What Is Intelligence? The Farmer, the Fish, and the SpermatozoonWhat is intelligence? Despite centuries of debate, we have no universally accepted definition. The author questions our habit of treating human cognition as the universal standard by which all life must be judged.We call ourselves Homo sapiens—the wise human. Yet our history includes slavery, caste discrimination, war, and environmental destruction. Our ingenuity has given us extraordinary power, but not the guarantee that we use it

Our Microbial Menagerie

Our Microbial MenagerieFor centuries, medicine quite rightly taught us to fear microbes. Pasteur and Koch transformed our understanding of infection, while antibiotics, sanitation and vaccination saved countless lives.But perhaps this success left us with a lasting reflex:microbe = enemy.The microbial world tells a much bigger story.Microbes are among the great ecological engineers of our planet. They recycle the dead, drive the carbon and nitrogen cycles, support plant life and participate in

Is Love the Best Medicine?After fifty years of practising medicine, I keep returning to a simple question: can love be considered a medicine?Not a substitute for medicine, certainly. A tablet may treat disease, a procedure may correct a disorder, a hormone may replace what is deficient, and an operation may remove what is harmful. But perhaps medicine itself works best when it is delivered with love.It begins with self-love—not narcissism, but self-respect. When we value ourselves, we have a reason

The Vettiyan’s Paradox: Is There Really Such a Thing as Win-Win?We like to believe that everyone can win. But can they?A Tamil saying attributed to the vettiyan, the man who tends the burning ground, says:செத்ததால் சாகவில்லை, சாகாவிட்டால் செத்து இருப்போம்.“Because others died, we did not die; Had they not died, we would have.”The vettiyan does not cause death, nor does he wish for it. Yet his livelihood, and his family’s survival, depend upon people dying.Now imagine medicine succeeding

Supplements, Supplements, Supplements Everywhere — But Do We Really Need Them?Supplements have become almost unavoidable in modern life. Vitamins, minerals, protein powders, antioxidants, omega-3s, probiotics and herbal products are marketed for better health, energy, immunity, fertility and longevity.But one question deserves to be asked before swallowing the next capsule: do we actually need it?After 50 years in medicine and 40 years in andrology and reproductive sciences, I have never routinely

Semaglutide and its siblings—tirzepatide, retatrutide and newer oral formulations—are transforming the treatment of obesity and metabolic disease. Their success is real. But does extraordinary efficacy risk making us ask too few questions?The SELECT trial demonstrated a 20% reduction in major cardiovascular events in people with overweight or obesity, established cardiovascular disease and no diabetes. FLOW demonstrated substantial kidney protection in people with type 2 diabetes and chronic kidney

Menarche, Menstruation and Menopause: Are We Mistaking Consequences for Physiology?A woman’s reproductive life is marked by three remarkable events: menarche, menstruation and menopause. We accept them as normal and physiological. But what useful purpose does each event itself serve?Puberty establishes reproductive maturity, yet menarche occurs relatively late, after many physical and endocrine changes have already occurred. Could the first menstrual bleed therefore be regarded as a biomarker of

You, Your Friends, and Your Enemies“யாதும் ஊரே; யாவரும் கேளிர்; தீதும் நன்றும் பிறர்தர வாரா.” — கணியன் பூங்குன்றனார், புறநானூறு 192“Every place is our place; everyone is our kin; evil does not come from others.”Yet there is one person we often overlook: ourselves.You are the most important person in your life. You are your own best friend. You can also be your own worst enemy.The same mind that encourages you can also convince you that you cannot. It can recognise opportunity, but also manufacture

2026/08/09

What if gestational diabetes mellitus (GDM) is not created by pregnancy, but is a pre-existing metabolic vulnerability revealed by it?Pregnancy is a metabolic stress test. As gestation progresses, placental hormones increase insulin resistance, maternal weight usually increases, fetal growth accelerates and fetoplacental demands rise. For most women, the pancreas compensates.But what happens when metabolic reserve is already reduced?Pre-existing adiposity, weight gain and other factors may leave

Continuous Glucose Monitoring Helps Control Type 2 Diabetes. Can It Also Help Reverse It?Continuous glucose monitoring (CGM) is rapidly transforming the management of type 2 diabetes. Once largely confined to insulin-treated patients, it is increasingly being used across the broader spectrum of diabetes care. Yet an important clinical question remains unanswered.Does CGM merely improve glycaemic control, or can it actually help reverse type 2 diabetes?In this episode, Professor Pandiyan Natarajan

Drawing upon biology, medicine, philosophy and everyday experience, he invites listeners to reconsider many of

PCOS to PMOS: Are We Renaming the Syndrome Instead of Rethinking It?Few conditions in medicine have undergone as many identity changes as what we currently call Polycystic Ovary Syndrome (PCOS).Since Stein and Leventhal first described the condition in 1935, it has appeared under several names—Sclerocystic Ovaries, Polycystic Ovaries, Hyperthecosis Ovarii, Polycystic Ovary Syndrome, and now, following an international consensus proposal, Polyendocrine Metabolic Ovarian Syndrome (PMOS).The motivation

2026/07/04

Sleep is one of the most fundamental yet most misunderstood biological processes. In modern life, it is often treated as negotiable—something that can be reduced, delayed, or sacrificed in exchange for productivity, entertainment, or work demands. Yet physiology consistently tells a different story: sleep is not passive rest, but active restoration.During sleep, the body enters a highly organised state of repair and recalibration. The brain consolidates memory, strengthens learning pathways, and

Pain Is (Mostly) Your Friend: Why Painkillers (Often) Don’t Fix PainPain is one of the most common reasons people seek medical attention. Yet it may also be one of the most misunderstood.Most of us have been taught to view pain as an enemy—something to be eliminated as quickly as possible. Modern medicine has provided an impressive array of medications capable of reducing or even abolishing pain. While these drugs have transformed countless lives, an important question remains:Are we treating the

Fever Is Not the Disease: Are We Fighting the Wrong Enemy?Few symptoms provoke as much anxiety as fever. A slight rise in body temperature can trigger concern in families, prompt urgent medical consultations, and lead to immediate use of fever-reducing medications. For many people, fever itself is viewed as the illness.But is that perception correct?In this article, I examine a question that is rarely asked in modern healthcare: Is fever really the enemy, or is it part of the body’s solution to

Many countries, including Japan, Italy, South Korea, Germany, and China, now have fertility rates below the replacement level of 2.1 children per woman. As populations age and workforces shrink, concerns are growing about who will support pension systems, provide healthcare, and care for the elderly.Is this a demographic crisis—or a demographic transition
