Mind-blowing science factoid of the day: You already knew that it takes ~8 mins for photons to travel from the Sun to Earth (~150 million km). What you’re observing is a past Sun ~8 mins behind its actual position in the sky. However, each photon emitted by the Sun’s core first has to traverse dense radiative and then convective layers before reaching the surface of the photosphere. That journey involves a very slow and inefficient random walk (think Brownian motion and boiling fluid dynamics, respectively) through a dense soup of particles that constantly absorb and re-emit photons in new directions. The process takes between 10,000 and 170,000 years, and no single photon makes the full trip; the new photons eventually leaving the surface are the result of countless energy handovers along the way. This means that there’s a good chance that the energy of the sunlight you see today was generated before Homo sapiens even existed, even if the photons themselves were emitted ~8 mins ago.

Important piece of advice no one has said to me that I’ve discovered in academia: don’t pick things because they’re easy, but because you thought they were easy.

Important piece of advice no one has said to me that I’ve discovered myself during the PhD - pick the parts of the project that can deliver the most outsize impact for the amount of effort put in. So much tall long grass to get lost in

So maybe the body is just following the narrative of its own story after all. https://www.noemamag.com/ai-could-be-a-bridge-toward-diverse-intelligence/

A gentle reminder for anyone who participated in the Chain Reaction challenge. You are eligible for more rewards. I’ll send them out by Monday morning, so get your quote casts into /videolab by the weekend if you wish to participate. For everyone else, this challenge is over. But there may be more down the road. :)

during my last massage session, I started wondering - why do I feel both physically and mentally relaxed? I suspected hormones were involved, and it turns out there's a whole cocktail at play: - oxytocin (trigger: gentle strokes, trust in the masseur, the reassurance they won’t harm you → lowers anxiety) - endorphins (trigger: muscle pressure → blocks pain signals, reduces stress, creates euphoria) - cortisol drops as the hypothalamus-adrenal axis is suppressed through relaxation. Adrenaline levels also decrease. - cytokines, the signaling molecules affecting immunity and inflammation, also shift balance: pro-inflammatory cytokines (e.g., IL-6, linked to chronic stress and pain) decrease. anti-inflammatory cytokines (promoting tissue repair and relaxation) increase. this makes the massage doubly enjoyable

I care way less about the man vs woman thing and way more about : 1. In future, the 200 year old active users of biohacking tech will be rich, interesting, looking young and perfect — they will leave the 20 year old guys completely no chance to outperform. The massive reproduction take over and intolerance would push towards a war of classes 2. AGI to ultimately aim manipulating the reality with purposeful misinformation of people applying the concepts of subjective reality and of collective halicunation

Really interesting paper was just published today reporting you can't outrun a bad diet. Food, not lack of exercise, fuels obesity. They compared the daily total calorie burn for people from 34 different countries and cultures around the world. The people involved ran the spectrum from hunter-gatherers and farming populations with low obesity rates, to people in more sedentary jobs in places like Europe and the U.S., where obesity is widespread and found strong evidence that diet, not a lack of physical activity, is the major driver of weight gain and obesity in our modern world. https://www.pnas.org/doi/10.1073/pnas.2420902122

Visiting a lab and I was really exited to see a machine I’d read about in Nature that demonstrated end to end DNA data storage Little did I know that this much hyped demo now lives under a desk. The reality of science. https://www.nature.com/articles/s41598-019-41228-8

Very excited to announce that we’ve dosed our first patient with our latest next-gen cancer immunotherapy drug which is broadly applicable to most solid tumors! We started working on this one in 2022. It’s really cool to see how quickly a drug can go from an idea into the clinic. https://investors.vir.bio/news/news-details/2025/Vir-Biotechnology-Announces-First-Patient-Dosed-in-Phase-1-Clinical-Trial-of-EGFR-Targeting-PRO-XTEN-Dual-Masked-T-Cell-Engager-VIR-5525-for-the-Treatment-of-Solid-Tumors/default.aspx
