Intense star formation within resolved compact regions in a galaxy at z = 2.3.

Massive galaxies in the early Universe have been shown to be forming stars at surprisingly high rates. Prominent examples are dust-obscured galaxies which are luminous when observed at sub-millimetre wavelengths and which may be forming stars at a rate of 1,000 solar masses (M(middle dot in circle)) per year. These intense bursts of star formation are believed to be driven by mergers between gas-rich galaxies.

The effect of colored lenses on the visual evoked response in children with visual stress.

Purpose: Some children with visual stress and/or headaches have fewer symptoms when wearing colored lenses. Although subjective reports of improved perception exist, few objective correlates of these effects have been established.

Methods: In a pilot study, 10 children who wore Intuitive Colorimeter lenses, and claimed benefit, and two asymptomatic children were tested.

Childhood visual experience affects adult voluntary ocular motor control.

Purpose: To quantify the effects of childhood visual experience/chronic visual deprivation upon adult voluntary ocular motor control.

Methods: Eye movements of blind and sighted adults were elicited and videotaped in total darkness. The videotaped responses were digitized using an eye tracker, yielding data from 10 congenitally blind (infantile onset, blindness before age 1 year), 16 adventitiously blind, and 9 sighted persons.
