Turns out there are enough studies for a meta analysis. Is that basic science? I'm not sure what counts. https://www.sciencedirect.com/science/article/pii/S127977072... If amyloid is truly the critical

I'm far, far more interested in anecdotes about completely halting or reversing decline than I am in rock solid data about a 30% reduction in decline speed. Antibiotics started out as an anecdote about something whose effect was so sta

There is anecdotal evidence and perhaps even some small studies showing that a keto diet can halt and even reverse Alzheimer's symptoms. Compared to that, reducing the speed of decline isn't terribly impressive. It's better t

I had this problem on a low power design. We were making an industrial temperature sensor for something that moved and we needed to run on battery. What I ended up doing was using a second voltage regulator with an enable pin for all the ac

> better insulation It's very, very hard to get insulation that's not good for at least 100V and I suspect that just about any generic wire is good for more like 300V. The only exception that comes to mind is wire that's s

Not if you buy older cars. Pre 2010 seems safe enough.

NASAs "do stuff" budget is super small because their "keep all the experts on staff" budget is insatiable. It's not entirely bad though, I'm sure lots of those folks are doing good and important stuff. But I do

This was phrased poorly if I understand the meaning. "If there is limited use, roads are more efficient than rail" That's probably true as roads tend to cost less per mile than rail and you don't have transfer problems.

Okay what's the safe dose of micro plastics? What's the evidence for that dose being safe? Do we have 100 years of data? The reason we know there isn't a safe dose of lead is a lot of study. Every month there's a new s

by msandford 2y ago
The dose makes the poison. I'd choose micro plastics vs an equivalent mass dose of lead. If it was 1000x the amount of micro plastics vs lead it's maybe less obvious which is the less bad poison. I'd have to do some research

I'm assuming they already have done so for years and that the cost is already baked into McDonald's prices. As someone who doesn't eat there often it doesn't really affect me. Am I glad there's a cartel in general?

by msandford 2y ago
Poor McDonald's, getting stomped on by someone else with power. I kind of like that someone is doing to them what they did to customers re: shake machines.

Well I mean folks in the developing world now have mobile phones which is really changing the way things work. It doesn't immediately install a new government and raise everyone instantly out of poverty but it's likely a big impro

Biden has 3.5 years to adjust the policy and only now have the numbers gone up? It's probably not strictly partisan.

The most efficient seasonal battery is probably synthetic hydrocarbons. By the time you get to propane (3 carbons) the pressures for liquid are super super reasonable (400psi including a giant safety factor) and there's zero embrittlem

People have been pointing to a few high activity hurricane seasons as proof positive that it's climate change going to ruin everything. One gets the feeling that there's some kind of maybe linear-ish correlation. The idea that a

Recommendations are optional. There is no enforcement. I might not be able to find a doctor to give me a surgery I want. But rarely does a surgeon force upon someone a surgery they don't want. An obvious counter example is electroshock

Would love to know more about this. How would that happen? What's the process to bring it back up so fast? The video has a lot of good info and seems compelling. During the Texas freeze many power company officials said the exact same

The "turning the grid up to 11" attack isn't really possible. I know it seems like it is, but the inverters will only advance frequency so much before they back off, the inverters will only increase voltage so much. Etc. Soun

Typically if you want to DIY something you first start with the smallest prototype possible and work your way up from there. This demo cell isn't super interesting on its own but to validate the chemistry it's super helpful. Once

I think sugar consumption is a symptom of a deeper problem like food not actually being nutritious anymore and glyphosate on everything chelates what nutrition you do actually get. It's really hard to have self control and just not eat

How so? Would the Federal regulators have done a better job of making CenterPoint invest the right amount of money into tree trimming and placing lines underground? California is under Federal regulation and has significant problems where

I just read the US section and it seems to contradict what you just stated above. If you use incendiary tennis balls it qualifies as a "destructive device" but then it's not really a potato cannon anymore. It also says if you

Pipelines solve this problem quite neatly. The transport cost of a pipeline is very small compared to the fuel transported. Interestingly pipelines can have near perfect fuel efficiency (though few do) since it's possible to run the pu

Ah I see. That analysis works if you neglect the free body diagram of the system. I agree with your analysis if one larger terminal were analogous to two smaller ones. But it is not. When a bolt applies clamp force it does so to every thin

by msandford 2y ago
I don't follow how stacking two terminals cuts the clamping force in half. If a screw provides 10lbs of clamp force, the equal and opposite reaction is that the thing it is screwed into must resist with 10lbs. If you put one terminal i

Is that nameplate or actual usable solar? In Texas or Spain the solar capacity factor is about 0.2, in Germany it's probably 0.15 or less. So if it's nameplate equivalent but with nuclear capacity factor of 0.9 or more you'd

Environmentalism suffers from the same "purity test" mindset as other things these days. Better than incumbent alternatives is nowhere near good enough. It has to be blameless now and forever. It's really too bad because perf
