This smart bandage releases meds on command for better healing

Taking care of a cut or scrape usually means swapping out the bandage a few times, and maybe putting a little healing cream or hydrogel on there. But what if the dressing could dispense that stuff on its own? That’s the idea behind a smart bandage now being tested by engineers from the University of Nebraska-Lincoln, Harvard and MIT.

3D-printed space habitats earn $400K in prizes at NASA competition

One of the many considerations we will have should we decide at last to colonize another planet is where we’ll live. Should we bring inflatable habitats? Should we ship girders and metal sheets? Or should we, as explored in a recent NASA challenge, 3D-print the structures right there on the planet in question? Two universities’ early efforts to do so earned them a combined $400,000 at a competition held last week. Continue reading 3D-printed space habitats earn $400K in prizes at NASA competition

This Amazing Flashlight Is Made From A Sheet Of Paper

When we think of wonder materials, high-tech innovations like graphene or eco-friendly solutions like bricks grown from mushrooms come to mind. But it turns out that one of the most basic materials still has a few tricks up its sleeve: paper. The Tokyo-based studio Nendo performed a bit of design magic and transformed a sheet of paper into a working flashlight with the help of conductive inks from the startup AgIC.

Paper Torch is made from a sheet of heavy duty, water-resistant paper that’s typically used on election ballots. Nendo then printed a circuit board using metallic ink from AgIC directly onto the paper and glued an LED bulb and two button-sized batteries to it. Electricity flows from the batteries to the bulb through the printed pattern, eliminating the need for wire circuitry and making the flashlight less expensive to manufacture than something you’d pick up at Best Buy.

But the alchemy doesn’t stop there. Roll the paper tighter and the light becomes brighter. Since the electricity has a shorter distance to travel–and less resistance–it’s stronger and can illuminate the bulb with more intensity. Want to change the color temperature? Roll the paper with the checkerboard pattern inside for a warm, yellow-tinged light or the blank half inside for a cooler white light.

Nendo sees potential applications for disaster relief and emergencies since the product is compact, does not require complex manufacturing, and is inexpensive to produce. Plus, it’s also the perfect party trick.
