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 […]

A creeping darkness is settling over the ocean’s photic zone. While the full consequences are not yet clear, scientists say the trend is real and “a genuine cause for concern.” The photic zone is the wonderful in-between world where sunlight provides energy to the ocean before it plunges into absolute darkness. Even at night, the […]

Seals are pretty incredible mammals. Not only do they possess the lung capacity to make epic dives and are caring mothers, but they also survive in some pretty testing conditions. Down deep in the ocean, there is very little light, and the water can be very cloudy, so how are these pinnipeds navigating? One research […]

Water fluoridation has arguably never been a hotter topic in US political and scientific circles. Since first being introduced in Michigan in 1945, the addition of fluoride to public drinking water has been celebrated as a big win for oral health, but has also attracted fierce criticism. Now, with moves being made to ban fluoridation, […]

A Chinese paraglider is thankful to be back on solid ground after unintentionally soaring to an altitude referred to as the “death zone“. Peng Yujiang, 55, was testing out some new equipment on the ground, with no intention of flying, when a strong updraft unexpectedly swept him skywards to a height of more than 8,500 […]

This week, scientists have proposed infecting another world with life to see what happens, we’re starting to understand the ancient Incas’ mysterious string “writing” system, and a patient who received an infected injection nearly 50 years ago has only now suffered the effects of a severe prion disease. Finally, we ask, if the human brain […]

The Oldowan stones are believed to be the oldest known examples of stone tool industry in the world. Their development around 2-3 million years ago represents a significant moment in our evolutionary history as it demonstrates the first evidence of cultural behaviour. But while the stone tools themselves are well known among archaeologists and other […]

Woolly mammoths, Tasmanian tigers, not-really-dire wolves – increasingly, genomics has revealed itself as a major potential player in the quest to revive long-extinct species. But here’s a question: what if we could use it to help avoid the loss of entire species in the first place? Wouldn’t that be, you know, better? According to a […]

SpaceX has had an interesting week. A few days ago, the ninth test of Starship ended up with the vehicle burning in the atmosphere over the Indian Ocean. Yesterday, the company shared a presentation by founder and CEO Elon Musk on their plan for uncrewed and human Mars exploration and settlement. Calling the timeline ambitious […]
