In this ten minute clip, Dr. Tyson enumerates a list and then elaborates on each item in a very amusing manner.

Skip between 1:15 and about 2:00 when there are some audio problems and nothing of interest occurs.

Have you heard of a Prince Rupert's Drop? No, it's not the latest dance craze, nor is it the next evolution of an infamous piercing.

Drop a blob of molten glass into a bucket of cold water and it forms into the shape of a tadpole as it cools. This formation is called a Prince Rupert's Drop or "Dutch tear."

If you hit a Prince Rupert's Drop as hard as you can, it will not break. In fact, even if the strongest man in the world had a good bash at it, this glass shape will remain intact. However, chip even the smallest part of the tail off and the whole thing will shatter into tiny pieces.

This is because the bucket of cold water cools the surface of the drop so quickly that the inside is still molten when the outside is solid. When the inside begins to cool, it pulls in and contracts the outside surrounding it, which strengthens the whole structure. Well, all except for the tail, which is too thin to have layers and becomes the structure's weakest point.

The sudden explosion of glass happens so quickly that the only way to capture it for human eyes to see is to play it in slow motion at 130,000 frames per second. That's exactly what this video below from the YouTube channel SmarterEveryDay shows.

Novae is a movie about an astronomical event that occurs during the last evolutionary stages of a massive star's life, whose dramatic and catastrophic death is marked by one final titanic explosion called supernova.
By only using an aquarium, ink and water, this film is also an attempt to represent the giant with the small without any computed generated imagery.
As a tribute to Kubrick or Nolan's filmography, Novae is a cosmic poem that want to introduce the viewer to the nebulae's infinite beauty.

While we just had one in October and there's another one in December, the supermoon coming this month is extra special because it "becomes full within about two hours of perigee - arguably making it an extra-super moon," NASA said.

In a creative stroke inspired by Hollywood wizardry, scientists have designed a simple way to observe how bacteria move as they become impervious to drugs. The experiments are thought to provide the first large-scale glimpse of the maneuvers of bacteria as they encounter increasingly higher doses of antibiotics and adapt to survive-and thrive-in them.

Harvard University selected XVIVO to develop an animation that would take their cellular biology students on a journey through the microscopic world of a cell, illustrating mechanisms that allow a white blood cell to sense its surroundings and respond to an external stimulus. This award winning piece was the first topic in a series of animations XVIVO is creating for Harvard's educational website BioVisions at Harvard.

Have you ever been listening to a great piece of music and felt a chill run up your spine? Or goosebumps tickle your arms and shoulders? The experience is called frisson (pronounced free-sawn), a French term meaning "aesthetic chills," and it feels like waves of pleasure running all over your skin. Some researchers have even dubbed it a 'skin orgasm.'
