Micrometeorites are thought to shower down on planets throughout the universe, so the discovery that they help protocells form could tell us something about the chances of life elsewhere Micrometeorites are thought to shower down on planets throughout the universe, so the discovery that they help protocells form could tell us something about the chances …

Scientists have discovered a stealthy mechanism that cytomegalovirus (CMV)—the leading infectious cause of birth defects in the U.S.—uses to infiltrate blood vessel cells while evading immune detection. The virus forms a hidden protein complex that acts like a molecular “backdoor,” allowing it to bypass the immune system’s defenses. This newly identified pathway may explain why …
This virus infects millions—and we just discovered its secret weapon Read More »
Physicists at the University of Colorado Boulder have created a groundbreaking quantum device that can measure 3D acceleration using ultracold atoms, something once thought nearly impossible. By chilling rubidium atoms to near absolute zero and splitting them into quantum superpositions, the team has built a compact atom interferometer guided by AI to decode acceleration patterns. …
