Teens' ability to consider the intentions of others linked to structural changes in the brain


When it comes to the concept of fairness, teenagers’ ability to consider the intentions of others appears to be linked to structural changes underway in the brain, according to a study. The study is the first to provide evidence linking structural changes with behavioral changes within this context. Understanding the intentions of others is fundamental to human cooperation and how we exist as social beings.

RNAi multiplies its effect in repressing gene expression, structural view suggests


RNAi is a mainstay of contemporary biological research. But how exactly this crucial mechanism functions in humans remains a partial mystery that we are now one step closer to solving. Structural biologists have now published atomic-resolution pictures and a comprehensive analysis of the workings of a part of the RNAi machinery in Molecular Cell. They’ve discovered how several parts of the machinery work in concert to tamp down gene expression after the attachment of the machinery to an mRNA copied from a gene.

Structural and functional MRI in children resuscitated after drowning pinpoints site of anoxic brain injury


Structural and functional MRI in children resuscitated after drowning pinpoints the site of anoxic brain injury to regions controlling movement, while providing strong evidence that networks controlling perception and cognition remain largely intact.

Aphasia recovery via speech therapy related to structural plasticity of the ventral stream


Strengthening the inferior longitudinal fasciculus (ILF) via speech therapy is associated with significant semantic error reductions in aphasic stroke patients, report investigators. These findings suggest that speech recovery is related to the structural plasticity of the residual language network, that semantic skills are integrated by the ILF and that strengthening the ILF is possible with therapy.
