DDR4, the memory standard from 2014, is suddenly in demand again because DDR5 prices have climbed. One example: a 32GB DDR5 kit now costs about $620, while a DDR4 kit costs $260. Gigabyte says upcoming Intel and AMD motherboards will support the older memory so buyers can pair new processors with cheaper RAM.

In macular degeneration, the light-sensing cells in the eye die but the rest of the retina's circuitry survives. The Prima system uses camera glasses and a pocket processor to convert video into near-infrared light, which a 378-pixel implant turns into electrical signals for the retina; the implant also powers itself like a solar cell. Over 80 percent of recipients could read again.

Quantum computers make frequent errors, so they need special states, called magic states, to run the gates that give them their power. The usual way to make those states can eat up most of the machine. Google researchers instead encoded one rough magic state on their Willow chip, checked it without destroying it, and grew it across more qubits, cutting errors about 40-fold.

Industrial robots usually stay bolted in place behind safety fences, repeating one task, so older rules did not cover machines that walk among people. South Korea has approved a pilot where 20 two-legged Robros humanoids clean chip components, place auto parts, stack shipyard material and move logistics packaging alongside workers. Companies must assess risks, and the data will shape future safety standards.

Stargardt disease kills the eye's light-sensing cells while the inner retina that signals the brain survives. Science Corporation's PRIMA is a two-millimeter chip placed at the back of the eye that acts like artificial photoreceptors, receiving images from camera-equipped glasses. The first Stargardt patient received it in a trial in Australia and later read a word in rehabilitation.
