The Science Siblings, Adam and Paige Jacobson, recruited 4-year-old Tukker and 2-year-old Jayger for a density experiment. They tested whether fruits and veggies float or sink in a bowl of water.

Scientists at China’s EAST tokamak have achieved plasma densities beyond long-standing limits using plasma-wall self-organisation.

Experiments at China's Experimental Advanced Superconducting Tokamak have confirmed the existence of "a density-free region" of the tokamak, finding a method to break through the density limit and ...
