Tiny Tubes May Trumpet End of Bulky Loudspeakers

Nanotube technology could allow for speakers on clothes, windows, screens

(Newser) - You may soon be able to add paper-thin speakers to that flat-panel TV, the Economist reports. Scientists have used ultra-tiny carbon nanotubes to make a transparent film that produces sound identical to a signal-carrying current that passes through it. If the technology can be made commercially viable, you might be...

Our Economic Cure? Innovation

Innovation, and making it more efficient, can turn gray skies blue

(Newser) - Democrats and Republicans do have something in common: Both parties are wrong on how to resuscitate the flat-lining US economy, Michael Mandel argues in BusinessWeek. Tax cuts or increased government spending aren’t the cure. “Innovation is the best—and maybe the only—way the US can get out...

Fungus Drug Zaps Cancer in Study

New drug starves tumors of blood

(Newser) - A powerful new cancer drug has been developed from a fungus discovered by accident, Reuters reports. The drug, called lodamin, is dramatically effective against a range of cancers and works by starving tumors of blood, according to a new study published in the journal Nature Biotechnology. Mice infected with cancer...

Oil-Slurping Nanotechnology Next Front in Fighting Spills

MIT scientists create mesh that keeps water out, can hold 20 times its weight in crude

(Newser) - Cleaning up oil might soon get faster and cheaper, thanks to nanotechnology. Scientists at MIT have crafted a paper-like substance that can absorb up to 20 times its weight, the Economist reports. The mesh of nanowires, each 1/1,000th the diameter of a human hair, feels and looks like paper—...

Berkeley, Stanford Partner with Saudi University

American schools to help develop science and technology graduate school

(Newser) - Berkeley and Stanford University will help choose faculty and develop curricula for a new university in Saudi Arabia, reports the San Jose Mercury News. The graduate-level King Abdullah University of Science and Technology, funded by a $10 billion gift from the king, will focus on fields like petrochemicals and nano-technology...

A.I. Will Match Human Brain in 20 Years

But nanobots in our neurons will make us smarter, too

(Newser) - One engineer and futurist says it’s only a matter of time before machines are as smart as people, and people are part machine, the BBC reports. Ray Kurzweil claims that artificial intelligence will produce human-level smarts and even emotions by 2029. Humans, meanwhile, will inject nanobots into their brains...

Silicon Could Convert Waste Heat Into Power

New nanowires add to chip tech's bag of tricks

(Newser) - Silicon could turn heat into electricity for cheaper than current technologies based on other materials, reports Technology Review. Researchers made nanowires out of silicon so that it would conduct electricity, but not heat. Normal silicon conducts both very well. The specially-made wires, however, convert heat applied at one end to...

Israelis etch entire text on 0.01-square inch surface

(Newser) - Israeli scientists have crammed the entire Hebrew Bible onto a chip that is half the size of a grain of sugar, the AP reports. They used a particle beam to etch it onto the 0.01-square inch surface “like a hammer and chisel," one scientist said. The new...

Radio Thinner Than Hair Invented

Nanotube radio could have widespread applications

(Newser) - A UC Berkeley team has invented the world's smallest radio, composed of a single carbon nanotube 10,000 times thinner than a human hair. The San Francisco Chronicle reports that the device is the first fully functional radio to qualify as a piece of nanotechnology -- inventions no larger than...

Silicon Ink Makes Splash in Solar Cell Industry

New technology could slash production prices drastically

(Newser) - Silicon ink, a new innovation in nanotechnology, may revolutionize the way that solar panels are produced and dramatically cut solar energy costs. The company that makes the ink, Innovalight, will announce today $28 million in new funding from Norwegian corporation Convexa Capital, as well as plans for a 30,000-square-foot...

Physics award goes to discoverers of 'giant magnetoresistance,' key to shrinking computers

(Newser) - Proving physics isn’t just theoretical black-hole gazing, this year’s Nobel Prize went to a discovery that paved the way for radically shrinking the size of computers. Albert Fert and Peter Grunberg won for uncovering “giant magnetoresistance,” the phenomenon that big electrical resistance variances can be produced...

Physicists Float a New Theory of Levitation

Frictionless parts could fly through the air with the greatest of ease

(Newser) - Two Scottish physics professors have published a report on forces of attraction that could be used to make objects levitate, writes the Telegraph. They've engineered a way to reverse the Casimir force, which normally causes elements to stick together. The discovery may lead to frictionless levitating parts in small mechanical...
