Large Hadron restart delayed again -- you can relax until October

by Tim Stevens, posted Jun 22nd 2009 at 7:27AM

If you were enjoying these warmer months, taking time away from terrestrial black hole spotting due to the continued deactivation of CERN's Large Hadron Collider, feel free to extend those summer vacation plans a little bit. The particle crasher and supposed non-threat to life as we know it was previously set to restart in September after some damage put it on the inactive list many moons ago. Now CERN's Head of Communications, James Gillies, is saying that the restart is likely to be smashed back a few more weeks into October, meaning New Englanders might just get in one more leaf peeping season before all we know is mashed into an incomprehensibly small ball of matter from which nothing can escape -- not even Gundam robots.

Spintronics magic appears again, aims to vastly accelerate data storage and retrieval

by Darren Murph, posted Jun 7th 2009 at 5:21AM

As the list of "awesome things that won't ever happen" grows ever longer, we've got a brilliant team of French physicists who have seemingly concocted a method for storing and retrieving data on hard discs that's around 100,000 times faster than usual. Yes, 100,000x. The trick is based around spintronics, an almost mythical procedure that involves the use of lasers, magnetic sensors and mutant abilities to shuffle data around at a dizzying rate. This particular method, however, improves upon the comparatively sluggish attempts of the past, as it uses photons that "modify the state of the electrons' magnetization on the storage surface." In layman's terms, this all means that the HDD you buy in 2098 will probably operate significantly faster than the one you picked up during Circuit City's going-out-of-business sale. Got it? Good.

Preyro robot experiment could enable robots to better mimic animals, kill us all

by Darren Murph, posted Jun 1st 2009 at 6:42AM

It's kind of strange, really, how we can see just how near the end is, yet these so-called geniuses employed within the realm of academia are totally oblivious to their own evil deeds. Take cognitive science professor John Long, for instance, who is currently conducting a Preyro robot experiment in a Vassar College lab that intends to "allow robots to mimic animals far better than before." To him, he's just hoping to study evolutionary patterns in order to better understand how certain tweaks to things like fins and tails affect performance in the place we call reality. Though, there's a very real possibility that this research could accelerate the impending robot apocalypse by at least a score. Oh, what we'd give to be incognizant of the truth.

Corkscrew nanopropellers may one day deliver drugs internally

by Darren Murph, posted Jun 1st 2009 at 12:56AM

Clearly, vaccinations are so three years ago. As the race continues to find the best, most mobile internal transportation device for delivering drugs to remote places within the body, Peer Fischer of The Rowland Institute at Harvard University has teamed with colleague Ambarish Ghosh to concoct the wild creation you see to the right. The glass-derived nanopropeller was designed to move in a corkscrew motion in order to plow through syrupy, viscous liquids within the human frame. The device itself is fantastically small, measuring just 200 to 300 nanometers across at the head and 1 to 2 micrometers long. Fischer points out that each of these can be controlled with a striking amount of precision via an external magnetic field, though we don't get the impression that they'll be on to FDA testing in the near future. Ah well, at least our gra, er, great-grandchildren will be all taken care of.

Acoustic superlens could mask ships from sonar... in theory, anyway

by Darren Murph, posted May 31st 2009 at 9:32PM

Man, the mad scientists are really on a roll of late. First we hear that Li-ion cells are set to magically double in capacity, and now we're learning that a new form of invisibility cloak is totally gearing up for its Target debut. As the seemingly endless quest to bend light in such a way as to create a sheath of invisibility continues, the University of Illinois at Urbana-Champaign's Nicholas Fang has reportedly developed a metamaterial that acts as a type of acoustic superlens. In theory, at least, this approach would rely on phreaking with sound rather than light in order to intensely focus ultrasound waves; by doing so, one could hypothetically "hide ships from sonar." To be fair, this all sounds entirely more believable than hiding massive vessels from human sight, but we're still not taking our skeptic hat off until we see (er, don't see?) a little proof.

