Aussie Scientists Find Coconut-Carrying Octopus 205

Posted by timothy from the concealed-carry-in-australian-waters dept.
An anonymous reader writes with this excerpt from an AP report: "Australian scientists have discovered an octopus in Indonesia that collects coconut shells for shelter — unusually sophisticated behavior that the researchers believe is the first evidence of tool use in an invertebrate animal. The scientists filmed the veined octopus, Amphioctopus marginatus, selecting halved coconut shells from the sea floor, emptying them out, carrying them under their bodies up to 65 feet (20 meters), and assembling two shells together to make a spherical hiding spot. ... 'I was gobsmacked,' said Finn, a research biologist at the museum who specializes in cephalopods. 'I mean, I've seen a lot of octopuses hiding in shells, but I've never seen one that grabs it up and jogs across the sea floor. I was trying hard not to laugh.'"

From TFA:

John Jay College sophomore Ahmed Elshafaie, 19, who graduated from Long Island City High School, said he avoids math classes.

"I don't want to ruin my GPA," he said. "High school standards were really low."

Maybe what US high schools need is a difficulty multiplier for GPAs. Of course, that would require some sort of national standard that would have somebody crying foul.

Candy Linked To Violence In Study 205

Posted by samzenpus from the gummy-worms-and-steal dept.
T Murphy writes "A study published in the British Journal of Psychiatry links daily consumption of candy at the age of 10 to an increased chance of being convicted of a violent crime by age 34. The researchers theorize the correlation comes from the way candy is given rather than the candy itself. Candy frequently given as a short-term reward can encourage impulsive behavior, which can more likely lead to violence. An alternative explanation offered by the American Dietetic Association is that the candy indicates poor diet, which hinders brain development. The scientists stress they don't imply candy should be removed from a child's diet, although they do recommend moderation. The study controls for teachers' reports of aggression and impulsivity at age 10, the child's gender, and parenting style. The study can be found here, but the full text is behind a paywall."

Making the pilot itself a cliffhanger? Edgy. But this one seems to push all the envelopes, now doesn't it? Main characters that aren't good have not been a staple of the Stargate series, and I'm just not getting into it. They say that people are going to get left behind on this show? Dr. Rush and Sgt.

Prehistoric Gene Reawakened To Battle HIV 360

Posted by kdawson from the learning-from-our-distant-cousins dept.
Linuss points out research published in PLoS Biology that demonstrates the reawakening of latent human cells' ability to manufacture an HIV defense. A group of scientists led by Nitya Venkataraman began with the knowledge that Old World monkeys have a built-in immunity to HIV: a protein that can prevent HIV from entering cell walls and starting an infection. They examined the human genome for any evidence of a latent gene that could manufacture such a protein, and found the capability in a stretch of what has been dismissively termed "junk DNA." "In this work, we reveal that, upon correction of the premature termination codon in theta-defensin pseudogenes, human myeloid cells produce cyclic, antiviral peptides (which we have termed 'retrocyclins'), indicating that the cells retain the intact machinery to make cyclic peptides. Furthermore, we exploited the ability of aminoglycoside antibiotics to read-through the premature termination codon within retrocyclin transcripts to produce functional peptides that are active against HIV-1. Given that the endogenous production of retrocyclins could also be restored in human cervicovaginal tissues, we propose that aminoglycoside-based topical microbicides might be useful in preventing sexual transmission of HIV-1."

RIAA Seeks Web Removal of Courtroom Audio 138

Posted by ScuttleMonkey from the afraid-people-might-see-what-they-are-up-to dept.
suraj.sun writes to tell us that the RIAA has asked a federal judge to order the removal of what they are calling "unauthorized and illegal recordings" by Harvard University's Charles Nesson of pretrial hearings and depositions in a file-sharing lawsuit. "The case concerns former Boston University student Joel Tenenbaum, who Nesson is defending in an RIAA civil lawsuit accusing him of file-sharing copyrighted music. Jury selection is scheduled in three weeks, in what is shaping up to be the RIAA's second of about 30,000 cases against individuals to reach trial. The labels, represented by the RIAA, on Monday cited a series of examples in which they accuse Nesson of violating court orders and privacy laws by posting audio to his blog or to the Berkman site."

