Now this is how it's done – Cornell's Baxter robot, handling a knife safely

If you were buying a kitchen knife in a supermarket, you wouldn't expect the cashier to swing it dangerously close to you as they were ringing it up. If that cashier were a robot, though, it wouldn't know any better – unless it had been taught otherwise. That's just what engineers at Cornell University have done, using a unique new technique.  Read More

Doctoral student Vinay Pagay holds one of the chips

Whether you're growing wine grapes or mixing cement, there are some situations in which it's vitally important to monitor moisture content. Normally water sensors are used, although these can be both large and expensive. Now, however, a team from Cornell University has created a water-sensing silicon chip that's not only tiny, but is also reportedly "a hundred times more sensitive than current devices." What's more, the chips might be possible to mass-produce for just $5 a pop.  Read More

Cornell professor David Muller and grad student Pinshane Huang show a model of the atomic ...

In 2012, a one-molecule thick layer of silica glass was accidently made in the laboratory of Cornell professor David Muller, allowing the atoms in a glass to be seen individually for the first time. Now, Guinness World Records has identified this ultimately thin glass as a 2014 World Record.  Read More

Prof. William Dichtel and Deepti Gopalakrishnan with samples of the polymer

Detecting bombs in places such as airports could be getting easier, thanks to a new fluorescing polymer. While you might expect the material to glow in the presence of explosives, they actually cause it to stop glowing.  Read More

The anticipatory robot pouring beer

What’s better than as robot bartender that can pour you a beer? How about a robot waiter that can see you need a refill and comes over to pour you another one. Hema S. Koppula, a Cornell graduate student in computer science, and Ashutosh Saxena, an assistant professor of computer science are working at Cornell’s Personal Robotics Lab on just such a robot. Using a PR-2 robot, they've programmed it to not only carry out everyday tasks, but to anticipate human behavior and adjust its actions.  Read More

Researcher Lawrence Bonassar holds a fabricated ear created with a 3D printer (Photo: Lind...

When a child is born with the congenital deformity known as microtia, they have an underdeveloped external ear – also known as the pinna. Even though their inner ear may be normal, the lack of the external structure can affect their hearing, plus it looks unusual. Normally, a replacement pinna is made from a foam-like material (or sometimes even cartilage from the rib cage) and implanted under the skin, although these don’t always look particularly natural. Now, scientists from Cornell University have developed a more realistic pinna grown from biological material, using a 3D printer.  Read More

Students at Cornell University’s College of Veterinary Medicine can train in a simulation ...

Medical students have been honing their skills on human simulations for years and Cornell University’s College of Veterinary Medicine has been using the world's first robotic dog simulator Robo-Jerry II and Robo-Fluffy, his feline counterpart, to give aspiring vets experience since 2010. The robo-pets now have a new home in the form of a new robotic simulation center the University claims is the first of its kind in the world, with work underway on a more advanced robotic dog called "Butch" that will boast more realistic features and which will run on cheap, standard components.  Read More

DNA hydrogel letters collapse, flow, and reform into their original shape

Every now and again, Cornell University Professor Dan Luo gets a surprise. His research team has discovered a new variety of hydrogel – like Jello, except made with DNA instead of gelatin. When full of water, it is a soft, elastic solid. But when the water is removed, the hydrogel collapses, losing its shape. The resulting material pours like a liquid, and conforms to the shape of its container. The most interesting part, however, is that the liquid hydrogel remembers its shape. Add water and you get back the original Jello-like shape. Terminator T-1000, anyone?  Read More

A computer model (left) and a physical model of it, created using the new software

Take a look at all the Portal toys that are currently available, and you’ll realize just how much gamers like to own physical models of the digital characters that they know so well. When it comes to characters that are really physically “weird,” though, there can be a problem – goofy anatomy that works in a computer-generated world may not work in the real world. In other words, a physical model of a monster from a video game may be too top-heavy to stand up on its own, its arms may positioned in such a way that they can’t bend properly, or it may otherwise just be plain ol’ gimped. However, new software has been designed to solve those problems – it takes any three-dimensional computer character, and then uses a 3D printer to create a fully-assembled articulated figure based on it.  Read More

A single dose of a new nicotine vaccine could provide lifetime protection from the pleasur...

Researchers at Weill Cornell Medical College have developed a vaccine that could help existing smokers quit for good and prevent those yet to try cigarettes from ever becoming addicted. The vaccine turns the recipient’s kidney into a factory continuously churning out antibodies that clear the bloodstream of nicotine before it has a chance to reach the brain and deliver it’s addictive rush. Unlike previously tested nicotine vaccines that only last a few weeks, the effects of a single dose of this new vaccine should last a lifetime.  Read More
