I recently read somewhere that it’s actually just very few bee species that die after stinging, among them honeybees. They have a barbed stinger that gets stuck while most bees have flat stingers and can sting repeatedly.

I assume that the submarine producer gives stats like empty weight from which the current weight can be calculated.

However, weight isn’t the important thing in a sub. It’s the weight to volume ratio, or buoyancy.

A sub sinks when buoyancy is negative and rises if the buoyancy is positive.

There are three common ways to achieve the changing buoyancy: the most simple one is a vessel with positive buoyancy adding droppable weights until the buoyancy is negative.

Other ways are a neutral buoyancy vessel that uses it’s engine power to push itself up or down. Or a vessel that can change it’s buoyancy by filling up tanks with water (to reduce buoyancy below neutral) and blow them out with air or other gases lighter than water (to raise buoyancy above neutral). A combination of several methods is also possible.

As I understood it, the dashed line is just the 35°C wet bulb temperature line.

I think it’s the “old assumed border of survivability” and don’t know if it is based solely on mathematics or on other experiments as well.

I also don’t know on how many individuals the new line is based and what age group the older people one is.

The article is about an experiment, where people are exposed to 35°C wet bulb temperatures, but in different settings. Sometimes lower temperatures but higher humidity, sometimes vise versa, but always 35°C wet bulb temperature.

So far the assumption was, that humans can’t survive a 35°C wet bulb temperature for longer than 6 hours. And at current warming this is unlikely to be naturally the case within this century.

However the experiment gives hints to believe that humans can’t survive at lower wet bulb temperatures either. It looks like with lower temperatures and higher humidity, humans can get very close to that 35°C wet bulb temperature, however people seem to struggle more with higher temperatures and lower humidity.

A possible explanation could be, that while more sweat evaporates in lower humidity, the body has a limit for how much sweat it can produce. And if you keep raising the temperature, that the human body simply can’t produce enough sweat to cool itself.

That’s pretty much what I took away from the article. They mentioned they experiment with several people, however the article was mainly about on person in the experiment, a 30ish year old, athletic male.

Edit: add some graphs from the article. Sorry for low quality, but as you said, the layout is quite atrocious and on my phone it keeps jumping around on it’s own, so I lost patience.

I know you’re right, have read it elsewhere before. But I can’t figure out why that would happen. I doubt Earth is loosing mass. Does the moon slow down over time due to impacts or what causes this?

I use mosquito coils, they are very effective.

I also have an electric bat, although it’s more for the phycho fun of killing than helping reducing bites. They are just too many.

I tried lemongrass as a natural deterrent but had the impression it made no difference.

What works best for me is: slapping those you can while not caring about the rest. Because once you start to scratch it’s a vicious cycle, so I don’t touch stings and usually then forget about them shortly after.

Maybe they are different. I live in Asia. From what I heard there are many mosquito species, but the majority not blood sucking or at least not human blood sucking. Only few species carry disease, if I recall correctly.

To be fair, when I’m preoccupied, I also don’t feel them always. Or I feel them but my hands are busy, so I can’t slap them. I often have this at night, when I’m playing PC games and my feet get stung up. It’ll be like “ouch, my foot! Gotta slap that mosquito, but first I finish this in game. And then this.” Procrastinating until it’s too late.

I believe ankles are prime for them due to thin skin.

One mosquito died, writing this comment.

I disagree. I live in mosquito land and get bitten a lot. I’d say the majority of mosquitos biting me, I feel when they land, before they bite. Probably half of those I can either slap or miss and they take off again and try again. There are some spots though where I don’t feel them land. The annoying ones are those I feel touching me but they don’t land, they just fly around. Those are hard to slap.

Unrelated question: does anybody happen to know if the biting time matters for transmitting disease?

2 mosquitos died on me while typing out this comment.

You’re right. I didn’t even notice the second jeep before. It looks like this was done on purpose, which is kind of stupid, especially on the jeep driving behind the other. The grill is there to protect the radiator from debris. Once the radiator gets hit by a a small rock and starts to leak, which can happen quickly, as they are usually made of very thin metal, you’d have to constantly monitor engine heat and fill up cooling water regularly.

This was an accidentally duplicated comment due to poor mobile data service in my area.

I don’t think this would improve cooling, as the bottleneck of airflow is probably the radiator, not the grill.

All I can guess is that the grill was damaged and removed.

Edit: accidentally commented this twice due to poor mobile data service.

Unfortunately my hardware is too old to play games that are like that.

But I’ve noticed the same with mobile games. My policy is: if that single player game doesn’t start without internet access it gets deleted.

I would go even further and say that the perception of the voters outweighs reality.

Ironically education is a good way for people not to radicalize, I believe.

Thank you for the detailed explanation!

I see. Yes I watched the debate and he really didn’t do well, like he was on some medicine and partly asleep. My favorite part was when they discussed who is better at golf. Was a very important thing to get clear for people like me, that are worried of climate collapse.

But this isn’t new to Biden, is it? Confusing names and numbers has always been a Biden thing, I think, it’s not necessarily a health decline. Like my favorite American president quote is “America is a nation that can be defined in a single word: ashofootnae ehfoot, excuse me, at the foothills in the Himalaya…”

That’s why I thought the democrats had a meeting after the debate and saw that Biden’s campaign is not going well and the public thinks (doesn’t matter if rightfully or not) Biden is too old and mentally declining. Maybe, in order to save the sinking ship, it’s best to play a rather risky move of changing the nomine just a few months before election. Or maybe he was also peer pressured.

Anyway, if it was Biden’s initiative he does deserve a lot of respect for it!

I’m not from the US. Is it really his choice? I thought it would be more democratic and the party members would vote for who they run, how they run, etc?

Great! Gojira is my favorite environmentalist metal band! Love their often interesting rhythmic choices and their atmospheric sounds.

It propably grabbed the info off some random number-confusing dude like me, who recently posted the Earth’s diameter would be about 6 km instead of 6000.

Edit: oops, did it again. Meant radius, not diameter…

Eau de Paris’ data shows that pollution levels in the river exceeded regulatory standards on most days between July 26, the start date of the Olympics, and Wednesday. Eau de Paris did not release data for Thursday and Friday, when the men’s and women’s 10 kilometer swims were held.

Lol, do they try the Covid strategy of “no numbers, no problem!”?
