By Bernard Marr

Steve Jobs once said that the biggest innovations in the 21st century would be at the intersection of biology and technology. As with all areas of technology, the global pandemic has accelerated both the development and adoption of biotech, with the hope that it will lead to new solutions for major global challenges, including illness, food shortages,and damage to the environment.

Here’s a look at some of the key trends that will be driving breakthroughs and innovation in this exciting field:

Personalized medicine

史蒂夫·喬布斯曾指出21世紀最大的創新將是生物學與技術的融合。如同對所有技術領域的影響一樣，全球疫情加速了生物技術的發展與應用，人們希望這能夠為包括疾病、糧食短缺以及環境破壞在內的重大全球挑戰提供新的解決方案。

以下是推動這一令人振奮的領域實現突破與創新的主要趨勢：

個體化醫療

2 傳統上，制藥建立在“一方萬用”的基礎上，通過試驗來確定哪種配方能夠讓最廣泛的社會群體最大限度地受益。當今，現代基因組學意味著根據個體DNA構成定制藥品配方成為可能。部分原因歸結于2003年人類第一個基因組測序花費約為30億美元，而現在卻只需600美元左右。了解DNA在人們保持健康和身體抗病能力中所扮演的角色，便可以更簡單地預測會發病的人群，更精準地作出診斷，并根據個體遺傳因素進行針對性治療。

2 Traditionally drugs and medicine have been created on a “one-size-fitsall” basis, and trials are used to establish which formulations are most beneficial to the widest segment of society. Today,modern genomics means it’s possible to tailor the formulation of medicines for individuals, depending on the makeup of their DNA. Partly this is due to the fact that while sequencing the first human genome cost around $3 billion back in 2003, it can now be done for around$600. Understanding the role DNA plays in our health and our body’s ability to fight disease makes it simpler to predict segments of the population where illness is likely to occur, make better diagnoses,and create targeted treatments dependent on individual genetic factors.

3 Currently, personalized medicine can be used for understanding factors such as how a person’s genetic makeup affects the way that cancerous cells are likely to grow and spread in their body,meaning better decisions can be made about what treatment should be given.Another common use is in preventative medicine, whereby patients with a particular genetic makeup that’s shown to leave them susceptible to a particular illness can be given pre-emptive treatment. Personalized medicine will be a strong focus throughout 2022, and researchers are confident it will lead to more effective and efficient treatments for many diseases.

Agricultural biotech

3 目前，個體化醫療可以用于了解一些影響因素，比如個體基因構成如何影響癌細胞在其體內生長與擴散方式，這意味著可以更好地確定應當給予患者何種治療。另一種常見的用途是在預防醫學中，對一些因特定基因構成更易患上某種疾病的患者可進行預防性治療。個體化醫療將成為貫穿2022全年的焦點，而且研究人員相信這將有助于更有效、更高效地治療很多疾病。

農業生物技術

4 在農業領域，生物技術應用于開發產量更高、抗病蟲害能力更強的農作物。世界面臨全球糧食危機、數百萬人面臨饑餓風險，此類技術具有潛在的巨大價值。這意味著種植出的食物營養更豐富，危害健康的毒素含量更低。生物技術也將降低農耕對環境的破壞程度，這是由于農作物適應力強，農藥更有效、更具針對性因而使用劑量下降，也就減少了徑流對土壤和水道的污染。它也被用于培育農作物來清除工業活動對土地造成的污染，使土地重新得以耕種——這一過程被稱為植物修復。

4 In farming, biotechnology is used to develop crops that provide better yields and are more resistant to pests and diseases. This has the potential to be hugely valuable in a world facing a global food crisis where millions of people are at risk of starvation. It means food can be grown that is richer in nutrients and lower in toxic content that can be damaging to our health. Biotech will also lead to agricultural practices that are less damaging to environments, as resilient crops as well as more efficient and targeted pesticides will be used in lower volumes meaning less pollution of the earth and waterways from runoff. It’s also being used to create crops that can be used to remove pollution caused by industrial activity from land, enabling that land to be revegetated—a process known as phytoremediation.

5 New types of crops can also be created—one example being the caffeinefree coffee beans created by UK start-up Tropic Biosciences, which removes the need for an expensive, polluting, and waste-creating decaffeination process.2022 will undoubtedly also see further debate around the ethics of biotechnology, with society facing up toquestions around the importance of providing enough food while maintaining standards of food safety and the potential for ecological damage that genetically modified crops themselves might cause to natural environments.

