In central China, the Yangtze River is held back by an engineering marvel so massive that it doesn’t just generate power or ...

Researchers have been on a long quest to harness carbon-free energy from natural processes, from tapping into tidal forces to mimicking the fusion reactions that occur in stars. Now, a team of ...

For more than a century, engineers have chased new ways to turn the planet’s natural motions into usable power, from tides to geothermal heat. Now a small group of physicists says Earth’s own magnetic ...

One giant dam has already nudged the way our planet turns. When the enormous Three Gorges Dam reservoir in China filled with tens of billions of tons of water, NASA calculations showed that the extra ...

A trio of US researchers claim to have successfully tested predictions that it's possible to harvest clean energy from the natural rhythms and processes of our planet, generating electricity as Earth ...

Climate change is altering the Earth to its literal core, new research suggests. As polar and glacial ice melts because of global warming, water that was once concentrated at the top and the bottom of ...

Earth is spinning faster this summer, making the days marginally shorter and attracting the attention of scientists and timekeepers. July 10 was the shortest day of the year so far, lasting 1.36 ...

The planet’s rotation fluctuates as it travels around the sun, and measurements suggest we’re losing more than a millisecond during the long days of summer. By Jacey Fortin This article was updated ...
