00:00Good day, esteemed listeners.
00:22Today, we embark on an intellectual journey into one of the most transformative and,
00:28at the same time, most troubling areas of human knowledge the world of genetic engineering.
00:34This is not just a set of biotechnological methods, it is a fundamental paradigm shift
00:39in our interaction with the very basis of life the genetic code.
00:43Genetic engineering represents a synthesis of the highest achievements of genetics, molecular
00:48biology, bioinformatics, and virology, aimed at the targeted, precise alteration of the
00:54hereditary traits of living organisms through direct intervention in the structures of DNA
00:59and RNA.
01:01Its potential benefits are as grand as they are biblical, from victory over hereditary
01:05diseases that have plagued humanity for centuries to the creation of agricultural systems capable
01:11of feeding the planet's growing population in the face of climate collapse.
01:15However, as in the story of the tree of knowledge, along with limitless possibilities, we also
01:21receive colossal responsibility and the most serious ethical dilemmas, challenging our traditional
01:27notions of naturalness, justice, human nature, and the very future of our species.
01:33These questions cannot remain within laboratory walls, they require the broadest public discussion,
01:39deep philosophical understanding, and robust legal regulation.
01:43To understand the scale of the modern revolution, it is necessary to turn to its origins.
01:49The foundation was laid in the 19th century by the work of Gregor Mendel, who, by studying
01:55the inheritance of traits in peas, empirically discovered the basic laws of genetics.
02:00However, the real revolution occurred a century later, in 1972, when a group of visionary scientists
02:08Paul Berg, Stanley Cohen, and Herbert Boyer achieved the impossible, they created the world's
02:13first recombinant DNA.
02:16This was a molecule stitched together from fragments of DNA from different organisms a
02:20virus and a bacterium E. coli.
02:23This work not only marked the beginning of genetic engineering as such but also sparked the first
02:28wave of ethical anxieties, forcing the scientists themselves to voluntarily impose a moratorium on
02:33certain types of experiments until safety measures were developed.
02:38Since then, technologies have developed exponentially.
02:41DNA sequencing methods, PCR, and RNA interference emerged.
02:47But the truly stellar moment arrived with the discovery and adaptation of the CRISPR-C9 system.
02:54This system, originally an immune mechanism of bacteria for protection against viruses, was adapted
03:00into a universal tool for gene editing.
03:03Its creators, Jennifer Doudna and Emmanuel Charpentier, essentially gave scientists molecular scissors
03:09with incredibly high precision and programmability.
03:13CRISPR-C9 allows for finding a specific section in a genome consisting of billions of letters and
03:18making changes to it cutting, inserting, replacing.
03:23Even today, we see staggering results from this technology.
03:27A prime example is the treatment of severe combined immunodeficiency, SCIDX1, known as bubble boy syndrome.
03:36At a children's hospital in Memphis, a group of children with this lethal genetic mutation
03:41had their own hematopoietic cells taken.
03:44Using CRISPR, the error in the gene responsible for the disease was corrected in vitro.
03:50These edited, healthy cells were then returned to the patient's bodies, where they engrafted and
03:55began producing functional immune cells.
03:59Children doomed to life in sterile boxes can now go to school, play with peers, and live
04:04full lives.
04:05This is not science fiction, it is today's reality, demonstrating the life-saving medical
04:11potential of genetic engineering.
04:13The potential of genetic engineering extends far beyond hospitals.
04:18One of its first and most controversial applications became agriculture and the creation of genetically
04:23modified organisms .
04:27Critics often paint apocalyptic pictures, but the reality is much more pragmatic and is
04:32already bearing fruit.
04:34We are talking about solving global problems.
04:37Increasing yield and resilience, scientists have created crops resistant to insect pests,
04:43for example corn and cotton producing the bacillus thuringiensis protein, safe for humans but
04:48lethal to specific pests, to herbicides, allowing for more effective weed control, and to drought
04:55and soil salinity.
04:57This is a direct response to the threat to food security under climate change.
05:02Improving nutritional value, a prime example is golden rice, enriched with beta-carotene,
05:08a precursor to vitamin A.
05:10Vitamin A deficiency is a cause of blindness and the death of hundreds of thousands of
05:14children annually in developing countries.