Faster pharmaceutical testing and approval of medicines

5此外，還可以培育新型作物——例如，英國初創企業熱帶生物科技公司研制出不含咖啡因的咖啡豆，從而免去了高成本、高污染且多廢料的脫因流程。社會要正視以下兩方面問題：在提供充足食物的同時堅守食品安全標準有多重要，以及轉基因作物本身是否可能對自然環境造成生態破壞——由此，2022年圍繞生物技術倫理的辯論將更深入。

藥物試驗與獲批加速

6在緊急研發和獲準制造新冠疫苗后，人們在加快新藥試驗獲批的進程中付出了巨大努力。這在很大程度上依賴于生物技術領域的研究成果和數據資料。傳統上，新藥上市要經歷長達十年的審批和認證過程。生物技術數據正加速這一進程，它可以模擬藥物和人體的相互作用，不必每個階段都依賴昂貴且耗時的人體試驗。美國食品和藥物管理局的實時腫瘤學評審項目就是一個納入生物技術數據、大大加快藥物試驗和審評過程的實例，特別是因為其有可能準確預測新型癌癥治療試驗的測試結果。另一個例子是制藥公司渤健推出的首款阿爾茨海默癥藥物阿杜卡奴單抗，由于2 0 2 1年生物技術的進步而進展迅速。我們有望看到更多關于這一領域的研究，希望更快地研發出更有效的藥物和治療方法。

6 Following the emergency development and approval of Covid-19 vaccinations, huge efforts have been made to speed up the process of testing and approving new drugs. Much of this is reliant on research and data originating in the field of biotechnology. Traditionally,new drugs have taken up to 10 years to make it through the lengthy process of approval and certification. Biotech data is being used to speed up this process by allowing simulations of interactions between medicines and the human body,rather than having to rely on costly and time-consuming human trials for every stage of the process. The US Food and Drug Administration (FDA)’s Real-Time Oncology Review program is an example of a drug testing and review process that has been greatly accelerated by the inclusion of biotech data,specifically due to its potential to accurately predict testing outcomes of trials of novel cancer treatments. Another example is pharmaceutical developer Biogen, whose first-of-its-kind treatment for Alzheimer’s disease, aducanumab,was rapidly accelerated thanks to advances made in biotech in 2021. We can expect to see more research in this field,hopefully leading to quicker development of more effective drugs and treatments.

Environmental biotechnology

環境生物技術

7 我們已提到農業生物技術如何更高效地培育作物，從而減少能源的消耗以及農藥對生態的破壞。然而，為了提高生態可持續性并減少對環境的影響，生物技術還有許多其他的應用途徑。這包括創造專門用于分解塑料的生物有機體，使其更有效地回收。2021年，法國卡比奧斯公司設立第一家利用轉基因酶分解聚對苯二甲酸乙二醇酯（PET）的工廠，PET是塑料瓶常用塑料。其他生物技術衍生的酶用來生產新型洗滌劑，此類洗滌劑效能足夠強，可用于工業清洗過程，可完全生物降解，而不像其他工業洗滌劑那樣產生有毒廢物。

7 We already mentioned how biotechnology in agriculture means more efficient crop production, and therefore less energy use and ecological damage caused by pesticides. However, there are a number of other ways in which biotechnology is being harnessed in order to improve sustainability and reduce environmental impact. This includes the creation of biological organisms specifically designed to break down plastics, enabling them to be more efficiently recycled. In 2021, French company Carbios opened its first plant dedicated to breaking down polyethylene terephthalate (PET) plastic,commonly used in plastic bottles, using genetically modified enzymes. Other biotech-derived enzymes are being used to create new types of detergent that are powerful enough to be used in industrial cleaning processes while also being completely biodegradable, rather than generating toxic waste as with other industrial detergents.

8 Another hugely important field where we can expect to see ongoing innovation during 2022 is in biofuels.New processes involving creating clean energy from agricultural and industrial waste—and even algae—are appearing thanks to advances in biotechnology.

Artificial meat

8 2022年，另一個有望持續創新、極其重要的領域是生物燃料。得益于生物技術的進步，利用農業和工業廢料甚至藻類生產清潔能源的新工藝正在興起。

人造肉

9 我們因喜食肉類而對地球產生影響，大量關于減少這種影響的研究正在開展。這導致實驗室培育的人造肉越來越被吹捧為一種潛在的解決方案——至少對于我們當中那些不打算或不愿意改吃素食的人來說是這樣！

9 A great deal of research is ongoing into reducing the impact that our love of meat eating is having on the planet.This has led to artificial and lab-grown meat increasingly being touted as a potential solution—at least for those of us who aren’t ready or willing to switch to a vegan diet!

10 Lab-grown meat involves cultivating tissue artificially from muscle and fat cells and has the potential to hugely reduce the amount of energy, land, and water utilized by the livestock industry—as well as the methane emissions,which are recognized as a leading cause of climate change!

11 The biotech processes for growing meat evolved from techniques originally designed to help repair injuries by regrowing damaged cells in humans or animals—for example growing skin cells to be grafted onto burn victims.A number of companies, including delivery giant Just Eat, are now planning on launching their own artificial meat onto the market, and 2022 could be the year that it starts to become widely available. ■

10 實驗室培育肉類需要用肌肉和脂肪細胞人工培植組織，有可能大大減少畜牧業所消耗的能量、土地和水，以及被認定為氣候變化主因的甲烷排放！

11 培育肉類的生物技術工藝起源于原本旨在讓人或動物受損細胞再生以幫助修復創傷的技術——例如培育皮膚細胞移植到燒傷患者身上。包括外賣巨頭Just Eat在內的很多公司正計劃向市場推出自家的人造肉，而2022年可能成為其開始廣泛普及的一年。 □
