Join me in this feature-length venture into the belly of the beast, from the storage casks to the open reactor itself.
NASA plans to send a new, light-sensitive camera to explore the moon’s most shadowed regions. ShadowCam will look for evidence of water ice in the permanently shadowed regions of the moon.
Lunar areas that never receive sunlight – frigid craters and mountain shadows – could conceal a treasure trove of water ice, especially near the poles.
In one five-year period, college athletes suffered more than 10,000 concussions — one-third of them while playing football. But an unusual team-up has recently brought a new, biomarker-based concussion test one step closer.
