Sleeping with even a little light promotes diabetes

Just one night of exposure to 100 lux (equivalent to a streetlight shining through a curtain) during sleep impaired glucose tolerance the next morning. It also "increased heart rate and sympathetic [nervous system] activity during the entire sleep period." 

This was studied in 20 healthy young adults 18-40 years old, and the moderate-light condition was four 60-watt incandescent overhead ceiling light bulbs (a total of 100 lux).

Why do we stretch when we wake up?

We stretch when we wake up to reset our muscles and nervous system after hours of stillness. This instinctive behavior—known scientifically as "pandiculation"—promotes blood circulation, lubricates joints, and primes the brain for movement.

Resetting the Body: During sleep, your muscles relax, blood pressure drops, and joints can become stiff. Stretching signals the brain to awaken from its low-power state and increases blood flow to warm up stiff tissues.

Lubricating Joints: Movement stimulates the production of synovial fluid, which acts as natural lubrication for your joints to prevent pain and stiffness.

Rebooting the Nerves: Pandiculation is a three-step process (contraction, release, and lengthening) that reboots the nerves and muscle spindles controlling muscle tone, helping you achieve better posture and mobility for the day.

Releasing Feel-Good Chemicals: Stretching stimulates the release of endorphins, naturally boosting your mood and easing the unconscious physical tension that can build up overnight.

This process is controlled by the hypothalamus and involves the release of chemicals like cortisol and dopamine, which give you an energetic jump-start, inducing reductions in chronic stress severity and reduced cortisol. 

Has the beneficial effect been studied prospectively? 

Forcing people to transition from a brief, instinctive morning yawn-stretch into an intentional, structured stretching routine significantly improves physical, mental, and vascular health.

-regular static stretching physically reduces stiffness in major arteries.

- 10 minutes of daily stretching counteracts muscle degradation and prevents drops in explosive muscle performance caused by prolonged sitting or sedentary lifestyles.

-Overnight, muscle fibers naturally shorten and tighten. Holding a stretch for the physiologically optimal 30 seconds forces these fibers to physically lengthen, improving overall range of motion and long-term posture.

SpaceX IPO doubts

Trading view had an article about the SpaceX IPO - maybe wait a bit. 

Space company has never been profitable; posted a 2025 loss on tiny revenue and a Q1 2026 loss on, again, tiny revenue. The valuation target? Gargantuan.

IPO Dreams

SpaceX finally cracked open the vault and revealed its financials ahead of what could become the biggest IPO in market history (likely coming in June). The company is reportedly eyeing a valuation north of $1.5 trillion and could raise more than $80 billion in a Nasdaq debut under ticker “SPCX.”

Investors expecting a money-printing rocket factory got a bit of atmospheric turbulence instead. SpaceX lost $4.9 billion in 2025 on $18.7 billion in revenue. In Q1 2026 alone, losses hit $4.3 billion on just $4.7 billion in sales. That's not exactly "to the moon" accounting.

The prospectus confirms what many suspected: SpaceX is really two businesses stitched together with titanium bolts and ambition. One is a mature launch-and-satellite operation. The other is a cash-hungry Al chatbot operation after the merger with xAl, which has been burning through billions building data centers.

Starlink Pays

SpaceX's legacy space operations brought in $4.1 billion in revenue last year, though they still weren't profitable. Meanwhile, Starlink - the satellite internet division generated a chunky $11.4 billion in revenue and continues to be the company's financial workhorse.

Then there's xAI, Elon Musk's artificial-intelligence venture folded into the broader empire earlier this year. xAl generated $3.2 billion in revenue in 2025, but investors are laser-focused on its aggressive spending as it races against rivals in the Al arms race.

In market jargon, this is a “growth-at-all-costs” story. Investors are being asked to ignore today's losses in exchange for tomorrow's potentially massive dominance in Al, space infrastructure, internet connectivity, and maybe Mars Wi-Fi subscriptions somewhere down the line.

Musk, the Unfireable

If investors hoped public ownership might dilute Elon Musk's influence, the filing said: absolutely not. Musk controls roughly 85% of the voting power thanks to supervoting Class B shares carrying 10 votes each. In practice, SpaceX will remain firmly in Elon's grip.

The filing also revealed Musk owns 849 million Class A shares and 5.6 billion Class B shares. Combined with insider holdings, executives and board members control about 86% of the company's voting power. Activist investors need not apply.

There's also a lockup twist. Musk and major insiders agreed not to sell stock for 366 days after trading begins, while other early investors face a 180-day lockup. In short, that's plenty of hype, limited float, gigantic valuation, and volatility potential dialed all the way up.

Compassion

10 times as many people live alone today as compared to 1950.

