The Moments We Don’t Forget
Dr. Gary Small is a professor of psychiatry at the UCLA Semel Institute where he directs the Memory and Aging Research Center and the UCLA Center on Aging. Dr. Small invented the first brain scan that allows doctors to see the physical evidence of brain aging and Alzheimer’s disease in living people. He now leads a team of neuroscientists who are demonstrating that exposure to computer technology causes rapid and profound changes in brain neural circuitry. A leading experts on brain science, he has been named by Scientific American magazine as one of the world’s top innovators in science and technology.
Question: Why does memory appear random?
Gary Small: It seems that memory is random. Some things we recall better than others. It’s probably not random. It’s just that we don’t always understand what makes one experience more memorable than another. One way to wrap your head around this is to think emotional memory. Anytime we experience something in a heightened emotional state we’re more likely to remember it. For example, most of us who are baby boomer remember exactly what was happening to them the day that President Kennedy was shot, but it’s unlikely that we remember what was going on the week before or the week after, so there are experiences that taint or exaggerate certain memories that make them fix into our memory stores better than others.
Question: Why do memories change over time?
Gary Small: Often our memories seem to be malleable, that is they seem to change over time and I’ve had the experience. I’m sure many of us have had the experience where we go back to a place and we’re convinced that It’s on the other side of the street or they’re something different about it and yet that hadn’t occurred and what happens is that memory is basically stored in little neurochemical packets in the brain and there are a lot of physiological processes that can affect those neurochemical packets, so they can be changed and our memories can deceive us very often.
Why is it that we remember exactly where we were on 9/11 or the day Kennedy was assassinated, but very little of what happened on the days surrounding such events?
Educators and administrators must build new supports for faculty and student success in a world where the classroom might become virtual in the blink of an eye.
- If you or someone you know is attending school remotely, you are more than likely learning through emergency remote instruction, which is not the same as online learning, write Rich DeMillo and Steve Harmon.
- Education institutions must properly define and understand the difference between a course that is designed from inception to be taught in an online format and a course that has been rapidly converted to be offered to remote students.
- In a future involving more online instruction than any of us ever imagined, it will be crucial to meticulously design factors like learner navigation, interactive recordings, feedback loops, exams and office hours in order to maximize learning potential within the virtual environment.
Placing science and religion at opposite ends of the belief spectrum is to ignore their unique purposes.
- Science and religion (fact versus faith) are often seen as two incongruous groups. When you consider the purpose of each and the questions that they seek to answer, the comparison becomes less black and white.
- This video features religious scholars, a primatologist, a neuroendocrinologist, a comedian, and other brilliant minds considering, among other things, the evolutionary function that religion serves, the power of symbols, and the human need to learn, explore, and know the world around us so that it becomes a less scary place.
- "I think most people are actually kind of comfortable with the idea that science is a reliable way to learn about nature, but it's not the whole story and there's a place also for religion, for faith, for theology, for philosophy," says Francis Collins, American geneticist and director of the National Institutes of Health (NIH). "But that harmony perspective doesn't get as much attention. Nobody is as interested in harmony as they are in conflict."

A leading British space scientist thinks there is life under the ice sheets of Europa.
- A British scientist named Professor Monica Grady recently came out in support of extraterrestrial life on Europa.
- Europa, the sixth largest moon in the solar system, may have favorable conditions for life under its miles of ice.
- The moon is one of Jupiter's 79.

A study finds people are more influenced by what the other party says than their own. What gives?
- A new study has found evidence suggesting that conservative climate skepticism is driven by reactions to liberal support for science.
- This was determined both by comparing polling data to records of cues given by leaders, and through a survey.
- The findings could lead to new methods of influencing public opinion.
