Proof of Genetic Link to Human Intelligence
Scientists have provided the first direct biological evidence for a genetic contribution to intelligence in humans. It will also enhance learning on how to maintain intellectual abilities.
What's the Latest Development?
After a study of two types of intelligence in more than 3,500 people, scientists say they have the first direct biological evidence for a genetic contribution to intelligence in humans. They examined more than half a million genetic markers on every person in the study, concluding that 40-50% of the subjects' differences in intellectual abilities could be traced to genetic differences.
What's the Big Idea?
One of the scientists, Dr. Neil Pendleton, said that the findings would help researchers better understand how the genes interacted with each other and the environment, which had an equally significant contribution. "We will take this work forward to find the biological mechanisms that could maintain our intellectual abilities and wellbeing in late life.”
These five main food groups are important for your brain's health and likely to boost the production of feel-good chemicals.
We all know eating “healthy” food is good for our physical health and can decrease our risk of developing diabetes, cancer, obesity and heart disease. What is not as well known is that eating healthy food is also good for our mental health and can decrease our risk of depression and anxiety.
Infographics show the classes and anxieties in the supposedly classless U.S. economy.
For those of us who follow politics, we’re used to commentators referring to the President’s low approval rating as a surprise given the U.S.'s “booming” economy. This seeming disconnect, however, should really prompt us to reconsider the measurements by which we assess the health of an economy. With a robust U.S. stock market and GDP and low unemployment figures, it’s easy to see why some think all is well. But looking at real U.S. wages, which have remained stagnant—and have, thus, in effect gone down given rising costs from inflation—a very different picture emerges. For the 1%, the economy is booming. For the rest of us, it’s hard to even know where we stand. A recent study by Porch (a home-improvement company) of blue-collar vs. white-collar workers shows how traditional categories are becoming less distinct—the study references "new-collar" workers, who require technical certifications but not college degrees. And a set of recent infographics from CreditLoan capturing the thoughts of America’s middle class as defined by the Pew Research Center shows how confused we are.
