Mitochondria Drive Cell Survival in Times of Need

The research, published in Molecular Cell, builds on previous work by McGill professor Nahum Sonenberg, one of the senior authors of the new study. Cells in our body grow in size, mass and numbers through a process governed by a master regulator known as mTOR (Mechanistic Target of Rapamycin). Sonenberg discovered years

Human Skin Cells Transformed Directly Into Motor Neurons

In new research, scientists at Washington University School of Medicine in St. Louis have converted skin cells from healthy adults directly into motor neurons without going through a stem cell state. The technique makes it possible to study motor neurons of the human central nervous system in the lab. Unlike commonly

Brain Cells Found to Control Aging

The hypothalamus was known to regulate important processes including growth, development, reproduction and metabolism. In a 2013 Nature paper, Einstein researchers made the surprising finding that the hypothalamus also regulates aging throughout the body. Now, the scientists have pinpointed the cells in the hypothalamus that control aging: a tiny population of adult

Possible Treatment for Deadly Weight Loss

Doctors have known about this serious complication affecting cancer patients for a long time. The ancient Greeks called it cachexia, meaning "bad condition." Many cancer patients develop cachexia. An estimated 20 to 30 per cent of those with the condition may die of it and not from their tumors. For many of
