“00:13:35 - Humans are programmed to deal with stress and could benefit from turning on the "genetic switches" that respond to stress, a process called hormesis. 00:18:20 - The emotional highs and lows Rhonda experiences when entering the "monster soup" during surfing.”

“A variety of elements influence how physically active we are, including genetic, cultural, and environmental factors. Evidence from a new study suggests that epigenetic changes in agouti-related proteins may regulate voluntary exercise behavior in mice.”

“They also analyzed genetic markers related to brain function in both groups. Mice with active grandfathers had better memory recall, particularly in tasks requiring spatial (recalling locations) and non-spatial (recalling facts and events) memory.”

“Researchers collected information from more than 600 older adults regarding their age, sex, education, use of beta-blockers (drugs that lower heart rate), and APOE4 gene status (a genetic risk factor for Alzheimer's).”

“Genetic variation in HDAC4 among the women was linked to a lower level of HDAC4 gene activity and differences in their ability to respond to and recover from fear, and also differences in "resting state" brain imaging.”

“The disease is caused by a single genetic mutation, called a CAG repeat, that drives abnormal protein folding and aggregation of the huntingtin protein and subsequent death of striatal neurons.”

“But a new study in mice that carry the APOE4 gene variant, the primary genetic risk factor for Alzheimer's disease, shows that DHA – a type of omega-3 fatty acid found in fish – protects against these losses.”

“They also used Mendelian randomization—a method that leverages genetic data to identify causal relationships—to explore further whether omega-3s directly influence the risk of developing autoimmune diseases.”

“A recent study found that a nasal spray that delivered neural stem cell extracellular vesicles—tiny particles that carry proteins and genetic material—reduced inflammation and improved brain function in a mouse model of Alzheimer’s disease, offering a safer, less risky approach.”

“They are released by cells and influence the behavior of other cells. Designer cytokines are genetically engineered proteins that perform specific functions. The authors of the study engineered hyper-interleukin-6, a cytokine that has been shown to regrow neurons of the visual system.”
