Smaller pixels, smaller thermal cameras for warfighters

The military uses long-wave infrared (LWIR) cameras as thermal imagers to detect humans at night. These cameras are usually mounted on vehicles as they are too large to be carried by a single warfighter and are too expensive ...

Nanosuits help small creatures survive a vacuum

(Phys.org) —Scientists use scanning electron microscopes (SEMs) to study tiny structures in small organisms. SEMs can only work in a high vacuum, and exposure to such a vacuum normally causes living things to die very ...

Slowing down microwaves in a chip

EPFL scientists have succeeded in capturing a microwave pulse within a chip for several milliseconds before releasing it with little loss. This extraordinary delay normally requires hundreds of miles of electrical cable, ...

How an objective audiometric test can become even more reliable

Not only can the human ear detect sounds, it can also generate them. If the ear hears the two upper tones of a major triad, it produces the fundamental of the chord which can then be measured. This phenomenon, called "otoacoustic ...

Hagfish slime as a model for tomorrow's natural fabrics

Nylon, Kevlar and other synthetic fabrics: Step aside. If new scientific research pans out, people may be sporting shirts, blouses and other garments made from fibers modeled after those in the icky, super-strong slime from ...

Electronics of nature's nano machines

(Phys.org)—A team from the Cardiff University's Schools of Biosciences and Physics and Astronomy have made a breakthrough in our understanding of proteins - the workhorse molecules of the cell and nature's very own nano ...
