Paint by Pixel
Aaron Hertzmann is both a computer scientist and a painter. Among his art-related programming projects, he has developed a way for computers to refashion images and animations to reflect different painting styles. Other work includes a stretched “canvas” that projects a continually-changing painting of the viewer and a learning-by-example system that animates characters based on […]

Snappy DNA: Long strand folds into octahedron
By harnessing the self-assembling properties of DNA, researchers coerced a single strand of the genetic material to assume the shape of an octahedron.

Software enhances view of aircraft flaws
New software can run an ultrasonic machine that will map corrosion beneath the surface of an airplane more quickly, safely, and effectively than can existing devices.

Tapping sun’s light and heat to make hydrogen
Researchers have demonstrated a highly efficient means of splitting water molecules to generate hydrogen fuel.
- Tech
Electronic skin senses touch
A pressure-detecting membrane laminated onto a sheet of flexible plastic electronics may lead to artificial skin for robots.
- Tech
Flashy Transistors: Electronic workhorses also shed light
Researchers have discovered that the transistor can emit light, a yet-untapped talent.
- Tech
Gene Screen: Ultrasensitive nanowires catch mutations
Researchers have devised a nanowire sensor that binds to DNA molecules and produces an electrical signal almost instantaneously.

Gel Bots? Vibrated goo mimics slithery motions
The ability of soft, jellylike hydrogels to move as do snails, snakes, and inchworms may point the way to a new class of squishy robots that promise to be simple, quiet, and versatile.
