Illustration of photoacoustic tomography New research demonstrates the use of a pulsed laser diode in photoacoustic tomography, a technique that uses light pulses to generate sound waves in a sample, which are then detected by an ultrasound detector and from which images can be produced computationally. Due to the higher pulse rate of...

Beam of light in sky above city A new approach to atmospheric monitoring measures laser backscatter range as a function of angle using the Scheimpflug principle, instead of the more common time of flight method known as Lidar, which means it can monitor a large volume of space all at once. Given the name SLidar, it was...

The era of quantum computers is one step closer as a result of research published in the current issue of the journal Science. The research team has devised and demonstrated a new way to pack a lot more quantum computing power into a much smaller space and with much greater control than ever before. .

Researchers from the University of Houston have reported a new technique to determine the chemical composition of materials using near-infrared light. The work could have a number of potential applications, including improving downhole drilling analysis in the oil and gas industry and broadening the spectrum of solar light that can be harvested and converted to electricity...

NASA has announced plans to extend operations of the famous space telescope for another five years, through to June 2021. That means it will still be on the job when its successor, the James Webb Space Telescope (JWST) launches in 2018, giving astronomers a dual view of the universe.

With a surface resembling that of plants, solar cells improve light-harvesting and thus generate more power. Scientists of KIT (Karlsruhe Institute of Technology) reproduced the epidermal cells of rose petals that have particularly good antireflection properties and integrated the transparent replicas into an organic solar cell. This resulted in a relative efficiency gain of twelve percent.

(University of Basel) Chemists from the universities of Basel and Zurich in Switzerland have come one step closer to generating energy from sunlight: for the first time, they were able to reproduce one of the crucial phases of natural photosynthesis with artificial molecules. Their results have been published by the journal Angewandte Chemie (international edition).
