Engineers have designed a metamaterial device that can solve integral equations. The device works by encoding parameters into the properties of an incoming electromagnetic wave; once inside, the device’s unique structure manipulates the wave in such a way that it exits encoded with the solution to a pre-set integral equation for that arbitrary input.

The field of metamaterials involves desig...

Scientists develop a robust experiment that shows human brain waves respond to changes in Earth-strength magnetic fields. Many humans are able to unconsciously detect changes in Earth-strength magnetic fields, according to scientists at Caltech and the University of Tokyo.

The study, led by geoscientist Joseph Kirschvink (BS, MS ’75) and neuroscientist Shin Shimojo at Caltech as well as neuroenginee...

Women who have reached menopause are at a greater risk of developing osteoporosis, which can lead to bone fractures and long-term impairment of mobility. Studies have suggested a link between reduced bone density and low estrogen levels due to menopause, but the basis for this link is unclear. Researchers found that the protein Sema3A plays a key role in maintaining healthy bones, suggesting a new therapeutic avenue to treat osteoporosis.

Bone is a complex...

Smart clothing has had a problem with its power sources and moisture permeability, which causes the devices to malfunction. This problem has now been overcome by a KAIST research team, who developed a textile-based wearable display module technology that is washable and does not require an external power source.

To ease out the problem of external power sources and enhance the practicability of wearable displays, Professor Kyung Cheol Choi from the School of Electrical Engineering and his team fabricated their wearing display modules on real textiles that integrated polymer solar cells (PSCs) with organic light emitting diodes (OLEDs).

PSCs have been one of the most promising candidates for a next-generation...
