Calculating the total capacity of a data network

In a two-part paper, a team of scientists from MIT, Caltech and University of Technology in Munich examined network coding and ways to both minimize error and maximize capacity. In its early years, information theory — which grew out of a landmark 1948 paper by MIT alumnus and future professor Claude Shannon — was dominated [...]

Scientists Generate Electricity From Viruses

Scientists at the Berkeley Lab have developed a way to generate power using harmless viruses that convert mechanical energy into electricity. Their generator is the first of its kind to produce electricity by harnessing the piezoelectric properties of a biological material and could lead to devices that harness electrical energy from the vibrations of everyday [...]

power buoy floats in Monterey Bay

In an effort to harness the power of ocean waves, engineers designed and built a floating “power buoy” that measures 8 feet across, 10 feet wide and 18 feet long. The buoy uses the upward and downward motion of waves, combined with the weight of a metal plate, to move a hydraulic piston, resulting in [...]

inhibit microbial growth in cotton socks, T-shirts and other clothes using silver particles

The future might smell better thanks to scientists at the USDA that are investigating new antimicrobial treatments for clothing. Using an environmentally friendly method to produce silver nanoparticles, researchers are prompting the silver nanoparticles to form directly on cotton fibers, eliminating the handling and storage of the antimicrobial agents prior to application. Socks, T-shirts and [...]
