The efficient production of cellulosic fuels by biochemical routes will require innovation in three main areas: sustainable production of feedstocks that do not compete with food production, depolymerization of feedstocks, and conversion of feedstocks to liquid fuels. In this respect there is renewed interest in identifying plants that have optimal ...
Recently, exciting new physics and applications are emerging from metamaterials made of artificial "atoms" and "molecules." These metamaterials have inspired a series of key explorations to manipulate, store, and control the flow of information and energy at unprecedented dimensions. Yet, these groundbreaking achievements are only the tip of the iceberg, ...
Of all the natural disasters that could befall us, only an Earth impact by a large comet or asteroid has the potential to end civilization in a single blow. Yet these near-Earth objects also offer tantalizing clues to our solar system's origins, and someday could even serve as stepping-stones for ...
