Breast CT Scanner Could Improve Cancer Screen Comfort

... looking to be more effective than traditional mammography at detecting breast masses. More work needs to be done to find microcalcifications, tiny specks of calcium which don't always mean cancer is present but bear checking, he added. Next, Boone hopes to use the breast CT scanner to guide intervent...

Stardust Brings Interstellar Dust

... see lots of impacts. There are big ones, there are small ones’, he said. According to Brownlee, there might be more than a million microscopic specks of dust embedded in Stardust's Aerogel collector. He said that Aerogel was a remarkable material that is as much as 99.9% empty space, and it greatly ...
