      UPDATED: MESSAGE BOARDS CLOSING AFTER DRAFT   03/08/2017

      After careful consideration, we have decided that we will sunset our message boards after this year's NFL Draft. Since we opened our boards a decade ago, the digital landscape has greatly evolved. While we understand there remains a smaller group of highly-engaged fans who participate in conversation in our forums, a significant amount of the dialogue about our team and our games has migrated away to other social media platforms over the past several years. Our message boards will remain up and running through Friday, May 5th, and will be removed on May 6th. We recognize that this change may upset avid members of our community. However, we look to utilize our time and resources to focus on how we can best connect with our fans across an array of digital/social outlets. If you are not already engaging us and other members of the Ravens Flock on our Facebook page, Instagram account, through Twitter or Snapchat, we invite you to follow us on those channels and continue to participate in our social communities. In addition, the commenting feature on our website articles will remain intact. Members will be able to continue using their boards account to log in and share their thoughts at the bottom of every news story. We’d like to thank all the Flock members and our moderators who have brought thoughtful conversation to this space and made our community great for the last 10 years. Ravens Social Media Hub »

How do you make nitroglycerin? lol

In a lab with the right experience. 

Seriously, this isn't something you'd do at home, even if you knew how. the conditions are very specific and difficult to maintain without the necessary equipment.

Has the relative lack of natural selection and proliferation of recessive genes doomed the human race?

Also, are autoimmune diseases caused and/or exacerbated by excessive vaccinations and antibodies? 

Also could it be possible to develop a preventative Tommy John type surgery to prevent knee injuries?

I'll break this down into two parts. I can't answer about natural selection currently because we will not see it in our lifetime. 100,000 years would be considered very short for the time of natural selection. We're talking about a process that takes generally millions of years. As for recessive genes, they aren't inherrantly bad whatsoever. For example, Huntington's Disease is actually dominant. Plus, there's a hierarchy in some cases. A gene can be dominant when compared to gene B, but recessive to gene C. So the answer I'm going to give is no.

This is a recent theory that isn't very likely to happen whatsoever, but we'd need their to be "molecular mimicry". That is to say the foreign and self peptide need to be so structurally similar, nearly homologous, to the point that your T Cells cannot differentiate. if there was even a remote chance of this happening, it'd be picked out and warned about during field studies. Further, when you receieve a vaccine, your levels of cytokinase, a very important molecule in cell signaling, is lower than when you get the actual disease. Basically, T Cells are less likely to be reactivated AFTER a vaccine. Does that mean it can't happen? No, it could, but the chances are negligent, vaccine or real disease both being taken into account.

As for the last one, I doubt it. With Tommy John surgery, the UCL is just a really flimsy ligament. You could introduce a stronger fiber into the body, but you'd risk the chances or chipping the bone or shred off pieces.

Great post BmoreBird22! 

Would it be possible/beneficial to gain all your nutritional requirements through an IV drip? say say while you're asleep, kind of like an intermittent fasting timeframe but without the actual downtime required for digestion.

Also does dehydration lead to an increased level of waste byproducts building up in the body? is there a long term benefit to maintaining ideal hydration 24 hours a day compared to say intermittent levels of mostly high hydration with short periods of dehydration?

Thanks in advance.

Hot is this possible without burning your feet? 

And eat fire without burning your mouth? 

https://youtu.be/H_8PRUcrXlk

 

I can actually tell you about the first one. 

I didn't watch the video, but assuming they continuously walk, there's just not enough contact time for the coals to sear the foot. It actually remains warm, but not burning hot if you just keep moving your feet.

I would have to say that no, it would not be helpful. In fact, it could be fairly dangerous. By using an IV, you're probably going to use a saline solution (salt water) solution to dissolve it, so you have to use water soluble vitamins to actually dissolve inside the IV. Water soluble vitamins aren't stored in your body past the needed amounts, so your body will just urinate them out. However, assuming your body DID take in more than needed, you'd run into possible issues like racing heart and flushed feeling (niacin) or something more severe like kidney stones (vitamin C). 

If you could dissolve and take in fat soluble vitamins by IV, you'd run into a different issue. Your body actually does store those in your body fat and tissue. You have a higher tolerance to fat soluble than you would water soluble, but same thing applies that it can lead to things like liver disease.

This is of course just the example of vitamins, but you'd run into the same issue for something like iron (which can cause diabetes). Generally, those necessary vitamins or nutrients have a safe limit for intake and it's best not to consume them. So, assuming you used the IV to get literally all you needed and nothing else, you wouldn't be eating for the rest of the day. It's probably a lot easier to just take the pills if you're having issues with low nutrients.

