: When the protein binds to a specific element like terbium , it glows green under UV light.
The biggest hurdle was finding these elements. Rare earths are often present in tiny concentrations—parts per billion—making them a "needle in a haystack" to detect without expensive, bulky lab equipment. New sensor able to detect rare earths in acid m...
: It works in highly acidic environments and is as accurate as the "gold standard" laboratory mass spectrometry (ICP-MS), but is potentially portable and far cheaper. Impact: Turning Waste Into Wealth : When the protein binds to a specific
: The sensor uses a protein called lanmodulin , which is nearly a billion times better at binding to rare earths than other metals. : It works in highly acidic environments and
When sulfur-bearing rocks in coal mines are exposed to air and water, they create sulfuric acid. This acid dissolves surrounding minerals, leaching out heavy metals and turning waterways a rust-colored orange. While these streams were once considered dead zones, researchers realized they contained a hidden fortune: like terbium, neodymium, and scandium—critical components for smartphones, electric vehicle batteries, and wind turbines. The Breakthrough: The "Glow" Sensor
