The problem is not that there isn’t enough food, but that those foods (rice, corn and wheat) don’t have enough nutrients. Now, 30,000 small farmers are growing pearl millets, a variety which has unusually high levels of iron and zinc. “We must re-marry agriculture and nutrition—the two have been too far away from each other for a long time,” says M.S. Swaminathan, the father of India’s Green Revolution. (12 min read)
The 2011 Nobel Prize in Chemistry went to Dan Shechtman for the discovery of quasicrystals. This form of solid is in between true crystals, such as salt, and amorphous, disordered solids, such as glass. Its acceptance by the scientific community has been marred with controversy. Although developed in labs in the 1980s, their natural occurrence was only confirmed recently. It took three scientists a trip to the Russian tundra armed with Kalashinovs for defence to find a few grains that proved their existence. (20 min read)

The period allows the baby to take in more blood from the placenta, but doctors have been taught by old textbooks to cut the cord as soon as possible. (5 min read)
The concept is beautiful in its simplicity: take long stretches of open canals in dry, sunny terrain, and cover them with solar panels. The solar roofs prevent the evaporation of water. And the coolness of the water, in turn, will keep the panels at a more efficient operating temperature. Some logistical issues remain, but the plan is genius. (3 min read)
