quixote9 writes "Calorie restriction while maintaining nutrient levels has long been known to dramatically increase life spans. Very different lab animals, from worms to mice, live up to 50% longer (or even more) on the restricted diets. However, so far, nobody has been able to figure out how this works. Scientists at the Salk Institute have found a specific gene in worms (there's a very similar one in people) that is directly involved in the longevity effect. That opens up the interesting possibility that doctors may someday be able to activate that gene directly and we can live long and prosper . . . without giving up chocolate."

mrogers sends us to Infowars for the following news from the UK, "which is fast becoming the front line of the war on privacy": "'Read my lips..."' used to be a figurative saying. Now the British government is considering taking it literally by adding lip reading technology to some of the four million or so surveillance cameras in order identify terrorists and criminals by watching what everyone says. Perhaps the lip-reading cameras and the shouting cameras will find something to talk about."

marcellizot writes "It has taken a while for handheld consoles to crawl from the primordial 8-bit slime to today's apex predator polygon juggling brutes. To illustrate just how much things have advanced over the last 20 years, Pocket Gamer has pulled together a few facts and figures in pretty chart form. Pitting the vital statistics of the critical handhelds of today and yesteryear against one another, there are some interesting facts to be gleaned from this infotainment extravaganza."

John Reid, Home Secretary, has called upon tech manufacturers to improve the security on their gadgets to help with his recent push to frustrate criminals. Inviting Apple, Sony, and several others to his crime fighting summit Reid hopes to attack the rising robbery numbers in the most recent Home Office figures.

prostoalex writes "Is music played via customized playlist delivered interactively (i.e., via user participation) or non-interactive (i.e., decisions are made on the server side)? The question does seem metaphysical, but it took Sony BMG Music Entertainment and Yahoo! six years to figure it out via a protracted legal battle. User-driven playlists are bucketed with on-demand music services, while server-driven playlists are equaled to broadcasts, thereby causing different licensing mechanisms to take place. Yahoo! inherited the legal wrangle when it purchased a music startup Launch, which built a music recommendation feature. The court decision determined that recommendation algorithms that rely on usage data to build playlists server-side are still eligible for broadcast license, thereby substantially lowering the costs of operating a music recommendation site."

twilight30 wrote us with a link to an article in the Globe and Mail. If further study bears out the findings, new research into the causative agents behind disease and cancer may have a drastic impact on the health of citizens in Canada and the US. According to a four-year clinical trial, there's a direct link between cancer and Vitamin D deficiency. "[The] trial involving 1,200 women, and found those taking the vitamin had about a 60-per-cent reduction in cancer incidence, compared with those who didn't take it, a drop so large — twice the impact on cancer attributed to smoking — it almost looks like a typographical error. And in an era of pricey medical advances, the reduction seems even more remarkable because it was achieved with an over-the-counter supplement costing pennies a day. One of the researchers who made the discovery, professor of medicine Robert Heaney of Creighton University in Nebraska, says vitamin D deficiency is showing up in so many illnesses besides cancer that nearly all disease figures in Canada and the U.S. will need to be re-evaluated. 'We don't really know what the status of chronic disease is in the North American population,' he said, 'until we normalize vitamin D status.'"

An anonymous reader writes "Despite reports, it seems Microsoft is not only alive, but has been thriving these last few months. Following Apple's solid earnings yesterday comes above-expectation reporting from Microsoft. Profits jumped 65% from the previous year, and sales of its Windows operating system were strong: 'Microsoft said it deferred $1.2 billion in Windows Vista revenue to the third quarter, to account for upgrade coupons given to PC buyers during the holiday season before the consumer launch of the new operating system. Excluding this figure, client revenue totaled $4.1 billion, 30 percent higher than last year.' Microsoft Chief Financial Officer Chris Liddell said Vista beat internal forecasts by $300 million to $400 million, and Office 2007 sales were $200 million better than expected."

newtley writes "Wayne Crookes, the Green Party of Canada's ex-financier, is in effect trying to sue the Internet. He's going after the Wikipedia, Google, and openpolitics.ca (run up by federal Green Party activist Michael Pilling) claiming he's suffered, 'an immense amount of frustration and emotional distress' over postings. Some 15 others may also have been targeted. "Mr. Crookes seems to be 'trying to unwrite history,' Pilling says. 'He was a central figure in the growth of the Green Party. His actions were highly controversial and if we have freedom of speech in this country, people should be allowed to talk about them.'" Newtley adds in a posting submitted 121 minutes later: "Literally 15 minutes after I posted [the foregoing], there was a knock on my door. It was a writ server telling me I, too, have been named in a lawsuit launched by Wayne Crookes..."

