Intelligence and the DNA Revolution

EXCERPT: [...] Of the over 12 million SNPs analyzed, 336 correlated significantly with intelligence, implicating 22 different genes. [...] The big picture to emerge from research on the neurobiological underpinnings of intelligence and other psychological traits is that the nature vs. nurture debate is, once and for all, over. We are a product of both our genetic makeup and our environments, and the complex interplay between the two. Research aimed at better understanding this interplay will give scientists a richer understanding of both the similarities and differences in our psychological makeup....



Yawning — why is it so contagious and why should it matter?

EXCERPT: [...] Stephen Jackson, Professor of Cognitive Neuroscience, in the School of Psychology, led the multidisciplinary study. He said: “We suggest that these findings may be particularly important in understanding further the association between motor excitability and the occurrence of echophenomena in a wide range of clinical conditions that have been linked to increased cortical excitability and/or decreased physiological inhibition such as epilepsy, dementia, autism, and Tourette syndrome.”

EXCERPT: [...] At least one part of the Americas was already occupied by humans before that time, however, says new research on the skeleton of a male youth found in Chan Hol cave near Tulúm, Mexico. Dubbed the Young Man of Chan Hol, the remains date to 13,000 years ago, according to a paper published in the journal PLOS ONE. How he arrived at the location remains a great mystery given the timing and the fact that Mexico is well over 4,000 miles away from the Bering land crossing.

“Scenarios of travel by boat along the Pacific shoreline, the ‘Kelp Highway,’ must be taken seriously, but alternative migration routes by boat from Europe along the Greenland ice margin or via Antarctica are also possible, though highly speculative,” lead author Wolfgang Stinnesbeck of the Institute of Geosciences at Heidelberg University said. “If travel by boat is correct,” he added, “then likely camp sites are now set underwater due to the early Holocene rise of sea level....”
