Clues within ancient animal poop challenge the current prevailing theory that humans tamed plants before beasts. Researchers found the preserved dung in question alongside buried remains of ancient hunter-gatherer dwellings in Syria that date back to around 13,000 years ago. “We were surprised when we realized that hunter-gatherers were bringing live animals to Abu Hureyra

On Earth, shifts in our climate have caused glaciers to advance and recede throughout our geological history (known as glacial and inter-glacial periods). The movement of these glaciers has carved features on the surface, including U-shaped valleys, hanging valleys, and fjords. These features are missing on Mars, leading scientists to conclude that any glaciers on

Hundreds of millions of years ago, a carnivorous critter gorged on a feast of prehistoric amphibians – and puked up its meal afterward. Now, paleontologists have unearthed the regurgitation and published their findings of the ancient upchuck. In 2018, researchers discovered the regurgitalite – fossilized remains of an animal’s stomach contents, also known as a

A core principle of Einstein’s general theory of relativity has just passed its most stringent test yet. Using a specially designed satellite, an international team of scientists measured the accelerations of pairs of free-falling objects in Earth’s orbit. Results based on five months’ worth of data indicated the accelerations didn’t differ by more than one

Australia’s crafty, sulphur-crested cockatoos (Cacatua galerita) appear to have entered an “innovation arms race” with humans, scientists say, as the two species spar over the rubbish in roadside bins. ​The white birds, which can grow nearly as long as a human arm, initially surprised researchers by devising an ingenious technique to prise open household bin

Korea’s ‘artificial Sun’ reactor has made headlines this week by officially sustaining plasma at a temperature of 100 million degrees Celsius for more than 20 seconds. The team at the Korea Superconducting Tokamak Advanced Research (KSTAR) device reached an ion temperature of above 100 million degrees Celsius (180 million degrees Fahrenheit). According to New Scientist,

Failing to achieve the Paris agreement goal of limiting global warming to 1.5 °C could trigger multiple dangerous “tipping points” where changes to climate systems become self-sustaining, according to a major new study published in Science. Even current levels of warming have already put the world at risk of five major tipping points – including

Once containing a vast, prehistoric ocean, the Nullarbor Plain in southern Australia is an extraordinary landscape. Now a scrubby desert on limestone bedrock, it’s extremely flat and almost featureless, extending for over a thousand kilometers. But a new discovery suggests that the vast, semi-arid expanse may not be as featureless as we thought. Using satellite
