80FFTs Per Second To Detect Whistles (and Switch On Lights)

Posted by on May 9, 2013 No comments

New submitter Mathieu Stephan writes “Hello everyone! Some people told me that my latest project might interest you. I’m not sure you publish this kind of projects, but here it goes. Basically, it is a small platform that recognizes whistles in order to switch on/off appliances. It will be obviously more useful for lighting applications: just walk in a room, whistle, and everything comes on. The project is open hardware, and all the details are published on my website.” The linked video is worth watching for the hidden-camera footage alone: it would be hard to not keep playing with this sensor.

Laser Intended For Mars Used To Detect “Honey Laundering”

Posted by on February 18, 2013 No comments

A laser tool funded by the European Space Agency to measure carbon on Mars is now being used to help detect fake honey. By burning a few milligrams of honey the laser isotope ratio-meter can help determine its composition and origin. From the article: “According to a Food Safety News investigation, more than a third of honey consumed in the U.S. has been smuggled from China and may be tainted with illegal antibiotics and heavy metals. To make matters worse, some honey brokers create counterfeit honey using a small amount of real honey, bulked up with sugar, malt sweeteners, corn or rice syrup, jaggery (a type of unrefined sugar) and other additives—known as honey laundering. This honey is often mislabeled and sold on as legitimate, unadulterated honey in places such as Europe and the U.S..”

Astronomers Detect and ‘Weigh’ Very Young Solar System

Posted by on December 9, 2012 No comments

ogre7299 writes “Astronomers have found direct evidence of a forming proto-solar system and ‘weighed’ the forming star for the first time The results were reported in Nature (abstract) and the pre-print is available at the arXiv. ‘The star, called L1527 IRS, is only one-fifth the mass of the sun, and is expected to keep growing as the swirling disk of matter surrounding it falls into its surface. Astronomers estimated the star formed around the same time that Neanderthals evolved on Earth: just 300,000 years ago. … Generally, a star forms from a cloud of gas that collapses into itself. Material streams inward from the cloud and forms a protostar in the center of a disk of gas and dust. Over millions of years, material falls on the protostar and releases quite a bit of energy. In L1527, 90 percent of its energy comes from material landing on the surface of the protostar. The remaining 10 percent comes from the star itself.’ Measurements for the research came from the Submillimeter Array and the Combined Array for Research in Millimeter-wave Astronomy.”

Can a Blood Test Detect Autism Early?

Posted by on October 8, 2012 No comments

A company has developed a simple blood test to identify most cases of autism—but determining if it really works is not so simple.

A company called SynapDx is hoping that a simple blood test will be able to identify most cases of autism in children much faster than current evaluations. At the Consumer Genetics Conference in Boston last week, SynapDx founder and CEO Stanley Lapidus said the company would soon begin evaluating the ability of its diagnostic test, which examines gene activity, to identify children with the disorder. While such a test would be of great value if successful, the concept is “risky,” says a company scientific adviser, because it’s not yet known whether there is a molecular signal for autism.

Ask Slashdot: What’s a Good Tool To Detect Corrupted Files?

Posted by on May 7, 2012 No comments



Volanin writes “Currently I use a triple boot system on my Macbook, including MacOS Lion, Windows 7, and Ubuntu Precise (on which I spend the great majority of my time). To share files between these systems, I have created a huge HFS+ home partition (the MacOS native format, which can also be read in Linux, and in Windows with Paragon HFS). But last week, while working on Ubuntu, my battery ran out and the computer suddenly powered off. When I powered it on again, the filesystem integrity was OK (after a scandisk by MacOS), but a lot of my files’ contents were silently corrupted (and my last backup was from August…). Mostly, these files are JPGs, MP3s, and MPG/MOV videos, with a few PDFs scattered around. I want to get rid of the corrupted files, since they waste space uselessly, but the only way I have to check for corruption is opening them up one by one. Is there a good set of tools to verify the integrity by filetype, so I can detect (and delete) my bad files?”

Physicists Detect Elusive Orbiton By “Splitting” Electron

Posted by on April 19, 2012 No comments



ananyo writes “Condensed-matter physicists have managed to detect the third constituent of an electron — its ‘orbiton’. Isolated electrons cannot be split into smaller components, earning them the designation of a fundamental particle. But in the 1980s, physicists predicted that electrons in a one-dimensional chain of atoms could be split into three quasiparticles: a ‘holon’ carrying the electron’s charge, a ‘spinon’ carrying its spin and an ‘orbiton’ carrying its orbital location. In 1996, physicists split an electron into a holon and spinon. Now, van den Brink and his colleagues have broken an electron into an orbiton and a spinon (abstract). Orbitons could also aid the quest to build a quantum computer — one stumbling block has been that quantum effects are typically destroyed before calculations can be performed. But as orbital transitions are extremely fast, encoding information in orbitons could be one way to overcome that hurdle.”

MIT’s laser-powered camera can detect objects hidden around corners (video)

Posted by on March 21, 2012 No comments

One of the most thrilling things about human existence is that you never know what’s lurking around the corner. It could be a newborn baby, a sweet job, a delicious churro — doesn’t really matter, because it’s a surprise, and surprises are fun and surprising. Just don’t tell that to the doldrum dwellers over at MIT, because apparently, they don’t agree. The same team that created a camera with light-speed shutter rates has now expanded upon their project, with a camera capable of seeing around corners. Literally. To do this, the system uses a so-called femtosecond laser to send out extremely short light pulses — so short, in fact, that their entire lifespan is measured in quadrillionths of a second. To capture an object lurking around a corner, the device aims its laser at a nearby wall, thereby allowing the light to bounce around the room before eventually landing on the concealed object. Once it hits the jackpot, the light will reflect back onto the wall, and eventually return to a detector, which can gauge the exact location of the object based on the distance the laser traveled. This happens over and over again at different angles, meaning that the system will ultimately be able to get a general idea of the hidden room’s layout. Researchers hope that their system will eventually be used in emergency rescue situations, or to help drivers see what’s around the bend, though there’s no telling when any of that could actually happen. For a diagrammatic rundown, check out the video after the break.

Wi-Fi Cards Can Now Detect Microwave Ovens

Posted by on September 24, 2011 No comments

An anonymous reader writes “Researchers at UW Madison have used regular WiFi cards to detect non-WiFi interference sources like microwave ovens, Bluetooth devices, cordless phones, Xbox controllers and video cameras. They call their software Airshark. Current products like Wispy, Spectrum Expert are expensive and need extra hardware, whereas Airshark is a software-only solution that can directly work on the Wi-Fi cards on your laptops and APs. This also paves way several interesting applications. For example, your WiFi network will not be affected anymore just because your neighbor switched on a microwave oven or a cordless phone — the newer WiFi APs will be able to switch the channels and adapt to the interference accordingly.”
