    HAT-P 7b is a windy world. Stiff easterlies typically whip through the atmosphere of the distant exoplanet, but sometimes the powerful gales blow in surprisingly varied directions. Now, simulations of the planet’s magnetic field lines, illustrated here as a rainbow of scrawled marks, reveal that HAT-P 7b’s magnetic field influences the winds, even turning some into westerlies. The result, published May 15 in Nature Astronomy, could lead to a better understanding of the atmospheres of other exoplanets.

    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.

    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?
