October 2, 2014When you can’t collect all the data you need, a new algorithm tells you which to target.
July 25, 2014New scheme could enable laser rangefinders to infer depth from a hundredth as much light — and to produce images from only one nine-hundredth the light.
November 28, 2013For 65 years, most information-theoretic analyses of cryptographic systems have made a mathematical assumption that turns out to be wrong.

February 10, 2012Error-correcting codes discovered at MIT can still guarantee reliable communication, even in cellphones with failure-prone low-power chips.
August 4, 2011A technique called network coding could protect users’ privacy and providers’ content while making communications networks more efficient.
April 1, 2011Norbert Wiener gained fame as the father of cybernetics, but his earlier work on statistical descriptions of complex systems may prove more important.
