Explainer: How Synthetic Biology is Redesigning Life
Synthetic biology (SynBio) is a field of science that involves engineering life for human benefit. It has the potential to reshape many facets of society—from the ways we produce food, to how we detect and cure diseases.
It’s a fast-growing field of science. In fact, by 2026, the SynBio market’s global revenue is expected to reach $34.5 billion, at a CAGR of 21.9%.
While this fascinating area of research is worth paying attention to, it might be daunting to wrap your head around—especially if you don’t come from a scientific background. With this in mind, here’s an introduction to synthetic biology, and how it works.
What is Synthetic Biology?
As we touched on in the introduction, SynBio is an area of scientific research that involves editing and redesigning the biological components, systems, and interactions that make up life. By doing this, SynBio can grant organisms new abilities that are beneficial to humans.
It’s similar to genetic engineering, however, it’s slightly more granular. While genetic engineering transfers ready-made genetic material between organisms, SynBio builds new genetic material from scratch.
SynBio has applications across a myriad of fields, with research covering everything from space exploration to drug discovery. Here’s a look at five of its real-world applications:
1. Medical Technologies
SynBio has a wide range of medical applications, including drug discovery, antibody production, and vaccine innovation (it’s been key in the fight against COVID-19). It also plays a significant role in “living drug” development, which is the use of living microbes to treat chronic or severe illnesses.
2. Sustainable Energies
Biofuel, which is renewable energy that’s derived from living matter, could replace petroleum and diesel in the near future—and synthetic biology technology is helping develop fermentation processes that will produce biofuel more efficiently.
Bioremediation uses living organisms to restore polluted sites to their original condition. This field uses SynBio to try and make the decontamination process more efficient, and to expand the list of contaminants that bioremediation can target.
4. Food and Agriculture
SynBio plays a significant role in cellular agriculture, which is the production of agricultural products directly from cells rather than livestock or plants. These modified foods might have higher nutritional value, or might be void of allergens. For instance, this can be used to make plant-based burgers taste more like meat.
5. Space Systems and Exploration
Synthetic biology and 3-D printing have huge potential to sustain life during space exploration. Using SynBio technology, cells and bacteria could be modified to produce a myriad of materials—from plastic to medicine, and even food—and astronauts could print these synthetically engineered materials on-demand while in space.
Zooming in: the Science Behind Synthetic Biology
Now that we’ve touched on SynBio’s use in a wide range of industries, let’s dive into the science behind it. In order to understand the mechanics of SynBio, it’s important to explore the relationship between DNA and protein production.
Proteins are the drivers of life in a cell—they’re responsible for carrying out all of life’s functions. They are created through a process called protein synthesis, which relies heavily on DNA. Why is DNA so important in protein production? Because it houses all the information a cell needs for protein synthesis.
Once a protein is formed, it embarks on a complex journey throughout the cell, interacting with a number of other proteins and cellular components to perform functions needed for the cell’s survival.
This process of protein production and cellular interaction is an example of a biological system. And it’s this biological system that synthetic biologists investigate, and try to manipulate.
The Five Main Areas of Research
After combing through the literature, we identified five major areas of SynBio research:
- In silico Synthetic Biology
Meaning “via computer”, this area of SynBio research uses computational simulations to design and predict new biological systems. It’s like using a drawing board before starting a project.
- “Unnatural” Molecular Biology
An area of research focused on altering the smallest unit of DNA—nucleotides.
This area of research deals with larger segments of DNA like genes or chromosomes, and sometimes other cell components that interact with DNA. It aims to create new proteins or protein systems and is the most popular area of SynBio research.
- Synthetic Genomics
Focused on altering and manipulating whole genomes (which is the complete set of a cell’s DNA).
- Protocell Synthetic Biology
This field of research aims to construct whole cells. This is a step towards creating organisms that are entirely synthetic
While early research in SynBio struggled to finish real-world projects, innovation in this field has ramped up quickly in the last decade.
Synthetic biology products are becoming increasingly more pervasive in everyday life—so much so that by 2030, some scientists believe most people will have eaten, worn, or used something created through synthetic biology.
Ranked: America’s 20 Biggest Tech Layoffs Since 2020
How bad are the current layoffs in the tech sector? This visual reveals the 20 biggest tech layoffs since the start of the pandemic.
Ranked: America’s 20 Biggest Tech Layoffs This Decade
The events of the last few years could not have been predicted by anyone. From a global pandemic and remote work as the standard, to a subsequent hiring craze, rising inflation, and now, mass layoffs.
Alphabet, Google’s parent company, essentially laid off the equivalent of a small town just weeks ago, letting go of 12,000 people—the biggest layoffs the company has ever seen in its history. Additionally, Amazon and Microsoft have also laid off 10,000 workers each in the last few months, not to mention Meta’s 11,000.
This visual puts the current layoffs in the tech industry in context and ranks the 20 biggest tech layoffs of the 2020s using data from the tracker, Layoffs.fyi.
The Top 20 Layoffs of the 2020s
Since 2020, layoffs in the tech industry have been significant, accelerating in 2022 in particular. Here’s a look at the companies that laid off the most people over the last three years.
|Rank||Company||# Laid Off||% of Workforce||As of|
Layoffs were high in 2020 thanks to the COVID-19 pandemic, halting the global economy and forcing staff reductions worldwide. After that, things were steady until the economic uncertainty of last year, which ultimately led to large-scale layoffs in tech—with many of the biggest cuts happening in the past three months.
The Cause of Layoffs
Most workforce slashings are being blamed on the impending recession. Companies are claiming they are forced to cut down the excess of the hiring boom that followed the pandemic.
Additionally, during this hiring craze competition was fierce, resulting in higher salaries for workers, which is now translating in an increased need to trim the fat thanks to the current economic conditions.
Of course, the factors leading up to these recent layoffs are more nuanced than simple over-hiring plus recession narrative. In truth, there appears to be a culture shift occurring at many of America’s tech companies. As Rani Molla and Shirin Ghaffary from Recode have astutely pointed out, tech giants really want you to know they’re behaving like scrappy startups again.
Twitter’s highly publicized headcount reduction in late 2022 occurred for reasons beyond just macroeconomic factors. Elon Musk’s goal of doing more with a smaller team seemed to resonate with other founders and executives in Silicon Valley, providing an opening for others in tech space to cut down on labor costs as well. In just one example, Mark Zuckerberg hailed 2023 as the “year of efficiency” for Meta.
Meanwhile, over at Google, 12,000 jobs were put on the chopping block as the company repositions itself to win the AI race. In the words of Google’s own CEO:
“Over the past two years we’ve seen periods of dramatic growth. To match and fuel that growth, we hired for a different economic reality than the one we face today… We have a substantial opportunity in front of us with AI across our products and are prepared to approach it boldly and responsibly.”– Sundar Pichai
The Bigger Picture in the U.S. Job Market
Beyond the tech sector, job openings continue to rise. Recent data from the Bureau of Labor Statistics (BLS) revealed a total of 11 million job openings across the U.S., an increase of almost 7% month-over-month. This means that for every unemployed worker in America right now there are 1.9 job openings available.
Additionally, hiring increased significantly in January, with employers adding 517,000 jobs. While the BLS did report a decrease in openings in information-based industries, openings are increasing rapidly especially in the food services, retail trade, and construction industries.
