This temporary tattoo could detect an unwanted drug in your drink
Researchers reporting in ACS Sensors have created a temporary tattoo sticker that has a hidden, but possibly lifesaving, purpose: detecting the presence of one drug used to "spike" alcoholic beverages and facilitate sexual assault. The sticker responds within 1 second to even low concentrations of the drug γ-hydroxybutyrate (GHB).

Gödel-type universes in unimodular gravity
In this paper, the Gödel-type universes are examined within the framework of unimodular gravity. Since the existence of Gödel solutions is intrinsically related to the presence of a cosmological constant in general relativity, one can naturally wonder how the acausal structure of the Gödel solutions behaves in different cosmological scenarios. One of the simplest, but important, frameworks within this context is the unimodular gravity, in which the cosmological constant emerges as an integra…

The US commerce department has launched two national security probes that could lead to tariffs on drones and a raw material used for chips and solar panels.
In notices published on Monday evening, the commerce department said it would examine imports of unmanned aircraft systems and their parts and components,
and would separately carry out a study of polysilicon supply chains.
US officials would study the impact of foreign subsidies, “predatory trade practices”

From Explicit Diffeomorphism Breaking to Spontaneous Unimodularization
This contribution investigates modifications of General Relativity that allow or mimic energy nonconservation. We focus on Unimodular Gravity (UG), a theory that explicitly breaks diffeomorphism invariance, and show that it can lead to particle acceleration, opening the door to experimental constraints. We also argue that UG admits a well-posed initial value formulation, despite the presence of nondynamical structures. Finally, we introduce a simple model that spontaneously mimics UG, but in wh…