LandGator wrote with some information about the upcoming Ziggurat Con. Their catch phrase: "Where RPG isn't just a Rocket Propelled Grenade." This very special tabletop gaming event will be held on June 9th of this year ... at Camp Adder /Talil Airbase in Iraq. For nine hours on that day, gamers currently deployed to Iraq will be able to forget about the conflict by rolling dice and playing games. The con organizers are looking for willing folks to donate games and dice to the soldiers, as well as a little recognition for the d20-rolleres in harms way this year. "The Con's historical landmark 'mascot' -- the Ziggurat -- can be found on the post, and hails from the ancient city of Ur. Nearby is the house where it is believed that Abraham (a large figure in the Bible, the Koran and the Torah) was born. Cool digs for a Con -- if not for the fact that there's a war going on. [Convention organizer David] Amberson, however, emphasized the need for soldiers to relax and kick back with enjoyable activities from time to time."

Thib writes "A study from the Pew Internet and American Life Project reveals that the majority of teens pay attention to what they are revealing about themselves in their online social profiles. For instance, while many routinely use their first name or include a picture, 'fewer than a third of teens with profiles use their last names, and a similar number include their e-mail addresses. Only 2 percent list their cell phone numbers.' The study comes to light just as state legislatures once again begin to mutter about the dangers of online predators. From the article: 'According to Pew, 45 percent of online teens do not have profiles at all, a figure that contradicts widespread perceptions that the nation's youths are continually on MySpace.'"

twilight30 asks: "While trying to figure out why a supposedly-supported SATA-II controller isn't recognized on my motherboard I thought I'd go back and visit the Linux Documentation Project's pages. It was a trip down memory lane, but I soon wondered about the state of many of the documents there. Much of TLDP is old, maybe even crufty. So, I'd like to ask what you think of TLDP.org and its 'competitors'. Do people get info from other sites or Wikis? Are people more likely to look at their distro's forums first? Are distros good enough now that TLDP is basically irrelevant? For the BSDheads, do you think the BSDs' documentation pages have lessons to teach TLDP? Is TLDP still relevant to you? If not, what would have to change for TLDP to become relevant again?"

Magnifico writes "The New York times is running an article about a push by American universities to actively recruit women into Computer Science courses. The story, 'Computer Science Takes Steps to Bring Women to the Fold', explains that the number of women in CS is shrinking: 'Women received about 38 percent of the computer science bachelor's degrees awarded in the United States in 1985, the peak year, but in 2003, the figure was only about 28 percent, according to the National Science Foundation.' One of the largest barriers to recruiting women to the field is the nerd factor. To attract women students to the CS field, 'Moving emphasis away from programming proficiency was a key to the success of programs Dr. Blum and her colleagues at Carnegie Mellon instituted to draw more women into computer science.' Changes at CMU increased women students in the CS program from 8 percent to nearly 40 percent."

techdirt writes "It's not like it hasn't been said many times before, but it's nice to see the NY Times running an opinion piece about the RIAA from a pair of record store owners which basically points out how at every opportunity, the RIAA has made the wrong move and made things worse: 'The major labels wanted to kill the single. Instead they killed the album. The association wanted to kill Napster. Instead it killed the compact disc. And today it's not just record stores that are in trouble, but the labels themselves, now belatedly embracing the Internet revolution without having quite figured out how to make it pay.' It's not every day that you see a NY Times piece use the word 'boneheadedness' to describe the strategy of an organization."

PetManimal writes "Despite all of the positive buzz about the Mac operating system and the 'halo effect' of iPod sales, Mac OS X market share actually dropped last month, reports Computerworld: 'The share of PowerPC-based Macs fell ... from 4.29% in February to 3.94% in March. That dip was not fully offset by an increase in Intel-based Mac hardware, leading to a overall net decline in Mac share of 0.3%, to 6.08% in March.' Meanwhile, Vista is rising, the article says, with just over 2% of computers connected to the Internet using the new Windows OS. The figures are from a company called Net Applications, which collects its data from the browsers of visitors to its network of 40,000+ Web sites."

zdude255 writes "Wired is running an article exploring several studies of giving the human brain 'new input devices.' From seeing with your sense of touch to entirely new senses such as sensing direction intuitively, the human brain seems to be capable of interpreting and using new data on the fly. This offers many applications from pilots being able to sense the plane's orientation to the potential recovery of patients with blindness or ear damage. (which helps balance).'It turns out that the tricky bit isn't the sensing. The world is full of gadgets that detect things humans cannot. The hard part is processing the input. Neuroscientists don't know enough about how the brain interprets data. The science of plugging things directly into the brain -- artificial retinas or cochlear implants -- remains primitive. So here's the solution: Figure out how to change the sensory data you want -- the electromagnetic fields, the ultrasound, the infrared -- into something that the human brain is already wired to accept, like touch or sight.'"

