Hab mich mal umgehört, ob das, was #Gotham von #Palantir demnächst für die Polizei in #BadenWürttemberg tun soll, wirklich so alternativlos ist, wie es von einigen dargestellt wird.

Palantir-Software "Gotham" bei der Polizei in der Kritik: Können BW-Unternehmen den Streit lösen?
Die Polizei in BW soll bald die Software "Gotham" von Palantir einsetzen. Doch es gibt Kritik - unter anderem an Firmen-Mitgründer Peter Thiel.

Das war ein wirklich beeindruckender Vortrag von @… über Geschichte und Zukunft unseres Planeten und des Weltalls im #Planetarium #Stuttgart. Ich habe gleich das Buc…

Scientists have a dire new warning about the state of the planet
Recent climatic developments "mark the beginning of a grim new chapter for life on Earth," but it's not too late for radical action.

Understanding the Origins of Super-Puff Planets: A New Mass-Loss Regime Coupled to Planetary Evolution
Super-puffs are a class of low-mass, large-radius planets that have challenged planet formation and evolution models. Their high inferred H/He mass fractions, required to explain their physical sizes, would lead to rapid atmospheric escape, raising questions about their long-term retention. Recent modeling work indicates that low-mass planets typically require 50\% less H/He mass to match their observed radius, due to significant roles of the radiative atmosphere and interior heating from the r…

We've done the science—let's get on with climate action
For three decades now, I have watched Earth warm—not through headlines or politics, but in my own data. Every year, the evidence has become clearer. My colleagues have measured rising CO₂ levels in Antarctic ice cores. We have seen ice caps retreat, permafrost melt, ecosystems shift, and species vanish. Every single working day of my life has been a front-row seat to a planet in rapid transformation.

"In Al-Mughayyir, a village near Ramallah, more than 3,000 olive trees were bulldozed by Israeli forces, part of a broader pattern of destruction. Similarly, Deir Ballout has been targeted once again. It’s where, in 2021, Zaytoun customers helped plant 2,000 olive trees with the Palestine Fair Trade Association to replace those previously destroyed by Israeli forces."

Olive Harvest 2025: a season of hope, struggle, and solidarity - Zaytoun
As the olive harvest commences this month, the outlook is grim. A number of forces are converging in real time: a poor harvest, soaring local prices, and a fragile economy already on the brink, all dealing a harsh blow to farmers who are contending with so much.

The Influence of Cold Jupiters in the Formation of Close-in planets. II. Collisional Growth of Planetesimals
Exoplanet observations have shown that the occurrence and orbital architectures of close-in super-Earths and sub-Neptunes are shaped by the presence of outer gas giant planets. This influence may emerge during the formation stage or from later dynamical evolution by a yet elusive physical process. In this work, we investigate the early stages of planetesimal accretion, modeling the joint collisional and dynamical evolution of planetesimals under the gravitational influence of a cold Jupiter and…

Multi-band Spectral and Astrometric Characterization of the HIP 99770 b Planet with SCExAO/CHARIS and Gaia
We present and analyze follow-up, higher resolution ($R$ $\sim$ 70) $H$ and $K$ band integral field spectroscopy of the superjovian exoplanet HIP 99770 b with SCExAO/CHARIS. Our new data recover the companion at a high signal-to-noise ratio in both bandpasses and more than double the astrometric baseline for its orbital motion. Jointly modeling HIP 99770 b's position and the star's astrometry from \textit{Hipparcos} and \textit{Gaia} yields orbital parameters consistent with those from the disc…
