A mysterious sticky substance found in ancient bronze jars in southern Italy has finally been identified as honey, solving a 70-year-old archaeological puzzle. The discovery, detailed in a study published by the Journal of the American Chemical Society, sheds new light on the ritual and everyday uses of honey in classical antiquity. The residue was originally excavated in 1954 from …

IN A NUTSHELL 🦕 Researchers discovered 80-million-year-old fossils in Brazil, highlighting the presence of osteomyelitis in sauropod dinosaurs. 🔍 Advanced analysis techniques revealed distinct lesions on the bones, providing insights into the disease’s progression. 🌿 Environmental factors, such as arid climates and stagnant water, likely facilitated the spread of the infection. 📚 The findings enhance our understanding of dinosaur health …

Smacking a planet-threatening asteroid comes with big responsibility. If we slam an impactor into an asteroid in exactly the wrong spot, the space rock may pass through a “gravitational keyhole” that actually brings it to Earth — which is exactly what planetary defense scientists and mission planners don’t want to happen. The keyhole is an area in space where the …

Eating lots of meat and drinking sugary fizzy drinks speeds up the onset of dementia and other chronic illnesses, a major 15-year study has found. Scientists tracked nearly 2,500 older adults and discovered that those with the unhealthiest diets – high in red and processed meat, such as bacon and burgers, and carbonated drinks – developed brain and heart conditions …

Liquid water flowed across the surface of the asteroid that birthed the near-Earth object (NEO) Ryugu much later than scientists had thought possible, a new study finds. The discovery that water existed in liquid form a billion years after the parent body of Ryugu formed came from the study of rock samples collected from the NEO by Japan’s Hayabusa2 probe …

For the first time, researchers have uncovered a giant anomalous Hall effect in a nonmagnetic material, rewriting established physics and hinting at novel device possibilities. Credit: SciTechDaily.com Their results pave the way for developing advanced electronic devices that rely on nonmagnetic materials. For the first time, researchers in Japan have detected a giant anomalous Hall effect (AHE) in a material …

New research shows that the presence of dust can cause the tops of clouds—such as these seen over the Sahara Desert—to freeze more easily. Credit: Diego Villanueva/ETH Zürich. Dust plays a major role in the formation of ice in the atmosphere. A new analysis of satellite data, published in Science, shows that dust can cause a cloud’s water droplets to freeze at …

In the 2006 disaster film Poseidon, a luxury cruise ship is capsized by a towering rogue wave, leaving its passengers to fight for survival. While Hollywood often exaggerates, massive and extremely dangerous rogue waves are very real.  These walls of water, often rising more than twice the height of surrounding seas, can strike without warning, swallowing ships whole and crippling …

When the potentially hazardous asteroid 99942 Apophis makes its breathtakingly close flyby of Earth on April 13, 2029, more than 2 billion people across Africa and Western Europe will be able to watch it drift across the night sky. Under clear skies, the space rock will appear as a faint star — about as bright as the stars in the …

Scientists have developed the first-ever time crystals that are visible to the human eye, and they could one day make their way onto $100 bills. The time crystals emerge from the kinks that appear when light is shone onto liquid crystals — the same as those found inside LCD screens . Unlike previous time crystals, these “psychedelic tiger stripes” are …
