Abstract A new kind of weight-loss medicine is making waves in medical research — Orforglipron , the first small-molecule, nonpeptide oral GLP-1 receptor agonist. Unlike existing GLP-1 drugs that require injections, this one comes as a pill. In a major phase 3 trial, it showed remarkable success in helping people with obesity lose weight safely and consistently. Orforglipron represents a new era in obesity treatment — an oral GLP-1 receptor agonist that delivers powerful weight-loss results without injections. In clinical trials, it helped participants lose up to 11% of their body weight while improving blood pressure and metabolic health.

Diet and exercise remain the cornerstones of treatment, but for many, they’re not enough. Over the last few years, injectable GLP-1 drugs like semaglutide have helped mi...

Teenage years are meant to be a time of growth, confidence, and self-discovery. But for many Indian boys, this period is clouded by an uncomfortable reality— gynecomastia , commonly called “man boobs.” What was once whispered about in hushed tones is now an increasingly visible concern among adolescents across the country. The four clinical grades of gynecomastia: from minor breast enlargement without excess skin (Grade 1) to significant enlargement with skin excess (Grade 4). Credit: dr-delgado.com This condition is not just a cosmetic issue. It often carries heavy emotional, social, and psychological weight. Let’s break down why more Indian teens are facing this challenge and what can be done. 1. Understanding Gynecomastia Definition : Gynecomastia is the abnormal enlargement of breast tissue in males due to a hormonal imbalance. Not just fat : It is different from pseudogynecomastia, which is fat deposition due to obesity. Gynecomastia involves actual glandular tissue growt...

When you visit a doctor, the common expectation is that they will listen to you—not just hear your words, but truly listen in a way that makes you feel seen, heard, and understood. Yet in today’s fast-paced healthcare environment, this kind of real listening can often be the first casualty. Appointments feel rushed, and providers may barely have time to focus. But what if listening was not just a courtesy or a "nice-to-have" skill, but a vital form of medicine itself? Listening in health care is more than politeness—it’s healing. Researchers describe “values-driven listening,” where curiosity, presence, and compassion lead to stronger trust and better care.  Credit: Shutterstock The Heart of Healing: Values-Driven Listening Dr. Leonard Berry of Texas A&M University's Mays Business School and his colleagues from the Institute for Healthcare Improvement and Henry Ford Health Detroit highlight a concept they call "values-driven listening." This goes beyond me...

Abstract Scientists have long known that obesity increases the risk of Alzheimer’s disease (AD), but how body fat affects the brain has been a mystery. A new 2025 study by Li Yang and colleagues has finally traced the biochemical link—tiny, fat-carrying particles called extracellular vesicles (EVs) may act as molecular couriers between adipose tissue and the brain, altering lipid balance and promoting toxic amyloid build-up. The brain listens to more than thoughts—sometimes even to fat. Photo by Steven HWG on Unsplash 1. The Background Alzheimer’s disease is expected to affect over 82 million people by 2050 . Obesity is a major modifiable risk factor for AD. The brain is rich in lipids, and changes in fat metabolism influence amyloid buildup, inflammation, and neuron death. Until now, the exact molecular bridge between peripheral fat and brain degeneration was unclear. 2. What the Researchers Investigated The study focused on extracellular vesicles (EVs) —micro...

Can a Malaria Drug Transform PCOS Treatment? Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders, affecting up to 13% of women of reproductive age worldwide . Despite its prevalence, the condition remains poorly understood, with treatments that mostly manage symptoms rather than the root cause. Now, a surprising discovery is making headlines: artemisinin , a drug derived from the Artemisia annua plant and widely used against malaria, may also hold the key to managing PCOS. What is PCOS? In polycystic ovarian syndrome, cysts form from follicles holding unreleased eggs (right ovary in this illustration compared with a healthy ovary, left). PCOS affects hundreds of millions of people worldwide, but effective treatments remain elusive.

Symptoms: Irregular or absent ovulation, multiple ovarian follicles , acne...

Playing Minecraft Hints at How We Learn in Real Life Minecraft may be a blocky world filled with zombie piglins, chicken jockeys, and floating pumpkins, but beneath its playful exterior lies surprising insights about how humans learn . Recent research shows that the strategies players use in this virtual world mirror real-world learning—and reveal why humans are exceptional learners . In a world of blocks and hidden treasures, how we explore, adapt, and learn —alone or together—reveals the secrets of human learning. Photo by Oberon Copeland @veryinformed.com on Unsplash Here’s what the study uncovered: 1. Minecraft as a Learning Lab Scientists modified Minecraft to create a controlled experiment where players foraged for hidden rewards like pumpkins and watermelons. Rewards appeared either randomly or in clusters, with clustered rewards offering clues about where to search next. Players competed alone or in groups, creating scenarios for both individual and social learning. ...

The Immune System's Guardians: Meet the 2025 Nobel Laureates Mary E. Brunkow, Fred Ramsdell and Shimon Sakaguchi: Discoverer of  how our bodies prevent the immune system from mistakenly attacking itself. Credit: Nobel The 2025 Nobel Prize in Physiology or Medicine has been awarded to three groundbreaking scientists— Mary E. Brunkow , Fred Ramsdell , and Shimon Sakaguchi —for unveiling one of the immune system ’s most remarkable secrets. Their research has uncovered how our bodies prevent the immune system from mistakenly attacking itself , a discovery that is transforming medicine and offering hope to millions suffering from autoimmune diseases . The Mystery of Self-Tolerance Imagine a fierce army designed to protect a kingdom. But what if that army accidentally turns on its own people? This is what happens when the immune system misfires, attacking the body’s own tissues and causing autoimmune diseases like type 1 diabetes , multiple sclerosis , or rheumatoid arthritis . For y...
