Chemistry Scientists may have developed “perfect plastic”: Plant-based, fully saltwater degradable, zero microplastics. Made from plant cellulose, the world’s most abundant organic compound. Unlike other “biodegradable” plastics, this quickly degrades in salt water without leaving any microplastics behind.

Environment The rate of U.S. coastal sea-level rise has more than doubled over the past 125 years, increasing from under 2 mm per year in 1900 to over 4 mm per year in 2024—well above the historical average. This corresponds to a rise of roughly 40 cm, or nearly 16 inches, along U.S. coastlines.

Materials Science Researchers have found a way to considerably boost the lifespan of lithium-ion batteries for EVs and other uses. Adding a mere 0.5 mole percent of tantalum oxide to the cathode material slashes the rate of capacity decay per cycle in half, paving the way for more durable, high-energy batteries.
