Dissolving magnesium battery powers ingestible medical devices in pig trials

Researchers have developed a bioresorbable magnesium-molybdenum trioxide battery that powers ingestible medical devices for up to three days before safely dissolving in the gastrointestinal tract. Tested in swine, the battery enabled wireless medication tracking and gastric electrical stimulation, offering a non-invasive alternative to surgical implants. The technology aims to eliminate electronic waste and toxic leakage risks associated with conventional batteries, with human clinical trials expected to begin within two years.

"DiskMantler: Shaking Up Hard Drive Disassembly in 8 Seconds"

Garner has introduced the DiskMantler, a device designed to disassemble decommissioned hard drives and separate valuable internal components from the casing by vigorously shaking it for as little as 8 seconds. This aims to reduce e-waste and provide a safer alternative to traditional shredding and melting methods. The company also plans to release the DeMag, a super degausser that demagnetizes HDD disk platters and magnets, making data forensically unrecoverable. These innovations address both environmental and security concerns related to hard drive disposal.

"Revolutionary Method Uses Food Waste Byproduct to Extract Gold Sustainably"

Researchers at ETH Zurich have developed a groundbreaking method to extract gold from old motherboards using food waste byproduct, specifically whey from the cheesemaking industry. The process involves creating a sponge from whey to collect gold from e-waste in an acid bath, followed by high heat to form nuggets. The value of the extracted gold is 50 times more than the cost of the process, making it commercially viable and environmentally sustainable. This innovative technique offers a more sustainable and profitable alternative to current methods, contributing to e-waste recycling and potentially making electronic devices more affordable for consumers.

"Chameleon-Inspired 3D Printing: Infinite Colors from a Single Ink"

Researchers have developed a sustainable 3D-printing technique inspired by chameleons, allowing for the creation of multiple dynamic colors from a single ink by modulating structural color during the printing process. This approach utilizes specially designed crosslinking polymers and UV light to achieve color gradients in the visible spectrum, offering a more vibrant and potentially more sustainable alternative to traditional chemical pigments or dyes. The study, published in the journal PNAS, demonstrates the power of collaboration in designing this molecular-level system.
