ASeq Newsletter 14 implied HN points 25 Nov 25
  1. Nautilus has been pushing an early-access program and that push seems to have increased market interest by showing the platform can support early-access projects.
  2. A recent scientific demo focused on Tau proteoforms (about 768), which is a useful small-scale result but doesn’t demonstrate the claimed ability to interrogate billions of wells or many different proteins.
  3. Because the demo was small, it’s unclear how well the high-density patterning and machine-learning pattern matching perform at scale, so fuller multi-protein or high-well-count demonstrations are needed.

  3. A new AI model called METAGENE-1 can analyze wastewater to detect pathogens and monitor health risks. This technology could help us better prepare for pandemics in the future.
Rough Diamonds 9 implied HN points 24 Nov 25
  1. We feel like our actions are our own when we can see and understand the choices we make. If we can't perceive our decision-making process, we may feel a loss of control.
  2. There's a time right before we move where our brain shows readiness for action, which is called W-time. This moment is closely linked to when we consciously feel that we have decided to move.
  3. People with certain conditions, like schizophrenia or motor disorders, can experience distorted perceptions of their own actions. They might struggle to sense control over their movements, feeling like some actions aren't truly theirs.

psychotechnology 8 implied HN points 21 Nov 25
  1. The mind is made of semi-independent parts or subagents that have their own ages, goals, and roles, and you can learn to notice and talk to them to get clearer answers about how you feel.
  2. Cultivate your inner system like a garden: practice parts-work sober first, develop your own simple ways of classifying and communicating with parts, and use what fits your mind.
  3. Entactogens (like MDMA) can make parts-work more plastic and compassionate while psychedelics may cause bigger, riskier reorganizations, so approach drug-assisted work cautiously and seek professional help if things get destabilized.
NeuroLogos 58 implied HN points 11 Apr 23
  1. Neuroscientists explore a wide variety of interesting questions about brains and behavior beyond just imitating human intelligence or achieving cognitive enhancement.
  2. There is value in focusing on medium-sized scientific questions that are scientifically well-posed, of general interest, and can lead to more specific experimental questions and philosophical speculations.
  3. Topics like sensory substitution, fading percepts, and hyperacuity offer concrete questions for researchers to investigate, such as understanding how signals in the brain enable new senses, how eye movements affect visual experience, and how human vision surpasses the limits of individual retinal cells.
Rough Diamonds 32 implied HN points 25 Jun 25
  1. Consciousness is all about personal experiences and awareness of self, and it's usually absent during deep sleep or anesthesia. Understanding how consciousness works doesn't require diving into complex philosophy.
  2. There are fascinating phenomena like blindsight, where people can respond to visual stimuli without consciously seeing them, showing that our brains can process information even when we're not aware of it.
  3. Similar to blindsight, there are cases of 'deaf hearing' and 'numb touch,' where individuals can react to sounds or sensations without consciously feeling them. This suggests that perception can happen on different levels, even with brain damage.
psychotechnology 7 implied HN points 23 Nov 25
  1. methylnicotine produces a smoother, milder stimulant buzz with fewer physical side effects, but it often feels flatter and less helpful for focused, productive writing than regular nicotine.
  2. Both commercial products add 80 mg of L-theanine and come in different delivery forms, so the calming additive and format make it hard to judge the pure effects of 6-MN and tolerance is a big confounder.
  3. Public research on 6-MN is sparse and mostly proprietary; some users report lower heart rate or help cutting down stronger nicotine products, but overall it isn’t clearly superior and more study of nicotinic analogues would be useful.
Eat Shit and Prosper 139 implied HN points 31 Jan 23
  1. Natural bacteria like _Bacteroides_ can do important tasks in our bodies better than engineered ones. They have evolved over millions of years and have a complex understanding of their role in our ecosystem.
  2. Engineering probiotics may seem like a safe option, but it often overlooks the richness of existing microbes that might serve our needs without modification.
  3. Working with natural bacteria could lead to breakthroughs in health similar to how domesticated animals have changed human life in the past; there's so much potential waiting to be explored.
Rob Leclerc 19 implied HN points 01 Mar 24
  1. Fear of AI dominance may be influenced by our ego, but future AI-human symbiosis could be positive.
  2. The Default Mode Network in the brain plays a crucial role in shaping our self-identity and consciousness.
  3. As AI technology advances, it may lead to changes in human consciousness, potentially altering our sense of self and cognitive abilities.
psychotechnology 5 implied HN points 26 Nov 25
  1. The mind is like a lattice of beliefs that can get stuck, and adding ‘heat’ lets those stuck parts loosen so the system can settle into a healthier arrangement.
  2. Psychedelics can act as that heat, melting rigid or traumatic beliefs and allowing new, more accurate views to form — but they work best when you intentionally direct the process rather than just watching visuals.
  3. You need skills and safeguards: cultivate tolerance for uncertainty, body-based awareness, and therapeutic practices, start with small doses and good set/setting, and respect that these tools can be both powerful and risky.
