Molecular mechanisms: Microglia abnormal in autism brains
Two new postmortem studies show that microglia, which protect the brain from invaders, are denser and more concentrated around neurons in the brains of individuals with autism than in those of controls.

Immune cells sculpt brain by pruning neuronal connections
Immune cells called microglia may play a central role in trimming synapses, the connections between neurons, according to research published 24 May in Neuron. These modifications are part of a normal developmental process by which excess synapses in the brain are destroyed.

Bone marrow transplant alleviates Rett symptoms in mice
A bone marrow transplant from healthy mice to those lacking the MeCP2 protein, which causes Rett syndrome, extends lifespan and alleviates symptoms of the disorder, according to research published online 18 March in Nature.

The value of blood cells in autism research
Blood from individuals with autism could help researchers identify biomarkers to diagnose the disorder and learn more about related symptoms, such as gastrointestinal complaints, says molecular biologist Valerie Hu.

Scientists capture microglia’s role in brain connectivity
Scientists are changing their minds about the role of microglia, the brain's strongest and most agile soldiers against damage and infection. In healthy brains, microglia help build and eliminate synapses, the junctions between neurons, according to a study published 2 November in PLoS Biology.

Molecular mechanisms: Autism brains show ‘angry’ microglia
A study of postmortem tissue shows that microglia, cells that provide immune protection to the brain, are altered in the brains of individuals with autism.

Emotion research has a communication conundrum
In 2025, the words we use to describe emotions matter, but their definitions are controversial. Here, I unpack the different positions in this space and the rationales behind them—and I invite 13 experts to chime in.

Autism-linked copy number variants always boost autism likelihood
By contrast, varied doses of the same genes decrease or increase the odds of five other conditions, with distinct biological consequences, two new preprints show.

Everything everywhere all at once: Decision-making signals engage entire brain
The findings, gleaned from the most comprehensive map yet of brain activity during decision-making in mice, show that the process is even more distributed than previously thought.
