Watch this 1940's Disney Cartoon Made to Fight Malaria
|
view preview
In 1943, Walt Disney helped combat malaria by making an animated film called The Winged Scourge. This short film starred the seven dwarfs and taught children that mosquitoes transmit malaria, which is a very bad disease. While not specifically mentioned in the film, malaria is caused by several species of the protozoan Plasmodium, of which Plasmodium vivax and Plasmodium falciparum are the most common. The most serious infections involve P. falciparum, which causes a higher incidence of complications and death. The short film advocated the killing of mosquitoes to stop the disease. Luckily, by 1951, malaria was finally eliminated in the United States ( eliminated means that no new cases arose in the country for 3 years). Today, oral chloroqui ...

Watch how the ancient Babylonians tracked Jupiter in the sky
|
view preview
It's hard to fathom the difficulties our ancestors had to contend with given how our world has advanced with technological sophistication over the past century. We shouldn't, however, underestimate the power of the human-mind, and how everything that was discovered in the past paved the way for the practices used today, especially those used in science. Of the very first astronomers, the ancient Babylonian were the first to use simple arithmetic to predict the positions of celestial bodies. Evidence reveals that these astronomers, working several centuries B.C.E., also employed sophisticated geometric methods that foreshadow the development of calculus. Historians had thought such techniques did not emerge until more than 1400 years later, ...

Tricking your brain into thinking you're in a room full of sunlight
|
view preview
There’s an innovative new light technology that's trying to change the way people think about "artificial light." In Italian company called CoeLux has developed a new light source that recreates the look of sunlight through a skylight so well that it can trick both human brains and cameras. It’s a high tech LED skylight that’s designed to provide "sunlight" for interior spaces cut off from the outdoors. One of the main ideas behind it is that to create realistic sunlight, you can’t just simulate the sun… you need to recreate the atmosphere as well. The scientists who invented the light figured out how to use a thin coating of nanoparticles to accurately simulate sunlight through Earth’s atmosphere and the effect known as Rayleigh scattering ...

The Myers-Briggs test might just be a phony afterall
|
view preview
Could the most widely used personality questionnaire simply be a farce? In case you don't know, the Myers-Briggs test is an assessment test believed by many to measure psychological preferences in how they perceive things and help them in making decisions. According to the Myers-Briggs test, there exist sixteen different types of personalities. This Myers Briggs Test has a series of questions that require your answers, which in turn determine the type of personality you have and provides you with general assumptions concerning how your personality type best suits you. Back in year-3 of my undergrad., I had to spend $20 to take the test for an assignment I had to write. While it was interesting to note how my personality could be read throug ...

The ghost fish has been captured on video for the first time
|
view preview
A living, swimming ghost fish has been seen live for the first time ever. The fish, part of the family Aphyonidae, was caught on camera during an ongoing National Oceanic and Atmospheric Administration (NOAA) exploration by the ship Okeanos Explorer. The exploration centers on the deep ocean at Mariana Trench Marine National Monument, a protected area spanning 95,216 square miles (246,608 square kilometers) east of the Philippines. The secretive fish was swimming along a ridge 8,202 feet (2,500 meters) down, according to NOAA. The animal is about 4 inches (10 centimeters) long, with translucent, scale-less skin and eerie, colorless eyes. No fish in the family Aphyonidae has ever been seen alive before. ...
