How Climate Scientists Parallel Early Atomic Scientists 440

Posted by Soulskill from the politicians-see-them-as-tools-to-be-used dept.
Lasrick writes "Kennette Benedict writes in the Bulletin of the Atomic Scientists about the existential threat of climate change, and how the scientists who study and write about it are similar to the early atomic scientists who created, and then worried about, the threat that nuclear weapons posed to humanity: 'Just as the Manhattan Project participants could foresee the coming arms race, climate scientists today understand the consequences of deploying the technologies that defined the industrial age. They also know that action now to reduce greenhouse gas emissions will mitigate the worst consequences of climate change, just as the Manhattan Project scientists knew that early action to forestall a deadly arms race could prevent nuclear catastrophe.'"

"Dramatic Decline" Warning For Plants and Animals 696

Posted by samzenpus from the it's-getting-hot-in-here dept.
An anonymous reader writes "Worldwide levels of the chief greenhouse gas that causes global warming have hit a milestone, reaching an amount never before encountered by humans, federal scientists said. Carbon dioxide was measured at 400 parts per million at the oldest monitoring station in Hawaii, which sets the global benchmark. More than half of plants and a third of animal species are likely to see their living space halved by 2080 if current trends continue."

Global Temperatures Are Close To 11,000-Year Peak 416

Posted by Soulskill from the but-it-was-cold-yesterday dept.
ananyo writes "Global average temperatures are now higher than they have been for about 75% of the past 11,300 years, a study published in Science suggests. Researchers have reconstructed global climate trends all the way back to when the Northern Hemisphere was emerging from the most recent ice age. They looked at 73 overlapping temperature records including sediment cores drilled from lake bottoms and sea floors around the world, and ice cores collected in Antarctica and Greenland. For some records, the researchers inferred past temperatures from the ratio of magnesium and calcium ions in the shells of microscopic creatures that had died and dropped to the ocean floor; for others, they measured the lengths of long-chain organic molecules called alkenones that were trapped in the sediments. From the first decade of the twentieth century to now, global average temperatures rose from near their coldest point since the ice age to nearly their warmest, they report (abstract)."

West Antarctica Warming Faster Than Thought 247

Posted by timothy from the it's-just-preheating-for-now dept.
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

Posted by samzenpus from the logical-ruling dept.
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

Posted by samzenpus from the factor-your-future dept.
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

Posted by timothy from the erasing-the-analog-hole dept.
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

Posted by samzenpus from the two-pound-hammer-and-ten-penny-nail dept.
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

Posted by CmdrTaco from the i'd-use-one-of-those dept.
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

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.'"
