Small Fujitsu Device Harvests Both Solar and Thermal Energy 36

Posted by Soulskill on Saturday December 11, 2010 @06:37PM from the things-to-wallpaper-your-EV-with dept.

destinyland writes "Fujitsu has built a device that can simultaneously harvest energy from either light or heat. They've reduced production costs by using the same cheap organic substrate for both conversion processes, while also doubling the potential amount of energy that can be collected. 'Previously, dual harvesting of energy could only be done by combining two different devices,' the article notes — and the device's solar converter can even draw energy from indoor lighting as well as direct sunlight. Fujitsu predicts the device will be especially useful for powering medical sensors, since the flexible substrate can be included in monitors which conform to the shape of the human body."

New Imaging Method Reveals Brain Connections 95

Posted by samzenpus on Wednesday November 17, 2010 @07:37PM from the look-at-the-big-brain-on-you dept.

An anonymous reader writes "Researchers at the Stanford University School of Medicine, applying a state-of-the-art imaging system to brain-tissue samples from mice, have been able to quickly and accurately locate and count the myriad connections between nerve cells in unprecedented detail, as well as to capture and catalog those connections' surprising variety. A typical healthy human brain contains about 200 billion nerve cells, or neurons, linked to one another via hundreds of trillions of tiny contacts called synapses. It is at these synapses that an electrical impulse traveling along one neuron is relayed to another, either enhancing or inhibiting the likelihood that the second nerve will fire an impulse of its own. One neuron may make as many as tens of thousands of synaptic contacts with other neurons, said Stephen Smith, PhD, professor of molecular and cellular physiology and senior author of a paper describing the study, to be published Nov. 18 in Neuron."

Proposed Final ACTA Text Published 148

Posted by timothy on Tuesday November 16, 2010 @06:09PM from the oh-honey-let's-do-some-actas dept.

ciaran_o_riordan writes "The US Trade Representative has published a text which, subject only to a last legal review, is proposed to be the final text of ACTA. The differences between this text and last month's, from the Tokyo round, are mostly cosmetic but there's an important positive change giving signatories the option of excluding patents from section 2. As for software patents, most harm has been avoided. If signatories make use of the section 2 exclusion option, there might be no harm at all. Lobbying for this will be important. Meanwhile, the many problems regarding Digital Restrictions Management, and the extra powers given to businesses to obtain personal and identifying information about accused copyright infringers "in the Digital Environment" are still there (mostly section 5). Earlier texts were much worse. The improvements in recent months are surely due to public outcry, leaving us indebted to the anonymous friends who scanned and leaked the various secret versions and the activists who made text versions and spread them across the Internet. There's a chance we can still influence the text in this legal review phase, but the bigger task ahead will be working on the national implementations. It's not yet clear what procedure the US will require for its own ratification."

Most Detailed View of Dark Matter Mapped By Hubble 93

Posted by CmdrTaco on Tuesday November 16, 2010 @05:27PM from the final-frontier dept.

astroengine writes "Building on previous studies by the Hubble Space Telescope, new analysis of gravitational lensing data has revealed the most detailed map of the distribution of dark matter yet. The distribution appears as a beautiful ghost-like or ethereal haze and could have serious ramifications on our understanding as to how galaxy clusters form and evolve."

Net Neutrality Supporters Hammered In Elections 402

Posted by samzenpus on Wednesday November 03, 2010 @06:28PM from the alignment-shift dept.

Pickens writes "Gigi Sohn writes in the Huffington Post that one of the results of the mid-term elections was the defeat of Representative Rick Boucher, the current Chair of the House Subcommittee on Communications, Technology and the Internet, widely recognized as one of the most tech-savvy and intelligent members of Congress, and long an advocate for consumers on a wide variety of communications and intellectual property issues. Boucher has been the best friend of fair use on Capitol Hill writes Sohn. In 2002, 2003 and 2007, Boucher introduced legislation to allow consumers to break digital locks for lawful purposes, a fair use exception to the anti-circumvention provisions of the Digital Millennium Copyright Act, and while the odds against that legislation passing were always great, Boucher understood the symbolic importance of standing up for consumers' rights to use technology lawfully. 'As important, he served as a moderating force both on the House Energy & Commerce and Judiciary Committees against those many members of Congress willing to give large media companies virtually everything on their copyright wish lists.'"

Shuttle Launch Delayed Again, Possibly Until December 111

Posted by samzenpus on Wednesday November 03, 2010 @03:35PM from the catch-you-next-month dept.

An anonymous reader writes "NASA engineers worked overnight trying to fix the electrical problem that forced the launch of space shuttle Discovery to be delayed again. Mission managers will meet later Wednesday to figure out if a launch on Thursday is even possible. The tentative plan is to have Discovery lift off Thursday at 3:29pm. If that does not happen it would be rescheduled for Sunday. If it cannot launch Sunday then it will have to wait until December. NASA engineers have a lot of work on their hands Wednesday morning. Discovery has an electrical issue that forced officials to postpone its liftoff, which had been rescheduled for Wednesday afternoon."

ACLU Says Net Neutrality Necessary For Free Speech 283

Posted by CmdrTaco on Wednesday October 20, 2010 @09:30AM from the thanks-for-listening dept.

eldavojohn writes "The ACLU has recently identified Network Neutrality a key free speech issue and said in a lengthy PDF report: 'Freedom of expression isn't worth much if the forums where people actually make use of it are not themselves free. And the Internet is without doubt the primary place where Americans exercise their right to free expression. It's a newspaper, an entertainment medium, a reference work, a therapist's office, a soapbox, a debating stand. It is the closest thing ever invented to a true "free market" of ideas.' The report then goes on to argue that ISPs have incentive and capability of interfering with internet traffic. And not only that but the argument that it is only 'theoretical' are bogus given they list ten high profile cases of it actually happening. If the ACLU can successfully argue that Net Neutrality is a First Amendment Issue then it might not matter what businesses (who fall on either side of the issue) want the government to do."

