3 Drinks a Day Keeps the Doctor Away 470

Nzimmer911 writes "Heavy drinkers outlive non-drinkers according to a 20 years study following 1,824 people. From the article: 'But a new paper in the journal Alcoholism: Clinical and Experimental Research suggests that - for reasons that aren't entirely clear - abstaining from alcohol does actually tend to increase one's risk of dying even when you exclude former drinkers. The most shocking part? Abstainers' mortality rates are higher than those of heavy drinkers.'"

Did Sea Life Arise Twice? 238

eldavojohn writes "Dr. Adam Maloof has found fossils of sea sponges in Australia from 650 million years ago. You might think this is no big deal unless you consider that sea sponges were thought to have arisen 520 million years ago. These fossils predate the oldest hard bodied fossils we have by a hundred million years. Dr. Maloof is now wondering if life might have arisen twice after the first attempt was quashed 635 million years ago: 'Since animals probably did not evolve twice, we are suddenly confronted with the question of how some relative of these reef-dwelling animals survived the Snowball Earth.' So how is it that life survived the Marinoan glaciation? The BBC has a video on the topic and Wikipedia has a time line of the Proterozoic Eon into the Paleozoic Era."

Wireless PCIe To Enable Remote Graphics Cards 181

J. Dzhugashvili writes "If you read Slashdot, odds are you already know about WiGig and the 7Gbps wireless networking it promises. The people at Atheros and Wilocity are now working on an interesting application for the spec: wireless PCI Express. In a nutshell, wPCIe enables a PCI Express switch with local and remote components linked by a 60GHz connection. The first applications, which will start sampling next year, will let you connect your laptop to a base station with all kinds of storage controllers, networking controllers, and yes, an external graphics processor. wPCIe works transparently to the operating system, which only sees additional devices connected over PCI Express. And as icing on the cake, wPCie controllers will let you connect to standard Wi-Fi networks, too."

JavaScript/HTML 5 Gaming? 201

cjcela writes "Lately I've seen some HTML 5/JavaScript games popping up on the web. Most of them lack sound, and are not polished, but little by little this is changing. As an example, check Galactic Plunder. While it is only a single-level proof of concept, it is one of the first arcade non-Flash games that I've found playable. Do you know of other comparable or better pure JavaScript games?"

Prince Says Internet Is Over 450

the_arrow writes "According to the artist currently known as Prince, 'The internet's completely over.' At least that what he says in an interview with the British newspaper Mirror. Quoting Prince: 'The internet's like MTV. At one time MTV was hip and suddenly it became outdated. Anyway, all these computers and digital gadgets are no good. They just fill your head with numbers and that can't be good for you.'"

Here's an interesting article on the life and times of 24-year-old Jordan Kavoosi, who has made a business of plagiarism. His Essay Writing Company employs writers from across the country, and will deliver a paper on any subject for $23 per page. In addition, his company will get it done in 48 hours, and he guarantees at least a B grade or your money back. From the article: "'Sure it's unethical, but it's just a business,' Kavoosi explains. 'I mean, what about strip clubs or porn shops? Those are unethical, and city-approved.'"
Bug

Tracking Down a Single-Bit RAM Error 277

Hanji writes "We have discussed here before the potential effects of and protections against cosmic ray radiation, but for the average computer user, it's an obscure threat that doesn't affect them in any real way. Well, here's a blog post that describes a strange segfault and, after extensive debugging, traces it down to a single bit flip, probably caused by a stray cosmic ray. Lots of helpful descriptions of Linux debugging techniques in this one, and a pretty clear demonstration that this can be a real problem. I know I'm never buying a desktop without ECC RAM ever again!" The author acknowledges that it might not have been a cosmic ray-based error, but the troubleshooting steps are interesting no matter what the cause.

Geologists Might Be Charged For Not Predicting Quake 375

mmmscience writes "In 2009, a series of small earthquakes shook the region of L'Aquila, Italy. Seismologists investigated the tremors, but concluded that there was no direct indication of a big quake on the horizon. Less than a month later, a magnitude 6.3 earthquake killed more than 300 people. Now, the chief prosecutor of L'Aquila is looking to charge the scientists with gross negligent manslaughter for not predicting the quake."
