Optogenetics hold the key to future brain disease cures, still creep us out

by Vladislav Savov posted Oct 21st 2009 at 10:26AM

Those mad neuroscientists, they'll never learn, but maybe in the end we'll all be better off for it. Wired has put together an extremely intriguing write-up of the short history of optogenetics -- featuring a German pond scum researcher, a Nobel Prize winner, and rat brains controlled by beams of light. Optogenetics is a relatively new technique for communicating with the brain, which involves the implantation of particular light-sensitive genes into animals with the purpose of repairing neurological ailments through light therapy (no, not that kind). By hooking up fiber-optic cables to the affected area of the brain, researchers have been able to completely restore movement in mice with Parkinson's disease and their current efforts revolve around developing a less invasive method that doesn't go deeper than the outer surface of the brain. Most revolutionary of all, perhaps, is the eventual possibility for two-way traffic (i.e. a machine being able to both send and receive information from the brain), which brings all those cyborg dreams of ours closer to becoming a reality than ever before. Hit up the read link for the full dish.

Nobel Prize in Physics shared by CCD inventors, fiber optics pioneer

by Donald Melanson posted Oct 6th 2009 at 2:08PM

It's not every year that the Nobel Prize in Physics falls within our scope of coverage, but this year turned out to a big exception, as the Royal Swedish Academy of Sciences has deemed it fit to recognize two breakthroughs in the fiber optics and digital photography. The first of those (and half of the $1.4 million prize) goes to Charles K. Kao, whose work in the mid-60s getting light to travel long distances through glass strands made the fiber optic cables we have today possible. The second half of the prize is divided between Canadian Willard S. Boyle and American George E. Smith, who both worked at Bell Labs in Murray Hill, New Jersey, and invented the so-called charge-coupled device semiconductor, better known to anyone that has ever looked at a digital camera spec list as a CCD.

Bell Labs uses 155 lasers to beam ridiculous amounts of data over 7,000 kilometers

by Tim Stevens posted Oct 1st 2009 at 11:09AM

Let's say you have a monumental collection of data at your place. Like, say, everything ever posted to the Pirate Bay. And let's say the Feds are beating down your door and you need to dump that data to a secure off-site storage facility right now. Who do you call? A lawyer, of course, because currently there's no practical way to do such a thing. But, in the not too distant future you might call up Bell Labs, a company whose scientists managed a monumental 100 Petabits per second per kilometer transmission rate using 155 lasers at different optical frequencies. If you take distance out of the equation you're looking at 15.5 Terabits per second, more than ten times faster than the last laser transmission test we reported on. Naturally, this was conducted in conditions that don't quite equate to the real world at large, and it's going to be a long time before we have fiber pipes like that beaming data into our homes. So, hands up chum, and make that one call count.

Australia's A$43 billion broadband project: up to 100Mbps in 90% of homes and businesses

by Ross Miller posted Apr 7th 2009 at 3:04AM

In what he's calling "the single biggest infrastructure decision" in the country's history," Australia Prime Minister Kevin Rudd's announced an A$43 billion (US $30.6 billion) project to create a nationwide high speed broadband network. The goal's to get 90 percent of homes and business up to 100Mbps speeds with fiber optic connection, with a less impressive 12Mbps wireless / satellite for the rest. Up to 49 percent of the funds will be from the private sector; the government will initially invest A$4.7b, while A$20b will come from a national infrastructure fund and the sale of bonds. The venture's expected to take seven to eight years, and Rudd said the government intends to sell off its stake after five years. Sure, it's not 1Gbps by 2012, but hey, they might end up beating us at the "nationwide broadband" game.

Intel's opto-electronic 'breakthrough' could save this doomed Internet (or not)

by Joseph L. Flatley posted Dec 9th 2008 at 1:03PM

It seems like every tale of impending bandwidth "disaster" is soon countered by a new bandwidth "breakthrough." In this case, researchers at Intel have been testing a silicon-based Avalanche Photo Detector (APD) (as opposed to the traditional, and rather expensive, indium phosphide), and so far results have been quite promising. On one key metric, something called the "gain-bandwidth product," the APD achieved speeds of 340GHz, or as the gang at Intel puts it, the "best result ever." It is hoped that this product could significantly lower the price of 40Gbit/s (and faster) optical links and find a home in areas like quantum cryptography, biochips and eventually chip-to-chip and on-chip interconnects. And most importantly, this could be huge for our national entertainment infrastructure: with online television gaining momentum and a spin-off of The Hills dropping soon, bandwidth has to be stretched to the breaking point as it is.

