SWOT Satellite Reveals Global River Models Overstate Water Swings

NASA and France’s CNES space agency have delivered something hydrologists have wanted for decades: a direct, month-by-month accounting of how much water the world’s rivers gain and lose over a full year. During its first observation cycle, running from October 2023 to September 2024, the SWOT satellite logged a swing of roughly 313 cubic kilometers … Read more

MIT’s Breathable Hydrogel Embeds Air Channels to Boost Oxygen Flow Tenfold

MIT engineers have developed a breathable hydrogel that embeds tiny air channels inside its polymer network, increasing oxygen permeability by roughly ten times while preserving the material’s softness. The advance, published in Nature in July 2026, could extend the wear time of medical patches, sensors and bandages that currently suffocate the skin after a few … Read more
