Energy Cascades in Quasicrystals Trigger an Avalanche of Discovery
Scientists at the Argonne National Laboratory looked at quasicrystals – materials with geometrically organized, but never repeating atomic structures – and unexpectedly found redistribution of energy occurs as a chain reaction would in the forked branches of a lightning strike.

Dark Energy Survey (DES) scientists recently reported the discovery of a potential dwarf planet located 92 times farther from the sun than the Earth is, more than twice as distant as Pluto. The new dwarf planet was discovered using the Dark Energy Camera, a scientific instrument built at Fermilab to probe the mystery of dark energy.
