This easy science activity demonstrates the difference in density between hot and cold water. It can be a bit messy so you may want to try this outside. We're joined by BASF employee, Casey, and his ...

MIT researchers found a way to measure cell density quickly and accurately -- measuring up to 30,000 cells in a single hour. They also showed density changes could be used to make useful predictions, ...

By developing a new theoretical relation describing just how compact neutron stars — which are the remnants of massive stars ...

Flotation is, well, a “simple” question of physics (an idea that’s flummoxed scores of physics students for centuries). Bowling balls seem heavy, and they are compared to other sports balls, which may ...

Black holes are some of the most intriguing objects in the universe. They have tremendous mass and density, so nothing can escape once it has fallen in, not even light. But how do black holes form? In ...

Students will be able to explain that the density of a substance has to do with how heavy it is compared to the size of the object. Students will also be able to explain that density is a ...

WASHINGTON ― The U.S. can reap important benefits from fundamental research in high energy density science by renewing investment in its flagship facilities; improving workforce climate with ...
