Scientists used fluorescence correlation spectroscopy to investigate the processes at the surface of growing crystals. They found that when single tetragonal crystals formed, there was no concentration gradient between the solution and the crystal surface. However, in formation of clumps of needle-like branched crystals, called spherul...
Researchers found that people who watched videos of someone else performing simple actions were more likely to falsely remember doing the same action themselves two weeks later. This phenomenon, known as observation inflation, may be due to internal simulation of what others are doing while observing them.
