Recent science news on Science Island. Read more details here: https://scienceisland.org/ 1 - Special Relativity Aces Time Trial Physicists have verified a key prediction of Albert Einstein’s special theory of relativity with unprecedented accuracy. Experiments at a particle accelerator in Germany confirm that time moves slower for a moving clock than for a stationary one. 2 - Superheavy Element and Carbon Atom Bonded for First Time A chemical bond between a superheavy element and a carbon atom has been established for the first time. This research opens new vistas for studying the effects of Einstein’s relativity on the structure of the periodic table. 3 - Solar-Cell Efficiency Improved with New Polymer Devices New light has been shed on solar power generation using devices made with polymers. Researchers identified a new polymer — a type of large molecule that forms plastics and other familiar materials — which improved the efficiency of solar cells. The group also determined the method by which the polymer improved the cells’ efficiency. The polymer allowed electrical charges to move more easily throughout the cell, boosting the production of electricity — a mechanism never before demonstrated in such devices. 4 - Computers 1,000 Times Faster? Quick-Change Materials Break Silicon Speed Limit for Computers The present size and speed limitations of computer processors and memory could be overcome by replacing silicon with ‘phase-change materials’ (PCMs), which are capable of reversibly switching between two structural phases with different electrical states — one crystalline and conducting and the other glassy and insulating — in billionths of a second.
