MRI reveals genetic activity: Deciphering genes' roles in learning and memory
Doctors commonly use magnetic resonance imaging (MRI) to diagnose tumors, damage from stroke, and many other medical conditions. Neuroscientists also rely on it as a research tool for identifying parts of the brain that carry out different cognitive functions. Now, biological engineers are trying to adapt MRI to a much smaller scale, allowing researchers to visualize gene activity inside the brains of living animals.

Reflections on the Future of Medicine
Recently, I traveled through China. I climbed mountains, hiked through forests, crossed deep valleys. I visited cities of every size. I floated across lakes and traveled beautiful shorelines churning with life. As a man of a certain age, I began to compare the permanence of the timeless landscape with the evanescence of my own existence. Yet, as a scientist, I knew these reflections were flawed. Scientists are trained to think in terms of aeons, millenia, and lifetimes. Consider the paradox. Is it the solid mountain or fragile the forest that is permanent? Is it the massive shoreline cliffs or the teeming shore life that...

Mapping Traumatic Brain Injuries
There's been an increasing amount of media attention to the topic of Traumatic Brain Injury (TBI) -bolstered in part by conversations surrounding the 2015 Hollywood blockbuster Concussion. The movie Concussion describes a particular phenomenon, Chronic Traumatic Encephalopathy or CTE, which occurs in the brain after repeated high impact blows to the head. The diagnosis of CTE requires examining brain tissue under a microscope after death, so it can't be diagnosed in living individuals. But in fact, there are many types of TBI, with concussion being the mildest (but most common) form. Today, brain mapping techniques are mak...
