Two of my SciBlings have recently covered papers that my readers should find interesting:

Joseph: Bright Light and Melatonin Treatment Improves Dementia:

Chris Chatham : Time Perception: In the Absence of "Time Sensation?":

In their newly in-press TICS article, Ivry and Schlerf review the state of the art in cognitive modeling of time perception - perhaps the most basic form of perception which has no sensory system dedicated to it.
