Tornadoes do occur in the Southern Hemisphere, albeit at a greatly reduced frequency than in the Northern Hemisphere, primarily because it includes the U.S., which hosts about 75 percent of the ...

Controlling the rotation of this molecule could lead to new technologies for microelectronics, quantum computing and more. You can easily rotate a baseball in your hand by twisting your fingers. But ...

Polarized light waves spin clockwise or counterclockwise as they travel, with one direction behaving differently than the other as it interacts with molecules. This directionality, called chirality or ...

We have all been taught in school that planets revolve in the same direction as the Earth, i.e., in the counterclockwise direction. However, the universe never ceases to amaze us with its unexpected ...
