How did the weighting of Nobel Prize nominations affect the overall ranking, and what are the implications of this approach?

European countries dominated the ranking, with Switzerland, the U.K., and the Netherlands leading. The U.S.'s high Nobel Prize nominations significantly boosted its score, highlighting the historical weighting of this metric. Germany's lower education attainment surprised given its academic standing.

Roman Lead Pollution Lowered Average IQ by 2–3 Points

Analysis of Greenland ice cores reveals that Roman silver smelting released over 500,000 tons of lead into the atmosphere from 500 BC to 600 AD, lowering the average Roman IQ by 2–3 points due to widespread lead exposure.

What specific sources contributed to lead pollution during the Roman era, and how did lead levels fluctuate over time?

Analysis of Greenland ice cores revealed a correlation between Roman lead emissions and atmospheric lead levels from 500 BC to 600 AD. Lead concentrations increased significantly during the Roman Republic and Empire, declining only after the Antonine Plague. This contamination is linked to widespread mining activities in Spain, the Balkans, France, and Britain.

Fluoride Exposure Linked to Lower IQ in Children: Nine-Year Study

A nine-year study found a correlation between higher fluoride levels and lower IQ scores in children; each one-part-per-million increase in urine fluoride correlated with roughly a one-point IQ decrease, prompting a federal judge to order increased EPA regulation of fluoride.

How did the researchers control for potential biases in the included studies, and what are the limitations of the study's methodology?

The study, conducted under the U.S. government's National Toxicology Program, analyzed 74 studies from 10 countries, predominantly China. Researchers accounted for various factors, including age, IQ testing methods, and fluoride measurement precision (urine vs. water). Consistent findings across analyses showed a correlation between higher fluoride exposure and lower IQ scores.

What was the impact of lead pollution from Roman mines on the cognitive abilities of children in the Roman Empire?

A new study reveals that lead pollution from Roman mines significantly lowered the IQ of children in the Roman Empire by 2-3 points. This pollution, primarily impacting children aged 1-5, resulted from lead emissions during the Pax Romana (50 BC - 180 AD), reaching concentrations up to 13 nanograms per cubic meter of air in Andalusia. The study used ice core analysis and a computer model to estimate lead dispersal.
