The act of touching helps form social relationships between people through a physiological process that involves hormones, in particular cortisol, heart rate and body temperature. Specific skin nerves respond to delicate touch, particularly caresses, but not to rapid caresses (faster than 10 centimeters a second) or to rubbing. The stimulated nerves reach brain areas that...
Human newborns are the only mammals that do not stand up soon after they are born. Elephants, giraffes, and horses take a few steps just a few minutes after they are born. Before a human newborn does anything similar it will take about a year and during that time it will roll and drag itself...
Puberty is the time when changes in boys and girls gradually take them into adulthood. These changes used to begin around the age of 14 years.

We all know that eating fish is good for one’s health. An association has been observed between diets rich in omega 3, a particular type of fat, and the development of intelligence. Still other studies have described an association between quality of sleep and omega 3 in the diet. A recent study has now established...
The number of road accidents involving motorbikes, bicycles and other two-wheel vehicles is relatively high with respect to the total number of accidents. The reasons given are often obvious and based on the fact that a two-wheel vehicle is less stable than a four wheel one. Clearly, the passengers of, say a scooter, run greater...
Imagine you are walking down a crowded street. You pass thousands of people, but you only notice a few faces while the many others are ignored.
