MIT advances photonic links to petabit-speed data transfer

MIT's FUTUR-IC program unveils advances in electronically-photonic integration to push data transmission toward and beyond one petabit per second with lower energy use, including evanescent and GRIN optical couplers plus a third previously developed one—optical 'solder bumps' linking photonic devices. These approaches can be manufactured with existing semiconductor equipment, and Earthster models environmental impact while the initiative trains a workforce for semiconductor efficiency. The aim is to separate computation (electronics) from communication (photonic) to reduce data-center energy as AI and cloud services scale.

MIT's Y-Zipper Turns Flexible Strips Into Rigid Beams

MIT's CSAIL has turned Bill Freeman's 1985 three-sided zipper idea into a practical device: a 3D-printed, reversible Y-Zipper that links three flexible strips into a rigid, load-bearing triangle when zipped, with software-driven customization for length, bend, and motion modes, enabling rapid deployment in camping gear, medical devices, robotics, space, and disaster relief.

Engineer's instinct: Lisa Su urges MIT graduates to tackle hard problems together in the AI era

In her MIT Class of 2026 remarks, Lisa Su recalls her journey from MIT to IBM and AMD, praises UROP and the ‘mind and hand’ ethos, and argues AI will accelerate discovery but must be guided by people with purpose and judgment. She urges graduates to chase hard problems with teamwork and an engineer’s instinct, and to recognize that luck plays a role in turning ambitious ideas into reality.

MIT researchers unveil a low-energy, circular process to extract lithium from hard rock

MIT researchers have developed a room-temperature, low-energy, closed-loop method that dissolves spodumene using an ammonium fluoride-water mix to release lithium, aluminum, and silica, with reagents recovered for reuse to nearly zero waste. The process could halve hard‑rock lithium extraction costs and be competitive with brine methods, demonstrated across 17 spodumene sources and moving toward commercialization via Rock Zero (MIT spinout); the work, published in Science, aims to boost onshore critical-mineral supply for batteries.

MIT's Physics-Based Virtual Violin Lets Designers Hear Changes Before Crafting

MIT researchers built a physics-based computational violin that simulates realistic violin sound by modeling how vibrating strings interact with air, enabling luthiers to audition design changes (wood type, back-plate thickness) virtually before building. The current model handles pizzicato; bowing is more complex and will come later, representing the first physics-based foundation for violin sound.

Titan’s lakes could host 10-foot, slow-moving waves, new model suggests

MIT researchers’ PlanetWaves model, which accounts for gravity, atmospheric pressure and liquid properties, predicts Titan’s methane/ethane lakes could produce waves around 10 feet tall even with light winds, thanks to Titan’s low gravity and the fuel-like liquids; the model was calibrated with Lake Superior data and then applied to other worlds, offering insights for future probes that might float on Titan’s seas.

MIT’s JWST-Powered Detect-and-Track System Aims to Shield Space Infrastructure

MIT researchers unveil a JWST-based method to detect and track decameter-scale asteroids that are too faint for ground-based telescopes, enabling earlier threat assessment to protect satellites and space infrastructure; the approach, demonstrated with asteroid 2024 YR4, is part of a broader planetary-defense effort that leverages collaborations with observatories like Vera Rubin and MIT facilities to accelerate detection-to-mitigation.

MIT researchers chart a nuclear-powered route to faster Mars voyages

MIT researchers, with NASA backing, are advancing nuclear thermal propulsion to drastically reduce Mars travel time by heating propellant with nuclear energy; Hampson models a full engine’s thermodynamics and neutronics, addresses startup/shutdown cooling challenges, and leverages the MIT Reactor for fuel testing as NASA eyes crewed Mars missions in the 2030s.

MIT’s Biodegradable Capsule Confirms Medication Ingestion in Real Time

MIT engineers have developed a biodegradable ingestible capsule with a zinc-cellulose antenna and a micro-RFID chip that emits a real-time signal confirming a pill has been swallowed. The capsule dissolves in the stomach while the RFID component is excreted, enabling noninvasive adherence monitoring for critical therapies (e.g., transplant immunosuppression) and potential integration with health records. The SAFARI project uses safe, eco-friendly materials and aims for human trials, offering a pathway to real-time feedback without bulky wearables.
