An international team of astronomers, including many from the UK, has revealed an ‘astonishing’ overabundance of massive stars in a neighbouring galaxy.

The discovery, made in the gigantic star-forming region 30 Doradus in the Large Magellanic Cloud galaxy, has ‘far-reaching’ consequences for our understanding of how stars transformed the pristine Universe into the one we live in today.

Programmable photonic circuits that can implement linear transformation between any number of input and output optical channels are used both for quantum computation in quantum optics and for signal processing in telecommunications. These “universal multiport interferometers” can be built using meshes of reconfigurable beam splitters, for example on an integrated photonic platform.

Researchers at the University of Oxford have demonstrated, for the first time, how to use molecules to manipulate the surface of a ‘topological insulator’, an exotic material with unusual electronic properties. Understanding and manipulating these properties is a notable step towards the innovative information transfer and storage promised by ‘spintronics’.

Radioactivity detectors are widely used in society to ensure safe levels of human exposure to potentially dangerous radiation are maintained. Measuring radiation in the atmosphere is also of great interest to researchers as its effects on the lower atmosphere are currently poorly understood.

Signal couplers allow signals from two transmission lines to be combined and/or split, and can be used in a variety of applications including power distribution networks, sensor arrays, and astronomical instrumentation. Conventional couplers have both transmission lines, which carry the signal, running in parallel to each other, which makes them unsuitable for circuits that require signal path crossing or bypassing, particularly in applications in a linear array. Traditionally this is overcome by using cross-guide coupler, additional cabling or series of optical free-space beam splitters.

Researchers from the University of Oxford have for the first time mapped the magnetic interactions of an artificial garnet known as YIG (yttrium iron garnet). This understanding could pave the way for the ‘magnonics’ revolution, which offers an entirely new way to transfer data.
