West Antarctica Warming Faster Than Thought 247

New submitter dgrobinson writes "NY Times reports that West Antarctica has warmed more over the last half century than was first thought. A paper released Sunday by the journal Nature Geoscience (abstract) found that the temperature at a research station in the middle of West Antarctica has warmed by 4.4 degrees Fahrenheit since 1958. That is roughly twice as much as scientists previously thought and three times the overall rate of global warming, making central West Antarctica one of the fastest-warming regions on earth."

Texas Supreme Court Cites Mr. Spock 345

An anonymous reader writes "We always knew that Spock was wise and would probably make a pretty good judge, so perhaps it's a good thing to see the Texas Supreme Court citing Spock in a recent ruling, noting his wisdom in stating that 'the needs of the many outweigh the needs of the few.'"

How Much Math Do We Really Need? 1153

Pickens writes "G.V. Ramanathan, a professor emeritus of mathematics, statistics and computer science at the University of Illinois at Chicago, writes in the Washington Post that although a lot of effort and money has been spent to make mathematics seem essential, unlike literature, history, politics and music, math has little relevance to everybody's daily life. 'All the mathematics one needs in real life can be learned in early years without much fuss,' writes Ramanathan. 'Most adults have no contact with math at work, nor do they curl up with an algebra book for relaxation.' Ramanathan says that the marketing of math has become similar to the marketing of creams to whiten teeth, gels to grow hair and regimens to build a beautiful body, but even with generous government grants over the past 25 years, countless courses, conferences, and books written on how to teach teachers to teach, where is the evidence that these efforts have helped students? A 2008 review by the Education Department found that the nation is at 'greater risk now' than it was in 1983, and the National Assessment of Educational Progress math scores for 17-year-olds have remained stagnant since the 1980s (PDF). Meanwhile those who do love math and science have been doing very well and our graduate schools are the best in the world. 'As for the rest, there is no obligation to love math any more than grammar, composition, curfew or washing up after dinner. Why create a need to make it palatable to all and spend taxpayers' money on pointless endeavors without demonstrable results or accountability?'"

Is the Line-in Jack On the Verge of Extinction? 411

SlashD0tter writes "Many older sound cards were shipped with line-out, microphone-in, and a line-in jacks. For years I've used such a line-in jack on an old Windows 2000 dinosaur desktop that I bought in 2000 (600 Mhz PIII) to capture the stereo audio signal from an old Technics receiver. I've used this arrangement to recover the audio from a slew of old vinyl LPs and even a few cassettes using some simple audio manipulating software from a small shop in Australia. I've noticed only recently, unfortunately, that all of the four laptops I've bought since then have omitted a line-in jack, forcing me to continue keeping this old desktop on life support. I've looked around for USB sound cards that include a line-in jack, but I haven't been too impressed by the selection. Is the line-in jack doomed to extinction, possibly due to lobbying from vested interests, or are there better thinking-outside-the-box alternatives available?"

Exactly. I don't think there's a single wind-power installation anywhere in the world that is anywhere close to truly self-supporting. They are a great idea but just don't cut it commercially.

Even the Danes - major investors in (and sellers of) the technology haven't been able to make it pay - except by exporting the technology to other countries. That's why they've tried hushing the economic reports about their w-farms; they don't want to scare away customers with the facts.

That's a pity: I always liked the idea of windfarms.

Directed Energy Weapon Downs Mosquitos 428

wisebabo writes "Nathan Myhrvol demonstrated at TED a laser, built from parts scrounged from eBay, capable of shooting down not one but 50 to 100 mosquitos a second. The system is 'so precise that it can specify the species, and even the gender, of the mosquito being targeted.' Currently, for the sake of efficiency, it leaves the males alone because only females are bloodsuckers. Best of all the system could cost as little as $50. Maybe that's too expensive for use in preventing malaria in Africa but I'd buy one in a second!" We ran a story about this last year. It looks like the company has added a bit more polish, and burning mosquito footage to their marketing.

