Presented by Yijin Liu. In batteries, energy is stored in tiny particles within the electrodes that individually breathe in and out and chemically evolve as the battery is charged and discharged.
Presented by Arianna Gleason. When and where life originated on Earth – and if, or where, life exists elsewhere in the cosmos – are some of the biggest scientific questions of our time.
Petroglyphs are carved in a material called rock varnish, the origins of which have been debated for years. Now, scientists argue it’s the result of bacteria and an adaptation that protects them from the desert sun’s harsh rays.
Presented by Diana Gamzina. In particle accelerators, electrons are pushed to extreme energies by electromagnetic fields that oscillate inside evacuated metal cavities. Those cavities are usually made of copper.
The lab’s X-ray laser recently joined other facilities in making remote science possible from any corner of the world, a trend that will likely continue into the future.
A cellphone-sized device automatically adjusts a home's power use up or down to save the consumer money and increase the resiliency of the electric grid.
