Humans may not be as hardwired for violence as we thoughtA study comparing 100 primate species, including humans, suggests that everyday aggression and lethal violence did not evolve as part of the same simple behavioral spectrum. Species that frequently fight or show mild aggression are not necessarily more likely to kill rivals, while extreme acts such as infanticide and lethal attacks appear to follow their own evolutionary patterns.

Physicists just saw quarks make waves in the Big Bang’s primordial soupPhysicists at CERN’s Large Hadron Collider have captured the clearest evidence yet that quark-gluon plasma, the scorching-hot matter that filled the newborn universe, behaves like a true liquid. By tracking individual quarks as they blasted through the plasma, researchers saw them leave behind ripples, splashes, and swirling wakes much like a duck moving through water. The finding suggests this primordial “soup” is so dense that it can slow speeding quarks and respond collectively as a fluid.
