Researchers have discovered that Atlantic killifish are now 8,000 times more resilient to high levels of toxic waste than other fish, allowing them to survive extreme levels of pollution that would normally be deadly. It sounds like an evolutionary success story, but examples like this are exceptionally rare in the animal kingdom.
Seventy years ago, American chemist Willard Libby devised an ingenious method for dating organic materials. His technique, known as carbon dating, revolutionized the field of archaeology.
Air pollution is killing the world’s children.
At least 2 billion kids globally are exposed daily to unhealthy levels of outdoor air pollution, according to a sobering UNICEF report released Monday. And about in 1 in 7 — or 300 million children — live in areas with the “most toxic levels of outdoor air pollution,” measured as six or more times higher than standards set by the World Health Organization.
