    How much do you know about that three-pound hunk of tissue in your head - your brain? Its structure and function drive your behavior in profound ways. Scientists are studying the brain and its chemicals to find behavioral patterns, to figure out the sources of good moods and random outbursts, for example. This compilation from Science News for Students turns to brain science to answer all sorts of questions: Can you actually be addicted to your phone? Why is it so hard to sleep away from home?

    Planting trees is often touted as a strategy to make cities greener, cleaner and healthier. But during heat waves, city trees actually boost air pollution levels. When temperatures rise, as much as 60 percent of ground-level ozone is created with the help of chemicals emitted by urban shrubbery, researchers report May 17 in Environmental Science & Technology.

    On November 12, a robot called Philae fell from its mother ship Rosetta onto comet 67P/Churyumov–Gerasimenko, touching down not once but three times. Philae’s final resting place, however, put it in a tough spot — in a crevice, in the shadow of a cliff, with two legs on the ground and one in space.

    Out among the stars, toward the constellation Capricornus, a red sphere floats freely through space. It doesn’t have enough mass to fuse atoms for fuel, as stars do, and it’s too small to be a failed star. In nearly every way, this drifter, known as PSO J318.5-22, is like a planet. Except it fails one key test for planethood: It does not orbit a star.
