New “tricorder” technology might be able to “hear” tumors growing.

A team of scientists from Stanford University is testing a new “tricorder” technology able to remotely detect abnormal matter, such as buried plastic explosives or even early stage cancers in humans, by manipulating microwaves and ultrasound. The new “radio frequency (RF)/ultrasound hybrid imaging system,” the brainchild of Assistant Professor Amin Arbabian and Research Professor Pierre Khuri-Yakub, was designed for remote detection of embedded objects in a number of different kinds of matter, i...

3D printed objects may be toxic

Parts produced by some commercial 3D printers may be toxic, according to a new study that raises concerns about how to dispose of parts and waste materials from the devices which are becoming increasingly popular. Researchers at the University of California, Riverside studied two common types of 3D printers, one that melts plastic to build a part, and another that uses light to turn a liquid into a solid part. They found that parts from both types of printers were measurably toxic to zebrafish e...

Miniature invisibility cloak that can conceal 3-D objects by refracting light waves.

Scientists at the Berkeley Lab and UC Berkeley have created an invisibility cloak made from a thin material covered with millions of gold-plated antennae which wraps around an object and uses the antennae to divert light waves from its surface, rendering it undetectable to the human eye. Light reflects off the cloak as if it were reflecting off a flat mirror. Unlike the fictional character, the ultrathin cloak is real, and it successfully concealed microscopic 3D objects from detection in vis...
