Bioluminescence

Bioluminescence is one of the most astonishing natural phenomenons as it seems to be drawn from science fiction or comic books, rather than science and natural history. Where else to you find characters with green lanterns, or shooting red beams of light, or escaping with a flash of blue light. How can a living animal make light? The technical answer is that light is produced by energy released from chemical reactions occurring inside (or ejected by) an organism.

One would think that this capability would be rare in nature, yet in the ocean most types of animals — ranging from bacteria to sharks — include bioluminescent members. In fact, it is estimated that luminescence has evolved independently at least 40 times. The functions of bioluminescence are not known for all animals, but typically it is used during ecological interactions for defense (warning or evading predators) or offense (luring or detecting prey), and at times for communication between members of the same species.

Nanotechnology and its Benefits

Nanotechnology is the understanding and control of matter at dimensions between 1 and 100 nanometers, where single phenomenon enables novel applications. Surrounding nanoscale science, engineering, and technology, nanotechnology involves imaging, measuring, modeling, and manipulating matter at this length scale.

A nanometer is one-billionth of a meter. A sheet of paper is about 100,000 nanometers thick; a single gold atom is about a third or a nanometer in diameter. Dimensions between approximately 1 and 100 nanometers are known as the nanoscale. Unusual physical, chemical, and biological properties can emerge in materials at the nanoscale. These properties may differ in important ways from the properties of bulk materials and single atoms or molecules.

The power of nanotechnology is rooted in its potential to transform and revolutionize multiple technology and industry sectors, including aerospace, agriculture, biotechnology, homeland security and national defense, energy, environmental improvement, information technology, medicine, and transportation. Discovery in some of these areas has advanced to the point where it is now possible to identify applications that will impact the world we live in.

Types of medicine

Ayurveda
Ayurveda is that knowledge of life, which deals elaborately and at length with conditions beneficial or otherwise to the humanity, and, to factors conducive to the happiness, or responsible for misery or sorrow besides indicating measures for healthful living for full span of life.

Yoga
Yoga is a science as well an art of healthy living physically, mentally, morally and spiritually. It’s systematic growth from his animal level to the normalcy, from there to the divinity, ultimately. It’s no way limited by race, age, sex, religion, cast or creed and can be practiced by those who seek an education on better living and those who want to have a more meaningful life.

Naturopathy
Naturopathy or Nature Cure believes that all the diseases arise due to accumulation of morbid matter in the body and if scope is given for its removal, it provides cure or relief. For treatment it primarily stresses on correcting all the factors involved and allowing the body to recover itself. The five main modalities of treatment are air, water, heat, mud and space.

Homeopathy
Homeopathy has been practiced in India for more than a century and a half. It has blended so well into the roots and traditions of the country that it has been recognised as one of the National Systems of Medicine and plays an important role in providing health care to a large number of people.

Unani
Unani postulates that the body contains a self-preservative power, which strives to restore any disturbance within the limits prescribed by the constitution or State of the individual. The physician merely aims to help and develop rather than supersede or impede the action of this power.

Siddha
Siddha is very similar to Ayurveda. In the Siddha system, chemistry had been found well developed into a science auxiliary to medicine and alchemy. It was found useful in the preparation of medicine as well as in transmutation of basic metals into gold.

Acupressure
Acupressure is the application of pressure or localized massage to specific sites on the body to control symptoms such as pain or nausea. It is derived from traditional Chinese medicine, which is a form of treatment for pain that involves pressure on particular points in the body knows as “acupressure points”. A practitioner puts pressure on specific points on the body with his or her fingers in order to relieve pain and discomfort, prevent tension-related ailments, and promote good health.

Acupuncture
Acupuncture is an ancient Chinese form of medicine, which involves the insertion of pins in certain vital points of the body. It is used for the treatment of chronic pain conditions such as arthritis, bursitis, headache, athletic injuries, and posttraumatic and post surgical pain.

Telemedicine
Telemedicine generally refers to the use of communication and information technologies for the delivery of clinical care. It may be as simple as two health professionals discussing a case over the telephone, or as complex as using satellite technology and video-conferencing equipment to conduct a real-time consultation between medical specialists in two different countries.
