Scientists uncover why the human heart can't regenerate itself
Stem cell researchers at UCLA have uncovered for the first time why adult human cardiac myocytes have lost their ability to proliferate, perhaps explaining why the human heart has little regenerative capacity.

More than 3,000 epigenetic switches control daily liver cycles
(Medical Xpress)—When it's dark, and we start to fall asleep, most of us think we're tired because our bodies need rest. Yet circadian rhythms affect our bodies not just on a global scale, but at the level ...

Weakness in aging tied to leaky muscles
There is a reason exercise becomes more difficult with age. A report in the August Cell Metabolism, a Cell Press publication, ties the weakness of aging to leaky calcium channels inside muscle cells. But there is some good n ...

Tortoise and the hare: New drug stops rushing cancer cells, slow and steady healthy cells unharmed
The American Cancer Society estimates that 44,000 new cases of pancreatic cancer will be diagnosed this year and that 37,000 people will die from the disease. These are not strong odds. A new drug, rigosertib, allows pancreatic ...

Molecular switch identified that controls key cellular process
The body has a built-in system known as autophagy, or 'self-eating,' that controls how cells live or die. Deregulation of autophagy is linked to the development of human diseases, including neural degeneration and cancer.
