Belgian scientists have revealed a refined explanation for the chemical process that’s currently degrading Vincent van Gogh’s famous paintings, which are losing their bright red.

Using sophisticated X-ray crystallographic methods, the researchers identified a key carbon mineral called plumbonacrite in one of his paintings, which explains the process even better.
A study suggests that immense amounts of lead are being ingested in Africa, since extensive use of cookware made from recycled materials leaks lead into the food. This is the first time the extent of lead poisoning has been assessed. Results suggest that in some instances, as much as 200 times the threshold amount for lead poisoning is being ingested.
Four hundred of the most popular lipsticks in the US contain trace levels of lead, according to tests conducted by the federal government – a number much bigger than what was expected. Five of the L’Oreal and Maybelline lipsticks ranked among the top 10 most contaminated brands, as well as two Cover Girl and two NARS. The researchers from the
