energy density of 175 Wh/kg

CATL explained that sodium-ion batteries have slightly lower energy density than lithium-ion batteries but provide distinct advantages in low-temperature performance, carbon footprint, and safety.

Welcome to Practical Healthspan

Live long and prosper.

Hey — I’m glad you’re here. Practical Healthspan is a space to talk about health in the everyday: better sleep, food that works for you, moving a bit (or a lot), managing stress, staying connected, and trying small experiments. No hype. No pressure. Just what works, backed by science when possible, and real stories when not.

What to expect

• Friendly, curious vibes. We ask questions, share what we try, and learn together.
• When we talk about studies or protocols, we label what kind of evidence it is. If it’s your experiment, we say so.
• Be respectful. Critique ideas, not people. No “one-right way” energy.
• We’re not medical advice. If something’s serious, talk to actual professionals.

If you’re new to the Fediverse / Lemmy please check out some of the links in the community description

Weekly threads you’ll see

• Motivation Monday – What are you focusing on this week, health-wise?
• Study Sunday – We dig into a research paper, pull out takeaways, and a small practical nudge.
• Habit Check-In – Mid-week or end-of-week: what habits worked, what didn’t, what you’ll tweak.
• Food-Prep Friday – Share recipes, meal ideas, what’s helping you eat better without stressing.
• Tools & Gadgets – If you tried a new sleep tracker, app, kitchen gear, etc., share what worked or was meh.
• Reflection Friday – What experiments or changes you tried this week, what surprised you, what next.

Quick rules (so we all feel good here)

1. Be kind. Ideas over insults. No shaming someone’s body, food, choices.
2. If you’re making claims, try to provide sources. If it’s from personal experience, label it.
3. No medical advice. If you are discussing medication, serious health conditions, etc., recommend professional help.
4. Disclose conflicts / affiliations (if you’re selling something, promoting something, etc.).
5. No spam. Keep the vibes helpful.

• Ukraine is stepping up international cooperation in defense manufacturing to maximize production, drive innovation, and protect critical industrial infrastructure from Russian strikes.
• Kyiv launched the “Test in Ukraine” platform to allow international defense companies to learn from Ukrainian innovation and test their new weapons and technologies in real combat conditions.
• Ukrainian companies have also scaled up production and created numerous new prototypes of weapon systems and cruise missiles. Their effectiveness, however, will depend on Ukraine’s ability to mass-produce them and Western assistance in sourcing components.

...

Danish Defense Minister Troels Lund Poulsen announced that Ukrainian defense company Fire Point will begin a production line in Denmark. Fire Point specializes in the production of long-range strike drones and cruise missiles.

...

Ukraine’s experience and innovations have attracted the interest of an increasing number of partners. For example, Gaël Veyssière, the French ambassador to Ukraine, expressed France’s willingness to involve French defense and automotive companies in joint production with their Ukrainian counterparts. A project for the joint manufacture of drones is already in the works ... On September 3, at the International Defense Industry Exhibition in Poland, Ukraine signed a memorandum of understanding (MOU) with the Taiwanese and Polish delegations, focusing on drone production (Taiwan News, September 3). Additionally, Yuliia Fediv, Ukraine’s ambassador to the Philippines, announced that the two countries are working toward signing an MOU on defense cooperation by October. A high-level Ukrainian delegation, including officials from the Ministry of Defense, is expected to visit Manila to discuss the draft agreement and the possibility of jointly producing Ukrainian-style drones, specifically uncrewed surface vessels.

...

The Ukrainian government is seeing increased success in developing its defense industry, particularly through international cooperation in the forms of investments, relocation of production, and the creation of joint companies. Despite bureaucratic, financial, and security obstacles, the Ukrainian defense sector is showing rather positive dynamics and becoming more attractive to international partners ... For the Ukrainian military, this may soon mean that missile and drone production catches up with Russian production. For Kyiv’s international partners, the current environment gives them a chance to gain access to cutting-edge expertise and technologies, as well as to test their own products in real combat conditions.

I'm going to try and bop them with a squeaky hammer to see what happens

I put cheese in the mouse trap, it has to work because their nose is big and they can probably sneef cheese from a mile away.

Conditions

Porridge left unattended on a stove at low heat (setting 1/6). The operator was distracted due to being engaged in unrelated digital activity (consuming social media caontent on Lemmy).

Duration of neglect: over 500 s, sufficient for thermal degradation of the lower porridge stratum.

Outcome

Lower layer closest to the electrical heating element exhibited significantly increased viscosity and adhesion to the pot surface. The material had transformed from a slurry to a semi-solid substance. No signs of combustion detected, but structural integrity severely compromised. Upper layers remained nominally intact, although clearly dehydrated.

Remediation Attempt

Immediate cessation of energy input (stove setting adjusted to 0). Introduction of household grade H₂O to the pot.

Volume: ~200–400 ml, determined through optical estimation.

Manual agitation applied.

Initial results: partial rehydration of upper layers; lower stratum remained non-compliant and semi-solid. In the upper layers, porridge consistency trended toward excessive fluidity.

Secondary Observations

Pot left on a gradually cooling stove plate for approximately 500 s while the operator continued to consume unrelated social media content. Upon reassessment, lower stratum demonstrated reduced adhesion and reintegrated adequately with the rest of the material upon mild agitation. Overall viscosity returned to baseline parameters. Upon sensory evaluation, no major defects were detected.

Verdict: fit for human consumption.

Conclusion

In cases of thermal over-exposure, controlled hydration may restore functional properties of starch-based foodstuffs, such as porridge.

Note: Hydration effects are time-dependent. Immediate results should not be expected. Food chemistry remains unpredictable and fiendishly complex, but simple interventions may mitigate adverse outcomes.

Conjecture: Reaction kinetics likely play a role in amount of time required for adequate remediation to occur. However, a more significant factor could be found in diffusion kinetics instead. Due to the elevated density of thermally mildly dehydrated starch and protein matrix, H₂O will be will only be able to enter the sample matrix at a significantly reduced rate.

Limitations

1. Sample size (n=1) precludes statistical significance.
2. Lack of control group (e.g., identical porridge batch intentionally burned for comparison).
3. No baseline measurements of moisture content, starch gelatinization, or protein denaturation.
4. Potential observer bias, as the researcher was also the individual responsible for the initial neglect.
5. No ethical review board approval was sought, as the experiment was unintentional, unscheduled and involved no human subjects beyond the researcher.

Recommendation

While this incident does not meet the any criteria of even an observational study (n=1, lack of controls, absence of peer review), let alone a controlled study, it does provide anecdotal evidence that hydration may mitigate thermal degradation in starch matrices such as porridge. In order to provide additional clarification to the reaction kinetics of porridge, further study in a controlled environment with replication is required.
