Children Born To Older Parents Tend To Have Fewer Behavior Problems

children
Children of older parents tend to have fewer externalizing behavior problems than children of younger parents, new research indicates. The researchers also found that parents' age was unrelated to children's internalizing behaviors. Researchers at Utrecht University, Vrije Universiteit Amsterdam, Erasmus Medical Center, and University Medical Center Groningen looked at externalizing behaviors (e.g., aggression) and internalizing …

Why Strength Training Might Come At The Expense Of Endurance Muscles

junction in fast-twitch muscle
The neurotransmitter brain-derived neurotrophic factor (BDNF) is produced by the muscle and acts on both muscles and synapses, researchers at the University of Basel's Biozentrum have found. In their recent work, Prof. Christoph Handschin's research group at the Biozentrum closely studied strength muscles and the myokine BDNF, which plays an important role in the formation …

Alzheimer’s Gene APOE May Effect Cognition Before Adulthood

ACMSD
A gene associated with Alzheimer’s disease may have an impact on cognitive health much sooner than previously realized, new research suggests. The APOE gene creates a protein, apolipoprotein E, which packages cholesterol and other fats to transport them through the bloodstream. There are three versions, or alleles, of APOE. One of those is the APOE4 …

Tau Proteins Spread More Easily In The Aging Brain

P301Ltau misfolding
Certain molecules involved in Alzheimer's disease called tau-proteins spread more easily in the aging brain, new research in mice from German investigators suggests. The study was carried out in collaboration with researchers in the US at Harvard Medical School and Massachusetts General Hospital. Alzheimer’s disease usually begins with memory decline and later affects other cognitive …

Hippocampal Neurogenesis Persists Through The Tenth Decade Of Life

Neurons
New neurons continue to form well into old age, University of Illinois at Chicago researchers examining post-mortem brain tissue from people ages 79 to 99 have found. The study provides evidence that this occurs even in people with cognitive impairment and Alzheimer's disease, although neurogenesis is significantly reduced in these people compared to older adults …

SIRT6 Gene Behind More Efficient DNA Repair In Longer Living Species

genetic mutation
The gene sirtuin 6 (SIRT6) is responsible for more efficient DNA repair in species with longer lifespans, new research from the University of Rochester indicates. The finding sheds light on new targets for anti-aging interventions and could help prevent age-related diseases. As humans and other mammals grow older, their DNA is increasingly prone to breaks, …
