James Watson and Edward O. Wilson: An Intellectual Entente

James D. Watson and Edward O. Wilson, two major exponents of modern biology, reflect on the convergence of the evolutionary and molecular approaches in their field.

Brain images show the differences in activity patterns between the two groups of subjects that professor of psychology Jill Hooley examined. The brains of recovered depressed subjects (left) had more active amygdalae while listening to criticism than did the brains of subjects who had never been depressed. The brains of the latter showed more activation in the dorsolateral prefrontal cortex (center) and the anterior cingulate cortex (right) compared to brains of subjects with a history of depression.

How Depression Lingers

After depression patients recover, their brains still process criticism differently.

All in a day’s treatment: Khaled, seen in these photographs with hemapheresis practitioner Beverly Gedutis, R.N., and author David Nathan, spent May 8 at Children’s Hospital Boston, where for decades he has been transfused with red blood cells every three weeks. The bottles he carries below contain the iron chelator deferisirox.

Lessons from an Unexpected Life

One patient’s struggle with chronic illness highlights the complexities of modern medicine and the healthcare challenge.

Robert Patterson’s letter to Thomas Jefferson included a worked example of his cipher. He began by writing his message in lower-case letters and in columns, running top to bottom like Chinese. This example begins with the words “Buonaparte has at last given peace to Europe,” legible in the first two columns.
