So, I'm not usually one for conspiracy theories but this really reminds me of something I read not too long ago:

1. and 2. - previous comments on Reddit by a user who noticed similar activity and: 3. - a Guardian.co.uk article on the subject.

Can someone help me out - the only thing I can find while searching is the second post credits scene (this video) but I can't find anything about the first one.

What takes place in the first post credits scene?

Fuck no. I like the internet too much. Also functioning grocery stores with fresh (and perishable) foods, creature comforts, electricity / heat / water utilities, etc...

I just did some very basic research on Mederma. From what I'm reading it's supposed to improve collagen organization after an injury - or at least a study showed it did so in rabbits. The process of remodeling does this over time, to some extent. The better organized the collagen of the scar is with relation to the surrounding tissues the more similar the scar tissue is to that surrounding tissue (meaning it looks less like a scar and more like normal skin).

If this product actually does this then I can see it reducing scar visibility. From the wiki article though the only study that showed improved effect (compared to the use of petrolatum emollient) was the study funded by the Merz pharmaceutical group - and they want to sell their products so I wouldn't consider them a non-biased source - that kind of thing is always an issue when evaluating research and testing.

Paramedic student here, we just went through this topic in soft-tissue trauma.

Short answer is that your skin goes through a process called 'remodeling' in which the tissues of your skin are rebuilt in the area of a wound. This process replaces the tissues in the wound, but not in exactly the same way as the rest of your skin. After that, the normal replacement cycle of cells that go on maintain whatever form or shape the tissue forms into (for the most part). Non-short answer below.

So, at least for this type of trauma, there are five stages in the process of wound healing that occur: Hemostasis, Inflammation, Epithelialization, Neovascularization and Collagen Synthesis.

Hemostasis: this is your body stopping the loss of blood directly after an insult, in this case let's use a laceration as an example. Blood vessels constrict, larger (severed) vessels pull back into tissue, the disrupted tunica intima of the blood vessels exposes collagen and other proteins to blood - this activates a series of enzyme reactions that alter certain blood proteins into fibrin strands which then trap RBCs and start to form a sticky semi-solid mass. This is the beginning of coagulation.

Inflammation: The inflammatory response is triggered by the injury. Chemotactic factors released by damaged cells attract WBCs (granulocytes & macrophages at first) to the area - these attack and clean up foreign bodies they find (bacteria and such that was introduced by the break in skin). The damaged cells, the concentration of WBCs, various proteins and cellular byproducts at the wound site cause mast cells to release histamine. Histamine increases fluid delivery to the area and that fluid brings more of everything the body is using to repair the damaged area. Edema (swelling) occurs.

Epithelialization: Epithelial cells migrate to the wound surface. The stratum germinativum cells divide and regenerate very rapidly to restore a layer of skin cells along the edges of the healing wound. Here's where the relevant part about scars start. Unless the wound is minor and/or superficial, the new epithelial layer is not identical to the original skin. The new skin layer can be thinner, differently pigmented and lack hair follicles. If the wound is large enough this process can be incomplete and collagen shows through as shiny pink tissue (a scar).

Neovascularization: New capillaries grow in the effected area to be able to properly perfuse the affected area.

Collagen Synthesis: Collagen is the main structural protein in the body. Fibroblasts travel to the wound area and synthesize collagen - this binds the wound together. The healing wound is not "as good as new". This regenerated skin has about 60% of the strength of undamaged skin (at 4 months when the scar is mature). The wound may re-open to small or large extents from stretching or lesser impacts or other trauma. Fibroblasts keep reshaping the scar tissue and shrink the affected area for months after the scab is gone - this is the process of remodeling and can go on for up to a year.

I have a 4Sevens Quark 123² Tactical for a while now and love the thing. Excellent performance curve - 30 days on time with the moonlight setting (0.2 lumens) and the (now outdated) model I have goes to 190 lumens max.

The X series now goes to 380 lumens I think but are all out of stock.

Not where I am. Perhaps some states have that as a law, I wouldn't be surprised, but none that I specifically know of.

Anyone can tell you to leave their home because you have a gun (or for any reason, or no reason - it's their home), but if they haven't told you to leave then there isn't an issue. The only other possible legal preventative measure would be if they put "no gun zone" or equivalent stickers on their doors or otherwise made it clear that firearms were not welcome in their premises.

We have this technology in use in the medical field for the production of high-percentage oxygen. Hydroxide compounds are used to chemically bond to the carbon and let O2 pass through - sodium hydroxide, lithium hydroxide, calcium hydroxide - all are used for CO2 scrubbing - but they will eventually get saturated and stop working unless either replaced or treated to cause the chemicals to release their stored carbon content.

