Purdue researchers have isolated the protein that controls the body's clock -- by fuxoring with it, they hypothesise that they can induce "days" that are longer or shorter than 24h in humans and other organisms.
To confirm that the protein was responsible not just for regulating growth but for all activities set by the biological clock, Pin-Ju Chueh, then a microbiology graduate student in Dorothy Morre's lab, isolated the gene which produced the protein within cells. The team then cloned the protein and altered it in ways that produced different period lengths.
"We found that we could produce clocks with cycles of between 22 and 42 minutes," James Morre said. "The 'day' which the cell experienced was precisely 60 times the period length of the protein's cycle. We even found that feeding cells heavy water gave them a 27-minute cycle of growth and rest, so that old piece of information served to confirm our theory."

The internet service provider has often complained (such as when lobbying against net neutrality) that it must impose limits on service to prevent network congestion. The argument suggests that these measures are […]
