Researchers in China have launched a massive randomised trial to test whether sending direct health reports to parents can curb rising youth weight issues. By shifting focus from general school programmes to targeted family education, the protocol aims to close a massive gap in parental awareness.

Researchers have developed an artificial intelligence that learns to associate stimuli in a remarkably animal-like way. By modelling its network on the two-compartment structure of key brain cells, the AI can acquire numerous associations efficiently, without the task-specific adjustments required by older learning rules.

Scientists have uncovered how a key HIV protein causes neurological damage by turning the brain’s immune cells against its own wiring. Two types of cells, microglia and astrocytes, begin to aggressively 'prune' vital neural connections, or synapses. This over-pruning is surprisingly specific, varying by brain region and the type of cell involved, providing a new understanding of how HIV-related cognitive disorders develop.

Researchers have discovered that the physical orientation of organic molecules on the surface of quantum dots dramatically controls the speed of energy transfer. By engineering a 'face-on' arrangement, they achieved energy flow thousands of times faster than typical setups, creating useful, long-lived energy states in under a nanosecond.

Scientists are scrutinising a family of immune sensors in the brain called endosomal Toll-like receptors (TLRs). In diseases like Alzheimer's and Parkinson's, these TLRs can be both helpful and harmful, sometimes offering protection but at other times driving the very neuroinflammation that worsens brain injury.

Reliance on a single generic reference genome hinders the analysis of complex laboratory cell lines due to extensive genetic variation. A new study demonstrates that using an 'isogenomic' reference—one specifically matched to the experimental cell line—drastically improves the accuracy of sequencing, gene editing, and structural mapping.
