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.
Researchers discover that a spot of molecular glue and a timely twist help a bacterial enzyme convert carbon dioxide into carbon compounds 20 times faster than plant enzymes do during photosynthesis. The results stand to accelerate progress toward converting carbon...
After almost two decades of synchrotron experiments, Caltech scientists have captured a clear picture of a cell’s nuclear pores, which are the doors and windows through which critical material in your body flows in and out of the cell’s nucleus...
