  Australia is a country within Oceania, the smallest continent on Earth. It is the 6th largest country, the largest island and often considered as the largest island continent. The country consists of a mainland territory, Tasmania, and many offshore islands. Surrounding the continent are the Indian and Pacific Oceans. Australia is indeed a distinctive continent with different climatic conditions and biomes across the country. On the mainland are found the deserts of Australia (also called the Great Australian Deserts). Collectively, these deserts are the 4th largest in the world coming after Antarctic, Arctic, and Sahara deserts. In this article, we shall have a good glance at the physics underlying formation of the desert climate. We shall see how oceanic water currents, air flows and heat transfer across the globe affect the climate of the mainland country. Due to harsh conditions, the deserts are largely void of human settlements and activities although there is evidence that ...

Since the begining of the documentation of medical knowledge, scientists have seen many incredible and astonishing scenarios and situations. Several of these has undoubtedly seems to shifted the frontiers of medical doctrines, principles and knowledge. As it appears, people have defied medical science which has led structural modifications in our understanding of medicine even continuing till today. Many of these extraordinary conditions have therefore largely contributed to our understanding of the human evolution, anatomy, and physiology. While trying to keep the article as short as possible I will discuss several interesting general medical facts and record-breaking events in medicine that have made some people superhumans. Only information specific about humans is considered here  General Anatomy and Physiology • Hydrogen makes >60% of the elemental composition of the body, almost present in all biomolecules. The total number of bones in the adult human body is 206 • Largest...

In what happens to be a shocking announcement, Svante Pääbo, a Swedish scientist was solely awarded the prestigious Nobel prize in physiology or medicine in 2022. This is in recognition of his groundbreaking achievements in founding the field of paleogenomics. Pääbo, a specialist in evolutionary genomics and anthropology has contributed tremendously to our knowledge of the genetic ties between Neanderthals and modern humans through rigorous experiments and has "provided the basis for exploring what makes us uniquely human". Likewise outstanding is his discovery of a novel species of humans called the Denisovans using modern genomic techniques. In this article, we shall get to know about this genius and the implications of his research in physiology. Meet Svante Pääbo The new Nobel laureate in Physiology or Medicine, Svante Pääbo.

There is much excitement among the scientific community as to who will be awarded the Nobel prize in the sciences. I am far more excited. In this article, we shall examine how the understanding of animal behaviour and patterns at both individual and social levels can contribute to our comprehension of human psychology and disease states. This was the subject of the Nobel prize in Physiology or Medicine in 1973 awarded to Nikolaas Tinbergen, Karl Von Frisch and Konrad Lorenz. In this article, we shall realize the mechanism and purpose of the waggle dance which is used by foraging bees to communicate with one another about the location of food sources. Meet the Nobel laureate Nobel laureate Karl Von Frisch. photo credit: Lot-Art Karl Von Frisch, a German-Austrian can be described as a pioneer melittologist who critically and deeply investigated the behaviour of insects, especially honeybees species. He was particularly curious about the mechanism through which bees disseminate informatio...

🔏The most hazardous dust to inhale: asbestos. One of the upshots of the industrial revolution is the construction of modern houses. One of the useful materials which were found to be very valuable and versatile was asbestos. Asbestos is known for its good insulating properties. It is heat resistant, durable, insoluble in acid, stable in air, and very workable. Indeed it was so  that it was spun into yarn and used to make cloth. This article portrays the science of asbestos and how this remarkable substance amassed an awful reputation. Asbestos materials are extremely poisonous. They are known to cause devastating diseases. Photo courtesy: istockphoto. 🔏Asbestos has been responsible for thousands of fatalities and contributed to cases of lung cancer. Asbestos has been recognized since antiquity. Its properties have been described in long past. There is knowledge that it has been used in making items such as earthenware in ancient times. Aggressive mining of asbestos ensued in the ...

 🔐 Charles Darwin's Origin of species  explains how survival instincts are acquired through adaptations and conveyed to generations by learning or by genetic transmission. Everyday life in the wild is a continual struggle to survive and remain in existence. Plants and animals have through time evolved to defend themselves against herbivory or predation. The predator-prey relationship is a perpetually dynamic one. Both kinds endlessly develop tactics and schemes by which they must survive. For example, if a predator discovers a strategy demonstrated by the prey, the predator modifies its tactics to overcome the challenge. In this article, we shall review mechanisms developed by preys that enable them to survive through time.  In the constant struggle for survival between predators and prey, prey has evolved traits and mechanisms to avoid being devoured. These behaviours include visual information-transmission techniques (such as camouflaging, cryptic and colour display, s...
