On 10/3/19 at 11:00 AM EDTA study has revealed that bumble bees appear to give up sleep in order to care for their hive's young, even if the offspring isn't their own.
. But sometimes skipping shut-eye can be beneficial if it frees up time for an animal to migrate, gather food, or stay safe from predators.For instance, as bleary-eyed parents can attest, human mothers sleep less and wake intermittently when they are near their babies, while rat mothers are woken up during the period when their pups drink their milk. These examples of deprivation are in response to a baby's behavior.
In contrast, the control bees who were not exposed to the brood were found to be more active in the day compared with the carer bees. What remains unclear is why the brood needed round-the-clock care. The scientists surmised this could help speed up growth, and enable workers to regulate the brood's temperature.Co-author Guy Bloch, professor of biology at The Hebrew University of Jerusalem told:"We spend much of our time asleep, but still we do not know what is the biological function of sleep.
