Another away game and another failure for Manchester United. True, they took part in a cracking match, scored two fine goals and showed character to come from behind twice to earn a point in a pulsating second period at West Brom, but that still doesn’t cut it. This is Manchester United we are talking about here…. a club striving to be the best around… not some mid-table outfit like Aston Villa or Hull City content to visit places like the Hawthorns and return home with a 2-2 draw. Work in progress they may be under Louis van Gaal, yet defensively at times last night, the Red Devils looked as if they were going backwards, not improving. More snakes than ladders.

Blue light can both set the mood and set in motion important biological responses. Researchers at the University of Pennsylvania’s School of Medicine and School of Arts and Sciences have teased apart the separate biological responses of the human eye to blue light, revealing an unexpected contest for control. Their work addresses the properties of melanopsin, a light-sensitive protein in the eye that establishes the rhythm of our day-night cycle and the familiar constriction of the pupil to bright light. They measured the pupil response to stimulation of melanopsin and of short-wave-sensitive (S) cones, the other blue light-sensing cells that operate in daylight. Surprisingly, they found that melanopsin and S-cones have opposite effects and compete for control of the pupil in blue light. Their complete results are published in the current issue of PNAS.
