Don’t you remember, as a child, holding a lizard in your clenched hand, only to find its wriggling tail when you opened it? Although it is a traumatic experience for the creature, it is thrilling to the mischievous, inquisitive young mind. A few days later, in your backyard, to your amazement, you might have observed the same lizard with a small growth from its broken tail! Some lizards and other animals can lose their tails or arms, but quickly grow new ones. You might wonder why it did not happen to other animals. You might also ask, why humans aren't [...]

The 2022 Nobel Prize for Chemistry was awarded to a trio for the contribution of "click chemistry and bioorthogonal chemistry." Click chemistry is a new method of manufacturing molecules that can accelerate drug discovery by utilizing a few practical and reliable reactions. The winner of the 2022 Chemistry Nobel PrizeDr. Carolyn R. Bertozzi is a Professor of Chemistry at Stanford University. In 2000, she started utilizing click chemistry in living organisms. She developed a bioorthogonal method which involves a set of reactions in living organisms. These reactions, though, do not disrupt the cell's regular activity. Such reactions are used to [...]

Photonics is the science of light. It is the technology of generating, controlling, and detecting light. Scientists have been studying light for hundreds of years. At the beginning of the 20th century, Max Planck and later Albert Einstein proposed that light behaves as a wave as well as a particle, which was a very controversial theory at the time. How can light be two completely different things at the same time? With experimentation, this duality of light was confirmed. The word Photonics appeared around 1960, when the laser was invented by Theodore Maiman. It brings together physics, electrical engineering, and [...]
