COMPUTER SIMULATION DEMONSTRATES “BREATHING” ENZYME ACTION

COMPUTER SIMULATION DEMONSTRATES “BREATHING” ENZYME ACTION Greg Lester Using powerful supercomputers, NSF-supported researchers have unlocked the mystery surrounding one of the fastest, most efficient enzymes in the human body. Acetylcholinesterase (AChE) works to instantly stop transmissions from one nerve cell to the next nerve or muscle cell. AChE catalyzes the chemical reaction that breaks up […]

Model of Earth’s Interior Predicts Size and Shape of Tectonic Plates

Model of Earth’s Interior Predicts Size and Shape of Tectonic Plates Cheryl Dybas With a simple assumption and lots of supercomputer time, two National Science Foundation (NSF)-supported geophysicists have solved a long-standing problem in geology — why the jigsaw puzzle of crustal plates on the Earth’s surface looks the way it does. The problem, which […]

Airborne Sea Salt Particles Influence Air Pollution

Airborne Sea Salt Particles Influence Air Pollution Cheryl Dybas NSF-supported scientists have shown that sea salt particles — a common ingredient of coastal and ocean air — undergo a previously unrecognized chemical reaction in daylight to release chlorine molecules, which can influence ozone levels in the lower atmosphere. Researchers Barbara Finlayson-Pitts and Donald Dabdub of […]
