Ultrathin device harvests electricity from human motion
Vanderbilt undergraduate Thomas Metke demonstrates the ultrathin energy harvesting device which is taped across his elbow. As he flexes his arm the current the...
Explosions of Jupiter’s aurora linked to extraordinary planet-moon interaction
In this artist's rendering, flows of electrically charged ions and electrons accelerate along Jupiter's magnetic field lines (fountain-like blue curves), triggering auroras (blue rings)...

Chitchat, small talk could serve an evolutionary need to bond with others
Princeton University research suggests that idle conversation could be a social-bonding tool passed down from primates. The researchers found that ringtailed lemurs (above) use...
