360-degree head-up display view could warn drivers of road obstacles in real time

Researchers have developed an augmented reality head-up display that could improve road safety by displaying potential hazards as high-resolution three-dimensional holograms directly in a driver’s field of vision in real time. Current head-up display systems are limited to two-dimensional projections onto the windscreen of a vehicle, but researchers from the Universities of Cambridge, Oxford and … Read more

Curiosity captures a martian day, from dawn to dusk

Credit: Pixabay/CC0 Public Domain When NASA’s Curiosity Mars rover isn’t on the move, it works pretty well as a sundial, as seen in two black-and-white videos recorded on Nov. 8, the 4,002nd Martian day, or sol, of the mission. The rover captured its own shadow shifting across the surface of Mars using its black-and-white Hazard-Avoidance … Read more

The future of canine stem cell therapy: unprecedented, painless, and feeder-free

Dog owners may need to learn to appreciate their best friend’s urine. Scientists at Osaka Metropolitan University have devised an efficient, non-invasive, and pain-free method to reprogram canine stem cells from urine samples, bringing furry companions one step closer to veterinary regenerative treatment. Induced pluripotent stem cells (iPSCs) have been widely employed in studies on … Read more

Geometric origin of intrinsic dark counts in superconducting nanowire single-photon detectors

To probe the spatial information of dark counts, we introduced the differential readout method, which utilizes two identical readout channels for tracing the output signals produced by the same dark count event. Two bias-tees (Mini-Circuits, ZX86-12G-S + ) were applied to separate the bias current and output signals. The signals from the two different terminals … Read more

Inside the matrix: Nanoscale patterns revealed within model research organism

Species throughout the animal kingdom feature vital interfaces between the outermost layers of their bodies and the environment. Intricate microscopic structures — featured on the outer skin layers of humans, as one example — are known to assemble in matrix patterns. But how these complex structures, known as apical extracellular matrices (aECMs) are assembled into … Read more
