    President Obama is passionate, and vocal, about combating climate change. As his tenure draws to a close, science correspondent Miles O’Brien reviews the administration’s environmental policy — from the 2009 “cap-and-trade” climate bill, to the 2015 Paris accord, to executive orders on greenhouse gas emissions — in assessing the president’s legacy.

    Over a thousand years ago, Polynesians followed the stars in the Mauna Kea sky on their path to Hawaii. Those stars are now of interest to astronomers, who believe the mountain’s summit is the perfect spot to build a giant, cutting-edge telescope. But native Hawaiians view that peak as a sacred space. Science correspondent Miles O’Brien reports for the second in our series about the controversy. Continue reading

    Former astronaut and senator John Glenn has died at age 95. In every chapter of his life, whether on Earth or above it, Glenn accumulated achievements — serving as a Marine fighter pilot in two wars and later launching into space exploration. After retiring from politics, he continued to advocate for NASA. Hari Sreenivasan speaks with science correspondent Miles O’Brien about this American icon. Continue reading

    A trio of scientists won the Nobel Prize in Chemistry for creating some of the world’s tiniest machines. Their nanorobots use extremely controlled movements to perform tasks that the creators hope will one day be useful in the world of medicine. Science correspondent Miles O’Brien joins Hari Sreenivasan to discuss these mini machines and the other science and medicine Nobels awarded this week. Continue reading

    Scientists have discovered a potentially habitable new world, a mere four light years away from Earth. They call the planet “Proxima B,” and it may feature characteristics that are just right for human life. Nonetheless, it has some major differences from Earth — a year on the planet lasts only 11 days. Hari Sreenivasan speaks with WGBH’s science correspondent Miles O’Brien for background.

    Hawaii’s Kilauea has been erupting for over 30 years, making it the longest-flowing volcano on earth. Because of this remarkable activity, it is also currently the most researched. Geologist Mike Garcia has studied Kilauea for decades and believes that analyzing the chemical composition of pieces of the volcano may yield clues to its future behavior. Science correspondent Miles O’Brien reports. Continue reading

    Lenny and Amy’s 5-year-old son has epilepsy. When conventional medications caused terrible side effects, they started giving him a daily drop of cannabis oil, with dramatic results. But it’s a calculated risk: While there is anecdotal evidence of cannabis’ effectiveness, scientists face research roadblocks because it’s a schedule 1 controlled substance. Science correspondent Miles O’Brien reports. Continue reading

    Confined spaces, low gravity and high concentrations of oxygen mean any unexpected fire on a space station could well be a death sentence, especially since fire extinguishers aren’t very effective away from Earth. So NASA scientists are trying to develop a new kind of firefighting tool by starting their own space fires and studying how they unfold. Science correspondent Miles O’Brien reports. Continue reading

    Over the weekend, astronauts aboard the orbiting International Space Station added a module like none other. Think an RV that expands out the back with extra space for sleeping quarters. In the case of the ISS, it was an inflatable Bigelow Expandable Activity Module (BEAM). It’s made of a material stronger than kevlar and could be a game-changer. Science correspondent Miles O’Brien reports. Continue reading
