Researchers have shown that a laser-generated microplasma in air can be used as a source of broadband terahertz radiation. They demonstrate that an approach for generating terahertz waves using intense laser pulses in air can be done with much lower power lasers, a major challenge until now. They have exploited the underlying physics to reduce the necessary laser power for plasma generation.
Thermal imaging, microscopy and ultra-trace sensing could take a quantum leap with a new technique. Scientists used quantum correlated beams of light to overcome the fundamental detection limit of microcantilever-based sensors caused by intensity fluctuations.
The power of invisibility has long fascinated man and inspired the works of many great authors and philosophers. A team of neuroscientists now reports a perceptual illusion of having an invisible body, and show that the feeling of invisibility changes our physical stress response in challenging social situations.
Do you have a fascination with Einstein's theory of relativity? What I mean is, do you find yourself fascinated by the weird predictions of this theory and would like to get to the bottom of it once and for all? While relativity ...
