Tiny robots built with new 3D printing tricks

Two Ph.D. students and their professor have created a 3D printing method to make tiny Delta robots, called microDeltas, overcoming decades-old challenges in building small-scale robots.

Raspberry Pi Pico versus Arduino explained

You get more RAM and performance with Raspberry Pi Pico, but Arduino’s advantage is its low-power design and beginner-friendly environment for projects.

How silicon photonics transforms data transfer

Silicon photonics puts light on silicon chips to send data faster and more efficiently than electrons, helping AI data centres handle huge data loads with less energy.

AI wearable speeds up wound healing

This portable wearable detects wound stages and adjusts treatment accordingly. a-Heal combines AI and a mini camera to identify how a wound is healing and automatically provides medication or electric therapy, mimicking how a doctor would treat it.

Superconductivity confirmed in twisted graphene

By twisting three graphene sheets just right, MIT researchers observed a clear superconducting gap, confirming the unusual superconducting behaviour in magic-angle tri-layer graphene.
