New DNA-based chip can be programmed to solve complex math problems

The term DNA immediately calls to mind the double-stranded helix that contains all our genetic information. But the individual units of its two strands are pairs of molecules bonded with each other in a selective, complementary ...

Copying the small structures of Salvinia leaves

Several plants and animals have evolved surfaces with long-term (i.e., days to months) air-retainability to prevent wetting and submersion. One example is Salvinia, a plant floating on water. The secret "how do they maintain ...
