What Is String Theory? A Simple Overview

String theory says that indivisible subatomic particles are made of tiny little strings vibrating in a specific pattern.  Each vibrational pattern corresponds to a different particle. Electron is nothing but a string vibrating in one pattern, and a...

10 Best Examples Of Kinetic Energy

Kinetic energy is the energy of motion: if something is moving, it is said to have kinetic energy. According to classical mechanics, the kinetic energy (E) of a non-rotating object depends on its mass (m) and velocity (v). E = ½mv2 Since energy is a...

What Is Hawking Radiation? Is It Proven?

Hawking radiation is thermal radiation spontaneously emitted by black holes, due to quantum effects near their event horizon.  It gradually decreases the rotational energy and mass of black holes. However, it’s just a theory; no such radiation...

A Whole New Way To Study Lunar Samples

Researchers use Atom Probe Tomography to analyze lunar soil. The technique uses only a single grain of soil to identify helium, pure iron, water, and products of space weathering.  This is the first time a sample extracted from the Moon has been...

Scientists Find How Stress Turns Your Hair Gray

Researchers establish a link between stress and hair graying.  Under stress, sympathetic nerves release the chemical norepinephrine, which plays a major role in stress-induced hair graying.  Stress can have several adverse effects on the body. One...

A New Formula For Measuring Hawking Radiation

Physicists develop an analytical formula for measuring Hawking radiation on the black hole’s event horizon.  It will help scientists test the accuracy of different quantum gravity theories.  In 1975, Stephen Hawking published a theory stating...

Can There Be An Easy Alternative To Exercise?

Scientists study a type of naturally occurring protein known as Sestrin.  It can mimic various effects (benefits) of exercise.  The experiments with mice and flies have shown that Sestrin upregulation mimics both molecular and physiological effects...
