Transistors that wrap around tissues: New implanted devices may reshape medicine
(Phys.org) —Researchers from The University of Texas at Dallas and the University of Tokyo have created electronic devices that become soft when implanted inside the body and can deploy to grip 3-D objects, ...
The hemihelix: Scientists discover a new shape using rubber bands (w/ video)
While setting out to fabricate new springs to support a cephalopod-inspired imaging project, a group of Harvard researchers stumbled upon a surprising discovery: the hemihelix, a shape rarely seen in nature.
After 400 years, mathematicians find a new class of solid shapes
The work of the Greek polymath Plato has kept millions of people busy for millennia. A few among them have been mathematicians who have obsessed about Platonic solids, a class of geometric forms that are ...
Morphing composite material has mighty potential (w/ Video)
(Phys.org) —Heating a sheet of plastic may not bring it to life – but it sure looks like it does in new experiments at Rice University.
