Scientific Mash Up #2
Welcome to the second volume of trumpman's scientific mash up. As a reminder, this is a reccuring compilation of various interesting scientific stuff I come across.
Enjoy:
The Optimal Number of Steps for a Long Life
Chances are you have heard how we must take at least 10.000 steps a day to live a long and healthy life.
That is the equivalent of about 8 km. Ok, not huge, but depending on your lifestyle it might not be achievable, especially if you have a sitting job.
But does the myth stand true?
Well, I stumbled this really cool meta analysis today showing how this piece of conventional wisdom isn't far from the truth, at least for young adults. But as you age more and more, less and less steps are required.
Tldr, 8000 steps are more than enough in most cases for optimal results. Sure, the more the better, but for whatever reason, benefits seemed to plateau after that number.
In this meta-analysis of 15 studies, seven published and eight unpublished, we found that taking more steps per day was associated with progressively lower mortality risk, with the risk plateauing for older adults (aged ≥60 years) at approximately 6000–8000 steps per day and for younger adults (aged <60 years) at approximately 8000–10 000 steps per day. We found inconsistent evidence that step intensity had an association with mortality beyond total volume of steps. sauce
Dose-response association between steps per day and all-cause mortality, by age group
So yeah, 10k of steps is a good number to go for, but 8k seem to be more than enough
Did someone say sustainable fishing?
This is a really worrisome paper, at least when it comes to shark populations. You have probably heard the term sustainable fishing, blah blah blah, regulations and bullshit like that.
So, this newly published paper on Science revealed that despite all the new regulations and shit, global shark mortality continues to go up:
Here we estimate that total fishing mortality increased from at least 76 to 80 million sharks between 2012 and 2019, ~25 million of which were threatened species.
And honestly what annoys me the most is that a good chunk of them die a slow death because some idiot somewhere wants to drink fin-tea or some other bs that will make their dick harder. At least eat the whole fucking thing instead of throwing the rest of the shark back to the sea. What a waste.
Oh well, massacring the pex predators of the seas...What could go wrong, right? Well, to be fair we massacre pretty much everything so maybe one negates the other 😅
Amazon's Ancient Agricultural Civilization Unveiled by Lidar Technology
I love it when archaeologists discover something totally new. And this is one of those stories!
Archaeologists using lidar technology have discovered a hidden pre-Hispanic civilization in the Amazon rainforest, that seems to date all the way back to 2.500 years.
The ruins were discovered Upano Valley site, nestled in the eastern Andes, and they seem to belong to an advanced agricultural civilization, the earliest and largest that we know of in the area.
The research revealed over 6,000 rectangular earthen platforms, plaza structures, and interconnected roadways spanning an area of approximately 230 square miles (600 square kilometers
The most notable landscape feature is the complex road system extending over tens of kilometers, connecting the different urban centers, thus creating a regional-scale network. Such extensive early development in the Upper Amazon is comparable to similar Maya urban systems recently highlighted in Mexico and Guatemala.
One can only imagine all the kinds of artifacts and treasures that will be unearthed when (and if) they actually start digging!
Ok friends, this is it for today. Feel free to click any of the links above to read more on the stories that I have shared!
See you soon with more sciency stuff!

I thought the more we grow, the more steps a person should take a day is a good thing.
This seems interesting, I noticed when I was in my hometown - village that's where i was taking like 10,000 steps a day or more
But in city I'm spending more time in home... Can tell I barely made 1000 steps today. Probably one reason why people have more mortality rate who're living in rural areas...
this is hilarious and true..
It's surprising seeing archeologist discovering civilization till now... Will be interesting what they'll find there once they dig.
Sadly, it will take a while. These excavation usually last decades, and that's supposing there is enough funding 😞
You can prove anything with a good statistician... Never trust a study without reading the nitty gritty details!
It's great that they continue to find ancient ruins throughout the continent of South America. People there were far more advanced than they are given credit.
I'd love to have a time machine, it would be fun checking all those unknown ancient cultures!
There is no such thing as sustainable fishing. Words that bureaucrats use to sustain there selfish ways of keeping there pockets fat. Pollution frome economic activities is among the top killers of marine life,
Yeah, won't disagree. One ecosystem going down after the other, wonder how much more beating mother earth can take 😞
Dam I usually have that amount of steps by noon every day. Nice, I’ll live to be 100.
It’s those fucking horny Asians… they are to blame.
Wow that’s freaking cool. The Amazon is no joke to try and dig though. It might take decades.
Keep walking old man!
Yupp it all takes a time. A time of good opportunity a time of good work
It's an interesting study but more steps tends to mean you are exercising more to an extent so I think it makes sense.
As for sharks, I don't really go out to sea and I have never tried shark fin soup. So I guess there are always people out there who want stuff.
Old ruins sounds nice. I hope they are able to find some interesting stuff out there.
10k steps a day not achievable for some? come on ... I doubt cars are essential for human life :P
I wish all those who kill the sharks (especially those who kill them slowly and painfully by cutting their fins off and throwing them back to the sea) would once find themselves facing the sharks without their boats, technologies, harpoons etc. That would be a fight I would enjoy watching. In my book, humans are the worst species on Earth.

Yeah, it really really really bugs me. These fuckers deserve the worst of deaths. The least you can do is respect the death of the creature and eat the whole damn thing.
In the same way, the big fish should not be killed because we see that their numbers are decreasing now, if they continue to be hunted in this way, they will disappear one day.
