Electrons may undergo fission in liquid helium at temperatures near absolute zero, violating the long-held notion that elementary particles cannot be broken into two pieces. Experimental evidence supports this theory, which suggests that light can cause an electron's bubble to divide into smaller bubbles.
Physicists at the University of Illinois have made new measurements that provide information about how different flavors of quarks in a proton generate its magnetic moment. The results suggest that the contribution from the strange quark is significantly positive, contrary to most theoretical models.
A Duke study reveals that the pressures under poured sandpiles are highest at their peripheries due to unbalanced distributions of stresses. In contrast, showered sand piles concentrate stresses at their centers like medieval cathedrals' flying buttresses. This research has practical importance for structures prone to self-destruction.
The Williams College research team observed a two-and-a-half-minute period of totality in a clear sky, collecting fabulous scientific data that will keep researchers busy for years.
