"If you don't understand how DNA works, you're at a huge disadvantage in this century."
This quote underscores the importance of understanding DNA (Deoxyribonucleic Acid) in the 21st century, as it is the blueprint for all life. Genetic information encoded in DNA determines the traits of organisms, and manipulating this genetic material is at the core of many modern scientific breakthroughs, including advances in medicine, agriculture, and biotechnology. Therefore, ignorance about DNA could potentially limit one's ability to fully participate or excel in these fields, as well as hinder progress in understanding the fundamental underpinnings of life itself.
"Synthetic biology is not just the future; it's here now."
This quote by George M. Church implies that Synthetic Biology, a field which involves designing and constructing new biological parts, devices, and systems or redesigning existing ones to increase functionality, efficiency, or to perform new functions, is no longer limited to the realm of future possibilities. It suggests that advancements in this area have reached a stage where its practical applications are already present and evident in today's world.
"Science isn't always right, but it's a self-correcting process that eventually gets there."
This quote emphasizes the iterative and evolving nature of scientific inquiry, where findings are not absolute truths but rather tentative hypotheses subject to continuous evaluation and refinement. The "self-correcting" aspect implies that errors or inconsistencies in the understanding of a phenomenon will eventually be identified and addressed through further observation, experimentation, and collaboration within the scientific community. Ultimately, this process aims to lead to increasingly accurate and reliable knowledge about the world.
"I think we should be trying to make our own species better, in a way that's thoughtful and responsible."
This quote from George M. Church emphasizes the importance of continuous improvement and evolution as a species, guided by careful thought and responsibility. It suggests that humanity should strive for progress not just for progress' sake, but with an understanding of the potential consequences and in a manner that upholds ethical standards. In other words, it advocates for a proactive approach to human advancement that prioritizes sustainable development and moral consideration.
"We can engineer biology now, in ways that have never been possible before."
This quote by George M. Church emphasizes the recent advancements in biotechnology, suggesting we now possess the ability to modify biological systems in a manner hitherto unachievable. It underscores the power of modern science to manipulate life at its most fundamental levels, opening up possibilities for significant breakthroughs in areas like medicine, agriculture, and environmental conservation.
What dinosaur traits are missing from an ostrich? The ostrich has a toothless beak, but there are mutations that cause teeth and claws to come back to their mouth and limbs. You need to replace the feathers with scales, but there are no feathers on their legs and feet, so you just need to make its whole body like its legs are.
- George M. Church
Clearly, we are a species that is well connected to other species. Whether or not we evolve from them, we are certainly very closely related to them. A series of mutations could change us into all kinds of intermediate species. Whether or not those intermediate species are provably in the past, they could easily be in our future.
- George M. Church
We have the ability to completely change our environment to go... to take on... to inherit, in a certain sense, things far beyond our DNA, and that's inheritable. And we can see evolution in action as our ideas evolve and undergo a kind of Darwinian selection not at the DNA level. And we can go off into space.
- George M. Church
If you get a personal genome, you should be able to get personal cell lines, stem cell derived from your adult tissues, that allow you to bring together synthetic biology and the sequencing so that you can repair parts of your body as you age or repair things that were inherited disorders.
- George M. Church
Most people are excited about themselves. Personal genome will deliver for inexpensively something about science to which you can relate. Just like computers are becoming something to which you can relate. It should be even easier to relate to your own biology, and I hope that will be one of the ways we get broader literacy in science.
- George M. Church
Every cell in our body, whether it's a bacterial cell or a human cell, has a genome. You can extract that genome - it's kind of like a linear tape - and you can read it by a variety of methods. Similarly, like a string of letters that you can read, you can also change it. You can write, you can edit it, and then you can put it back in the cell.
- George M. Church
A few dozen changes to the genome of a modern elephant - to give it subcutaneous fat, woolly hair and sebaceous glands - might suffice to create a variation that is functionally similar to the mammoth. Returning this keystone species to the tundras could stave off some effects of warming.
- George M. Church
Reversal is something that has been demonstrated in a number of different animals in a number of different ways. I think that's going to translate into larger animals and humans. We won't know until we try. But we are trying 65 different genes in different combinations to see if we can reproduce the aging reversal that we've seen in small animals.
- George M. Church
We will have to make a decision, as we go into new environments outside of earth, whether we want to drag along with us all our pathogens. We can, or we can't - it's up to us - but I consider that part of genome engineering is how we interact with the huge part of our genome which is our microbiome.
- George M. Church
