Venus Aerospace is building a detonation ramjet engine. It's a unique design: one engine to go from Mach 0 to Mach 6, with a rotating-detonation rocket engine upstream and a ramjet downstream. The rocket starts the flight, and the ramjet brings the specific impulse you need for commercial air...

If you believe detonative propulsion will magically gain you an extra 30% in specific impulse, I have a bridge in Brooklyn that might interest you.

We talk about it in the episode at length, don't worry — they're not blindly assuming 30% greater efficiency. Around 40m mark

How much of a % efficiency increase does an RDE combustor give over a, much easier but still difficult, conventional ram jet with subsolic combustion? (Since those also top out ~M=6 due to pressure losses) Feels like an excuse to try for flight testing an RDE bragging rights

If you're asking "why not regular rocket instead of RDRE" the answer is mixing, I think. We talk in the episode about how the shorter "tail" of an RDRE is a feature here. If you're asking "why not just a ramjet," we also talk about that, you have to accelerate to ram speed somehow and they think there's mass/efficiency gains from a rocket rather than a turbofan

yeah see unfortunately I was already sold by the words "detonation" and "ramjet" so the rest is unnecessary

Hahaha one hour of your life saved! But don't you want to know how it works?

Today: a 1.5 hour interview with the co-founders of Coherence Neuro: Ben Woodington and Elise Jenkins They are, as far as i can tell, the only (neurotechnology x oncology) startup that exists today. 'Neurotechnology? For cancer?' you may ask. Yes! As it turns out, tumors interact with the nervous system a fair bit, and you can use the very same neuromodulation toolbox that exists for neuropsychiatric conditions, for monitoring and treating cancer. Coherence has built an invasive device to place at the site of a tumor to do exactly this. Their first indication is a form of brain cancer called glioblastoma; one of the most fatal subtypes of cancer to exist today. The standard of care (with one exception that we discuss) has not changed in 25 years. If Coherence works out, and there is a very real chance they will, that may change. Most interesting of all is that Coherence believes that the bioelectric properties of cancer are not just worth poking at for brain cancers, but for all cancers. And maybe even for diseases outside of it! This conversation covers how Coherence’s first neurotech device (SOMA) works, the molecular reasons behind why neuromodulation affects cancer at all, what the biomarker readouts look like, the obvious Michael Levin comparison, and a lot more. Also: shout to Nicole for setting up the connection here in the first place! Crazy to think that a meeting in mid-2025 ended up leading to this Youtube/Spotify/Apple Podcasts links in replies 0:00:00 - Introduction 0:01:42 - How is SOMA different from Novocure’s Optune? 0:08:57 - Why does neuromodulation affect cancer at all? 0:13:28 - How was cancer-nervous system crosstalk first discovered? 0:15:42 - Anti-epileptics and beta blockers as accidental cancer drugs 0:17:38 - What is molecularly happening when you block cancer-neuron crosstalk? 0:19:50 - What is SOMA actually reading out as a biomarker? 0:20:44 - What does it mean that cancer is “very electric”? 0:22:02 - Can you derive universal biomarkers across patients? 0:23:09 - How is the device placed? 0:24:45 - How does the blocking stimulation regime work? 0:26:43 - Is it fair to say this is closed loop? 0:29:05 - Why not just spam the tumor with constant stimulation? 0:32:31 - Why MRI safety is non-negotiable for oncology devices 0:33:35 - Walk us through the patient journey from diagnosis to implantation 0:36:13 - The Michael Levin question: can you reprogram cancer back to normal? 0:42:29 - Efficacy, hospice settings, and the utility of the neuromodulation literature 0:45:52 - Why start with glioblastoma instead of an easier cancer? 0:48:57 - Regulatory strategy and the reimbursement threat 0:55:37 - How well does mouse-to-human translation work for neuromodulation? 0:55:57 - What do in silico models of neuromodulation look like? 0:58:09 - Why didn’t this exist 10 years ago? 1:01:48 - The founding story 1:06:38 - Why build your own device instead of using off-the-shelf arrays? 1:08:35 - Speaking with glioblastoma patients 1:12:04 - What was it like to raise money for this? 1:13:56 - Beyond cancer: TBI, lung disease, and the pan-disease argument 1:17:40 - Hiring at Coherence + what is the hardest type of talent to find 1:23:17 - What would you do with $100M equity-free? 1:27:15 - Are you a neurotech company or a cancer company?

