In a quiet Cambridge lab, scientists funded by the Wellcome Trust's £10 million have begun a quest to rival Mary Shelley's darkest dreams: creating human DNA from scratch. The Synthetic Human Genome Project, launched on June 26, 2025, promises to craft disease-resistant cells, repair organs, and unlock biology's secrets, as Dr. Julian Sale told BBC News. It's billed as a leap toward healthier lives, a sequel to the Human Genome Project that mapped our DNA 25 years ago. But like Dr. Frankenstein stitching together his creature, this project, noble in theory, courts catastrophe. From designer babies to biological weapons, the risks of unleashing synthetic DNA are as monstrous as they are real, and the safeguards feel like flimsy stitches holding back a nightmare.
The project's pitch is seductive: build DNA molecule by molecule, starting with the four building blocks (A, G, C, T), to create artificial chromosomes. These could reveal how genes govern our bodies, paving the way for treatments for incurable diseases. Prof. Matthew Hurles of the Wellcome Sanger Institute says synthetic DNA lets scientists "test out how DNA really works," unlike tweaking existing genes. Imagine a world where liver failure or heart disease is fixed with lab-grown, disease-proof cells. For a cancer patient in Manchester or a retiree in Birmingham, this sounds like salvation, a chance to live longer, healthier lives.
But Frankenstein, too, dreamed of conquering death. His creature was meant to be a triumph, not a terror. The Synthetic Human Genome Project's goals, confined to test tubes for now, assume a purity of purpose that history debunks. Science, unchecked, often becomes its own monster.
Critics like Dr. Pat Thomas of Beyond GM warn that this technology could be "repurposed to do harm and for warfare." Prof. Bill Earnshaw, a geneticist at Edinburgh University, is blunter: "The genie is out of the bottle." Once synthetic DNA tech exists, no law can stop an unscrupulous lab, be it in a rogue state or a corporate basement, from misusing it. The dangers are chilling:
Designer Babies: Synthetic chromosomes could let parents pick traits, blue eyes, high IQ, turning humans into custom orders. China's 2018 CRISPR twins sparked global outrage; this tech could make that look quaint.
Biological Weapons: A lab with "appropriate machinery," as Earnshaw notes, could craft DNA to unleash targeted pathogens. Imagine a virus engineered to attack specific ethnic groups, a fear raised by DARPA in 2023.
Corporate Control: Dr. Thomas asks, "Who owns synthetic body parts or people?" Healthcare giants like Pfizer, which spent $3.7 billion on ads in 2023, could patent synthetic DNA, turning your liver cells into their profit stream. Data from these creations, who controls it? Not you.
Unforeseen Mutations: Synthetic DNA, introduced into living systems, could trigger cascading errors. The Human Genome Project took 13 years to map DNA; we're nowhere near predicting how synthetic genes might misfire in future generations.
Victor Frankenstein's tragedy wasn't his ambition but his blindness to consequences. The Synthetic Human Genome Project mirrors this. Wellcome's Dr. Tom Collins admits the tech "is going to be developed one day," so they're funding it to "do it responsibly." But responsibility falters when the stakes are this high. The project's social science arm, led by Prof. Joy Zhang, promises public input, but can a sociologist's survey stop a biotech firm in Shenzhen or a Pentagon contractor from weaponising DNA? Frankenstein didn't consult the village before sparking life; these scientists, despite their ethics panels, may not either.
The Human Genome Project, funded by Wellcome, was a triumph of reading DNA. Writing it from scratch is a different beast. Frankenstein's creature turned on him because he ignored its humanity. Synthetic DNA, if mishandled, could turn on us all, through a lab leak, a corporate patent, or a dictator's whim.
Consider the human cost. A Liverpool family, hoping for a cure for their child's rare disease, might cheer this project. But what if their DNA becomes a corporate asset, or their child's synthetic genes cause unforeseen illnesses? A London nurse, trusting science to save lives, might not realize her genetic data could fuel a biotech arms race. The £4.7 billion UK spent on Covid vaccines taught us trust in science can be exploited when profit and power collide.
Wellcome's £10 million is a drop in the bucket, but it's a signal: the race is on. China, the US, and others won't wait for ethical debates. This is "the next giant leap in biology," but leaps into the unknown often end in falls. The BBC's coverage, framing it as a medical marvel, glosses over the risks, just as it hyped Covid vaccine claims without scrutiny. If the goal is healthier aging, why not fund safer bets, like improving NHS wait times or researching natural immunityEAD gene therapies? Instead, we're playing with fire.