05:18Genetic engineering offers not just food, but nutritional medicine.
05:23Ecological potential, work is underway to create phytomediator plants capable of extracting
05:28and accumulating heavy metals, lead, mercury, cadmium, and other toxic compounds from the soil,
05:35thereby cleansing contaminated industrial zones.
05:39Genetic fields that not only yield a harvest but also heal the land.
05:43However, serious questions also arise here.
05:47Will the spread of herbicide-resistant crops lead to excessive use of chemicals?
05:53Will pests develop resistance to built-in insecticides?
05:56The greatest ecological threat is the possibility of gene leakage, cross-pollination of modified crops
06:02with their wild relatives could lead to unpredictable and irreversible changes in natural ecosystems, disrupting the fragile balance of biodiversity.
06:11If the editing of somatic cells, as in the case of SCID therapy, affects only one patient and is not inherited, then intervention in the germline is a qualitatively different level.
06:22Editing the DNA of sperm, eggs, or embryos at an early stage of development means that all changes will be inherited by all subsequent generations.
06:33Theoretically, this is humanity's greatest chance to eradicate monogenic hereditary diseases forever, Huntington's chorea, cystic fibrosis, sickle cell anemia, thalassemia.
06:46We could eliminate the very cause of suffering by cutting the defective gene out of a family's gene pool forever.
06:51But this is precisely where we open the proverbial Pandora's box.
06:56After all, the same tool that corrects a disease-causing mutation could theoretically be used for enhancement human improvement.
07:04This refers to attempts to insert genes associated with increased cognitive abilities, photographic memory, perfect pitch, ideal physical build, or even certain character traits.
07:17This gives rise to the nightmare scenario of designer children and a new form of eugenics not state-sponsored and coercive, as in the last century, but commercial and voluntary.
07:27A fundamental threat to social equality arises.
07:31Gene editing technologies are extremely expensive today.
07:35What if they become a luxury available only to the top 1% of the population?
07:40They risk creating a genetic divide in society, a cast of natural people and a cast of genetically enhanced individuals healthier, smarter, more beautiful, and longer living.
07:51This could lead to unprecedented forms of discrimination at the genetic level, as warned by Marcy Darnovsky from the Center for Genetics and Society.
08:00Equality of opportunity, a cornerstone of modern democracies, would be destroyed in its infancy, literally at the DNA level.
08:09Ethical debates are not limited to utilitarian questions of benefit and harm.
08:14They are rooted in deep philosophical and religious layers.
08:18Many religious denominations see in genetic engineering, especially concerning humans, an act of disobedience and pride playing God.
08:26If life and its forms are divine creations, then any attempt to radically change them represents a violation of the sacred order and providence.
08:35The Christian Church Union in its 2003 statement directly condemned manipulations aimed at gender selection or other forms of social engineering, calling for their ban.
08:46Similar views are common in other Abrahamic religions, as well as in many movements of Hinduism and Buddhism, where the concept of natural balance and karma plays an important role.
08:57From a secular, philosophical perspective, genetic engineering calls into question the very concept of human identity and autonomy.
09:06French existentialist Jean-Paul Sartre argued that man is condemned to be free he is defined not by his essence but by his actions and choices.
09:14But what happens when a person's fundamental characteristics their health, potential, even temperament are predetermined by an engineer in a laboratory before birth, without their consent?
09:25Are we depriving the future person of their right to self-determination, to their own, perhaps difficult, but unique destiny?
09:33Is the line between given and made being erased?
09:37Are we turning a human from a subject into an object, a product of their parents' design project?
09:43One of the most acute practical problems is the almost complete absence of consistent and universally accepted international regulation.
09:51The legal landscape is a patchwork of national laws, ranging from complete bans to relatively liberal approaches.
09:58For example, in the UK, under strict regulation, editing of human embryos for research purposes is permitted, but with a strict limitation embryos cannot develop beyond 14 days and cannot be implanted in the uterus for further gestation.
10:14This is an ethical compromise that allows for the study of early development and the causes of miscarriages.
10:20In contrast, there was the loud scandal of Chinese scientist He Jiankui, who in 2018 bypassed all national and international norms to conduct an illegal experiment editing embryos to give them resistance to HIV.
