'One Plant Health Concept' connects tradition and technology to address plant diseases in Africa

Eight CubeSats and one payload supported by the European Space Agency (ESA) have reached orbit, where they will demonstrate various applications aimed at improving how data is sent around and processed. Thanks to these demonstrations, practical and—sometimes—even life-saving data enabled from space will move more efficiently and reach the right actors on time in the future.

The ice giant Uranus is one of the most fascinating objects in the solar system, with its sideways rotation, intricate ring system, and unique family of moons. However, it is also one of the least explored objects in the solar system, owing to its extreme distance from the sun. With NASA's Voyager 2 spacecraft remaining as the only spacecraft to visit Uranus, scientists continue to design and envision mission concepts for returning to explore Uranus and its icy secrets.

Most predators slow down when ocean temperatures shift. Great hammerhead sharks don't—not significantly anyway. These ocean predators are masters of the "thermal hustle," maintaining peak hunting performance across a surprisingly wide range of ocean temperatures between winter and summer months, according to new research published this week in Journal of Experimental Biology.

In the medieval European imagination, racial difference was often highly polarized. Black people were perceived either as exotic status symbols—including saints and wealthy rulers such as the Queen of Sheba—or as subjugated figures, considered inferior to white Christians.
