In a world first, Brazilians will soon be able to sell their digital data
Brazil is piloting dWallet, that lets citizens earn money from their data, but experts warn it could deepen inequality.

The Trump administration has dealt a sharp blow to work on H.I.V. vaccines, terminating a $258 million program whose work was instrumental to the search for a vaccine.
Officials from the H.I.V. division of the National Institutes of Health delivered the news on Friday to the program’s two leaders, at Duke University and the Scripps Research Institute.
Both teams were collaborating with numerous other research partners.
The work was broadly applicable to a wide range of treatm…

Trump Administration Ends Program Critical to Search for an H.I.V. Vaccine
The termination is the latest in a series of cuts to H.I.V. research and programs to prevent the disease.

@ddayen.bsky.social @… This kind of "public participation" is what nimbys rail against. It's *anti-democratic* because opponents use it to frustrate the will of the majority.
What both sides of the "abundance" debate miss is that in practice you can do this to transit & infill housing but no…

Rivera Proposal Would Slow Down Seattle Light Rail Permitting - The Urbanist
# Councilmember Maritza Rivera's last-minute proposal would require additional public outreach and documentation for light rail permit applications. The underlying bill had been intended to cut red rape. After pushback from Councilmembers Rinck and Strauss, the vote was delayed a week.

Interpolating Feigin-Frenkel Duality at the Critical Level to Matrices of Complex Size
In this paper, we extend Feigin-Frenkel duality at the critical level to the setting of complex rank. This is accomplished by considering the center of a vertex algebra in Deligne's interpolating categories, along with Feigin's Lie algebras of complex rank, $\mathfrak{gl}_λ$ and $\mathfrak{po}_λ$. More precisely, we define the universal affine vertex algebras associated with Lie algebras in $\underline{\mathrm{Re}}\mathrm{p}(\mathrm{GL}_α,\mathbb{F})$, $\underline{\mathrm{Re}}\mathrm{p}(\mat…

Dold coefficients of quasi-unipotent homeomorphisms of orientable surfaces
The sequence of Dold coefficients $(a_n(f))$ of a self-map $f\colon X \to X$ forms a dual sequence to the sequence of Lefschetz numbers $(L(f^n))$ of iterations of $f$ under the Möbius inversion formula. The set ${\mathcal AP}(f) = \{ n \,\colon\, a_n(f) \neq 0 \}$ is called the set of algebraic periods of $f$. Both the set of algebraic periods and sequence of Dold coefficients play an important role in dynamical systems and periodic point theory. In this work we provide a description of sur…

I'm increasingly preferring individuals’ blogs over corporate blogs for accessibility guidance, even when those corporations are meant to be accessibility-focused.
SEO chasing and consumer funneling really dilute the usefulness of articles, it turns out.

The second order Huang-Yang approximation to the Fermi thermodynamic pressure
We consider a dilute Fermi gas in the thermodynamic limit with interaction potential scattering length $\mathfrak{a}_0$ at temperature $T>0$. We prove the 2nd order Huang-Yang approximation for the Fermi pressure of the system, in which there is a 2nd order term carrying the positive temperature efffect.Our formula is valid up to the temperature $T<ρ^{\frac{2}{3}+\frac{1}{6}}$, which is, by scaling, also necessary for the Huang-Yang formula to hold. Here, $T_F\simρ^{\frac{2}{3}}$ is the Fermi…
