Hurricanes and low pressure systems do spin counter-clockwise in the northern hemisphere. Tornadoes usually do, though not always. The behavior of the intense thundershowers that produce tornadoes ...

Scientists have uncovered a new explanation for how swimming bacteria change direction, providing fresh insight into one of ...

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 ...

Researchers have unseated a previous theory for the mechanism underlying bacterial flagella movement, changing our ...

Scientists reveal how bacteria switch direction through a microscopic tug-of-war inside their motors, driven by energy and ...

Usually, tornadoes in the U.S. rotate counterclockwise. Coriolis force, imparted due to the Earth’s rotation, causes air around low centers to circulate counterclockwise in the northern hemisphere.
