@K Lawrence, that's a bit of an oversimplification. Carbohydrates, which the body converts to glucose, is the primary source of energy utylised by the central nervous system for brain and nerve function. If carbs aren't available, the body can use fats or proteins for this purpose though.
This supports the out of Africa hypothesis. The article doesn't really make it clear, but these genes have been found in all races except Africans. One logical explaination is that when humans first migrated out of Africa to Europe, they then interbred with Neanderthals (who migrated to Europe first), passing the genes on as they colonised the rest of the world.
Awesome. More theatres should also install FM systems so that individuals with hearing aids can have the sound signal transmitted directly to their aids.
...Carl Sagan also talks a lot in Cosmos, and was a strong promoter of the need for humans to fund space exploration technology so that one day we will have the technology to find a new planet when we destroy our own.
@emiiiiiiil, speak for yourself. Your comment sounds no more mature than that of a 12 year old. Do you enjoy mocking the inquisitive questions of kids and branding them as uneducated while hypocritically abusing spelling and grammar?
@xXechoXx, you raise some excellent points. There is nothing paranormal about believing in the possibility of alien life on another planet. In fact, the law of large numbers states that with a large enough sample size, any unlikely thing is likely to happen. As a result, most scientists believe that the probability of life elsewhere in the universe is highly likely.
If there were life on another planet, that doesn't necessarily mean it would support human life. Alien life forms could be so different from us that they may not even need water or oxygen to survive. As a result, any planet that could be considered as a potential refuge for humans in the future when our own planet is destroyed and we have developed the technology for interstellar space travel, would have to be quite similar to the Earth. This means that it would likely need to have an oxygen-rich atmosphere so we can breathe, and water. It would also have to be at a distance from its star that is not to hot and not too cold, an area which scientists call "the Goldilocks zone". It would also have to be close to the size of the Earth so that the gravity is not too high or low. Too high and we could be crushed or would not be able to move around very easily, and too low would mean that our muscles would waste away and our bones would become brittle and we humans would develop osteoporosis. As a result, even if this diamond planet could support life, it is very unlikely that it could support human life. That doesn’t mean that there aren’t lots of other planets out there that could support human life, just waiting to be found. Scientists are finding more Earth-sized planets all the time and it won’t be long before we have the technology to find out whether these planets have water and oxygen atmospheres too.
Keep up the enthusiasm about discoveries and astronomy! If you want to learn more about astronomy and science, I suggest you watch YouTube clips by Neil deGrasse Tyson, who is hilarious but also educational, and “Cosmos” by Carl Sagan – it’s a series that while a little bit old, is still mostly up to date and inspired lots of kids to grow up to become astrologers and scientists.
