MacGyver and Maxwell Smart had a plethora of tricks up their sleeves (or shoes, as it were), but they never had this. One Paul Kelly and colleagues at Loughborough University have discovered that a disulfur dinitride polymer can not only turn exposed fingerprints brown as it creates a reaction with the nearly undetectable residues, but it can also lift text from departed letters. In an odd twist of fate, it was found that traces of ink jet printer ink can actually initiate the polymer just like print residue can, and the detection limit is so low that details from a letter that was once within an envelope can be seen after adequate exposure to the chemical. And you thought snail-mailing those interoffice love letters was a safe bet.

Seriously, is there anything carbon nanotubes can't do? We've got shock absorbers, flexible displays, atypically small eating utensils and now, film-like speakers. For times when NXT flat drivers simply aren't thin enough, a team of Chinese researchers have reportedly found a way to create sound from a thin sheet of carbon nanotubes. The film, which could be stretched and placed on PMPs, HDTVs or even clothing, can generate sound when "zapped with a varying electric current." Great, the perfect recipe for a new wave of Milli Vanilli copycats. A video of the tech can be seen after the jump.

Far from being the first artificial heart we've seen, the latest iteration unveiled by a team of French scientists is easily the most sophisticated. Built from technology used in satellites and airplanes, the prototype heart is said to "beat almost exactly like the real thing using electronic sensors to regulate heart rate and blood flow." Reportedly, the device boasts "the same tiny sensors that measure air pressure and altitude in an airplane or satellite," enabling it to theoretically react in an instant if the patient suddenly needs more or less blood. Thus far, the heart has only been tested in animals, and now gurus behind it are hoping to net approval from authorities in order to forge ahead with clinical trials. Of course, a "lifelike" heart made from polymer and pig tissue won't come cheap, with initial pricing estimates putting it just south of 200 grand. Or, just enough to give you a heart attack.

Last we heard, IBM was busy extending optical lithography down to 30-nanometers in order to keep Moore's Law intact, and some two years later, the process is still being honed by engineers at the University of California, Berkeley. Reportedly, gurus there with IQs far greater than ours have developed a new patterning technique (plasmonic nanolithography) that could make "current microprocessors more than 10 times smaller, but far more powerful." Additionally, professor Xiang Zhang asserts that this same technology could eventually "lead to ultra-high density disks that could hold 10 to 100 times more data than disks today." The secret to the madness is a flying plasmonic head, which is compared to the arm and stylus of an LP turntable; the setup enables researchers to "create line patterns only 80-nanometers wide at speeds up to 12-meters per second, with the potential for higher resolution detail in the near future." In layman's terms? That CPU you purchased last month will, in fact, be old hat in due time.

Not to get too nano-technical on you this Saturday afternoon, but you're probably going to want to be briefed on these newfangled macroscopic aggregates commonly referred to as buckypapers. The devices, which are reportedly involved in a long-term undercover relationship with those buckyballs you discussed in 10th grade chemistry class, are ridiculously tough (albeit lightweight) sheets of matter made from intertwined carbon nanotubes. Put simply, these composites could see uses in making more efficient heat sinks, lighter background illumination material for displays and (at least in theory) transportation of the future. For now, buckypapers are being made exclusively in university laboratories, but Florida State is already in the process of spinning out a firm to make them commercially. Do we see the makings of a new and improved Project Grizzly suit? Our signs are pointing to yes.

Contrary to popular belief, the world as we know it didn't implode after the Large Hadron Collider was flipped on. Sure -- someone, somewhere is growing a ninth arm and trying desperately to land a cameo on Fringe, but the planet at large is still humming along just fine. Now, the world's most ginormous computing grid (the Worldwide LHC Computing Grid, or WLCG) has gone live, and the gurus behind it are celebrating the beginning of its momentous data challenge: to analyze and manage over 15 million gigabytes of data each year. The Grid combines the IT power of over 140 computer centers, 100,000 processors and the collaborative efforts of 33 countries. Unfortunately, there's no word on when the official WLCG-based Call of Duty 4 server will be green-lit for action, but we hear it's pretty high on the priorities list.

Given how large the green bandwagon has become, it's no real shock to see an energy-saving concept from the 1930s being exhumed and investigated further. Scientists at Oxford University have begun to take a closer look at an early invention from the great Albert Einstein in order to hopefully create refrigerators (and appliances in general) that could be used completely without electricity. Back in the day, Sir Albert created a mechanism that had no moving parts and used only pressurized gases to keep things chilly. Once compressors became more efficient in the 50s, however, the idea was tossed aside. Now, the idea obviously has greater appeal, and if things keep humming along nicely, a completed prototype should be erected by the year's end.

