A prognostic human brain network for diffuse midline glioma

Abstract Diffuse midline gliomas (DMGs) are near-universally lethal tumours of the childhood central nervous system1,2. In animal models, DMGs form brain-wide integrated networks through neuron-to-glioma synapses3,4,5,6 and glioma-to-glioma gap junctional coupling3. This extensive connectivity robustly promotes the growth and invasion of DMG3,4,5,6,7,8,9 and other glial malignancies10,11,12 through paracrine mechanisms and direct neuron-to-glioma synapses.

Three key vital signs make up the "urban pulse" of a city

People often speak metaphorically of the heartbeat or pulse of a city, but according to the authors of a new paper published in the Proceedings of the National Academy of Sciences, cities do indeed have an "urban pulse"—an indication of urban "metabolic activity" that can be measured to suss out telltale patterns. And those patterns could help inform future public policy around urban planning. The precise definition of urbanization has shifted over the centuries.

Prototypicality Bias Reveals Blindspots in Multimodal Evaluation Metrics

arXiv:2601.04946v3 Announce Type: replace Abstract: Automatic metrics are widely used to evaluate text-to-image models, often replacing human judgment in benchmarking, model selection, and large-scale data filtering. Yet they may reward images that look plausible or prototypical rather than images that faithfully satisfy the prompt. We identify prototypicality bias as a systematic blindspot in multimodal evaluation: metrics can prefer a semantically incorrect but visually or socially...

Deep learning four decades of human migration

Abstract Human migration is a fundamental driver of global demographic change, shaping population structure, labour markets and social policy across countries1,2,3. Although long-term migration patterns are often linked to economic development4, they can shift rapidly in response to shocks such as conflict, environmental crises and political change5. Despite its importance, migration remains difficult to measure consistently: existing data are sparse, concentrated in high-income settings and...

'You're destroying your countries': Is Europe finally heeding Trump's warning on illegal immigration?

Earlier in June, the European Union appeared to finally react to concerns raised by President Donald Trump and many European voters over illegal immigration by introducing tougher border entry rules for the 27-nation bloc. The EU agreed on new, stricter rules regarding migration and asylum. The laws are specifically designed to ensure that illegal/undocumented migrants who enter the bloc are processed and, where necessary, quickly sent to deportation centers in countries outside the...
