History affects superfluid’s flow, study shows
The speed to stop the stirring motion can be slower than what was need to set the fluid spinning in the first place, which shows that what happens to the current state of the superatom depends on what it has already experienced.

Making it work, on paper and just maybe in practice
Last spring, Science News reported on the lack of progress by the main U.S. nuclear fusion effort. As the researchers still contend, laser-initiated fusion should work. It works on paper. But in practice, even a set of extremely powerful lasers failed to trigger the fusion of hydrogen nuclei and the concomitant chain reaction and release of net energy expected.
