MIT engineers are incorporating the limitations of 3D printers into computer designs, to better control materials’ performance. The approach helps ensure printed structures perform the way they’re intended to in aerospace, medical, and other applications. 

A new study led by the Icahn School of Medicine at Mount Sinai offers one of the most comprehensive views yet of how brain cells interact in Alzheimer’s disease, mapping protein networks that reveal communication failures and point to new therapeutic opportunities. Published online in Cell on September 25, the study analyzed protein activity in brain tissue from nearly 200 individuals. The researchers discovered that disruptions in communication between neurons and supporting brain cells called glia—specifically astrocytes and microglia—are closely linked to the progression of Alzheimer’s disease. One protein in particular, called AHNAK, was identified as a top driver of these harmful interactions.

 

About The Study: This cohort study of schools matched to child and adolescent patient medical records from a large network of community health organizations found that school participation in the Community Eligibility Provision was associated with a net reduction in blood pressure outcomes. These findings add to mounting evidence that universal free school meals may be associated with improved child health.

About The Study: The findings of this analysis suggest that the individualized treatment effect of low-dose aspirin on cancer prevention in older adults varies by participant characteristics. Further study is needed to fully understand the implications of these findings.
