Earthquakes:Can We Predict Them?

INTRODUCTION  One of the most terrifying natural disasters on Earth is an Earthquake as they strike without warning,shaking cities,destroy the infrastructure and claim lives in a matter of seconds. The question about the prediction of earthquakes repeatedly arises because of its unpredictable nature,from the 2004 devastating Indian Ocean earthquake to the recent tremors felt across Asia. Despite of so many advancements in science and technology,prediction of earthquake remain one of the greatest challenges in modern geophysics.  In this blog post,we will explore about the earthquakes and why their prediction is so unreliable and how close is to science in making the prediction of earthquakes more reliable. Sup CAUSES OF EARTHQUAKES  Before prediction, we must first understand about the earthquakes.  The outer layer of the Earth is known as lithosphere which is divided into large slabs known as tectonic plates. These plates are in constant motion,althoug...

The Story Of Our Genes: Epigenetics

INTRODUCTION  During the period of twentieth century,the field of biology was dominated by the simple and powerful idea:our genes determine who we are. It is believed that at the time of our birth—eye color,height,disease risk and even some aspects of our behavior are hardwired into our DNA. The crucial role of genetics in shaping our life cannot be denied but modern biology has revealed a far more dynamic picture. The fascinating field of epigenetics which shows how our genes are not fixed instructions but flexible scripts that respond to our environment, lifestyle and experiences. The understanding of scientists about human development,disease, health and inheritance is greatly influenced by epigenetics. This field has explained why identical twins become different over a period of time,how stress can leave biological scars and how diet and environment can influence not only our lives but also those of future generations.  Sup WHAT IS EPIGENETICS ? ...

Symphony of Wildlife

INTRODUCTION  On your next vacation in mountains,walk down into the forest lane at dawn or sit calmly near a lake in the evening,then you'll realize something extraordinary and fascinating—a world alive with movement,sound,rhythm and purpose. This hidden symphony of wildlife was in existence long before humans learned to build civilization,and its still continues its ancient melody even today but now this inheritance is on the verge of extinction. The bright wings of butterflies which flutter over the wildflowers, echoing calls of whales across the ocean,all the wildlife beings adds richness,balance and meaning to our planet. Even before we could understand the impact,most of these creatures are disappearing at a faster rate than we could imagine. In this blog post,we will explore the magical world of wildlife,its importance and how we as individuals can play a role in protecting it. Sup A WORLD OF FASCINATING DIVERSITY  The planet Earth is a habitat ...

Promoting Greener Future by using Renewable Energy

INTRODUCTION  Over a century,the progress of the world has been powered by coal,oil and gas—the energy sources which fuel industries,built cities and connect the globe. But everything comes with a cost, the progress made by industries, urban cities led to the emissions of carbon,global warming and ecological destruction.  Nowadays, as changes in climate is on peak,the world stands at a turning point. The question arises that we should switch to renewable energy or not,the answer lies in the fact that how fast can we make this transition because it is essential to shift towards renewable energy sources. From using fossil fuels to cleaner energy sources like solar,wind and hydropower is necessary for revolutionizing and reshaping our economies,communities and future. Sup In this blog post,we'll explore some of the cleaner energy sources along with the importance of transition towards them. As we know that everything comes with challenges too,so innovative ideas are...

The Layers of the Atmosphere

INTRODUCTION  A complex and dynamic system which plays an essential role in supporting life on our planet is the atmosphere of the Earth.  This atmosphere is divided into different layers,each possessing it's own unique characteristics and functions.  In this blog post, we will explore the different layers of the atmosphere and their importance.  The Five Main Layers of the Atmosphere  Earth's atmosphere is divided into five distinct layers which are as follows: 1) Troposphere  2) Stratosphere  3) Mesosphere 4) Thermosphere 5) Exosphere Let's discuss all the five main layers in detail. 1) Troposphere :  It is the lowest layer of the Earth's atmosphere and it extends from the surface upto about 12 kilometers (7.5 miles) high. This layer is where weather occurs and is characterized by decreasing temperature with altitude.  ● Characteristics of the Troposphere  • Temperature :  The temperature in this layer decr...

Unveiling the Life Threatening Disease:AIDS/HIV

INTRODUCTION  The conditions which can significantly impact an individual's quality of life and may lead to severe health complications or even death are known as life threatening diseases. Such diseases can be acute or chronic, infectious or non-communicable and can affect anyone regardless of age,gender or background. It is important to understand such life threatening diseases so that we can either prevent them or detect them early so that the disease can be managed effectively which ultimately improves the outcomes and save lives. In this blog post,we will discuss one such life threatening disease which is AIDS(Acquired Immune Deficiency Syndrome), it is a chronic and a potentially life threatening disease that is caused by the Human Immunodeficiency Virus (HIV). This virus attacks the immune system of the body thus making it difficult to fight off infections and diseases. We will also discuss its transmission,symptoms, treatment options and the importance of awaren...
