NEW YORK--For months, a debate has raged in the media and on Capitol Hill about whether or not society (and the law) should allow 3D-printed guns.

After listening to Cody Wilson speak for a few minutes, one can't help but come away feeling that the national discussion is moot: 3D-printed firearms are inevitable.

Today at the Inside 3D Printing Conference and Expo, Wilson, the founder and director of Defense Distributed, argued for an environment in which people can use 3D printers to make guns.

It's not that he doesn't recognize -- or care -- that there's … Read more

An interaction designer who makes sci-fi short films has spent the past three years developing what he says is the world's first Braille-enabled smartphone. He said that if testing goes well, the phones could hit stores by the end of this year.

Thanks in part to award money from Rolex, India-based designer Sumit Dagar has been collaborating with the Indian Institute of Technology Delhi and L V Prasad Eye Institute in Hyderabad to develop a prototype. The smartphone employs a haptic touch screen that elevates and depresses the content it receives, thereby transforming the data into touchable patterns.

Yes, this phone is essentially a shapeshifter.… Read more

NEW YORK--Guitars. Skulls. Bracelets. Colorful heads. And so much more.

That was what was on display at the Inside 3D Printing event here today, a celebration of all things 3D printing, and one of the first-ever professional events dedicated solely to the decades-old technology that has been taking the world by storm over the last few years.

Just about ever leading company in the field was on hand, from 3D Systems to MakerBot to Stratasys, and many others. And hundreds of people packed the event hall, eager to see the latest machines, and hear from some of the leaders in … Read more

For the roughly three percent of the population that suffers from amblyopia, or "lazy eye," the best current treatment option -- covering the stronger eye to force the weaker one into better behavior -- works only some of the time in kids and has been totally ineffective in adults.

Now researchers out of McGill University in Montreal say that playing Tetris may ultimately treat the disorder in adults because the puzzle video game trains the eyes to work together as information is distributed across them in a complementary fashion.

"The key to improving vision for adults, who … Read more

Don't cry for Tyrannosaurus rex and its teensy-weensy arms. It was in good company in the dinosaur kingdom with a recently discovered new species found in Madagascar. After a nearly 10-year dino drought on the island, two researchers uncovered the Dahalokely tokana, a creature with big back legs and itsy-bitsy front arms.

The critter was about as tall as a human male, but had a length of 9 to 14 feet. What helped the researchers peg it as a new species were some unique characteristics of the vertebrae, including the shape of cavities on the side. For dinosaur species, that's a lot like finding a fingerprint.

Besides being a new species, Dahalokely is also helping to fill in some puzzling gaps in the fossil record for Madagascar. "We had always suspected that abelisauroids were in Madagascar 90 million years ago, because they were also found in younger rocks on the island. Dahalokely nicely confirms this hypothesis," said project leader Andrew Farke, curator of paleontology at the Alf Museum.… Read more

Google Earth has been around for years, but thanks to a new integration with Leap Motion, you can now soar through the digital representation of our planet like never before.

Starting with the release today of Google Earth 7.1, those who use Leap Motion's hands-free 3D gesture control technology will be able to control the exploration tool, "flying" through the software by simply waving their hands.

As of right now, unfortunately, the only people who will be able to benefit from this partnership are the thousands of developers who have already received one of Leap Motion'… Read more

There are many gestural interfaces under development, but our fingers remain one of the most useful tools we have. Fujitsu's FingerLink lets your fingers control a scanner and projector for printed information, acting as a bridge between digital and analog tech.

The prototype uses off-the-shelf cameras and projectors. Fujitsu's image-processing software links the two.

It can accurately detect where your fingers are as you touch or swipe any printed matter, letting you copy text or images and project them elsewhere. The size of projected images can similarly be adjusted with a fingertip. … Read more

A researcher who used to work in digital television has just led a team of Columbia University engineers to win the Sage Bionetworks / DREAM Breast Cancer Prognosis Challenge.

Dimitris Anastassiou, who is now a systems biologist (meaning he investigates interactions within biological systems), reports in the April 17 issue of Science Translational Medicine that his team's winning computation model is extremely predictive of breast cancer survival.

Before the challenge, Anastassiou and his team identified what they call "attractor metagenes," which are genetic signatures expressed in almost the exact same way across many types of cancer. Their new … Read more

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
