Study determines best arrangement of tidal sails device

In the long sprint to find new sources of clean, low-cost power, slow and steady might win the race—the slow-moving water of currents and tides, that is. Just as wind turbines tap into the energy of flowing air to generate ...

Precious Western Australia mineral geologically 'young'

Scientists at Curtin University have chronicled the genesis of a particular type of iron deposit in the state's north, finding that the valuable mineral formed relatively late in Western Australia's evolution.

Invasive snails target of USGS environmental DNA study

(Phys.org) —Researchers at the University of Idaho and the U.S. Geological Survey have developed a way to identify New Zealand mudsnail infestations in their earliest stages – using only the small bits of DNA the snails ...

Turning the tide to energy

NASA researchers who developed a new way to power robotic underwater vehicles believe a spin-off technology could help convert ocean energy into electrical energy on a much larger scale. The researchers hope that clean, renewable ...

Scientists to tap river currents to create clean energy

In the eerie green glow of flashing lasers in a darkened University of Michigan lab, a cylinder on springs moves methodically up and down in a giant tank as water flows over it, simulating a stream.
