Quantum computer simulates matter “popping into existence”

Scientists recreated a particle-forming process linked to the extreme physics of the early universe using a 13-ion quantum simulator. The breakthrough suggests quantum computers could eventually help researchers investigate how matter formed and evolved after the Big Bang.

Earth is tearing apart beneath the Pacific Northwest

Scientists have captured a subduction zone off Vancouver Island in the process of tearing itself apart, revealing that these massive tectonic systems may die piece by piece rather than all at once. The discovery could help explain ancient plate fragments, volcanic activity, and h

The Solar System chose fire over ice from the very beginning

Ancient iron meteorites reveal that some of the Solar System’s first solid bodies were built mostly from tiny heat-forged rock beads called chondrules, while water-rich dust was largely excluded. The finding pushes this selective planet-building process back to within the Solar S

A new process turns plastic waste into gasoline and diesel fuel

Scientists at Oak Ridge National Laboratory have developed a surprisingly simple way to turn polyethylene, the common plastic used in shopping bags and cutting boards, into gasoline and diesel-like fuels. The process uses inexpensive aluminum-based molten salts to break long plas
