Dental hygiene has come a long way over the past few hundred millennia. While most of us now automatically brush our teeth twice a day, ancient humans had a much harder time looking after their pearly whites. Sadly for our long-in-the-tooth ancestors, many of their archaic dental practices appear to have been ineffective, leading to […]

After more than a decade of development, the first human trial for a treatment that attempts to tackle end-stage liver disease (ESLD) by turning lymph nodes into livers has begun. “In a medical first, we have now dosed our first patient in a clinical trial using their own lymph nodes as living bioreactors to regenerate […]

Against all odds, a millennia-old variety of the Greek language has managed to survive into the 21st century. However, researchers are now warning that it could be the last chance to save this “linguistic goldmine” from extinction. Romeyka is spoken by just a few thousand native speakers living in the mountainous villages of northeastern Turkey’s […]

To mark the 140th anniversary of the SS Tasman’s sinking in Tasmanian waters, a group of three divers decided to visit the shipwreck. Despite the technical challenges of getting to the boat, the team were pleased to see not only the wreck remains on the sea floor, but also catch a glimpse of a critically […]

On Earth, flames are shaped by gravity. Hot gases from the flames rise while gravity pulls cooler and denser air downwards to the bottom of the flame, giving it its familiar teardrop shape.  In microgravity environments – such as on the International Space Station (ISS) – this cycle does not take place, and the result […]

Eclipse fever is mounting, but it might deflate like a flan in a cupboard for some. The path of totality stretches from the west coast of Mexico all the way to Newfoundland. Millions already live on the path of totality, with many more expected to travel to the relatively thin – at most 200 kilometers […]

A detailed study of the richest haul of Paleolithic wooden tools has provided unmatched insight into the lifestyles of Neanderthals living a little over 300,000 years ago in what is now northern Germany. Hominins have been using stone tools for at least 3 million years, and probably noticed wood could do some useful things about […]

After the record-breaking summer of revealed dead bodies in 2022, and historically low waters that have seen the Colorado River’s connection with the sea severed, Lake Mead seems to still be suffering the effects of climate change and population growth which has seen its water levels rapidly decrease over the past few years. Lake Mead […]

We could soon be catching criminals using an entirely different kind of DNA sampling approach that tests for evidence in the air. Forensic-savvy criminals may know to wipe down the scene if they want to get rid of damning DNA evidence – but both the air itself and air conditioner units can still hold incriminating […]

Welcome to the wonderful world of thunder eggs. They might look plain from the outside, but can be cut and polished to reveal a whole range of colors and crystals within, and are popular with the rock collecting community.  Thunder eggs, also known as lithophysae, are spherical objects formed in silica-rich volcanic rock, often a […]

A lot of cool things are going to happen when the Moon obscures the Sun on Monday. If you are in the path of totality, which extends from Mexico to Canada, this celestial encounter will bring a few minutes of darkness to your day. Your eyes will obviously be on the sky but they will […]

A six-legged mouse embryo, with extra limbs in place of genitals, has been engineered by scientists. It sounds like sci-fi, we know – but the curious creature, which also has several of its internal organs outside of its body, wasn’t created intentionally. Rather, it was an unprecedented outcome of research that has, in turn, revealed […]

The temperature at which a material melts, subject to pressure, follows a single parabolic equation, one scientist has claimed, providing a surprisingly simple solution to a long-standing problem. If you want to turn a solid to liquid the usual approach is to add heat. However, the temperature at which melting occurs depends not only on […]

The Namib desert is named for what it is: “an area where there is nothing,” in the local Nàmá language. And at first glance, the region lives up to the title, covering around 1,600 kilometers (990 miles) along the western coast of Africa – straddling three countries as it does so – in some of […]

Throughout the ups and downs of Earth’s climatic history, forests have moved in response to changing environmental conditions. As glaciers retreated after the last Ice Age, trees swooped in to fulfill the freed-up real estate, but climate change in the modern era is happening too rapidly for their shifts to keep up.  Enter, the DREAM […]

At first glance, this might just look like strangely symmetrical rock. However, researchers have recently taken a deeper look at the object and speculate that it may be a prehistoric sand sculpture of a stingray. If that’s true, it would make the relic the oldest known artwork of another animal.  It was discovered in 2018 […]

Prisoners held in New York are attempting to sue the state’s corrections department over a decision to lock all inmates indoors during the total solar eclipse on April 8. Ahead of the eclipse, Jeremy Zielinski, a prisoner held at Woodbourne Correctional Facility, was granted permission to view the eclipse, after he argued that the event […]

Tidal locking is such a common phenomenon in the universe that we only need to look at the Moon to notice it. Our satellite only shows us its near side face as its rotation on its axis and revolution around the Earth are synchronized. Planets too can get in this state of behavior if they […]

A person in Texas has tested positive for H5N1 bird flu after coming into contact with dairy cows that are presumed to be infected with the virus. Fortunately, the patient is recovering and their only reported symptom was red eyes, according to the US Centers for Disease Control and Prevention (CDC). They’ve been told to […]

The ancient hominin Australopithecus anamensis is thought to be one of our oldest known relations – but what do we actually know about the species? How long ago did they live? Though arguably not the most famous of the australopiths – that title probably goes to A. afarensis, thanks to Lucy – A. anamensis is estimated […]
