Each Subcritical nuclear deployment is expected to cost approximately $1 billion in construction for a 300-megawatt facility, financed through a mix of equity and infrastructure debt.
Shane and Matt discussed that scientists still don't fully understand why yawning is contagious, with mirror neurons being the leading but unconfirmed theory.
In a dataset of ~1.2 million people, reaction time declined slowly from the 30s onward, but processing speed remained relatively stable until about age 60, then dropped sharply.
White matter makes up approximately 60% of the human brain — a higher proportion than any other species — and its degradation with age is one of the best predictors of cognitive decline.
Studies comparing Bolivian hunter-gatherers to industrialized populations found a bell-shaped curve between caloric availability and brain volume — both chronic caloric restriction and caloric excess shrink the brain.
Environmental exposures cannot be studied with RCTs in humans — you cannot randomize people to breathe polluted air for 20 years — leaving researchers reliant on flawed observational data.
Living near a highway simultaneously increases particulate matter, nitrogen dioxide, noise, and nighttime light — making it nearly impossible to isolate which specific exposure drives health harm.
Unlike a genetic marker like Lp(a) which can be measured once and assumed stable, environmental exposures vary by where you live, work, commute, exercise, and how your home is ventilated — making zip-code-level estimates very noisy.
Environmental exposures are invisible (except light), accumulate slowly, and can take years or decades for health effects to appear — making them uniquely difficult for the public to evaluate and creating strong polarization.
Completely untrained people shown just 5-second video clips can detect psychopathic personality traits with accuracy reasonably correlated to trained psychologists with full case files.
