Fission Yeast Does Not Age under Favorable Conditions, but Does So after Stress
BACKGROUND Many unicellular organisms age: as time passes, they divide more slowly and ultimately die. In budding yeast, asymmetric segregation of cellular damage results in aging mother cells and rejuvenated daughters. We hypothesize that the organisms in which this asymmetry is lacking, or can be modulated, may not undergo aging. RESULTS We performed a complete pedigree analysis of microcol...
متن کاملWhy does the central nervous system not regenerate after injury?
A major problem for neuroscientists and clinicians is why the central nervous system shows ineffective regeneration after injury. Injured peripheral nerve fibers reform their connections, whereas those in injured spinal cord never re-grow. Insights into the mechanisms for repair and restoration of function after spinal cord injury have been obtained by experiments showing that injured nerve cel...

متن کاملReality Does Not Recognize Borders
Reality does not recognize borders. Why we should use the very general term of “reality” and not science, because the borders that we draw are pure delusions, and on the opposite side there is the reality. The laws of the universe, either the physical nature of the world which the scientist studies or metaphysics which is the territory of philosophers, it isthe same reality that rules. Today ma...
متن کاملTelomerase does not counteract telomere shortening but protects mitochondrial function under oxidative stress.
Telomerase is a ribonucleoprotein that counteracts telomere shortening and can immortalise human cells. There is also evidence for a telomere-independent survival function of telomerase. However, its mechanism is not understood. We show here that TERT, the catalytic subunit of human telomerase, protects human fibroblasts against oxidative stress. While TERT maintains telomere length under stand...
