Can we get any smarter? (A conversation with my boy about neuroscience)

A PET image showing energy consumption in the hungry brain. Credit: Wiki “Can we get any smarter?” That is the question that piqued the interest of a 14-year-old boy yesterday when he saw it on the cover of the July issue of Scientific American.  What came next was a reading of Douglas Fox’s fascinating “The LimitsContinue reading “Can we get any smarter?

How Diet and Lifestyle Influence Telomere Length

Telomere length has a proportional and linear relationship to omega-3 fatty acids. With all the attention surrounding telomere length as a biomarker of biological aging, it’s worth pointing out that one nutrient may make a lot of difference: fish-derived omega-3 fatty acids. The higher the blood levels of fish-derived omega-3 acids in patients with coronaryContinue reading “How Diet and Lifestyle Influence Telomere Length”

Updated clinical vitamin D guidelines

Depression and telomeres

Reference: Wolkowitz et al. 2011 March. People who suffer from major depression have a higher risk of age-related illness and earlier mortality (1 &2). Researchers from University of California, San Francisco (UCSF), investigated (1) telomere length in depressed individuals versus matched controls and assessed other biological factors associated with telomere shortening. Led by Nobel laureateContinue reading “Depression and telomeres”
