| Are there any major differences in structure and functioning of brains in large organisms? Posted: 01 Jan 2021 06:22 AM PST For example CPUs, GPUs made by humans have vastly different architectures, efficiency and functionality. Did evolution cause similar in brains? Do some organisms have brains that have a completely different way of functioning? [link] [comments]  |
| How to test transmission of COVID-19 after vaccination? Posted: 31 Dec 2020 02:00 PM PST What tests are being done to determine if vaccination prevents COVID-19 from being transmitted from a vaccinated individual and when are we likely to see the results from this research? [link] [comments]  |
| How exactly do we absorb Vitamin D from the sun? Posted: 01 Jan 2021 06:51 AM PST I know it's something to do with the VDR (vitamin D receptor) and a chain of reactions that take place when exposed to sunlight, but what exactly happens? I can't find any papers that explain it clearly. Many thanks! [link] [comments]  |
| Do animals recognize people by their movement patterns like us humans do? Posted: 01 Jan 2021 06:42 AM PST I was observing a cat who was looking at its owner through a window. The owner was wearing full ski gear so the cat probably had a hard time seeing or smelling who it was. A human would see the movement pattern and recognize the owner that way so I wondered if animals in general lack this skill or if there are any that can do this? [link] [comments]  |
| Are there still Neanderthal X or Y chromosomes in any human populations today? Posted: 01 Jan 2021 06:11 AM PST All non-African humans have some small percentage of Neanderthal DNA, but are there any surviving X or Y chromosomes that are a result of direct descendancy from a Neanderthal ancestor? [link] [comments]  |
| Are there virus outbreaks in oceans? Posted: 31 Dec 2020 02:29 PM PST I'm just wondering if there ever has been a pandemic in the ocean that infected and killed a lot of fish and sea creatures? One would think that it being one massive body of water that that would happen very quickly. [link] [comments]  |

| Do brain regions of other animals match that of ours? Posted: 01 Jan 2021 08:11 AM PST We have a fiarly clear understanding of various parts of our brain to the point we can tell which part of brain is 'responsible' for which body function - emotions, memories, senses, etc. Do we know analogous regions for animals? Do they match in general area? Can we see correlation between more evolved features e.g. superior sense of smell of dogs, and larger area in the brain responsible for it? [link] [comments]  |
| Do ants, bees, wasps, or other insect colonies ever have civil war, or killing within one colony? Posted: 01 Jan 2021 07:41 AM PST I am excluding the colony's rejection of queens or queens having to kill each other to be the only one. I am thinking of regular worker insects killing each other or even more human-like, workers showing loyalty to different queens and these factions killing each other for control of the hive.

| How are genes expressed in different body parts? Posted: 01 Jan 2021 03:07 AM PST for example, do the eyes have a certain set of genes or for do all cells have the same set or genes but only certain genes are expressed in certain parts of the body? [link] [comments]  |
| How is groundwater oxygenated? Posted: 01 Jan 2021 02:41 AM PST If water needs to percolate many meters down into soil, how does it retain or gain oxygen if the area becomes saturated for ground water? Doesn't the soil material become anoxic or anaerobic? [link] [comments]  |
| Are there animals that resist electricity? Posted: 31 Dec 2020 08:05 PM PST Or other types of lifeform that have a better defense mechanism than humans? Any answer on either the biologic explanation or biochemical way it works would do wonders, thanks! [link] [comments]  |
| Cancer stage 1 to mestastisised stages - how does it happen? Posted: 31 Dec 2020 02:07 PM PST Ok so this question stems from both my limited understanding of how cancer forms and how it spreads. Note: I am also in the education sector (not biology), fairly new to reddit ( I know my students are here somewhere too) so I am eager to see how to source knowledge and understanding from online platforms. My current understanding of cancer cells forming is that mitosis can go wrong and abnormal cells may form as a result. (Primarily in their DNA sturcture). Our body usually triggers an immune response but in some case the mutation is aggressive/ rapid/ undetected which led to masses forming. I also understand that each tissue has specialist cells therefore I do not fully understand how cancers may spread from one organ system to another. What I am asking is as follow (and this could in the r/explainlikeIamfive subreddit): - How do cancer cells first form - in a little more detail because a google search kind of confirms my limited understanding. - how can a stage one cancer mass spread to a completely different type of specialised cell. Thanks! [link] [comments]  |
| Posted: 01 Jan 2021 12:15 AM PST One definition of species I've heard is inability to mate and produce offspring. Does the process even begin or does the sperm look up at the egg and say " Well boys no point in breaching that." [link] [comments]  |
| Posted: 31 Dec 2020 01:54 PM PST Would it be possible to genetically modify a common cold so that spreading it inoculates against COVID-19? The safest and simplest approach might be to modify the payload of a common cold so that it produces COVID spike proteins in addition to itself. Downsides I can think of:

| What keeps birds' legs from freezing in sub-zero winters? Posted: 31 Dec 2020 07:23 PM PST It often drops below -15C where I live. I see those thin little legs and wonder how they don't freeze and snap off. [link] [comments]  |
| Posted: 31 Dec 2020 11:11 AM PST Why are alpha particles easily more absorbed by our body? Is it because the particle is "big enough and have enough mass"? Is there probability at play here? Meaning since the alpha particle is "bigger and slower" the probability of alpha particles ionizing atoms in our cell is higher than the energy richer and smaller beta particle and than the rays of gamma? Is that right? Could someone please clarify this for me? Thanks y'all. [link] [comments]  |
| Can the frequency of hair/skin washing change the rate at which oil (sebum) is produced? Posted: 31 Dec 2020 02:49 PM PST It's often said that washing your hair/skin too often will lead to increased sebum production. It's also claimed that when you reduce the frequency with which you wash, your skin/hair will be extra oily, but that after a while your body will return to normal production rates and your skin/hair will no longer be oily. Is there any scientific basis to these claims? If hair and the outer layer of skin are not living tissue, how does your body sense how oily they are and signal for increased sebum production?
