Race, Gender and Alzheimer's
Big Think hosted a panel discussion highlighting cutting-edge Alzheimer's disease research as part of our Breakthroughs series, made possible by Pfizer.
This conversation features back-and-forth exchanges between top luminaries in the field, including Dr. Samuel Gandy, Mount Sinai Professor of Alzheimer's Disease Research; Dr. Leonard Guarente, Director of Glenn Lab for Science of Aging at MIT; Dr. Juan Troncoso, Director of the Brain Resource Center at Johns Hopkins University School of Medicine; and Dr. Ottavio Arancio, Professor of Pathology & Cell Biology at the Columbia University Medical Center. The panel was moderated by Meryl Comer, President of the Geoffrey Beene Foundation Alzheimer’s Initiative.
Are women and African-Americans at a higher risk for Alzheimer’s—as some data suggests—or are there other factors in play?
It's a development that could one day lead to much better treatments for osteoporosis, joint damage, and bone fractures.
- Scientists have isolated skeletal stem cells in adult and fetal bones for the first time.
- These cells could one day help treat damaged bone and cartilage.
- The team was able to grow skeletal stem cells from cells found within liposuctioned fat.
Gut bacteria play an important role in how you feel and think and how well your body fights off disease. New research shows that exercise can give your gut bacteria a boost.
- Two studies from the University of Illinois show that gut bacteria can be changed by exercise alone.
- Our understanding of how gut bacteria impacts our overall health is an emerging field, and this research sheds light on the many different ways exercise affects your body.
- Exercising to improve your gut bacteria will prevent diseases and encourage brain health.
A groundbreaking new study shows that octopuses seemed to exhibit uncharacteristically social behavior when given MDMA, the psychedelic drug commonly known as ecstasy.
- Octopuses, like humans, have genes that seem to code for serotonin transporters.
- Scientists gave MDMA to octopuses to see whether those genes translated into a binding site for serotonin, which regulates emotions and behavior in humans
- Octopuses, which are typically asocial creatures, seem to get friendlier while on MDMA, suggesting humans have more in common with the strange invertebrates than previously thought
