At the International Earth Rotation and Reference Systems Service in Paris, a quiet calculation takes place several times a year. Technicians compare the world’s atomic clocks, which measure time with ...

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 ...

If today feels like it's flying by, you can blame it on our spinning planet: A group of scientists tracking Earth's rotation predicts that the day will be a fraction of a second shorter than normal.

Earth rotates once in about 24 hours with respect to the Sun, but once every 23 hours, 56 minutes and 4 seconds with respect to other distant stars. Scientists call this difference crucial to ...

Scientists announced Monday that Earth is rotating slightly faster than normal, resulting in what is expected to become the second-shortest day ever recorded since precise atomic timekeeping began.

When we talk about feats of engineering, very few megastructures on Earth rival the sheer scale of China's Three Gorges Dam. It's located in Hubei province, spanning the mighty Yangtze River, and it's ...

The United States led global production of rare earth elements (REEs) until the mid-1990s, when China emerged as the dominant supplier. China maintained near-total control of the market until 2012.

James O'Donoghue receives funding from the UK Science and Technology Facilities Council (STFC). Earth will complete a rotation 1.33 milliseconds earlier than usual on Tuesday, August 5. That makes it ...

If you haven’t accomplished as much this summer as you had hoped to, you can blame forces far beyond your control: a few of these dog days, by one measure, are among the shortest you’ve ever lived ...
