(PhysOrg.com) -- Many of the genes that regulate insulin also alter the timing of the circadian clock, a new study has found. http://www.physorg.com/news172409914.html Biology Thu, 17 Sep 2009 12:38:57 EST news172409914 (PhysOrg.com) -- Scientists from Queen Mary, University of London have discovered a new protein complex operating in fruit fly circadian clocks, which may also help to regulate our own biological clocks. http://www.physorg.com/news160215248.html Biology Wed, 29 Apr 2009 09:14:51 EST news160215248 Two previously identified pathways associated with aging in mice are connected, say researchers at the Stanford University School of Medicine. The finding reinforces what researchers have recently begun to suspect: that the age-related degeneration of tissues, organs and, yes, even facial skin with which we all struggle is an active, deliberate process rather than a gradual failure of tired cells. Derailing or slowing this molecular betrayal, although still far in the future, may enable us to one day tack years onto our lives -- or at least delay the appearance of that next wrinkle. http://www.physorg.com/news150642332.html Biology Thu, 08 Jan 2009 13:05:32 EST news150642332 It doesn't tick, it doesn't have hands, and it doesn't tell you what time of day it is. But a molecular clock does tell time -- on an epoch scale. The molecular clock, explained S. Blair Hedges, is a tool used to calculate the timing of evolutionary events. http://www.physorg.com/news146418967.html Biology Thu, 20 Nov 2008 15:56:07 EST news146418967
