Cardiologists Warn About Microplastics and Lead—Try These Replacements
Rising Concerns Around Microplastics and Lead Microplastics and lead exposure are two public health concerns that have captured the attention of cardiologists in recent years. While the science is still evolving, mounting evidence suggests that tiny plastic particles and heavy metals can influence cardiovascular risk factors such as inflammation, oxidative stress, and blood pressure. As…

Ancient Lead Exposure Shaped Human Brain Evolution Over Millennia
Lead in the ancient world: a hidden driver of evolution For decades, scientists viewed lead exposure as a modern problem tied to mining, manufacturing, and everyday products. A groundbreaking study published in Science Advances turns that idea on its head, suggesting that our hominin ancestors were intermittently exposed to lead for nearly two million years.…

Ancient Lead Exposure Shaped the Evolution of the Human Brain and Language
Ancient Lead Exposure: A Hidden Thread in Human Evolution New findings published in Science Advances reveal that our ancestors faced intermittent lead exposure for nearly two million years, long before industrial activity. The study stitches together fossil geochemistry, brain organoid experiments, and evolutionary genetics to propose that the toxic metal may have subtly steered the…

Lead Exposure Edge: Ancient Humans Gained Advantage
Ancient Lead Exposure: A Surprising Footnote in Human Evolution Lead, long seen as a modern toxin, might have shadowed our ancestors for nearly 2 million years. A new international study suggests that episodic lead exposure could have provided ancient humans with an edge over Neanderthals and other early relatives. By examining fossilized teeth and conducting…
