 | Researchers at Mayo Clinic have discovered that senescent cells — cells that no longer divide and accumulate with age — shorten lifespan by as much as 35 percent in normal mice. Removing these aging cells delays tumor formation, preserves tissue and organ function, and extends lifespan without observed adverse effects, the researchers found, writing Feb. 3 in Nature. … more… |

How to rejuvenate or prevent aging in human and mice cells
An international team of scientists led by João Passos at Newcastle University has for the first time shown that mitochondria (the “batteries” of the cells) are major triggers for aging, and eliminating them upon the induction of senescence prevents senescence in the aging mouse liver. As we grow old, cells in our bodies accumulate different types … more… |

Could also help researchers map the brain
Caltech biologists have modified a harmless virus to allow it to enter the adult mouse brain through the bloodstream and deliver genes to cells of the nervous system. The modified virus could lead to novel therapeutics to address diseases such as Alzheimer’s and Huntington’s, help researchers map the brain, and target cells in other organs, according … more… |
