Sunlight can produce energy and clean water at the same time
A new device can make electricity from the sun. What makes it truly special, however: It uses waste heat from the system to turn dirty water or salty water into drinking water.

This robot’s parts are helpless alone, but turn smart as they team up
In a new system called “particle robotics,” many small, simple helpless units can seemingly come to life and start moving when amassed into a team.

Ocean energy could be the wave of the future
Energy systems that turn the power of ocean waves into electrical energy could be on the horizon — or pumping away near the sea floor.

New forensic technique may better gauge age at death
An 18-year-old student from Ackworth, England, has come up with a better way to estimate the age at death for many human remains. It needs only a CT scan of the skull.
