Question:

Working out may be a hobby to a lot of us, but some of us might want it professionally and in doing so, how man times have you heard someone injecting steroids for a quick six-packs? Ever wondered how does this actually happen?

Answer:

Well, steroids are basically a group of hormones - biochemical molecules generated from endocrine glands. Steroids help in producing proteins and preventing the effects of cortisol -a hormone that often acts to increase protein supply in the liver leading to increased protein catabolism (break down of proteins) thus reducing muscle mass. Preventing cortisol increases our muscle mass. Gradually the muscles turn into biceps, triceps and six pack abs. However, steroids are recommended by doctors to increase the appetite and sometimes they help in stimulating muscle mass in chronic wasting conditions like cancer and AIDS. Next time, be sure to share this with you friend who is passionate about working out!

Question:

Why is it that water we drink or use for our household chores appear colorless but ocean waters are blue?

Answer:

All throughout high school we all have been taught as water to be the only liquid which is colorless, tasteless and odor less. But, is it really? When asked the question about why ocean waters are blue you can certainly say that they are so because they reflect the light from the sky. However, there is more to it. Water actually is shown to have a slight intrinsic blue color. It takes a large quantity of water, like in the ocean, for us to notice the blueness. In household uses, like when drinking a glass of water, we use far too little water to notice its blueness. As a result, we think it is always clear. According to these scientists Braun and Smirnov, water absorbs red light due to vibrational transitions of its molecules, which is quite common as the sea water is constantly in motion leaving the blue light to reflect back. For the same reason, large volumes of snow and ice also have a blue tinge. Laboratory experiments have also verified the faint blue color of water even when only a cupful is present. There you go, next time in a class debate you can surely bring this up and educate your peers!

Question:

Headaches are pretty common in the stressful world we are living in and to combat with that we often take the help of painkillers. But, have you ever wondered how an aspirin magically takes your pain away?

Answer:

Headaches are a way of our brain telling us to take things lightly. While you can opt to de-stress all by yourself, sometimes pain killers save the day. They basically work by preventing a 'pain signal' that transmits from the spinal chord to the brain. However, there are mainly to types of pain relieving medications (Aspirin type and the Narcotics type) that prevent this signal in their own ways. The Aspirin-type painkillers block the body's prostaglandins - molecules responsible for pain and swelling. Blocking prostaglandins blocks the signal at the source of the pain, as well as reducing swelling. The Narcotic-type medicines block the pain messages in the spinal cord and the brain, and are typically used for much more severe pain relief. So, next time you take a painkiller after a stressful school day or an accidental injury you will know what it is doing to your body.
