Mind May Be Older Than the Brain | Michael Levin on Life and Intelligence

Michael Levin is a developmental and synthetic biologist at Tufts University whose work sits at the intersection of biology, bioelectricity, artificial life, regenerative medicine, synthetic biology, computer science, cognitive science, and philosophy of mind. He is known for his research on how cells communicate, make decisions, build bodies, repair tissues, and form collective intelligence through bioelectric signals. His work on Xenobots and Anthrobots has opened new questions about living robots, synthetic life forms, biological machines, morphogenesis, basal cognition, cellular intelligence, regeneration, cancer, aging, and the nature of mind beyond the brain.

In this conversation, Michael Levin and I explore whether mind and intelligence are binary or exist on a continuum, why cognition may be much older than brains, and how systems from cells to humans can pursue goals in different ways. We discuss the TAME framework, the spectrum of persuadability, cognitive light cones, bioelectricity, gap junctions, multicellular intelligence, Xenobots, Anthrobots, kinematic self-replication, neural wound healing, emergence, physicalism, mathematics, Platonic space, algorithms, bubble sort, Turing machines, evolution, human creativity, artificial intelligence, regenerative medicine, and the future of biology. This episode is for anyone interested in philosophy, consciousness, mind, intelligence, synthetic biology, developmental biology, AI, complex systems, evolution, and the deeper question of what it means for matter to become alive, intelligent, or aware.

James Hughes on Citizen Cyborg: Interrogate and Engage the World

In 2012, I sat down with Dr. James Hughes, bioethicist, sociologist, and executive director of the Institute for Ethics and Emerging Technologies.

Fourteen years later, the questions we wrestled with have only sharpened.

Why are transhumanist atheists so often drawn to Buddhism? Is optimism rational, or just a posture we adopt to keep moving? What does it mean to redesign the human being, and which democratic institutions are ready to respond when we do?

James does not flinch from any of it. He talks about his first book Citizen Cyborg, the then forthcoming Cyborg Buddha, moral enhancement, animal uplift, and what our actual chances are of surviving the technological singularity.

What struck me most was his refusal to retreat into easy camps.

Not a cheerleader, not a doomsayer. Someone who interrogates the world and engages it on its own terms.

Reliable Detection of SGLT2 Protein by Knockout-Based Antibody Characterization

BACKGROUND: SGLT2 (sodium-glucose cotransporter 2) mediates renal glucose reabsorption, and its pharmacological inhibition exerts cardio-and renoprotective benefits. Despite widespread clinical interest, reliable detection of SGLT2 protein remains challenging due to concerns regarding antibody specificity. METHODS: Eight commercially available anti-SGLT2 antibodies were evaluated by immunohistochemistry and Western blotting using kidneys and hearts from genetically engineered Sglt2-deficient mice and rats. Human kidney tissues, including renal cell carcinoma samples, were also examined. RESULTS: Among the antibodies tested, ab306558 and HPA041603 showed specific immunostaining in rodent kidneys, with minimal background in wild-type tissues and complete absence of staining in Sglt2-deficient samples. However, ab306558 was unsuitable for human samples because of nonspecific staining.

The World in 100 Years FULL EPISODE | Science Fiction Documentary

What will the world really look like in 100 years?

Forget flying cars, impossible megacities, and science-fiction fantasies. This documentary explores a realistic vision of life in the year 2,126 based on current trends in artificial intelligence, climate adaptation, biotechnology, energy, space exploration, economics, and human evolution.

How will cities change as the planet warms? What happens when AI becomes part of everyday life? Will humans live to 120 years? Will neural implants blur the line between biology and technology? Could Mars become a permanent home for thousands of people? And what happens to society when work, truth, privacy, and even human identity are redefined?

Travel one century into the future and discover a world that is both familiar and radically different from our own. A world shaped by the choices humanity is making right now.

From climate-engineered cities and fusion-powered civilizations to Martian settlements, artificial intelligence, genetic medicine, digital consciousness, and the search for life beyond Earth, this is a deep exploration of the most plausible future awaiting our species.

The future isn’t written.

Silver nanoparticles pave the way for precise DNA cutting and joining

DNA is composed of long chains that act as the blueprint for living organisms. In genetic engineering, scientists cut DNA at specific sites and join the resulting fragments to other DNA sequences, enabling applications such as advanced crop breeding, treatment of genetic diseases, and the generation of animal models for drug discovery.

Assembling short DNA fragments requires overhanging sequences, known as sticky ends, to facilitate efficient binding. However, generating sticky ends requires precise cutting at targeted sites, which remains challenging with current technologies.

A Japanese research group has developed a silver nanoparticle-based technology to precisely cut and join DNA at targeted sites, achieving two to five times higher DNA assembly efficiency than conventional restriction enzyme methods. These findings were published in the journal Nucleic Acids Research.

Strategies to boost antibody selectivity in oncology

Antibodies in oncology are being equipped with toxic cargoes and effector functions that can kill cells at very low concentrations. A key challenge is that most targets on cancer cells are also present on at least some healthy cells. Shared targets can result in off-tumor binding and compromise the safety and potential of therapeutic candidates. In this review, we survey strategies that can help direct biologics to cancer sites more selectively. These strategies are becoming increasingly feasible thanks to advances in molecular design and engineering. The objective is to create therapeutics that exploit changes in cancer and leverage the human body infrastructure, enabling therapeutics that discriminate not just self from non-self but diseased from healthy tissue.

Novel synthetic biomolecule degrades disease-related proteins

Northwestern Medicine scientists have developed a novel synthetic biomolecular condensate that can degrade intracellular disease-causing proteins, providing a framework for new therapeutic approaches for a wide range of diseases, as detailed in a recent study published in Nature Communications.

Shana Kelley, Ph.D., the Neena B. Schwartz Professor of Chemistry, Biomedical Engineering, and Biochemistry and Molecular Genetics and the president of the Chan Zuckerberg Biohub Chicago, was senior author of the study.

Targeted protein degradation is an emerging therapeutic strategy that harnesses cells’ own degradation machinery to clear disease-causing proteins. However, achieving this degradation process across different cell types has remained a challenge due to subtle variations in protein structure.

Munk Debate on Gene Editing

On April 21, the Munk Debates convened a special debate about gene editing in Deerfield, Massachusetts for 650 students at Deerfield Academy.

Motion: Be it Resolved, let’s engineer better human beings.

About the Debate:
New powerful engineering technology is already being used to edit human embryos, curing diseases and repairing defective genes before a child is even born. Some welcome this new science as a powerful tool to enhance human intelligence, memory, appearance and physical health. Why wouldn’t we embrace a science that allows people to live longer, healthier, and happier lives? Others warn that this new technology will be used to create designer babies and a new class of genetically “enhanced” elites. It will undermine human dignity and autonomy, and risk unleashing new diseases into the human gene pool. Playing G-d with human nature, critics argue, will result in a dystopian nightmare of our own making.

About the Debaters:
Arguing in favour of the motion was the biophysicist, best-selling author, biotechnology entrepreneur, and the former director of the Program on Medicine, Technology and Society at UCLA School of Medicine, Gregory Stock. His debate partner was the internationally acclaimed strategic philosopher and pioneering transhumanist Max More. Arguing against the motion was the prominent American bioethicist Ezekiel Emanuel, Special Advisor to the Director General of the WHO and a former founding chair of the Department of Bioethics at the NIH. His debate partner was the award-winning educator, author, and Professor of Reproductive Science at University College London, Joyce Harper.
