Saturated va unsaturated fat is basically about whether that particular fat is a solid or a liquid at room temp. There are multiple varieties with saturated generally being less healthy because it raises the "bad" cholesterol. They don't change from one to the other with temperature, though some can change with chemical alteration.

Trans fats in cooking MOSTLY come from plant based fats that have been altered to be solid at room temp, like saturated fats. They do occur naturally in small quantities in some meats. They are cheap, shelf stable and for awhile it was thought the plant based fats might be healthier than animal based frying fats all of which made them appeal for fast food frying and such. Turns out they hit that "bad" cholesterol (LDL) worse than even natural saturated fats.

Cooking oils and other things to fry in are basically just pure fat. That makes them VERY calorific and if your fried food picks up much of any of it it will have more calories in turn. Carbs also crisp nicely when fried so you tend to see a lot of added breading in fried foods or frying of inherently starchy things like breads and potatoes which are already pretty calorific to start with.

Well...yes. Because if intervening factors occur you're measuring the probability it will happen over the span of time until that intervention occurs, not infinite time.

Basically any time you start hearing "infinite" thrown around you're probably in a purely theoretical scenario with a conspicuous lack of limits or z-factors.

They'll put all of a product on sale if the stock is expiring soon but i haven't seen a clearance rack for individual items like the bakery section does.

I worked at a rural wal mart unloading trucks. We averaged 3 trucks of GM and two fridge trucks on the grocery side per day.

What do you think the ones in town are doing?

They roll that stock constantly. Retail runs on very tight margins and they have logistics down to a quite literal science.

That's usually a- and an- like a-theist vs an-esthesia.

A- and an- are greek rooted and mean "not" as in a total nonexistence or rejection of. Like an atheist believes in zero gods.

Ab- is from latin and means away from, but still existing. Like... absent doesn't mean you don't exist, you're just away from here, absorb means to draw something away from where it is now not to destroy it, etc...


azuth89 t1_ja57r6v wrote

Abnormal is more normal in this sense, oddly enough.

"Ab" as a word of its own means from, but ab-the prefix usually means "away from" for whatever reason.

So...abnormal = away from normal. Perfectly sensible.

Ab origines, as two words, means from the beginning. Okay, that tracks.

Aborigines, one word, should mean away from the origin/beginning. Wait...what? It's like we lost the space over the years and because latin is stupid and arbitrary sometimes should have inverted the meaning but we kept using it.

Most old headlamps are 35w or 55w, which means you'll want at least a 5 amp 12vdc supply. You can google for that phrase. If you want to go with a smaller, cheaper supply you can slot in a lower power or LED bulb.

I...might downgrade the bulb for display anyway since a roadworthy headlight, even the old ones, is really bright to have sitting aorund inside.

Yes, it is in many ways different than ours but they have bacteria on an in them that helps crowd out more harnful organisms and process nutrients, many famously have very tight connections with fungi in their root systems to ferry nutrients and even signals arouns, things along those lines. They also have common but non lethal parasites just like animals in addition to .ore destructive ones.

The details vary with what kind of plant you're talking about.

A huge number of people put massive stock in graphics. For that group, playing something they already liked with better graphics is a fantasy come true.

A second group that helps make these popular is the crowd that didn't get started gaming early enough to catch the first release or even own consoles that can easily play them. For that crew they're seeing a good game for the first time and...yeah, of course they like it. Deadspace is a great example, there are a BIG chunk of gamers out there that weren't able to play a horror game 13 years ago and it's a legend, of course there would be interest in getting to play it now across teens, 20-somethings and older folks who missed it the first time around and the updated graphics just make it all the more appealing.

Mix those together and a fair chunk of people will buy it.

Now, I need to add another item here: Most "professional" video games reviews that are heaping praise on these are done by various media outlets which depend HEAVILY on video game advertisements for their revenue. Whatever the big sales push is from a developer, it's going to be well reviewed by all those outlets. If it isn't, they're not going to keep getting ad revenue for long. It's the same reason car and driver basically virtually never gives a bad test drive review, whatever industry you want to pick.

Right, which they do by combing through existing records and looking for correlation. Covered that.

I didn't say nothing could ever be done or studied, I said controlled experiments are very difficult on multiple levels and they're often leaning on data from other sources. That leaves gaps in what can be studied, but paternal age isn't one of those in many places.

Number of inputs vs lack of ethical control scenarios + difficulty due to time basically.

