Mutations in the presenilin gene, PSEN1, causes early onset of Alzheimer’s disease in humans and in fruit flies modified to have this gene. A new study led by researchers at Penn State revels that disrupting heparan sulfate–modified proteins in fruit flies suppressed neuronal death and corrected other cell deficits common in early stages of Alzheimer’s and other neurodegenerative diseases. Pictured here are full fruit fly brains, stained with a marker that indicates cell death—brighter colors indicate higher presence of cell death. Top: A fly with deficits in the presenilin gene—a model for Alzheimer’s disease—with high levels of cell death. Bottom: A fly rescued by disrupting heparan sulfate–modified proteins.

In a blind taste test, recently published in the Journal of Food Science, 25% reduced-sugar chocolates made with oat flour were rated equally, and in some cases preferred, to regular chocolate.
