New model of quark-gluon plasma solves a long-standing discrepancy between theory and data

Research in fundamental science has revealed the existence of quark-gluon plasma (QGP)—a newly identified state of matter—as the constituent of the early universe. Known to have existed a microsecond after the Big Bang, the ...

The Kibble-Zurek mechanism for nonequilibrium phase transitions

The Kibble-Zurek (KZ) mechanism, confirmed experimentally only for equilibrium phase transitions, is also applicable for non-equilibrium phase transitions, as is now shown by Tokyo Tech researchers in a new study. The KZ ...

A better way to tell which species are vulnerable

Wildfires, floods, pollution, and overfishing are among the many disruptions that can change the balance of ecosystems, sometimes endangering the future of entire species. But evaluating these ecosystems to determine which ...

Enzymatic reactions: Researchers reveal a regulatory mechanism by which life controls and organizes itself

Inside cells, molecular droplets form defined compartments for chemical reactions. Not only sticky interactions between molecules, but also dynamic reactions can form such droplets, as was found by researchers from the Max ...

Speed limits for quantum phenomena have been extended to macro-sized objects

An expression for the maximum speed at which changes in macroscopic systems can occur has been derived by a theoretical physicist at RIKEN. This will deepen our understanding of quantum phenomena in systems that are not in ...

Scientists capture first-ever view of a hidden quantum phase in a 2D crystal

The development of high-speed strobe-flash photography in the 1960s by the late MIT professor Harold "Doc" Edgerton allowed us to visualize events too fast for the eye—a bullet piercing an apple, or a droplet hitting a pool ...
