China's state news agency reported on 19 September that the country is planning to set up a scientific research outpost on Mount Everest. The research station, which will be located near the mountain's Base Camp, 5000 meters above sea level, will be used to study the relationship between the atmospheric conditions in that area, known as the Qinghai-Tibet Plateau, and global patterns.

A group of researchers from the Massachusetts Institute of Technology, the University of Tennessee, and the U.S. Naval Research Laboratory have come up with a recipe that allows them to take advantage of the photosynthetic proteins in spinach and other plants, which capture energy from sunlight. When laser light is shined on a "spinach sandwich" containing ground photosynthetic proteins mixed with detergent peptides, a tiny current is produced.
