The handling of non-spherical micron-sized objects is a challenge for the manufacturing industry and for the wider exploitation of nanomaterials. Current manipulation techniques consist of pick-and-place machines used to place microelectronic components onto circuit boards, and optical methods that use laser radiation to manipulate objects. Pick-and-place methods are unsuitable for objects smaller than 100 microns because electrostatic and Van der Waals attraction prevents their release.

Dr Roger Johnson has been awarded the BTM Willis prize for his work on the understanding of magnetic and magnetoelectric phenomena achieved through state-of-the-art structural studies of complex crystalline solids. The prize is jointly awarded by the Institute of Physics and Royal Society of Chemistry Neutron Scattering Groups to an early career researcher. Dr Johnson is a Royal Society University Research Fellow in the Quantum Materials section of the sub-department of Condensed Matter Physics.

The recent development of gene editing using biological system CRISPR, creates the prospect of dramatic developments in medicine for gene repair and cancer therapy. The CRISPR/Cas9 system allows targeted DNA cleavage and hence editing of the genome. However, unwanted DNA cuts, resulting from non-specific delivery to off-target cells, could promote tumorigenesis. Cell-specific activation of CRISPR/Cas9 is essential to avoid this problem.

The technology available to licence is a new technique for using higher order Hermite-Gaus (HG) modes to increase the channel capacity in telecommunication networks via HG mode selective multiplexing. The bandwidth of telecommunication networks can consequently be brought up to the theoretical maximum for a particular time-frequency resource.
As the device proposed operates noise-free, the invention is expected to be of use in applications.

Astronomers have discovered rapidly swinging jets coming from a black hole almost 8000 light-years from Earth.
Published today in the journal Nature, the research shows jets from V404 Cygni’s black hole behaving in a way never seen before on such short timescales.
The jets appear to be rapidly rotating with high-speed clouds of plasma—potentially just minutes apart—shooting out of the black hole.
