Consumers are less forgiving of brand failures when algorithms are anthropomorphized, use machine learning, or are used for subjective or interactive tasks.

An individual human can maintain stable social relationships with about 150 people, not more. This is the proposition known as 'Dunbar's number' - that the architecture of the human brain sets an upper limit on our social lives. A new study indicates that a cognitive limit on human group sizes cannot be derived in this manner.

Researchers have identified a set of genes, called clock genes, that control circadian rhythms. But a more complicated gene network than previously known appears related to these rhythms. Scientists detail a statistical model they are using to help identify the genes involved in this network. With help from other disciplines, they hope to fully understand how these genes work together to make different people more productive at different times of day.