If I'm reading the question correctly, the answer is no, it won't make your body produce more waste. However, not being hydrated CAN have a big impact on your body's ability to actually rid itself of waste. Your kidney's especially rely on water as a transport for waste out of the body. The number one waste leaving in your urine is called urea, a nitrogen based compound, along with some other water soluble wastes. However, urea is the reason why your urine is yellow. Really dark and super yellow urine means your body didn't have enough water to use as a transport medium and the kidneys kept in the water to help with normal functions. For your GI, if your body doesn't have enough water, it gets pulled out of your stool and that's what leads to constipation. 

However, keep in mind that there can be TOO MUCH water in the body. Your cells have an ion pump that maintains an ion gradient in cells and the surrounding fluids by pumping out sodium and pumping in potassium. This helps give the cells their charge (a negative charge of usually around ~(-70)mV). The reason this is important is that the negative charge gives the cell a "battery" ability to conduct its own cellular function, but also allows a charge to run through in muscle and nerve cells when they need to conduct a charge. Too much water will cause an uneven concentration gradient and the cell will begin to release ions and begin to lose its charge and then it can't carry out its normal function.

As far as an optimal period of hydration/dehydration, I don't have an answer. I'm going to say it's probably better to continuously hydrate yourself throughout the day without overloading at any given time.

We do that, actually, in the hospital for people with digestive issues like colitis or bowel obstructions that can't be resolved quickly. It's an inexact science requiring constant monitoring (lots of blood draws, needle sticks) and a pretty high risk of infection at the IV site (nutrient rich solution provides an excellent medium for bacterial growth). Also,  the solution is pretty caustic to the veins going in, and can cause phlebitis and other localized reactions. So, not recommended outside of life-threatening conditions. 

As for #2, SEVERE dehydration can lead to kidney failure (poor perfusion to the kidneys can cause them to die), but Bird is right - the body is designed to maintain fluid balance despite fluctuations in oral intake. Think of your GI tract as a holding tank,  you fill it up, then your body takes what it needs as it needs it, and flushes what it doesn't need out the kidneys. You don't actually go through cycles of overhydration/dehydration just because the levels in your tank go up or down.  You just need to remember to fill it up occasionally. 

On a side note,  alcohol depresses the part of your brain that tells your kidneys to conserve water, which is why the floodgates open and you have to pee so much when you drink, and wake up hungover with cottonmouth. The more beer you drink, the thirstier you get, so you drink more beer,  which actually dehydrates you even more. That's why they recommend balancing each alcoholic drink with a glass of water,  and drinking a huge glass of water before going to bed. Keep that tank full,  your body will thank you in the morning.

I'm gonna give you the laymans terms. Water helps constipation. Any sorts of constipation without getting into specifcs

I dont remember if i posted anything about this, but here is some quick info about the Mars One mission.  Obviously funding is an issue, i dont see why Mars One and SpaceX, Elon Musk's space company dont come together, seems logical.  Im really excited to see where this goes

Sidenote, i know the narrator of the video is odd and the channel is kind of corny, but i get hooked on his videos, some are awesome.

Who watched this show? I find it fascinating. But there are still questions before going there. Space Ex has the right idea but it can go to mars but cant return home. Why cant Space Ex build a shuttle does the same thing that rocket does takes off and land at same time. Look what the Space Ex rocket does

A meteorite recently slammed into Mars and left this giant black stain of a crater

 

(An illustration of Mars against the blackness of space.NASA/JPL-Caltech; Dave Mosher/Business Insider) 

Like Earth, planet Mars is a shooting gallery for rogue space rocks that zip around at tens of thousands of miles per hour.

But the red planet has barely 1% of the atmosphere of Earth's to slow down, vaporize, and break up any of these stray lumps of stone and metal.

It also lacks the flowing surface water and robust weather of our home planet to quickly erase signs of the impact craters these strays leave behind.

As a result, Mars is littered with celestial pockmarks and, occasionally, researchers spot fresh impact craters using orbiting satellites like the Mars Reconnaissance Orbiter and its HiRISE camera.

Studying fresh impacts not only helps researchers peek at freshly exposed dirt on Mars, which may have once been habitable, but also helps assess how much risk Earth might face from small yet dangerous space rocks.

Below is a zoomed-out image of one asteroid strike that was photographed just a few months ago, and it shows the giant black stain the event left behind:

Oh my,,, What would have happened if that meteorite slammed into earth? runforhills.gif

Extraordinary moment enormous alligator strolls past tourists in Florida

 

Stunned tourists have captured the moment a huge alligator strolled past visitors at a nature reserve in Florida.

Footage shows the enormous creature – thought to be about 12ft long – looking relaxed as it walked past families at the reserve in Lakeland.

The reptile ignored awe-struck visitors who stood filming him just metres away.

According to the Polk Nature Discovery Centre Facebook group, the alligator’s name is Humpback.

Kim Joiner, who shared the video, described it as “nature at its best”.
