An anonymous reader quotes a report from Bloomberg: In a farm deep in the southern region of China lives a very big pig that's as heavy as a polar bear. The 500 kilogram, or 1,102 pound, animal is part of a herd that's being bred to become giant swine. At slaughter, some of the pigs can sell for more than 10,000 yuan ($1,399), over three times higher than the average monthly disposable income in Nanning, the capital of Guangxi province where Pang Cong, the farm's owner, lives. While Pang's pigs may be an extreme example of the lengths farmers are going to fill China's swelling pork shortage problem, the idea that bigger is better has been spreading across the country, home to the world's most voracious consumers of the meat.

High pork prices in the northeastern province of Jilin is prompting farmers to raise pigs to reach an average weight of 175 kilograms to 200 kilograms, higher than the normal weight of 125 kilograms. They want to raise them "as big as possible,"said Zhao Hailin, a hog farmer in the region. The trend isn't limited to small farms either. Major protein producers in China, including Wens Foodstuffs Group Co, the country's top pig breeder, Cofco Meat Holdings Ltd. and Beijing Dabeinong Technology Group Co. say they are trying to increase the average weight of their pigs. Big farms are focusing on boosting the heft by at least 14%, said Lin Guofa, a senior analyst with consulting firm Bric Agriculture Group. The average weight of pigs at slaughter at some large-scale farms has climbed to as much as 140 kilograms, compared with about 110 kilograms normally, Lin said. That could boost profits by more than 30%, he said.

Sonny Yatsen writes "NPR's Robert Krulwich explores the work of several designers who are working on carnivorous furniture. These creations, include a clock that feeds on dead flies, and a table that lures mice into a guillotined death. 'We want robots to be able to get their own energy from the environment,' says co-designer Prof. Melhuish. Let's hope they come up with a lounge chair that eats cockroaches sometime soon."

An anonymous reader writes "The oil leak in the Gulf of Mexico could be stopped with an underground nuclear blast, a Russian newspaper reports. Komsomoloskaya Pravda, the best-selling Russian daily, reports that in Soviet times such leaks were plugged with controlled nuclear blasts underground. The idea is simple, KP writes: 'The underground explosion moves the rock, presses on it, and, in essence, squeezes the well's channel.' It's so simple, in fact, that the Soviet Union used this method five times to deal with petrocalamities, and it only didn't work once."

ByronScott writes "A team of researchers at MIT has just announced that they have successfully modified a virus to split apart molecules of water, paving the way for an efficient and non-energy-intensive method of producing hydrogen fuel. 'The team, led by Angela Belcher, the Germeshausen Professor of Materials Science and Engineering and Biological Engineering, engineered a common, harmless bacterial virus called M13 so that it would attract and bind with molecules of a catalyst (the team used iridium oxide) and a biological pigment (zinc porphyrins). The viruses became wire-like devices that could very efficiently split the oxygen from water molecules. Over time, however, the virus-wires would clump together and lose their effectiveness, so the researchers added an extra step: encapsulating them in a microgel matrix, so they maintained their uniform arrangement and kept their stability and efficiency.'"

Zordak writes "CNN has up a story about several Israeli firms that want to replace metal detectors at airports with biometric readings. For example, with funding from TSA and DHS, 'WeCU ([creepily] pronounced "We See You") Technologies, employs a combination of infra-red technology, remote sensors and imagers, and flashing of subliminal images, such as a photo of Osama bin Laden. Developers say the combination of these technologies can detect a person's reaction to certain stimuli by reading body temperature, heart rate and respiration — signals a terrorist unwittingly emits before he plans to commit an attack.' Sensors may be embedded in the carpet, seats, and check-in screens. The stated goal is to read a passenger's 'intention' in a manner that is 'more fair, more effective and less expensive' than traditional profiling. But not to worry! WeCU's CEO says, 'We don't want you to feel that you are being interrogated.' And you may get through security in 20 to 30 seconds."

ColGraff points out reporting at Science News about the possibility of killing bacteria with paint. Scientists in the UK have found that high concentrations of titanium oxide nanoparticles in paint can kill bacteria by creating hydroxyl radicals when exposed to ordinary fluorescent light. Titanium dioxide is present in most white paint at concentrations of 30% or so, but not always at nanoparticle scale. The researchers found that an 80% concentration of TiO2 nanoparticles worked well to kill E. Coli bacteria. There is hope that the technique could be used against "superbugs," which are resistant to multiple antibiotics. A researcher not associated with the UK team pointed out the problem with developing products based on this idea: "[A]nything that survives and sticks around grows greater resistance... ultimately [antibiotic paint] will be its own worst enemy and the bacteria could grow to be even stronger."
