Leo delivers a rapid-fire trio of hardware stories. First, BYD's Q2 EV dominance: 557,000 passenger EVs versus Tesla's 480,000, with BYD making its own batteries that charge to 90% in six minutes, operate in -50-degree weather, and powering cars priced from $20,000. Jason draws the Toyota parallel — America laughed at Japanese cars in the 1970s until Toyota became the world's largest carmaker. Owen notes that BYD already dominates markets like the Philippines. Second, the NASA Linc mission: a Northrop Grumman spacecraft launched from a Pegasus XL rocket (dropped from a plane over the Marshall Islands) successfully made contact with the Swift Observatory and will use three robotic arms to tug it to a higher orbit, extending its life by a decade. Third, the bad news from NASA's Inspector General: Boeing's Starliner is now projected to be at least ten years behind schedule, prompting a single-sentence dismissal from Jason: 'What's ten years between government agencies?'
BYD sold 557,000 battery electric vehicles in Q2 2026 vs Tesla's 480,000. It makes its own batteries, charges to 90% in 6 minutes, and already dominates markets across Asia, Europe, and beyond. Jason Hiner compares them to Toyota in the 1970s — the moment before America stopped laughing.
BYD sold 557,000 battery electric passenger vehicles in Q2 2026 versus Tesla's 480,000, reclaiming the title of world's top-selling EV maker.
South Korea announced plans to spend $1 trillion on expanded memory chip production and humanoid robot development.
Making the first hour of your day high-cortisol and the last hour low-cortisol is described as the single most impactful daily habit for mood, focus, alertness, stress resilience, and sleep quality.
A Washington University in St. Louis study found that a great night's sleep produces attention-improvement effects effectively equal to Ritalin.
In the 4 to 6 hours after exercise, dopamine and norepinephrine are elevated, making you more alert and better able to focus — unless you've exercised to exhaustion.
The physiological sigh — two big inhales followed by a full exhale — was discovered by physiologists in the 1930s and is the fastest way to reduce autonomic arousal.
Doing just 10 deliberate exhales throughout the day can significantly elevate heart rate variability by the evening, by repeatedly activating the vagal sinoatrial node pathway.
For nicotine to have a genuine cognitive-enhancing effect rather than merely rescuing withdrawal deficit, Huberman recommends using it only once or twice per week at 3–6 mg.
Because vaping can be done anywhere and is more palatable, people consume far more nicotine via vaping than they ever did smoking, potentially making vaping more dangerous in aggregate despite being safer per puff.
Huberman reported that two injections of approximately 100–200 micrograms of BPC-157 eliminated persistent shoulder pain that had resisted months of other interventions.
Huberman reported that on nights he used the peptide pinealon, he achieved 2.5 to 3 hours of REM sleep inside 6 hours — an unusually high proportion normally only found in the final hours of longer sleep.