We'll warn you in advance, this is only for those who dig the weird, all things Stephen Hawking or clock-making in general. This £1 million ($1.83 million) timepiece took seven years to completely construct, and the initiative was led by inventor John Taylor who designed it in tribute to John Harrison (only the world's greatest clockmaker, it's said). The bizarre Corpus Clock visually explains that it relies on grasshopper escapement to function, and to let you know that time can never be regained once lost, that beast on top actually gobbles down time every 60th second. Oh, and every hour, on the hour, the sound of a "chain dropping into a wooden coffin" is played to really pound home the "time is a destroyer" concept. Thanks for the reminder, Dr. Grim.

Really people, enough is enough. Death threats? Seriously? According to a fresh report from the Telegraph, gurus working on the mysterious Large Hadron Collider are receiving all sorts of strange messages, e-mails and faxes as the go-live date (this Wednesday, supposedly) draws ever closer. For those curious about why some folks are up in arms over this thing, we'll simply point you to this very informational rap video; for those opposed to nerdy hip-hop, let's just say its primary goal is to "seek out new particles including the long-awaited Higgs boson responsible for making things weigh what they do and the possible source of gravity called dark matter." Somehow or another, the paranoid among us think that carrying out those tasks will rip the world wide open or leave you stuck in 1990 with nothing in your CD player but Ice Ice Baby. Okay, so maybe that last scenario is worth getting worked up about.

Gore-Tex is fine and dandy, but the real argonauts out there know it still buckles under the most extreme conditions. Now, however, adventurists that happen upon a ridiculous amount of water could soon ford rivers (à la Oregon Trail, of course) without worrying about soggy socks. The technology, dubbed ion-mask, was originally crafted to "ensure soldiers' clothing remained impermeable to chemical weapons," but now shoe maker Hi-Tec has inked a deal that will being the solution to a smattering of its kicks. Reportedly, ion-mask can outperform "commercial waterproof fabrics such as Gore-Tex by more than a factor of 100," and in testing, it maintained its breathability / waterproof abilities even after 100,000 flexes. No word on when full suits will be doused in this stuff, but hopefully you'll be able to wear the same outfit to the office and the jungle here shortly.

It's hard to say when we, the consumers, will actually see any real benefit from the latest noteworthy discovery from Northeastern University, but we can only imagine that Srinivas Sridhar and team aren't wasting any time moving things forward. Said crew has recently created a "new microlens that focuses infrared light at telecommunication frequencies," and if you're looking for specifics, it can focus an infrared beam to a spot just 12-micrometers away from the surface. The science behind the discovery is probably only digestible by those that understand rocket science, but the long of short of it is this: the "research shows that it is possible to create smaller, ultra-compact infrared optical components that can be integrated into existing semiconductor technologies while not sacrificing image quality." Now that's something even the layman can appreciate.

On a number of occasions, we've seen reports suggesting that pacemakers could be sent signals which could instruct them to do all sorts of unwanted things, including shut off completely. Thankfully, the University of Washington's Dr. Tamara Denning has heeded the warnings and created a possible solution. The so-called cloaking device would enable pacemakers to "resist any instructions that come from anyone other than the doctor," though it has yet to be put to the test. in the real world Now, making sure your doc has passed a sufficient amount of background checks is another matter entirely.

Just under two years ago, researchers at Boeing-Spectrolab managed to achieve 40.7% solar cell efficiency. Two years later, scientists at the US Department of Energy's National Renewable Energy Laboratory have demonstrated their nerve by trumpeting an all new world record... one that's 0.1% points better than the last. Yes, your new record now sits at 40.8% -- tremendous progress, wouldn't you say? Looking outside of the numbers, you'll find that these cells differ "significantly" from the prior record holders, which enable them to be thinner, lighter, cheaper and altogether swanker. That's it for now folks -- come back in a couple years, we hear 40.9% is just around the bend.

Been having a tough time figuring out just what CERN's Large Hadron Collider does? Worried that it will create a Möbius strip (a rip in the fabric of space where time becomes a loop)? Just love to jam? Watch this CERN-sponsored rap after the break, and have your universe totally destroyed. Er, but not for real.

Here's your afternoon dose of cuteness, ready or not. David McGoran's Heart Robot has made its way into London's Science Museum, and for good reason. This intelligent robot not only possesses a face with moving eyes and an external heart that blinks depending on what's happening, but it actually encourages people to hug and cuddle it like a real human. Seen as being "among the first robots to signify a new era of emotional machines used for medical treatment and enjoyment," this creature could one day become a mainstay in nursing homes where the elderly could interact with it and hopefully benefit in some metaphysical manner. Check out the read link for a video oozing with adorableness.
