Scientists have been hard at work for more than 20 years to instruct biological systems, such as E. coli cells, to produce proteins they don't naturally produce.
In micro- and nanotechnology, highly precise components with tall, narrow structures (high aspect ratios) made from semiconductor materials like silicon are important.
Brazilian authorities have temporarily relaxed an environmental rule for the Belo Monte hydropower plant on the Xingu River in the northeastern Amazon. The change comes in anticipation of another potentially severe, El-Niño-fueled dry season.
For centuries, scientists have been fascinated by the remarkable coordinated movements of flocking birds, swarming insects and schooling fish. Researchers have studied these natural phenomena to understand the rules of interactions between individuals that can produce complex group-level behavior.
