Rhythms produced by the brain can reliably be used to predict how sensitive we are to pain, new research shows. The living brain is constantly producing regular rhythmic patterns of activity, which ...

Astronomers are on the verge of unlocking an entirely new way to observe the universe. Since the first detection of gravitational waves in October 2015, scientists have been listening in to these ...

The human brain can be primed to learn more than three times faster, simply by flashing a light at its individual alpha brainwave frequency for 1.5 seconds, suggests a fascinating new neuroplasticity ...

The recent detection of gravitational waves by the Laser Interferometer Gravitational-Wave Observatory (LIGO) came from two black holes, each about 30 times the mass of our sun, merging into one.

Here is a simple frequency doubler circuit that produces a square wave output with a precise 50 percent duty cycle. There are similar circuits in the literature [References 1, 2, 3] which require ...

Whenever I find myself harboring a constantly nagging thought, I know I will eventually have to get busy and find a way to put it to rest. When I read EDN’s Design Ideas, I look for the range of ...
