Morphing Metals 121

Posted by samzenpus
from the forge-ahead dept.
aarondubrow writes "Imagine a metal that 'remembers' its original, cold-forged shape, and can return to that shape when exposed to heat or a magnetic pulse. Like magic out of a Harry Potter novel, such a metal could contract on command, or swing back and forth like a pendulum. Believe it or not, such metals already exist. First discovered in 1931, they belong to a class of materials called 'shape memory alloys (SMA),' whose unique atomic make-up allows them to return to their initial form, or alternate between forms through a phase change."

+ - Dubai ends data services for Blackberry customers

Submitted by jggimi
jggimi (1279324) writes "The United Arab Emirates has decided to end data services to its 500,000 users, according to widely publicized reports, such as this one in the New York Times. "The Emirates have been in a long dispute with Research In Motion, the smartphone’s producer, over the BlackBerry’s highly encrypted data system, which offers security to users but makes it more difficult for governments to monitor communications....The monitoring of information is a particularly thorny issue for autocratic regimes in the Persian Gulf worried that the Internet might be used for antigovernment purposes — a concern heightened by the passionate online response in Iran to the 2009 presidential election that helped energize the opposition and led to weeks of unrest.""

First Self-Replicating Creature Spawned In Conway's Game of Life 241

Posted by Soulskill
from the emergent-gameplay dept.
Calopteryx writes "New Scientist has a story on a self-replicating entity which inhabits the mathematical universe known as the Game of Life. 'Dubbed Gemini, [Andrew Wade's] creature is made of two sets of identical structures, which sit at either end of the instruction tape. Each is a fraction of the size of the tape's length but, made up of two constructor arms and one "destructor," play a key role. Gemini's initial state contains three of these structures, plus a fourth that is incomplete. As the simulation progresses the incomplete structure begins to grow, while the structure at the start of the tape is demolished. The original Gemini continues to disassemble as the new one emerges, until after nearly 34 million generations, new life is born.'"

crimeandpunishment (1754306) writes "The trend of households with a cell phone but no landline continues to grow. New data out today shows one in four American homes are cell phone only. The growing percentage is having a widespread ripple effect....including 911 service, and how polling companies gather data. The trend is led by the young and the poor. More than a third of those under 35, or below the poverty level, have only cell phones."

Submitted by ByronScott
ByronScott (1646747) writes "Assistant architecture professor Ginger Krieg Dosier recently unveiled a new breed of biologically “grown” bricks that are durable, sustainably manufactured, and easily produced from readily available materials. Called “Better Bricks,” the building material can be “grown” from sand, common bacteria, calcium chloride, and urea (yes, the stuff in your pee) instead of being baked, which consumes a ton of energy."

+ - Adobe demoes Flash running on Android

Submitted by recoiledsnake
recoiledsnake (879048) writes "Adobe Evangelist Ryan Stewart has posted a video on Youtube that showcases a preview version of Flash running smoothly on an Android Nexus One on a variety of sampled sites on the Web. Streaming video of TV shows is demoed on the CBS and NHL web sites and a couple of games are shown running with the touch features working nicely. All the web pages and Flash content demoed are normal desktop oriented web pages and weren't optimized for mobiles. Coming on the heels of Android sales overtaking the iPhone and a possible anti-trust enquiry against Apple, will iPad and iPhone users that want Flash be able to opt-in for a Flash player App? Or will all iPhone OS users be denied access to ubiquitous Flash content and video on the Web due to Jobs' whims? This may accelerate sales of Android phones(and future tablets) even further."

Woman Creates 3-D Erotic Book For the Blind 113

from the is-that-a-book-in-your-pocket-or-are-you-just-happy-to-see-me dept.
Lisa J. Murphy has written an erotic book with tactile images for that special visually impaired porn connoisseur in your life. Tactile Mind contains explicit softcore raised images, along with Braille text and photos. From the article: "A photographer with a certificate in Tactile Graphics from the Canadian National Institute for the Blind, Murphy learned to create touchable images of animals for books for visually impaired children. Then she realized that there was a lack of such books for adults only. 'There are no books of tactile pictures of nudes for adults, at least the last time I looked around,' says Murphy. 'We're breaking new ground. Playboy has [an edition with] Braille wording, but there are no pictures.' She says that while we live in a culture saturated with sexual images, the blind have been 'left out.'"
