Axonal growth cones can turn in response to minute concentration differences in extracellular guidance cues. Surprising new work suggests that these cues might steer the growth cone by inducing rapid local changes in protein levels.

In a community based study, height and weight increments of 441 Nepali children aged 0-6 years were measured before harvest and six months later and compared with centile standards derived from American children. Low mean growth velocities for height were found only in children under 2 years of age, and for weight during the first 18 months. The mean height for age standard deviation score for ...

It discusses the strengths and weaknesses that exp...
