Primary Cilia in Neurons Linked to Obesity
Abby Olena | Jan 8, 2018
Three studies—one of mice and two of human genetics—describe the role of two proteins, adenylyl cyclase and melanocortin 4 receptor, in the development of obesity and diabetes.
All Native Americans Descended from One Ancestral Population
Abby Olena | Jan 3, 2018
The genome of an infant who lived in Alaska thousands of years ago represents a previously unknown group of humans called Ancient Beringians, who share a common lineage with other Native Americans.
