The digital ecosystem of the Helmholtz Earth & Environment DataHub features fully automatic ingestion technologies for time series data, joint data interfaces, such as the OGC SensorThings API, a joint metadata schema and powerful clients, such as the Earth Data Portal..

A robust digital infrastructure, built upon overarching frameworks and software tools, is essential for the ongoing digital transformation in materials science and engineering. This user journey demonstrates the seamless integration of distinct technical solutions for data handling and analysis, enabling (a) the pursuit of a specific scientific question and (b) adherence to FAIR principles.

We provide the first method allowing to retrieve spaceborne SIF maps at 30 m ground resolution with a strong correlation (r$^2$ = 0.6) to high-quality airborne estimates of sun-induced fluorescence (SIF) ̇SIF estimates can provide explanatory information for many tasks related to agricultural management and physiological studies. While SIF products from airborne platforms are accurate and spatially well resolved, the data acquisition of such products remains science-oriented and limited to temporally constrained campaigns [...]

To study how the human brain works, we need to explore the organization of the cerebral cortex and its detailed cellular architecture. We introduce CytoNet, a foundation model that encodes high-resolution microscopic image patches of the cerebral cortex into highly expressive feature representations, enabling comprehensive brain analyses. [...]

MINDset is a research initiative focused on organizing and integrating multimodal data — including PET, MR, EEG, omics, and cognitive assessments — for precision psychiatry. It establishes a centralized, secure, and standardized database using the BIDS format and adheres to FAIR data principles [...]

Spin-gapped metals have recently emerged as promising candidates for spintronic and nanoelectronic applications, enabling functionalities such as sub-60 mV/dec switching, negative differential resistance, and nonlocal spin-valve effects in field-effect transistors. Realizing these functionalities, however, requires a deeper understanding of their magnetic behavior, which is governed by a subtle interplay between localized and itinerant magnetism. [...]

Sulfite oxidase (SOX) deficiency is a rare inborn error of cysteine metabolism resulting in severe neurological damage. In patients, sulfite accumulates to toxic levels, causing a rise in the downstream products S-sulfocysteine, which mediates excitotoxicity, and thiosulfate, a catabolic intermediate/product of hydrogen sulfide (H2S) metabolism. [...]
