Scientists have designed ‘programmable’ pasta shapes that transform when they’re cooked





What if your pasta could lie flat and occupy less shape when packaged, and morph into its desired shape when cooking? As odd as that design brief may sound, scientists at Carnegie Mellon University and Zhejiang University City College are trying to figure out how to make pasta more ‘efficient’. Sure, it may give a couple of traditional Italian cooks and nonnas a panic attack, but hey… science does what science does, right?

Working on principles that are quite similar to those found in soft robotics and origami, these new pasta shapes start out as flat sheets of dried dough that warp into their signature design when you boil them in water. The secret lies in those unique ridges pressed into the pasta shapes that cause it to warp in different directions when the dough absorbs water and expands. The uniquely calibrated ridge depth and spacing, along with the pasta’s overall shape, result in some wonderfully unusual designs. It’s safe to say that the scientists must have gained a few pounds during the prototyping and testing phases. After all, who wouldn’t want to eat bowl after bowl of pasta for the sake of science??

The new pasta shapes are a combination of familiar and absolutely out-of-the-box forms, all calibrated to do two jobs – holding the sauce and tasting fabulous. Some of them are loosely based on popular designs like garganelli, fusilli, and ziti, while other shapes completely redefine the cuisine with how they look… with one clear distinction, creating a pasta that starts off as a flat, scored sheet of dough that transforms into a 3D shape when cooked.

“This mechanism allows us to demonstrate approaches that could improve the efficiency of certain food manufacturing processes and facilitate the sustainable packaging of food, for instance, by creating morphing pasta that can be flat-packed to reduce the air space in the packaging”, say the researchers at Carnegie Mellon University and Zhejiang University.

Tactus’ morphing smartphone and tablet display hands-on

Tactus technology gives your display keys when you want them, full touchscreen when you don't

Tactus Technology, a small start-up out of Fremont, CA, made a big splash at this year's Society for Information Display (SID) conference. The company, which came to Boston, MA toting a single product, showcased an early prototype of its morphing touchscreen display. The screen, which looks and acts like all other smartphone and tablet displays, has a very special and unique feature: it can dynamically create and remove tactile keys on demand. Tactus utilizes a specially designed window that sits directly on top of a display's touch sensor -- which we're told can be fitted to almost any touchscreen -- that has specially designed channels. A "proprietary oil" is, at the behest of the underlying operating system, forced in and out of these channels to raise the display surface and create a tactile interface for the end-user. It's a concept that, much to the delight of ardent smartphone and tablet keyboard lovers, can provide a physical input experience without sacrificing screen real estate. Have a look at our hands-on gallery then saunter past the break to see this tactile touchscreen in action and read our impressions.

Mighty morphing hexapod bot is back, now rolls with the punches

Image
It's been awhile since we last saw Kåre Halvorsen's morphing hexapod ball-shaped bot, and in the interim it picked up some new tricks. Before, the MorpHex could only maneuver by scurrying around on its six legs, but now it can move around while still in spherical form. It works by periodically protruding its polycarbonate panels to get rolling, and it stops and turns in similar fashion. Additionally, it's learned some nifty new dance moves and acquired the ability to flummox small children. Don't take our word for it, though, see the thing in action after the break.
