Light and Time

Two of my SciBlings have recently covered papers that my readers should find interesting:
Joseph: Bright Light and Melatonin Treatment Improves Dementia:

A study published in JAMA indicates that treatment with bright light alone (1,000 lux), or bright light combined with melatonin, can improve symptoms in patients with dementia. Melatonin alone appeared to have a slight adverse effect.

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.