"In 1950, 22 percent of American adults were single. Four million lived alone, and they accounted for 9 percent of all households […] Today, more than 50 percent of American adults are single, and 31 million — roughly one out of every seven adults — live alone…People who live alone make up 28 percent of all U.S. households,  https://www.themarginalian.org/2012/05/09/going-solo-klinenberg/

And, when we do interact with others, it's much more transactional. 

People in helping professions can develop defensive dehumanization to prevent emotional overload of having empathy. 

47:50

Often when we encounter someone who is different from ourselves or has an opinion that we abhor, It's easy to view them as being either obtuse or dishonest or both. But that's a mistake. It's a view of the world that psychologists call a naive realism. Empathy is the understanding, at a deeper level, that someone else's view of the world is just as true as yours.https://www.hiddenbrain.org/podcast/you-2-0-the-empathy-gym/

Key Takeaways

• The "Muscle" Analogy: Much like going to the gym builds physical strength, deliberate practice can expand our ability to understand and share the feelings of others. [1, 2, 3]
• Benefits of Empathy: Building this skill doesn't just help those around you; it lowers your own stress, reduces the likelihood of depression, and helps you adjust better to difficult situations. [1]
• Mindful Calibration: The episode discusses how we often struggle with empathy fatigue or misdirected sympathy, and teaches methods to calibrate it so we can interact with others in a healthy, mindful way. [1, 2]

He refers 2:15 to a paper on tetrachromacy (people who have a 4^th set of retinal cones, and are neurologically wired to use them.)

Proving someone has tetrachromacy requires asking a subject to mix red and green light until it looks identical to a reference yellow. Trichromats (normal people) all agree on one specific ratio. A tetrachromat, having a fourth cone type in between, perceives a subtle difference in those "identical" mixtures that trichromats can't, requiring a different mixing ratio entirely.

Although about 12% of women have this 4^th cone type, only a very small proportion of them are able to use the extra come to distinguish more color types. ref

Robots working in close proximity to humans safely.

The End of the Cage: How Robots and Humans are Finally Working Side-by-Side

For decades, the "safety protocol" for industrial robots was simple: a giant steel cage. If a human stepped inside, the power was cut. It was safe, but it was also slow, rigid, and physically demanding.

As we move through 2026, we’ve entered the era of Human-Robot Collaboration, where multi-ton machines and human workers share the same floor, often working on the exact same part at the exact same time.

Here is how we’ve moved from "reactive stopping" to "intelligent collaboration."

1. Meet the Cobot

The foundation of this shift is the Cobot (collaborative robot). Unlike traditional industrial robots, cobots are designed with rounded edges, hidden pinch points, and specialized internal sensors.

However, being "collaborative" isn't just about the hardware—it’s about the mode of operation. A robot is only truly collaborative if it is governed by one of the following safety pillars.

2. The Four Pillars of Collaborative Safety

To keep humans safe without cages, engineers rely on four distinct, verifiable methods:

Safety-Rated Monitored Stop: The most basic level. The robot operates at full speed but halts the instant a human enters its "yellow zone."

Hand-Guiding: Think of this as the "power steering" of robotics. A human can grab the robot arm and physically lead it to teach it a new path.

Speed and Separation Monitoring (SSM): The robot uses 3D vision, LiDAR, or radar to calculate the distance to a human. The closer you get, the slower it moves.

Power and Force Limiting (PFL): This is the "gold standard." The robot’s joints contain torque sensors that detect even a light touch. If it bumps into you, it instantly dissipates its energy so the impact is no more painful than a gentle tap.

Watch: Combining SSM and PFL for Safe Collaboration – A biting lecture and deep dive into how robots use math to decide when to slow down vs. when to limit force.

3. The Future: E-Skin and Predictive Engines

The newest developments in 2026 have moved beyond just "sensing" a human to "understanding" them.

Electronic Skin (E-Skin)

Modern robots are now being outfitted with tactile "skins” — thin, flexible sensor arrays that give the robot a sense of touch over its entire body, not just its "fingers." This allows a more nuanced response to accidental contact.

Predictive Safety Engines

The most exciting breakthrough is the shift from reactive to predictive safety. Using Edge AI and 3D depth cameras, robots no longer wait for you to move before they react — they analyze your body language and walking path to predict where you are about to move, adjusting their own path to stay productive while keeping you safe.

Watch: How E-Skin Makes Robots Intuitive – See how touch sensors allow robots to feel pressure and adjust their strength in real-time.

4. Safety is Software, Not Steel

In today's factories, safety is no longer a physical barrier; it’s a living, breathing software protocol. As robots become more mobile and more humanoid, these standards—like ISO 10218—ensure that technology adapts to us, rather than forcing us to stay behind a fence.
