Twisted bilayer graphene is a carbon-based, two-dimensional (2D) material comprising two graphene layers. Although many scientists have recently started exploring its potential for superconductivity and magnetism, so far, ...
Magic-angle twisted bilayer graphene is a material made of two sheets of graphene placed on top of each other, with one sheet twisted at precisely 1.05 degrees with respect to the other. This material has been found to be ...
(Phys.org) —Light striking the retina in the back of the eye is the first major step in the vision process. But when the photoreceptors in the retina degenerate, as occurs in macular degeneration, the retina no longer responds ...
(Phys.org) —If you asked a biologist what any given cell is going to do next, they might ask you first to tell them its electrical potential, oxygenation, pH, osmolarity or glucose concentration. Depending on how finely-scaled ...
Glassfrogs make themselves transparent while they rest by taking red blood cells from circulation and concealing them in their livers. A multi-disciplinary team of biologists and biomedical engineers has shown how these frogs ...

In 2016, physicist J.C. Séamus Davis discovered an elusive state of quantum matter in the cuprates, which are copper oxide materials laced with other atoms. That launched a new sub-field in the study of quantum materials.

Using the AstroSat spacecraft, Indian astronomers have performed an imaging and spectroscopic study of the Fornax A galaxy. Results of the study, published January 13 on the arXiv preprint server, provide more clues on the ...
New periodic structures known as moiré lattices can be observed in two-dimensional (2-D) heterostructures containing layers with slightly different lattice vectors, which can in turn support new topological phenomena. It ...
X-rays with excellent penetration power and high chemical sensitivity are suited to understand heterogeneous materials. In a new report on Science Advances, A. Pattammattel, and a team of scientists at the National Synchrotron ...
Using ESO's Very Large Telescope (VLT), astronomers have probed the chemical composition of a nearby metal-poor star-forming dwarf galaxy known as JKB 18. Results of the new observations indicate that the galaxy is chemically ...
