Headline says "Dark roasted and dangerous: Everything you should know about caffeine intoxication"
implying something about dark roasted coffee is dangerous (which might very well be, but you'll see that's not my point here). So, I go into the article but find it has nothing do with roasting, let alone dark roasting.
In fact, the words "dark" and "roast" appear exactly once in the article, and that's in the headline. 😠

Communication Compression for Byzantine Robust Learning: New Efficient Algorithms and Improved Rates
Byzantine robustness is an essential feature of algorithms for certain distributed optimization problems, typically encountered in collaborative/federated learning. These problems are usually huge-scale, implying that communication compression is also imperative for their resolution. These factors have spurred recent algorithmic and theoretical developments in the literature of Byzantine-robust learning with compression. In this paper, we contribute to this research area in two main directions.…

Exact Floquet flat band and heating suppression via two-rate drive protocols
We demonstrate the existence of exact Floquet flat bands implying strong violation of the eigenstate thermalization hypothesis in a large class of closed quantum many-body systems in the presence of a two-rate drive characterized by frequencies $Ω_1$ and $Ω_2=νΩ_1$. We provide the exact analytic condition for this phenomenon to occur for a generic protocol; in particular, $ν=(2p+1)$, where $p$ is an integer, leads to such flat bands for both square-pulse and cosine drive protocols for arbi…

#RustLang is the perfect language for the "move fast, break things" era. No, I'm not implying it encourages you to break stuff. All I'm saying is that all these modern languages are specifically designed for that mindset. They optimize for corporate greed — nicely dressed as "valuing developer's time".
Developers aren't supposed to slow down and think things over. They should finish feature after feature, project after project, profit after profit. When things break, that's bad for profit. However, putting an effort to prevent things from breaking is not cost-effective.
People love to point out memory safety problems with C. However, there are two other important problems affecting C libraries — ABI and API stability. An uncontrolled ABI breakage means that existing programs suddenly breaks. An uncontrolled API breakage means that programs don't build anymore. Combine both and you're in a tight fit.
There are reasonably good solutions to both these problems. However, they require conscious effort, they require thinking — and that is costly. There are also cheap workarounds. If you link libraries statically, you don't need to worry about their ABI changes. If you vendor dependencies, you don't even need to worry about API changes. That's much cheaper for the company — though in reality, it just moves the burden down the line, to distribution developers and users, who end up fighting old, broken or even vulnerable vendored dependencies.
The problem with Rust and #Cargo is that it embraces these hacks into glorified 20M executables. Everything is linked statically, everything is vendored. You can move fast without actually breaking things — at least for the significant majority of users. To the minority, you always have the usual excuse — "we're sorry, we're just volunteers, we can't spend more energy on this, and you should get newer hardware anyway". Not that doing things better wouldn't benefit all users.

JADES - The small blue bump in GN-z11: insights into the nuclear region of a galaxy at z=10.6
We report the detection of continuum excess in the rest-frame UV between 3000 Å and 3550 Å in the JWST/NIRSpec spectrum of GN-z11, a galaxy hosting an active galactic nucleus (AGN) at z = 10.603. The shape of the continuum excess resembles a Balmer continuum but has a break around 3546 Å in the rest frame, which is 100 Å bluewards to the Balmer limit at 3646 Å. A Balmer continuum model alone cannot fit the spectrum, implying a different origin for the continuum excess. The absence of the B…

Probing sterile neutrino freeze-in at stronger coupling
The regime of dark matter (DM) freeze-in at stronger coupling interpolates between freeze-in and freeze-out. It relies on Boltzmann-suppressed dark matter production, implying that the Standard Model bath temperature never exceeds the dark matter mass. In this work, we study this regime in the context of sterile neutrino dark matter, which can be sufficiently long-lived for a tiny sterile-active mixing. The sterile neutrino is assumed to couple to a real singlet scalar, providing for a thermal …

Consequently 4-momentum is defined and conserved only modulo a reciprocal lattice vector of the order of the Planck mass, implying that there is no n…

We prove that generic polynomials in complex two by two matrices factorize, implying that skew parallelogram nets encompass all systems with such a polynomial representation. We demonstrate …

The tidal disruption of planetesimals is a viable source of white dwarf pollution and offers a unique window into the composition of exoplanet systems. The question of how planetary material enters the tidal disruption radius of the white dwarf is currently unresolved. Using a series of $N$-body simulations, we explore the response of the surrounding planetesimal debris disk as the white dwarf receives …

A note on zero density results implying large value estimates for Dirichlet polynomials
In this note we investigate connections between zero density estimates for the Riemann zeta function and large value estimates for Dirichlet polynomials. It is well known that estimates of the latter type imply estimates of the former type. Our goal is to show that there is an implication to the other direction as well, i.e. zero density estimates for the Riemann zeta function imply large value estimates for Dirichlet polynomials.

Conservation Laws For Every Quantum Measurement Outcome
In the paradigmatic example of quantum measurements, whenever one measures a system which starts in a superposition of two states of a conserved quantity, it jumps to one of the two states, implying different final values for the quantity that should have been conserved. The standard law of conservation for quantum mechanics handles this jump by stating only that the total distribution of the conserved quantity over repeated measurements is unchanged, but states nothing about individual cases. …

Where a service falls on such spectra can simply be a consequence of its design, but it can also be a f…

BAL Outflow in Quasar B0254-3327B: Analysis and Comparison with Other Extreme UV Outflows
We have identified a broad absorption line (BAL) outflow in the HST/STIS spectrum of the quasar QSO B0254-3327B at velocity $v=-3200\text{ km s$^{-1}$}$. The outflow has absorption troughs from ions such as Ne VIII, Na IX, Si XII, and Ne V. We also report the first detection of S XIV absorption troughs, implying very high ionization. Via measurement of the ionic column densities, photoionization analysis, and determination of the electron number density of the outflow, we found the kinetic lumi…

Equilibrium tides and magnetic activity in stars with close-by massive planets. The intriguing case of WASP-18
WASP-18 is an F6V star that hosts a planet with a mass of about 10 Jupiter masses and an orbital period of 0.94 days. In spite of its relatively fast rotation and young age, the star remains undetected in X-rays, thus implying a very low level of magnetic activity. To account for such unexpected properties, we propose a mechanism that modifies the internal stratification and the photospheric magnetic activity of a late-type main sequence star with a close-by massive planet based on the action o…
