Cities across the world should invest holistically to meet today’s changing mobility needs and create urban landscapes more accessible and sustainable.
Miniaturizing night vision could therefore lead to widespread adoption. Creating night vision filters that weigh less than a gram and can sit as a film across a pair of traditional spectacles opens up new, everyday applications.
Consumer night vision glasses that allow the user to see the visible and infrared spectrum at the same time could result in safer driving in the dark, safer nighttime walks, and less hassle working in low-light conditions that currently require bulky and often uncomfortable headlamps.
In research published in Advanced Materials, TMOS researchers from the Australian National University demonstrate enhanced infrared vision non-linear upconversion technology using a non-local lithium niobate metasurface.

Analysis of two major cosmic blasts deepens the mystery of where the universe’s ‘heavy’ elements come from.
It sure looks like other philosophers are using the Stone duality in ways that are a lot more sophisticated than my own way!
Abstract In this paper we present a point-free theory of Whiteheadean style of space and time.
In this paper we present a point-free theory of Whiteheadean style of space and time. Its algebraic formulation, called dynamic contact algebra (DCA), is a Boolean algebra whose elements symbolized dynamic regions changing in time, with two spatio-temporal mereotopological relations between them: stable and unstable contact. We prove several representation theorems for DCAs, representing them in structures arising from products of contact algebras or from products of topological spaces. We also present a decidable quantifier-free constraint logic for reasoning about stable and unstable mereotopological relations between dynamic regions. We consider the paper as a first step in point-free dynamic mereotopology.

NASA’s Chandra X-ray Observatory detects X-ray emissions from astronomical events.
Researchers at the University of California, Los Angeles (UCLA) have achieved a significant milestone in optical imaging technology. A new all-optical complex field imager has been developed, capable of capturing both amplitude and phase information of optical fields without the need for digital processing.
