Dark Matter Alternative Passes Big Test

Physics: Researchers pursuing an unconventional view of cosmology that dispenses with dark matter have developed a model that can match observations of the cosmic microwave background (CMB), the leftover glow of the big bang. This dark-matter-free model is an extension…

Exciting way to improve efficiencies of organic solar cells

Materials Today: Researchers at the University of California (UC) Santa Barbara and eight other institutions have identified a key mechanism responsible for the lower efficiencies of organic solar cells and have demonstrated a way this hurdle might be overcome. Their results,…

Stacking order in a 2D magnet produces Dirac magnons

Physics World: Three years ago, an international team of researchers observed something unexpected in a sample of chromium triiodide (CrI3): quasiparticles known as magnons appeared to be travelling along its edges, rather than moving through the sample’s bulk. This observation suggested…

Life beyond the Nobel: Andrea Ghez eyes up new research directions

Physics World: Physicists around the world are gearing up for tomorrow’s big reveal of who has won the 2021 Nobel Prize for Physics. Part of the prize’s appeal is that no-one – apart from the members of the Nobel Committee for…