IdeaPad U1, What We Wanted the iPad To Be 401

Xanator writes "With the announcement of the iPad, the Lenovo IdeaPad U1 Hybrid appears to have gone unnoticed, but maybe we ought to pay it more attention. It's a netbook with a removable screen that turns it into a tablet (switching OS from Windows 7 to a tablet OS within 3 seconds), and it appears to offer what many of us wanted from the iPad. Quoting Engadget: 'When docked, the U1 looks and feels like any other laptop, with an Intel CULV processor and a 128GB SSD running Windows 7 Home Premium. You actually wouldn't know there's a slate hiding in there — until you pull it out and watch it switch to Lenovo's Skylight UI, a process that was smooth and quick for us. Lenovo says the goal is for the full switch to occur in under 3 seconds.'"

Aussie Scientists Find Coconut-Carrying Octopus 205

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.'"

Antarctic Ice Is Growing, Not Melting Away, At Davis Station 633

schwit1 writes "A report from The Scientific Committee on Antarctic Research says that Antarctic ice is growing, not melting away. Ice core drilling in the fast ice off Australia's Davis Station in East Antarctica by the Antarctic Climate and Ecosystems Co-Operative Research Centre shows that last year, the ice had a maximum thickness of 1.89m, its densest in 10 years. The average thickness of the ice at Davis since the 1950s is 1.67m. A paper to be published soon by the British Antarctic Survey in the journal Geophysical Research Letters is expected to confirm that over the past 30 years, the area of sea ice around the continent has expanded."

South Carolina Seeking To Outlaw Profanity Screenshot-sm 849

MBGMorden writes "It looks like in an act that defies common sense, a bill has been introduced in the South Carolina State Senate that seeks to outlaw the use of profanity. According to the bill it would become a felony (punishable by a fine up to $5000 or up to 5 years in prison) to 'publish orally or in writing, exhibit, or otherwise make available material containing words, language, or actions of a profane, vulgar, lewd, lascivious, or indecent nature.' I'm not sure if 'in writing' could be applied to the internet, but in any event this is scary stuff."

EEStor Issued a Patent For Its Supercapacitor 603

An anonymous reader sends us to GM-volt.com, an electric vehicle enthusiast blog, for the news that last week EEStor was granted a US patent for their electric-energy storage unit, of which no one outside the company (no one who is talking, anyway) has seen so much as a working prototype. We've discussed the company on a number of occasions. The patent (PDF) is a highly information-rich document that offers remarkable insight into the device. EEStor notes "the present invention provides a unique lightweight electric-energy storage unit that has the capability to store ultrahigh amounts of energy." "The core ingredient is an aluminum coated barium titanate powder immersed in a polyethylene terephthalate plastic matrix. The EESU is composed of 31,353 of these components arranged in parallel. It is said to have a total capacitance of 30.693 F and can hold 52.220 kWh of energy. The device is said to have a weight of 281.56 pound including the box and all hardware. Unlike lithium-ion cells, the technology is said not to degrade with cycling and thus has a functionally unlimited lifetime. It is mentioned the device cannot explode when being charge or impacted and is thus safe for vehicles."

Scientist Patents New Method To Fight Global Warming 492

SUNSTOP writes to tell us that a relatively unknown Maryland scientist has proposed a public patent that he claims could combat global warming. The proposed plan would require massive amounts of water to be sprayed into the air in an effort to bolster the earth's existing air conditioning system. "First, the sprayed droplets would transform to water vapor, a change that absorbs thermal energy near ground level; then the rising vapor would condense into sunlight-reflecting clouds and cooling rain, releasing much of the stored energy into space in the form of infrared radiation. Kenneth Caldeira, a climate scientist for the Carnegie Institution's Department of Global Ecology at Stanford University whose computer simulation of Ace's invention suggests it would significantly cool the planet. The simulated evaporation of about one-half inch of additional water everywhere in the world produced immediate planetary cooling effects that were projected to reach nearly 1 degree Fahrenheit within 20 or 30 years, Caldeira said."

Broadband Access Without the Pork? 412

An anonymous reader writes "Like many consumers nowadays, I find more of my time spent on the internet and various wireless devices (e.g. mobile phone). This has gotten to the point where I basically do not use a landline or cable television anymore, and they are essentially pork on my broadband bill, which further subjects the consumer to all sorts of clandestine fees that aren't disclosed until the first bill arrives and add a non-trivial sum (in my case, nearly 100%) to the monthly rate. However, it seems that all broadband access providers have this stipulation, that an internet customer must first have a basic phone or cable TV service in order to sign on for the internet service. Are there any ISPs that can get around this and still deliver broadband internet service at a competitive rate?"
