IUPUI study: Climate change drove population decline in New World before Europeans arrived

Researchers from IUPUI reconstructed 2,100 years of temperature and precipitation data, pointing to climate change as a primary cause of the disappearance of the Mississippians. The study found that drought conditions due to changed atmospheric circulation undermined agricultural production, leading to the destabilization of sociopolit...

Females no longer neglected in obesity research

A recent review in Frontiers in Nutrition highlights the need for a more inclusive approach to obesity research, as traditional male rat models are found to be insufficient in predicting long-term obesity in females. The study also sheds light on the phenomenon of weight regain after weight loss and its impact on females.
