As an aussie kid I bought into the whole sunscreen hype, but after more than half a dozen failures/partial failures. I've pretty much given up on the stuff (excluding areas that are difficult to protect fully with coverings, neck&

Everything leaks hydraulic fluid, it's just an inherent property of any system with dynamic seals. https://www.youtube.com/shorts/d3ruv-IsGMo

Got to say the pictures of the hydraulic drum (and pump) in the DoD report are very confidence uninspiring.

Quoting ChatGPT (and after a quick sanity check), The F-35 Joint Strike Fighter uses a specialized hydraulic fluid that’s based on a synthetic ester formulation, not a petroleum-based fluid. Specifically, it uses phosphate ester–based fire-

Likely contamination of ground handling equipment [1]. Unfortunately can happen. I wonder if the hydraulic fluid is hygroscopic or something? 1. https://www.pacaf.af.mil/Portals/6/documents/3_AIB%20Report....

Honestly the long-term consequences of Baumol's disease scare me more than some AI driven job disruption dystopia. If we want to continue on the path of increased human development we desperately need to lift the productivity of a whol

Yeh I think this is less of a story about Chinese exceptionalism and more a story of structural issues in the west (I will always admire the Chinese technocrats but lets not get ahead of ourselves). Fossil fuel barons and vested interests h

Shifting waking time forwards is straightforward but getting into bed early enough can be tough. As for the phase shift, I've always had what I thought was maintenance insomnia but at some point I realized I always waking at exactly 4:

I wonder if a similar technique could be used for Melatonin in saliva so that noninvasive circadian phase testing could be performed outside of the lab. I'm convinced that if we actually looked at the circadian phase of the general pop

I suffered from an eating disorder a very long time ago that shared a lot of the same mechanisms (thankfully my starvation survival instinct was stronger). A healthy relationship with exercise does not look like this and I hate seeing this

If a treadmill was my only option. I straight up wouldn't run. If you hate running and you've only tried it on a treadmill, highly recommend giving it another try somewhere nice outside.

I've been running five miles roughly every other day for fifteen years. If I've got a flu or not feeling great I'll take a few days off, no loss. Not sure how one would objectively determine "stamina", but my restin

I always liked the bit where they often compensate folks not directly financially but rather with a generous share in what they are building. Eg. the building containing your one bedroom apartment gets torn down by developers and as compens

I couldn't be assed to do the math, not just chromosome size but also number of genes etc, get's tricky to quantify. Fascinating to think about the variability introduced by having only a single copy of the X chromosome. Lot'

Whats interesting to me is that along with the autosomes (chr1-22) the sperm contributes either an X or Y sex chromosome. The X chromosome is large and carries a lot of important genes. The Y chromosome on the other-hand is much smaller and

I doubt chemotherapy drugs have a favorable risk/benefit ratio. The original article notes that somatic DNA changes might be involved, so perhaps immunotherapy might be useful. Interestingly this is being studied [1]. 1. https:/&

Honestly it's probably just because the condition responds well to hormonal therapy. If you've got a cheap and effective treatment available for a condition it's hard to justify spending research dollars on digging deeper int

Unlike SMR's the efficiency/economics of solar are not as dependent on scale. Even small solar installs can be productive.

Because they were built over centuries, like natural selection, only the best/most practical survived the test of time. Lot's of rubbish was built as-well, it's just not standing anymore. Also car centric urban design is IMO

Looks like London is on track to deploy similar technology. They did a trial in Croydon recently that was considered a huge success. From what I understand they actually ended up with pretty decent buy in from the locals as it had a noticea

Axle weight is a really good point tbh, if you don't have to pay labor costs for the driver it'd make a ton of sense to downsize. Ideally this would be accomplished with taxes on gross vehicle weight. Would make smaller vehicles i

From some googling it appears a major reason for the community shuttles is that they are allowed to operate on narrower, suburban streets than full sized busses and have lower fuel consumption per mile. I'll concede geography limits ar

So the public transport authority stops running their own vehicles, and instead places tenders for individual routes? And anyone can bid on operating the route? I mean they already do that with subcontractors for contingencies etc. Overwhel

I'm not really aware of many rich countries that operate minibusses in urban areas. The bulk of the cost of operating public transport is labor so there's a strong incentive to scale. Now if we get Waymo style self driving minibus
