This video brings to life the evolution of aggresive behavior in a population, and its relation to game theory – the field of mathematics concerned with quantifying strategic behavior and decision-making. The author illustrates what happens in an artificial population of species that exhibit two entirely different strategies as they compete for resources. In the first strategy called ‘dove’, organisms are required to share their food source with the other if both happen to land at the same site after being randomly shuffled. Sharing your food source allows the organism to survive another cycle, but not reproduce, unless they’re fortunate enough to land at a site all by them self. The author shows that if this cooperative strategy is ...

A defining features of learning mathematics is being able to read, write, and discover proofs. A proof is a method of communicating a mathematical truth to another person who speaks the "language" of mathematics. It's a way of showing whether a statement made is absolutely true or false.

I recently came across a fallacious proof attempting to show that the integer one equals two – shown are the steps to accomplish this. Common sense dictates that this is impossible, but the proof is somewhat convincing to the untrained eye. However, most people with basic algebraic knowledge should be able to pick out the mistake, so take a minute or two to see if you can identify the incorrect step. If you're stuck, don't give up so quickly! It's easier th ...

Different bird species have distinct calls that they recognize and pay attention to. Play the compilation video below and see if you can recognize any of the bird sounds; these birds are specific to North America. 


The first six birds have familiar calls, the next six displays birds that are widespread across North America, and the final set has some trickier birds. If you think that you're an expert or know of someone who is, have them play the video blindfolded - you'll be interested to see how they respond!

The video below shows 16 hours of neural development compressed into 40 seconds of a developing zebrafish's nervous system. Notice how the neurons branch to make connections with other neurons – a process vital to information transmission.

To obtain such accurate footage, the animal's embryo was suspended in water, rather than gel, and its photographers used gentle light sheet technology to capture the specimen in 3D, at a high temporal resolution.

The thylacine (Thylacinus cynocephalus) was the largest known carnivorous marsupial of modern times. Due to its striped lower back, it is commonly known as the Tasmanian tiger. Native to continental Australia, Tasmania and New Guinea, it is believed to have become extinct in the 20th century. It was the last extant member of its family, Thylacinidae; specimens of other members of the family have been found in the fossil record dating back to the late Oligocene.

Surviving evidence suggests that it was a relatively shy, nocturnal creature with the general appearance of a medium-to-large-size dog, except for its stiff tail and abdominal pouch (reminiscent of a kangaroo) and dark transverse stripes that radiated from the top of its back, simil ...

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.

To tap into scarce water supplies, most desert plants have extensive root systems that burrow deep or spread wide. But one desert moss has a different trick up its sleeve: a thirst-quenching structure called an awn. Awns are tiny, hairlike structures that project from the end of each leaf to capture water (above). For the first time, scientists have examined in detail how this moss (Syntrichia caninervis) pulls water right from the air using its awns. At the smallest scale, the awns are covered with grooves about 100 nanometers deep and 200 nanometers wide, the perfect size for dew to condense within them when conditions are right. Those nanogrooves lie within larger troughs that measure about 1.5 micrometers deep and 3 micrometers wide, a ...

After a broken neck left him quadriplegic, Ian Burkhart was told he would never be able to use his hands. Now he can grasp a bottle and pick up a credit card by using a computer plugged directly into his brain. Special software is able to decode his thoughts and convert them into electrical signals in his hand, bypassing the damaged nerves in his spine. Now Ian has regained an amazing degree of control over his hand, each movement stimulated by his own thoughts.

Here's what happens when you pour 1 984°F/1 085°C molten copper on a Big Mac. This demonstration has nothing to do with the fact that McDonald's uses preservatives in its ingredients. This is simply a demonstration of the Leidenfrost effect - a scientific principle explaining the phenomena that occurs when a liquid comes in near contact with a solid that is significantly hotter than its boiling point; the surface of the liquid comes to a nearly immediate boil, and creates a thin layer of protective steam. It's much the same effect as when one drops water onto a hot pan and the droplet is seen to dance across the surface. In this instance, the inherent moisture in the burger protects it for a few moments before the copper (at nearly 2 000 d ...

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, ...

The blue-capped cordon-bleu (Uraeginthus cyanocephalus) has a special talent. Not only can it sing, it can shake a leg or two. For its courtship display, it holds a piece of nesting material in its beak, points its head upward, moves up and down, and sings. Both males and females bob and sing like this, and choose their partner. Now, researchers have found that as the bird bobs, it does a quick tap dance where it stomps its feet.

Nitrogen triiodide (NI3) is a contact explosive that sets off whether it comes in contact with a feather or a bug. As shown in the diagram, the chemical is made up of a cluster of three iodine atoms around one side of a nitrogen atom. The result of such a crowd around one atom causes something called bond strain - the atoms repel each other in a small space. The result of this bond strain is that the molecule is prone to falling apart very, causing the mini explosion you see ().

Start by watching the video below In the video, a Japanese man converts plastic waste into usable oil and fuel using a machine that thermochemically decomposes the plastic in a process known as pyrolysis.



Pyrolysis works by thermochemically breaking down material at temperatures above 350 degrees Celsius in the absence of water. This not only physically melts down an object, but also changes its chemical composition so that, in the case of plastic waste, it reverts back into boiling liquid and eventually gas.

There are two different "thinking" systems that predominate our brain. They are responsible for our first impressions and then later changing them, our in depth views and perspectives, in addition modulating our thinking with respect to a given context. System one is mainly the "fast" thinking system. System two is a relatively slower thinking system. Their remarkably different yet crucial functions are portrayed beautifully in this video.

The Chernobyl disaster of 1986 was one of the worst man-made disasters of the 20th century. An explosion and fire released large quantities of radioactive particles into the atmosphere, which spread over much of the western USSR and Europe. During the accident itself, 31 people died, and long-term effects such as cancers and deformities are still being accounted for.

An abandoned ferris wheel and buildings reclaimed by nature - the remains of the 1986 Chernobyl disaster show what a city looks like when everyone disappears.

A restaurant in Japan has created a new dish where the squid comes “back to life” and “dances” on your plate. The dish is called Odori don. Basically the dish is a rice bowl topped with a whole fresh squid (minus the head). When soy sauce is poured on the squid, a chemical reaction occurs that causes the squid’s tentacles to squirm around in the bowl, making the squid appear as if it is dancing a jig!
