The circulatory system is a vast, complex network of blood vessels that serve as highways for transporting blood which contains life-sustaining molecules, such as nutrients, gasses, hormones and waste products, to the various organs of...

Hawking radiation was first discovered by English scientist Stephen Hawking in 1974. Prior to this discovery, our knowledge of black holes was very limited. It was believed that black holes were completely black and that they did not...

Bose Einstein condensate is considered the fifth state of matter - its obtained when gas particles are cooled to almost absolute zero temperature. To generate the Bose-Einstein condensate, the first step is to obtain a cloud of gas; a...

A Boltzmann brain is not real, but what’s fascinating about it is that it thinks it’s real, and all the memories and experiences it has are real. But, of course, this brain is not real. But how would such a brain know that its...

Bird strike on airplanes is one of the most biggest causes of concern for the airline industry and military. When a bird or a flock of birds hits an airplane, the plane may sustain some serious damage which can have disastrous...

Zebras are actually black with white stripes. All animals get their colors from pigments called melanin which are of two kinds - eumelanin gives a black to brown color which pheomelanin gives reddish to yellow hues. The cells that create...

Coefficient of restitution: What is it? How is it related to the general bounciness of balls and other objects? Here's a quick, simple and basic explanation of the coefficient of restitution for kids and laymen. Basketballs bounce a lot,...

A black hole is a celestial body or simply a place in space where the gravitational pull is so high that nothing, not even light can escape it. This is why it's completely black, and hence it's called a black hole. A black hole's...

Mercury and Venus have no moons because of their close proximity to the Sun. Any moon orbiting around them is likely be swallowed by the mammoth gravitational pull of the mighty Sun. All planets except for Mercury and Venus have moons....

Space is filled with countless stars, all of which radiate enormous amounts of heat. These stars are tens of thousands of times bigger than our own sun. Still, space is considered to be cold. Why is that? If there are so many hot burning...

Experts use veins to draw blood for blood testing, blood donation, and more because the structure and position of veins make it easier to draw blood out of as compared to arteries. It may also be dangerous to draw blood from arteries.

A circle is 360 degrees But have you ever thought why is a circle not a simpler number, like 10 degrees or 100 degrees? As it turns out 360 is actually a very good number. From a purely mathematical standpoint, a number like 10 or 100...

The heart is practically immune to getting cancer. 2 in 100,000 of those who have cancer are those with a primary cancer of the heart. That is an astonishing low number. So, what is so special about the heart that it rarely, if ever,...

Commercial airplanes don't give parachutes to passengers. While airplanes have plenty of safety features that help in landing them safely during emergencies, having parachutes onboard for every passenger doesn't seem like a bad idea,...

Babies are cute because of their face structure and their sounds. Adult brains find the faces features of babies' faces cute. This signature cute baby face is called Kindchenschema (or baby scheme in English). Our brains seemed to be...

Why do we dance? We dance to music because of neural connections in our brain. These connections link the part that perceives music, the auditory cortex to the regions that help us move, the motor regions. We might have started creating...

Heisenbergs uncertainty principle says that if we know everything about where a particle is located, we know nothing about its momentum. Conversely, if we know everything about its momentum, then we know nothing about where the particle...

Lying on the lowest point on the Earth, the hypersaline Dead Sea is one of the most fascinating places on this planet. People float effortlessly here and that is the major attraction of the Dead Sea. But besides this natural buoyancy,...

Planetary orbits are elliptical because gravitational interaction over time changes the delicate balance of mass, velocity and distance from the star which otherwise keeps planetary orbit circular. For a very long time, from Ptolemy to...

Quantum entanglement is a physical resource, like energy, that is possible between quantum systems. When a coin spins on a flat surface, its in a state of superposition between its two faceshead and tails. Similarly, electrons in their...

Fast Food Freddy hypnotizes the entire city with his new creation: The Lazy Hazy. Only Mixie-Bot can save the day with some delicious Energy-Boost Bars. Then get ready to rock with Freezer Burn’s exercise anthem!

Fizzy frantically rushes to get the Lunch Lab ready for the mayor's annual inspection, but now he doesn’t have time for breakfast! The band gets in the holiday spirit with this festive little ditty about eating tasty treats in moderation.

Archimedes principle states that if an object is submerged in a fluid, then the buoyant force acting on it is equal to the weight of the fluid displaced by that object. Buoyant force exists because pressure increases as an object goes...

Remember those old space movies where spaceships had to maneuver through a bunch of asteroids scattered around and blocking the path of the ship? Well, that's not really true. The asteroid belt contains asteroids which are so far apart...
