- A research group has fabricated a highly transparent solar cell with a 2D atomic sheet. These near-invisible solar cells achieved an average visible transparency of 79%, meaning they can, in theory, be placed everywhere - building windows, the front panel of cars, and even human skin. https://www.tohoku.ac.jp/en/press/transparent_solar_cell_2d_atomic_sheet.html 1219 comments science
- Researchers have discovered electrical wave patterns in the brain related to social behavior in mice.
