Fundamentals of Synthetic Biology
REDESIGNING LIFE

THE PROMISE AND PERILS OF SYNTHETIC BIOLOGY

For the past four billion years or so the only way for life on Earth to produce a sequence of DNA—a gene—was by copying a sequence it already had to hand. Sometimes the gene would be damaged or scrambled(xáo trộn), the copying imperfect or undertaken repeatedly. From that raw material arose the glories of natural selection. But beneath it all, gene begat(sinh ra) gene.
That is no longer true. Now genes can be written from scratch and edited repeatedly, like text in a word processor. The ability to engineer living things which this provides represents a fundamental change in the way humans interact with the planet’s life. It permits the manufacture of all manner of things which used to be hard, even impossible, to make: pharmaceuticals(dược phẩm), fuels, fabrics, foods and fragrances(nước hoa) can all be built molecule(phân tử) by molecule. What cells do and what they can become is engineerable, too. Immune cells(tế bào miễn dịch) can be told to follow doctors’ orders; stem cells(tế bào gốc) better coaxed to turn into new tissues(mô); fertilised eggs programmed to grow into creatures quite unlike their parents.
The earliest stages of such “synthetic biology(sinh học tổng hợp)” are already changing many industrial processes, transforming medicine and beginning to reach into the consumer world (see Technology Quarterly). Progress may be slow, but with the help of new tools and a big dollop of machine learning, biological manufacturing could eventually yield truly cornucopian technologies. Buildings may be grown from synthetic wood or coral. Mammoths(voi ma mút) produced from engineered elephant cells may yet stride across Siberia.
The scale of the potential changes seems hard to imagine. But look back through history, and humanity’s relations with the living world have seen three great transformations: the exploitation of fossil fuels, the globalisation of the world’s ecosystems after the European conquest of the Americas, and the domestication of crops and animals at the dawn of agriculture. All brought prosperity(sự thành công) and progress, but with damaging side-effects. Synthetic biology promises similar transformation. To harness(khai thác) the promise and minimise the peril, it pays to learn the lessons of the past.
The new biology calls all in doubt
Start with the most recent of these previous shifts. Fossil fuels have enabled humans to drive remarkable economic expansion in the present using biological productivity from ages past, stored away in coal and oil. But much wilderness has been lost, and carbon atoms(nguyên tử) which last saw the atmosphere hundreds of millions of years ago have strengthened the planet’s greenhouse effect to a degree that may prove catastrophic (thảm khốc). Here, synthetic biology can do good. It is already being used to replace some products made from petrochemicals; in time it could replace some fuels, too. This week Burger King introduced into some of its restaurants a beefless Whopper that gets its meatiness from an engineered plant protein; such innovations could greatly ease a shift to less environmentally taxing(đòi hỏi cố gắng) diets. They could also be used to do more with less. Plants and their soil microbes(vi sinh vật) could produce their own fertilisers and pesticides, ruminants less greenhouse gas—though to ensure that synthetic biology yields such laudable environmental goals will take public policy as well as the cues of the market.
The second example of biological change sweeping the world is the Columbian exchange, in which the 16th century’s newly global network of trade shuffled together the creatures of the New World and the Old. Horses, cattle and cotton were introduced to the Americas; maize, potatoes, chilli and tobacco to Europe, Africa and Asia. The ecosystems in which humans live became globalised as never before, providing more productive agriculture all round, richer diets for many. But there were also disastrous consequences. Measles(bệnh sởi), smallpox and other pathogens ran through the New World like a forest fire, claiming tens of millions of lives. The Europeans weaponised this catastrophe (thảm họa), conquering lands depleted and disordered by disease.
Synthetic biology could create such weapons by design: pathogens designed to weaken, to incapacitate or to kill, and perhaps also to limit themselves to particular types of target. There is real cause for concern here—but not for immediate alarm. For such weaponisation would, like the rest of cutting-edge synthetic biology, take highly skilled teams with significant resources. And armies already have lots of ways to flatten(san bằng) cities and kill people in large numbers. When it comes to mass destruction, a disease is a poor substitute for a nuke(vũ khí hạt nhân). What’s more, today’s synthetic-biology community lives up to ideals of openness and public service better than many older fields. Maintained and nurtured, that culture should serve as a powerful immune system against rogue(bất hảo) elements.
The earliest biological transformation—domestication—produced what was hitherto(cho đến nay) the biggest change in how humans lived their lives. Haphazardly, then purposefully, humans bred cereals to be more bountiful, livestock to be more docile, dogs more obedient and cats more companionable (the last a partial success, at best). This allowed new densities of settlement and new forms of social organisation: the market, the city, the state. Humans domesticated themselves as well as their crops and animals, creating space for the drudgery of subsistence agriculture(nông nghiệp tự cung tự cấp) and oppressive political hierarchies(hệ thống phân cấp).
Synthetic biology will have a similar cascading effect, transforming humans’ relationships with each other and, potentially, their own biological nature(bản chất). The ability to reprogram the embryo is, rightly, the site of most of today’s ethical concerns. In future, they may extend further; what should one make of people with the upper-body strength of gorillas, or minds impervious to sorrow? How humans may choose to change themselves biologically is hard to say; that some choices will be controversial is not.
Which leads to the main way in which this transformation differs from the three that came before. Their significance was discovered only in retrospect(trong hồi tưởng). This time, there will be foresight. It will not be perfect: there will certainly be unanticipated effects. But synthetic biology will be driven by the pursuit of goals, both anticipated and desired. It will challenge the human capacity for wisdom and foresight. It might defeat it. But carefully nurtured, it might also help expand it.
