Is Our Food Becoming Less Nutritious?

newtboy says...

I want to know what effect global dimming has had. It's a no brainer to think less light=less nutrient uptake.
Temperature also helps regulate growth rates, and it's changed.
Interesting about co2 making each plant larger with no addition of nutrients. Reminds me of growing redwoods in New Zealand....they grow astonishingly fast there, but the wood is useless because it's so soft.

Why we need a new education system

bobknight33 says...

Bring the issue to light is a good start.

Do they still have Vo Tech schools?

I remember taking
Wood shop
Metal shop
Auto shop
In regular school.

Never went to Vo tech but some kids did.

While I agree with everything he says, he's pointing out a lot of problems without giving solutions.

To improve a system you need to introduce a better method, and ideally a way to transition to it; it's not enough to point out problems with the current one. I'm not saying it's not valuable to point out problems, I'm just saying it's not enough.

Where Brazil Nuts Come From - Weird Fruit Explorer Ep 207

Buttle says...

One of my former cow-orkers, who grew up in Malaysia, told me that when he was young his father was walking through the woods and was hit in the head by a falling Brazil nut -- he came to hours later, and was wicked late for dinner. He described the fruit as having nuts like sectors of an orange.

Nice to see them in fact.

FOUND Missing 12 Thai Soccer Kids Trapped in Flooded Cave

MilkmanDan says...

I've been following this story here. Sure was happy when they were found alive -- I had started to lose much hope after they'd been gone 4+ days.

The bad news today is that a Thai volunteer diver, a former SEAL, died on a return trip from setting up extra air supply tanks along the route. BBC coverage is very good:
https://www.bbc.com/news/world-asia-44734385

Most cave diving experts think that it would be extremely risky to try to move the kids out by diving. One of the on-scene people from the US has said that none of the boys know how to swim, let alone dive, and the conditions in cave diving make it so that panic can quickly lead to disaster.

Unfortunately, a new complication has come up. Oxygen levels in the chamber they are in are now at 15%, down from the usual 21%. They are working to get piping in to supply fresh air, but logistics of that are difficult since they need about 3 miles of piping. And to make matters worse, heavy rains are in the forecast, which will further stress the pumping that they are doing to keep water levels low in the cave.

The Thai head of the Navy rescue operation was quoted today as saying that "At first, we thought the children could stay for a long time... but now things have changed, we have a limited time." If that is correct and can't be resolved (due to dropping oxygen levels, rising water, or whatever), they may have to opt for the risky exit via diving. So definitely not out of the woods yet.

News helicopter follows wrong car during chase

Mekanikal says...

I watched this live since it was in my neck of the woods and it got even crazier. I can't find the footage but this wasn't the only innocent car they followed. There was a couple that unknowingly gave a ride to the female passenger who bailed out of the suspect car.

Melting Spoon in Tea - Periodic Table of Videos

Sagemind says...

All I can think is Wood's Metal.
But I'd think he's know that.

Wood's metal, also known as Lipowitz's alloy or by the commercial names Cerrobend, Bendalloy, Pewtalloy and MCP 158, is a eutectic, fusible alloy with a melting point of approximately 70 °C (158 °F). It is a eutectic alloy of 50% bismuth, 26.7% lead, 13.3% tin, and 10% cadmium by weight.

Mean Tweets – Avengers Edition

NaMeCaF says...

LOL. I dont know why I even bother.

First of all, I'm not even in the northern hemisphere (again, you're bubble) and have no love for Trump or white-supremacists. In fact I'm half Maori so I guess that makes you're whole argument moot.

I really fear for our future with all the closed minded, bubble living idiots like you coming out of the wood-work now.

Payback said:

Nah, I just think you're a closed-minded douche.

The comment I was replying to was about "racism" towards whites. Not sure where non-white on non-white racism comes into this. I just don't believe making fun of, or critisizing, or generalization of whites can be considered racism. We're on top. If someone marginalized by whites marginalizes someone else further down the oppression scale, that would certainly be racism.

As for the Nazi reference, I'm sure you're one of the good ones Trump told us were at Charlottesville.

Marble Machine - Triple Gears Lift

Payback says...

I think I figured out what went wrong, it's supposed to be "marble", not "bowling ball" wood machine.

bremnet said:

Very nice. I had exactly the same design idea, but the modules in my marble wood machine were too heavy to lift.

How To Be More Productive

newtboy says...

Hmmmm.....No diagonal bracing, and barely sunk posts directly in dirt with no footings...this ramp will not last. Pressure treated wood is rot resistant, not rot proof. Putting your head down and getting to work finishes the job faster, but like this ramp, not better. I doubt this would pass an inspection, it's almost certainly not up to code.

The idea is work smart AND hard. If you work stupidly, you'll have to work much harder to fix your mistakes.

Testing the ice

SFOGuy says...

I was taught to:
1) drill or chop holes close to shore first to check thickness
2) Carry a long pole/piece of wood (6 feet plus) so that if you fell, you wouldn't go under the ice (the idea of being swept under ice and not getting back to the hole you fell into...)
3) If going to rescue someone, tie off/get a line around yourself, and spread your body weight out by crawling/using a saucer/pan/kid's plastic sled...and offer them a line, pole, or thrown sleeve of a garment, not your hand.

anyway, looks like it was pond--they just lost some dignity.
