There are some facts and theory's already present with the masculinity of a person and testosterone levels. But what about their appearance, is a connection present? Well there may be a slight break through in the testosterone levels at birth and their changes during puberty to becoming adults.
As the new iphone 6s has just lunched with its new feature of video loops. Facebook seems to be the first to make use of the this feature with you eventually being able to add video loops to your profile picture.
As of the 19th February 2015 Nash Riggins (American Journalist based in Scotland) released an article relating nicotine to poison and not to be taken lightly, with the likes of e-cigarettes being safer than the real thing.
So as for our chemical of the week will be looking at what nicotine is and the effects it could possibly have on us.
Although the reason is obvious on why we sleep, but the real truth is that there is very little knowledge explaining as to why we fall asleep and why we wake up at particular times?
Also why it is sometimes that we can wake up feeling refreshed and other days just feeling so annoyed and drowsy?
So before we start looking at the correct times to sleep we should take a look at some of the science behind sleeping. Feeling tired and not feeling sleepy is primary down to two different chemicals: Acetylcholine and adenosine. Acetylcholine is responsible for keeping us awake, whereas adenosine has the opposite effect making us feel sleepy.
These two chemical are constantly in a 'battle' with each other; adenosine builds up when we are awake and when we sleep acetylcholine take its turn to overcome the adenosine which will eventually have us waking up. Other chemicals which are involved in making us feel sleepy and then making us wake up are cortisol (an awake hormone) and melatonin (sleepy hormones)
So what is there to love about chemistry? Lets find out.
What is chemistry?
Chemistry is amazing, there is so much more to discover but for now check out these videos
Who says chemistry needs to be complicated?
Reactions can be very basic, in fact cooking an egg is an example of a chemical reaction, these reactions are seen as non-reversible. The properties at an atomic level have changed and thus meaning that it cannot change back into the structures the atoms had previously. Another good example would be a firework, the rapid oxidation is an example of a chemical change.
