All Stories by Nikk Ogasa

  1. Planetary Science

    NASA’s Perseverance rover found a new potential setting for Martian life

    Now atop Jezero Crater, the robotic explorer found quartz indicative of habitable environments and possibly the oldest rocks yet seen in the solar system.

  2. Earth

    Earth’s inner core may be changing shape

    Earthquake data suggest that all or small patches of the inner core's surface may be swelling and contracting.

  3. Climate

    Climate change made 2024 the hottest year on record. The heat was deadly

    Heat waves fueled by climate change killed scores of people and upended daily life. Here are some of those stories.

  4. Climate

    From electric cars to wildfires, how Trump may affect climate actions

    Trump’s first term, campaign pledges and nominees point to how efforts to address climate change and environmental issues may fare.

  5. Climate

    Climate change has amped up hurricane wind speeds by 29 kph on average

    Every single Atlantic hurricane in 2024 had wind speeds supercharged by warming seas. One even jumped two categories of intensity.

  6. Oceans

    The world’s largest coral was discovered in the South Pacific

    The behemoth coral, discovered in October in the Solomon Islands, is longer than a blue whale and older than the United States.

  7. Environment

    Fire-prone neighborhoods on the fringes of nature are rapidly expanding

    The transition zone where unoccupied wildlands meet developed areas increased globally by about 35 percent from 2000 to 2020.

  8. Tech

    Feather-inspired airplane flaps could boost flight performance

    Rows of flaps inspired by bird wing feathers improve airfoil performance by boosting lift, reducing drag and mitigating stall.

  9. Math

    Two teenagers have once again proved an ancient math rule

    Ne’Kiya Jackson and Calcea Johnson have published 10 trigonometric proofs of the Pythagorean theorem, a feat thought impossible for 2,000 years.

  10. Earth

    What leads rivers to suddenly change course?

    An analysis of satellite data could help predict where rivers will change their course and where their rerouted flows will go.

  11. Climate

    Why Hurricane Helene was so devastating

    The tempest caused record-breaking storm surge on the coast and widespread and deadly flooding and debris flows in the Appalachian Mountains.

  12. Oceans

    A vital ocean current is stable, for now

    The Florida Current, a major contributor to a system of ocean currents that regulate Earth’s climate, has not weakened as much as previously reported.
