Young babies make many squeals, vowel-like sounds, growls, and short word-like sounds such as 'ba' or 'aga.' Those precursors to speech or 'protophones' are later replaced with early words and, eventually, whole phrases and sentences.

Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, is a fatal motor neuron disease that causes people to gradually lose control of their muscles. There is no cure, and current treatments focus on reducing symptoms and providing supportive care.

The results of a new clinical trial suggest that the first drug therapy to slow the progression of nearsightedness in kids could be on the horizon. The three-year study found that a daily drop in each eye of a low dose of atropine, a drug used to dilate pupils, was better than a placebo at limiting eyeglass prescription changes and inhibiting elongation of the eye in nearsighted children aged 6 to 10.
