Holding information in mind may mean storing it among synapses

Researchers at MIT's Picower Institute found that the brain stores information in working memory by making short-lived changes in neural connections, contradicting the traditional idea of sustained neuronal activity. This new insight sheds light on the sophisticated flexibility of thought and its dynamic nature.

New study on the circadian clock of the fruit fly

Researchers discovered a point mutation in the fruit fly Drosophila melanogaster that leads to a temperature-dependent lengthening of circadian clock periods. The mutation affects the nuclear export signal of the PERIOD protein, resulting in its retention in the cell nucleus at higher temperatures.
