World Mosquito Day
August 20, 2013 in the World
World Mosquito Day takes place on August 20, 2013. World Mosquito Day is a commemoration of British doctor Sir Ronald Ross’s discovery in 1897 that female mosquitoes transmit malaria between humans. Ross is responsible for the annual observance, having declared shortly after his discovery that the day should be known as World Mosquito Day in the future. The London School of Hygiene & Tropical Medicine holds Mosquito Day celebrations every year, including events such as parties and exhibitions, a tradition dating back to as early as the 1930s.
Although a few species are harmless or even useful to humanity, most mosquitos are a nuisance because they consume blood from living vertebrates, including humans. The females of many species of mosquitoes are blood-eating pests. In feeding on blood, some of them transmit extremely harmful human and livestock diseases, such as malaria, yellow fever and filariasis. Some authorities argue accordingly that mosquitoes are the most dangerous animals on Earth.
Various species of mosquitoes are estimated to transmit various types of disease to more than 700 million people annually in Africa, South America, Central America, Mexico, Russia, and much of Asia, with millions of resultant deaths. At least two million people annually die of these diseases, and the morbidity rates are many times higher still.
Methods used to prevent the spread of disease, or to protect individuals in areas where disease is endemic, include: Vector control aimed at mosquito control or eradication;
Disease prevention, using prophylactic drugs and developing vaccines; Prevention of mosquito bites, with insecticides, nets, and repellents. Since most such diseases are carried by “elderly” female mosquitoes, some scientists have suggested focusing on these to avoid the evolution of resistance.

Radio Day
August 20, 2013 in the USA
National Radio Day celebrates a great invention and communications medium.
The invention of the radio dates back to the late 1800s. A number of inventors played a role in creating this important medium. A number of inventions and discoveries were required to make the radio a reality. This included both transmission and reception methods and technology. The radio somewhat evolved from the telegraph and the telephone, with wireless telegraph directly contributing to its invention.
Celebrating National Radio Day is easy listening. Simply tune into your favorite radio stations(s). You could also give your local radio personalities a little recognition.

August Full Moon
August 20, 2013 in Eastcoast
On August 20, 2013 the moon reaches its maximum brightness. Therefore it is called full moon. Full moon is a lunar phase that occurs when the Moon is on the opposite side of the Earth from the Sun. More precisely, a full moon occurs when the geocentric apparent longitudes of the Sun and Moon differ by 180 degrees; the Moon is then in opposition with the Sun. As seen from Earth, the hemisphere of the Moon that is facing the earth is almost fully illuminated by the Sun and appears round. Only during a full moon is the opposite hemisphere of the Moon, which is not visible from Earth, completely unilluminated.
The time interval between similar lunar phases is on average about 29.53 days. Therefore, in those lunar calendars in which each month begins on the new moon, the full moon falls on either the 14th or 15th of the lunar month. Because lunar months have a whole number of days, lunar months may be either 29 or 30 days long.
Full Moons are traditionally associated with temporal insomnia, insanity and various “magical phenomena” such as lycanthropy. Psychologists, however, have found that there is no strong evidence for effects on human behavior around the time of a full moon. They find that studies are generally not consistent, with some showing a positive effect and others showing a negative effect. In one instance, the British Medical Journal published two studies on dog bite admission to hospitals in England and Australia. The study of the Bradford Royal Infirmary found that dog bites were twice as common during a full moon, whereas the study conducted by the public hospitals in Australia found that they were less likely. Full moons trigger deer movement in North America. Hunters and fisherman rely heavily on moonphases.
