Why some big corporations must split up to survive

It's been happening a lot lately. General Electric, once the epitome of a sprawling conglomerate, is splitting into three stand-alone health care, energy, and aerospace corporations. The Kellogg Company is trifurcating as ...

New photodetector design inspired by plant photosynthesis

Researchers have developed a new type of high-efficiency photodetector inspired by the photosynthetic complexes plants use to turn sunlight into energy. Photodetectors are used in cameras, optical communication systems and ...

Researchers create flow-driven rotors at the nanoscale

Researchers from TU Delft have constructed the smallest flow-driven motors in the world. Inspired by iconic Dutch windmills and biological motor proteins, they created a self-configuring, flow-driven rotor from DNA that converts ...

How electric fish were able to evolve electric organs

Electric organs help electric fish, such as the electric eel, do all sorts of amazing things: They send and receive signals that are akin to bird songs, helping them to recognize other electric fish by species, sex and even ...

Achieving higher performance with potassium ion battery

Supercapacitors are emerging as alternatives to lithium-ion batteries, offering higher power densities and longer lifetimes (number of cycles where capacity is maintained). A supercapacitor is like a cross between a battery ...

WHO says 99% of world's population breathes poor-quality air

The U.N. health agency says nearly everybody in the world breathes air that doesn't meet its standards for air quality, calling for more action to reduce fossil-fuel use, which generates pollutants that cause respiratory ...
