Society should learn to celebrate and capitalise on its
“massive cohort of healthy, active, older, creative adults”,
a leading population expert has said.
While pundits and pressure groups have raised concerns over falling fertility rates, highlighting the challenges for the economy and healthcare,
others are more upbeat, arguing the rise of the “silver economy” brings new opportunities for growth.

Ilford HP5 Plus 400 (FF)

English Alt Text:
A black-and-white photo of outdoor furniture arranged in neat stacks. On the left, two tall columns of plastic stools are nested together, each stool featuring small ventilation holes on top. On the right, a stack of plastic chairs with curved backrests and metal legs leans slightly. The chairs are also nested, forming a compact tower. The ground is paved, and a metal rod lies nearby. In the upper left corner, wooden steps suggest proximity to a build…

A black-and-white photo of a city street scene. In the foreground, a circular traffic sign displays the number “50,” indicating a speed limit of 50 km/h. Below it, a rectangular sign with Chinese characters reads “Shuangjing Bridge – Jingguang Bridge.” The signs are mounted on a pole near a leafy tree. In the background, cars and a motorcycle move along a wide road flanked by buildings, including a high-rise and a long residential block. The grainy te…

English Alt Text:
A monochrome photo of a city skyline shrouded in smog or fog. Several tall buildings are visible, including a striking skyscraper shaped like a twisted column. A green traffic light glows in the foreground, mounted on a pole near streetlights and an overpass. The air appears thick, reducing visibility and softening the outlines of buildings. The image evokes urban density and environmental tension, with a quiet, surreal mood.

English Alt Text:
A black-and-white photo taken from inside a tunnel or underpass, looking out onto a busy urban road. Several people ride scooters or motorcycles, while one person walks along the sidewalk. The road continues under a series of elevated structures supported by thick columns. In the distance, a bus and a car are visible. The tunnel’s shadow frames the scene, creating strong contrasts between light and dark. The photo captures a moment of city life in mot…

Arriving at Act I, The Alters is quite engaging. It's a video game, in case you are reaching for your favourite search engine. So far, the sci-fi aspect has that structured feeling of the Eastern European/Soviet branch of the genre, mixed up with the post-Soviet era shift of values and cultural trends -- still kind of bland, but looking at the Western guilty thrill of the dystopian. It's a damn good, well-made game. I hope it holds up in that way until the end.

The Alters cover art, showing the main protagonist and his many different clones whimsically looking at the camera.

Graphene and thin graphite films for ultrafast optical Kerr gating at 1 GHz repetition rate under focused illumination

arxiv.org/abs/2511.17713 arxiv.org/pdf/2511.17713 arxiv.org/html/2511.17713
arXiv:2511.17713v1 Announce Type: new
Abstract: The ability to address sub-picosecond events of weak optical signals is essential for progress in quantum science, nonlinear optics, and ultrafast spectroscopy. While up-conversion and optical Kerr gating (OKG) offer femtosecond resolution, they are generally limited to ensemble measurements, making ultrafast detection in nano-optics challenging. OKG, with its broadband response and high throughput without phase-matching, is especially promising when used at high repetition rates under focused illumination.
Here, we demonstrate an ultrafast detection scheme using the third-order nonlinearity of graphene and thin graphite films, operating at 1 GHz with sub-nanojoule pulses and achieving 141 fs temporal resolution. Their exceptionally large nonlinear refractive index, orders of magnitude higher than conventional Kerr media, enhances detection efficiency at smaller thicknesses, enables sub-picosecond response, and supports broadband operation. Their atomic-scale thickness minimizes dispersion and simplifies integration with microscopy platforms, optical fibers, and nanophotonic circuits, making them a compact, practical material platform for nano-optical and on-chip ultrafast Kerr gating.
