Bibo, wonderful animated short film about a lonely robot, a year in the making – a sort of modern-day, sadder version of Pixar’s groundbreaking 1986 classic Luxo Jr.

This is beautiful and wonderful and incredibly depressing.

The Astro Alphabet

that holds clusters together, but not me and you!

cast light-blocking shadows that can’t be outrun.

F is for Fusion, that powers the stars,
as nuclei join, their released light is ours!

house billions of planets with lifeforms unknown.

Drug Abuse and Your Body

Drugs impact every organ in the body. In this easy to read graphic, we demonstrate the impact of the most commonly abused drugs on the body’s organs and its systems.

Many people who use drugs, even if they are prescribed, are unaware of how a drug impacts the normal functioning of the body. Whether it is tranquilizers, steroids, or marijuana you can see the organs affected and read about the drug induced changes that occur within each of the body’s systems.

The Galle crater is a Martian crater that happens to look like a smiley face, due to the position of a curved mountain range.
Someone made a good point about our previous post about carbon dioxide melting on Mars. At normal pressure, or the very low atmospheric pressure on Mars (less than 1% of the average at sea level on Earth), dry ice does not melt into liquid. Instead, it sublimes. Sublimation is a word for the phase transition where a solid bypasses liquid entirely and becomes gas. This is what gives the familiar smoke effect you get when you expose dry ice to air. You would need a pressure of over 5 atmospheres, that is five times the pressure at sea level on Earth, or about a thousand times the average pressure on Mars, to create liquid carbon dioxide. Sublimation also occurs to a certain extent to water ice on Earth.
The point at which dry ice sublimates at normal pressure is -56 celsius, which means when the temperature goes below this, the opposite transition, from gas to solid, which is called deposition, occurs. Thus “melts” was not the right word to use in the previous post. This also gives a measure of just what spring on Mars means: the dry ice cover starts melting, sorry, sublimating when the temperature goes above -56.4 C or -69.5 F. Talk about a chilly spring!
The atmosphere on Mars is about 96% carbon dioxide. About 0.1% is oxygen. For comparison, Earth’s atmosphere is about 78% nitrogen and about 21% oxygen.
The somewhat surprising fact, at least to me, that there’s only 21% oxygen in the atmosphere lead to the invention of carbogen, a mixture of oxygen and carbon dioxide. This mixture can be used to simulate the feeling of suffocation without actually suffocating, as the brain does not monitor the oxygen levels in the blood, but rather responds as if you can’t breathe if the blood carbon dioxide levels go too high.

Anyone else find it intriguing that there will be more people over the age of 85 in 2060 than there will be people in their late 70s?

Language and Your Brain

For centuries, researchers have studied the brain to find exactly where mechanisms for producing and interpreting language reside. Theories abound on how humans acquire new languages and how our developing brains learn to process languages.

And here’s a handy GIF about tonight’s the lunar eclipse. For the west coasters (who have a better chance of seeing the eclipse through the clouds) just subtract 3 hours.  It’s basically a moving version of this NASA graphic.
