As life has evolved, its complexity has increased exponentially, just like Moore’s law. Now geneticists have extrapolated this trend backwards and found that by this measure, life is older than the Earth itself.
Better technology and high battery costs have revived interest in hydrogen-guzzling vehicles.
The U.S. will still need more big breakthroughs to eliminate the need for imported oil.
Manufacturing, transporting, and constructing the world’s largest wind turbine represents a unique challenge.
Chemical producers abandoned the U.S. in droves. Cheap natural gas is luring them back.
Fast reactors can shrink nuclear-waste stockpiles, but can designers tame the inherent hazards?
Advanced materials and smart design could lower turbine blade costs by 40 percent.
