    Could gravity itself be a future medication? (opens the original)

    Excerpt · Neutral tone · English

    Read excerpt

    Scientists have taken a closer look at what happens to the human genome in simulated microgravity — and found that it is surprisingly resilient, at least over a single day. In a new study, researchers at New York University built a custom random-positioning machine that continually changed the orientation of human cells relative to Earth's gravity. Crucially, the team developed algorithms that minimized the fluid currents normally generated inside rotating cell cultures, allowing it to distingui

    The James Webb Space Telescope is helping astronomers become alien weather forecasters (opens the original)

    Excerpt · Neutral tone · English

    Read excerpt

    With a new analysis of James Webb Space Telescope observations, we're one step closer to interstellar weather forecasting — a baby step, at least. Before astronomers can issue weather forecasts for worlds beyond our solar system, they need to know what drives the atmospheres of those planets and whether their weather follows recognizable patterns. And in a new study based on James Webb Space Telescope (JWST) data, researchers studied SIMP 0136, a world about 20 light-years away, and traced much

    Why do we care so much that Pluto isn't a planet? (opens the original)

    Excerpt · English

    Read excerpt

    Twenty years after Pluto lost its planetary status, people are still arguing about it. This spring, NASA Administrator Jared Isaacman publicly threw his support behind "make Pluto a planet again," reigniting the familiar debate. Social media threads are filled with people arguing over whether Pluto should be grandfathered into the planetary club, whether dwarf planets are simply another kind of planet, and whether the distinction matters at all. The disagreement dates to August 24, 2006, when me

    Scientists just found the fastest known star in the Milky Way. It zooms around our black hole at 15,500 miles per second (opens the original)

    Excerpt · Positive tone · English

    Read excerpt

    Astronomers have found the fastest known star in the Milky Way, a faint object racing around Sagittarius A*, the supermassive black hole at the heart of our galaxy. Dubbed S301, the star reaches about 15,500 miles (25,000 kilometers) per second at its fastest — more than 8% the speed of light. "What is special about this star is that it's orbiting Sagittarius A* on a very tight orbit, taking just 8.7 years to complete it, and is approaching the black hole at a mere 12 times the distance of Earth

    Dinosaur-killing asteroid may have caused firestorms 17 times hotter than the thermal limit lethal to humans (opens the original)

    Excerpt

    Read excerpt

    The dinosaurs may not have starved through a years-long winter. New evidence suggests a blanket of ultrafine impact dust set the planet on fire within hours.
