Researchers led by neuroscientist Sergiu Pașca have created mice with human brain cells transplanted into genetically modified cortices, showing improved cognition in maze tests and raising ethical concerns about cross-species brain research.
Fossil fuel price spikes due to the conflict in Iran are driving up fertilizer costs, threatening global agriculture, but companies like Pivot Bio offer cost-competitive microbial alternatives that bypass these price fluctuations.
The newsletter discusses engineered microbes for sustainable agriculture to reduce fertilizer reliance and critiques OpenAI's safety culture following a Hugging Face hack.
Engineered microbes with genetic switches could reduce reliance on chemical fertilizers, cutting greenhouse gas emissions and farmer costs. Startup Switch Bioworks is trialing this approach by allowing microbes to thrive before producing ammonia for crops.
Researchers have found a way to operate two separate genetic codes simultaneously, avoiding the need to re-engineer every gene in an organism's genome and potentially accelerating synthetic biology work.
Scientists have achieved startling precision in editing genes within human embryos, marking a significant advancement in genetic engineering.
MIT associate professor Kevin Esvelt and team are using genetic engineering on mice to reduce Lyme disease transmission on Nantucket. The 60 Minutes segment details the severity of Lyme disease and the innovative approach to combat it.
Researchers engineered a mutant connexin hemichannel pair that exclusively forms heterotypic gap junctions, enabling selective long-term modification of specific neural circuits.
