The following news item

concerns the KaiC protein, which encodes the 24 hour length of the day, thus
facilitating the circadian rhythm.

Unfortunately, they referred to the length of the day as "Earth's daily rotation
period", which will only serve to prolong the confusion exemplified by a

Research where participants are denied visual stimulus for daylight hours often show very wayward timekeeping over extended periods.

Dare one suggest that the educationally-challenged miscreant, to whom you may be referring, may actually be a cough caveman?

Tests done in the 40's showed that humans can't adapt to a non-24hour day once they reach a certain age. Younger people are able to adapt to a different day length.
