Microbes Could Help Extract Nickel for Electric Vehicle Batteries
A new process using microbes to extract nickel from lower-quality ore is being tested at the Eagle Mine in Michigan's Upper Peninsula, potentially extending the life of the only active nickel mine in the United States, according to MIT Technology Review. The mine, owned by an unnamed company, is nearing the end of its operational life as nickel concentrations decline.
The innovative approach involves a fermentation-derived broth developed by the startup Allonnia. This broth is mixed with concentrated ore to capture and remove impurities, allowing for nickel production from ore that would otherwise be unusable. "The process allows nickel production from lower-quality ore," MIT Technology Review reported.
Kent Sorenson, Allonnia's chief technology officer, stated that this method could help companies continue operating sites that have declining nickel quality. The test is currently underway in a pair of shipping containers installed at the mine's mill.
In other news, the annual meeting of the American Economic Association (AEA) took place in Philadelphia a few weeks prior to February 3, 2026, according to NPR News. Economists debated pressing questions, including economic opportunity in the U.S.
Nature News issued a correction to an article published on May 31, 2023, regarding the coupling of tropical water and interannual CO2 growth rate. The correction addressed a misapplication of the Wilcoxon signed-rank test, which resulted in slightly larger P values than initially reported.
Nature News also published research on Thetis cells (TCs), a recently identified lineage of antigen-presenting cells. The research identified a population of RORγt progenitors, termed Thetis-Lymphoid Tissue inducer progenitors (TLP), that give rise to the immediate TC progenitor (TCP) and the Lymphoid Tissue inducer progenitor (LTiP). The study sheds light on the ontogeny of TCs and the factors shaping their abundance and heterogeneity.
Mistral AI, according to MIT Technology Review, partners with global industry leaders to co-design tailored AI solutions. Their methodology involves identifying an "iconic use case" to set the blueprint for future AI solutions. They work with companies like Cisco, Stellantis, and ASML to customize AI systems for specific challenges and goals.
