The Anthropocene's human‐dominated habitat expansion endangers global biodiversity. However, large mammalian herbivores experienced few extinctions during the 20th century, hinting at potentially overlooked ecological responses of a group sensitive to global change. Using dental microwear as a proxy, we studied large herbivore dietary niches over a century across mainland China before (1880s–1910s) and after (1970s–1990s) the...

The blood–brain barrier (BBB) undergoes functional changes with aging which may contribute to cognitive decline. A novel, diffusion prepared arterial spin labeling-based MRI technique can measure the rate of water exchange across the BBB ( k w ) and may thus be sensitive to age-related alterations in water exchange at the BBB. However, studies investigating relationships between k w and cognition have reported different direct...
