Growing Plants on the Moon May Be Feasible 254

Posted by Zonk on Thursday April 17, 2008 @01:11PM from the we-carry-a-harpoon dept.

Smivs writes "European scientists say that growing plants on the moon should be possible. Scientists in the Netherlands believe growing plants on our sister satellite would be useful as a tool to learn how life adapts to lunar conditions. It would also aid in understanding the challenges that might be faced by manned bases. 'The new step, taken in the experiments reported at the EGU, is to remove the need for bringing nutrients and soil from Earth. A team led by Natasha Kozyrovska and Iryna Zaetz from the National Academy of Sciences in Kiev planted marigolds in crushed anorthosite, a type of rock found on Earth which is very similar to much of the lunar surface. In neat anorthosite, the plants fared very badly. But adding different types of bacteria made them thrive; the bacteria appeared to draw elements from the rock that the plants needed, such as potassium.'"

10Gb Ethernet Alliance is Formed 173

Posted by Zonk on Thursday April 17, 2008 @12:27PM from the ethernet-alliance-powers-activate dept.

Lucas123 writes "Nine storage and networking vendors have created a consortium to promote the use of 10GbE. The group views it as the future of a combined LAN/SAN infrastructure. They highlight the spec's ability to pool and virtualize server I/O, storage and network resources and to manage them together to reduce complexity. By combining block and file storage on one network, they say, you can cut costs by 50% and simplify IT administration. 'Compared to 4Gbit/sec Fibre Channel, a 10Gbit/sec Ethernet-based storage infrastructure can cut storage network costs by 30% to 75% and increases bandwidth by 2.5 times.'"

RemyBR writes: "Researchers at Osaka University are stepping up efforts to develop robotic body parts controlled by thought, by placing electrode sheets directly on the surface of the brain. Led by Osaka University Medical School neurosurgery professor Toshiki Yoshimine, the research marks Japan's first foray into invasive (i.e. requiring open-skull surgery) brain-machine interface research on human test subjects. The aim of the research is to develop real-time mind-controlled robotic limbs for the disabled, according to an announcement made at an April 16 symposium in Aichi prefecture.

A Peek at AT&T's New Browser, Pogo 239

Posted by Zonk on Thursday April 17, 2008 @11:54AM from the another-way-to-play dept.

An anonymous reader writes "Ars Technica takes a look at Pogo, a browser from AT&T with new features like a 3-D history and bookmark view. The browser's currently in a private beta and Ars' comments aren't all necessarily glowing — particularly in the areas where performance is concerned. 'It requires Windows XP SP2 or later or Windows Vista, and its minimum hardware are surprisingly steep: a 1.6GHz processor, 2GB of RAM, and a video card with at least 256MB of VRAM. Seem like a bit much for a web browser? It is, and as we found out, these requirements posed some major challenges for us during our testing.'"

US Army Furthers Development of Robotic Suits 233

Posted by Zonk on Thursday April 17, 2008 @11:12AM from the ellen-ripley-is-a-lesson-to-us-all dept.

An anonymous reader writes "The BBC reports on advancements in the US military's robotic exoskeleton program. It's being spearheaded by Sarcos, a research laboratory in Utah. The firm has designed the XOS exoskeleton for US Army use, a lightweight frame that gives the user greater strength and endurance. 'With the exoskeleton on and fully powered up, Rex can easily pull down weight of more than 90 kilos, more than he weighs. For the army the XOS could mean quicker supply lines, or fewer injuries when soldiers need to lift heavy weights or move objects around repeatedly. Initial models would be used as workhorses, on the logistics side. Later models, the army hopes, could go into combat, carrying heavier weapons, or even wounded colleagues.'"

Some 12% of Consumers 'Borrow' Unsecured Wi-Fi 469

Posted by Zonk on Thursday April 17, 2008 @10:27AM from the other-88-percent-are-lying dept.

alphadogg writes "Despite the fact that it's often considered an illegal act, a sizeable percentage of the UK/US internet-using population 'borrows' unsecured Wi-Fi access. This is according to a study conducted by the group Accenture. 'The Accenture study found that computer users are still engaging in some unsafe computing practices. Nearly half of all respondents said that they used the same password for all of their online accounts, and only a quarter of them have ever encrypted files on their computers.'" My guess is the actual figure is higher than that.

Red Hat Avoids Desktop Linux, Says Too Tough 472

Posted by Zonk on Thursday April 17, 2008 @09:52AM from the choosing-where-to-fight-your-battles dept.

eldavojohn writes "We recently discussed the Linux Foundation's decision to leave desktop Linux alone but Red Hat is also steering clear of that goal. The reason? It's too tough. From the company blog: 'It's worth pointing out what's missing in the list above: we have no plans to create a traditional desktop product for the consumer market in the foreseeable future. An explanation: as a public, for-profit company, Red Hat must create products and technologies with an eye on the bottom line, and with desktops this is much harder to do than with servers.'"

Senator Proposes to Monitor All P2P Traffic for Illegal Files 626

Posted by Zonk on Thursday April 17, 2008 @09:19AM from the kind-of-strains-the-mind-to-think-about-huh dept.

mytrip writes "Senator Joe Biden (D-Del) has proposed an ambitious plan, costing on the order of $1 billion, aimed at curtailing illegal activities via P2P networks. His plan involves utilizing new software to monitor peer-to-peer traffic on an ongoing basis. 'At an afternoon Senate Judiciary subcommittee hearing about child exploitation on the Internet, Sen. Joe Biden (D-Del.) said he was under the impression it's "pretty easy to pick out the person engaged in either transmitting or downloading violent scenes of rape, molestation" simply by looking at file names. He urged use of those techniques by investigators to help nab the most egregious offenders."

