Centipede Eats Snake

It seems a female nose-horned viper snake tried to eat a centipede. It got the centipede down its throat …. but the centipede fought back!!!

The centipede began to eat its way out of the snake, eventually killing the snake! The centipede almost succeeded in attaining freedom, breaking free from the snake’s body, when the snake’s venom finally killed it. Learn more here.

How do we smell?

April 14, 2014

An adult human can distinguish up to 10,000 odors. You use your nose to figure out what to eat, what to buy and even when it’s time to take a shower. But how do the molecules in the air get translated into smells in your brain?

Slow Life is Amazing

April 2, 2014

“Slow” marine animals show their secret life under high magnification. Corals and sponges are very mobile creatures, but their motion is only detectable at different time scales compared to ours and requires time lapses to be seen. These animals build coral reefs and play crucial roles in the biosphere, yet we know almost nothing about their daily lives.

An enormous water python has devoured a metre-long fresh water crocodile following an epic duel!

The fight began in the water – the crocodile was trying to hold its head out of the water at one time, and the snake was constricting it. After the crocodile had died, the snake uncoiled itself, came around to the front, and started to eat the crocodile, face-first.

What percentage of your brain do you use?

February 13, 2014

Two thirds of the population believes a myth that has been propagated for over a century: that we use only 10% of our brains. Hardly! Our neuron-dense brains have evolved to use the least amount of energy while carrying the most information possible — a feat that requires the entire brain.

The world’s most brazenly hidden bird

February 7, 2014

The incredible common potoo isn’t much to look at — so much so that you’ll struggle to see it at all! In a bold display of camouflage and mimicry, this bird pretends to be a broken tree branch. To do so, it poses absolutely still, bravely evading predators in plain view of them.

The Slingshot Spider

January 21, 2014

Check out this video of a peculiar ray spider doing something very strange. It’s using its web as a slingshot! This aggressive behavior enables the spider to capture insects, like mosquitos, that have developed strategies for not getting caught in a web.

How do cancer cells behave differently from healthy ones?

January 18, 2014

How do cancer cells grow? How does chemotherapy fight cancer (and cause negative side effects)? The answers lie in cell division.

What happens if I swallow chewing gum?

January 5, 2014

So what actually happens when you swallow chewing gum?

The big answer is nothing really. As you chew you absorb all the sugars and flavouring. If you swallow, the chewing gum just passes through your digestive system and quite literally poops out the other end. Lovely.

Caterpillar’s Bad Breath Scares Off Predators

January 2, 2014

The key to the hornworm’s (Manduca sexta) bad breath is nicotine, a toxin it ingests while eating its favorite meal of tobacco leaves. New experiments show that the hornworm repurposes the nicotine, moving it from the gut to the hemolymph, the fluid that fills its circulatory system. The hornworm then excretes this excess nicotine when it exhales.

Tobacco Hornworm

Wolf spiders and other predators that eat the hornworm don’t have its defenses against nicotine and find the breath repulsive—and potentially poisonous! Learn more here or here.
