The colors of the Cave
Steve Leonard, taken from Markham, Ontario The Cave Nebula (Sharpless 2–155) is an object that features emission, reflection, and dark nebulae. This Hα/OIII/SII image with exposures of 10, 13, and 6 hours, respectively, taken with a 4.5-inch refractor, was processed as a blend of a static Hubble-palette rendition and a dynamic Foraxx-palette combination of channels.

New circuit boards can be repeatedly recycled
Researchers have developed a new PCB that performs on par with traditional materials and can be recycled repeatedly with negligible material loss. Researchers used a solvent that transforms a type of vitrimer — a cutting-edge class of polymer — into a jelly-like substance without damage, allowing solid components to be plucked out for reuse or recycling. With these ‘vPCBs’ (vitrimer printed circuit boards), researchers recovered 98% of the vitrimer and 100% of the glass fiber.

NASA-Led Study Provides New Global Accounting of Earth’s Rivers
The novel approach to estimating river water storage and discharge also identifies regions marked by ‘fingerprints’ of intense water use. A study led by NASA researchers provides new estimates of how much water courses through Earth’s rivers, the rates at which it’s flowing into the ocean, and how much both of those figures have fluctuated […]
