Radiation can be defined as the energy that travels through space or through a material medium in the form of particles or waves. Depending on the energy of the radiated particles, radiations can be categorized into two groups: Ionizing radiation:...
The word “catalyst” is derived from the Greek word katalyo, which means “to pick up,” or “to unite,” or to annul.” The concept of the catalyst was first described by chemist Elizabeth Fulham in 1794. She...
Anyone with the basic understanding of cosmology is aware of the certainty that, sometime in the distant future, our Earth will die. But the question is how and when. The death of the Earth can be explained in two ways; biologically and geologically...
The new research shows that the origin of photosynthesis in today’s plants had begun nearly 1.25 billion years ago. Previous studies had placed it somewhere between 0.7 and 1.2 billion years. Researchers put “Bangiomorpha...
Researchers achieve detailed high-speed imaging of the microparticle impact process. The study revealed that both the surface and the particle melt to some extent at high impact velocities. The combination of high temperatures, pressures, and...
The new method can use any pliable molecule to write, store, and read data. It is cheaper and less labor-intensive as compared to DNA-based methods. The ‘reading’ averages 20 bits/second while ‘writing’ averages 8...
Different types of sensory instruments are used to determine the location and orientation of an object. The two most common of these instruments are the accelerometer and the gyroscope. When integrated into a signal device, they produce incredibly...
Researchers revisit the concept of a space elevator with a minor modification. Instead of anchoring the cable on Earth, anchor it on the moon and dangle it toward Earth. This would make lunar and terrestrial gravitational pull cancel each other...
Thermal energy refers to the energy possessed by an object due to the movements of particles within the object. It’s the internal kinetic energy of the object, which comes from the random movements of the object’s molecules and atoms...
Scientists produce an astonishingly loud sound underwater, louder than the sound of a rocket launch. It generated 270 decibels of sound pressure levels and 1GW/m2 of sound intensities. Sound is defined as a longitudinal wave created by compressions...
We need to be more specific when talking about how heavy an element is. There are two possible ways to define the “heaviest” elements – based on their density or atomic mass. The heaviest element in terms of density can be defined...
What happens when you leave a bowl of hot soup on a table? It gets cold after some time due to the loss of heat to the surrounding air. And that’s (transfer of heat) what we call convection. There are three types of heat transfer: radiation...
