Talks from the Bio lab desk

When you bite into a juicy, sweet mango or a perfectly soft peach, you’re enjoying the result of a fascinating biological transformation.  Fruit ripening.  This natural process is not just about getting sweeter or softer, it’s a complex dance of chemistry, biology, and evolution that turns a hard, sour fruit into a delicious treat. What Is Ripening? Ripening is the final stage of fruit development, occurring after the fruit has grown to full size. During this phase, a fruit undergoes biochemical and physiological changes that make it more appealing to animals, who, in turn, help disperse the seeds. Ripening can change: - Color - Texture - Flavor - Aroma - Nutritional content These changes are triggered and regulated by plant hormones , particularly ethylene . Ethylene: The Ripening Hormone Ethylene is a naturally occurring plant hormone in gaseous form. It acts like a signal that tells the fruit, “It’s time to ripen.” Once ethylene is released, it sets off a c...

It's that moment at the gym. The heavy lifters are going at it, and taking up every ounce of weight they can find and you through the occasional glance at them with your little weights, while struggling.  Maybe you are also thinking of testing yourself or your limit, because, no pain, no gain, right? But then you wobble and shake at the increase of those weights, and maybe create quite the comical experience. Sometimes you leave, feeling you need a better pump than the grunting muscle bulging gym rats, but aren't they both workouts, with light and heavy weights? Therefore. Think back to two very different workouts: -   One where you pushed a near-max deadlift bar bending, jaw clenched, tunnel vision. - Another where you breezed through high-rep bodyweight squats or light dumbbell curls. They both make you sweat. They both engage your muscles. But internally, your nervous system is doing completely different things. Let's get the class....uhm, gym session, or.....

  You know that feeling, when you are new to the gym, or it could be your first workout, and you are told to perform an exercises in a particular way? The first few times you try the new movement, everything feels clumsy.   You overthink each step, your timing is off, and your muscles seem confused. Then a few workouts later, it suddenly clicks. You're smoother, more confident, and more precise. Who is the real culprit here, playing tricks? The muscles or having to get used to it? Who tells the muscles and how do they learn? What changed? Surprise!!!  It's not just your muscles getting stronger, but your nervous system is learning, adapting, and optimizing the movement. Think of it as the first day of a new topic your teacher is introducing. You probably will ask a few questions after class, go online or to the library to check it out, and possibly after a few lessons, you can get clicking on things. The process of improving an exercise is largely neurological at the ...

You’ve been at it for 45 minutes. Your form’s starting to slip, your focus is scattered, and your legs feel like jelly. Things feel a little bit hazy at this point. This when you begin talking to yourself. You tell yourself it’s just muscle fatigue, and you can get through it with some hard grunting and a lot of self-belief. A few minutes into the biggest push to get those extra reps, the dwindling and jelly-like legs come greeting you like waiter before you seat at a restaurant.  So what's the full story? A bigger push? Well, evidently not. So fatigue, that common foe, that hits any gym going or physical exercise enthusiast. You meet again, this time with no idea how it just happens. Fatigue strikes again, episode 1 or probably many, given the attempts you'll take to keep pushing.  However, fatigue isn’t just about tired muscles or low energy, another component, which is your nervous system plays a critical role in when, how, and why you hit that wall. In fact, what you f...

  It’s the last two minutes into your workout. Your heart is racing, your breath’s quickening, your limbs are moving like they know exactly what to do.  Then maybe, just maybe, you're starting to regret that extra set. Yeah, I know, every person who has set a goal in the gym or workout time has gotten to this point. You started having conversations with yourself and the set on how to sort it out, but before you know it, you've already gone past the rest time or your fitness coach is yelling in your ears to get back on finishing the set. However, in the midst of your troubles, have you ever paused to wonder, what's actually happening inside your body to coordinate all this? So, probably you have forgotten the Biology classes in high school and don't want to remember teacher, b ut let us get to this matter.  What you feel physically during a workout is just the visible part of a much larger biological symphony, and at the center of it is your nervous syste m . Yeah, it...
