Your Happiness May Depends Upon Genes

Gene is unit of heredity in all living organisms. A gene is part of a DNA molecule within the nucleus of all cells. Each gene codes for a particular protein. Thus a gene is a unit of the inheritable characteristics of the organism. Humans have tens of thousands of different genes; these determine the phenotype of the individual.

According to new study our level of happiness throughout life is strongly influenced by the genes with which we were born.

An Edinburgh University study of identical and non-identical twins suggests genes may control half the personality traits keeping us happy. The other half is linked to lifestyle, career and relationships.

So if you are not happy, just blame to your genes ;). On a related note positive thinking may improve overall life.

Why Some Human Races Are More Vulnerable To Disease

An immune system is a collection of mechanisms within an organism that protects against disease by identifying and killing pathogens and tumor cells. It detects a wide variety of agents, from viruses to parasitic worms, and needs to distinguish them from the organism’s own healthy cells and tissues in order to function properly.

Now researchers have found the behaviour of immune system genes varies from race to race – potentially affecting how they respond to infection. The Chicago University team looked at over 9,000 genes in 180 people, half Caucasian and half from Nigeria. They found differences between the two races in 5% of key genes. The American Journal of Human Genetics study may help explain why some groups are more vulnerable to disease, and aid development of more tailored treatment.
