Two startups at Vitalist Bay are building 'bodyoids' — headless biological sacks of organs that could replace failing human hearts, livers, and kidneys. The concept raises immediate philosophical alarm: if you replace enough organs, are you still you?

Sarah Todd, a health reporter for STAT News, went to Vitalist Bay expecting a sea of Bryan Johnson-style tech billionaires and found something more nuanced. The Berkeley-based conference, only in its second year, draws investors, researchers, and general wellness enthusiasts — and has a notably diverse crowd, including significant numbers of women and people of color. [1] — Sarah Todd "Vitalist Bay is a Berkeley-based annual gathering for the longevity movement — part science fair, part lifestyle festival. Attendees range …" 02:39 Todd discovered that attendees aren't primarily afraid of dying; instead, they're acutely aware of death and worried that the average human lifespan simply isn't long enough to do everything they want. Many had personal stakes — relatives with Alzheimer's or dementia — driving their interest in healthspan as well as lifespan. One company on the expo floor, NeuroAge, claimed its MRI and blood-test combination could measure brain biological age and that its founder had grown her own hippocampus by 1.5%, though the company acknowledged its methods aren't yet clinically validated.
Vitalist Bay is a Berkeley-based annual gathering for the longevity movement — part science fair, part lifestyle festival. Attendees range from tech workers to researchers and investors, and the crowd is more diverse than the billionaire-bro stereotype suggests.
Sarah Todd found the Vitalist Bay longevity conference more diverse than expected, with a fair number of women and people of color, not just tech billionaires.
The founder of longevity startup NeuroAge claimed to have grown her own hippocampus by 1.5%, though the claim is not clinically validated.
Social norms compress behavior so effectively that we assume other minds are similar to ours. They almost never are. After running over 100 psychology studies, Greenberg's biggest finding is that humans are far more different from each other than we intuitively believe.
The widely shared claim that we have a credit card's worth of plastic in our brains may be a massive overestimate. Researchers used nitrile gloves to measure microplastics — and nitrile gloves shed microplastic particles onto the measuring device. A second paper found the original tool used was unreliable, and that we may have far less plastic than reported.
RSD isn't just hurt feelings — it's a dopamine-deficient brain with a hyperactive amygdala and a frayed connection to the prefrontal cortex. Add a surge of norepinephrine and you get chest pain, sweating, and trembling that convinces your body something catastrophic is happening.
In Dan Ariely's door experiment, participants sacrificed the highest-reward door — repeatedly — just to avoid seeing other doors disappear. Even when researchers trained them to use the best door, they kept wasting clicks to maintain options. This is the bias that runs our lives: we'll take a worse outcome to preserve the feeling of optionality.
Dan Gilbert discovered that the brain has a 'psychological immune system' — it misremembers, reframes, and rationalizes to keep you satisfied with whatever you chose. The fear before commitment is all about potential regret. But after committing, your brain quietly starts justifying the choice — and the more irreversible the decision, the stronger the effect.
The psychological immune system can get you through the first few months of any commitment. But durable, long-term well-being requires self-concordance — choosing commitments that are genuinely aligned with your values and what you actually want. Without that alignment, the satisfaction fades fast.
Vision didn't just help animals find food — it ignited the Cambrian explosion of speciation. Half of the human cortex is devoted to visual processing, and that same visual hierarchy directly inspired the neural network architectures powering today's AI.
Peptides come loaded with a powerful narrative: regenerative, subcutaneous, targeted, cutting-edge. That narrative can genuinely move outcomes, especially for pain, energy, and recovery. The RCT's job is to quantify how much additional benefit comes from the molecule itself — above and beyond the compelling story surrounding it.
A pharmaceutical is not an amino acid sequence — it is the successful solution to manufacturing, purification, formulation, and consistency challenges. When clinical trials prove a drug works, they validate a specific product under specific processes, not every preparation that shares the same sequence.
