How does a painkiller know exactly where the pain is?
Neil Gupta , Chennai
The medicine in a painkiller doesn’t go directly to where the pain is. Instead, it just goes everywhere. When you swallow the tablet, it goes from your stomach to your bloodstream. When the cells in your body are injured, they release a chemical called prostaglandin which makes your nerve endings tell your brain that it hurts in that area. When the painkiller that you have swallowed kicks in, it prevents injured cells from releasing prostaglandin. Your brain then stops receiving pain messages, and you stop feeling pain.
What is the longest time a person has spent on the moon?
Anubhuti Banerjee , Thane
Astronaut Edgar Mitchell was the sixth man to walk on the moon. He was a pilot on the record-setting Apollo 14 mission in 1971. He is recorded to have spent the longest lunar stay time - 33 hours. The astronauts on this mission were also the first to transmit colour pictures from the moon. During his exploration of the lunar surface, Edgar Mitchell helped collect more than 42 kg of lunar rock and soil samples.
Why are planets spherical in shape?
Advika Patalay , Secunderabad
The reason planets are round, and not shaped like cubes and pyramids, is gravity. When our solar system was forming, the force of gravity gathered billions of pieces of gas and dust into clumps which grew larger and larger to become the planets we know today. A planet's gravity pulls equally from all sides. It pulls from the center to the edges like the spokes of a bicycle wheel. This makes the overall shape of the planet a sphere.
Why do we get goose bumps?
S. Srinikesh , Madurai
Getting goose bumps is a reflex action, something your body does without you even thinking about it. When you get cold or experience a strong emotion such as fear, your brain sends signals to your muscles, making them tense up. When the muscles in your skin that are attached to the hair follicles do this, they make the hair stand and pull your skin up just a bit, creating goose bumps. Did you know that the phenomenon got its name because the bumps look similar to the skin of a goose whose feathers have been plucked out?
