Researchers 3D print biomedical parts with supersonic speed — ScienceDaily

Forget glue, screws, heat or other traditional bonding methods. A Cornell University-led collaboration has developed a 3D printing technique that creates cellular metallic materials by smashing together powder particles at supersonic speed. This form of technology, known as “cold spray,” results in mechanically robust, porous structures that are 40% stronger than similar materials made with […]

Water exists on sunny parts of the moon, scientists confirm

Past observations have suggested that there’s water on the moon. New telescope observations conclude that those findings hold water. Spacecraft have seen evidence of water ice in permanently shadowed craters at the lunar poles (SN: 5/9/16), as well as hints of water molecules on the sunlit surface (SN: 9/23/09). But water sightings in sunlit regions […]

Even the deepest, coldest parts of the ocean are getting warmer

Things are heating up at the seafloor. Thermometers moored at the bottom of the Atlantic Ocean recorded an average temperature increase of about 0.02 degrees Celsius over the last decade, researchers report in the Sept. 28 Geophysical Research Letters. That warming may be a consequence of human-driven climate change, which has boosted ocean temperatures near […]
