New force…
Everything in our Universe is held together or pushed apart by four fundamental forces: gravity, electromagnetism, and two nuclear interactions. Physicists now think they've spotted the actions of a fifth physical force emerging from a helium atom. It's not the first time researchers claim to have caught a glimpse of it, either. A few years…

Benzene. Dimensions. Reality.
Nearly 200 years after the molecule was discovered by Michael Faraday, researchers have finally revealed the complex electronic structure of benzene. This not only settles a debate that has been raging since the 1930s, this step has important implications for the future development of opto-electronic materials, many of which are built on benzenes. The atomic…

Limits of measurements… Limits of out self…
The limits of classical measurements of mechanical motion have been pushed beyond expectations in recent years. But the sensitivity that we can achieve using purely conventional means is limited. For example, Heisenberg's uncertainty principle in quantum mechanics implies the presence of "measurement backaction": the exact knowledge of the location of a particle invariably destroys any…

Touching. Not-touching. Sensing.
Through the crafty use of magnetic fields, scientists have developed the first electronic sensor that can simultaneously process both touchless and tactile stimuli. Prior attempts have so far failed to combine these functions on a single device due to overlapping signals of the various stimuli. As the sensor is readily applied to the human skin,…

Faster than light… So?
Faster-than-light speeds could be why gamma-ray bursts seem to go backwards in time. (1) Amazing. Isn’t it? But wait a minute. If gamma rays can do that, then why are we so keen on doing the same? And what is more… Why are we so keen on doing something that common matter can do? Do…
