Exclusive: Mira Murati’s Stealth AI Lab Launches Its First Product
Thinking Machines Lab, led by a group of prominent former OpenAI researchers, is betting that fine tuning cutting-edge models will be the next frontier in AI.

Tansania weiter komplett offline, Ausgangssperre in der Hauptstadt
Seit einem Tag kommen die Menschen in Tansania nicht mehr ins Internet. Offenbar wird landesweit protestiert, in der Hauptstadt galt eine Ausgangssperre.

Latent Thinking Optimization: Your Latent Reasoning Language Model Secretly Encodes Reward Signals in its Latent Thoughts
Large Language Models (LLMs) excel at problem solving by generating chain of thoughts in natural language, but such verbal thinking is computationally costly and prone to overthinking. Recent work instead proposes a latent thinking architecture Huggin-3.5B, which represents intermediate reasoning steps as sequence of latent representations. However, latent thoughts lack interpretability and are difficult to supervise, raising concerns about the correctness and reliability of its latent thinking…

Cosmological tensions in the era of precision cosmology: Insights from Tensions in Cosmology 2025
The ``Tensions in Cosmology'' series of conferences has been established as one of the main venues where the cosmological community collectively assesses the cracks in the concordance model and explores possible theoretical and observational remedies. The 2025 edition, held once again in Corfu, Greece, came at a crucial time: the Hubble constant $H_0$ discrepancy has now exceeded $6σ$, and new high-precision data from DESI, JWST, ACT, and other facilities have made this tension more robust whi…

The International Max Planck Research School for Solar System Science becomes a permanent institution in Göttingen and Braunschweig
The Solar System School, the joint graduate school of the Max Planck Institute for Solar System Research, the University of Göttingen, and the Technical University of Braunschweig, is now a permanent fixture in doctoral training in Göttingen and Braunschweig. The Max Planck Society will continue the International Max Planck Research School for Solar Syste…

One of the worst years evarrrrr.

Will the rubbish soon amass on the streets of Duisburg?
The local #H2 station is closing down, meaning the fuel cell trucks won't be able to make their rounds to the incinerator.
Think of all the money that has been wasted on hydrogen for mobility. And now the waste trucks will be a waste, too.

Kein Wasserstoff mehr: Müllfahrzeuge können nicht mehr in Duisburg tanken
„Höchst ärgerlich“ findet Thomas Patermann die Schließung der einzigen öffentlichen Wasserstoff-Tankstelle in Duisburg. Das Archivbild zeigt den Vorstand der Wirtschaftsbetriebe Duisburg (WBD) bei der Vorstellung des ersten Müllfahrzeugs mit Elektroantrieb.

The Hubble tension as an effect of the renormalization of fundamental constants and cosmological parameters
In this Letter we propose an interpretation of the Hubble tension as an effect of the scale-running of cosmological parameters and fundamental constants, as the Newton's constant $G$ and the cosmological constant $Λ$. Namely, the tension between $H_0$ measurements by CMB and Supernovae observations would be a consequence of the fact that the value of $H_0$ depends (due to the running of $G$ and $Λ$) on the scale at which it is measured. Indeed, the two different values of the Hubble parameter…

"Digitaler Blackout": Parallel zur Wahl weitgehende Internetblockade in Tansania
In Tansania sind die Menschen in die Wahllokale gerufen, eine richtige Auswahl haben sie nicht. Zeitgleich wurde dann wohl das Internet weitgehend blockiert.
