Life On Mars?
Analysis of images of “ancient lakes” on Mars’ equator suggests similarities to lakes found in Alaska and Siberia, adding to the likelihood that there was once life on the Red Planet.
"An analysis of satellite images revealed craters left along Mars' equator by lakes similar to those found in Alaska and Siberia. Importantly, the lakes were linked by small tributaries and rivers, suggesting water was moving which means they would have been able to support microbial life, scientists including a team from Imperial College London found. The lakes, up to 12 miles long, have been dated back three billion years and were probably created following volcanic activity in the region around the equator, which was previously thought to be dry and arid. Previously scientists believed that the lakes on Mars during that period were merely ice so the findings widen the period of time in which now extinct life forms could have existed on Mars, researchers believe. The results come just months after Nasa, the American space agency, announced that they had found water on the surface of the planet, raising more hopes that signs of life could some day be discovered."
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.
