Watery planets orbiting dead stars may be good candidates for studying life — if they can survive long enough

The small footprint and dim light of white dwarfs, remnants of stars that have burned through their fuel, may make excellent backdrops for studying planets with enough water to harbor life. The trick is spotting the shadow of a planet against a former star that has withered to a fraction of its size and finding

Technologies enable 3D imaging of whole human brain hemispheres at subcellular resolution

A suite of three innovations enables high-resolution, high-throughput imaging of human brain tissue at a full range of scales and mapping connectivity of neurons at single cell resolution. To demonstrate the advance, researchers compared a brain region in an Alzheimer’s and a control sample.