The Synthetic Human Genome Project is Dr. Frankenstein in a lab coat, noble intent, catastrophic potential. Its promise of curing diseases is tantalising, but the risks, designer babies, bioweapons, corporate control, loom like Shelley's monster. Wellcome's "responsible" approach and public consultations feel like flimsy bolts on a Pandora's box.
This is the stuff of sci fi nightmares.

"Work has begun on a controversial project to create the building blocks of human life from scratch, in what is believed to be a world first.
The research has been taboo until now because of concerns it could lead to designer babies or unforeseen changes for future generations.
But now the World's largest medical charity, the Wellcome Trust, has given an initial £10m to start the project and says it has the potential to do more good than harm by accelerating treatments for many incurable diseases.
Dr Julian Sale, of the MRC Laboratory of Molecular Biology in Cambridge, who is part of the project, told BBC News the research was the next giant leap in biology.
"The sky is the limit. We are looking at therapies that will improve people's lives as they age, that will lead to healthier aging with less disease as they get older.
"We are looking to use this approach to generate disease-resistant cells we can use to repopulate damaged organs, for example in the liver and the heart, even the immune system," he said.
But critics fear the research opens the way for unscrupulous researchers seeking to create enhanced or modified humans.
Dr Pat Thomas, director of the campaign group Beyond GM, said: "We like to think that all scientists are there to do good, but the science can be repurposed to do harm and for warfare".
Details of the project were given to BBC News on the 25th anniversary of the completion of the Human Genome Project, which mapped the molecules in human DNA and was also largely funded by Wellcome.
Every cell in our body, with the exception of red blood cells, contains a molecule called DNA which carries the genetic information it needs.
DNA is built from just four much smaller blocks referred to as A, G, C and T, which are repeated over and over again in various combinations. Amazingly it contains all the genetic information that physically makes us who we are.
The Human Genome Project enabled scientists to read all human genes like a bar code. The new work that is getting under way, called the Synthetic Human Genome Project, potentially takes this a giant leap forward – it will allow researchers not just to read a molecule of DNA, but to create parts of it – maybe one day all of it - molecule by molecule from scratch.
Scientists will begin developing tools to create ever larger sections of human DNA
The scientists' first aim is to develop ways of building ever larger blocks of human DNA, up to the point when they have synthetically constructed a human chromosome. These contain the genes that govern our development, repair and maintenance.
These can then be studied and experimented on to learn more about how genes and DNA regulate our bodies.
Many diseases occur when these genes go wrong so the studies could lead to better treatments, according to Prof Matthew Hurles, director of the Wellcome Sanger Insititute which sequenced the largest proportion of the Human Genome.
"Building DNA from scratch allows us to test out how DNA really works and test out new theories, because currently we can only really do that by tweaking DNA in DNA that already exists in living systems".
Machines at the Sanger Institute were used to sequence the human genome
The project's work will be confined to test tubes and dishes and there will be no attempt to create synthetic life. But the technology will give researchers unprecedented control over human living systems.
And although the project is hunting for medical benefits, there is nothing to stop unscrupulous scientists misusing the technology.
They could, for example, attempt to create biological weapons, enhanced humans or even creatures that have human DNA, according to Prof Bill Earnshaw, a highly respected genetic scientist at Edinburgh University who designed a method for creating artificial human chromosomes.
"The genie is out of the bottle," he told BBC News. "We could have a set of restrictions now, but if an organisation who has access to appropriate machinery decided to start synthesising anything, I don't think we could stop them"
Ms Thomas is concerned about how the technology will be commercialised by healthcare companies developing treatments emerging from the research.
"If we manage to create synthetic body parts or even synthetic people, then who owns them. And who owns the data from these creations? "
Given the potential misuse of the technology, the question for Wellcome is why they chose to fund it. The decision was not made lightly, according to Dr Tom Collins, who gave the funding go-ahead.
"We asked ourselves what was the cost of inaction," he told BBC News.
"This technology is going to be developed one day, so by doing it now we are at least trying to do it in as responsible a way as possible and to confront the ethical and moral questions in as upfront way as possible".
A dedicated social science programme will run in tandem with the project's scientific development and will be led by Prof Joy Zhang, a sociologist, at the University of Kent.
"We want to get the views of experts, social scientists and especially the public about how they relate to the technology and how it can be beneficial to them and importantly what questions and concerns they have," she said."