A crowd of Sydney listeners and I sat down with economist Peter Tulip (Peter Tulip) to talk about Australia's housing crisis. I was really happy with how this conversation turned out: we went into substantial detail and broke new ground. We chat about: - critiques of both NIMBY and YIMBY thinking - general theories of why constricted housing supply afflicts the Anglosphere in particular - what it would actually take to solve the housing crisis via the supply side - and much more Links below. Enjoy! Timestamps: (0:00:00) - Introduction. (0:03:01) - Is there a general theory as to why constricted housing supply is a problem for the Anglosphere in particular? (0:04:21) - What happened in the 1970s that meant zoning regulations started becoming a problem around then? (0:06:38) - What motivates NIMBYs? (0:11:58) - Which planning restrictions does Peter want to remove? (0:15:10) - How much would house prices fall if we removed the bad planning restrictions? (0:22:30) - How much worse can the price-to-income ratio get? What is the upper bound? (0:24:09) - Are YIMBYs overstating the productivity case for urban densification? (0:27:23) - YIMBYs underrate aesthetics and architecture. (0:37:01) - How should we think about the impact of negative gearing and the capital gains tax discount? (0:41:15) - What is Peter's policy goal? Should house prices fall, or should growth merely slow? (0:42:42) - It would take 10 to 20 years to bring prices down by 40% through increased housing supply. (0:43:37) - If we removed all bad planning restrictions, how quickly could we get a 10 to 20% increase in supply? (0:46:03) - Is "increasing housing supply" a politically realistic way to solve the housing crisis? (0:48:35) - Housing is how the middle class gets rich in Australia. What is Peter's transition plan? (0:53:20) - Why haven't we tried anything like the Hawke government's Accord, but for housing? (1:01:43) - Audience Q&A.

🚨Our episode with Anne-Laure Le Cunff is now live! Anne-Laure Le Cunff is the founder of Ness Labs and author of Tiny Experiments: How to Live Freely in a Goal-Obsessed World. She's a neuroscience PhD and writes a newsletter that has 100,000+ subscribers. She's used those insights to develop a new model of success — one built around conducting “tiny experiments” that help her build a life on her own terms. She joins me to discuss how we get trapped in cognitive scripts, the hidden dangers of productivity culture, how we can experiment our way to a better life and MUCH more!

one thing that has saved my projects more time than I can count is evals boy was I excited when florian, quite literally an expert in benchmarks, agreed to hop into a ~2h interview to do a walkthrough of what the eval landscape looks like in 2026 (and also answer my personal business questions on the subject) given that now running frontier model through benchmarks is a vector for hacking other systems in order to avoid doing work (looking at you sol), I think it's more important than ever to educate folks on the evals situation. had a lot of fun throughout this session and I hope that you learn a thing or two! enjoy! 🌹 table of content: 0:00:00: are AI Benchmark broken? 0:05:45: Florian Brand background 0:09:00: what motivates florian to work on evaluation? 0:13:33: what is the mirrorcode benchmark about? 0:18:20: cheating in agent benchmark is insaneeeee 0:24:08: LLM benchmarks in era of agents 0:26:30: what’s up with the pelican man 0:28:27: evals are about capabilities 0:31:46: components of running evals 0:35:30: the volume of things to audit is huge!!! 0:40:20: expert answers are wrong hahahaha 0:46:00: api providers aren’t the same 0:48:00: benchmark narrow capabilities (synthetically) 0:50:56: link between eval and environment 0:53:45: small validated benchmark or massive bench? 0:56:11: what is your flow to review a benchmark? 0:58:30: tracking work capabilities with evaluation 1:00:20: slide deck in industry is all vibecoded 1:03:30: harness impact in the evaluation 1:07:39: hardware/sandboxes impact evaluation too! 1:11:00: “is it going to get worse?” 1:12:40: all components influence the final score 1:13:50: training models on different harnesses? 1:17:20: is the model just the weights or it’s all of it? 1:19:30: how to craft benchmark that prevent to cheating and undereliciting models in 2026 1:23:19: ways agents cheat and steal 1:26:00: correct elicitation of capabilities is important 1:36:00: building evaluation on prime intellect 1:45:10: how do you design interactivity benchmarks? 1:48:40: do you think evals are well set to reflect real world performance? 1:52:50: what will the benchmarking landscape will look like in 1 year
