Early childhood deprivation is associated with alterations in adult brain structure despite subsequent environmental enrichment [Neuroscience]
Early childhood deprivation is associated with higher rates of neurodevelopmental and mental disorders in adulthood. The impact of childhood deprivation on the adult brain and the extent to which structural changes underpin these effects are currently unknown. To investigate these questions, we utilized MRI data collected from young adults who…

Four ways to reduce the carbon in your food basket
How does your food shop affect the planet? Well, think of it like this—consuming just one egg emits between 260 and 330g of CO₂ to the atmosphere.

That hen then needs heating pumped into the shed it shares with the other hens on the farm, and their eggs have to be transported,