Linus Announces the 2.6.25 Linux Kernel 181

Posted by Zonk on Thursday April 17, 2008 @08:40AM from the those-servers-need-a-workout dept.

LinuxWatch writes "'It's been long promised, but there it is now,' began Linux creator Linus Torvalds, announcing the 2.6.25 Linux kernel. He continued, 'special thanks to Ingo who found and fixed a nasty-looking regression that turned out to not be a regression at all, but an old bug that just had not been triggering as reliably before. That said, that was just the last particular regression fix I was holding things up for, and it's not like there weren't a lot of other fixes too, they just didn't end up being the final things that triggered my particular worries.' There were numerous changes in this revision of the OS. The origins of some of those fixes is detailed in Heise's brief history of this kernel update."

The Inside Story of the Armed Robot Pullout Rumor 105

Posted by Zonk on Wednesday April 16, 2008 @07:31PM from the see-how-these-things-get-started dept.

An anonymous reader writes "It appears that the initial rumor of the SWORDS robots being pulled out of Iraq — and its subsequent correction — were just that: sensationalizing in the blogosphere. Popular Mechanics has a lengthy update to its original scoop, digging into the sketchy responses from defense contractors when pressed about the bot's actual duties in battle. From the article: 'Although others have used our story to generate a false online rumor about these armed UGVs, the nature of those "technical issues" that Gotvald mentioned in his statement, and that Qinetiq and Foster-Miller have yet to address directly, remains a mystery. Until someone can explain why SWORDS lost its funding, and what exactly it is — and isn't — being used for in Iraq, the rumors are likely to continue. If this is the dawn of the era of robotic infantry, things are off to a decidedly rocky start.""

Computers Emulate Neanderthal Speech 220

Posted by Zonk on Wednesday April 16, 2008 @06:34PM from the borrow-a-cup-of-evolution dept.

Clarence writes "After some 30,000 years of silence, the Neanderthal race is once again speaking thanks to some advanced computer simulation. A Florida Atlantic University professor is using software vocal tract reconstructions to emulate the speech of our long-dead distant relatives. 'He says the ancient human's speech lacked the "quantal vowel" sounds that underlie modern speech. Quantal vowels provide cues that help speakers with different size vocal tracts understand one another, says Robert McCarthy, who was talking at the annual meeting of the American Association of Physical Anthropologists in Columbus, Ohio, on April 11. In the 1970s, linguist Phil Lieberman, of Brown University in Providence, Rhode Island, inferred the dimensions of the larynx of a Neanderthal based on its skull. His team concluded that Neanderthal speech did not have the subtlety of modern human speech.'"

Hardy Heron Making Linux Ready for the Masses? 1100

Posted by Zonk on Wednesday April 16, 2008 @05:55PM from the it-is-a-very-robust-bird dept.

desmondhaynes writes "Is Linux ready for the masses? Is Linux really being targeted towards the 'casual computer user'? Computerworld thinks we're getting there, talking of Linux 'going mainstream 'with Ubuntu. 'If there is a single complaint that is laid at the feet of Linux time and time again, it's that the operating system is too complicated and arcane for casual computer users to tolerate. You can't ask newbies to install device drivers or recompile the kernel, naysayers argue. Of course, many of those criticisms date back to the bad old days, but Ubuntu, the user-friendly distribution sponsored by Mark Shuttleworth's Canonical Ltd., has made a mission out of dispelling such complaints entirely.'"

Google Crawls The Deep Web 197

Posted by Zonk on Wednesday April 16, 2008 @05:13PM from the delved-too-deeply dept.

mikkl666 writes "In their official blog, Google announces that they are experimenting with technologies to index the Deep Web, i.e. the sites hidden behind forms, in order to be 'the gateway to large volumes of data beyond the normal scope of search engines'. For that purpose, the engine tries to automatically get past the forms: 'For text boxes, our computers automatically choose words from the site that has the form; for select menus, check boxes, and radio buttons on the form, we choose from among the values of the HTML'. Nevertheless, directions like 'nofollow' and 'noindex' are still respected, so sites can still be excluded from this type of search.'"

Folding@home GPU2 Beta Released, Examined 149

Posted by Zonk on Wednesday April 16, 2008 @04:35PM from the nice-to-give-my-console-a-hobby dept.

ThinSkin writes "Stanford has recently released an update to their Folding@home GPU-accelerated client, which includes notable upgrades such as support for more current Radeon graphics cards and even a visualizer to see what's going on. ExtremeTech takes a good look at the new Folding@home GPU2 client and interviews Director Dr. Vijay Pande about the project. To the uninitiated, Folding@home is a distributed computing project in which hundreds of thousands of PCs and PS3s devote a portion of their computing power to crunch chunks of biological data. The goal is 'to understand protein folding, misfolding, and related diseases.'"

Consumer Groups Advocate for 'Do Not Track' Registry 146

Posted by Zonk on Wednesday April 16, 2008 @03:53PM from the it's-nice-to-dream dept.

eldavojohn writes "Consumer groups are asking for a 'do not track' registry to be implemented, similar to the successful and popular 'do not call' registry. Tracking companies are asking for examples where tracking has caused harm, and would rather the industry stay self-regulated. 'In December, the FTC approved Google's purchase of advertising rival DoubleClick over the objections of some privacy groups. At the same time, the agency urged advertisers to let computer users bar advertisers from collecting information on them, to provide "reasonable security" for any data and to collect data on health conditions or other sensitive issues only with the consumer's express consent.'"
