Tiny, individual, flexible ribbons of crystalline phosphorus have been made by UCL researchers in a world first, and they could revolutionise electronics and fast-charging battery technology.

Since the isolation of 2D phosphorene, which is the phosphorus equivalent of graphene, in 2014, more than 100 theoretical studies have predicted that new and exciting properties could emerge by producing narrow ‘ribbons’ of this material. These properties could be extremely valuable to a range of industries.

In a study published today in Nature, researchers from UCL, the University of Bristol, Virginia Commonwealth and University and École Polytechnique Fédérale de Lausanne, describe how they formed quantities of high-quality ribbons ...

Are Brown Dwarfs Failed Stars or Super-planets?

Artist rendering of a brown dwarf. They are more massive and hotter than planets but lack the nuclear fusion in their core as in normal stars. Two such “failed” stars were detected orbiting the star ? Ophiuchi. They were probably formed in the earlier protoplanetary disk of the star.

Astronomers find first signs they can also form like a planet. Brown dwarfs fill the “gap” between stars and the much smaller planets – two very different types of astronomical objects. But how they originate has yet to be fully explained. Astronomers from Heidelberg University may now be able to answer that question...

CRISPR-based ‘allelic drive’ allows Genetic Editing with Selective Precision and Broad Implications

Left panel: Gene-drive is mediated by a guide RNA (gRNA) that cuts at the exact site (scissors) where the gene-drive element (blue box: Cas9 gene; yellow box: gRNA) is inserted into the genome, resulting in full gene-drive element copying. Right panel: The new allelic drive is accomplished by the addition of a second gRNA (blue box) to a gene drive element that preferentially cuts a detrimental allele (scissors), but not the beneficial allele, resulting in beneficial allele copying.

Scientists developed a new version of a gene drive that allows the spread of specific, favorable genetic variants, also known as ‘alleles,’ throughout a population...

Meet Blue, the Low-cost, human-friendly Robot designed for AI

Blue the robot’s arms – about the size of a human bodybuilder’s — were designed to take advantage of recent advances in artificial intelligence to master intricate, human-centered tasks, like folding towels.

Blue’s creators hope the new robot will accelerate the development of robotics for the home. Researchers have created a new low-cost, human friendly robot named Blue, designed to use recent advances in artificial intelligence and deep reinforcement learning to master intricate human tasks, all while remaining affordable and safe enough that every AI researcher could have one. The team hopes Blue will accelerate the development of robotics for the home.

Robots may have a knack for super-human strength and precision, but they still struggle with some basic h...
