‘Sonar Vision’ system touted by researchers to help the blind hear what they can’t see

Sonar Vision

Scientists from the Hebrew University of Jerusalem have developed a prototype system that could one day aid the congenitally blind by converting video into auditory cues. The “Sonar Vision” works in a similar way to a bat’s echolocation system, but instead of chirping, uses a video camera embedded in a pair of glasses. A laptop or smartphone then converts the images into sound, which is transmitted to a headset. After 70 hours or so of training, that allowed users to identify objects like faces or houses, position objects in space and even identify individual letters. Surprisingly, researchers also found that after only several hours using the device, regions of the cerebral cortex dedicated to sight became activated for the first time in the congenitally sightless. That could possibly let doctors “wake up” regions of the brain never before used, according to the team, “even after a lifetime of blindness.”

This Generator Steals Energy From Passing Trains

It’s estimated that in the US alone there’s over 140,000 miles of train tracks criss-crossing the country. So a team of researchers from New York’s Stony Brook University have developed a simple railside generator that’s able to convert the vibrations from a passing train into usable electricity. More »

Promising to turn even the poorest of doodlers into artificial Rembrandts, researchers at Keio University have developed a desk that will automatically guide the tip of a pen to draw straight lines or perfectly round circles. It can even guide an artists’ hand through a pre-determined illustration, making the technology sound like a forger’s dream come true. More »

Verizon lauded by Consumer Reports: Only LTE earns AT&T approval

Verizon’s cellphone service has come out top of the pack for major US carriers, with sterling 4G performance the only thing to rescue AT&T from poor ratings across the board. Based on a survey of more than 63,000 subscribers by Consumer Reports, the feedback praised Verizon for its voice and data quality, the knowledge of staff, and how promptly issues were resolved.

In contrast, AT&T, T-Mobile, and Sprint were all given “middling to low marks” in those categories, with voice and text service judged to be particularly disappointing.

However, while Verizon may have got to LTE first, it isn’t deemed the best 4G offering of all the networks. “[AT&T] users reported the fewest problems with that higher-speed service, which most new smart phones now use” Consumer Reports concludes.

It’s prepaid service which gets the biggest nod, however, with Consumer Reports recommending several no-frills and/or regional providers for the individual or family that wants the most for their dollar. US Cellular takes the top recommendation, with Credo Mobile in second place; if you’re not in the coverage of either, Verizon is in third place.

In fact, the organization found, the majority of those who jumped from contract to prepaid made a monthly saving. Two-thirds saved more than $20 per month, helping offset the higher upfront cost of the device.

Astronomers discover the most massive black hole ever

Astronomers have announced that they have discovered the most massive black hole ever found. The gigantic and massive black hole is in a small galaxy that is about 250 million light years from Earth. The astronomers estimate that the supermassive black hole has a mass equivalent to 17 billion suns.

The massive black hole is located inside the galaxy NGC 1277 found in the constellation Perseus. The supermassive black hole makes up 14% of the host galaxy’s mass. According to astronomers, the typical blackhole makes up only 0.1% of the mass of its host galaxy.

Scientist Carl Gebhardt from the University of Texas at Austin said, “this could be the first object in a new class of galaxy-blackhole systems.” The astronomers say that the supermassive blackhole is about 11 times as wide as the orbit of Neptune around the sun in our solar system. Interestingly, the incredible mass of the black hole was so far out of the range of normal that the team of scientists who discovered it took an additional year to verify their findings before submitting the research paper for publication.

The next closest competitor for size comes from galaxy NGC 4486B. That galaxy has a blackhole that makes up 11% of its central bulge mass. The research paper published by the astronomers who discovered the massive black hole in NGC 1277 can be found in the latest issue of the journal Nature, which is available today.

South Korean rocket launch called off during countdown

South Korean officials were set to launch their first rocket into space today, but were forced to call off the launch with only minutes to spare. The launch was South Korea’s third attempt to shoot a rocket into orbit and this was the second failed launch for this particular project. The launch was called off due to a glitch in the rocket propulsion system.

