The High-Performance All-Electric Home

In the 1950s, when nuclear energy was booming and hydroelectric dams were laying across rivers like tourniquets, the all-electric home became a thing. It didn’t matter that the electric heating technologies of the time were vastly inefficient. The promise of electricity that was “too cheap to meter” meant that people could use it to their heart’s delight.

Photosynthesis Differs in Rice Varieties — Natural Diversity Could Boost Yields

Rice is a direct source of calories for more people than any other and serves as the main staple for some 560 million chronically hungry people in Asia. With over 120,000 varieties of cultivated rice (Oryza sativa) across the globe, there is a wealth of natural diversity to be mined by plant scientists to increase yields. A team from the University of Illinois and the International Rice Research Institute (IRRI) examined how 14 diverse varieties photosynthesize—the process by which all crops convert sunlight energy into sugars that ultimately become our food.
