Heart Drug May Be Effective for Managing Certain Cancers, Study Suggests

ScienceDaily (Dec. 14, 2011) — Researchers at Queen's University have identified a new mechanism that could potentially explain why the body's immune system sometimes fails to eliminate cancer. The new findings shed light on the possible cause of immune resistance in cancer cells, and indicate that nitroglycerin, a relatively safe and low-cost drug used for more than a century to treat angina, may be effective for managing certain cancers.

Cheap electronic skin edges us closer to cyberpunk future

By   posted Dec 15th 2011 6:13AM

Researchers working for the Department of Energy's Berkeley Lab have figured out how to create relatively inexpensive "electronic skin" comprising carbon nanotubes enriched with semiconductors. Their process involves an enriched single walled carbon nanotube (SWNT) solution embedded in a honeycomb pattern of hexagonal holes to make it more flexible and stretchable - it's so limber, they wrapped it around a baseball, as you can see in the photo above. Combined with inkjet printing of electrical contacts, the technology paves the way for making flexible, wearable computers and a host of other cool things that William Gibson and other cyberpunk authors thought of back in the 1980s: smart bandages, flexible solar cells and electronic skin that can sense touch. Bring on the Zeiss eye implants and neural interface jacks!

But because that appetite includes light itself, it's incredibly rare for us to actually see a black hole suck back an interstellar treat. Astronomers using the European Southern Observatory's Very Large Telescope have found just that: a mysterious, giant gas cloud that's rapidly been pulled into the maw of a supermassive black hole. The researchers, led by Reinhard Genzel of the Max-Planck Institute for Extraterrestrial Physics in Germany, discovered the cloud as part of a now 20-year ESO program tasked with tracking stars as they whirl around the supermassive black hole, known as Sgr A*, at the center of our galaxy."

Simply put, it is easier and cheaper to steal rather than develop the legal way. China has consistently denied it has any responsibility for hacking that originated from servers on its soil, but — based on what is known of attacks from China, Russia and other countries — a declassified estimate of the value of the blueprints, chemical formulas and other material stolen from U.S. corporate computers in the last year reached almost $500 billion"

'Green Routing' Can Cut Car Emissions Without Significantly Slowing Travel Time

Channel Master TV review

By   posted Dec 14th 2011 4:00PM

If you prefer your DVR with no strings attached, your choices are pretty limited these days. You can of course roll your own, but admittedly, that isn't for everyone. Channel Master does plan to change that, though, as it's currently accepting pre-orders for its over-the-air DVR with over-the-top features that doesn't require a subscription. The Channel Master TV ($399) should be hitting retailers and homes this week, and since we love DVRs, especially when they're free from commitments, we decided to take it for a spin. Click through to see how it stacks up. 

The Ability to Love Takes Root in Earliest Infancy

ScienceDaily (Dec. 14, 2011) — The ability to trust, love, and resolve conflict with loved ones starts in childhood -- way earlier than you may think. That is one message of a new review of the literature in Current Directions in Psychological Science, a journal published by the Association for Psychological Science. "Your interpersonal experiences with your mother during the first 12 to 18 months of life predict your behavior in romantic relationships 20 years later," says psychologist Jeffry A. Simpson, the author, with University of Minnesota colleagues W. Andrew Collins and Jessica E. Salvatore. "Before you can remember, before you have language to describe it, and in ways you aren't aware of, implicit attitudes get encoded into the mind," about how you'll be treated or how worthy you are of love and affection.

Judge Orders Man To Delete Revenge Blog

nonprofiteer writes"A Minnesota man violated a restraining order obtained by his ex-girlfriend by blogging about her mental health and sexual issues, and sending links to posts on the blog to her family, friends, and co-workers. The judge then extended the restraining order by 50 years, ordered the guy never to write about his ex on the Internet and ordered him to delete the blog he created. Even though there was no evidence that what he had written was false, the judge said the ex-girlfriend's 'right to be free from harassment' outweighed the guy's 'right to free speech.' 'I believe it's rare, if not unprecedented, for a court to order an entire blog deleted,' says technology law professor Eric Goldman."

