Is there a gene for the “promiscuous” host range in symbiosis?
Root nodule symbiosis is a mutually beneficial relationship between legume plants and nitrogen-fixing bacteria called rhizobia. In this process, the legume plant provides the rhizobia with a place to live and access to energy in the form of sugars, while the rhizobia fix nitrogen from the air and convert it into a form that the…

Mass in Special Relativity: Is Relativistic Mass Real?
The speed of an object can never be equal to or greater than the speed of light – we all know it more or less. Even having no knowledge of special relativity, it is no longer unknown to curious readers with the help of popular science content. Naturally, many of them wonder why an object’s…

Why Meselson-Stahl Experiment is Called the Most Beautiful Experiment in Biology
Experiments in biological research can be messy. To begin with, biological systems are inherently highly variable, and you need to have good control. Then there come reagents that are so finicky that they need a super pampered buffer solution. Everything has to be in just condition and then there is the challenge of reproduction. That’s…

Ignaz Semmelwies: The Pioneer of Hand-wash
Hand-washing is one of the first lines of protection against the transmission of the coronavirus, and it can feel distinctly low-tech. This very simple act of hand-washing has been proven to be a vital step in preventing the spread of germs. Nevertheless, the link between handwashing and disease transmission was uncovered only two centuries ago, which…

Gene for Gene vs. Matching Allele (and their variations)
Understanding the host-symbiont relationship has many facets. Often we borrow ideas from host-parasite interaction literature of co-evolution. You can think of host-parasite interaction as a continuous war between two parties where one party is always trying new ways to abuse the ‘host’. On the other hand, the host needs to upgrade itself against those new…
