Mussel Glue Could Help Repair Birth Defects

sciencehabit writes “When it comes to hanging on tight, the lowly mussel has few rivals in nature. Researchers have sought the secrets behind the bivalve’s steadfast grip on wet, slippery rock. Now, a researcher says he has used the mollusk’s tricks to develop medical applications. These include a biocompatible glue that could one day seal fetal membranes, allowing prenatal surgeons to repair birth defects without triggering dangerous premature labor.” Read more of this story at Slashdot.

Ants Use Sound To Communicate

sciencehabit writes “A new study shows that ant pupae—a stage between larvae and adult—can communicate via sound, and that this communication can be crucial to their survival. The young insects have a specialized spike along their abdomen that they stroke with one of their hind legs, similar to dragging the teeth of a comb along the edge of a table. This noise serves primarily as an emergency beacon, allowing the ants to shout for help when being threatened by a predator.” Read more of this story at Slashdot.

Transparent Transistors Printed On Paper

MTorrice writes “To make light-weight, inexpensive electronics using renewable materials, scientists have turned to a technology that is almost 2,000 years old: paper. Researchers fabricated organic transistors on a transparent, exceptionally smooth type of paper called nanopaper. This material has cellulose fibers that are only 10 nm in diameter. The nanopaper transistors are about 84% transparent, and their performance decreases only slightly when bent.” Read more of this story at Slashdot.

Glasses That Hack Around Colorblindness

MatthewVD writes “In 2006, researcher Mark Changizi came up with a novel theory for why humans evolved with color vision: to detect social cues and emotions in others. He built glasses called 02Amps to enhance perception of blood pooling. Some hospitals have tried using the glasses to see bruising that’s not visible unaided, or help nurses find veins. But it turns out now that the glasses might be able to fix some forms of colorblindness, too.” Read more of this story at Slashdot.

Replicating Hardest Known Biomaterial Could Improve Solar Cells and Batteries

cylonlover writes “Inspired by the tough teeth of a marine snail and the remarkable process by which they form, assistant professor David Kisailus at the University of California, Riverside is working toward building cheaper, more efficient nanomaterials. By achieving greater control over the low-temperature growth of nanocrystals (abstract), his research could improve the performance of solar cells and lithium-ion batteries, lead to higher-performance materials for car and airplane frames, and help develop abrasion-resistant materials that could be used for anything from specialized clothing to dental drills.” Read more of this story at Slashdot.

The Upcycling Filabot Turns Regular Plastic Scrap Into 3D Printer Filament

A fascinating project is making the rounds this weekend that could change the way we think of 3D printers. The Filabot is a robot that can turn scrap plastic into 3D printer filament, thereby allowing an almost endless supply of material for prototyping and manufacturing. While it’s probably not that exciting for non-hobbyists, the Filabot is essentially a way to make the raw materials used in products like Makerbot out of stuff you’d throw away. The creator, Tyler McNaney, ran a Kickstarter campaign last year and he is slowly but surely bringing the devices to market this year. Obviously you’re going to run into problems with such a small system – the impurities in the plastic and bubbles being of primary concern – but at about $50 a spool, PVC isn’t cheap and if you’re printing quite a bit of prototype hardware there’s room for a bit of error. Kickstarter backers paid $350 for their Filabots and a “public” price isn’t yet set. While there are problems with any recycling technology, the Filabot is a fascinating study at the potential for in-home 3D printing. Imagine, for example, printing out repair parts or toys using stuff that you would normally recycle? It’s a wonderful example of technology finally digging us – imperceptibly slowly, I’ll grant you – out of the plastic waste problem.

Telepresence Robot Rundown

DeviceGuru writes “A handful of innovative high-tech startups have recently emerged to create a new market: remote telepresence robots. With one of these robotic Avatars, you can wander around in the remote environment, chatting with coworkers and managers, attending meetings, and solving problems encountered through those interactions. InformationWeek’s Telepresence Robot Smackdown compares five such bots — the MantaroBot TeleMe, VGo Communications VGo, Anybots QB, Suitable Technologies Beam, and Revolve Robotics Kubi — and includes short videos demonstrating each. As the article concludes, ‘bear in mind that what we’re witnessing here is the emergence of a new industry; and if Moore’s Law applies here as it does to so many IT spheres, it won’t be long before these gadgets are inexpensive, commonplace, and far more flexible and intelligent.” Read more of this story at Slashdot.

Drug Allows Deafened Mice to Regrow Inner Ear Hair

sciencehabit writes “All you graying, half-deaf Def Leppard fans, listen up. A drug applied to the ears of mice deafened by noise can restore some hearing in the animals. By blocking a key protein, the drug allows sound-sensing cells that are damaged by noise to regrow. The treatment isn’t anywhere near ready for use in humans, but the advance at least raises the prospect of restoring hearing to some deafened people.” Read more of this story at Slashdot.
