NASA astronauts on board the International Space Station (ISS) have shared spectacular images they took of lightning below them on Earth. Orbiting the Earth on the ISS, astronauts get an unusual view of just about any large-scale phenomenon occurring below, from red sprites to “space angels” and the aurora borealis. In the latest slew of […]

The US is sitting on a largely untapped energy source that could significantly boost its electricity supply, according to a new report from the US Geological Survey (USGS). The study examines the potential of geothermal energy – the natural heat simmering beneath the Earth’s surface – as a major power source. While the US already […]

The southern tip of Africa is slowly lifting out of the water by up to 2 millimeters each year. Now, scientists think they’ve finally figured out why. GPS devices in South Africa have long hinted that something unusual might be happening to the landmass. These instruments can determine both their horizontal position and elevation with […]

Ever been out for a walk and noticed a pair of sneakers dangling from a power line? It’s a surprisingly common sight, and there’s a reason behind it. Shoe tossing – also known as ‘shoefiti’ – happens all around the world, and for a variety of reasons. Let’s explore some of the most common theories […]

It’s a well-known (and somewhat awkward) fact that Homo sapiens and Neanderthals interbred. While previous research has explored when these encounters took place, findings have revealed where exactly it happened. Scientists took a close look at the geographical distribution of both species in Southwest Asia and Southeast Europe around the time we know they hooked […]

In a plot straight out of pretty much any Dan Brown book, ancient sketches by Leonardo da Vinci have revealed the location of secret tunnels underneath a medieval castle in Milan, Italy. In the 15th century CE, Francesco Sforza, Duke of Milan, ordered a fortification be built on the remains of one built in the […]

Did you know that flies hate cocaine? These well-adapted creatures have evolved to avoid things that might do them harm by developing a distaste for bitter things. Knock out those receptors, however, and it’s a very different story as they, just like humans, become really rather partial to a spot of cocaine. Drosophila, a kind […]

Ever wondered why you never see great white sharks in aquariums? It can’t be their size alone, we keep orcas in captivity. So what makes great whites different? The great white shark (Carcharodon carcharias) is one of the ocean’s most powerful and iconic apex predators, known for its massive size, serrated teeth, and a reputation […]

Whether on the playground, in the boardroom, or at formal events, the suit and tie have long symbolized professionalism and style. But it might be time to reconsider the tie. A 2018 study published in the journal Neuroradiology suggests that wearing a tie can restrict blood flow to the brain, potentially causing headaches, dizziness, and […]

“Come on little one,” John Hammond croons to a baby Velociraptor in Jurassic Park. It enters the world all pathetic and gooey, like all good baby animals do, but what do we actually know about dinosaur reproduction? Were there lots of eggs, or just a few in each clutch? How did they stay warm? And […]

We might know scarily little about what lies within our oceans, but one thing we have learnt is that it appears to be absolutely chocka with freaky-looking little weirdos – and cookiecutter sharks are the perfect example. This strange group of sea critters consists of two species: the smalltooth cookiecutter shark, often shortened to just […]

The very first people to set foot in South America belonged to a previously unknown group of hunter-gatherers that later disappeared without a trace, a new study suggests. Initially crossing the land bridge from Central America to northern Colombia some 6,000 years ago, this enigmatic population is completely unrelated to any South American community that […]

A performance of Austrian composer Johann Strauss II’s The Blue Danube was beamed into space for an unusual audience over the weekend. The waltz, composed in 1866, was recorded by the Vienna Symphony Orchestra before being sent over 24.9 billion kilometers (15.5 billion miles) to NASA’s Voyager 1 spacecraft. If you’re a sci-fi fan, you […]

Conservation projects can be tough, often in extreme conditions, against all odds, and even with species right on the brink of extinction. However, they can also be extremely successful, with protected areas and laws leading population numbers to bounce back. One area where this is happening is Blue Spring State Park in Florida, now home […]

The Milky Way and Andromeda are traveling towards each other; this is a fact that we have known for a long time. Over the decades, estimates of the speed and simulations have suggested that the two were going to collide within 5 billion years. But new research argues quite the opposite. A team found that […]

Take a look at any satellite image of Scotland and you’ll hopefully see a giant scar running diagonally through its upper reaches from northeast to southwest. It’s a colossal reminder that very few things on planet Earth ever remain unchanged – including its seemingly sturdy landmasses. This gigantic geological feature is known as the Great […]

Astronomers are puzzled after detecting an unusual, repeating long-period transient (LPT) signal emitted deep in the Galactic Plane. Last year, a team from Australia’s national science agency, CSIRO, found the strange signal using the ASKAP radio telescope on Wajarri Country in Australia. The object, known as ASKAP J1832-0911, appears to emit a pulse of radio […]

If you look up into the clear night sky in the Northern Hemisphere, you will see the star Polaris, more commonly known as the North Star.  Sitting around 1 degree away from the geographic North Pole, this helpfully bright star has been used in navigation (of the Northern Hemisphere) for centuries. In the Southern Hemisphere, […]

Take a quick peek down at your hands. Are your nails green? If so, there are a couple of possibilities: either you’re rocking a funky verdant manicure, in which case you’d probably remember that; or, it’s the much less pleasant option of green nail syndrome. What causes green nail syndrome? Technically known as chloronychia, and […]

The difference between a million and a billion is pretty difficult to wrap your head around. Sure, in one sense it is simply adding on a few zeroes at the end of a number, but when you compare the two numbers by looking at real-world objects the difference is pretty stark. For classic example, a […]
