When atomic nuclei smash together at nearly the speed of light, they create the hottest fluid in the universe, but scientists may have overlooked one of its most important forces。 New simulations reveal that extreme acceleration builds up along the edges of quark-gluon plasma, helping drive its explosive expansion。 This acceleration may do far more
Millions of sperm do not always compete alone—some species send them into action as coordinated teams。 A sweeping evolutionary study found that this cooperation is widespread among arthropods and has repeatedly emerged and vanished over hundreds of millions of years。 The discovery challenges the classic “fastest sperm wins” story and could influenc
