Curiosity has found water on Mars. Not lakes or oceans though. When the NASA rover analyzed soil from the surface, it found about two percent is made up of ice. Researchers say that could have implications for future Mars explorers, who could theoretically take the soil -- heat it up -- and get water.
Differences in your brain structure could determine whether you're a early bird or a night owl. A new study says around 10 percent of people are early birds and 20 percent are night owls. And there are health concerns for night owls. Their white matter, which speeds up the transmission of nerve signals, is degraded in areas of the brain often associated with depression, though the exact affect of that on the person is not yet clear.
And if you've ever had the sneaking suspicion that people are whispering behind your back -- how about monkeys? A family of cotton-top tamarins at Central Park Zoo are the first non-human primates caught in the act of whispering. Researchers were trying to study mobbing behavior, where the monkeys gang up and yell at an intruder, but when they sent in the supervisor the monkeys didn't like, they noticed the tamarins were communicating quietly instead -- akin to human whispering.
