Does Exposure to Electromagnetic Fields Modify Brain Waves Permanently?

Is it possible that long-term exposure to electromagnetic fields could eventually change your brain waves, therefore changing the way you think, how you process information, and what sort of chemical splashes your brain delivers based on your observations, studies, reflections, and memory retrieval. Now then, and you must realize this is purely speculation, and my comments come from observations of many individuals over several decades now, so, I have this little personal theory I'd like to share with you along these lines.

You see, I've met many individuals who have worked in places under a constant electromagnetic energy field. Perhaps they worked in a hydroelectric plant, a telephone switching station, in an air traffic control facility, or they work in the communication facilities at a military installation. Now then, before you chock off this theory of mine and throw it into the category of; conspiratorial theories, I'd like to remind you that the brain is actually an electromagnetic organic device.

Biology Review: Proteins and Enzymes

Proteins

Proteins are long chains of amino acids joined by peptide bonds that fold up into complex three-dimensional structures.

The functions of proteins are so diverse and important that almost every function of every living organism depends on proteins.

This helps explain why evolutionary biologists tend to believe that protein synthesis preceded the evolution of the first cells.

In cells, proteins account for about half of the dry mass.

Top 10 Things You Wish You Knew About Butterfly Wings

We tend to admire butterfly wings for their captivating beauty. Our negligence in overlooking other fascinating facts about these wings is therefore quite excusable... but wouldn't you like to know more? Here are our top ten (well, maybe more) facts that you will be excited to learn.

Butterflies Have Scaled Wings

The scientific name for the butterfly/moth family is Lepidoptera. This word is derived from Greek roots meaning "scale wings." For scientists, the most obvious feature that separates butterflies and moths from other insects is their scaled wings. While we may not notice this immediately, closer inspection of a butterfly reveals the fact that their wings are made from tiny scales that are actually bulbous, modified feathers. The pigments of the scales on their wings come either from chemical pigments such as melanin or from plants and waste that build up during metamorphosis. 

Depletion of Biodiversity of Jharkhand State of India

INTRODUCTION:

The term biodiversity was coined by Walter and Rosen in 1985, which is the abbreviated word of Biological Diversity. The biosphere constitutes a vital life support system for man and its existence of human race. The newly formed state Jharkhand of India is very rich in biodiversity due to its diverse physiographic and climatic conditions. The Jharkhand state is situated between 21°58'10" to 25°18' N Latitude and 83°22' to 87°57' E Longitude. Jharkhand forms part of the Chotanagpur plateau province of the Deccan Peninsula Biogeographic Zone. As the name of the state suggests, it is having a good covering of forests (reserved forest 4,387.20 sq km, protected forest 19,184.78 sq km and unclassified forest 33.49 sq km). The forest of the state includes tropical dry deciduous, moist deciduous, dry peninsular and dry mixed deciduous forest. The forests form catchments of the three main rivers - Koel, Damodar and Subernekha. 

A Look Into: Mutations

Contrary to popular media, mutations are not always as great as they are made out to be. They do not constitute to super powers as many would like to believe, although sometimes they provide beneficial traits that can help out a species. For example, an organism may develop a mutation that codes for a certain color that allows it to camouflage from its predators. This will then give the organism a better chance to reproduce and the potential for a resulting new population of its species thanks to its particular trait. Though, most of the time mutations lead to hindrances that affect survival because changes are more likely to cause a problem to the intricate system of nucleotide translation. Mutations result from damage in an organism's DNA. They can occur either spontaneously during DNA replication or through exposure to factors that increase the chances of acquiring mutations, mutagens. An example of a mutagen is the UV light radiation from the sun's rays, which is why you hear that you should not sunbathe constantly because doing so will continuously expose the skin to this type of radiation and can result in a mutation that causes adjacent thymine bases in DNA to dimerize and potentially lead to skin cancer.

Dolphins in Bangladesh

Dolphins are like mammals. They respire through their nostrils. They give birth to new babies and rear them until grownup. Their food items include small fishes, crustaceans, water insects etc. They live mostly in the estuary. Dolphins play an important role in the ecosystem. They can't live in the polluted water. So they indicate the pollution of the rivers. As they eat small fishes so they are also the indicator of fish abundance of that region. River erosion as well as huge numbers of vessel traffic affect their normal life. A great number of dolphins are found in the coastal belt of Bangladesh. The mixing process of freshwater with brackish water and leaves from the mangroves makes a favourable environment for different species of dolphin. The following seven types of dolphins are abundant here-

Ganges river dolphin or Shushuk (Platanista gangetica)

The Ganges River dolphin or shushuk is an "endangered", evolutionary ancient mammal that occurs in many rivers of Bangladesh.