NASA Developing Comet Harpoon For Sample Return

An anonymous reader writes"NASA appears to have decided that the best way to grab a sample of a rotating comet that is racing through the inner solar system at up to 150,000 miles per hour while spewing chunks of ice, rock and dust may be to avoid the risky business of landing on it. Instead, researchers want to send a spacecraft to rendezvous with a comet, then fire a harpoon to rapidly acquire samples from specific locations with surgical precisionwhile hovering above the target."

Fracking Disclosure Rules Approved In CO

from the quench-your-thirst dept.
ExE122 writes"Colorado has approved new measures taking a tough stance on the disclosure of chemicals used in fracking. The new law is 'requiring companies to disclose the concentrations of chemicals in addition to the chemicals themselves.' Fracking is a controversial method of natural gas extraction that raises concerns about health and safety issues to surrounding communities. This measure is said to be tougher than similar measures passed in Texas earlier this year."

Why Do People Defend Unjust, Inept, and Corrupt Systems?

ScienceDaily (Dec. 12, 2011) — Why do we stick up for a system or institution we live in -- a government, company, or marriage -- even when anyone else can see it is failing miserably? Why do we resist change even when the system is corrupt or unjust? A new article in Current Directions in Psychological Science, a journal published by the Association for Psychological Science, illuminates the conditions under which we're motivated to defend the status quo -- a process called "system justification."

New Vaccine Attacks Breast Cancer in Mice

MIT builds camera that can capture at the speed of light (video)

By   posted Dec 13th 2011 6:33AM

A team from the MIT media lab has created a camera with a "shutter speed" of one trillion exposures per second -- enabling it to record light itself traveling from one point to another. Using a heavily modified Streak Tube (which is normally used to intensify photons into electron streams), the team could snap a single image of a laser as it passed through a soda bottle. In order to create the slow-motion film in the video we've got after the break, the team had to replicate the experiment hundreds of times. The stop-motion footage shows how light bounces through the bottle, collecting inside the opaque cap before dispersing. The revolutionary snapper may have a fast shutter but the long time it takes to process the images have earned it the nickname of the "the world's slowest fastest camera."

New quantum tunneling transistors to make PCs less power-hungry

By   posted Dec 12th 2011 3:03PM

Yes, that awesome new 8-core chip in your PC is the fastest thing on the block, but it's got your utility meter spinning accordingly. Fortunately, researchers from Penn State have come up with a new high performance transistor that may turn future chips from power hogs into current-sipping silicon. The group, in cooperation with semiconductor manufacturer IQE, has created a high-performance transistor capable of significantly reducing power demand whether it's idle or switching. Doctoral candidate Dheeraj Mohata's the one who made it happen by inventing an alternative to traditional MOSFET (metal-oxide semiconductor field-effect transistors) technology capable of turning on and off using far less power. Mohata's method uses a tunneling field effect transistor crafted from dissimilar semiconductor materials to provide instant on-off capability at 300 millivolts -- compared to MOSFET's one volt requirement -- to provide a power savings of 70 percent. You can dig deeper into the technical transistor details at the source, but all you really need to know is that the ladies love a PC with paltry power consumption.

The Mexican Cartel's Hi-Tech Drug Tunnels

Posted by samzenpus  

from the demand-based-technology dept.
In the past 5 years more than 100 drug tunnels between Mexico and the U.S. have been discovered. This is double the number found over the previous 15 years. Not only are they growing in number, but the tunnels are becoming much more sophisticated including electric rail systems, hydraulic elevators, and secret entrances, one opened via a fake water tap. From the article: "When architect Felipe de Jesus Corona built Mexico's most powerful drug lord a 200-foot-long tunnel under the U.S.-Mexican border with a hydraulic lift entrance opened by a fake water tap, the kingpin was impressed. The architect 'made me one f---ing cool tunnel' Joaquin 'Shorty' Guzman said, according to court testimony that helped sentence Corona to 18 years in prison in 2006. Built below a pool table in his lawyer's home, the tunnel was among the first of an increasingly sophisticated drug transport system used by Guzman's Sinaloa cartel. U.S. customs agents seized more than 2,000 pounds of cocaine which had allegedly been smuggled along the underground route."
