Basic Volcano Facts 1. Volcanoes are […]

How fruits and veggies looked like before we domesticated them

Imagine a banana. The familiar yellow, seedless shape pops to mind, but that’s only how domesticated bananas look like. Before we “molded” and modified the plant, it looked completely different – as you can see below.   The first bananas we know of were cultivated in Papua New Guinea, stocky and filled with seeds. By […]

The geometry of a Pringle

Mathematics is not about equations, numbers, computation or algorithms: It is about Understanding! There are many ways to understand it – the one that this post is based on is real life visualization. The Pringle shape is what is known in mathematics / calculus as a hyperbolic paraboloid. Why are Pringles a hyperbolic paraboloid? The […]

The Iron Snail lives on volcanic vents, two miles under the sea, all thanks to its spectacular armor

It's hard to believe anything can be alive thousands of feet below the Indian Ocean where thermal vents effectively boil the water. Yet even in the most inhospitable conditions, life has a way of creeping in. Such is the case of chrysomallon squamiferum, a snail-like creature which may very well sport the best armor in the animal kingdom.

'Fire Rainbows' - What they are, how they form, and of course, great pictures

With the recent sighting of a fire rainbow in South Carolina, there seems to be a sudden surge of interest for this phenomenon, so I thought I’d come back with some more information. First of all, they’re not ‘fire rainbows’; in fact, they’re not rainbows at all. The correct name is circumhorizontal arc, and it’s […]

The Skypunch - not a fancy anime combat move, but just as awesome

This rare flower's petals are usually white, but turn translucent (their "skeleton" form) when exposed to water. Being completely clear and of striking, glass-like beauty while wet, they turn white again when they dry off.

Domes of ice and grass: the Pingos [with great pics]

Also called hydrolaccoliths, pingos are spectacular domes of earth and vegetation covered ice usually found in the Arctic and subarctic. They can reach up to 90 metres (300 feet) high and more than 800 metres (0.5 mile) across and are usually circular or oval-shaped. They may be green on the outside, but the core is solid, clear ice.

They did the math - things you won't believe people on the internet calculated

Every once in a while, you stumble upon a statement or question so preposterous that you don’t even bother thinking  about it – but somewhere, someone on the internet did the math. This is a list of that kind of things – crazy things that someone actually calculated. This is not real science though, so […]

If you fold an A4 sheet of paper 103 times its thickness will roughly be the size of the Universe

Whaaaat? It’s just a matter of math, really. Fold an A4 once and it will be twice as thick, fold it again and it will be four times as thick as it initially was. Turns out, according to Dr Karl Kruszelnicki, if you do this 103 times the sheet’s thickness will be larger than the observable Universe: […]

How would the world look like without ice?

There are more than five million cubic miles of ice on Earth, and throughout our planet’s history, there have been periods with both more, and less ice. We tend to think of ice as an immovable reality but in truth, planetary ice is quite volatile. With continuously rising temperatures, melting ice and rising sea levels […]

The Mind Bending Types of Geological Folds

Folds are some of the most common geological phenomena you see in the world – a geological fold occurs when planar (usually sedimentary) layers are curved and/or bent, permanently deformed due to outside pressure. Folds’ sizes can vary from microscopic to mountain-sized, as you can see above. Despite being a fairly simple process (in principle), […]

Why some tropical mushrooms glow in the dark

The tropical forests of Northeaster Brazil have their own nightlight: a peculiar mushroom called Neonothopanus gardneri that glows in the dark. Like a street light, it's tuned to activate its bioluminescence only in the dark, first in the twilight then peaking at about 10 PM. Researchers at Dartmouth College in the US and the University of São Paulo in Brazil have now fond out what this strange behavior is all about: 'candy' for insects.

Watch: The surprising chemical reaction between Coke and Milk

Watch the video all to the end – it starts off a bit slow, but it gets pretty rad towards the end. I’m not sure what I was expecting to happen… but it clearly wasn’t this: So what’s happening here? Well, it’s plain to see that a bunch of dark particles precipitate at the bottom […]

Places on Earth that actually look like Hell

The orange molten rocks beneath Kamchatka’s volcanic landscape looks surreally out of this world. It looks like a gateway to hell, or even yet, like Mordor. The Kamchatka peninsula, located in eastern Russia, is riddled with 160 volcanoes, including 29 active ones. The highest volcano is Klyuchevskaya Sopka (4,750 m or 15,584 ft), the largest active volcano in the […]

The Heaviest Living Organism in the World

What is the heaviest living creature in the world? It’s not an elephant or a blue whale, the heaviest organism is actually an Aspen. Pando, as it is called, is a clonal colony of a single male quaking aspen; basically, it looks like more trees, but it’s actually just one living creature with one massive underground […]

The largest organism in the world

If you want to know what the biggest organism in the world is, then you’re in for a big surprise – it’s not an elephant or a tree, it’s not even a blue whale! It’s 2 miles across, and you don’t even see most of it – because it’s a mushroom. That’s right, the largest living […]

Doggerland -- the land that connected Europe and the UK 8000 years ago

We all know that Earth used to look very different in the geological past, but few would imagine that Europe was such a different place just 8,000 years ago. Back then, continental Europe was connected to the UK with a land mass called Doggerland. The area had a thriving history both for wildlife or for […]

So, we’ve already discussed about the largest and heaviest organisms in the world, now it’s time to see what the world’s oldest animal is – spoiler alert, this one is also a surprise. If you’re thinking it’s a turtle or an elephant… you’re way off. If you think it’s a whale, you’re a bit closer, […]

What gives coffee its distinctive color and flavor?

Coffee beans undergo several processes before they become the delicious brew we all know. The coffee beans we’re used to seeing, the brown ones with a delightful flavor, are roasted. Raw coffee beans have a different color and smell very differently. So what makes roasted coffee look, smell, and taste so different from raw coffee? The […]

How fire burns in zero gravity

In space, of course, you can't have any fires because there isn't any oxidizer (i.e. oxygen) to sustain the combustion process. Inside a spacecraft or in the International Space Station, however, things are a bit different. Inside you have the same air mixture as on Earth, but because gravity is millions of times smaller an open flame behaves significantly different.

Penguins are amazing creatures, living in some of the harshest conditions in the world. They have an extremely sociable behavior for birds, they have big egos, busy sex lives, and they also commit suicide. We don’t know why this happens. Sometimes, some penguins just head on to the middle of the icy desert, far away […]

The blanket octopus is truly a remarkable creature. It exhibits extreme sexual dimorphism – while the males are only a few centimeters long, the females grow up to a whopping 2 meters. Unfortunately, they’re rarely seen and studied, so there’s still some mystery about the evolution of this dimorphism, but it’s known that males have […]
