This article talks about weight gain across species, in different environments.  It's not just humans: everything seems to be getting fatter.  Some ideas are suggested as causes, but little is know for sure except this is happening.  Even lab animals in highly controlled conditions are getting fatter.  :/

Salt Intake

... has a fairly narrow range, not greatly affected by diet.

I'd be happy if restaurants quit over-salting their food, because I've had some bad experiences with it.  I can't eat things that are too salty; it makes me desperately thirsty until the excess gets flushed out. >_<  Conversely, it takes very little to run down the supply.  When I work outside in warm weather, that little bit of sweating is enough to make me want salt.  I'll come indoors, eat 3 potato chips, and be fine.  Based on my observations of other people, I thought my range was much narrower, but maybe it's not that far off and other people are just less alert to their range.

Anyhow, efforts to minimize sodium in the body by manipulating diet are unlikely to work, as it is not controlled by diet but instead by biochemistry.  I would say, try to avoid excessive  salt, but don't try to force it down artificially low.  Even with excessive salt, it won't stay put -- the body flushes it out.  The documented range is really quite stable.

Child abuse is 40 times more likely when single parents find new partners.

Children living in homes with unrelated adults are nearly 50 times as likely to die of inflicted injuries as children living with two biological parents.


Obviously, doing something that raises your child's risk of maltreatment or death is abusive.  But it is not reasonable to order adults to refrain from leaving bad relationships or to abstain from sex/romance after leaving.  I also don't think it's going to be very effective just expecting people to ignore a very potent if subliminal evolutionary drive -- it's quite common for animals to injure or kill unrelated offspring.  If that would work, we wouldn't be seeing these astronomical increases.  

I think the best solution is to build better relationships in the first place.  That is, return to serious courtship.  If you want to screw around, that's fine, but don't make babies while doing it.  First find a partner, then get married and make a home, then have kids.  Today, people often do it backwards.  That's not a great way to make a life, and apparently it's a great deal more dangerous to the kids than expected, beyond the usual heartbreak, upheaval, financial wreckage, and lost fault tolerance.  If people put in the effort to make solid relationships first, that would greatly reduce the number of kids living with unrelated adults, and thus lower the risks.

Yeti Bear?

This article suggests that the yeti may be an unknown species of bear.  As some bears stand erect and even walk a few steps, it is plausible to consider a species that does so more often.  Certainly a bipedal stance would be one way to deal with the snow and to reach food overhead.  Another interesting fact is that some species cope with cold weather by adapting a more compact form, such as shorter muzzle, ears, tail, etc.  That could make its face look more apelike even if it is not a primate.  Bears are also pretty smart, and while some are pugnacious, others are really shy and hard to find.  It's not hard to imagine one with the social tolerance of a snow leopard.

 Older brains may respond slower not because they are declining but because they have a a much larger database to search.  This reveals severe flaws in the cognitive testing array.  I would like to see a test for accuracy added, because a larger database should -- if healthy -- do a better job of solving problems than a smaller one.

Today I found this article about climate change causing an increase in kidney stones, which become more frequent as temperatures rise.

That reminded me of a previous article I read about climate change causing chronic kidney failure.  Normally dehydration is an acute problem, easily fixed by rehydration.  But the higher the temperature gets, the harder it becomes to stay hydrated.  If people work hard in high temperatures, eventually that starts destroying their kidneys.  Previously healthy people with none of the usual factors for kidney disease develop kidney failure over a few months, and often die because they can't get treatment.

So there you have it: climate change kills kidneys.  Since all humans have kidneys and need them to survive, that poses a threat to everyone.  It will hit the hardest workers first, and it is already an epidemic in the hottest parts of world, which will spread poleward as the climate cooks off.

Things you can do:

* Avoid high temperatures, and especially, working hard when it is very hot.  If you must work outside, consider the siesta pattern: work in the morning and evening when it is cooler, resting during the hot midday.

* Drink until you slosh, and if you sweat a lot, choose a beverage that replenishes electrolytes too.  Avoid dehydrating drinks such as alcohol or soda.

* If you have to work in the heat, especially if you can't keep up with water loss, keep a close eye on your kidney health.  Ideally, tell your health provider about your concerns and figure out a tracking plan.  Catching this stuff early can mean the difference between life and death.

* Know the symptoms for kidney stones and kidney disease.  Also learn about heat stress.

* Most crucially, remember that heat stress and dehydration are typically acute problems that are quickly fixable with lots of water and cooling off.  If that does not work,  then you have an emergency which requires expert care.  Then you have to avoid that situation again, or it's quite likely to kill you just like it's killing people around the equator.

 I've said this myself, but this rendition is nearly liturgical in its elegance.  Look at the lovely parallels.  Such a graceful way of saying, "Bend over and kiss your ass goodbye."

 These microrobots are all identical, but they come together to form aggregates that can do various things.

Yes, they are related to nanobots.  Might could be people should put more effort into developing ethics.  But microrobots aren't as powerful as nanobots; they're big and clunky.

At this scale, variable modular robots tend to be more powerful.  Frex, Cubelets are blocks that perform a function.  Stick them together to make robots.  Think of these like organs in a body.  Because they can do different things, they are useful; because they can be connected in many ways, they are versatile.

Dancing is a bonding activity that makes people feel good and enhances connections.

Most cultures have their own dances, although the importance of dancing varies from one culture to another.  Modern America values it very little.  We used to have lots of dances at all kinds of social occasions, and almost everybody danced themselves instead of sitting around watching other people  dance.  What little we have left is not structured and cohesive dancing; most of it is individual freestyle club dancing.  This shift correlates with people being less fit and feeling less connected today -- really not a good change.  >_<

So watch for opportunities to dance.  If you coordinate events, look for a way to incorporate dancing.  It doesn't have to be fancy, just frisky.  It helps to include a basic lesson in whatever dance you offer so that novices can join the fun.  Pay attention to local culture and feature dances that match your audience.  Ballroom dance, African folk dance, European folk dance, Latin dance, belly dance, break dance, hoop dance, etc. will all appeal to different folks.