'World's fastest WiFi' uses 'lasers'

by Tim Stevens posted Sep 12th 2008 at 10:39AM

We love the smell of a "world's fastest" or "world's largest" claim in the morning. This time it's a team of researchers led by Ernesto Ciaramella at the Sant'Anna School of Advanced Studies in Pisa Italy, saying they've developed the "world's fastest WiFi." Their network beams data at an amazing 1.2Tbps over a few kilometers, more than enough to share your entire Kurosawa collection faster than you can say "Yojimbo." So, performance claims are valid, but we're not sure about that "WiFi" part. Data was transmitted using Free Space Optics (FSO), blinking lasers or LEDs that act like fiber optics without the fiber. This means line-of-sight connections only, so if you get frustrated when concrete walls hamper your WiFi downloads imagine how you'd feel if a little puffy cloud killed all your torrents. So, fastest wireless? Check. Practical solution for high-speed wireless communications? Not so much.

CERN creates a new super-fast internet, invites tons of people to a deathmatch

by Joshua Topolsky posted Apr 7th 2008 at 10:29AM

Apparently, when CERN isn't colliding particles (and ripping massive holes in the space-time continuum), it's busy working on a new "internet" which will be 10,000 times faster than our current version. The project -- known as "the grid" -- is built atop completely fiber optic networks, and utilizes modern routing centers. By keeping traffic out of our current phone and data systems, the researchers have been able to achieve speeds heretofore unseen on previous networks. The system connects from CERN to 11 centers around the globe, and will be switched on when the Large Hadron Collider is activated, on what the group is calling "Red Button Day." Project heads believe a network with this speed will lead to all sorts of futuristic innovations -- like true cloud computing, holographic video conferencing, and really, really fast pirating of the entire Nightmare on Elm Street series.

Verizon ups its FiOS speeds to 50Mbps, sets the internet on fire

by Joshua Topolsky posted Nov 21st 2007 at 4:14AM

Not content with blazing up your local connection at 20Mbps downstream and up, Verizon has once again bumped its already-painfully-fast FiOS broadband service into the realm of ridiculous. According to reports, the company is now offering a 30Mbps / 15 Mbps service at $89.95 a month, and the nerve-shattering 50 Mbps / 20 Mbps speed at $139.95. The telecom has also introduced symmetrical connections in all 16 states where it currently offers FiOS service, with a 20Mbps / 20Mbps on the up and down, starting at $64.99. Of course, it's all bleeps and buzzes in our particularly lonely corner of Brooklyn, where we'll have to suffer the indignation of a lowly 10Mbps connection until the big V blesses us with some real speed... you hearing us, dudes?

China and the US are getting hitched (with fiber)

by Thomas Ricker posted Oct 23rd 2007 at 8:41AM

Looks like Chinese and US telco's will do what our governments can't: establish an undeniable bond which is stronger than, uh, glass. Ok, we have that. Nevertheless, work began this week in China on a 18,000-km (11,184-mile) fiber-optic cable between the coastal city of Qingdao and Nedonna Beach, Oregon. Existing cables between China and the US run through Japan. The new link is designed to support 62 million simultaneous calls while handling the anticipated growth from Internet video and e-commerce. With any luck, they'll meet the July target ahead of the Beijing Olympics which starts in August 2008.

Counter-Strike shooting slowed by actual shooting

by Joshua Topolsky posted Aug 21st 2007 at 4:15PM

At around 7 p.m. on Monday, ISPs around the country experienced a period of slowdown, which seemed inexplicable until workers discovered that fiber optic lines in Cleveland, Ohio -- reportedly owned by Level 3 Communications -- had been the target of sabotage... by gunfire. Anders Olausson, a TeliaSonera AB spokesman, said that the company had lost the northern leg of its network, and when technicians pulled up the lines to inspect, it was apparent that, "Somebody had been shooting with a gun or a shotgun into the cable." The damage was spread out over nearly two-thirds of a mile along the lines, and the effect was felt across multiple networks. Cogent Communications warned customers that they would be experiencing outages, and blamed the disruptions on "cut lines," and Keynote's Internet Pulse Report showed that the provider was experiencing significant latency. As of now, the saboteurs remain anonymous and their motives unknown, but undoubtedly scores of WoW players wait in fear of their next attack.

