Senescence or biological aging is the change in the biology of an organism as it ages after its maturity. Such changes range from those affecting its cells and their function to those affecting the whole organism. There are a number of theories as to why senescence occurs; for example, some posit it is programmed by gene expression changes, others that it is the cumulative damage caused by biological processes. Senescence is not the inevitable fate of all organisms. A variety of organisms, including some cold-blooded animals, have negligible senescence. Whether senescence as a biological process can be slowed down, halted or even reversed, is a subject of current scientific speculation and research.
The word senescence is derived from the Latin word senex, meaning old man, old age, or advanced in age.

Validating maps of the brain's resting state
Kick back and shut your eyes. Now stop thinking. You have just put your brain into what neuroscientists call its resting state. What the brain is doing when an individual is not focused on the outside world ...
Scientists create way to see structures that store memories in living brain
Oscar Wilde called memory "the diary that we all carry about with us." Now a team of scientists has developed a way to see where and how that diary is written.
A new understanding of the genetic process that can lead to cervical cancer may help improve diagnosis of potentially dangerous lesions for some women, and also raises a warning flag about the use of anti-viral therapies ...
