If the biological “clocks” – the genetic networks controlling circadian rhythms – present in virtually every cell of our body ticked out loud, would their sound amount to a chaotic cacophony or a harmonious hum?
Until several years ago, scientists thought that the master clock in the brain brought into line all the sections of the orchestra, from the head on down. In the past few years, however, studies have shown that clocks in other organs are sometimes out of step with the one in the brain, but these clocks were collectively viewed as a uniform group. A new Weizmann Institute of Science study reveals that there are “cross-rhythms” even within that group.

REHOVOT, ISRAEL – May 25 2022 – Our family origins tend to shape our future in many ways. A Weizmann Institute of Science study, published today in Nature, found that the same holds true for blood vessels. The researchers discovered blood vessels forming from unexpected progenitors and went on to show that this unusual origin determines the vessels’ future function.
“We found that blood vessels must derive from the right source in order to function properly – it’s as if they remember where they came from,” says team leader Prof. Karina Yaniv.
