Colossal’s de-extinction bid stirs science and ethics debate

Dallas-based Colossal Biosciences is pursuing revival of extinct species—including dire wolves and the dodo—using ancient DNA and CRISPR. The effort has drawn praise for pushing conservation tech and public engagement, but also sharp criticism from scientists who question feasibility and ecological risks, warn against conflating revived animals with extinct ones, and worry about undermining habitat protection; supporters see potential conservation benefits and genetic diversity applications, while critics urge caution and rigorous science.

Gene-edited fungus could turbocharge meat substitutes and slash environmental footprint

A gene-edited fungus used to make mycoprotein grows protein nearly twice as fast with far less sugar after deleting two genes with CRISPR to thin its cell wall; lifecycle analyses across six countries show substantial reductions in climate emissions, land use, and freshwater pollution, plus improved essential amino-acid quality. Regulators and large-scale production hurdles remain before it reaches diners.

Silicon Valley's high-stakes bid to design future babies

Silicon Valley's high-stakes bid to design future babies

Silicon Valley-backed startups are marketing embryo screening and editing services that claim to predict or enhance traits such as IQ and height for around $50,000. Backers include OpenAI’s Sam Altman, Peter Thiel and Brian Armstrong, while critics warn these efforts could create a privileged class of genetically enhanced humans and raise profound ethical and safety concerns. The piece cites experts who question the science, legal bans on human embryo editing in the US, and pioneers like He Jiankui as cautionary precedents, highlighting the tension between autonomy and potential inequality as the race to ‘accelerate evolution’ faces moral scrutiny.

India's First Gene-Edited Sheep Tarmeem: An Update

India's first gene-edited sheep, Tarmeem, has turned one year old and is thriving, showing increased muscle growth due to CRISPR technology targeting the myostatin gene. Researchers aim to use this technology to enhance meat production sustainably in Kashmir, potentially revolutionizing local agriculture and addressing food security issues. The project marks a significant step in applying gene editing in livestock within India, though regulatory and ethical considerations remain.
