Can twins feel each others pain? Do they have mental connections?

Some twins say that they can feel each others pain but they might be making it up. Scientists still haven't proven anything but it may be possible. 

Personally, I don't think this is possible as after twins are born, their brains develop separately. If it is possible, I think it would only happen with identical twins as they share the same genes.


 


Twins have connections that no normal brothers or sisters have.  Some say that they have mental connections and they can guess what the other twin is thinking. This may be linked to feeling each others pain.


A set of twins who lived in different countries once bought the same trousers, in the same colour, from the same shop, on the same day. They did this without knowing but they must have had an urge to buy them.


Also, a twin went into labour and the other one got cramps as soon as she did.  another example of twins feeling each others pain is that once, a twin hurt her knee and the other twin started limping.


These are all examples of how twins have mental connections. Thank you and  I hope you enjoyed this post. I'm so sorry I haven't posted for ages! See you soon!

Why can't humans breathe underwater?

When we go swimming, we hold our breath under the water. It is just a habit that we all do but why can't we breathe? Water has oxygen in it as it is H2O so surely it could go round our bodies like air. Also, water is just another state of air and the molecules are a bit further apart. But apparently this makes a big difference on what we can and can't breathe.


Water is made of hydrogen and oxygen gas. The reason that we can't breathe water is is because the oxygen is bonded together with 2 atoms of hydrogen and the oxygen is then useless to our lungs in this form. Also, humans can't breathe underwater because our lungs don't have enough surface area to absorb enough oxygen from water as there is not that much in it. The lining of our lungs, also is adapted to handle air rather than water. However, scientists have done experiments where they make humans breathe other liquids like fluorocarbons. Fluorocarbons can dissolve enough oxygen so that we can breathe.

Are chickens really related to dinosaurs?

I've heard that chickens are related to dinosaurs but I don't really understand how that is possible! They look COMPLETELY different! First of all, chickens have feathers and have beaks and also, chickens are much smaller! I have done some research on why scientists believe that they are related and here is what I've found:





Scientists believe that birds evolve from dinosaurs because of the architecture of the bones. Also, extracts of  T. rex's bones reacted with antibodies to chicken collagen which is a further suggesting the presence of birdlike protein in dinosaur bones.



Scientists still don't know if this theory is correct as it is very difficult to discover.  Dinosaurs, as you all know, are extinct which means that scientists can't do any tests on them to see if they are correct.


 I think that it may be possible for this to be true but it must have happened over billions of years. As we evolved from monkeys, chickens could have evolved from dinosaurs. If you look at the picture above, you can see how dinosaurs began to look like chickens. Although it is a bit odd for it to shrink in size, you can see the resemblance between the pictures.

Why do clouds change colour?

Have you noticed that clouds change colour over time? They start off as white and fluffy and then turn to heavy, dull, grey clouds. Isn't it strange?! There are a few different ideas on this and here are some of them!


WHY?! HOW?!


Some people say that the heavier the cloud is, the darker it gets. This may be because the sun can't get through the heaviest clouds so makes them darker. After evaporation occurs, water drops form around dust and when they get heavy enough, it rains! This happens everywhere around the world but a lot more often in some places *cough*England*cough*.

Other people say that clouds look grey when we are directly underneath them. This might be because the sunlight doesn't shine directly on the bottom of clouds, but through the top of the clouds. 



The sunlight has to travel a very long way to get to our eyes. As the light travels through a thick cloud, the light will get scattered and reflected off things so when the light eventually reaches us, it will look different.

If all the colours in the spectrum are there (red, orange, yellow, green, blue, indigo, violet) then the colour of the light is white. If none of the colours of the spectrum are there, the colour is black. This may also be why clouds look different colours. It just depends what colours can get through the clouds!

What did it look like before the big bang?

Science is such an amazing subject and you can learn so much from it. But first you have to get your head around it all! This question is beyond anyone's mind but I keep asking it to myself. What was it like before the big bang? What colour was it? Was it white or black? Or maybe even pinkIt can't have been see-through because there would have to be something BEHIND that... It is beyond anyone's imagination...



This shows what scientists have discovered about the big bang so far. It is so advanced but amazing how they could find this out from hardly anything!

Scientists believe that the universe was a teeny-tiny speck of dust which then exploded. But how is that possible? I still don't understand how people have found this out though... It must have taken YEARS of research!



The universe is also expanding as we speak but into what? It is travelling so fast but where to? There has to be SOMETHING outside of it... Maybe another world like one of my previous posts or maybe it looks like what it did billions of years ago before the big bang happened.

I wonder if anyone or anything was alive to witness the big bang... But that isn't possible is it? And even if someone WAS there, they would have died in the bang...

There is no true answer to this mystery so I'll just have to leave it there. Thank you for reading this post and please explore the new pages that I have put at the top of the page. There is a whole page for questions you want me to answer so please comment! I would love to hear your opinions too and you can comment on this post! See you next week!

Why do some men go bald and others don't?

This question was asked to me by The Apologist. I give a very special thank you to The Apologist and you have been a great reader. I hope you like the answer!

Some scientists say that going bald has something to do with your sexual hormones and one way to ensure against hair loss is to sacrifice something else. For example, during the Middle Ages and nearly into the 1800s, certain choir boys with very beautiful voices were castrated before reaching puberty to avoid the change of voice. Scientists say that these boys didn't go bald and it makes it clear that sexual hormones play a role in hair loss.



I don't think you should sacrifice something like that just to keep your hair on your head. People look just as good without hair and besides, if you DO keep your hair, it will eventually turn grey and not many people want that...!




Hair loss probably also gets passed down to your children so if your grandpa has no hair, then you probably won't have any when you are his age as well! But you never know, you might not have that gene!

Thank you everyone and please comment with your opinions and questions that you have been wanting the answer for. See you next week!

Why do flamingos stand on one leg but have two?

Humphrey Cushion asked me this question and I am going to try and answer it. Thank you Humphrey Cushion and please check out her blog at: 
http://the-pop-corn-page.blogspot.co.uk/

This is a very strange question and I think there probably is an answer. Scientists say that there may not be a simple answer but there are still some theories.

Flamingoes stand on one leg mostly when they are in the water. This may be because they are trying to conserve body heat. If they put both their feet in the water then they would get much colder than if they stand on one leg, they would also get very cold because they spend a lot of time in the water. Flamingos regularly change what leg they stand on in the water so that one foot doesn't get too cold. It's quite clever really!




Flamingos stand on both legs when they eat, but one leg to sleep. This sounds quite strange as you would think that sleeping would require both legs on the ground for balance. Especially as they are practically unconscious when they are asleep!

Fun fact: The colour that a flamingo is comes from the food they eat, including shrimp, which is full of carotenoid pigments (the same thing that makes carrots orange!)