Intel's silicon laser modulator breaks 40Gbps speed barrier

by Joshua Topolsky posted Jul 25th 2007 at 7:46PM

Intel announced today that it has fabricated the first silicon laser modulator to encode optical data at 40Gbps, making it 40 times faster than some of the most sophisticated data networks. The company has been working on silicon-based modulators -- key elements in using lasers as a means of fiber optic data transfer -- for years, creating a 1Gbps version in 2004, and then a 10Gbps iteration in 2006. Intel currently spends thousands producing the modulators now, but it hopes to drive down costs in the near future, allowing for integrated silicon photonic circuits to be built featuring upwards of 25 individual 40Gbps modules, enabling transmissions of terabits of data in seconds. So what does all this scientific doublespeak mean for the hard working computer users of the world? Well let's just say that "stuff" is going to be getting "fast" sooner than you think.

Corning develops bendable fiber optic cable

by Joshua Topolsky posted Jul 24th 2007 at 3:46PM

Corning announced today that it has overcome a major roadblock in the proliferation of fiber optic lines around the world (or at least where Verizon wants to pay to put them in). For years, providers have been struggling against a deficiency in fiber optic cable which causes the pipe to vent light when bent or curved, or lose it entirely if twisted too far. Now, however, researchers at Corning have developed a new variant to keep data moving: tiny, nanostructure "guardrails" that surround the fiber's core. The "rails" keep light from seeping out, yet are flexible enough to be wound around a pencil while delivering a signal at full strength. Corning hasn't put the piping into production yet, but when it does, Verizon says it's ready to use it -- which means pretty soon we're all going to be talking like that annoying kid from the FiOS commercials.

Australian physicists develop teleportation scheme for atoms

by Darren Murph posted Jul 11th 2007 at 4:25AM

Although the idea of teleporting individuals from one place to another in order to sidestep the headache of rush hour traffic has been around for quite some time, a team of Australian physicists are busy making it work (on a smaller scale, of course). Granted, they don't fully expect their teleportation scheme to be used on humans in the near future, but there's always hope, right? Anyway, the team has developed a so-called "simple way to transport atoms," which involves bringing the atoms to almost absolute zero, beaming them with two lasers, and using fiber optics to transport them to any other place at the speed of light where they "enter a second condensate" and reconstruct. We'll keep you posted on when human trialing (hopefully) begins.

Fiber optic tablecloth: the new candlelit dinner

by Darren Murph posted Jun 24th 2007 at 12:24AM

We highly doubt LumiGram's Luminous Fiber Optic Tablecloth was designed with power outages in mind, but why hook up a boring string of lamps or fiddle with half melted candles when you can plug this bad boy into the generator? The cloth, which has fiber optics woven throughout, cotton borders, and a Europlug mains adapter, proves most useful when the lights are dimmed, and should prove quite the centerpiece at your next get-together. The illuminating device is available in a trio of sizes, comes in a variety of color schemes, and will cost you a very unappetizing €949 ($1,270) for the privilege.

$500 million underwater fiber network to link Asia, America

by Darren Murph posted Apr 28th 2007 at 5:15PM

Unfortunately for most, traversing back and forth to Asia from America on a regular basis isn't exactly in the cards, but thanks to a $500 million project agreed upon by a 17-member telecommunications consortium, visiting via fiber will soon be a whole lot snappier. Telekom Malaysia, along with 16 other firms, have awarded a half billion dollar contract to Alcatel-Lucent and NEC to construct a 12,428-mile link between the west coast of America and Southeast Asia. The aptly-dubbed Asia-America Gateway will connect the western US with Malaysia, Singapore, Thailand, Brunei, Hong Kong, the Philippines, Guam, and Hawaii, while also offering "seamless interconnection" with Europe, Africa, and Australia. Moreover, the project is being designed to provide a "more secure link for traffic" across the seas, as it avoids the hazardous Pacific Ring in hopes of dodging massive internet outages due to unexpected earthquakes. Best of all, the wait time for the undersea cabling to make an impact is fairly reasonable, as users should see "faster and more reliable service" when it becomes operational in December of next year.
