Not too much here, but longevity research fans might like.
Time may be our worst enemy, and aging its most powerful weapon. Our hair turns gray, our strength wanes, and a slew of age-related diseases represent what is happening at the cellular and molecular levels. Aging affects all the cells in our body’s different tissues, and understanding its impact would be of great value in fighting this eternal enemy of all ephemeral life forms.
The key is to first observe and measure. In a paper published in Cell Reports, scientists led by Johan Auwerx at EPFL started by asking a simple question: how do the tissues of aging mice differ from those of mice that are mere adults?
To answer the question, the researchers used the multiple techniques to measure the expression of everyone one of the thousands of mouse’s genes, and to identify any underlying epigenetic differences. The researchers not only measured different layers of information, but they did it across three different tissues: liver, heart, and muscle.
