Have you ever been kind to someone and wondered why they could not offer you the same kindness in return? It can hurt, especially when your intentions were genuine. But here is something worth remembering: your kindness reflects your values, not necessarily the character of the person receiving it. Kindness - A jewel few possess The Biology Behind Kindness Kindness is more than a social virtue; it is connected to the biology of our brains and bodies. When we engage in compassionate behaviour, neural networks involved in empathy, reward, and social cognition become active. Oxytocin , a hormone and neuromodulator involved in social bonding, may contribute to feelings of trust and connection, although its effects depend on context. Acts of kindness can also activate the brain's reward circuitry, making helping others emotionally rewarding. Furthermore, supportive social interactions can help regulate stress responses. Feeling understood and connected may reduce perceived stress, while...

Have you ever had things to do, dreams to pursue, and responsibilities to fulfil, yet found yourself wanting to do absolutely nothing? Perhaps you have called yourself lazy, questioned your discipline, or wondered why you cannot simply get moving. If that sounds familiar, take a gentle breath. You do not have to solve everything right now. You are a human being, not a machine, and not every period of inactivity is a failure. What Is Happening Inside Your Brain? Not feeling like doing anything Motivation is a biological process, not merely a matter of willpower. Dopamine , a neurotransmitter involved in reward anticipation, learning, and motivation, helps your brain evaluate whether an action is worth the effort. When you feel overwhelmed, exhausted, or emotionally drained, even ordinary tasks can seem unusually demanding. Prolonged stress can disrupt the hypothalamic–pituitary–adrenal (HPA) axis , the body's central stress-response system, affecting sleep, concentration, and emotio...

Let us begin with a little kindness towards ourselves: talking about someone who is not present does not automatically make you a bad person. Most of us have, at some point, shared our frustrations, questioned someone's behaviour, or sought comfort by discussing a difficult relationship with someone we trust. Sometimes, we simply need to be heard, to understand what happened, or to reassure ourselves that our feelings are valid. What matters is not merely that we talk about others, but why we do it, how we do it, and what our words ultimately accomplish. What Happens in Our Brain? Funny how the story changes when the storyteller once stood on the other side. Sometimes, the loudest whispers come from those who remember being hurt by the very same words. Humans evolved in social groups where recognising trustworthy individuals, identifying threats, and understanding group relationships could influence survival. Gossip became one way of exchanging valuable social information. Our brai...

The Carcinogenic Pujas: When Celebration Meets Chemistry The science of festive smoke, toxic air, ultra-processed food and the invisible price of celebration. What if the air we breathe during our most beloved festival carries a chemical burden that outlasts the celebration itself? Durga Puja is a celebration of triumph, artistry, devotion and community. Yet, beneath the illuminated pandals and festive feasts lies a less-discussed scientific reality: the chemistry of combustion, the biology of air pollution and the cumulative risks associated with certain food-processing practices. The question is not whether Durga Puja causes cancer, but whether some of the ways we celebrate expose us to avoidable carcinogens. The Chemistry of Festive Air Incense sticks, dhuno, candles, oil lamps, firecrackers and vehicle emissions can release a complex mixture of airborne pollutants. Incomplete combustion produces fine particulate matter (PM₂.₅), carbon monoxide, volatile organic compounds and, depen...

The people who make you powerful may one day become your greatest threat. And the people who promise to stand by you may be the first to abandon you.   Credit: FST This is the unsettling paradox of loyalty, especially when extraordinary talent enters the equation. The Burden of Being Exceptional Exceptional talent is a double-edged sword. It attracts admiration, creates opportunities, and drives progress—but it can also expose the insecurities of those who hold power. A visionary who once seemed indispensable may eventually appear intimidating. Their success challenges hierarchies, their independence threatens control, and their brilliance can turn admiration into envy. Sometimes, the greater the contribution, the greater the perceived threat. Thus, those who build institutions, transform teams, or redefine possibilities may find themselves sidelined by the very systems they helped elevate. When Loyalty Breaks from Within Yet extraordinary individuals are not merely victims of betr...

Nobel Prize in Chemistry 2026: How Can Life Become Homochiral? From a tiny chemical imbalance to the “one-handed” chemistry of life All about Nobel Prize in Chemistry 2026: How Can Life Become Homochiral? Credits: @FST On 7 October 2026 , the Royal Swedish Academy of Sciences awarded the Nobel Prize in Chemistry 2026 to Henri B. Kagan of Université Paris-Sud, France, and Kenso Soai of Tokyo University of Science, Japan, “for the discovery of non-linear effects and autocatalysis in asymmetric organic synthesis.” Their work addresses a fundamental question in chemistry: how can a chemical system containing two possible mirror-image molecules develop a strong preference for one of them? This question leads directly to one of biology’s most intriguing chemical features: homochirality . Before going further, one terminology point is important. Homochirality means a strong preference for one molecular handedness. Homomers , by contrast, are molecular assemblies made from identical subuni...

Author: Anneswa Das Have you ever wished you could just reach into the brain and flip a switch to turn off a migraine, calm an anxiety attack or bring back a lost memory? For decades, doctors and neuroscientists could only dream about something like that. The human brain is home to over 86 billion neurons, all working at once or as according to situations.  Trying to understand which specific cells cause a panic attack or trigger a tremor was like standing in the middle of a roaring stadium and trying to pick out a single person’s voice. As for it's solution, medicines flood the whole brain and cause side effects. While if you used electrical stimulation, it erases everything nearby without discriminating. Then came Optogenetics — a breakthrough so revolutionary that it was awarded the Nobel Prize in Physiology or Medicine in 2026 to joint awardee to Karl Deisseroth (Stanford University, USA), Peter Hegemann (Humboldt University of Berlin, Germany), and Georg Nagel (University of ...