In terms of oxygen production (or rather, CO2 -> O2 conversion) in a space setting we generally go with a large enough store of these chemicals in replaceable modules. For a closed cycle? Even the ISS isn't truly closed-cycle, they still use consumables that need to be replenished. Here's how the ISS does it. If you wanted truly closed cycle you would probably need a large area for hydroponics. I don't know of any non-plant system that can truly create a closed-cycle that requires only energy and no outside resupply.

It depends how far along you want to go to define the 'end cause' of death. If you go far enough I can't think of any cause of death that does not come down to inadequate tissue perfusion. If you step up from that it is just a matter of describing the specific cause of inadequate tissue perfusion at a case-by-case basis.

Going up a level and specifically to explosions? Airway compromise (from blast or shrapnel damage or facial burns...), hypotension (from internal or external hemorrhage or severe plasma loss from burns or perhaps neurogenic shock causing severe vasodilation leading to severe hypotension), and tension pneumothorax (which is separate from airway compromise in that it isn't exactly part of the airway but rather a compromise of one or multiple functions of the thoracic cavity - most commonly being either compressing a lung to the point at which it cannot ventilate or compressing the heart to the point that pumping action is no longer adequate to sustain life).

There are other causes, such as the secondary cause of septic shock resulting from infection due to the loss of the protective functions of the skin secondary to large-area burns (or sometimes even smaller burns).

A traumatic insult directly to the brain might be considered separate from the 'hypotension' cause depending on how you define death (if someone is brain dead but still has a heartbeat and a respiratory drive...). If there is an insult directly to the brainstem region and there is no more respiratory drive then that leads to hypoxia which leads to inadequate tissue perfusion of the myocardium which leads to the loss of effective pumping action of the heart and so on.

...

Ok, final cause of death from being burned to death? Hmm. If the person survives the initial burns then usually either hypotension from severe plasma loss or septic shock from secondary infection. If the person dies in a fire? Usually either hypoxia from breathing toxic smoke laden air which also has low O2 levels, sometimes just the carbon monoxide content does it. Airway compromise due to airway burning would be the other common cause. Even if someone got completely burned to bones and ash they probably died of one of those two causes before their body actually burned.

According to my professor from Human Sexuality (perhaps a year or two ago) sex produces part of the chemical base for emotional bonding with, among other chemicals / hormones: Oxytocin and Phenylethlyamine.

From what I understand about his view on the chemical and hormonal underpinnings of bonding emotions, sex only lastingly contributes to these feelings (in general / on average) if the couple in question continues to have regular sex (say 2-3 times per week or more).

Standard disclaimer about everyone's individual neurochemistry being different of course.

As to your question of how to deal with it: how do you want to deal with it, or rather, how do you want to feel about him? Are you ok with how you feel (you mentioned that you've "tried to get it on over the years") or do you want this change in your emotions towards him to stop? Is it more that the sudden change is freaking you out?

I came here to advise looking for this car specifically. Excellent fuel economy, above 50mpg if you know how to drive for it and keep the vehicle maintained. Engine can last 300-400K miles or so - just all around an economical vehicle. The price of diesel doesn't figure into it much when you can literally go twice as far for the same amount of fuel as an average gasoline vehicle.

I've been looking for one and have found many for $5K and under that are in good mechanical shape. The only reason I don't have one yet is that I've been hoping to find one for... much less than $5K. This has been difficult. Searchtempest has been a useful resource.

There are a bunch of unspecified variables here that would effect the outcome.

Initial hydration of the subject?

Subject at total rest, operating only at basal metabolic rate? Exerting themselves significantly & sweating profusely? Sweating would remove some of the fluid volume before the kidneys had to process it.

With or without electrolyte (primarily sodium, but others too) replacement? You can die of hyponatremia by pulling too much sodium out of your system (specifically the sodium that your cardiac muscle uses in the Na-K pumps).

Going with the above variable, initial electrolyte levels of the subject?

For that matter, are we looking for how much water this subject could consume in a 24 hour period without feeling ill-effects? With problematic symptoms but still alive? How much the subject could consume before death?

Environmental temperature the subject is exposed to?

So, lots of affecting factors here. The most you could hope for, even with said variables defined, isn't an exact amount but rather a range of volumes (between X and Y liters). Perhaps it would be possible to get a narrower range for a single test subject, or rather not a range but something more like a multivariable affected graph or plot.

Ok, I'm back from class. Still on track for the goals I set out for myself. Close to done with Paramedic class and consistently at or near the top of my class - it's a lot of fun. After that I'll save up for the Medic-to-RN program and as an RN I'll be able to fund... some of the more expensive goals I have.

Maybe I'll do a followup IAMA after medic class.

Used to collect baseball cards a long long time ago. Still have them all, probably around 100,000 cards and tons of unopened packs from the 80's and 90's. I'll get around to selling them sometime.
