Printable bionic ear sends hearing to the dogs

Using off-the-shelf 3D printing tools, silver nanoparticles, and cell culture, scientists at Princeton University have created a functional bionic ear that can detect radio frequencies far beyond the normal human range.

Living, 3D-printed tissue has been in the news a fair bit recently, but this is the first attempt at creating a fully functional organ with embedded electronics.

"In general, there are mechanical and thermal challenges with interfacing electronic materials with biological materials," said Michael McAlpine, an assistant professor of mechanical and aerospace engineering at Princeton and the lead researcher on the project. "Previously, researchers have suggested some strategies to tailor the electronics so that this merger is less awkward. That typically happens between a 2D sheet of electronics and a surface of the tissue. However, our work suggests a new approach -- to build and grow the biology up with the electronics synergistically and in a 3D interwoven format." … Read more

Netflix said to eliminate hundreds of classic titles

It appears to be expiration time again for certain movies on Netflix streaming, according to Slate. This time around, hundreds of classic titles from Warner Bros., MGM, and Universal will allegedly disappear from Instant queues on May 1.

That means goodbye Woody Allen's "Stardust Memories," "10 to Midnight" starring Charles Bronson, the James Bond hits "Dr. No" and "Goldfinger," and many more.

While this news may disappoint some users, streaming titles on Netflix tend to come and go. The video service often licenses TV shows and movies on an exclusive basis … Read more

Flexible smartphone curls up when it gets a call

The MorePhone is a very acrobatic smartphone. It's made with a flexible display and shape memory alloy wires. When a call comes in, it activates the wires and causes the whole phone to curl up. It's an unmistakeable visual cue that you've got someone on the line.

The curling smartphone was developed by researchers at Queen's University Human Media Lab in Canada. The thin electrophoretic display that makes the movement possible was manufactured by Plastic Logic, a company specializing in plastic electronics. The alloy wires can trigger the phone to curl up at all corners, or to curl back individual corners to indicate different events, like an incoming text message or e-mail.… Read more

Android keyboard Kalq quicker than Qwerty, scientists say

It's hard to type fast and not make any spellibg msitakes, but scientists reckon they've solved that with a new keyboard for Android tablets. Kalq is a keyboard calculated to have you typing 34 percent faster.

Developed by keyboard heroes at the Max Planck Institute for Informatics, the University of Montana, and the University of St. Andrews, Kalq -- named, like the standard Qwerty keyboard, for one of the rows of letters -- splits the keyboard in two so you can quickly type with your thumbs. … Read more

New teeny-tiny battery charges in less than a second

One of the biggest bugbears of smartphones is just how much juice they drain -- and how long they take to recharge. Batteries are also the reason many devices can't be smaller; after all, the batteries have to fit somewhere (although, given the burgeoning phablet market, that's not exactly a huge problem).

Scientists have made several recent attempts to build a better lithium ion battery. In the latest push, a team of researchers led by mechanical science and engineering professor William P. King at the University of Illinois in Urbana-Champaign has developed a new type of lithium ion battery that's just a fraction of the size of the batteries we use now -- and that can out-power the best supercapacitors. … Read more

See-through brain lets scientists spot the connections

Studying the brain can be a tricky business.

The interesting stuff, such as neurons and how they communicate, is obscured by things like fatty tissue. Usually, scientists just cut it up into paper-thin slices to study, like with Einstein's brain, but a team of scientists at Stanford University, led by Karl Deisseroth and Kwanghun Chung, have found what the director of the National Institute of Mental Health Thomas Insel is calling "one of the most important advances for doing neuroanatomy in decades."

The new technique lets researchers leave the brain intact, which puts an end to the damage that slicing can cause. It involves infusing the brain with acrylamide, which binds the proteins; once heated, it polymerizes, preserving the important molecules. Then, the brain is rinsed with sodium dodecyl sulfate (SDS) detergent, which strips the fatty lipids, leaving intact the proteins that the researchers wish to study. … Read more

Living side by side with robots

STANFORD, Calif.--When I walked onto the Stanford University campus this week and into the Volkswagen Automotive Innovation Lab, I was greeted by a short, gray robot waving his two long arms -- he was looking for a high-five.

All around me robots of all sizes were roaming the floor. I was trapped -- in the future. … Read more

High-speed cam catches cool 3D shots of snowflakes

Now that winter has passed, those of us who live in cold climes can once again appreciate the beauty of snowflakes without feeling the urge to curse them for making us dig out the shovel. And if ever snowflakes looked lovely, it's in these images shot by a high-speed camera system developed specifically to photograph them in 3D as they fell.

"Until our device, there was no good instrument for automatically photographing the shapes and sizes of snowflakes in free fall," says Tim Garrett, an associate professor of atmospheric sciences at the University of Utah and one of the developers of the cam known as MASC, or Multi-Angle Snowflake Camera. "We are photographing these snowflakes completely untouched by any device, as they exist naturally in the air."

MASC -- under development for three years -- takes 9- to 37-micron-resolution stereographic photographs of snowflakes from three angles while simultaneously measuring the speed of their fall, a highly influential factor in the location and lifetime of a storm. … Read more

Electronic girlfriend coat hugs you, talks nice to you

Japan is already known for integrating robots into everyday life, whether it's giant fembots in Tokyo's red-light district or shampooing robots that handle salon duties. Now, students from the University of Tsukuba have created a robotic girlfriend coat for lonely fellas.

The Riajyuu Coat features a belt around the midsection. Motors on the back tighten the belt, squeezing the wearer to replicate a girlfriend coming up from behind and giving him a hug. A set of headphone lets the guy listen to a high-pitched woman talking at him, apologizing for being late, and just generally coming off as cute, in an anime sort of way.… Read more