More scientific black magic promises to double Li-ion battery capacity

by Darren Murph, posted May 30th 2009 at 11:52PM

Go on and file this one away in the folder of "awesome things that could, but won't ever happen." As the brilliant minds around the world figure out how to solve vicious diseases, move motorcars with peanut oil and send engineers to fix a telescope in outer space, we still can't buy a pack of AA cells that last longer than a month or two in our favorite toy. Some call it a limit of physics, some deem it a conspiracy. Whatever the case, we've no doubt whatsoever that a new silicon-containing carbon material -- designed by Dow Corning Toray to double the capacity of existing Li-ion batteries -- won't ever have a real impact in our lives. Of course, it's not like any consumer would actually benefit from having a netbook battery good for 16 hours, nor would wedding photographers enjoy being able to shoot 1,000 indoor shots without cracking the battery door open on their SB-600. No -- that's just absurd. C'mon Dow, prove us wrong here.

Purdue researchers concoct new invisibility cloak, plan Walmart debut

by Darren Murph, posted May 22nd 2009 at 9:21AM

Hate to say it, but we're beyond the point of hope here. We just won't ever, ever see a real-deal invisibility cloak during our relatively brief stint on Earth. That said, researchers at Purdue University are doing their best to prove us wrong, recently developing a new approach to cloaking that is supposedly "simple to manufacture." Unlike traditional invisibility cloaks, which rely on exotic metamaterials that demand complex nanofabrication, this version utilizes a far simpler design based on a tapered optical waveguide. A report from the institution asserts that the team was able to "cloak an area 100 times larger than the wavelengths of light shined by a laser into the device," but for obvious reasons, it's impossible to actually show us it happened. Regardless, for the sake of the kiddos above, we're hoping this stuff gets commercialized, and soon.

DARPA working on "Silent Talk" telepathic communication for soldiers

by Laura June, posted May 14th 2009 at 5:41PM

We're no strangers to crazy DARPA projects around here, but this one especially strikes our fantastic fancy. The agency's researchers are currently undertaking a project -- called Silent Talk -- to "allow user-to-user communication on the battlefield without the use of vocalized speech through analysis of neural signals." That's right: they're talking about telepathy. Using an EEG to read brain waves, DARPA is going to attempt to analyze "pre-speech" thoughts, then transmit them to another person. They first plan to map people's EEG patterns to his / her individual words, then see if those patterns are common to all people. If they are, then the team will move on to developing a way to transmitting those patterns to another person. Dream big, that's what we always say!

Nanocrystal breakthrough promises more versatile lasers, world peace

by Darren Murph, posted May 11th 2009 at 8:02AM

For the longest while, scientists have been flummoxed by the incessant coruscating emitted by individual molecules; no matter their methods, they could never quite seem to overcome a troubling optical quirk known sensibly as "blinking." Thanks to a brilliant crew at the University of Rochester, however, we now understand the basic physics behind the phenomenon, and together with a team from Eastman Kodak, a nanocrystal has been created that can constantly emit light. In theory, the discovery could lead to "dramatically less expensive and more versatile lasers, brighter LED lighting, and biological markers that track how a drug interacts with a cell at a level never before possible." Indeed, one could envision that future displays could be crafted by painting a grid of differently sized nanocrystals onto a flat surface, making even OLED TVs look chubby in comparison. Now, if only we had a good feeling that such a device was destined for a CES in our lifetime...

Quantum cryptography: now ready for space travel

by Darren Murph, posted May 4th 2009 at 7:37AM

It's been awhile since we've heard of any major advancements in the world of quantum cryptography, but at long last the silence is being broken by a squad of jubilant Austrian physicists. As the story goes, a team from Austria's Institute for Quantum Optics and Quantum Information (IQOQI) managed to send "entangled photons" 90 miles between the Spanish islands of Las Palmas and the Balearics. Calling the ephemeral test successful, the crew has boldly asserted that it's now feasible to send "this kind of unbreakable encrypted communication through space using satellites." Funny -- last we remember, quantum cryptography still had a few kinks to work through here beneath the stratosphere.

