Good article. New physics experiments concerning "cosmic entropy", dark matter, and information theory will be coming up. (Is gravity an emergent phenomenon?)

Is gravity a new type of force that arises from cosmic entropy?
Decades ago, a renegade physicist suggested that gravity isn't so much a force as just a byproduct of the universe's tendency to get more disordered. Now this idea might finally be testable

Absorbing Markov Chain-Based Analysis of Age of Information in Discrete-Time Dual-Queue Systems
Status update systems require the timely collection of sensing information for which deploying multiple sensors/servers to obtain diversity gains is considered as a promising solution. In this work, we construct an absorbing Markov chain (AMC) to exactly model Age of Information (AoI) in a discretetime dual-queue (DTDQ) status update system with generate at will (GAW) status updates, discrete phase-type (DPH-type) distributed service times and transmission freezing. Specifically, transmission i…

State of Europe’s environment not good: threats to nature and impacts of climate change top challenges
Significant progress has been made in reducing greenhouse gas emissions and air pollution, but the overall state of Europe’s environment is not good, especially its nature which continues to face degradation, overexploitation and biodiversity loss. The impacts of accelerating climate change are also an urgent challenge, according to the European Environment Agency’s (EEA) most comprehensive, ‘state of environment’ report, published today. The outlook for most environmental trends is co…

Discrete quantum group coaction on the circle
We prove by an explicit calculation that if any Kac-type discrete quantum group $\mathcal{Q}$ has a faithful coaction on $C(S^1)$ which is `linear' in the sense that it leaves the space spanned by $\{ Z, \overline{Z} \}$ invariant, then $\mathcal{Q}$ must be classical, i.e. isomorphic with $C_0(Γ)$ for some discrete group $Γ$. This parallels the well-known result of non-existence of genuine compact quantum group symmetry obtained by the first author and his collaborators ([32] and the referen…

The type I dichotomy for two-step nilpotent locally compact groups
We address the type I dichotomy for two-step nilpotent locally compact groups. Invoking work of Baggett-Kleppner, we characterize the closed points of the unitary dual of such a group $G$ purely in terms of the group structure. An algebraic criterion characterizing when $G$ is a type I group is derived. We show that this criterion automatically holds if $G$ is a central extension of vector groups over a non-discrete locally compact field $k$ such that the commutator map is $k$-bilinear. As an a…