A number of readers clued us to the latest development in the saga of te sale of DoubleClick: Google has thrown its hat into the ring against Microsoft and (reportedly) Yahoo and AOL. Most of the stories quote a Wall Street Journal piece that is only available to subscribers. Google's entry into the bidding may boost the price for the remaining pieces of DoubleClick (parts of the company having already been sold off) to $2 billion, twice what its current owners paid for the whole thing. Some reports speculate that this figure could give Microsoft pause.

Now that the news about Microsoft's Elite has had a chance to set in, there are a few objections being raised by commentators. That 120 gig hard drive (the really expensive one) is going to come pre-loaded with content; all well and good, but the content transfer cable and software is a bit odd. Additionally, there are serious objections being raised over the frustrations of early adopters. Despite the easy dismissal out of hand heard on Major Nelson's Wednesday podcast, it's not as easy for early 360 buyers to roll with the changes. "Current Xbox 360 owners, who can purchase a separate 120-gigabyte hard drive at a cost of $179, appear to be getting a raw deal. Not only are these early adopters stuck with an older model of the console that offers less in the way of high-definition support, but factor in the cost of a current premium Xbox 360 ($399) and the price of the larger hard drive and the figure is close to $600 dollars, far exceeding the Elite's retail price, due to be $479."

Several readers made us aware that Microsoft said today that it sold more than 20 million Windows Vista licenses in the first month after the OS's general debut on January 30. This compares to 17 million licenses of XP sold in the first two months after its release. (Just a coincidence the announcement came out a day after this community's speculation, surely.) Most of the coverage of this story, picked up from Reuters, looks like it follows an MS press release. The Associated Press dug deeper, noting that since XP's release the overall PC market has grown by almost a factor of 2, so it would be a surprise if Vista didn't do twice as well: "...51 million PCs were sold to consumers worldwide in 2002; this year... 96 million consumers will buy a computer." Also, Microsoft's 20 million figure includes the backlog of upgrade coupons bundled with XP computers sold since last October.

An anonymous reader sends in a story from Central Connecticut State University, claiming that a Prius takes more energy to manufacture than a Hummer — 50% more. In addition, the article claims that the Prius costs $3.25 per mile over its expected lifespan of 100,000 miles compared to $1.95 per mile for the Hummer. The article gets its data from a study by CNW Marketing called Dust to Dust, which is an attempt to account for all the costs of vehicles, from manufacture through operation through repair and disposal. The $3.25/mile cost quoted for the Prius is the 2005 number; for 2006 it is $2.87. This improvement pulled the Prius below the straight industry average — all the other hybrids are still above that average. And the Hummer is not listed at all for 2006. Update: 03/21 00:44 GMT by J : You might want to take those figures with a grain of salt; I don't think anyone's seen the supporting data. Read on for details.

J adds:

The Prius's mediocre cost-per-mile is due mainly to CNW Research assigning the car a short expected lifetime: 109,000 miles. Nobody knows where this number comes from because CNW has not published details about its derivation. If a car will not last very long, then of course its energy cost per mile is high.

Back in July 2006, when CNW's study "Dust to Dust" had just been published (and which remains, unchanged, the original source for today's news), I emailed its president, Art Spinella:

Hello,

I'm with the tech news and discussion site Slashdot.org. One of our readers submitted a story about your Dust to Dust study.

According to Wikipedia, the Prius comes with a 150,000 mile warranty in California and a few other states; 100,000 elsewhere.

On p. 21 and p. 40 of your report I see that you estimate the average Prius will be "removed from the streets... and sent for disposal" at 109,000 miles. Can you explain how you arrived at this figure?

Thank you.

I did not receive a reply.

My question was about the cost-per-mile denominator; here's another critique questioning the numerator.

Mozzarella writes "Could our ISPs be selling our click data without us even knowing it? It seems like the practice is happening a lot more than we realize, and can be tracked for each user. Complete Incorporated's CTO David Cancel told Ars Technica that his company (an internet research firm) licenses click information from ISPs for 'millions of dollars' to figure out how we use the web. From the article: 'He did not give a specific figure about what this broke down to in terms of dollars per ISP user, although someone in the audience estimated that it was in the range of 40 per user per month — this estimate was erroneously attributed to Cancel himself in some reports on the event. Cancel said that this clickstream data is 'much more comprehensive' than data that is normally gleaned through analyzing search queries.'"
