Neuroscience¶
7 Brain striatum atlas reveals neuron populations relevant to neurological disorders¶
MIT researchers generated a new atlas of striatal neurons identifying 31 neuron subgroups based on gene expression. The atlas reveals populations specifically affected by Huntington's disease, schizophrenia, addiction, and depression, providing a foundation for developing new drug treatments.
- Identified 31 striatal neuron subgroups by gene expression patterns
- Reveals neurons affected by Huntington's disease, schizophrenia, addiction, depression
- Shows why certain striatal neurons more vulnerable to Huntington's
- Single-cell RNA sequencing and related techniques used
- Intended foundation for developing new drug treatments

Climate¶
7 Deep learning maps global methane emissions from space¶
Google researchers developed MAPLE, a deep-learning framework that detects and maps methane emissions globally using satellite data. The system converts raw satellite imagery into actionable climate intelligence and includes a public plume database and visualization tools.
- Model: Methane Analysis and Plume Localization with EMIT (MAPLE)
- Methane warming potential: 30× greater than CO₂ over 100 years
- Methane responsible for ~25% of human-induced warming since industrial era
- Released resources: global plume database, datasets, trained model, inference library
