Computer simulations of electrical charges sent to retinal implants based on fractal geometry have University of Oregon researchers moving forward with their eyes focused on biological testing. That is potential down-the-road good news for people facing vision loss from retinal diseases, such as macular degeneration that, alone, incurs costs exceeding $340 billion globally, according to the Brightfocus Foundation.

University of Oregon chemists have synthesised a stable and long-lasting carbon-based molecule that, they say, potentially could be applicable in solar cells and electronic devices. The molecule changes its bonding patterns to a magnetic biradical state when heated; it then returns to a fully bonded non-magnetic closed state at room temperature. That transition, they report, can be done repeatedly without decomposition. It remains stable in the p...
