Selectively Shielding

Wireless recharging using magnetic fields sounds like a great advance, but it could present problems for some technologies. The David R. Smith research group in Duke Engineering has developed a thin sheet of metamaterial in which repeating patterns of conductive material would shield electronics from a charger's magnetic field while letting certain frequencies through. Such a shield might also be used as a reflector to focus wireless charging and make it more efficient.

 

Inside an Ancient Monkey Skull

The brain hidden inside the oldest known Old World monkey skull has been visualized for the first time. The ancient monkey, known as Victoriapithecus, first made headlines in 1997 when its 15 million-year-old skull was discovered on an island in Kenya’s Lake Victoria. Now, thanks to X-ray imaging, researchers have peered inside its cranial cavity and created a three-dimensional computer model of what the animal’s brain looked like.

Making New Connections

This composite image from the lab of Scott Soderling in Cell Biology shows both the behavior and structure of a protein called WRP that occurs almost exclusively in neurons. Tagged green, the protein homes in on slender, red-labeled dendrites on the receiving end of a neuron. A computer-rendered model at the center of the image shows the structure of the portion of WRP that binds to the surface of the dendrite.
