Asteroid impacts pose such a huge threat to humanity that scientists are considering “backing-up” life on Earth in secure bunkers, according to an Australian robotics professor.

Hundreds of built and proposed hydroelectric dams may significantly harm life in and around the Amazon by trapping the flow of rich nutrients and modifying the climate from Central America to the Gulf of Mexico.

Alien species are a global problem, but they’re a particular headache in certain hotspots of the world.

At the annual meeting of the Geological Society of America, Smithsonian paleontologist Doug Erwin took the podium to address a ballroom full of geologists on the dynamics of mass extinctions and power grid failures—which, he claimed, unfold in the same way.

Scientists in Australia have developed a solar paint capable of pulling water molecules from the air and splitting them into oxygen and hydrogen, the latter of which can be stored for use as fuel.

The dust surrounding active, ravenous black holes is much more compact than previously thought, it has been found by researchers at the University of Texas-San Antonio using observations from NASA’s Stratospheric Observatory for Infrared Astronomy, SOFIA.

As the universe expanded after the Big Bang, galaxies spread out too, and many of them grouped together in gigantic clusters that can be thought of as “urban centers” of the cosmos.
