Physicists Find Strong Evidence of Four-Top Quark Production Physicists from the ATLAS Collaboration CERN’s Large Hadron Collider have uncovered strong evidence of the production of four top quarks. This rare process is expected to occur only once for every 70,000 pairs of top quarks created at the Large Hadron Collider. …

ESA’s Trace Gas Orbiter Detects Glowing Oxygen Using data from the NOMAD (Nadir and Occultation for Mars Discovery) ultraviolet and visible spectrometer instrument on board ESA’s ExoMars Trace Gas Orbiter (TGO), a team of researchers has detected green line dayglow emission in the atmosphere of Mars. An artist’s impression of …

NASA Awards Launch Contract for Water-Hunting Lunar Rover For the first time in years, NASA is gearing up to send humans to the Moon. The agency’s Artemis program aims to have boots on the Moon by 2024, but those boots will necessarily be preceded by wheels. VIPER is one of …

Multiple, well-preserved trackways made by large crocodylomorphs, extinct ancestors of modern-day crocodiles, between 110 and 120 million years ago (Cretaceous period) have been found near Sacheon City in South Korea. Surprisingly, the trackways never include handprints and indicate exclusively bipedal walking, a gait not known from fossil crocodylomorph trackways. Bipedal …
