Exploring Mitochondrial Bioenergetics, Optogenetics, Human Health And Aging — Dr. Brandon Berry, Ph.D., University of Washington.

Dr. Brandon Berry, Ph.D. (https://halo.dlmp.uw.edu/people/brandon-berry/) is a postdoctoral researcher in the Kaeberlein Laboratory at University of Washington where his research focuses on how aging and metabolism are linked.

Dr. Berry is interested in how mitochondria, the powerhouses of cells, contribute to and modulate functional decline that occurs during aging, and he is involved in using novel tools, like optogenetics, to precisely control mitochondria and metabolism with light. Through these types of experiments, he can more precisely determine if mitochondrial dysfunction is a cause or a consequence of metabolic aging and may reveal new ways to understand and impact health.

Scientists have discovered not only that animals age more quickly when they don’t have enough of the amino acid taurine in the body, but that oral taurine supplements can delay aging and increase a healthy lifespan.

An international team of researchers found that taurine supplements delayed aging in worms, mice, and monkeys, and increased the healthy lifespan of middle-aged mice by up to 12 percent.

“For the last 25 years, scientists have been trying to find factors that not only let us live longer, but also increase health span, the time we remain healthy in our old age,” says biologist Vijay Yadav from Columbia University, senior author on the study.

Switching to a diet full of fresh veggies and low in processed foods could do wonders for your brain’s biological age, new research shows.

According to the international team of researchers who ran the study, eating a Mediterranean diet rich in vegetables, seafood, and whole grains appears to slow the signs of accelerated brain aging typically seen in obesity with as little as 1 percent loss in body weight.

Brain scans taken after 18 months showed the participants’ brain age appearing almost 9 months younger than expected, compared to estimates of their brain’s chronological age.

This is a new channel with Liz Parrish. This is an hour with Aubrey.

Most people consider #aging to be a normal part of the cycle of #life and #death. But, did you know that some people see aging merely as a disease?
Which means that they believe there is a cure for aging.
And, these people are in pursuit of that cure.

So, who are these people?

Enter Kim’s class, 2.74 (Bio-Inspired Robotics).

According to Kim, researchers need to understand this cognitive bias, this tendency toward anthropomorphism, in order to even begin developing robots that can help humans with their physical movements. While Kim’s research interest is in building robots that could help people, such as the elderly in an aging population with fewer young people to perform services, such advancement is not even possible without understanding biology, biomechanics, and how much we don’t understand about our own everyday movements.

“One big thing students should learn in this class is not necessarily to understand how we move our body but the fact that we don’t understand how we move,” Kim says. “One of our ultimate goals in robotics is to develop robots that help elderly people by mimicking how we use our arms and legs, but if you don’t realize how little we know about how we move, we cannot even start tackling this problem.”

Chemical signals from contracting muscles can influence the growth of brain networks, according to new research published in Neuroscience. The study highlights the importance of physical activity to mental health, and the findings could also help contribute to the development of more effective treatments for cognitive disorders such as Alzheimer’s disease.

Previous studies had shown that exercise has significant benefits for cognitive health, even when initiated at late stages in life. Exercise has been associated with long-term changes in the hippocampus, a brain region crucial for learning and memory, including increased neurogenesis, synaptogenesis, and enlarged volume.

However, the specific mechanisms through which exercise produces these changes in the hippocampus were not well understood. By uncovering these mechanisms, the authors behind the new study aim to develop exercise-based treatments for cognitive pathologies that affect the hippocampus, such as Alzheimer’s disease, stress, depression, anxiety, and normal aging.
