Hate winter? Scientists believe they've found the protein that causes winter-specific depression, a psychological condition known as seasonal affective disorder (SAD). According to study conducted by the University of Copenhagan in Denmark, people who develop SAD have less access to serotonin, the brain signalling compound associated with feelings of well-being and happiness, as the days get shorter in the winter months. This is because their brains ramp up the production of a transporter protein called serotonin transporter, which transports serotonin into the nerve cells where it’s not active.

Meet the pistol shrimp. It is known to be the loudest animal and can emit a sound up to 200 decibels which it uses to stun its prey using its pincers. Check out the video below:

This is the spectacular Leafy Seadragon. Its dangling skin disguises the vulnerable species as floating seaweed. Like seahorses, the male Leafy Seadragon carries the eggs, which are bright pink when the female first deposits them, but turn purple or orange when they're ready to hatch after nine weeks.

Seagulls are able to drink seawater to survive thanks to salt glands just above their eyes. These glands eliminate excess salt from the seawater and flush it out of the birds' nostrils in liquid form, an action that's often mistaken for a sneeze.

Meet the ribbon seal, native to the icy waters off the southern coast of Russia. With no confirmed predators (except humans who occasionally hunt them), these seals are known for being super relaxed, and will let you walk right up to them on the ice floes.

This prawn-like, deep-sea creature lives at a depth of 7 km and measures more than 25 cm in length.

Before you watch the video (or read the explanation underneath), try answering the question: What causes the seasons on Earth?. You'll be surprised that even the brightest minds – many of whom have been educated at one of the world's leading universities – can have the same misconceptions as everyone else.


Many believe that the Earth's orbit is an exaggerated ellipse, as pointed out by the narrator. Although the Earth’s orbit is elliptical, it is so close to round that Earth’s distance from the Sun does not vary enough to affect the seasons. In fact, its orbit is only 1.7 percentage points from being perfectly round.

Indeed, Earth is closest to the Sun each year on January 4, when it is winter and cold in the Northern Hemisphere. The seasons ...

1 out of every 50-100 million lobsters has split coloring. One side is typically a dark brown, while the other side is blue, orange, or red. These individuals usually exhibit traits of both males and females.
