Carnegie Mellon scientists are creating cutting-edge technology that could one day solve the shortage of heart transplants, which are currently needed to repair damaged organs.

“We’ve been able to take MRI images of coronary arteries and 3-D images of embryonic hearts and 3-D bioprint them with unprecedented resolution and quality out of very soft materials like collagens, alginates and fibrins,” said Adam Feinberg, an associate professor of Materials Science and Engineering and Biomedical Engineering at Carnegie Mellon University.

Samsung’s latest battery prototypes could lead not only to more powerful wearables, but also to unusual ones. The first model called Band is meant to be attached to smartwatch straps, as its name implies, to add as much as 50 percent of the device’s original battery life. Stripe, on the other hand, is the thin, bendy strip the model above is holding in her hands — and the more versatile between the two. Since it’s extremely thin (it has a depth measuring 0.3mm), it could be used to create all kinds of wearables, such as smart necklaces and headbands, or even interactive clothing designs. According to Samsung, it has higher energy density than current comparable batteries, though it didn’t name any particular brand and model.
