Scientists have achieved a breakthrough in creating an electrically driven organic semiconductor laser, paving the way for advanced and versatile laser applications.

Researchers at the University of St. Andrews are leading a significant breakthrough in a decades-long challenge to develop compact laser technology.

New research has unveiled an advancement in Light Detection and Ranging (LIDAR) technology, offering unparalleled sensitivity and precision in measuring the distance of remote objects.

This research, published in Physical Review Letters, is a result of a collaboration between the group of Professor Yoon-Ho Kim at POSTECH in South Korea, and the Quantum Science and Technology Hub at the University of Portsmouth.

Coherent LIDAR has long been a cornerstone in distance measurement, but its capabilities have been restrained by the time of the light source. In a pioneering move, researchers have introduced two-photon LIDAR, eliminating the range limitations imposed by coherence time, to achieve accurate and precise ranging of a remote object situated far beyond the coherence time dictated by the spectral bandwidth of the light source.

The advancement of higher cognitive abilities in humans is predominantly associated with the growth of the neocortex, a brain area key to conscious thinking, movement, and sensory perception. Researchers are increasingly realizing, however, that the “little brain” or cerebellum also expanded during evolution and probably contributes to the capacities unique to humans, explains Prof. Henrik Kaessmann from the Center for Molecular Biology of Heidelberg University.

His research team has – together with Prof. Dr Stefan Pfister from the Hopp Children’s Cancer Center Heidelberg – generated comprehensive genetic maps of the development of cells in the cerebella of humans, mice, and opossums. Comparisons of these data reveal both ancestral and species-specific cellular and molecular characteristics of cerebellum development spanning over 160 million years of mammalian evolution.
