Our relationship with water still matters.
- According to new research, half of Neanderthal skulls studied had exostoses — aka "surfer's ear."
- The condition is common in mammals that spend a lot of time in water.
- Though today we are largely disconnected from nature, the consequences of our relationship to it are still felt.
Can nicotine keep Alzheimer's at bay? Dave Asprey explains how natural drugs can create super humans.
- Nootropics are colloquially known as 'smart drugs' – substances that increase cognitive function in healthy people. The word nootropic is a combination of two Greek words, noos meaning 'mind' and tropein meaning 'towards'.
- Dave Asprey discusses two naturally occurring smart drugs: Caffeine and nicotine. The latter might be a surprise, but while smoking, chewing tobacco and vaping have negative health consequences, there's evidence to suggest microdosing one milligram of nicotine, about 5% to 10% of a cigarette's worth, may protect against Alzheimer's.
- Beyond naturally occurring smart drugs, Asprey discusses aniracetam, a pharmaceutical cognitive enhancer pioneered in Russia that may improve memory input and recall.
Cognitive psychologist Donald Hoffman hypothesizes we evolved to experience a collective delusion — not objective reality.
- Donald Hoffman theorizes experiencing reality is disadvantageous to evolutionary fitness.
- His hypothesis calls for ditching the objectivity of matter and space-time and replacing them with a mathematical theory of consciousness.
- If correct, it could help us progress such intractable questions as the mind-body problem and the conflict between general relativity and quantum mechanics.
Atop hundreds of bus stops, rest stops for bees.
A mind-bending physics theory may explain why we have one reality instead of many.
