Humans seem to be the only animals who produce one of three different types of tears. Can you guess what it is? Let's look at the science behind crying.
We have scientific evidence that masks effectively and dramatically reduce the spread of COVID-19, yet myths about mask-wearing abound. Let's put them to rest and mask up!
Congress recently introduced a bill to prohibit the President from using weapons to alter weather patterns. But can you tame a hurricane by nuking it off the map?