In October, the rocket launch was also postponed due to a glitch in the booster engines from Russia. Reports indicate that the rocket launch scheduled for today was called off just minutes before the scheduled liftoff. South Korean officials say that they are currently investigating what caused the glitch in the propulsion system.

While South Korea maintains that its rocket tests are part of its plan to be able to put satellites in orbit itself without having to rely on other countries, other powers in the region believe that the tests are a way for South Korea to work on its ballistic missile program. North Korea has been particularly vocal about South Korea’s rocket program.

North Korea maintains that is being unjustly singled out for UN sanctions for launching long-range rockets as part of its own space program with the goal of putting its own satellites in orbit. The glitch that halted the South Korean launch today is reported to be an error in the thrust vector control in the upper second stage of the rocket. That particular system guides the propulsion of the vehicle.

NPD: U.S. Windows Device Sales Down 21% On Last Year; Windows 8 Tablet Sales “Almost Non-Existent”

ASUS_EeePadTransformer_4.jpg-88df512f8e5aeab3

Microsoft earlier this week made a point of noting that there have been 40 million downloads of Windows 8 since it launched a month ago, putting it ahead of where Windows 7 was at the same point in its sales cycle. But according to figures out today from NPD, in the midst of an overall slowdown in PC sales, this is not translating into robust hardware sales in the influential U.S. market.

U.S. sales of Windows devices in the last month are down by 21% compared to the same period a year ago, with Windows-powered notebooks — generally in decline since the rise of tablets and smartphones — down by 24%. Desktop devices were down, too, but less, at 9%.

It gets worse. Microsoft has make a big bet on the touchscreen and tablets with Windows 8, but so far, NPD’s Stephen Baker says that Windows 8 tablet sales “have been almost non-existent.” Unit sales, he says, have been less than 1% of all Windows 8 device sales to date. The caveat is that NPD’s numbers do not include sales of Microsot’s own tablet, the Surface. (We are contacting Baker at NPD to see if he can give more detail on how those are selling and why they have been left out.)

So do these numbers indicate that — despite the record-breaking sales we’ve seen so far for online shopping this holiday season, which often gives an annual boost to the consumer electronics industry — Microsoft has a turkey on its hands in the form of Windows 8? Not exactly, says NPD. The problems could be just as attributable to a sluggish market at this point.

“After just four weeks on the market, it’s still early to place blame on Windows 8 for the ongoing weakness in the PC market,” writes Stephen Baker, vice president of industry analysis at NPD. “We still have the whole holiday selling season ahead of us, but clearly Windows 8 did not prove to be the impetus for a sales turnaround some had hoped for.”

There are still devices being sold with earlier versions of Windows, and NPD says that since launch Windows 8 hasn’t been performing as well against legacy equipment, compared to the same period in the Windows 7 sales cycle. It says 58% of Windows devices sold are loaded with Windows 8, versu 83% powered by Windows 7 one month after its launch.

“The bad Back-to-School period left a lot of inventory in the channel,” Baker explains.

Silver lining: hybrid devices — notebooks with touchscreens, such as the Asus Transformer, pictured — seemed to be doing alright. Yes, they accounted for just 6% of notebook sales, but with an average price of $867 (compared to $433 across all Windows devices) they show that there is at least some appetite for premium products, an area where Windows OEMs traditionally compete against Apple.


Scientists Claim Five-Year Study Has Yielded DNA Evidence of Bigfoot

If you ever watched the 80s flick Harry and the Hendersons, you may wondered if Bigfoot could actually exist. I can’t say one way or another if the mythical Sasquatch is a living creature or nothing more than a figment of the imagination. A group of scientists from claim to have concluded a five-year DNA study that is under peer review and confirmed the existence of Bigfoot.

harry hendersons

According to the scientists, they have been able to sequence 20 whole mitochondrial genomes and have used next-generation sequencing to obtain three whole nuclear genomes from samples claimed to be from a Sasquatch. The scientists say that DNA evidence suggests that Bigfoot is a human relative.

