US Broadband Won't Catch Up With Japan's For 101 Years
An anonymous reader writes "Internet speeds of users nationwide shows that the United States has not made significant improvements in deploying high-speed broadband networks in the past year, and if the average US Internet speed continues to improve only at the same rate it did from 2007 to 2008, the country won't catch up with Japan's current download speed for another 100 years, according to findings released by the Communications Workers of America's (CWA's) Speed Matters campaign." With enough statistical mangling, nearly anything can be presented as plausible, but that's not enough to cover up my envy of Asian broadband speeds. -
Nano Safety Worries Scientists More Than Public
Nanotech Coward writes "The unknown human health and environmental impacts of nanotechnology are a bigger worry for scientists than for the public, according to a new report in the journal Nature Nanotechnology. The new report was based on a national telephone survey of American households and a sampling of 363 leading U.S. nanotechnology scientists and engineers. It reveals that those with the most insight into a technology with enormous potential — and that is already emerging in hundreds of products — are unsure what health and environmental problems might be posed by the technology." -
Internet Bandwidth to Become a Global Currency?
ClimateCrisis writes to tell us that internet bandwidth could become a global currency under a new model of e-commerce developed by researchers from Delft University of Technology, Vrije Universiteit, Amsterdam and Harvard's School of Engineering and Applied Sciences. "The application, available for free download at http://TV.seas.harvard.edu, is an enhanced version of a program called Tribler, originally created by the Dutch collaborators to study video file sharing. 'Successful peer-to-peer systems rely on designing rules that promote fair sharing of resources amongst users. Thus, they are both efficient and powerful computational and economic systems,' David Parkes, John L. Loeb Associate Professor of the Natural Sciences at Harvard said. 'Peer-to-peer has received a bad rap, however, because of its frequent association with illegal music or software downloads.' The researchers were inspired to use a version of the Tribler video sharing software as a model for an e-commerce system because of such flexibility, speed, and reliability." -
Rocket-Powered Bionic Arm Successfully Tested
amigoro writes "A rocket-powered bionic arm has been successfully developed and tested by a team of mechanical engineers at Vanderbilt University as part of a $30 million military program to develop advanced prosthetic devices for next generation of super-soldiers." -
Another Way To Erase Memories
amigoro writes "Neuroscientists have discovered that long-term memories are not etched in a stable form, like a 'clay tablet,' as once thought. The process is much more dynamic, involving a miniature molecular machine that must run constantly to keep memories going. Jamming the machine briefly can erase long-term memories." A few months back we discussed a similar removal of rat memories by a different method. -
Privacy Winning Search Engine War
amigoro writes "Privacy is emerging as the real winner of the Internet search engine war as companies aggressively compete with one another by offering stronger protections for user records, a report published today by the Center for Democracy and Technology concluded. The report notes that until recently, most of the major Internet search engines kept detailed and potentially personally identifiable records of their customers' searches indefinitely. But today the companies are trying to outdo each other in privacy protection by announcing steps to delete old user data, strip the personally identifiable information out of stored search records, and, in one case, give users the option to have all of their search records deleted." -
US Paperless Voting Bill Advances
A couple of weeks back we discussed the effort to require voting paper trails in US federal elections. Now WhiteBoxVoter writes: "Democrats and Republicans in the US House of Representatives agreed today on a compromise that will push through a bill banning paperless voting machines and requiring a voter-verified paper record for every vote in the country, after government sanctioned hackers showed how they could break into all three of the top voting systems used in California." The NYTimes reported on Thursday that even if it passes the House, voting-machine reform that would take effect before the 2008 elections may die in the Senate. -
Senators Call for Universal Internet Filtering
An Anonymous Coward writes "US senators today made a bipartisan call for the universal implementation of filtering and monitoring technologies on the Internet in order to protect children. Their statement came at the end of a Senate hearing in which civil liberties groups were not invited." -
HIV Vaccine Ready For Clinical Trials
