Every year,Diwali or Deepawali is celebrated with great pomp not only in India,but around the world. As per the nomenclature,Diwali or Deepawali means an array of brilliantly burning earthen oil lamps whose luminescence dissipates the darkness of the night.  Since the atmosphere is highly contaminated due to the presence of dead bodies of night flies,the flies which keep on rotating and encircling around the lamps,the earthen lamps when burnt release soot or carbon black which is a very nice absorbing agent. It absorbs all the polluted gases and makes the environment clean. Unlike the high temperature of summer heat,the low temperature of cold winter doesn't evaporate stagnant water bodies easily. Hence,they end up becoming breeding ground for insects,especially mosquitoes,which then leads to spread of several contaminated diseases.  The Hindus,who were already experts in the sciences of yoga and ayurveda,thousands of years ago itself,had all the relevant knowledge back then

What an intriguing question ! Believe  it or not,men can actually lactate. Possessing all the necessary equipment,the main reasons men don't have it happen very often,is mostly just a lack of sufficient amounts of a single necessary hormone.  Milk is produced in small hollow cavities in breast tissue called alveoli,where the linings contain cells that secrete milk when properly triggered. While there are a variety of things that go into someone lactating,including various hormones,the main trigger for milk production is sufficient amounts of the hormone,prolactin,which is primarily produced by the pituitary gland,though,also produced by the prostrate gland in men and a layer of the uterine wall known as myometrium in women,among other places. Both men and women have alveoli,but typically different levels of prolactin. A normal non - pregnant woman has around one third to twice the hormone than the average man at any given time. Late in pregnancy and after giving birth,prolact

Looking after your heart means taking small,but meaningful actions - eating a balanced diet,undertaking regular exercise,reducing alcohol intake,quitting smoking...all the things that not only make you healthier but also helping you to enjoy your life to the fullest. Cardiovascular disease is the leading cause of death. World Heart Day plays a crucial role in changing all this. Its a vital global platform that many people from the world can use to raise awareness and encourage individuals,families,communities and governments to take action now. Risk factors that may lead to heart disease and stroke are: 1. Raised blood pressure,cholesterol and glucose levels. 2. Smoking 3. Inadequate intake of fruits and vegetables. 4. Obesity The one organ in our body which gives us the real meaning of being alive is our heart. People can at times be brain dead yet alive. The majority of deaths are a result of coronary heart disease or stroke - that's more than victims of cancer,HIV,AIDS

Mosquitoes are some of the most deadly creatures on the Earth. They carry viruses,bacteria and parasites,which they transmit through bites,infecting millions of people. Currently,control of the diseases such as Zika virus and Dengue virus is mostly limited to broad - based insecticide sprays,which can harm both humans and non - target animals and insects. What if there's a way to control these devastating diseases without the environmental problems of widespread insecticide use? GM mosquitoes to prevent diseases may sound like science fiction,but the technology had advanced recently to such an extent that there is no longer a scenario related to late - night movies. Today,GM mosquitoes,developed during the past several decades of extensive research in various famous universities,are being used to combat mosquito - borne pathogens,including viruses such as Dengue and Zika,in many places around the world. Progress is also being made to use GM mosquitoes to combat malaria,the m

See,vaccines involve needles. Since childhood,many people have needle phobia. Even thinking about them sends those people a spiraling into a private hell inside their mind,while their body gives way to symptoms like heart palpitations and even fainting. Years of knowing about their extreme reactions had left me wondering: Where do such phobias come from? And could people ever get over them? Some people are even terrified of doctors,hospitals and medical exams. Some of their fears go hand in hand with their mistrust of medicine and faith in alternative treatments like herbs and reflexology. Some argue countless times for treatments of things like acid reflux,by applying mustard seeds or applying pressure to the bottom of their foot. Though,people have still managed to rebel against these beliefs,the familial fears have been held on tight,so much that I have pondered whether the phobias could actually be genetic. Some researchers also took and analysed samples of a few people's D

There's always one in a crowd,a sort of harbinger of the oncoming mosquito bite,a person, mosquitoes seem to target more than others. What is it about these unlucky chosen few that makes them mosquito magnets?  Mosquitoes are stimulated by numerous factors when seeking out a blood meal. Initially,they are attracted by the carbon dioxide we exhale. Body heat is probably important too,but once the mosquito gets closer,it would respond to the smell of a potent blood source skin. There are upto 400 chemical compounds on the skin that could play a role in attracting or perhaps,repulsing mosquitoes. This smelly mix,produced by bacteria living in our skin and exuded in sweat,varies from person to person and is likely to explain why there is a substantial variation in how many mosquitoes we attract. Genetics probably plays a big role in this,but a little of it may be down to diet or physiology. Sweat contains lactic acid,which is a key mosquito attractant, particularly for human - bit

Being tall may get you a spot on the basketball team,and it may even be good for your self esteem. But I don't think being tall actually helps. Why? Towering over your peers may also affect various aspects of your physical health,as well..  Recently,researchers also investigated the link between height and venous thromboembolism.They also found that men shorter than 5'3" had a 65% lower risk of developing a venous thromboembolism,which is basically a type of blood clot that starts in the vein,than men taller than 6'2". Well why does this happen? Gravity may be influencing the link. It could just be that because taller individuals have longer leg veins,there could just be more surface area for the problems to occur. Increased gravitational pressure in the veins of taller legs can also increase the risk of slow blood flow or even stop the blood flow temporarily. Being tall may be a marker of over - nutrition - specifically eating too many high calorie proteins.
