Artificial Gecko Adhesive, Now In Experimental Glue 102

thefickler writes "Scientists at the University of Dayton have created a peel-on, peel-off glue which mimics the wall-climbing abilities of Spiderman. The substance, based on the feet of the Gecko lizard, is three times stickier than existing adhesives. The material is so strong that a 4×4mm pad would be enough to hold a 1.5kg object such as a hardcover book. However, it's likely too expensive for consumer use: one British scientist calculates that a single Post-it note using the glue would cost around a thousand dollars." We've mentioned the possibilities of synthetic gecko technology several times before, including as applied in this wall-climbing robot; commercial applications have seemed just around the corner for a while now.

Google Browser Sync To Be Discontinued 195

Dude With An Afro writes "What could have been a great Google project is now history. For those who never used it, Google Browser Sync was a Firefox extension that synchronized your bookmarks, web history, browser sessions and passwords across multiple computers by temporarily saving them to Google's servers. According to the Google Browser Sync team: 'It was a tough call, but we decided to phase out support for Browser Sync. Since the team has moved on to other projects that are keeping them busy, we don't have time to update the extension to work with Firefox 3 or to continue to maintain it.' For all of those who fell in love with Google's Browser Sync, our only hope now is to resort to poorly maintained 3rd party extensions without Google's blessing." While it was undoubtedly a useful utility, the argument can also be made that it wasn't the most secure extension in the world, what with having your personal data kept on Google's servers and shot around the internet.

Toddlers May Learn Language By Data Mining 213

Ponca City, We Love You writes "Toddlers' brains can effortlessly do what the most powerful computers with the most sophisticated software cannot: learn language simply by hearing it used. A ground-breaking new theory postulates that young children are able to learn large groups of words rapidly by data-mining. Researchers Linda Smith and Chen Yu attempted to teach 28 children, 12 to 14 months old, six words by showing them two objects at a time on a computer monitor while two pre-recorded words were read to them. No information was given regarding which word went with which image. After viewing various combinations of words and images, however, the children were surprisingly successful at figuring out which word went with which picture. Yu and Smith say it's possible that the more words tots hear, and the more information available for any individual word, the better their brains can begin simultaneously ruling out and putting together word-object pairings, thus learning what's what. Yu says if they can identify key factors involved in this form of learning and how it can be manipulated, they might be able to make learning languages easier for children and adults. Understanding children's learning mechanisms could also further machine learning."

Email In the 18th Century 279

morphovar forwards a writeup in Low-tech Magazine recounting an almost-forgotten predecessor to email and packet-switched messaging: the optical telegraph. The article maps out some of the European networks but provides no details of those built in North America in the early 1800s. Man-in-the-middle attacks were dead easy. "More than 200 years ago it was already possible to send messages throughout Europe and America at the speed of an airplane — wireless and without need for electricity. The optical telegraph network consisted of a chain of towers ... placed 5 to 20 kilometers apart from each other. Every tower had a telegrapher, looking through a telescope at the previous tower in the chain. If the semaphore on that tower was put into a certain position, the telegrapher copied that symbol on his own tower. A message could be transmitted from Amsterdam to Venice in one hour's time. A few years before, a messenger on a horse would have needed at least a month's time to do the same."
