  • Scientists discover that active particles take a pass on Newton's Second Law.
  • Active particles exist in a "swirlonic" state of matter.
  • Swirlonic behavior explains some of the more dazzling natural phenomena such as starling swarms and shape-shifting schools of fish.

  • Scientists have found that cultures of embryonic brain cells mature at the same rate as a 20-month-old infant's.
  • Researchers have looked to such cell structures, called "organoids," as potential models for understanding the human body's biological mechanisms.
  • Their study validates the use of lab-dish organoids for research.
