Submission + - New Headphones Generate Sound With Carbon Nanotubes (acs.org)

MTorrice writes: A new type of headphone heats up carbon nanotubes to crank out tunes. The tiny speaker doesn’t rely on moving parts and instead produces sound through the thermoacoustic effect. When an alternating current passes through the nanotubes, the material heats and cools the air around it; as the air warms, it expands, and as it cools, it contracts. This expansion and contraction creates sound waves. The new nanotube speaker could be manufactured at low cost in the same facilities used to make computer chips, the researchers say.

Submission + - Engineers invent programming language to build synthetic DNA (washington.edu)

vinces99 writes: Similar to using Python or Java to write code for a computer, chemists soon could be able to use a structured set of instructions to “program” how DNA molecules interact in a test tube or cell. A team led by the University of Washington has developed a programming language for chemistry that it hopes will streamline efforts to design a network that can guide the behavior of chemical-reaction mixtures in the same way that embedded electronic controllers guide cars, robots and other devices. In medicine, such networks could serve as “smart” drug deliverers or disease detectors at the cellular level.

Submission + - Sinkhole Sucks Brains From Wasteful Bitcoing-Mining Botnet (techweekeurope.co.uk) 1

judgecorp writes: A sinkhole has taken a quarter of the bots out of the ZeroAcess botnet which was making money for its operators through click fraud and Bitcoin mining. This particular Bitcoin mining operation was only profitable through the use of stolen electricity — according to Symantec, which operated the sinkhole, ZeroAccess was using $561,000 of electricity a day on infected PCs, to generate about $2000 worth of Bitcoin/

Submission + - NASA's New FINDER Scans for Victim Vitals Through Disaster Rubble (vice.com)

Daniel_Stuckey writes: NASA now has a new device, called FINDER (Finding Individuals for Disaster and Emergency Response), which could be the next player in hastening the response time in such grim scenarios.

Although dogs have aided emergency responders for decades, a pooch relies on its sniffer in emergency situations. FINDER, on the other hand, uses microwaves in a Doppler-like fashion to sense respiration and pulse. The lightweight briefcase, as displayed in the video above, was developed for the Department of Homeland Security with remote-sensing radar technology NASA's Jet Propulsion Lab uses to locate spacecraft in flight. The unit includes a tablet, on which a hidden person's vitals are then displayed.

Submission + - Fracked Shale Could Sequester Carbon Dioxide (acs.org)

MTorrice writes: The same wells that energy companies drill to extract natural gas from shale formations could become repositories to store large quantities of carbon dioxide. A new computer model suggests that wells in the Marcellus shale, a 600-sq-mile formation in the northeastern U.S. that is a hotbed for gas extraction, could store half the CO2 emitted by the country’s power plants from now until 2030.

Submission + - He Fixed 300,000+ machines - America's Oldest Typewriter Repairman Dies at 96 (nytimes.com)

An anonymous reader writes: The New York Times reports, "For eight decades, Manson Whitlock kept the 20th century’s ambient music going: the ffft of the roller, the ding of the bell, the decisive zhoop ... bang of the carriage return, the companionable clack of the keys. From the early 1930s until shortly before his death last month at 96, Mr. Whitlock, at his shop in New Haven, cared for the instruments, acoustic and electric, on which that music was played. Mr. Whitlock was often described as America’s oldest typewriter repairman. He was inarguably one of the country’s longest-serving. Over time he fixed more than 300,000 machines, tending manuals lovingly, electrics grudgingly and computers never. “I don’t even know what a computer is,” Mr. Whitlock told The Yale Daily News, the student paper, in 2010. “I’ve heard about them a lot, but I don’t own one, and I don’t want one to own me.” " (The music linked to by the Times is Leroy Anderson's classic The Typewriter for orchestra.)

Submission + - Exclusive photos of Amazon's completely redesigned next-gen Kindle Fire HD (bgr.com)

redkemper writes: There really isn’t much mystery remaining as Amazon prepares to unveil its second-generation Kindle Fire HD tablets and its third-generation Kindle Fire slate in the coming weeks. First we published exclusive details about Amazon’s entire 2013 tablet lineup and then we followed up by revealing all of the key specs for the upcoming new Kindle Fire HD tablets as well as the new entry-level Kindle Fire. Amazon’s new high-definition slates are shaping up to be two of the most impressive tablets in the world when they debut, and anticipation is certainly building. Now, BGR has obtained exclusive photos of the unannounced next-generation Kindle Fire HD that Amazon is preparing to unveil as soon as later this month, giving the world its first-ever look at Amazon’s new hardware for 2013...

Submission + - Amazon lists $4.5 million artwork - and gets funny reviews (corporate-ir.net)

An anonymous reader writes: Last month Amazon opened up a fine art site, selling paintings by Claude Monet and Andy Warhol at multi-million dollar prices, including a rare Norman Rockwell for $4.5 million. "They're listed with the same buttons as other Amazon products — like 'Add to Wish List' and 'Add to Cart'," notes one technology site, which reports that the listings have already become the latest target for more funny fake reviews. ("Is shipping extra?" "Not expensive enough...") Amazon seems to appreciate the parodies, having recently acknowledged their own favorite fake reviews. But at least one reviewer notes that selling a painting on a web site is like something Andy Warhol might do himself, joking that if he were around today "He might even buy it!"

Submission + - Computer-designed proteins recognize and bind small molecules (washington.edu)

vinces99 writes: Computer-designed proteins that can recognize and interact with small biological molecules are now a reality. Scientists have succeeded in creating a protein molecule that can be programmed to unite with three different steroids. The achievement could have far wider ranging applications in medicine and other fields, according to the Protein Design Institute at the University of Washington. “This is a major step toward building proteins for use as biosensors or molecular sponges, or in synthetic biology — giving organisms new tools to perform a task,” said one of the lead researchers, Christine E. Tinberg, a UW postdoctoral fellow in biochemistry.

Submission + - Researchers hope to protect against another HIV-like outbreak (washington.edu)

vinces99 writes: Throughout Asia, humans and monkeys live side-by-side in many urban areas. An international research team has been examining transmission of a virus from monkeys to humans in Bangladesh, one of the world’s most densely populated countries.The scientists have found that some people in these urban areas are concurrently infected with multiple strains of simian foamy virus, including recombinant strains — those from more than one source — originally detected in the monkeys. Asian rhesus macaques are very responsive to change, researchers say, and unlike many other species of primates they will continue thriving in human-altered habitats. Simian foamy viruses, which are ubiquitous in nonhuman primates, are retroviruses that exhibit high levels of mutation and recombination – a potentially explosive combination. By analyzing what is happening at the human-primate interface, the researchers hope to protect humans from another deadly outbreak similar to HIV.

Submission + - Genetic convergent evolution: stunning gene similarities among diverse animals

Toe, The writes: It has long been understood that completely different animals can end up with very similar traits (convergent evolution), and even that genes can converge. But a new study shows an unbelievable level of convergence among entire groups of genes. The study shows that animals as diverse as bats and dolphins, which independently developed echolocation, converge in nearly 200 different genomic regions concentrated in several 'hearing genes'. The implications are rather deep, if you think about it, delving into interesting limitations on diversity or insights into the potential of DNA. And perhaps more importantly, this finding goes a long way toward explaining why almost aliens in the universe look surprisingly identical to humans (though still doesn't explain why they all speak English).
