Ben Lam, the CEO of Colossal Biosciences, shares his vision for de-extinction technology, aiming to bring back animals like the dodo and woolly mammoth. He discusses the ambitious projects and the innovative business model blending conservation with cutting-edge science. In contrast, ethicist Melanie Challenger raises concerns about the moral implications and potential consequences of reviving extinct species. The engaging debate between bold aspirations and ethical dilemmas captivates listeners, highlighting the complexities of modern conservation efforts.
Colossal's de-extinction project raises ethical concerns, mainly regarding the use of living relatives for reproduction and potential ecological risks.
Breweries like Adnams are leveraging advanced technologies, such as reverse osmosis, to create flavorful alcohol-free beers that cater to the sober market.
Deep dives
The Ambitious Quest for De-Extinction
A US biotechnology firm, Colossal, is undertaking an ambitious and controversial project to resurrect extinct species like the woolly mammoth, dodo, and Tasmanian tiger. The goal is to reconstruct their DNA to create a genetically engineered organism with some of their characteristics, though this process does not exactly replicate the original species. With over $400 million in funding, Colossal aims to use synthetic biology and genetic engineering not just for de-extinction but also for the development of new technologies that can aid in conservation efforts. These innovations can lead to breakthroughs in various fields, including disease treatment and environmental conservation, thus shifting conservation funding towards technology development to combat biodiversity loss at an accelerated pace.
Ethical Concerns Surrounding De-Extinction
Critics of de-extinction argue that the concept is fundamentally flawed, raising significant ethical and environmental concerns. Melanie Challenger, an ethicist, points out that creating a so-called pseudo-mammoth involves using the wombs of living relatives, like elephants, which poses moral dilemmas about consent and welfare. Moreover, the idea of de-extinction may mislead the public into believing that extinction can be reversed, potentially detracting focus from current conservation efforts needed to protect existing species. Challenger warns that the long-term consequences of such projects could lead to more significant ecological disruptions rather than the restoration of biodiversity.
Innovations in Alcohol-Free Beer Production
The growing demand for alcohol-free beer is prompting breweries to adopt advanced technologies to cater to sober customers. Adnams, a UK brewery, has developed an alcohol-free version of its popular Ghost Ship beer by utilizing reverse osmosis, a method that helps retain the original flavors while removing alcohol. This technique involves filtering the beer through membranes, allowing it to maintain its taste without the alcoholic content. Additionally, the alcohol extracted during this process can be repurposed to create other flavored beverages, showcasing a resourceful approach to meet consumer preferences while addressing the rising trend of sober living.
It sounds like a Hollywood movie - bringing extinct animals like the dodo back to life - but a company has attracted hundreds of millions of dollars of investment to do just that. We hear the arguments for and against de-extinction technology.
Also, losing the alcohol but keeping the taste, our reporter takes a sober dive into the tech behind alcohol-free beer.
