    Bioresorbable battery reportedly worked for up to three days in pig stomachs

    A science roundup describes a paper-like battery that powered ingestible RFID and stomach-stimulation systems, while noting that not all the electronics can break down after use.

    TLDR

    A user's science roundup says researchers built a paper-like magnesium–molybdenum trioxide battery with a peak voltage of 1.84 volts. It reportedly powered ingestible radio-frequency identification (RFID) and gastric-stimulation systems and remained functional in pig stomachs for up to three days. The post says the battery can disappear after use, but the full electronic system is not yet universally bioresorbable. It identifies human safety and fully bioresorbable electronics as next steps.

    Ryzm@Goeun_6121Science & Tech Daily | September 22, 2026 Seven recent developments worth tracking. 1. RetroChimera makes retrosynthesis AI more chemist-aligned RetroChimera combines models with different inductive biases to improve predictions on rare reactions and unfamiliar chemistry. Organic chemists preferred its suggestions over competing models and published reference reactions, while the system also transferred to internal GSK and Novartis datasets. The next test is prospective chemistry. Expert preference and benchmarks do not yet tell us yield, cost or failure rates in real discovery programs. 2. A bioresorbable battery worked inside pigs for three days Researchers built a paper-like magnesium-molybdenum trioxide battery with a peak voltage of 1.84 V. It powered ingestible RFID and gastric-stimulation systems and remained functional in swine stomachs for up to three days. The battery can disappear after use, but the full electronic system is not yet universally bioresorbable. Human safety and fully transient electronics come next. 3. Real-world EV data still shows a large emissions advantage Researchers analyzed mileage and survival data covering every battery EV in Britain. Current BEVs were projected at about 88 g CO₂e/km over their lifecycle, versus 254–270 g for conventional vehicles and about 190 g for hybrids. The analysis uses real-world driving data, but newer vehicle lifetimes still require modeling and results depend on manufacturing and electricity assumptions. 4. Taiwan is building more infrastructure around advanced packaging Construction began on the 88.7-hectare Baipu Industrial Park in Kaohsiung. TSMC plans a technology-validation lab and training center there, with operations targeted for Q4 2029. Advanced packaging is increasingly part of the AI compute bottleneck, tying logic, HBM and packaging capacity more closely together. For Korea, that matters directly to Samsung, SK hynix and the packaging supply chain. 5. A soft robot can switch between more than nine locomotion modes A six-spoke elastomer robot with liquid-metal channels can roll, crawl, jump, swim and rapidly switch modes. It reached 818 mm/s while rolling and could fold its occupied volume by 79%. Researchers tested it across gelatin, viscous fluids and porcine gastric environments. Autonomous operation inside a living animal, tracking and long-term material safety remain ahead. 6. A phage repairs its DNA after CRISPR cuts it A phage defense system called Healer acts after CRISPR cleavage rather than blocking the attack itself. Gp63 recognizes exposed single-stranded DNA and helps Gp64 drive homologous recombination to repair the viral genome. The mechanism adds another layer to the bacteria-phage arms race. Its prevalence in nature and usefulness for engineered phages still need testing. 7. Mining overlaps heavily with conservation priorities Researchers mapped about 145,000 km² of current mining land against conservation zones and species ranges. Roughly 34%, or 49,000 km², overlapped priority conservation areas and intersected the ranges of more than 2,300 species. Many minerals needed for the energy transition also sit inside this tension. The maps are better used as an early-warning tool for permitting, sourcing and recycling than as automatic no-mining zones. Today’s line Several of today’s technologies are moving closer to operational reality. AI is being judged by chemists. Batteries are working inside animals. Robots are entering biological environments. Semiconductor infrastructure is being built around packaging. The next bottleneck is evidence at scale.23d