Researchers develop technique to unscramble light for a much sharper picture

by Ross Miller, posted May 3rd 2009 at 7:42AM

Trying to circumvent the need to choose between getting a wide-angle shot and zooming in for details, a team of researchers at Princeton led by electric engineer Jason Fleischer have developed a new method to get the best of both worlds, by passing the light through a "nonlinear crystal" that would normally distorts the picture. A computer algorithm then pieces together the data and, as they claim, produces a wide-view image that also manages to capture the finer points otherwise missing when using conventional techniques. The goal is to build "super-resolution" microscopes for better medical diagnostics, but the group also sees uses in the fields of data encryption and lithography / microchip production. Is it too much to ask that our next Canon or Nikon have this a standard feature?

Inventors develop transistor to change color of any surface, your face notwithstanding

by Darren Murph, posted Apr 27th 2009 at 4:13AM

Color shifting has been a pipe dream for about as long as alchemists have claimed their studies to be legitimate, but now a brilliant team from the New University of Lisbon can finally say a breakthrough has been found. Essentially, these inventors have conjured up a transistor that changes the color of practically any surface (paper, glass, plastics, ceramics and metals, just to name a few). For what it's worth, this same team already has quite a bit of display cred, as it has developed technology currently used within Samsung panels. With the help of a few good men and woman at the University of Texas at Austin, the team was able to register for a patent right here in the US, and with any luck, they'll be giving OLEDs and e-paper a run for their money before we can snap our fingers twice and run around the block. Check a video (narrated in Portuguese) after the break.

[Thanks, Nelson]

New cooling material keeps heat down in densely packed electronics

by Darren Murph, posted Apr 9th 2009 at 3:17AM

Oh sure, liquid cooling rigs are all the rage, but they aren't too useful within minuscule things like netbooks, MIDs and pocket projectors. The always churning minds over at Fraunhofer-Gesellschaft are already on the issue, recently conjuring up a new material designed to "efficiently dissipate heat even in devices with densely packed components and that can give increasingly miniaturized electronics a longer life." Researchers at the entity's Institute for Manufacturing Engineering and Applied Materials Research have teamed with gurus from Siemens and Plansee to create the substance as part of the EU project "ExtreMat." Unfortunately, details beyond that are few and far between, but given that demonstrations have reportedly "already been produced," we'd say it's well on its way to infiltrating things far smaller than your mind can grasp.

Artificial Intelligence solves boring science experiments, makes interns obsolete

by Joseph L. Flatley, posted Apr 3rd 2009 at 10:47AM

Researchers at Aberystwyth University in Wales have developed a robot that is being heralded as the first machine to have discovered new scientific knowledge independently of a human operator. Named Adam, the device has already identified the role of several genes in yeast cells, and has the ability to plan further experiments to test its own hypotheses. Ross King, from the university's computer science department, remarked that the robot is meant to take care of the tedious aspects of the scientific method, freeing up human scientists for "more advanced experiments." Across the pond at Cornell, researchers have developed a computer that can find established laws in the natural world -- without any prior scientific knowledge. According to PhysOrg, they've tested the AI on "simple mechanical systems" and plan on applying it to more complex problems in areas such as biology to cosmology where there are mountains of data to be poured through. It sure is nice to hear about robots doing something helpful for a change.

Light-activated lock could revolutionize drug delivery

by Darren Murph, posted Apr 3rd 2009 at 1:57AM

The Gators may not be in the Final Four this year, but the brainiacs on campus are still toiling away, regardless. Researchers at the institution (that'd be the University of Florida) have just stumbled onto a remarkable discovery that could eventually "starve cancer tumors and prevent side effects from a wide range of drugs." The magic find? A "lock-like molecule" that clasps or unclasps based on exposure to light. Sure, we've seen our fair share of newfangled drug delivery tools, but none that have been this noninvasive or simple to activate. In tests, gurus found that they could use visible or ultraviolet light to open or close a clasp, letting blood flow or creating a clot; in theory, this could one day be used to "prevent the formation of tiny blood vessels that feed tumors." Everything about this sounds just fantastic on the surface, but seriously, can you imagine how dead we'd be if the robots ever got ahold of this?
