BT Runs an 800Gbps Channel On Old Fiber 127

Posted by samzenpus
from the greased-lightning dept.
judgecorp writes "BT has demonstrated an 800Gbps 'superchannel' on a 410km fiber in its core network, which was not able to carry 10Gbps channels using older technology. The superchannel is an advanced dense wave division multiplexing (DWDM) technique, created by combining multiple coherent optical signals into one channel, which had previously been shown in laboratory tests. BT ran the test on a fiber with optical characteristics (high polarization mode dispersion) that made it unsuitable for 10GBps using current techniques. That's a good result for BT, because it means its existing core fiber network can be upgraded to handle more data. It's also a good customer story for Ciena, which makes the optical switches used in the test."

Comment: And an Acer Chromebook isn't torture? (Score 1) 645

Guess he never used^H^H^H^Howned an Acer before. After my laptop underwent half a year of destruction^H^H^H^H^H^H^H^H^H^H^Hrepairs, the repair note said they "reattached the cooling block to the video card". They cleverly had removed it during the first repair. No wonder my laptop died every time within 24 hours after I got it back. After the last repair, they had also put a scratch on my screen, and when I reported it, they said there wasn't a single 15" tft panel left in Europe. I would have to wait for months to have it fixed. One colleague had similar problems. After hearing what happend to our laptops, a second colleague literally ducttaped the disintegrating body of his Acer laptop together instead of sending it in for repair, even though it was still under warranty.

The First Photograph of a Human 138

Posted by samzenpus
from the fist-cheese dept.
wiredog writes "The Atlantic has a brief piece on what is likely to be the first photograph (a daguerreotype) showing a human. From the article: 'In September, Krulwich posted a set of daguerreotypes taken by Charles Fontayne and William Porter in Cincinnati 162 years ago, on September 24, 1848. Krulwich was celebrating the work of the George Eastman House in association with the Public Library of Cincinnati and Hamilton County. Using visible-light microscopy, the George Eastman House scanned several plates depicting the Cincinnati Waterfront so that scholars could zoom in and study the never-before-seen details.'"

Badgers Digging Up Ancient Human Remains 172

from the someone-get-a-snake dept.
One of England's oldest graveyards is under siege by badgers. Rev Simon Shouler now regularly patrols the grounds of St. Remigius Church looking for bones that the badgers have dug up. The badger is a protected species in England so they can not be killed, and attempts to have them relocated have been blocked by English Nature. From the article: "At least four graves have been disturbed so far; in one instance a child found a leg bone and took it home to his parents. ... Rev. Simon Shouler has been forced to carry out regular patrols to pick up stray bones, store them and re-inter them all in a new grave."

Fine-Structure Constant Maybe Not So Constant 105

Posted by samzenpus
from the variety-is-the-spice-of-life dept.
Kilrah_il writes "The fine-structure constant, a coupling constant characterizing the strength of the electromagnetic interaction, has been measured lately by scientists from the University of New South Wales in Sydney, Australia and has been found to change slightly in light sent from quasars in galaxies as far back as 12 billion years ago. Although the results look promising, caution is advised: 'This would be sensational if it were real, but I'm still not completely convinced that it's not simply systematic errors' in the data, comments cosmologist Max Tegmark of MIT. Craig Hogan of the University of Chicago and the Fermi National Accelerator Laboratory in Batavia, Ill., acknowledges that 'it's a competent team and a thorough analysis.' But because the work has such profound implications for physics and requires such a high level of precision measurements, 'it needs more proof before we'll believe it.'"

The Proton Just Got Smaller 289

Posted by samzenpus
from the size-does-matter dept.
inflame writes "A new paper published in Nature has said that the proton may be smaller than we previously thought. The article states 'The difference is so infinitesimal that it might defy belief that anyone, even physicists, would care. But the new measurements could mean that there is a gap in existing theories of quantum mechanics. "It's a very serious discrepancy," says Ingo Sick, a physicist at the University of Basel in Switzerland, who has tried to reconcile the finding with four decades of previous measurements. "There is really something seriously wrong someplace."' Would this indicate new physics if proven?"

German Airports Use Bees To Monitor Air Quality 44

Posted by samzenpus
from the smog-honey dept.
The Düsseldorf International Airport and seven other airports in Germany have come up with a unique way of monitoring air quality; they use bees. The airports test the bees' honey twice a year for toxins, and batches that turn up clean are bottled and given away. From the article: "Assessing environmental health using bees as 'terrestrial bioindicators' is a fairly new undertaking, said Jamie Ellis, assistant professor of entomology at the Honey Bee Research and Extension Laboratory, University of Florida in Gainesville. 'We all believe it can be done, but translating the results into real-world solutions or answers may be a little premature.' Still, similar work with insects to gauge water quality has long been successful."

A Quantum Memory Storage Prototype 114

Posted by Soulskill
from the spooky-action-down-under dept.
eldavojohn writes "An Australian National University project has completed a proof-of-concept storage unit that relies on bringing light to a standstill inside a crystal and then releasing it later for a read-once storage device. There are a few complexities to work out, such as the -270 degrees Celsius requirement to stop the light. And there is an interesting side effect noted by the team lead: 'We could entangle the quantum state of two memories, that is, two crystals. According to quantum mechanics, reading out one memory will instantly alter what is stored in the other, no matter how large the distance between them. According to relativity, the way time passes for one memory is affected by how it moves. With a good quantum memory, an experiment to measure how these fundamental effects interact could be as simple as putting one crystal in the back of my car and going for a drive.' Hopefully this will lead to a better understanding and simple testing of quantum entanglement."

How Sperm Whales Offset Their Carbon Footprint 150 Screenshot-sm

Posted by samzenpus
from the all-natural-solution dept.
Boy Wunda writes "Scientists at Flinders University in South Australia found that in an awesome example of design by Mother Nature, Southern Ocean sperm whales offset their carbon footprint by simply defecating – an action that releases tons of iron a year and stimulates the growth of phytoplankton which absorb and trap carbon dioxide. If only we humans could say the same for our poop, which really doesn't do much more than just sit there." I'm going to do my part by buying some iron supplements and a can of chili, and heading off toward the ocean.

Israeli Startup Claims SSD Breakthrough 159

from the believe-in-what-you-write dept.
Lucas123 writes "Anobit Technologies announced it has come to market with its first solid state drive using a proprietary processor intended to boost reliability in a big way. In addition to the usual hardware-based ECC already present on most non-volatile memory products, the new drive's processor will add an additional layer of error correction, boosting the reliability of consumer-class (multi-level cell) NAND to that of expensive, data center-class (single-level cell) NAND. 'Anobit is the first company to commercialize its signal-processing technology, which uses software in the controller to increase the signal-to-noise ratio, making it possible to continue reading data even as electrical interference increases.' The company claims its processor, which is already being used by other SSD manufacturers, can sustain up to 4TB worth of writes per day for five years, or more than 50,000 program/erase cycles — as contrasted with the 3,000 cycles typically achieved by MLC drives. The company is not revealing pricing yet."

eldavojohn writes "Sure, they're stepping all over proprietary rights and copyright, but something must be said about the amount of bliss-filled nostalgia inside Exploding Rabbit's Super Mario Crossover. If the plumbers never really did it for you, you can now kill those goombas as Link, Mega Man, Samus, Simon Belmont, or Contra's Bill. Goodbye jumping and spitting; hello slicing, whipping, and shooting. Is this one of the early firsts in the new genre of video game mashups?"
