Half of US Adults Exposed To Harmful Lead Levels As Kids – Slashdot

The scientists from Florida State University and Duke University also found that 90% of children born in the U.S. between 1950 and 1981 had blood-lead levels higher than the CDC threshold. And the researchers found significant impact on cognitive development: on average, early childhood exposure to lead resulted in a 2.6-point drop in IQ. The researchers only examined lead exposure caused by leaded gasoline, the dominant form of exposure from the 1940s to the late 1980s, according to data from the U.S. Geological Survey. Leaded gasoline for on-road vehicles was phased out starting in the 1970s, then finally banned in 1996. Source: Half of US Adults Exposed To Harmful Lead Levels As Kids – Slashdot

We’re all human: Scientists create world’s biggest family tree linking 27 million people – Study Finds

“We have basically built a huge family tree, a genealogy for all of humanity that models as exactly as we can the history that generated all the genetic variation we find in humans today. This genealogy allows us to see how every person’s genetic sequence relates to every other, along all the points of the genome,” says principal author Dr. Yan Wong in a university release.

The University of Oxford team combed through eight databases containing 3,609 different genome sequences from 215 populations. They included samples from across the world; some being over 100,000 years-old. The resulting network contained almost 27 million ancestors and 231 million ancestral lineages.
