Millions of surgical procedures performed each year would not be possible without the aid of general anesthesia, the miraculous medical ability to turn off consciousness in a reversible and controllable way.
Researchers are using this powerful tool to better understand how the brain reconstitutes consciousness and cognition after disruptions caused by sleep, medical procedures requiring anesthesia, and neurological dysfunctions such as coma.
In a new study published in the journal
eLife, a team led by anesthesiologists George Mashour, M.D., Ph.D. of University of Michigan Medical School, Michigan Medicine, Max Kelz, M.D., Ph.D. of the University of Pennsylvania Medical School, and Michael Avidan, MBBCh of the Washington University School of Medicine used the anesthetics propofol and isoflurane in humans to study the patterns of reemerging consciousness and cognitive function after anesthesia.

Throughout the history of Davis & Elkins College, there have been a handful of individuals whose transformational leadership and commitment have fundamentally altered the trajectory of this institution. St. Louis resident Mr. James S. McDonnell III deserves an honored place on this elite list.
Mr. McDonnell’s journey with Davis & Elkins College began when his daughter, Marcella McDonnell Stevens, enrolled at D&E in 1981. Four years later, at her graduation, Jim provided the commencement address. At that ceremony, he was awarded an Honorary Doctor of Laws. Jim and Elizabeth “Libby” McDonnell began their generous financial support of the College at that time. An endowed faculty chair in business and economics was a result of Mr. McDonnell’s generosity, and was given in honor of Dr. Gloria M. Payne who was highly influential to Marcella McDonnell during her years as a student.

Rachel Owen earned her Ph.D. in soil science, studying
the impact of a changing climate on wetland ecosystems and landowner perceptions of climate threats. But some of her other skills, as a diplomat and a “science translator,” are just as crucial in helping Missouri lawmakers navigate complicated scientific issues.
Owen is the executive director of MOST, The Missouri Science and Technology Policy Initiative. In 2016, she started the group with two other graduate students to explore what science advising at the state level might look like.
The aim was to make non-partisan experts available to state legislators; to answer questions about the complex science topics crossing their desks.

Your Feelings About Memories Shape Your Decisions
People base their decisions on subjective memory how they feel about a memory more than on its accuracy, researchers report.
When we recall a memory, we retrieve specific details about it: where, when, with whom. But we often also experience a vivid feeling of remembering the event, sometimes almost reliving it. Memory researchers call these processes objective and subjective memory, respectively.
