Injectable ‘smart sponge’ controls diabetes, presents new targeted drug delivery method

DNP Targeted drug delivery via sponge

Diabetics might appreciate high-tech glucose sensors when they're available, but the option for other advanced treatments is certainly intriguing. Take, for example, this new method developed by North Carolina State University researchers that uses injectable sponge to control blood sugar levels. No, it's not the same sponge you use to clean at home -- the material is made out of a substance taken from crab and shrimp shells called chitosan. This spongy material forms a matrix that's approximately 250 micrometers in diameter, where a rise in blood sugar causes a reaction in the pores that leads to the drug's release.

Fighting diabetes is but one of the things this miraculous sponge can be used for; developed further, it could even "intelligently" release anticancer drugs whenever the chitosan reacts to tumors or cancer cells in close proximity. Seems like medical technology is getting smarter with each passing day.

Liquid metal for 3D printing could lead to bendy electronics, T-1000

DNP 3D printing liquid metal a la Terminator, yo

3D printing is awesome, yet it still has a lot of untapped potential -- you can use it to create terrifying spiderbots and even tiny drones, but you can't make electronic components out of pools of plastic. Thankfully, a team of North Carolina State University researchers have discovered a mixture of liquid metal that can retain shapes, which could eventually be used for 3D printing. Liquid metals naturally have the tendency to merge, but alloys composed of gallium and indium combined form a skin around the material. This allows researchers to create structures by piling drops on top of each other using a syringe, as well as to create specific shapes by using templates. The team is looking for a way to use the mixture with existing 3D printing technologies, but it might take some before it's widely used as it currently costs 100 times more than plastic. We hope they address both issues in the near future, so we can conjure up futuristic tech like bendy electronics, or maybe even build a body to go with that artificial skin.

NC State’s new efficient pico projector raises hopes for smartphone cinema

NC State's new efficient projector

A team at North Carolina State University has developed a new liquid crystal projector that could spell the end of bulky and noisy cinema gear. Conventional tech passes unpolarized light through a filter, but the process is so inefficient that nearly 50 percent of the energy is wasted just keeping things cool. Fortunately, the Wolfpack and ImagineOptix filter claims to be 90 percent efficient -- meaning that future projectors could be far sleeker. It's also a good sign for future smartphone pico projectors, although we're not sure how the owners of our local theater will feel when we start undercutting them with just a phone and a white wall.

Researchers partially automate CPU core design, aim to fast track new PC processor production

NC State researchers automate CPU core design, potentially put new PC processors on the production fast trackTired of the year wait (or more) in between new silicon architecture offerings from Chipzilla and AMD? Well, if some Wolfpack researchers have anything to say about it, we'll measure that wait in months thanks to a new CPU core design tool that automates part of the process. Creating a new CPU core is, on a high level, a two step procedure. First, the architectural specification is created, which sets the core's dimensions and arranges its components. That requires some heavy intellectual lifting, and involves teams of engineers to complete. Previously, similar manpower was needed for the second step, where the architecture spec is translated into an implementation design that can be fabricated in a factory. No longer. The aforementioned NC State boffins have come up with a tool that allows engineers to input their architecture specification, and it generates an implementation design that's used to draw up manufacturing blueprints. The result? Considerable time and manpower savings in creating newly designed CPU cores, which means that all those leaked roadmaps we're so fond of could be in serious need of revision sometime soon.
