Flies smell through a Gore-Tex system

A research group led by a scientist of the RIKEN Center for Biosystems Dynamics Research (BDR) has gained important insights into the nanopores that allow the fruit fly to detect chemicals in the air, and has identified the ...

Researchers measure puncture performance of viper fangs

A team that studies how biological structures such as cactus spines and mantis shrimp appendages puncture living tissue has turned its attention to viper fangs. Specifically, the scientists wanted to know, what physical characteristics ...

Nature-inspired antibacterial metals

From aviation to medicine, various sectors are increasingly using materials that mimic the lotus plant, whose leaves have self-cleaning properties. Thanks to the bumpy surface structure covered with tube-shaped wax crystals, ...

Engineers make clear droplets produce iridescent colors

Engineers at MIT and Penn State University have found that under the right conditions, ordinary clear water droplets on a transparent surface can produce brilliant colors, without the addition of inks or dyes.

'Meta-mirror' reflects sound waves in any direction

Researchers at Duke University and Aalto University (Finland) have constructed a "meta-mirror" device capable of perfectly reflecting sound waves in any direction. The proof-of-principle demonstration is analogous to looking ...
