Tooth study prompts rethink of human evolution

A recent study of wild Japanese macaques has found atypical tooth wear patterns that challenge our understanding of human evolution. The research suggests that the 'toothpick' grooves and large uniform scratches observed in fossil humans may have been caused by eating shellfish and accidentally chewing grit and sand, rather than tool use.

CHOP researchers show early developmental delays predict poor long-term outcomes in Leigh syndrome patients

Researchers from the Mitochondrial Medicine Frontier Program at CHOP found that primary developmental delays are a common symptom of Leigh syndrome, occurring even before metabolic stroke and regression. These delays are associated with poor long-term educational outcomes and worse disease progression.

Decreasing carbon sink across the Belt and Road in the future

Climate change, elevated CO2 concentrations, and increasing nitrogen fixation are projected to reduce the Belt and Road region's net ecosystem production trend by ~40% from 2031-2100. Net primary production may increase in response to rising CO2, but soil respiration is expected to rise more, leading to a decrease in carbon sequestration.
