Teenager Invents Cheap Solar Panel From Human Hair 366 Screenshot-sm

Posted by samzenpus
from the 50-watt-shampoo dept.
Renoise writes "Milan Karki, 18, who comes from a village in rural Nepal, believes he has found the solution to the developing world's energy needs. A solar panel made from human hair. The hair replaces silicon, a pricey component typically used in solar panels, and means the panels can be produced at a low cost for those with no access to power. The solar panel, which produces 9 volts (18 watts) of energy, costs around $38 US (£23) to make from raw materials. Gentlemen, start your beards. The future of hair farming is here!"

Irish Astronomers Investigate Sky Explosion 157

from the stopping-snake-attacks-since-400-AD dept.
puroresu writes "Astronomers in Ireland have appealed to the public to contact them with eyewitness accounts of a massive explosion in the sky over the country. From the BBC: 'Astronomy Ireland chairman David Moore said: "So far, reports have been registered by residents in west Cork, Kerry, Cavan and as far north as Donegal, thus suggesting that this spectacular event may have been witnessed by people all over the country. In the past two decades there have been two major explosions in the skies over Ireland. When we investigated these, we were able to conclude that one was a Russian military satellite that exploded over the country, and the other was a rock from space."'"

Running Old Desktops Headless? 347

Posted by Soulskill
from the must-be-the-new-chicken-os dept.
CajunArson writes "I recently dug up an old P4 that is in fine working order and did what any self-respecting Slashdotter would do: I slapped Linux on it to experiment with making an NFSv4 server. One other thing I did was to remove the old AGP video card to save on power, since this is a headless machine. Now, I removed the video card after the installation, and I'm doing just fine as long as the machine will boot to a state where networking works and I can SSH to it. My question: Is there a good solution to allow me to log into this box if it cannot get on the network? I'm looking for solutions other than slapping a video card back in. In my case, I will have physical access to the machine. A few caveats to make it interesting: This question is for plain old desktop/laptop systems, not network servers designed to run headless. Also, I am aware of the serial console, but even 'old' machines may only have USB, and I have not seen any good documentation on how and whether USB works as a substitute. Finally, if there is any way to access the BIOS settings without needing a video card, that would be an extra bonus, but I'm satisfied with just local OS access starting from the GRUB prompt."

Avatar, Has Sci-fi Found Its Heaven's Gate? 443

from the wilburies-playing-end-of-the-line dept.
brumgrunt writes "Den Of Geek wonders if James Cameron's Avatar is heading for a fall, and if it will even be a science fiction film, off the back of the previews shown last week. It writes: 'It seems in Avatar that all this gee-whiz science is merely there to draw the "old crowd" in and provide some kind of rationale for a brightly-coloured fantasy-world which reflects the most emetic of the artwork plastered over teenage girls' MySpace pages.'"

Apple vs. Google, Who Will Control the iPhone? 213

Posted by CmdrTaco
from the that's-a-good-question dept.
Pieroxy writes "Theiphoneblog carries a nice article on the reason Apple rejected the Google Voice application even though it doesn't violate any terms and services. The article goes in depth over the issue of controlling the hardware (Apple) vs. controlling the software (Google & Apple so far) and how Apple doesn't want Google to take over a critical part of its phone. Just like Google is going into the OS business to make sure it never gets cut out, Apple is also building a huge data center to — they guess — take over some online cloud computing business of their own and be less dependent on Google for these services."

P.I.I. In the Sky 222

Posted by Soulskill
from the not-about-pie-or-pi dept.
Frequent Slashdot contributor Bennett Haselton writes "A judge rules that IP addresses are not 'personally identifiable information' (PII) because they identify computers, not people. That's absurd, but in truth there is no standard definition of PII in the industry anyway, because you don't need one in order to write secure software. Here's a definition of 'PII' that the judge could have adopted instead, to reach the same conclusion by less specious reasoning." Hit the link below to read the rest of his thoughts.