amigoro writes with the happy news that a possible vaccine against HIV is nearing readiness for clinical trials. The compound could provide a 'double whammy' by not only inoculating the patient against future infection, but destroying an HIV infection in progress. "The vaccine is an artificial virus-like particle whose outer casing consists of the TBI (T- and B cell epitopes containing immunogen) protein constructed by the researchers combined with the polyglucin protein. This protein contains nine components stimulating different cells of the immune system: both the ones that produce antibodies and the ones that devour the newcomer." -
Senate Committee Passes FCC Indecency Bill
An anonymous reader writes "US Senate Commerce Committee today passed a bill that would allow the FCC to fine broadcasters for slip of the tongue expletives, negating a ruling by federal appeals court in New York that commission's policy on 'fleeting expletives' is arbitrary and capricious. 'A mandate by Congress that a "fleeting expletive" can now be found indecent will create a vast chilling effect on broadcast speech, the advocacy group Center for Democracy and Technology claims. CDT points out that prior to this bill and the FCC's policy change, the FCC exercised discretion in determining which utterances were indecent, and consistently found that one-time uses of curse words were not indecent.'" -
Ubiquitous Multi-Gigabit Wireless Within Three Years
Anonymous Howard passed us a link to the Press Escape blog, and a post about the future of ultra-fast wireless connectivity. Georgia Tech researchers unveiled plans to use ultra-high frequency radio transmissions to achieve very high data transmission rates over short distances. In a few years, the article says, we'll have ubiquitous multi-gigabit wireless connectivity, with some significant advances already under their belts. "GEDC team have already achieved wireless data-transfer rates of 15 gigabits per second (Gbps) at a distance of 1 meter, 10 Gbps at 2 meters and 5 Gbps at 5 meters. 'The goal here is to maximize data throughput to make possible a host of new wireless applications for home and office connectivity,' said Prof. Joy Laskar, GEDC director and lead researcher on the project along with Stephane Pinel. Pinel is confident that Very high speed, p2p data connections could be available potentially in less than two years. The research could lead to devices such as external hard drives, laptop computers, MP-3 players, cell phones, commercial kiosks and others could transfer huge amounts of data in seconds while data centers could install racks of servers without the customary jumble of wires." -
True Random Number Generator Goes Online
amigoro writes "A 'true' random number generator that relies on the unpredictable quantum process of photon emission has gone online providing academic and scientific community access to true random numbers free of charge." -
MIT Finds Cure For Fear
Doom con runs away writes "MIT biochemists have identified a molecular mechanism behind fear, and successfully cured it in mice, according to an article in the journal Nature Neuroscience. They did this by inhibiting a kinase, an enzyme that change proteins, called Cdk5, which facilitates the extinction of fear learned in a particular context." -
World's Fastest Broadband Connection — 40 Gbps
paulraps writes "A 75-year-old woman from Karlstad in central Sweden has been given a scorching 40 Gbps internet connection — the fastest residential connection anywhere in the world. Sigbritt Löthberg is the mother of Swedish internet guru Peter Löthberg, who is using his mother to prove that fiber networks can deliver a cost-effective, ultra-fast connection. Sigbritt, who has never owned a computer before, can now watch 1,500 HDTV channels simultaneously or download a whole high definition DVD in two seconds. Apparently 'the hardest part of the whole project was installing Windows on Sigbritt's PC.'" An article in Press Esc notes an analyst study of the increasing demand for fiber-to-the-home in Europe. -
Scientists Find Water on Extra-solar Planet
amigoro writes "Scientists have, for the first time, conclusively discovered the presence of water vapour in the atmosphere of a planet beyond our Solar System, according to an article appearing in Nature. They made the discovery by analysing the transit of the gas giant HD 189733b across its star, in the Infrared using data from NASA's Spitzer Space Telescope. HD 189733b is a 'hot jupiter', a gas giant that is roughly the size and mass of Jupiter but orbits very close to the star, so no chance of life there." -
Google Loses Gmail Trademark Case
amigoro writes "A court in Germany today banned Google from using the name 'Gmail' for its popular webmail service following a trademark suit filed by the founder of G-Mail. Daniel Giersch, started using the name G-Mail in 2000, four years before Google released 'Gmail'. "Google infringed the young businessman's trademark that had been previously been registered," said the Hanseatic Higher Regional Court in its judgement." -
People Trust Yahoo! and Google For the Brands
amigoro writes "Here's an interesting experiment: Copy Google results pages from four different e-commerce queries. Tell 32 test subjects who are going to evaluate the results that the results were from four different search engines: Google, MSN Live Search, Yahoo! and an in-house engine created for the study. Then see which ones they rate as the best. As it turns out Google and Yahoo! win hands down, proving that even on the Internet it's all about branding." -
