MASSACHUSETTS INSTITUTE OF TECHNOLOGY CAMBRIDGE, MA — As cells perform their everyday functions, they turn on a variety of genes and cellular pathways. MIT engineers have now coaxed cells to inscribe the history of these events in a long protein chain that can be imaged using a light microscope. Cells programmed to produce these chains...
UNIVERSITY OF CALIFORNIA – LOS ANGELES HEALTH SCIENCES Our brains rarely record single memories—instead, they store memories into groups so that the recollection of one significant memory triggers the recall of others connected by time. As we age, however, our brains gradually lose this ability to link related memories. Now UCLA researchers have discovered...

Does walking into Staples remind you of back-to-school shopping, even years after graduating? Or, have you ever been introduced...
FEBRUARY 7, 2022 by Steve Fink Memories stick with us for a reason. We hang onto important events and life experiences from our past, however, many of these seemingly crucial memories have also been forgotten. The act of forgetting often has a negative connotation. Many perceive forgetting as a form of memory loss. However, scientists...
One of the greatest mysteries in neuroscience is how groups of brain cells work together to form and maintain memories. Now a team of Columbia neuroscientists led by Attila Losonczy of the Zuckerman Institute has achieved a breakthrough in this area, capturing how brain cells in mice perform computations as the animals navigate the world. The researchers accomplished...
Fish that glow; a tailor-made microscope; a new way to catalog science. After six years, researchers produce the first snapshots of memory in a living animal. What physical changes occur in the brain when a memory is made? A team of researchers at the University of Southern California has, for the first time, answered this...
