a serious vulnerability that could allow hackers to compromise them. The vulnerability is located in a service called NetUSB, which lets devices connected over USB to a computer be shared with other machines on a local network or the Internet via IP (Internet Protocol). The shared devices can be printers, webcams, thumb drives, external hard disks and more. NetUSB is implemented in Linux-based embedded systems, such as routers, as a kernel driver. The driver is developed by Taiwan-based KCodes Technology. Once enabled, it opens a server that listens on TCP...

University of Utah engineers have taken a step forward in creating the next generation of computers and mobile devices capable of speeds millions of times faster than current machines. The Utah engineers have developed an ultracompact beamsplitter—the smallest on record—for dividing light waves into two separate channels of information. The device brings researchers closer to producing silicon photonic chips that compute and shuttle data with light instead of electrons. Electrical and computer engineering associate professor Rajesh Menon and colleagues describe their invention today in the journal Nature Photonics. Silicon photonics could significantly increase the power and speed of machines such...

Such glitches emerge with surprising frequency. It’s suspected that the reason why Nasa lost contact with the Deep Impact space probe in 2013 was an integer limit being reached. And just last week it was reported that Boeing 787 aircraft may suffer from a similar issue. The control unit managing the delivery of power to the plane’s engines will automatically enter a failsafe mode – and shut down the engines – if it has been left on for over 248 days. Hypothetically, the engines could suddenly halt even in mid-flight. The Federal Aviation Administration’s directive on the matter states that...

Racing across the U.S. in your taco truck, you must fight off animals mutated by fallout from a nuclear war, and you must also turn them into delicious filling for the tacos you sell inside fortified towns. Your mission: Make it to the Canadian city of Winnipeg. You are “Gunman Taco Truck.” “It’s pretty much only a game that a kid would come up with,” says Brenda Romero, a videogame designer for more than 30 years and the mother of Donovan Romero-Brathwaite, the 10-year-old inventor of the game. And yet GTT already has been licensed by a videogame publisher for...

The US military is in danger of losing its technological advantage unless it invests in research and finds ways to build innovative weapons much faster, top officials said Thursday. The Pentagon unveiled an initiative to streamline its bureaucracy and tap into technological breakthroughs in the private sector amid growing anxiety that American forces' longtime hi-tech edge is slipping away. The measures reflected "an overriding concern that our technological superiority is at risk," Frank Kendall, the Pentagon's chief weapons buyer, wrote in a report. "Potential adversaries are challenging the US lead in conventional military capability in ways not seen since the...

Late last month a mysterious patch suddenly appeared as an Optional entry in the Windows Automatic Update chute. At the time I wrote: Conjecture at this point: It's somehow related to the ability to upgrade directly from Windows 7 or 8 to Windows 10. But of course, the official documentation doesn't say anything of the sort. The crows have come home to roost and, thanks to a German researcher named Gerard Himmelein at heise.de, we now have a more thorough understanding of exactly what Microsoft's dishing out (a Google English translation of the post is available). Yesterday Jan Willem Aldershoff...

Electric carmaker Tesla announced Friday it delivered a "record" number of vehicles in the first quarter, as it began more timely reporting of sales figures. The California firm started by tech entrepreneur Elon Musk said it sold 10,030 cars in the first three months of 2015. "This was a new company record for the most cars delivered in a quarter and represents a 55 percent increase over the first quarter last year," the company said in a statement. Going forward, Tesla said it would publish the number of new car deliveries within three days of quarter end. "We have decided...

Imagine you need to have an almost exact copy of an object. Now imagine that you can just pull your smartphone out of your pocket, take a snapshot with its integrated 3-D imager, send it to your 3-D printer, and within minutes you have reproduced a replica accurate to within microns of the original object. This feat may soon be possible because of a tiny new, tiny high-resolution 3-D imager developed at Caltech. Any time you want to make an exact copy of an object with a 3-D printer, the first step is to produce a high-resolution scan of the...

Quad High-Definition. That's a phrase you're likely to see more and more of this year, as Seoul, Korea-based LG Display announced Friday it is launching a 5.5-inch QHD LCD panel for smartphones. So what? This launch, said LG Display, happens to represent "a quantum jump" in color gamut, brightness and contrast ratio, touch function, power consumption and thinness. The company's high color gamut technology can provide more accurate colors in red and green; LG Display reported a 20 percent improvement in color gamut with this technology. The display provides a 120 percent color gamut, exceeding the 100 percent gamut offered...

