NASA scientist Robert Wagner discovered a massive new lunar crater while performing a routine data check on imagery from the Lunar Reconnaissance Orbiter. The impact, likely caused by an object roughly the size of a six-story building sometime between April and May 2024, created a crater 728 feet wide and 141 feet deep, the largest fresh impact site the orbiter has ever recorded.
Researchers applied mass spectrometry-based proteomics to analyze adhesives and glues found on a range of ancient Egyptian artifacts without damaging them, publishing their findings in Science Advances. Alongside expected animal collagens and egg proteins, they identified plant-derived proteins from sesame and moringa (drumstick tree) sources, expanding the known palette of binding materials used by ancient craftspeople.
Scientists at the Technical University of Denmark built a nanolaser small enough to potentially be embedded by the thousands on a single microchip, letting devices transmit data as light rather than electrical signals. The work, led by professor Jesper Mørk with colleagues Meng Xiong and Yi Yu, appeared in Science Advances.
Astronomers using the Hubble Space Telescope have identified a ten-sided cloud formation encircling Saturn's south pole, a counterpart to the long-known hexagon at the planet's north pole. The decagon, detailed in a new Science Advances study, has sides roughly 16,800 kilometers long and sits near a jet stream blowing close to 260 miles per hour, even though the shape itself drifts at less than 6 mph.
Researchers examined a fragment of 'hiroshimaite,' fallout material from the 1945 Hiroshima atomic bombing, and identified a previously unknown alloy composed of seven elements. The discovery, imaged via scanning electron microscope, was published in Science Advances ahead of the bombing's 81st anniversary.
A new study in Science Advances reports that roughly 560 million children under age 10 worldwide now experience at least one additional month of dangerous heat stress annually because of climate change. Researchers led by Rosa Pietroiusti at Vrije Universiteit Brussel used the WetBulb Globe Temperature threshold of 28°C, a standard combining heat, humidity, wind, and cloud cover, to measure how often conditions cross into risky territory for children's health.
