Earth’s crust is made up of fractured slabs of rock, like a broken shell on an egg. These plates move around at speeds of about 5cm per year – and eventually this movement brings all the continents together and form what is known as a supercontinent. The last supercontinent on Earth was Pangaea, which existed between 300-180m years ago.

Genetic analysis reveals new evidence to explain how the hogfish uses its skin to “see.”The hogfish is a pointy-snouted reef fish that can go from pearly white to mottled brown to reddish in a matter of milliseconds as it adjusts to shifting conditions on the ocean floor.

If you go down to the shore today, you’re sure of a big surprise. Many will have witnessed the presence of a starfish or two when visiting the seashore or a public aquarium. Starfish come in an exciting range of colours and sizes, but have you ever given a thought to how this multi-armed wonder manages to exist in our oceans when it’s so unlike the other animals we know?

What do birds and aerospace engineers have in common? Both have invented incredibly dark, “super-black” surfaces that absorb almost every last bit of light that strikes them.

Years ago, we believed that we weren’t animals and that animals were here solely for our use. Indeed, a cow was just a walking burger, steak of Sunday roast, keeping itself fresh and tasty ready for when we were hungry.

Humans have built high-rises since ancient Roman times, but it wasn’t until the 20th century that they became the default work space for a significant slice of the world’s workers. While these buildings are certainly efficient, they can cause real health issues.

“The oceans cover 70% of the surface of our planet, and yet they are still the least explored,” says Sir David Attenborough in the opening sequence of the recent BBC documentary series Blue Planet II. “Hidden beneath the waves, there are creatures beyond our imagination.” Yet while the programme reveals the wonders of many of these species, an incredible number more have never been encountered by humans at all.

Slowly but steadily, an enormous mass of warm rock is rising beneath part of New England. But don’t worry—a major volcanic eruption isn’t likely for millions of years.

Beneath the Antarctic ice sheet, there lies a continent that is covered by rivers and lakes, the largest of which is the size of Lake Erie. Over the course of a regular year, the ice sheet melts and refreezes, causing the lakes and rivers to periodically fill and drain rapidly from the melt water. This process makes it easier for Antarctica’s frozen surface to slide around, and to rise and fall in some places by as much as 6 meters (20 feet).

Sixty-six million years ago, an asteroid struck Earth in what is now the Yucatan Peninsula in southern Mexico. This event, known as the Chicxulub asteroid impact, measured 9 km in diameter and caused extreme global cooling and drought. This led to a mass extinction, which not only claimed the lives of the dinosaurs, but also wiped outabout 75% of all land and sea animals on Earth.

Coconuts have been a valued food in tropical areas for thousands of years, traditionally enjoyed as coconut water from the centre of the coconut, coconut flesh, or coconut “milk” (made by steeping the flesh in hot water).

Until recently, anthropologists drew the human family tree in the same way that my 10-year-old son solves a maze. He finds it much easier to work from the end to the beginning, because blind alleys lead with depressing sameness away from the start. In just this way, scientists once traced our own lineage from the present into the past, moving backward through a thicket of fossil relatives, each perched upon its own special branch to extinction.

Once upon a time, fireflies were abundant throughout Japan. For more than 1,000 years, these glowing harbingers of summer shone brilliantly through the fabric of Japanese culture, which celebrated them in poetry and art.

Few places on earth are as well known for their so-called mysteries as Easter Island, also known as Rapa Nui. For a tiny island of 64 square miles, with its nearest neighbours some 1,300 miles away, it has seen more than its fair share of controversy.

Strong, rapid wing beats with hardly any push off let mosquitoes make a fast getaway. The technique is in stark contrast to other insects, like flies, that push off first and then start beating their wings frantically, often tumbling uncontrollably in the process. That strong push off also lets us know they’re there before they have a chance to escape.
