„Made in Europe”? Bei Batterien ist das meist Fehlanzeige. 🪫🇪🇺
Laut einer Studie der Unternehmensberatung Deloitte war Europas Anteil an der weltweiten Batterieproduktion 2024 verschwindend gering: nur 13 Prozent – und selbst diese entfallen zum überwiegenden Teil auf Fabriken chinesischer und südkoreanischer Hersteller.

Elastic Energy Storage Mechanism in Hovering Animal Flight: A Discriminative Method Based on Wing Kinematics
Existing research has yet to reach a consensus on whether and how small flying animals utilize elastic energy storage mechanisms to reduce flight energy expenditure, and there is a lack of systematic and universal methods for assessment. To address these gaps, this study proposes a method to evaluate elastic energy storage capacity based on wing kinematic parameters (flapping amplitude and flapping frequency), grounded in the hypothesis that animals tend to minimize flight energy expenditure. B…

I have been driving, cycling and walking past this old house for years* waiting for it to fail completely but it is still holds up for the most part.

Thickness-Induced Topological Phase Transition Investigated by Helicity Dependent Photocurrent in $α$-Sn/CdTe(110)
$α$-Sn exhibits a rich topological phase diagram, yet experimental methods to tune and distinguish these phases remain limited. Here, we investigated the helicity-dependent photocurrent (HDPC) in $α$-Sn films of varying thickness grown on CdTe(110) by molecular beam epitaxy. The HDPC of the 5 nm $α$-Sn film shows an odd-function dependence on incident angle, whereas that of the 10 and 30 nm films exhibit an even-function dependence. Combined with high-resolution transmission electron microsc…

Strava Voluntarily Drops Lawsuit Against Garmin
 Strava’s multifaceted legal (and social media) attack on Garmin was short-lived. Just 21 days after filing the original patent infringement case, alongside a Reddit post from their executive team attacking Garmin, the company has decided to dismiss the case

When This Reporter Comes Calling, the White House Insults Go Flying
The administration often criticizes journalists, but the treatment of Shirish Dáte, a reporter for HuffPost, stands out.

Long but very good:
"An essay on wank"
It names and identifies one of my least favorite genre of posts – finally I have a proper term for it!
I'm sure I've been guilty of it too in the past, so it's useful for self-regulation, too.

The Unwinnable Arms Race of AI Image Detection
The rapid progress of image generative AI has blurred the boundary between synthetic and real images, fueling an arms race between generators and discriminators. This paper investigates the conditions under which discriminators are most disadvantaged in this competition. We analyze two key factors: data dimensionality and data complexity. While increased dimensionality often strengthens the discriminators ability to detect subtle inconsistencies, complexity introduces a more nuanced effect. Usi…

Reversal of strain state in a Mott insulator thin film by controlling substrate morphology
The V2O3 phase diagram contains two insulating phases and one metallic phase with different lattice structures. The stability of these phases is very sensitive to pressure, offering a mechanism to tune phase transitions by inducing strain in thin films. The most studied source of strain is lattice mismatch between the film and the substrate. In this work, however, we find that the film/substrate thermal expansion mismatch can be made to play a dominant role by modifying the substrate morphology…
