Better sensing through empty receptors
Geplaatst op 26 september 2009 - 11:08
Cells may benefit by paying attention to sensors that are still open for business.
A new model finds that, contrary to conventional wisdom, sensors on the outside of a cell that have not yet detected a chemical signal may be more useful than those that have already detected the signal, a study set to appear in Physical Review Letters suggests. By reconsidering how a cell sorts information, Ned Wingreen of Princeton University and Robert Endres of Imperial College London found that these unbound sensors can collectively provide a clearer view of the environment.
"Invisible Pink Unicorns are beings of great spiritual power. We know this because they are capable of being invisible and pink at the same time. Like all religions, the Faith of the Invisible Pink Unicorns is based upon both logic and faith. We have faith that they are pink; we logically know that they are invisible because we can't see them."
