Researchers are making strides in developing computers that use living cells, a concept that blends biology with computing.
Creating computers from living cells
A small group of scientists, notably from Switzerland, is advancing the field of biocomputing. They envision data centers filled with “living” servers that mimic how AI learns while using much less energy.
Dr. Fred Jordan, co-founder of the FinalSpark lab, describes their work. They use stem cells taken from human skin, which they source anonymously from a clinic in Japan, focusing only on high-quality cells.
Current projects span multiple countries
Dr. Flora Brozzi from FinalSpark explained the process to me, showing tiny white orbs that are lab-grown mini-brains. Although simpler than a human brain, these “organoids” share its essential building blocks.
After months of growing, the organoids can be connected to electrodes, allowing scientists to send and receive electrical signals and monitor the results on standard computers.
Challenges of keeping biocomputers alive
Maintaining biocomputers is complex. Unlike traditional computers, organoids lack blood vessels to supply essential nutrients. Simon Schultz from Imperial College London notes that this is a major challenge in their research.
FinalSpark’s organoids can survive up to four months, but their decline can produce unusual bursts of activity resembling human end-of-life patterns. Dr. Jordan remarks on the emotional weight of their work, acknowledging that understanding these phenomena is part of the research.
