Interview with Takashi Tsuji, team leader of the Laboratory for Organ Regeneration at the RIKEN Center for Developmental Biology

Strong emotions plus non-REM sleep equals longer-lasting perceptual memories


Perceptual memories linked to positive emotions, such as joy or happiness, are strengthened during sleep, specifically during periods of deep non-REM sleep.

Summer fun: how plants beat the heat


Scientists have discovered a gene that allows plants to cope with extreme heat by changing the composition of chloroplast membranes.
