Japanese researchers have significantly improved the performance of a gamma ray-imaging “Compton” camera. The new technology has potential applications in scientific research, medical treatment and environmental monitoring, as well as radioactive decontamination work.
Based on a high-sensitivity mobile gamma ray camera released by Hamamatsu Photonics in 2013, the new Compton camera incorporates high-accuracy, three-dimensional, gamma ray position measurement technology developed at Waseda University.

Led by Professor Jun Kataoka, the Waseda team improved the original camera’s resolution by about two times and enhanced its sensitivity by approximately 70%.
The new technology enables the smooth and accurate visualisation of gamma rays, which are invisible to the human eye, and could be used to help with the removal of radioactive substances from the Fukushima Daiichi nuclear accident.
The Waseda team is now working to make the detector even lighter and smaller: only 500 grams or less in weight and about 10 cubic centimetres in size.
Professor Kataoka plans to use the detector to advance
research on bio-function dynamics imaging and proton therapy.

In best circles: First integrated circuit from self-assembled polymer
19.02.2018 | Max-Planck-Institut für Polymerforschung
For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
Breakthrough provides a new concept of the design of molecular motors, sensors and electricity generators at nanoscale

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
