Everything in the Universe — from Earth’s core to farthest galaxies — is made of atoms. It’s a fundamental unit of an element. So far, 118 elements have been identified (all are listed in the periodic table). The word...
Holograms are virtual 3D images generated by the interference of light beams that reflect off real, physical objects Holograms retain the depth, parallax, and other properties of the original object. They are excellently suitable for presenting...
In physics, energy can be defined as the capacity to do work. Just like there are many different ways of doing work, there are also different types of energy. Energy is a quantitative property. As per the law of conservation, energy can neither be...
The term ‘Potential Energy’ was coined by a Scottish mechanical engineer William Rankine in the 19tn century. It soon became one of the most influential variables in the formulas the describe our known universe. What Is Potential Energy...
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...
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...
Using artificial intelligence, researchers found a powerful antibiotic named halicin. It kills harmful bacteria, including ones that are resistant to all existing antibiotics. It has a different chemical structure from all known antibiotics and...
Researchers discover a new type of antibiotics that kill bacteria by taking a unique approach. Usually, antibiotics such as penicillin prevent building of the bacterial wall around the outside of their cells. New antibiotics do the opposite: they...
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...
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...
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...
Researchers develop an effective and inexpensive device that identifies a broad range of viruses within minutes. The device is called VIRRION. It utilizes Raman spectroscopy to identify viruses based on their individual vibration. Viruses are...
