Scientists Drove Mice to Bond by Zapping Their Brains With Light
The study, a tour de force in bioengineering, comes after two decades of research on brain-to-brain synchrony in people.

Late one evening last March, just before the coronavirus pandemic shut down the country, Mingzheng Wu, a graduate student at Northwestern University, plopped two male mice into a cage and watched as they explored their modest new digs: sniffing, digging, fighting a little.

Stem Cells and Bodybuilding For Muscle Building and Regeneration Stem Cells and Bodybuilding For Muscle Building and Regeneration Written by TEAM MD
Muscle regeneration is dependent on muscle progenitor cells (MPCs), which can be activated by certain nutrients and growth factors such as insulin-like growth factor 1 (IGF-1). IGF-1 can increase protein synthesis. The ability of nutrition and dietary intervention to stimulate IGF-1 and other growth factors is an exciting area of research, and has the potential to restore and enhance muscle regeneration and muscle growth.
IGF-1 increases muscle hypertrophy, muscle mass and strength, and reduces muscle degeneration by increasing satellite cells. Satellite cells are also known as adult muscle stem cells. They promote muscle growth and repair upon injury. Human studies have shown that resistance training exercise and certain nutrients and growth factors can boost
