A tabletop instrument sensitive enough to measure a twist smaller than a trillionth of a degree has just become the world’s most powerful direct probe of ultralight dark matter. In a study released in ...

Researchers at the University of California, Santa Cruz have trained lab-grown clusters of mouse brain cells to balance a virtual pole on a moving cart, marking what the team calls the first ...

Imagine balancing a ruler vertically in the palm of your hand: you have to constantly pay attention to the angle of the ruler and make many small adjustments to make sure it doesn't fall over. It ...