Brilliant Pics of Bizarre Sea Critters 63

Posted by CmdrTaco on Monday October 04, 2010 @12:46PM from the tales-from-mos-eisley-cantina dept.

An anonymous reader writes "Today, scientists have announced the completion of the first ever Census of Marine Life. The colossal 10-year effort involved 2,700 researchers from 80 countries. To mark the occasion, Discover's blog 80beats has a photo gallery of some of the most marvelously strange sea creatures photographed in the course of the census. The blog post also explains some of the census's most important findings, including the dramatic decline of many commercially important large marine animals, and troubling new evidence of a decline in the phytoplankton that serves as the base of the marine food chain."

Genetically Altering Trees To Sequester More Carbon 279

Posted by Soulskill on Saturday October 02, 2010 @02:25PM from the increasing-the-world's-suv-capacity dept.

An anonymous reader writes "Forests of genetically altered trees and other plants could sequester several billion tons of carbon from the atmosphere each year and so help ameliorate global warming, according to estimates published in the October issue of BioScience. The study, by researchers at Lawrence Berkeley National Laboratory and Oak Ridge National Laboratory, outlines a variety of strategies (PDF) for augmenting the processes that plants use to sequester carbon dioxide from the air and convert it into long-lived forms of carbon, first in vegetation and ultimately in soil."

Masterpieces Online — High Culture At High Resolution 99

Posted by Soulskill on Saturday October 02, 2010 @11:59AM from the extreme-close-up dept.

crimeandpunishment writes "You can now see the finest details of some of the finest Italian masterpieces with just one click of your mouse. High-resolution images of classic paintings by Leonardo da Vinci, Caravaggio, and Botticelli are now online with that opportunity. You can zoom in to the smallest details, even ones you wouldn't see when viewing the paintings in person at a museum. The images have a resolution of up to 28 billion pixels, which is about 3,000 times more than a photo from an average digital camera."

Levitating Graphene Is Fastest-Spinning Object 146

Posted by CmdrTaco on Thursday September 30, 2010 @11:25AM from the onesies-twosies dept.

techbeat writes "A flake of exotic carbon a few atoms thick has claimed a record: the speck has been spun faster than any other object, at a clip of 60 million rotations per minute. Previously, micrometre-sized crystals have been spun at up to 30,000 rpm using an optical trap. It is thanks to graphene's amazing strength that the flakes are not pulled apart by the much higher spinning rate, says Bruce Kane at the University of Maryland in College Park. Spinning could be a way to probe the properties of graphene, or manipulate it in new ways."

Red Hat Urges USPTO To Deny Most Software Patents 175

Posted by samzenpus on Thursday September 30, 2010 @02:34AM from the stop-giving-it-away dept.

Julie188 writes "The United States Patent and Trademark Office asked for public input on how it should use the Supreme Court's Bilski decision to guide it when granting new patents. Not surprisingly, Red Hat took them up on it. The USPTO should use Bilski and the fact that the machine transformation test is 'important' to Just Say No to most software patents, it advised. Rob Tiller, Red Hat's Vice President and Assistant General Counsel, IP, is hopeful that the patent office will listen and put an end to the crazy software patent situation that has turned patents into weapons that hinder innovation."

Songbird Fossil Virus May Help Predict Pandemics 42

Posted by samzenpus on Wednesday September 29, 2010 @11:02PM from the oldest-medicine dept.

An anonymous reader writes "Researchers announced they found a fossil virus hiding in the most unexpected place: the chromosomes of several songbird species. This ancient virus resembles human hepatitis B virus. Finding this ancient virus will catalyze new lines of inquiry that may help scientists predict and prevent future human viral pandemics that originate in birds."

US Gov't Assisted Iranian Gov't Mobile Wiretaps 161

Posted by CmdrTaco on Tuesday September 28, 2010 @04:27PM from the good-for-the-goose dept.

bdsesq sent in a story on Ars Technica highlighting how the US government's drive for security back doors has enabled the Iranian government to spy on its citizens. "For instance, TKTK was lambasted last year for selling telecom equipment to Iran that included the ability to wiretap mobile phones at will. Lost in that uproar was the fact that sophisticated wiretapping capabilities became standard issue for technology thanks to the US government's CALEA rules that require all phone systems, and now broadband systems, to include these capabilities."

UK's Two Biggest ISPs Rip Up Net Neutrality 225

Posted by CmdrTaco on Tuesday September 28, 2010 @02:59PM from the battling-the-inevitable dept.

Barence writes "The UK's two biggest ISPs have openly admitted they'd give priority to certain internet apps or services if companies paid them to do so. Speaking at a Westminster eForum on net neutrality, senior executives from BT and TalkTalk said they would be happy to put selected apps into the fast lane, at the expense of their rivals. Asked specifically if TalkTalk would afford more bandwidth to YouTube than the BBC's iPlayer if Google was prepared to pay, the company's executive director of strategy and regulation, Andrew Heaney, argued it would be 'perfectly normal business practice to discriminate between them.' Meanwhile, BT's Simon Milner said: 'We absolutely could see a situation when content or app providers may want to pay BT for quality of service above best efforts,' although he added BT had never received such an approach."
