    Planetary Science

    This tiny, sizzling exoplanet could be made of molten iron

    A newly discovered exoplanet that whips around its star in less than eight hours is smaller than Earth, as dense as iron and hot enough to melt.

    Climate

    Climate change could make Virginia’s Tangier Island uninhabitable by 2051

    Tangier Island could be lost to rising seas sooner than previously realized. Whether to save the island or move its residents remains undecided.

    Paleontology

    This dinosaur had a weapon shaped like an Aztec war club on its tail

    The flat and spiky tail club of a newly discovered ankylosaur was unique, even for this often weirdly armored group of dinosaurs.

    The Southern Ocean is still swallowing large amounts of humans’ carbon dioxide emissions

    A 2018 study suggested the ocean surrounding Antarctica might be taking up less CO₂ than thought, but new data suggest it is still a carbon sink.

    A massive 8-year effort finds that much cancer research can’t be replicated

    A project aiming to reproduce nearly 200 top cancer experiments found only a quarter could be replicated.

    Ancient footprints suggest a mysterious hominid lived alongside Lucy’s kind

    A previously unknown hominid species may have left its marks in muddy ash about 3.66 million years ago in what is now East Africa.

    Microbes

    A bacteria-virus arms race could lead to a new way to treat shigellosis

    As bacteria that cause shigellosis evolve to escape a virus, the microbes may become less deadly, a hopeful sign for “phage therapy.”
