How much bandwidth does the spinal cord have?

Posted: 20 Dec 2017 03:01 PM PST

I was having an EMG test today and started talking with the neurologist about nerves and their capacity to transmit signals. I asked him what a nerve's rest period was before it can signal again, and if a nerve can handle more than one signal simultaneously. He told me that most nerves can handle many signals in both directions each way, depending on how many were bundled together.

This got me thinking, given some rough parameters on the speed of signal and how many times the nerve can fire in a second, can the bandwidth of the spinal cord be calculated and expressed as Mb/s?

What would happen if your brain floated in water instead of cerebrospinal fluid?

Posted: 20 Dec 2017 06:27 PM PST

I think it's safe to say we wouldn't be able to function as humans, since the CFS apparently provides some pretty vital functions like protecting the brain against blood pressure spikes. That's the extent of what I know though, so can anyone tell me exactly what would happen if all the CFS in our skulls were suddenly replaced with pure, distilled water?

If you put a live power cable in the sea, how far away could it electrocute someone?

Posted: 20 Dec 2017 12:36 PM PST

What got me thinking about this in general was wondering about my house flooding and whether or not the electricity box becoming compromised with water could cause all of the water to become electrified.

Also, I remember a scene from Ozark, the Netflix show starring Jason Bateman, where something similar to my original question happened in a large body of water.

Can sea creatures be invasive?

Posted: 20 Dec 2017 07:38 PM PST

As we all probably know there are many instances of animals being introduced to a new environment and having no natural predators and become a problem. I know this can also happen with fish too in lakes and rivers. My question is can this happen in the ocean since one way or another all the ocean is connected.

Why Does The LHC Reach Such High Temperatures?

Posted: 20 Dec 2017 06:42 PM PST

I saw on reddit that one of the highest temperatures we know of in the universe was created at the LHC. I don't know a ton about the LHC other than it smashes particles together, but wanted to ask what causes it to reach such high temperatures?

I think I read somewhere that some of the experiments turn matter into energy, is that what causes it?

Thanks!

Other than Neanderthals, did humans live alongside any other homo species?

Why do some medicine need to be taken on a full stomach/with food where as for others it doesn't make a difference??

Can drinking alcohol prevent food poisoning?

Posted: 20 Dec 2017 03:31 PM PST

Alcohol can be used as disinfectant, so if you had some food that was just starting to go bad, or perhaps had some mold or was past it's expiration date, would drinking liquor with the meal kill the bacteria that makes you sick? What about wine or beer? Is there a certain proof needed to kill bacteria, and does it only affect certain types of food related illness?

Does anyone know any specific species that are affected by the cicadas' 13 or 17 year cycle?

Theoretically, is it possible to create an atom big enough with enough protons, neutrons, and electrons to be observable with the naked human eye?

Posted: 20 Dec 2017 11:29 AM PST

Even if it was for a fraction of second, is it feasibly possible? Or is there a limit to how big an atom can be?

What causes LA (local anesthetic) resistance?

Posted: 20 Dec 2017 09:36 AM PST

One of my molars needed a cavity filled, so the dentist did the typical cotton swab followed by injection of Lidocaine. 5 minutes later, he came back and tried to drill into it. Know that pain you get when you have a cavity and bite in to either something very cold or very sugary? It was like that, but 10x. He gave me another shot of Lidocaine and tried again 5 minutes later. The same pain, if a little bit less. He had to do a nerve block shot, and even then I could feel it a little bit. Did a bit of reading about anesthetic resistance and apparently this subject has not been extensively researched.

Does anyone else here have experience with this or has studied it? Apparently it's only a very small amount of population that has this resistance, I'm just glad that I'm not completely resistant. How does it work and why has it not been thoroughly studied?

Does milk spoil inside of female mammals?

Posted: 20 Dec 2017 09:52 AM PST

If a female, let's say cow, isn't milked for a while, does her milk spoil in the same way milk spoils if left out in a similarly temperatured container?

Is there such a thing as geometrical body that has the MAXIMUM area for a given volume?

Posted: 20 Dec 2017 07:31 AM PST

In 3D space, a sphere is the geometrical body that has the minimum area for a given volume. Is there such a thing as an...uh..anti-sphere?

How does our brains look for stored information?

Posted: 20 Dec 2017 10:54 AM PST

So I saw a picture of Tom Cruise and wanted to google him. But I couldn't remember his name, I knew that I know what's his name is but at the moment it didn't come to me. Nicolas Cage, no, Brad Pitt, none of them fit. Then I thought; he's a scientologist which made me think of Jon Travolta but thats the other guy.. Suddenly I remembered southpark and the word closet and then the quote "Tom Cruise wont come out of the closet" and boom I had his name. But how does this all work?

What is the effect on the size and density of the atmosphere and its effect on flight? Planet mass is 1.030843538230884704452608 × 1025 kg and the size is 8.292 * 106 km.

What makes whole genome sequencing so difficult?

Posted: 20 Dec 2017 07:50 AM PST

Recently I've been reading into the topic, and discovered the human genome has never been completely sequenced.

I understand that parts of the genome that are very repetitive are harder to piece back together, but why is it difficult to read long chunks at a time?

Thanks!

P.S. If you know of any books or other resources on the modern challenges to whole genome sequencing, please point me in the right direction!
