007skaty Each cell division shortens telomeres until replication stops, but Elizabeth Blackburn discovered that the enzyme telomerase can rebuild them.
007skaty Yamanaka Factors
Reset the clock, reset the clock, four proteins turn the cell back.

007skaty Clearing these senescent cells prevents tissue decay and delays age-related diseases.

BETA
007skaty Adjust the freezing temperature to learn how cryonics preserves cells for the future.
Fun Fact
Cold survival: In 1967, psychology professor James Bedford became the first person cryonically preserved, and he remains frozen today.
Glossary
telomerase (noun)
An enzyme that preserves the length of telomeres by adding repetitive DNA sequences to chromosome ends. In 1984, Elizabeth Blackburn co-discovered this enzyme, which helps researchers study ways to delay human cellular aging.
