The recently observed reduction in air pollution implies that more solar radiation reaches Earth’s surface. This could lead to a far more rapid increase in Earth’s temperature in the coming decades than has previously been expected. In order to successfully combat global warming, it is crucial that scientists incorporate increases in CO 2 emissions reductions as well as reductions in air …

Mice lacking a gene called TLR5 have an altered ability to recognize and control bacteria in their intestines, leading them to develop obesity and insulin resistance, which is often referred to as “pre-diabetes.” The bacteria appear to influence appetite and metabolism rather than how well calories are absorbed. Obesity and insulin resistance can be transferred from TLR5-deficient mice via …
