Does falling in love really causes changes in your brain?

There is indeed a biochemistry of love. Helen Fisher, an anthropology professor used an MRI machine to study the brains of people who describe themselves as being wildly "in love." When each subject gazed at the photograph of his or her sweetheart, the ventral tegmental area and caudate nucleus lit up. The caudate nucleus is a site of dense receptors for the neurotransmitter dopamine. 

                                    A psychiatry professor measured the serotonin levels of the neurotransmitter serotonin in the blood of the people who'd been in love for several months and who pine or are otherwise preoccupied with their lovers for at least four hours a day. She found that the serotonin levels of love-struck people were as low as the serotonin levels in people with obsessive-compulsive disorder (OCD).

                                        So if you're feeling "madly" in love, or a little insane, or crazy for feeling so lonely, there's a solid, scientific basis for losing your heart AND your marbles.

Thanks for giving your precious time.

Is it true that cockroaches can survive atomic blast ?

Let's talk about atomic blast before answering the above question. But wait, do we know about atoms. So, first of all I will tell you about atoms.

Atoms are the smallest individual parts of an element. Two or more atoms join together to form a molecule of a substance known as a compound.

You have probably heard about the atom bomb dropped by USA on Hiroshima and Nagasaki on August 6 & 9, 1945 respectively. Now, you can imagine the devastating effect of an atomic blast. But how do cockroaches can survive atomic blast ? Here is the answer.

They could probably withstand the radiation in a thermonuclear blast. If we talk about ourselves, we would probably die if we are exposed to radiation greater than 800 rems. Now what is this rems. REM is a unit of radiation derived from the phrase Roentgen Equivalent Man. 

But guess what how much amount of radiation will be required to kill a cockroach. It requires more than 84 times of rems that of human beings to kill the cockroach by radiation. In other words, 67,500 rems.
