Genome-Wide Association Studies (GWAS) scan the entire genome to pinpoint genetic variations linked to common diseases such as diabetes and hypertension. This overview introduces the key genetic concepts, study designs, and statistical methods that make GWAS possible, while highlighting safeguards against false results. It also explores how GWAS discoveries are being translated into tools like Polygenic Risk Scores, paving the way for more precise and personalized approaches to public health.

Trees quietly draw water from their roots to their highest leaves, lifting it over 100 meters without any visible mechanism. Most of this water evaporates, and only a small amount is used for photosynthesis. For centuries, this process puzzled scientists until the late 19th century, when the Cohesion-Tension (CT) theory explained how evaporation and water molecule cohesion make this possible. Despite this breakthrough, researchers still debate the details: how water moves through roots and nanoscale spaces, how trees survive cavitation and repair themselves, and how climate change could disrupt this balance. Professor Harvey Brown examines these ongoing mysteries in this article.
This analysis examines India’s ambitious Great Nicobar Island (GNI) port project, highlighting its geopolitical objectives that have generated significant concerns. It demonstrates how global power dynamics increasingly hinge on control over maritime trade routes and energy supplies, compelling India to establish a major transshipment hub. The piece also critically examines the project's feasibility, environmental effects, and social impacts. It highlights the geological instability of the selected site, the irreversible harm to a UNESCO biodiversity hotspot, and the displacement of indigenous tribes, raising important questions about the project's economic viability and ethical considerations.

Prologue
When a flowering branch placed in a vase continues to thrive longer than expected, it is often thanks to a florist’s special touch--her secret...
This article takes you on a journey into physics, starting with classical mechanics — the branch that explains how things move and interact. Instead of relying on myths or guesswork, science builds its understanding of the world through evidence and careful observation, and mechanics is a perfect example of that. We’ll explore the basics of kinematics, learning about scalars, vectors, and motion, and even get a first look at powerful math tools like differentiation and integration. But this isn’t just theory — these ideas shape the world around us. From predicting how a ball will fly through the air to guiding satellites in space, Newton’s laws are at work everywhere, powering the GPS systems on our phones and making modern technology possible.
In the quiet before numbers took on meaning, before commerce and code intertwined, there existed only purity --- simple, indivisible truths written into the very fabric of mathematics...
