Phys.org / Six unusual structures identified at Earth's core-mantle boundary with the help of deep learning

Since scientists can't drill 2,900 km (1,800 miles) to the boundary between Earth's core and deep mantle, they must use information relayed by seismic waves recorded during earthquakes to study this region. In a new study ...

Phys.org / 'Quiet' pulsar suddenly reveals three glitches in 15 years of observations

Using more than 15 years of observations from the Parkes radio telescope, astronomers detected three rotational glitches in the pulsar PSR J1637−4642—a young neutron star that had shown no signs of glitches since its discovery. ...

Dialog / A black hole as light as 40 tons can exist inside a star if dark matter helps

In 1974, Stephen Hawking made a prediction that transformed our understanding of black holes. Black holes, he showed, are not truly black: They slowly lose energy through a quantum process now known as Hawking radiation. ...

Phys.org / Lakes aren't just storing water—they're changing the carbon cycle

Lakes may look like picturesque stopping points along a river or stream, but they can have a big influence on what happens to carbon as it moves through a landscape. New research suggests that the more lake-rich a network ...
