    Could Scoop of Moon Dust Reveal Alien Technology? | Sci.News (opens the original)

    Excerpt · English

    Read excerpt

    A cubic meter of lunar soil might be one of our best bets for finding physical proof that another advanced civilization once existed somewhere in the Milky Way, according to a new paper to be published in the International Journal of Astrobiology. Pinault et al. propose searching the Moon for microscopic technosignatures — tiny engineered particles that may have traveled through interstellar space and become preserved within lunar soil over billions of years.

    Mercury’s Crust May Hide Metal beneath Its Surface | Sci.News (opens the original)

    Excerpt · Neutral tone · English

    Read excerpt

    Using a novel laboratory calibration, planetary researchers in Germany have produced the most reliable map yet of silica (SiO2) concentrations across the surface of Earth’s Moon, and a first silica estimate for Mercury. Their study is built around the Christiansen Feature (CF), a spectral signature in the mid-infrared that shifts predictably with a material’s silica content. This colorful view of Mercury was produced by using images from the color base map imaging campaign during MESSENGER’s pri

    Our Ancient Ancestors May Have Climbed Trees with ‘Monkey’ Feet | Sci.News (opens the original)

    Excerpt · Neutral tone · English

    Read excerpt

    An enduring debate in paleoanthropology asks what kind of foot the last common ancestor (LCA) of humans and chimpanzees had: one built like a modern ape’s for climbing straight up trees, or one built more like a generalized monkey’s, less suited to vertical climbing. In new research, paleoanthropologists from Dartmouth College and Ohio State University found that vertically-climbing monkeys called sooty mangabeys (Cercocebus atys) can flex their feet nearly as much as chimpanzees while climbing

    Denisovans Were Surprisingly Tall, New Fossils from Taiwan Suggest | Sci.News (opens the original)

    Excerpt · English

    Read excerpt

    Two fossilized leg bones of Denisovans — an extinct archaic Homo group whose lineage diverged from the Neanderthal lineage 550,000 years ago and was widely distributed across eastern Asia until 45,000 years ago — dredged decades ago from the seafloor off Taiwan indicate that at least some members of the group were remarkably large-bodied.

    224,000-Year-Old Homo Skull Fragment Adds New Mystery to Human Origins | Sci.News (opens the original)

    Excerpt · English

    Read excerpt

    A fossilized skull fragment of Homo sp. unearthed in central Spain offers paleoanthropologists a fresh window into the story of ancient humans who lived in Europe hundreds of thousands of years ago. A Homo heidelbergensis, a Neanderthal and a Cro-Magnon. Image credit: SINC / José Antonio Peñas. The fossil is a fragment of a parietal bone — one of the bones that form the sides and top of the skull. The specimen was found embedded in rock breccia during excavations at the Middle Pleistocene locali
