A new peer reviewed study is challenging one of the most widely shared claims about Yellowstone’s wolves. In a formal comment published in Global Ecology and Conservation, scientists from Utah State University and Colorado State University argue that a 2025 paper by Ripple et al. overstated how much wolf recovery reshaped Yellowstone National Park’s ecosystem.
Four crew members of NASA’s SpaceX Crew-12 mission launched at 5:15 a.m. EST Friday from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida for a science expedition aboard the International Space Station. A SpaceX Falcon 9 rocket propelled a Dragon spacecraft into orbit carrying NASA astronauts Jessica Meir and Jack Hathaway,
Last year, physicists created a time crystal—atomic arrangements repeating motion patterns—visible to the naked eye. But the latest research on this quantum eccentricity might represent more than a few steps forward. This time crystal, described in a recent Physical Review Letters paper, is big enough to be held in your hand, and it levitates. Discovered
Starship nearing next test flight. The upgraded Super Heavy booster slated to launch SpaceX’s next Starship flight has completed cryogenic proof testing, clearing a hurdle that resulted in the destruction of the company’s previous booster, Ars reports. The proof test is notable because it moves engineers closer to launching the first test flight of an
You know that feeling when everyone tells you something is impossible, so you never even try? That is what happened in chemistry for a hundred years. Students memorized a rule, one called Bredt’s rule, and then everyone obeyed it. Professors taught it. Nobody questioned it. And it was wrong. The team of chemists
Residents of several Midwestern U.S. states were treated to a dramatic natural light show in the early hours of Feb. 10, when a fireball meteor made a fiery descent, brightening the winter sky before appearing to disintegrate as it neared the horizon. The meteor‘s fiery passage generated over 120 reports on the American Meteor Society
Massive stars are often known to go out with a bang: The core collapses, and a wave of subatomic particles called neutrinos erupt outward, causing the star to explode as a supernova that can outshine an entire galaxy. But 2.5 million light-years away from Earth, in the Andromeda galaxy, a dying star named M31-2014-DS1 did

When people breathe, speak, sing or clear their throats, their bodies are in constant motion. Air flowing through the lungs, the oscillation of vocal folds in the throat and the rhythmic expansion of the chest all produce tiny vibrations that carry valuable information about physiology and health1. However, constructing a device that can capture all
NASA and Vast have signed an order for the sixth private astronaut mission to the International Space Station, targeted to launch no earlier than summer 2027 from Florida. This private astronaut mission marks the company’s first selection to the orbiting laboratory, underscoring NASA’s ongoing investment in fostering a commercial space economy and expanding opportunities for
