Trillions of synapses in the human brain enable thought and behavior. Synaptic connections must be established and maintained, while retaining dynamic flexibility to respond to experiences. These processes require active remodeling of the synapse to control the composition and integrity of proteins and organelles.

However, few studies have explored outdoor free play among autistic preschoolers in natural settings from a neurodivergent-informed perspective.
Objective: To explore the play preferences, opportunities, and challenges in outdoor play for autistic preschoolers.
Autophagy modulates synaptic function and plasticity, but the molecular basis for this process is largely unknown. A recent tour de force study by Overhoff and colleagues identifies a novel role for autophagy in regulating PKA signaling at synapses to modulate the organization of the postsynaptic proteome and neuronal excitability.

We have identified three cell types that regulate aggression in Drosophila: one type is sexually shared, and the other two are sex specific.

The p53-ARF-MDM2 pathway is deregulated in 84% of glioblastoma (GBM) patients and 94% of GBM cell lines.
