260 산업 Alternative “Meats” Might Be Our Greatest Climate Solution

Burger King’s Impossible Whopper was a roaring success. In 2019, the plant-based burger boosted the restaurant's sales by six percent. Other fast food chains quickly followed in suit: Dunkin’ Donuts offers a Beyond Sausage Sandwich, KFC features Beyond Fried Chicken and Chipotle developed an in-house vegetarian chorizo. Clearly, plant-based meats are all the rage. And they might be the key to protecting our planet. In a new report, experts from Boston Consulting Group (BCG) and sustainability-focused investing group Blue Horizon show that the industry could be one of society’s best tools for reducing greenhouse gas emissions.

259 기술 Screening a new promoter library for use in plant synthetic biology

Plant scientists are actively striving to successfully introduce valuable traits into plants and use them as bioreactors for ‘molecular pharming,’ wherein pharmaceutically useful molecules are produced in living organisms serving as chemical factories. The molecules produced include important therapeutic proteins that can be expressed in a plant by altering its synthetic switches or metabolic pathways. Genetic elements like DNA promoters and terminators are crucial for creating this platform, since they control the expression of the “gene-of-interest.”

258 산업 Bringing Big SynBio to the Big City

New York City is not for everyone. It has a reputation for being crowded, expensive, and frenetic. But it is still, as one writer puts it, the City of Ambition. Having attained preeminence in finance and publishing, NYC is now rising in biotech. Indeed, NYC is starting to vie with the traditional biotech hubs—Boston and San Francisco—for the favor of synthetic biology (synbio) companies, as evidenced by the growing number of synbio startups that have made the Big Apple their home.

255 기술 Reconstructing How the Spine Takes its Shape

For as long as she can remember, Marina Sanaki-Matsumiya wanted to understand the mechanisms shaping the bones that form our skeletons. Born with a genetic skeletal disease, the developmental biologist first established an in vitro model to study the transient mouse embryonic tissues called somites that form the spine.1 She then joined Miki Ebisuya’s laboratory at the EMBL campus in Barcelona as a postdoctoral fellow to continue this work with human induced pluripotent stem cells (iPSCs).2

254 기술 Scientists engineer probiotic to prevent infection of large intestine

Scientists from the Yong Loo Lin School of Medicine, National University of Singapore (NUS Medicine) have created a probiotic to restore bile salt metabolism, found in the gastrointestinal tract, to counter the onset and effects of Clostridium difficile infection (CDI). CDI is the infection of the large intestine or colon that leads to infectious diarrhea, caused by an infectious bacterium known as Clostridium. Most cases of CDI have been observed to occur in those who have been taking antibiotics or just finished their course of antibiotics.

253 기술 Teaching computers to predict efficient catalysis

Researchers have developed a machine-learning algorithm that can teach computers to predict how molecules will bind to the surface and how strongly they will bind. The algorithm can assist in predicting efficiently and accurately whether a given material lends itself as a catalyst for chemical reactions involving many different complex molecules.

252 기술 Metabolically engineered bacterium produces lutein

Lutein is classified as a xanthophyll chemical that is abundant in egg yolk, fruits, and vegetables. It protects the eye from oxidative damage from radiation and reduces the risk of eye diseases including macular degeneration and cataracts. Commercialized products featuring lutein are derived from the extracts of the marigold flower, which is known to harbor abundant amounts of lutein. However, the drawback of lutein production from nature is that it takes a long time to grow and harvest marigold flowers. Furthermore, it requires additional physical and chemical-based extractions with a low yield, which makes it economically unfeasible in terms of productivity. The high cost and low yield of these bioprocesses has made it difficult to readily meet the demand for lutein.

251 기술 Research shows oilseeds’ potential for bioproduct creation.

Plant science is opening up promising opportunities to create environmentally friendly bioproducts — fuels, lubricants and other products that substitute for petroleum-based ones. Researchers with the University of Nebraska–Lincoln’s Institute of Agriculture and Natural Resources are exploring a range of innovative approaches. A key focus involves new types of vegetable oils with fatty acid structures that enable production of biomaterials in significant quantity. To create those oils on the needed scale, scientists first must conduct complex research to understand the oils’ enzymes and genes.
