Take a look around the airport during your travels this summer and you might spot a string of new technologies at every touchpoint: from pre-arrival, bag drop, and security to the moment you board the plane. In this new world, your face is your boarding pass, your electronic luggage tag transforms itself for each new flight, and gate scanners catch line cutters trying to sneak onto the plane early. It isn’t the future—it’s now.

The vagus nerve is a key communication line between the brain and organs like the heart and lungs—and stimulating it can ease conditions including epilepsy and arthritis. But this electrical therapy often hits the wrong neural fibers, causing side effects like coughing or voice changes. A new study finds that researchers can steer stimulation toward specific fibers and away from others by overlapping high-frequency currents inside the nerve.

In a development straight out of science fiction, Australian startup Cortical Labs has released what it calls the world’s first code-deployable biological computer. The CL1, which debuted in March, fuses human brain cells on a silicon chip to process information via sub-millisecond electrical feedback loops. Designed as a tool for neuroscience and biotech research, the CL1 offers a new way to study how brain cells process and react to stimuli.

Naveen Verma’s lab at Princeton University is like a museum of all the ways engineers have tried to make AI ultra-efficient by using analog phenomena instead of digital computing. At one bench lies the most energy-efficient magnetic-memory-based neural-network computer ever made. At another you’ll find a resistive-memory-based chip that can compute the largest matrix of numbers of any analog AI system yet. Neither has a commercial future, according to Verma.

After the Estonian startup KrattWorks dispatched the first batch of its Ghost Dragon ISR quadcopters to Ukraine in mid-2022, the company’s officers thought they might have six months or so before they’d need to reconceive the drones in response to new battlefield realities. The 46-centimeter-wide flier was far more robust than the hobbyist-grade UAVs that came to define the early days of the drone war against Russia.