About three days after it received a lavish new funding round, Meerkat died an ugly and embarrassing death. It is hard to decide whether the Great Meerkat Debacle that has unfolded over the past week is a tragedy or a comedy — probably a bit of both. The mobile streaming app that had whipped U.S. tech journalists into a frenzy announced $14 million in new funding on Thursday. Money poured in from Jared Leto, Greylock Partners and other illustrious sources. On the same day, Twitter launched its rival streaming app called Periscope. Apparently, investors didn’t stop to ponder why Meerkat...

On March 4, a woman in Mariposa County, about 70 miles north of Fresno, reported several items stolen from her home, including a smart TV, a Wi-Fi Blu-ray, laptop computer, wires and a surround sound system, the Mariposa County Sheriff's Office said Friday. A few days later, the woman discovered that movies were being watched on her Netflix account, which was linked to the stolen TV and Blu-ray, according to the sheriff's office. Using Netflix and IP address information, authorities traced the internet usage to Bobby Alexander of Mariposa, officials said.

President Barack Obama hosted a science fair at the White House on Monday. The president saw 35 projects from student teams from across the country who won various competitions, and one of those students is from the Bay Area. Ruchi Pandya is a senior at Lynbrook High in San Jose. Using tiny carbon nanofibers, Ruchi created a thumbnail-sized sensor that may one day save a lot of lives. “I can actually, with one drop of blood, tell you what a certain protein concentration in your bloodstream is. That’s an indicator for cardiac arrest,” Ruchi told KPIX 5 via Skype. Which...

The number of students graduating with STEM degrees already far exceeds the number of STEM jobs available but powerful interests in the business community are pushing Congress to allow more foreign skilled workers into the country. Congress is considering new immigration laws that would flood the U.S. with “guest workers” from the Middle East and Asia, a plan some are calling an open invitation for jihadists to walk right through America’s front door. Critics say lawmakers – including top Republican leaders – are playing with fire and could jeopardize national security with the proposals to double or even triple...

The world’s first fully digital radio transmitter has been developed by Cambridge Consultants, paving the way for 5G high-speed broadband for mobile devices. Unlike software-defined radio (SDR), the breakthrough – named Pizzicato – is not a mixture of analogue and digital components but is completely digital, which can enable new ways of using the radio spectrum intelligently. When transmitting data, only low frequency signals of 1GHz or lower propagate well over distance or through walls, so they are in great demand. Expanding to make use of frequencies of 10GHz and beyond will require techniques such as meshing and beamforming...

Before Hillary Clinton’s news conference yesterday, Jen Psaki, the spokesperson for the United States Department of State, stated that the White House could not immediately released the former Secretary of State’s emails because “it will take several months” to redact all the classified things she sent. Despite this, Ms. Clinton then stated in her press conference, “I did not email any classified material to anyone on my email. I’m certainly well aware of the classification requirements and did not send classified material.” Someone is not telling the truth. Either Ms. Psaki lied in order to prevent the immediate release of...

I’ve raised in prior posts (here and here) the issue of physical security of the clintonemail.com e-mal server, which is why were it was located and how it was set up matters. Last night, Mitch LaKind — who has experience setting up secure military e-mail servers — wrote me about the detailed issues surrounding Clinton’s approach. I’ll let him speak for himself (emphasis mine, though): As a former contractor to the Air Force, I personally managed the Microsoft Exchange servers that were installed at Thule Air Base. My experience with Microsoft Exchange goes back to 1997, when the earliest versions...

With YouTube to watch, Instagram pictures to take and Facebook, Snapchat and other social media platforms to explore, a generation of young Americans that used to turn to television for entertainment is finding its fix elsewhere. They are watching on-demand services, such as Netflix and Hulu and the BBC iPlayer but turning off “linear” TV, or tuning in at a set time on a set channel. This migration has been gradual but is starting to show up in the quarterly results of some of the world’s biggest media companies — and investors are beginning to notice.

The hunt for Earth-like planets around distant stars could soon become a lot easier thanks to a technique developed by researchers in Germany. In a paper published today, 18 February, in the New Journal of Physics, the team of researchers have successfully demonstrated how a solar telescope can be combined with a piece of technology that has already taken the physics world by storm—the laser frequency comb (LFC). It is expected the technique will allow a spectral analysis of distant stars with unprecedented accuracy, as well as advance research in other areas of astrophysics, such as detailed observations of the...
