Man-on-a-chip

Among the "organs on chips" there are hearts that beat, and lungs that breathe, as well as the liver, fallopian tubes, etc. Now scientists are thinking about how to combine these organs into a single "organism-on-chips".

Your age will be determined by epigenetics

The analysis of epigenetic modification of genes in cells that can be obtained from a saliva sample allows us to determine the age of a person with an accuracy of 5 years. In the future, it can be used to determine the biological age.
