  1. Climate

    Zapping clouds with lasers could alter Earth’s climate

    Scientists zapped ice crystals in a lab. They were exploring whether this approach might be used to break those crystals in clouds — potentially as a way to cool Earth’s fever.

  2. Space

    Biologist Kate Rubins is headed to space

    Molecular biologist and astronaut Kate Rubins has spent 7 years preparing for a mission to the International Space Station. She blasts off this month.

  3. Computing

    ‘Couch potatoes’ tend to be TV-energy hogs

    Many government programs urge people to save electricity by using more efficient TVs. Here’s why these programs should target “couch potatoes.”

  4. Planets

    The ultimate getaway — visiting the Red Planet

    At a recent summit, experts discussed the challenges of a human mission to Mars — and how to land a crew there within 20 years.

  5. Tech

    Helping MS patients get a grip on things

    An Irish teen has invented a device that helps people with multiple sclerosis address the “clenched fist” symptom that afflicts most such patients.

  6. Tech

    Teen offers technology that could help brain surgeons

    It can reproduce plastic models of the precise faulty vessels that need fixing. Now doctors can see them, hold them and practice on them long before they pick up a scalpel.

  7. Health & Medicine

    Common plant could help fight Zika virus

    A teen discovered that extracts from leaves of the San Francisco plant (Codiaeum variegatum) kill larvae of the mosquito that helps spread the Zika and dengue fever viruses.

  8. Teen gymnast finds how best to keep her grip

    Unsatisfied with anecdotal opinions on which type of gymnastics chalk was best, a teen used science to find out for herself.

  9. Health & Medicine

    Bed bugs have favorite colors

    Bed bugs change their color preferences as they get older. Adults like red and black, which may help the dark bugs avoid predators.

  10. Tech

    Where did that turbine blade get smacked?

    A new technique can help engineers figure out where a bird or other object collided with a wind turbine or other whirling blade.

  11. Brain

    Small region of brain recognizes facial expressions

    Scientists identify the brain region responsible for recognizing facial expressions in others. It helps us know whether others are happy or sad.

  12. Tech

    Control a computer with your tongue

    Thousands of severely paralyzed people could venture into cyberspace with the use of this new tongue-controlled computer mouse. It was developed by a teen.
