because the same thing happens to bees. Researchers found that worker bees who care for the brood

get less sleep than their sisters, because bee babies produce chemicals that keep their caretakers

awake. The findings appear in the journal, current biology.

It seems that all animals sleep, including the birds and the bees.

Yet this daily phenomenon still remains blanketed in mystery.

The exact function of sleep is still an enigma, but we know that

reduced or sleep loss is associated with reduced

performance, health and survival. Mosheh Nagari was a postdoc at the Hebrew University of

Jerusalem when he started studying sleep. In particular, he was curious about how animals can

sometimes sacrifice Shadai when they've got important

work to do, especially moms tending to their young. Killer whale mothers, for example, follow their

calves for the first few weeks postpartum, and hardly ever sleep in this time for several weeks.