DNA Differences Observed Between Blood and Organs 85

Posted by kdawson
from the same-old-same-old dept.
Scrameustache writes "Researcher working on a rare type of aortic abnormality found that the DNA from diseased tissue did not match the DNA from the blood of the same patients So far it's unclear whether these differences in the blood and aortic tissue are the consequence of RNA editing, which changes the messenger RNA but not the gene, or DNA editing, which involves differences in the gene itself. Based on the evidence so far, the researchers believe the differences resulted from developmental rather than somatic DNA alterations. 'Traditionally when we have looked for genetic risk factors for, say, heart disease, we have assumed that the blood will tell us what's happening in the tissue,' lead author Bruce Gottlieb said in a statement. 'It now seems this is simply not the case.'"

Australian Website Bans ... Australians 247

from the only-ones-who-could-in-a-place-like-this dept.
Nazlfrag writes "Earlier this month the blog and discussion forum ZGeek was sued for $42 million AUD over a user's comment. The plaintiffs are aspiring movie producers who claim to have lost a movie deal due to a 9/11 conspiracy discussion thread. Even though the initial lawsuit has been thrown out, and the company complied with lawyers' demands by taking down the offending posts, it is believed the plaintiffs will file suit again. In addition to suing the forum, in an Australian first they have been granted an injunction to force the ISPs to disclose the IP addresses of the two posters involved. Due to the risk of incurring even greater legal costs the company is closing its doors in Australia, and will ban their fellow countrymen from posting there again."

bfire writes to tell us that marketing firm uSocial has decided to apply a new monetization scheme to the Twitter service by providing packages of followers for purchase. "According to the firm, a single Twitter follower could be worth $0.10 a month. It is selling followers in various packages, starting at 1,000 for $87, which is delivered in seven days, and going all the way up to 100,000 followers at a cost of $3,479, delivered over a year." This is just the latest in a number of different exploits and problems of the Twitter universe as individuals try to subvert a popular tool into a self-serving device.

US ISPs Using Push Polling To Stop Cheap Internet 417

Posted by kdawson
from the we-don't-want-your-kind-here dept.
An anonymous reader writes "What happens when a new ISP is started somewhere in the United States that completely blows out of the water all the other ISPs in the area, in terms of price and performance? Apparently, that question is being answered in North Carolina, where Greenlight Inc., a company started by a city government, is trying to offer faster, more reliable, and cheaper Internet service to the local residents. Time Warner and Embarq can't compete. So they are not only lobbying the state government to destroy the upstart competition, but are now using push polling methods to gain support, across the two cities that could benefit from the new ISP, for the 'Level the playing field' legislation they got introduced in the legislature." A local news outlet provides coverage more friendly to the incumbents' point of view.

What Features Should Be Included With iPhone 3.0? 606

Posted by ScuttleMonkey
from the not-that-apple-listens-to-consumers dept.
With the announcement coming tomorrow, Macworld has posted their top list of 15 features they would like to see in an iPhone 3.0 update. The list includes some things that people have been asking for since launch (like cut and paste) and things that were once there but have since been silently removed (like push notifications/background apps). With almost 2 years of time to grow and learn, what other things are woefully inadequate on Apple's popular handheld?

US Adults Fail Basic Science Literacy 1038

Posted by kdawson
from the ignorance-can-be-fixed dept.
TaeKwonDood writes "Do you want the bad news first or the good news? The good news is that about 80% of Americans think science knowledge is 'very important' to our future. The bad news is most of those people think it's up to someone else to get knowledgeable. Only 15% actually know how much of the planet is covered in water (47% if you accept a rough approximation of the exact number) and over 40% think dinosaurs and humans cavorted together like in some sort of 'Land Of The Lost' episode. What to do? Pres. Obama thinks merit pay for teachers makes sense. Yes, it will enrage the teachers' union, but it might inspire better people to go into science teaching. It's either that or accept that almost 50% of Americans won't know how long it takes the earth to go around the sun."
