New York scientists engineer a bacterium that captures air pollutant and releases battery metals
3+ week, 1+ day ago (414+ words) The research fits into a broader push to build climate solutions that generate something valuable instead Cornell scientists have modified a bacterium to accelerate the breakdown of ultramafic rock, speeding up a natural reaction that can support carbon dioxide capture....
Sodium-ion batteries near a key EV milestone, and they may already undercut lithium on price
3+ week, 1+ day ago (524+ words) "It doesn't come with the geopolitical baggage that lithium, nickel, and cobalt do." Two trends are converging for sodium-ion batteries: their energy density is climbing toward levels long associated with lithium packs, while pricing may again be shifting in sodium's…...
Engineered bacteria may speed one of Earth's oldest ways of pulling carbon dioxide from the air
1+ week, 1+ day ago (475+ words) A slow but powerful natural climate process may be getting a high-tech boost as researchers explore whether engineered bacteria can accelerate the breakdown of rocks, potentially speeding a natural pathway that removes carbon dioxide from the atmosphere. On Aug. 28, 2026, Phys....
Fourth-generation LFP batteries pack more into each cell without changing chemistry
1+ week, 6+ day ago (505+ words) It could reduce the amount of space needed for the same amount of stored energy. Fourth-generation lithium iron phosphate batteries could enhance the utility of one of the essential clean-energy tools. The large battery systems that store electricity for later…...
