“Zen” Bats It
Egyptian fruit bats apparently hit their food targets by deliberately not aiming at them. They point their sonar sound beam to either side of the target instead.
Egyptian fruit bats apparently hit their food targets by deliberately not aiming at them. They point their sonar sound beam to either side of the target instead. "The new findings by researchers from Maryland and the Weizmann Institute of Science in Israel suggest that this strategy optimizes the bats' ability to pinpoint the location of a target, but also makes it harder for them to detect a target in the first place. ‘We think that this tradeoff between detecting a object and determining its location is fundamental to any process that involves tracking an object whether done by a bat, a dog or a human, and whether accomplished through hearing, smell or sight,’ said coauthor Cynthia Moss, a University of Maryland professor of psychology, who directs interdisciplinary bat echolocation research in the university's Auditory Neuroethology Lab, better known as the bat lab. Moss, colleagues Nachum Ulanovsky and Yossi Yovel of the Weizmann Institute, and Ben Falk, a graduate student of Moss's in Maryland's Neuroscience and Cognitive Science Program, published their findings in the journal Science. Ulanovsky, the paper's corresponding author, was a Maryland postdoctoral student under Moss."
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.
