As sesquicentennial occurs, debate on arrangement of periodic table continues

Eric Scerri, a UCLA chemistry lecturer, has written at least six books discussing the orientation of the periodic table. His office is cluttered with posters and three-dimensional models of different periodic systems. Read more...

UCLA researchers help develop new, more durable aerogel insulator

UCLA researchers invented a new aerogel that that can withstand quick temperature changes, offering a better way to insulate spacecrafts traveling to planets with extreme conditions. Read more...

Researchers develop more accurate method of determining age of death

UCLA researchers have developed a new tool to predict when someone will die, but don’t start planning your funeral yet. In a study published last month in the journal Aging, researchers in the lab of Steve Horvath, a professor of human genetics and biostatistics, developed a new method of predicting the population lifespans that is 14 percent more accurate than previous methods.