FBI Seeks To Restrict University Student Freedoms
amigoro writes with a link to the Press Escape blog, which is discussing new guidelines suggest by the FBI for university administrations. The Federal Bureau, worried about the possibility of international espionage via our centers of learning, now sees the need to restrict the freedoms of university students for national security. "FBI is offering to brief faculty, students and staff on what it calls 'espionage indicators' aimed at identifying foreign agents. Unexplained affluence, failing to report overseas travel, showing unusual interest in information outside the job scope, keeping unusual work hours, unreported contacts with foreign nationals, unreported contact with foreign government, military, or intelligence officials, attempting to gain new accesses without the need to know, and unexplained absences are all considered potential espionage indicators." -
Black Hole Information Loss Paradox Solution Proposed
Anuborn Satirak writes to tell us that Physicists from Case Western Reserve University claim to have cracked the black hole information loss paradox that has puzzled physicists for the past 40 years. "The physicists are quick to assure astronomers and astrophysicists that what is observed in gravity pulling masses together still holds true, but what is controversial about the new finding is that 'from an external viewer's point it takes an infinite amount of time to form an event horizon and that the clock for the objects falling into the black hole appears to slow down to zero,' said Krauss, director of Case's Center for Education and Research in Cosmology." -
Scientists Attempt to Replace Crude Oil With Sugars
amigoro writes with a link to the Press Esc blog, discussing a possible replacement for crude oil in plastics, fuels, and other industrial uses. The post outlines findings to be published in an upcoming issue of the journal Science. Essentially, researchers at the Institute for Interfacial Catalysis are attempting to process the sugars in plant matter into an oil-like compound, a daunting challenge. "Glucose, in plant starch and cellulose, is nature's most abundant sugar. 'But getting a commercially viable yield of HMF from glucose has been very challenging,' Zhang said. 'In addition to low yield until now, we always generate many different byproducts,' including levulinic acid, making product purification expensive and uncompetitive with petroleum-based chemicals. Zhang, lead author and former post doc Haibo Zhao, and colleagues John Holladay and Heather Brown, all from PNNL, were able to coax HMF yields upward of 70 percent from glucose and nearly 90 percent from fructose while leaving only traces of acid impurities." -
Plants 'Recognize' Their Siblings
An anonymous reader writes to tell us that according to a recent study, Biologists have found that plants are able to recognize their own relatives. "Researchers at McMaster University have found that plants get fiercely competitive when forced to share their pot with strangers of the same species, but they're accommodating when potted with their siblings. [...] Though they lack cognition and memory, the study shows plants are capable of complex social behaviours such as altruism towards relatives, says Dudley. Like humans, the most interesting behaviours occur beneath the surface." -
White House Derails Attempts to End Illegal Wiretapping
P. Rivacy writes "If you recall, last month we discussed Congress's attempts to outlaw the already illegal NSA wiretaps authorized by the President. The White House is now using delaying tactics to derail the passage of that bill. Their tactic is to stall on providing documents related to the President's warrantless wiretapping program, despite requests from the Senate Intelligence Committee that is currently reviewing the proposed legislation. '"Another critical priority for congressional oversight is government wiretapping of Americans, conducted under the Foreign Intelligence Surveillance Act, and, illegally, under the President's warrantless wiretapping program," Senator Russ Feingold said. "When the program was finally placed within the FISA process, an opportunity arose for the Administration and the Congress to move forward, under the law. Unfortunately, the Administration has yet to demonstrate a real interest in doing so."'" -
Online Shoppers are Willing to Pay More for Privacy
Caroline Matische writes "People are willing to pay more to buy items from online retailers who make their privacy policies clear, a new Carnegie Mellon University study showed. People were more likely to buy from online merchants with good privacy policies and were also willing to pay about 60 cents extra on a $15 purchase when buying from a site with a privacy policy they liked." -
Electrical Field Treats Brain Cancer
