Some of your cells are not genetically yours — what can they tell us about life and death?

A tiny population of cells that are passed across the placenta between mother and baby challenge basic tenets of human immunology.

Scientific conferences are leaving the US amid border fears

Some meetings have been put on hold in response to foreign researchers’ travel concerns.

Huge reproducibility project fails to validate dozens of biomedical studies

Unique reproducibility effort in Brazil focuses on common methods rather than a single field ― and prompts call for reform.

High time to tackle drug-resistant fungal infections

To combat long-overlooked fungal pathogens, researchers and regulators must embrace innovative science and policy.

Aspirin prevents metastasis by limiting platelet TXA2 suppression of T cell immunity - Nature

Inhibition of cyclooxygenase 1 releases T cells from immunosuppression by platelet-derived thromboxane A2, thereby enhancing the immune response against metastasis.

Functional and structural reorganization in brain tumors: a machine learning approach using desynchronized functional oscillations - Communications Biology

A multimodal MRI study analyzes how signals within brain tumors shape the organization of brain networks and predict surgical outcomes with simple machine learning methods.

Earlier collapse of Anthropocene ecosystems driven by multiple faster and noisier drivers - Nature Sustainability

Current models, based on incremental changes in a single stress, have limited ability to anticipate abrupt ecosystem changes due to climate and human activities. Experiments on four models simulating ecosystems with a range of anthropogenic interactions show how much earlier abrupt change can happen.
