Due to the versatility of gold, its conductivity, durability, and good looks place it firmly in the top five most expensive metals. Gold prices stand at over $1,850 per ounce at the time of publication – impressive, but nothing compared to rhodium. Currently the most expensive precious metal and one of the rarest, the price […]

Fresh evidence suggests that early humans in Europe were mastering fire around 245,000 years ago. If this latest assessment is on point, it indicates our distant relatives may have been sat around a campfire, perhaps sharing food and building social bonds, up to 50,000 years earlier than previously thought.   In a recent study, researchers […]

One of the oldest burial chambers in the Iberian Peninsula has been identified in a cave in northern Spain, with bones from within the pit dated to over 7,000 years ago. Representing some of the earliest Neolithic human remains ever discovered in the region, the find provides a rare insight into the funerary customs of […]

Africa is slowly but surely splitting in two. The east of the continent is scarred by one of the largest rifts in the world. Despite its colossal size, scientists know surprisingly little about the complex movement of this unusual deformation. In a new study, researchers used GPS mapping and computer models to change that.  The […]

Have you ever noticed that when the remains of ancient civilizations are found, they are often dug up or unearthed, and never found “lying around” or “just sort of sat there”? Well before you go assuming the obvious (an order of mole people, dedicated to hiding knowledge of the past) you should know there are […]

The Wizard of Oz got a hat tip from scientists poking around in an ancient and underwater volcano chain in the Pacific Ocean, as they discovered what looked like a “yellow brick road”. The natural brickwork was actually the result of volcanic geology which has fractured the rock in a curiously uniform way. E/V Nautilus […]

In the deserts of the Middle East, you can find vast megastructures known as desert kites that were carved into the rocky landscape over 8,000 years ago. In a recent study, archaeologists have discovered the world’s oldest architectural plans detailing how ancient humans managed to construct these colossal structures. Desert kites were only identified in […]

This week Cherenkov light was observed for the first time during a fusion reaction, changes in the Earth’s orbit may have facilitated a bit of hominin hank-panky between Neanderthals and Denisovans, and scientists simulated black hole recoil speeds for the first time. Finally, we dove into the topic of neurodiversity to explore what it means […]

The star HD 45166 has puzzled astronomers for a century. Dr Tomer Shenar got so fascinated with its existence that he has spent years trying to explain its nature. In the process, he may have solved an even bigger mystery: the source of the universe’s most powerful magnets. HD 45166 is a Wolf-Rayet star. These […]

Aboriginal Australians are the world’s oldest continuous living culture, yet one of their traditional cornerstones of communication – the message stick – is not widely understood today. Nevertheless, it’s a tradition that’s still wielded as a potent symbol of Aboriginal rights. Message sticks are solid pieces of wood of varying length, typically between 10 to […]

A closer look at a collection of cave art in Spain has revealed a number of long-lost animal figures and shapes that haven’t been appreciated for thousands of years. The researchers say their work highlights the importance of how rock art is often a three-dimensional medium that can’t always be understood in a two-dimensional image.  […]

Around 125 million years ago, a small dromaeosaurid dinosaur started moving around the Earth. Not all that surprising given it was the start of the Cretaceous, the last period of the Mesozoic that we know as the “Age Of Dinosaurs” – that is, until you find out it had four wings. And yes, it was […]

If you go down to San Diego today you could be in for a big surprise. Creeping out of holes and cracks in Southern California are two species of tarantula that are setting off for their annual mating ritual. The California black tarantula (Aphonopelma eutylenum) and the San Diego bronze tarantula (Aphonopelmus reversum) are the […]

After two centuries of skyrocketing growth, a significant dip in humanity’s population is “inevitable”, according to a new paper penned by a leading population ecologist. William E Rees, Professor Emeritus at the University of British Columbia, is the author of over 150 peer-reviewed papers on growth and socioeconomic development. Through the course of his decades […]

August 18 marks the anniversary of one of the greatest enduring mysteries of US colonial history: the Lost Colony of Roanoke. While the bizarre incident is often dubbed “America’s oldest unsolved mystery,” we now have a pretty good idea of what occurred (it just took 400 or so years to get a clear idea). In […]

In a small pilot study, scientists have developed a simple oral test that could eventually be a holistic approach to identifying early heart disease risks. There is a strong link between mouth health and heart disease. Gum inflammation can lead to periodontitis, which is a serious gum infection that damages the soft tissue around teeth. […]

A mummified woman discovered over a century ago in Bolivia may have suffered from a fungal infection commonly known as Valley Fever. While the pathogen usually causes non-fatal respiratory systems, in this case, it appears to have destroyed the victim’s bones, possibly leading to her death. Caused by the inhalation of the spores of certain […]

The Sun shapes what goes on in space around our planet. Plasma from our star is continuously thrown at Earth in the form of solar winds or coronal mass ejections, changing the shape of the magnetic field, and affecting the atmosphere and anything in it, like the satellites that we depend on. These changes are […]

The Hirota people, who inhabited a Japanese Island 1,800 years ago, had uniquely shaped skulls – and it was no accident or genetic quirk. A new study, finally confirming what anthropologists have long thought to be true, reveals that this Indigenous group intentionally deformed the skulls of their infant children, although their reasons for doing […]

Sweating milk, ballooning noses, and laying eggs. It doesn’t exactly sound like typical mammalian behavior. Many of us grew up believing the key characteristics were having hair and milk (which, technically, would include coconuts), but science has proven time and time again that there’s a lot more to this group of animals. Join us as […]
