This Week's Letters

A new view of how plants are related is questioned. A model for how infants extract and use algebraic rules is proposed. A report on grant funding at the National Institutes of Health is offered, with the conclusion that "sufficient funds be provided to minimize all too costly interruptions in funding...." And a crucial control in molecular regulation studies is said to be increasingly overlooked.
