Biology

 

Biology is a science of three dimensions. The first is the study of each species across all levels of biological organization, molecule to cell to organism to population to ecosystem. The second dimension is the diversity of all species in the biosphere. The third dimension is the history of each species in turn, comprising both its genetic evolution and the environmental change that drove the evolution. Biology, by growing in all three dimensions, is progressing toward unification and will continue to do so.                                                                                                                                                                                                                                                                                                              — Edward O. Wilson

Seasonal Affective Disorder – SAD

The Indian subcontinent lies right above the equator with the tropic of cancer stabbing right through 8 of its states. This localization on the globe, revolution of our planet around the sun and the tilt in the Earth’s axis contribute to the country getting a fair share of all seasons annually. But do these seasons contribute to something other than the scenic beauty and the annual crop yield data?

Bipedalism – Evolution to Modern Day Walking

bipedalism evolutionBipedalism means locomoting (e.g., walking, jogging, running, etc.) on 2 legs. Human anatomy successfully defies the central principles of mechanical engineering. In most manufactured devices, such as cars and ships, the bulk of the weight is concentrated in the lowermost part to achieve maximum stability. But in humans, there is an irregular distribution of mass throughout the body.

Insight on Protein & Muscle Building

Protein supplements have become very popular in the bodybuilding and gyming community. It gives results faster and catalyzes one’s approach towards building a good physique. But too few of these supplements make the process of muscle gain slower, whereas, too many of them invites severe side effects. So, what’s the current amount? Why do we need protein for muscle gain? Let’s try to understand what’s the science behind it

Beat-Boxing and Science

In this modern world of the music industry and passion, an entirely new tread of Beat-Boxing is at a swift rise. In recent years it beat-boxing has evolved to a whole new level. From Beat-Box battles to independent Beat-Boxers on YouTube/on streets, it is no more confined to a trend or talent, it is becoming a culture. At present, there are various communities promoting and evolving beat-boxing all across the world

The Health Language of our Tongue

Surprisingly our tongue shows color variations in a manner such that it is more than the colors in the rainbow. Which means we can ourselves know what is wrong with our body by looking at our tongue up to some extent. Amazing, isn’t it? So, let us try to know the various symptoms your tongue shows regarding various diseases and infections.

Why Do Males Need Females?

Best science starts with simplest quetsions which no one bothered to answer as they seemed too obvious. When mammals reproduce why do they require a male and female parent?

The first thing that strikes out mind is the need to restore normal chromosomal number. But if that’s the only thing then why not 2 eggs or two sperms fuse to give rise to a healthy offsprings?

Hisss…. Venom Kills

When we think of natural selection and evolution, we think of animals chasing each other… competing to be fast and to be strong. For hundreds and millions of years, the world’s top predators have relied on speed, their size, reflexes, biting strength and sensing abilities to overpower their victims. But, venom, shifts the balance of power.

 

Pervading Darkness

Imagine the era when eyes were yet to be evolved,.. animals racing for survival in pitch darkness. With the accumulation of sensory receptors at the anterior end of the general body plan, a rough sketch for certain senses could be guessed. Gradually along the evolutionary tree, we could see the emergence of senses that capture visual data and vibrations (sound). Such senses meant to some animals as a better tool to target and, for others, as a tool to spot (the predator). Animals could now precisely analyze their surroundings and thrive better. However,.. what if an animal was no longer able to see? Having eyes is no good if the animal is not able to resolve the processed image.

The Genomic Dust

When life was in its early stages,  trying every possible conformation, with every possible means available, nature soon figured out a way to perform essential processes in an efficient manner. Nature never aims for perfection.

Changes happen, organisms evolve randomly and the best of the available options is selected,… that too on the basis of the selection pressure applied. Back then, organisms didn’t show much of an interaction.

 

Why Are Flowers Brightly Colored ?

Karl von Frisch, a Nobel Laureate, one of the founding fathers of Ethology, in the second instalment of the series on how to design experiments in animal behaviour asked a question: Why are flowers brightly colored ?
He surmised that flowers must be brightly colored in order to attract honey bees. But this contradicted the work of an authority in visual science, the ophthalmologist C von Hess who concluded on the basis of his own experiments, that all invertebrates including honey bees and even fishes were color blind.

Science behind Goosebumps

If you feel a sudden, uncontrollable chill when you’re afraid, cold or emotional, why do you get goosebumps? Ever thought of that? This is because our biology made it so.
Thousands of years ago, before we were designated homo sapiens, we were once in need of more primitive biological responses to help us deal with outside forces.
So, how exactly do goosebumps work?

Researchers discover how fatal bio-films form

Bull Ant Venom could help develop new Pain Treatments

Venoms of bees and ants had been a subject of research for some decades, but there had been little research on ant venom.” A team of Queensland scientists hopes the venom of giant red bull ants will lead to the discovery of better pain treatments. The ants, an Australian species with a notoriously painful sting, were collected from a colony in Brisbane for the first comprehensive study into their venom.

Resolution of Human Eye- How many Megapixels?

When you see and very beautiful scenery, you take out your phone (or camera) to capture it, isn’t it? But damn! The picture appears to be somewhat different (if you don’t possess a luxurious DSLR). The touch of beauty that appears to our eyes is missing from the picture. Why can’t we capture the exact image we see?

Measles – A Brief Introduction

Everybody is talking about Measles – but what does the virus actually do in the body?Is it really so harmful that you need a vaccination?Let’s go deep into the body of an infected person and see what Measles does and how the immune system reacts to it!

DNA Digital Data Storage

Ever thought how our genetic information is stored in a DNA? Scientists and Researches are bring out work to bring in the concept of Data Storage using DNA. It has been discovered that it be used to store huge amount of data. Think attracted the interest of scientists and researchers.

Sleep-Lack: What Happens To Your Body If You Stop Taking Sleep?

What Happens To Your Body If You Stopped taking Sleep? Lack of sleep may eventually kill you. Here is what happens to your body and brain when you stop sleeping. How much amount sleep do you actually need? What would happen if you didn’t sleep? Why do we need to sleep? How sleep helps your body stay healthy? How sleep deprivation effects your health?

 

Synthesis of Artificial Embryo is a reality now.

 In a breakthrough that redefines how life can be created, embryologists working at the University of Cambridge in the UK have grown realistic-looking mouse embryos using only stem cells. No egg. No sperm. Just cells plucked from another embryo.
