Researchers from Denis Diderot University in Paris, the French National Centre for Scientific Research (CNRS) and the University of Leeds, have produced T-ray 'pulses' from a quantum cascade laser. This is the first time that such a high-powered source of terahertz rays (T-rays) has been made to emit separate 'packets' of terahertz radiation, rather than one continuous T-ray beam. Read more
New T-ray device to explore cosmic radiation A miniscule sensor could lead to a better understanding of the formation of new stars, planets, and the hole in the ozone layer by studying an obscure wavelength of radiation. Scientists at Delft University of Technology in the Netherlands have built the pinpoint-size detector, which senses the least explored region of the electromagnetic spectrum, to measure molecules and gases in planet's atmospheres.
