Unlocking Secrets of Memory and Time in the Brain
Our bodies know when to fall asleep and when to wake up. Our brains can keep track of short bursts of time like a mental stopwatch. But in our memories, our sense of time is fuzzy. Now, research is beginning to uncover how we put our memories in order. These new insights into the workings of the brain, paired with other findings, could help in the understanding and early detection of diseases such as dementia and Alzheimer’s, scientists say. The idea that we perceive time in our memory subjectively is well known in psychology, says Lila Davachi, a professor of psychology at Columbia University.

What Twins Can Tell Us About Who We Are
In December 1988, two sets of identical twins in Bogotá became test subjects in a study for which they had never volunteered. It was an experiment that could never be performed in a lab, and had never before been documented. And it became a testament to the eternal tug between nature and nurture in shaping who we are. This week, psychologist Nancy Segal tells the story of the Bogotá twins, which was a tragedy, a soap opera, and a science experiment, all rolled into one. And she explains why twin studies aren't just for twins. They can serve as a paradigm to understand age-old questions that affect us all: Is our fate written in our genes?
