+ - Australia repeals carbon tax->

Submitted by schwit1
schwit1 (797399) writes "After almost a decade of heated political debate, Australia has become the world's first developed nation to repeal carbon laws that put a price on greenhouse gas emissions.

In a vote that could highlight the difficulty in implementing additional measures to reduce carbon emissions ahead of global climate talks next year in Paris, Australia's Senate on Wednesday voted 39-32 to repeal a politically divisive carbon emissions price that contributed to the fall from power of three Australian leaders since it was first suggested in 2007.

Australia, the world's 12th largest economy, is one of the world's largest per capita greenhouse gas emitters due to its reliance on coal-burning power stations to power homes and industry. In 2011, daily emissions per head amounted to 49.3 kilograms (108 pounds), almost four times higher than the global average of 12.8 kilograms, and slightly ahead of the U.S. figure of 48.2 kilograms."

Submitted by sciencehabit
sciencehabit (1205606) writes "The world’s largest laser, a machine that appeared as the warp core in "Star Trek into Darkness", has attained a powerful result: It's squeezed diamond, the least compressible substance known, 50 million times harder than Earth's atmosphere presses down on us. The finding should help scientists better understand how material behaves at the great pressures that prevail deep inside giant planets."

+ - The hacking of NASDAQ->

Submitted by puddingebola
puddingebola (2036796) writes "Businessweek has an account of the 2010 hacking of the NASDAQ exchange. From the article, "Intelligence and law enforcement agencies, under pressure to decipher a complex hack, struggled to provide an even moderately clear picture to policymakers. After months of work, there were still basic disagreements in different parts of government over who was behind the incident and why. “We’ve seen a nation-state gain access to at least one of our stock exchanges, I’ll put it that way, and it’s not crystal clear what their final objective is,” says House Intelligence Committee Chairman Mike Rogers, a Republican from Michigan, who agreed to talk about the incident only in general terms because the details remain classified. “The bad news of that equation is, I’m not sure you will really know until that final trigger is pulled. And you never want to get to that.”""

+ - Cosmologists Prove Negative Mass Can Exist In Our Universe

Submitted by KentuckyFC
KentuckyFC (1144503) writes "The idea of negative mass has fascinated scientists since it was first used in the 16th century to explain why metals gain weight when they are oxidised. Since then, theoretical physicists have shown how it could be used to create exotic objects such as wormholes and the Alcubierre warp drive. But cosmologists' attempts to include negative matter in any reasonable model of the cosmos have always run into trouble because negative mass violates the energy conditions required to make realistic universes with Einstein's theory of general relativity. Now a pair of cosmologists have round a way round this. By treating negative mass as a perfect fluid rather than a solid point-like object, they've shown that negative mass does not violate the energy conditions as had been thought and so must be allowed in our universe. That has important consequences. If positive and negative mass particles were created in the early universe, they would form a kind of plasma that absorbs gravitational waves. Having built a number of gravitational wave observatories that have to see a single gravitational wave, astronomers might soon need to explain the absence of observations. Negative mass would then come in extremely handy."

+ - Nearly 25 years ago, IBM helped save Macintosh->

Submitted by dcblogs
dcblogs (1096431) writes "Apple and IBM, which just announced partnership to bring iOS and cloud services to enterprises, have helped each other before. IBM played a key role in turning the Macintosh into a successful hardware platform at a point when it — and the company itself — were struggling. Nearly 25 years ago, IBM was a part of an alliance that gave Apple access to PowerPC chips for Macintosh systems that were competitive, if not better performing in some benchmarks, than the processors Intel was producing at the time for Windows PCs. In 1991, Apple was looking for a RISC-based processor to replace the Motorola 68K it had been using in its Macintosh line. "The PCs of the era were definitely outperforming the Macintoshes that were based on the 68K," he said. "Apple was definitely behind the power, performance curve," said Nathan Brookwood, principal analyst at Insight 64. The PowerPC processor that emerged from that earlier pairing changed that. PowerPC processors were used in Macintoshes for more than a decade, until 2006, when Apple switched to Intel chips."

+ - Fossils of Cambrian predator preserved with brain impressions

Submitted by Anonymous Coward
An anonymous reader writes "Researchers on Wednesday described fossilized remains unearthed in China showing in fine detail the brain structures of a bizarre group of sea creatures that were the top predators more than half a billion years ago. The 520-million-year-old creature, one of the first predators of its day, sported compound eyes, body armor and two spiky claws for grabbing prey. "The animals of the Cambrian are noted for being a collection of oddballs that are sometimes difficult to match up with anything currently living on Earth. But even among these oddities, Anomalocarids stand out (as their name implies). The creatures propelled themselves with a series of oar-like paddles arranged on their flanks, spotted prey with enormous compound eyes, and shoveled them into a disk-like mouth with large arms that resided at the very front of their bodies—although some of them ended up as filter feeders.""

+ - Japan arrests woman for making a printable 3d model of her vagina

Submitted by antifoidulus
antifoidulus (807088) writes "The BBC is reporting that a Japanese woman has been arrested for making a 3d model of her vagina that can be printed using a 3d printer. Megumi Igarashi had sent the printable model to people who sent her money to create it. A police spokesman told AFP news agency she had distributed data that could "create an obscene shape". While giant phalluses are a common spectacle at Japanese fertility festivals, apparently vaginas are still considered "taboo". Ms. Igarashi is fighting the charges."

While money doesn't buy love, it puts you in a great bargaining position.
