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.

As SBOMs slowly progress at the federal level and in enterprises, the rise of AI coding assistants is fueling optimistic—and, some experts argue, “kind of insane”—claims about a future with vulnerability-free software.

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.

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.
