Tapping sun’s light and heat to make hydrogen
Researchers have demonstrated a highly efficient means of splitting water molecules to generate hydrogen fuel.
- Physics
Light pulse hovers in atom capsule
A new way to freeze light pulses in midflight preserves the pulses' optical energy and may eventually lead to using stationary light in optical circuits and quantum computers.
- 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.
- Physics
Topsy Turvy: In neutrons and protons, quarks take wrong turns
Revved-up particles, namely quarks, spinning inside neutrons in the opposite direction to that of the neutrons themselves, challenge the prevailing model of how quarks behave.

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.

Glow with the flow
Potentially usable electricity flows when water is forced through millions of ceramic tubes thinner than a human hair.

Dune leapfrogging is deciphered
Some wind-propelled sand dunes can pass right through each other if their relative sizes are right, new computer simulations indicate—although the sand grains of one dune don't actually penetrate through the other dune.

Hints emerge of a four-quark particle
Previously observed only in twos, threes, and perhaps in fives, quarks and antiquarks in a newfound particle may have glommed together to form a never-before-seen foursome.