The scientists claim that the creature known as Bigfoot came to be approximately 15,000 years ago as a hybrid crossbreed of modern Homo sapiens and an unknown primate species. The scientists state that data indicates the Sasquatch was the result of males from an unknown hominin species crossing with female Homo sapiens.

Curiosity’s whole Mars mission is “history books” worthy clarifies NASA

NASA‘s teased data “for the history books” from the Curiosity Mars rover has all been a huge misunderstanding, the space agency now says, with the reference apparently encompassing the mission as a whole – not a specific finding. Anticipation was built earlier this month when principal investigator John Grotzinger told NPR that “this data is gonna be one for the history books” and that “it’s looking really good”; his comments were interpreted as specific to a set of soil sample results Curiosity’s onboard labs had just beamed back to Earth, but NASA says it was all a case of confusion.

In fact, Grotzinger’s statement had been intended to encompass the Curiosity mission as a whole, NASA clarified to Mashable, not to hint that the sample had contained evidence of organic compounds. Adding to the mix-up was the fact that the project lead voiced his enthusiasm just after discussing the first set of Sample Analysis at Mars (SAM) results had come in, but refused to detail them as they still needed to be checked over.

NASA tweeted out an attempt to calm expectations from the official Curiosity account, but the story had already caught the imagination and – following the identification of an ancient seabed – an organic discovery seemed all too possible.

“What did I discover on Mars? That rumors spread fast online. My team considers this whole mission “one for the history books”” CuriosityRover Twitter account, November 12, 2012

According to Veronica McGregor, NASA’s news and social media manager, the NPR team simply happened to be around at the right time to see some very excited scientists at work. “The short story is NPR was there when the first soil results were hitting the ground and the team was ecstatic to see data” she told Slate.

“Could they analyze that data on the fly and give an accurate result?” McGregor continued. “No. In fact, they’ve spent a good part of two weeks sorting through the data in order to reach conclusions based on solid science.”

The results of that solid science will be shared at a press conference on December 3 at the American Geophysical Union meeting, an event that has been on the calendar since before Curiosity reached the red planet. And, while it’s possible that NASA’s Jet Propulsion Laboratory could have some groundbreaking news from Curiosity, with a two year mission planned, we may have to wait a little longer to see Mars give up some of its secrets.

Nuclear engine could power future deep space exploration

The distances a spacecraft has to travel for deep space exploration are enormous. The engines used to power spacecraft currently simply aren’t up to the task of exploring deep space or even our own solar system in a reasonable timeframe. Another problem with spacecraft currently is that they rely mostly on solar power to operate sensors and scientific equipment.

The further spacecraft get from the sun, the less power they’re able to harvest and the less efficient and functional they become. Researchers are currently testing a small prototype engine that could be the future of deep space exploration. The prototype engine is based on a Stirling engine that was invented in the 19th century.

A Stirling engine uses hot pressurized gas to push a piston. The engine that the scientists envision would use a 50-pound nuclear uranium battery to generate heat that would then be carried to 8 Stirling engines able to produce about 500 W of power. Scientists at NASA’s Glenn Research Center and Los Alamos National Laboratory are currently testing a smaller prototype of the proposed design.

The prototype uses a small nuclear source and a single Stirling engine that is able to produce 24 W of power. According to the scientists, most deep space probes need 600 to 700 W of power to operate. This project is also notable because it is the first test of a nuclear reactor system for powering spacecraft the US has conducted since 1965. The scientists say that nuclear power sources for deep space probes are important because once a spacecraft passes Mars, sunlight is so weak that it would require solar panels about the size of a football field to produce enough power to transmit data back to Earth.
