Research sheds new light on how the microbiome is involved in obesity

Scientists have discovered that specific molecules produced by intestinal bacteria are altered during three instances associated with human obesity. The study also found that the gut microbiome undergoes fluctuations in a 24-hour rhythm and influences circadian biology, predisposing individuals to obesity and glucose intolerance.

Human ancestors not to blame for ancient mammal extinctions in Africa

A study by University of Utah researchers suggests that grassland expansion, driven by falling atmospheric carbon dioxide levels, drove the decline of giant mammals over the last 4.6 million years. The research provides a convincing counter-argument to long-held views on human ancestors' impact on ancient African faunas.
