Swiss researchers used state of the art fabrication facilities to miniaturize erbium lasers on to a silicon chip without impacting performance.
Details have emerged about a new critical security flaw impacting PHP that could be exploited to achieve remote code execution under certain circumstances.
The vulnerability, tracked as CVE-2024–4577, has been described as a CGI argument injection vulnerability affecting all versions of PHP installed on the Windows operating system.
According to DEVCORE security researcher, the shortcoming makes it possible to bypass protections put in place for another security flaw, CVE-2012–1823.
DefenseScoop was exclusively briefed on Central Command’s new Desert Sentry commercial solutions opening, in partnership with the CDAO.

In the vast expanse of the cosmos, there is much more than meets the eye. For every kilogram of visible matter in the universe, from the computer on your desk to the distant stars and galaxies, there are 5 kilograms of invisible “dark matter” that permeate our surroundings.
This enigmatic dark matter evades direct observation yet exerts its invisible pull on the visible objects around us.
Fifty years ago, renowned physicist Stephen Hawking proposed a fascinating idea about the nature of dark matter. He suggested that it might consist of a population of black holes that formed in the early stages of the universe, mere moments after the Big Bang.
The pipe dream of carbon capture is one step closer to reality thanks to a Bill Gates-backed startup that is burying bricks made from plants.
The Washington Post detailed a “deceptively simple” procedure by Graphyte to sequester blocks of wood chips and rice hulls, calling it “a game-changer” for the industry, which has been held back by the cost ineffectiveness of other methods.

New camera chip design allows for optimizing each pixel’s timing to maximize signal to noise ratio when tracking real-time visual indicator of neural voltage.
Neuromorphic photonics is an emerging computing platform that addresses the growing computational demands of modern society. We review advances in integrated neuromorphic photonics and discuss challenges associated with electro-optical conversions, implementations of nonlinearity, amplification and processing in the time domain.
