What Meta glasses lack is what most excites me about Apple Glasses
When I tried Ray-Ban Meta glasses last week, I described the AI features as largely a gimmick at this point, but still making me feel excited for a future Apple Glasses product. Several commenters noted that the glasses do somewhat better when giv.....»»
New optical tweezers can trap large and irregularly shaped particles
Researchers have developed new optical tweezers that can stably trap particles that are large—about 0.1 mm—and irregularly shaped. While conventional optical tweezers use highly focused laser beams to trap micro- or nano-scale rod shaped or spher.....»»
Scientists create an "optical conveyor belt" for quasiparticles
Using interference between two lasers, a research group led by scientists from RIKEN and NTT Research have created an "optical conveyor belt" that can move polaritons—a type of light-matter hybrid particle—in semiconductor-based microcavities. Th.....»»

Trying Ray-Ban Meta glasses reinforces my belief in future Apple Glasses
I’m on record as saying that I think Vision Pro is mostly a stepping-stone toward an eventual Apple Glasses product, and that I think those are still years away yet. I feel like current glasses tech is giving us these partial peeks into that fut.....»»
Training Today Apple Watch app gains dynamic cycling workouts for more intentional rides
Training Today is a clever app that offers Apple Watch users a “readiness to train” score to help know when to rest, push, and more. Now the watchOS and iOS app have been updated with “dynamic cycling workouts” to train more intentionally on.....»»
More children gain hearing as gene therapy for profound deafness advances
The therapy treats a rare type of deafness, but experts hope it's a "jumping point." Enlarge / Opal Sandy (center), who was born completely deaf because of a rare genetic condition, can now hear unaided for the first time after r.....»»
Parity-time symmetry: Unlocking faster and stronger optical signal processing
In the era of big data, signal processing faces significant challenges in terms of capacity and energy consumption due to the torrent of data to process. With over 90% of data transmitted through light, optical signal processing may offer unprecedent.....»»
Researchers demonstrate low-loss and polarization-independent integrated optical colorless ROADM
The implementation of integrated optical switches shows promise in the size reduction of ROADMs for greater flexibility and compactness, ultimately leading to robust single-chip solutions. Despite decades of research on switches with various structur.....»»