If, for example, you wanted to answer this question a logical experiment might be to put a bunch of kids in a controlled setting at birth, possibly their mothers if prenatal deficiency is part of the theory, and then raise them for a couple decades with a deficiency in a specific vitamin and see if they have higher rates than the population at large. Potentially do this a number of times to isolate different vitamins, levels of deficiency, timing and so on.

Sound like something you would want to do?

But we can't. So we have to wait for a statistically significant number of people to get diagnosed, hope they have decent medical records and comb through those records for a common thread which stands out from all other possible environmental and genetic influences as a stronger predictor, and then do further analysis to make sure it remains predictive. Maybe start testing a large population in a longitudinal study to see if people with that behavior, deficiency, whatever eventually get diagnosed. Of course, if it IS a vitamin deficiency that wasnt previously tested you have to wrestle with the ethics of whether to address the deficiency or let it go and see what happen when you find it.

Tldr; Anything around brain development and mental health has an astronomical number of variables and few if any ethical ways to create a controlled experiment to start isolating them. Because development takes a couple of decades at least the sheer time and effort involved is also a significant barrier. So instead these studies are often meta-analysis of scattered and inconsistent data generated from other studies.

Less reliable, heavier and harder to use and less immediately effective than more recent designs. Grenadiers were a dedicated unit in some cases just to section off the dudes that were big enough to throw it out of range of their own people, much less carry them around.

They did have some use cases, particularly times when you could drop them into a hatch or strong door instead of having to hurl them yourself, they just weren't widespread like the 20th century.

The BMI definition of "overweight" is pretty tight compared to general American sensibilities. It leaves a lot of room for being cosmetically overweight rather than being a significant health issue and yeah, unusually fit or broadly built people will often be caught in that category as well. It's also just the nature of weight that it's much easier to be over and to be a significant outlier far, FAR over than under. The distribution is right skewed.

That said, North Americans are absolutely majority overweight and have been so long enough that we have a warped perception of weight compared to many places where this is not a decades old issue.

A good example would be to look at modern GMO crops. GMO or otherwise fruit is fruit, veg is veg but they're able to play a bit with size, disease resistance, need for certain nutrients from the environment. They're able to play with size and growth rate within a limit IF the GMO gets the right rnviroent to support it. Lots of little tweaks like that.

Optimization and removing/reducing weaknesses is certainly possible, superpowers involving a whole different body plan like gills or 4 arms, not so much.

The vast majority of our genome is identical. Heck we share 44% of our DNA with a banana, with another person it's nearly 100.

Mapping disparate individuals allows us to try and connect their traits to specific bits of the remaining, variable portions of the genome. It will also help us define what is dictated by genes, what is a genetic propensity which may or may not be activated by environmental factors or behaviors and what is purely environmental.

Once that's done, we can predict a wide variety of factors. Risk factors for various diseases and disorders are of most interest now, but this will inevitably lead to identifying other factors. Once those are identified the inevitable endpoint is editing. First to remove defects like a propensity to say...diabetes, heart failure or even something more minor like myopia but once we start down that road the line between removing risk factors and adding desirable ones is real blurry.

Fully mapping a genome is incredibly labor intensive, but the sample size will increase over time to enable this sort of thing and these initial mappings do a lot to determine what we need to investigate and what can be mostly ignored as the common background to humans.

The really big ones? We could build something large, technologically speaking, but we couldn't boost something like that out of atmo. So we'd have to spend ludicrous resources launching construction equipment to build the construction equipment to build something that large and then boost up all the materials to do so. The cost would be astronomic and then....what? We don't have the propulsion tech to go much of anywhere with it.

If you mean the actual full ship rather than just the size....honestly they're packed with tech we don't have and I'm not sure where to start.

Not particularly. It was just a cult classic that many modders wished to keep playing. Over time running it on random things became a bit of a meme so people just kept running it.

The amount of power available to old games was miniscule compared to modern consumer electronics and many could be "run" the same way.

Some of them are alsobjusr straight jokes involving inserting different hardware into a shell of something, like the pregnancy test one that went around recently.

Honestly I haven't cared much about graphics for like...15 years or so? At least not in terms of model detail, texture resolution, framerate and such. That was all more than good enough for me awhile back. Modern render distances are nice for open world stuff but most people aren't that targeted when they say "graphics"

Stress as in physical stresses. Heavy weightlifting like the other guy said, but you'll also see it from impact like people that get really into martial arts or who swing tools for a living. It tries to build up where you see micro fractures but it can't recover stronger from major damage like true breaks.