10:34As a result, the world's first genetically modified twin girls were born.
10:39This case caused shock and unanimous condemnation from the global scientific community, demonstrating the vulnerability of the system and the catastrophic consequences of the actions of lone wolves.
10:51This incident highlighted the urgent need to develop global standards and create international oversight bodies, similar to the IAEA but in the field of bioethics.
11:01Such regulations should be based on several key principles.
11:05The precautionary principle, the need to act with extreme caution in the absence of a full understanding of all long-term consequences.
11:13The principle of justice, guaranteeing that the benefits of genetic engineering will be distributed evenly and not become a privilege of the rich.
11:21The principle of informed consent, fully and clearly informing patients and research participants of all potential risks and benefits.
11:30The principle of transparency, openness of scientific research to public scrutiny and discussion.
11:37Beyond medical and agricultural applications, there is also a dark but inevitable aspect the potential for misuse of the technologies.
11:45Already today, underground biohackers are offering dubious genetic procedures bypassing any regulations.
11:52The democratization of technology and the reduction of its cost lead to the risk of its use by irresponsible amateurs with unpredictable consequences.
12:01But the most serious threat is the militarization of genetic engineering.
12:05One can imagine scenarios of creating targeted biological agents capable of affecting specific ethnic groups with a unique genetic profile.
12:14Or projects to enhance soldiers, increasing muscle mass, pain tolerance, reduced need for sleep, visual acuity creating the perfect biological soldier.
12:25Such developments, if they are underway, raise monstrous ethical and political questions that could undermine the very foundation of international security and blur the boundaries of warfare.
12:36Despite all the risks, scientific thought continues to move forward.
12:41CRISPR-CAN9 is not the end point but merely the beginning.
12:45New, even more precise tools are already being developed and refined.
12:50Base editing, which allows changing individual DNA letters without breaking the chain.
12:55And prime editing, which is claimed to be capable of performing any type of editing with minimal errors.
13:01Alternative systems based on TALEN and ZFN proteins are emerging.
13:06In medicine, CAR-T cell cancer therapy is gaining momentum, where a patient's T lymphocytes are genetically modified to better recognize and destroy tumor cells.
13:16The successful treatment of leukemia in a child at London's Great Ormond Street Hospital using TALEN is just one example.
13:23Work continues on fighting HIV through the deletion or editing of the CCR5 receptor gene, as in the case of patient Matt Chappell, who lives without therapy.
13:33In agriculture, the future promises the emergence of smart crops that are not only stress resistant but also capable of independently producing more vitamins or even signaling a lack of water by changing color.
13:46In animal husbandry, work is underway to create breeds resistant to epidemics, example African swine fever or bovine leukemia virus, which could save entire farms from bankruptcy.
13:58But this bright scenario can only be realized through continuous and inclusive public dialogue.
14:05Scientists cannot and should not make these decisions alone.
14:09Society needs education and enlightenment so that ordinary people without scientific degrees can understand the basics and participate in the discussion about their future.
14:18Scientists, in turn, must adhere to the highest ethical standards and be as transparent as possible.
14:25Jennifer Doudna's admission of having nightmares in which a figure like Hitler shows interest in her technology is a powerful warning to the entire community about the duality of any great discovery.
14:36In conclusion, genetic engineering is not just a tool, it is a powerful force capable of restructuring the very fabric of life on earth.
14:46It offers us a dream of a world without suffering, hunger, and many diseases.
14:51But it also carries the seeds of a potential nightmare, a world of deepened inequality, genetic discrimination, and unpredictable environmental disasters.
15:01The ethical boundaries of this science are not given once and for all, they reflect our collective values, the pursuit of justice, respect for human dignity, care for the fragile balance of nature, and responsibility to future generations.
15:16As a society, we face an incredibly difficult collective task to find a wise and balanced equilibrium between unbridled technological optimism and conservative fear of the new.
15:26We must jointly determine where that red line lies that separates healing from enhancement, aiding evolution from violently interrupting it, using power from playing with fire.
15:37Only through open, honest, and global dialogue can we direct the colossal potential of genetic engineering to serve humanity without losing our very human essence in the process.
15:47Thank you for your attention.
