Dr.Back and his team have shown that during human brain development, thereis a critical time period when the cells (oligos or oligodendrocyteprogenitors) required to make myelin are easily killed...Circadian clock controls plant growth hormone
...ost plants and animals have an internal clock that allows them to match their activities to the time of day or season of the year. The circadian rhythms appear to act by "gating" the effect of auxin, the researchers said. In other words, the plant becomes more responsive to auxin at a certain time of day....New textbook illuminates the close links between evolutionary and molecular biology
