We and other groups are seeing clear statistical links between telomere shortness and risk for a variety of diseases that are becoming very common, such as cardiovascular disease, diabetes and certain cancers.
Interpretation
Telomere length is linked to the risk of several common diseases.
Elizabeth Blackburn's quote emphasizes the scientific discovery that shorter telomeres, the protective caps on the ends of chromosomes, are statistically associated with an increased risk of various diseases, including cardiovascular disease, diabetes, and certain types of cancer. This connection highlights the importance of telomeres in health and disease, suggesting that they may serve as biomarkers for assessing disease risk and longevity.
In practice
In a lecture on genetics and health, one might open with Blackburn's quote to highlight the importance of telomeres.
Cancer cells have had so many other things go wrong with them, genetic, non-genetic changes, that those cells, one of the things they then get selected for is that they have lots of telomerase because now the telomeres in those cells get maintained.
Checking your telomere length is a bit like weighing yourself: you get this single number which depends on a lot of factors. Telomere length gives a sense of your underlying health.
We think there are lifestyle factors that boost telomerase naturally.
For me, arguably the story of telomeres and telomerase began thousands of years ago, in the cornfields of the Maya highlands of Central America.
If we think of our chromosomes - they carry our genetic material - as being like shoelaces, I work on the plastic tips at the end that protect them.
Being senior enough in the field, having enough solidity, I don't feel afraid of being marginalized.
Spacewalking trumps everything. Viscerally, it is a phenomenal place to be; to be able to glance right and see the world, glance left and see the universe, and realise for a moment that you're holding on to your known existence with one hand. That's the thing.
Science is nothing but developed perception, interpreted intent, common sense rounded out and minutely articulated.
If we had the fundamental laws of nature tomorrow, we still wouldn't understand consciousness. We wouldn't even understand turbulence.
Understanding vision and building visual systems is really understanding intelligence.
The human race has a yearning to explore. That's part of our biological and psychological makeup.
So, influenced by these advisors and this hope, I have at length allowed my friends to publish the work, as they had long besought me to do.