amigoro writes "A device that specifically targets rapidly growing cancer cells with intermediate frequency electrical fields doubled the survival rates of patients with brain cancer, according to an article apperaring in PNAS. The device uses electrical fields to disrupt tumor growth by interfering with cell division of cancerous cells, causing them to stop proliferating and die off instead of dividing and growing. Healthy brain cells rarely divide and have different electrical properties than cancerous brain cells. This allows the device to target cancer cells without affecting the healthy cells. Essentially no device-related side effects were seenin the clinical trial." -
Study Reveals What Women Want From IT Jobs
amigoro writes "Ever wonder why there are so few women in the IT workplace? It turns out that the typical recruiters sales pitch, which emphasizing job promotion and security, acts to keep women out of the information technology jobs. While about 30 percent indicated they valued careers that afforded them opportunities to perfect skills in technical areas, others said they wanted careers with managerial opportunities. In addition, there was little overlap among the women who reported that managers give up technical skills to develop management skills." -
Bill Bans NSA Eavesdropping
An anonymous reader writes "The US house of representatives today passed a bill outlawing illegal domestic wiretapping by the government. Now government agencies are only allowed to access your private communications under terms of FISA. 'As the Senate Report noted, FISA "was designed . . . to curb the practice by which the Executive Branch may conduct warrantless electronic surveillance on its own unilateral determination that national security justifies it." The Bill ends plans by the Bush Administration that would give the NSA the freedom to pry into the lives of ordinary Americans. The ACLU noted that, despite many recent hearings about 'modernization' and 'technology neutrality,' the administration has not publicly provided Congress with a single example of how current FISA standards have either prevented the intelligence community from using new technologies, or proven unworkable for the agents tasked with following them.'" -
Senate Introduces Strong Privacy Bill
amigoro writes "US Senators introduced a bill that better protects the privacy of citizens' personal information in the face of data security breaches across the country. Key features of the bipartisan legislation include increasing criminal penalties for identity theft involving electronic personal data and making it a crime to intentionally or willfully conceal a security breach involving personal data." -
Jail for Selling Email Lists to Spammers
amigoro writes "UK will start jailing the people who trade in email addresses, or any other personal data. The current Data Protection Act only fines people who do that, but the money one can make from trading in personal information was far higher than the measly GBP 5000 one had to pay if caught. The new regulations will result in a two year prison sentence for violating the Act." -
Cingular, Others Fined For Using Adware
amigoro writes "Cingular, Priceline, and Travelocity have been fined for using adware by the New York Attorney General. The companies will each pay $30K to $35K as penalties and investigatory costs. More importantly, the companies agreed to a series of restrictions and best practices that, while they make eminent sense to consumers, will be loathsome to businesses accustomed to having their way with our computers." -
New Ice Age Theory
amigoro writes "Most believe that the ice ages are the result of subtle changes in Earth's orbit, known as the Milankovitch cycles. According to one scientist, that is not the case. Robert Ehrlich of George Mason University in Fairfax, Virginia, has developed a model which hypothesizes a dimmer switch inside the sun that causes its brightness to rise and fall on timescales of around 100,000 or 41,000 years, exactly the same period as between ice ages on Earth. The main problem with Milankovitch cycles is that they can't explain how the ice ages go from 100,000 year cycle to 41,000 year cycle. The cycles predicted by Ehlrich's model line up with the observations." -
Researchers Find Potential Cure for Cancer
MECC writes "Researchers at Johns Hopkins University may have found a way to kill cancer cells without radiation or toxic chemicals. The group is taking the step of patenting the idea, as this new approach using sugars may hold real potential for the fight against cancer. This is not the first approach to use sugars, the article states, but is (by the researchers' estimation) the most successful. From the article: 'Sampathkumar and his colleagues built upon 20-year-old findings that a short-chain fatty acid called butyrate can slow the spread of cancer cells. In the 1980s, researchers discovered that butyrate, which is formed naturally at high levels in the digestive system by symbiotic bacteria that feed on fibre, can restore healthy cell functioning ... The researchers focused on a sugar called N-acetyl-D-mannosamine, or ManNAc, for short, and created a hybrid molecule by linking ManNAc with butyrate. The hybrid easily penetrates a cell's surface, then is split apart by enzymes inside the cell. Once inside the cell, ManNAc is processed into another sugar known as sialic acid that plays key roles in cancer biology, while butyrate orchestrates the expression of genes responsible for halting the uncontrolled growth of cancer cells.'"
