UCLA researchers have discovered that tiny crystals called otoliths—necessary parts of a properly functioning inner ear—form not as the direct result of a gene product, but rather as the result of the physical, swaying motion of hair-like cilia during development.

According to certain scientists, human activity that causes damage to the environment may interfere with the ongoing evolution of the earth.

Aided by a supercomputer, an international team of theoretical physicists has recently performed a massive computation that confirmed Einstein’s famous formula E=mc², which states that matter and energy interconvert. Their research appears in the November 21, 2008, edition of the journal Science.
