Ministerium greift beim Luftfahrt-Bundesamt durch
Das Referat L6 im Luftfahrt-Bundesamt ist für viele Piloten ein rotes Tuch - an flugmedizinischen Beurteilungen der Abteilung hängen Fliegerkarrieren. Ein Whistleblower-Hinweis bringt das Luftfahrt-Bundesamt (LBA) im September 2025 arg in Bedrängnis. Jetzt folgen Konsequenzen.

Digital Markets Act: EU-Wettbewerbskommissarin wirft USA „Erpressung“ vor
Teresa Ribera, Vizepräsidentin der EU-Kommission, greift die Trump-Regierung scharf an. Diese setze die EU massiv unter Druck, ihre Tech-Regeln abzuschwächen.

In 2023 I became obsessed with videos of dads in cargo shorts waiting in parking lots during Taylor Swift's Eras Tour.
So when she came to town,
I grabbed a camera and headed down to talk to them.
I thought it'd be funny.
It turned out to be something else entirely.

Dirac QNM spectrum from twisted semiclassical gauge theory of gravity
Twisted Abelian gauge theory coupled to a noncommutative (NC) Dirac field is studied in order to infer the quasinormal mode (QNM) spectrum of the fermion matter perturbations in the vicinity of the Reissner-Nordström (RN) black hole. The action functional of the theory is invariant under the truncated NC local $U(1)_{\star}$ gauge transformations that keep the gravitational background intact. The latter, being a classical gravitational background unaffected by the NC local gauge transforma…

First Light for the GRAVITY+ Adaptive Optics: Extreme Adaptive Optics for the Very Large Telescope Interferometer
GRAVITY+ improves by orders of magnitude the sensitivity, sky-coverage and contrast of the Very Large Telescope Interferometer (VLTI). A central part of this project is the development of Gravity Plus Adaptive Optics (GPAO), a dedicated high-order and laser-guide star Adaptive Optics (AO) system for VLTI. GPAO consists of four state-of-the-art AO systems equipping all 8m-class Unit Telescopes (UTs) for the wavefront correction of the VLTI instruments. It offers both visible and infrared Natural…

Black holes in higher-derivative Weyl conformal gravity
We obtain exact black hole solutions for static and spherically symmetric sources in a Weyl conformal gauge theory of gravity. We consider a quadratic gravitational action built from the Weyl tensor within a dilation geometry. In a post-Riemannian formulation, we derive a Weyl conformal action for a scalar-vector-tensor theory, where the scalar degree of freedom originates from the high-curvature terms and the vectorial one stems from the Weyl non-metricity condition. Adopting a static, spheric…

Making LAZY plants stand up: Research reveals new pathway plants use to detect gravity
A study by researchers at the University of Wisconsin–Madison has revealed a previously unknown pathway plants use to detect gravity and orient the direction they grow in. Publishing in Proceedings of the National Academy of Sciences, the study may one day open the door for improvements in crop cultivation.

Upper Limit on the Non-Gravitational Acceleration and Lower Limits on the Nucleus Mass and Diameter of 3I/ATLAS
We use astrometric data on 3I/ATLAS compiled by the Minor Planet Center from May 15 to September 23, 2025, and derive an upper limit on any statistically significant deviation from the best-fit gravity-based trajectory. The residuals imply that the non-gravitational acceleration is smaller than $\sim 3 \times 10^{-10}\,{\rm au\,d^{-2}}$. Based on the total mass-loss rate and outflow speed inferred from JWST data on August 6, 2025, we derive lower limits on the mass and diameter of 3I/ATLAS of $…