We Rent Movies, So Why Not Textbooks? 398

Posted by Soulskill from the or-food dept.
Hugh Pickens writes "Using Netflix as a business model, Osman Rashid and Aayush Phumbhra founded Chegg, shorthand for 'chicken and egg,' to gather books from sellers at the end of a semester and renting — or sometimes selling — them to other students at the start of a new one. Chegg began renting books in 2007, before it owned any, so when an order came in, its employees would surf the Web to find a cheap copy. They would buy the book using Rashid's American Express card and have it shipped to the student. Eventually, Chegg automated the system. 'People thought we were crazy,' Rashid said. Now, as Chegg prepares for its third academic year in the textbook rental business, the business is growing rapidly. Jim Safka, a former chief executive of Match.com and Ask.com who was recently recruited to run Chegg, said the company's revenue in 2008 was more than $10 million, and this year, Chegg surpassed that in January alone."

The Great Ethanol Scam 894

Posted by kdawson from the don't-even-think-about-switch-grass dept.
theodp writes "Over at BusinessWeek, Ed Wallace is creating quite a stir, reporting that not only is ethanol proving to be a dud as a fuel substitute, but there is increasing evidence that it is destroying engines in large numbers. Before lobbyists convince the government to increase the allowable amount of ethanol in fuel to 15%, Wallace suggests it's time to look at ethanol's effect on smog, fuel efficiency, global warming emissions, and food prices. Wallace concedes there will be some winners if the government moves the ethanol mandate to 15% — auto mechanics, for whom he says it will be the dawn of a new golden age."

CFLs Causing Utility Woes 859

Posted by timothy from the so-very-simple-that-only-a-child-can-do-it dept.
dacut writes "We've seen compact fluorescent lamps start to take over shelf space at the local hardware store. Replacing a 60 watt incandescent with a 13 watt CFL seems like a great savings, though many consumers are disappointed with the slow warm-up times, lower-than-advertised lifetimes, and hassles of disposing the mercury-containing bulbs. Now EDN reports they may use more energy than claimed due to their poor power factor. Mike Grather, of Lumenaire Testing Laboratory, 'checked the power factor for the CFLs and found they ranged from .45 to .50. Their "real" load was about twice that implied by their wattage.' The good news: you're only billed for the 13 watts of real power used. The bad news: the utilities have to generate the equivalent of 28 watts (that is, 28 VA of apparent power for you EEs out there) to light that bulb. Until they fix these issues, I'll hold on to my incandescents and carbon arc lamps, thanks."

Roland Piquepaille Dies 288

Posted by kdawson from the in-memoriam dept.
overheardinpdx writes "I'm sad to report that longtime HPC technology pundit Roland Piquepaille (rpiquepa) died this past Tuesday. Many of you may know of him through his blog, his submissions to Slashdot, and his many years of software visualization work at SGI and Cray Research. I worked with Roland 20 years ago at Cray, where we both wrote tech stories for the company newsletter. With his focus on how new technologies modify our way of life, Roland was really doing Slashdot-type reporting before there was a World Wide Web. Rest in peace, Roland. You will be missed." The notice of Roland's passing was posted on the Cray Research alumni group on Linked-In by Matthias Fouquet-Lapar. There will be a ceremony on Monday Jan. 12, at 10:30 am Paris time, at Père Lachaise.

Anonymous Anger Rampant On the Web 399

Posted by CmdrTaco from the oh-now-this-too dept.
the4thdimension writes "In a story that may bring out the 'duh' in you, CNN has a story about how anonymous anger is rampant on the Internet. Citing various reasons, it attempts to explain why sites like MyBiggestComplaint and Just Rage exist and why anger via the web seems to be everywhere. Various reasons include: anonymity, lack of rules, and lack of immediate consequences. Whatever the reason, they describe that online anger has resulted in real-life violence and suggest methods for parents and teens to cope with e-aggression and to learn to be aware of it." I can't figure out what makes me angrier: my habit of anonymously trolling web forums, or my video game playing.

Behind the Cogent-Sprint Depeering 325

Posted by kdawson from the it's-an-ectomy dept.
An anonymous reader brings an update to Sprint's depeering with Cogent, which we discussed a few days back — namely, Sprint's side of the story. According to them, no free peering contract had ever existed, Cogent refused to pay the bills to exchange traffic, and after a year Sprint gave Cogent 30 days notice of their intent to disconnect. During this 30-day period, when one or two connections (out of ten) per week were shut down, Cogent made no alternate arrangements to alleviate the impact on their customers — but they had a press release ready when Sprint snipped the final wire. It will be interesting to see how Cogent responds.

The United States can't possibly allow this tank of deadly chemicals to hit the ground without testing out its anti-satellite missile system, can it?

I mean, someone could get exposed to ammonia and we can't let THAT happen, even if it would probably just burn up and dissipate anyway.
