"Omniphobic" might sound like a way to describe someone who is afraid of everything, but it actually refers to a special type of surface that repels virtually any liquid. Such surfaces could potentially be used in everything ...

Determining the timing of methanogen evolution

Early forms of life very likely had metabolisms that transformed the primordial Earth, such as initiating the carbon cycle and producing most of the planet's oxygen through photosynthesis. About 3.5 billion years ago, the ...

Silk fibers could be high-tech 'natural metamaterials'

New research has demonstrated how the nano-architecture of a silkworm's fiber causes "Anderson localization of light," a discovery that could lead to various innovations and a better understanding of light transport and heat ...
