The destruction of Pompeii preserved ash residues on the household altars of its inhabitants. An international research team has scientifically investigated for the first time what was burned in Roman incense burners from Pompeii—and discovered something surprising: In addition
When cells experience enough chronic stress, they can stop dividing permanently. In this state of cellular limbo, known as replicative senescence, cells remain alive but no longer proliferate. Pinpointing the stressors that help trigger or accelerate replicative senescence has
Astronomers have discovered an exceptionally rare radio galaxy that has three distinct pairs of radio lobes. This system falls into a subpopulation of radio galaxies known as "triple-double" radio galaxies (TDRGs). Located nearly 7.5 billion light-years away, this unique
In a study published in The Anatomical Record, researchers have identified a new species of large-bodied gorgonopsian from the middle Permian. The discovery pushed back the known origins of when these apex predators began evolving large bodies and their unique later skull
Volcanoes are both captivating and disastrous. Most are likely familiar with the common short-term dangers associated with them: explosive forces, lava, and even atmospheric particles disrupting air traffic. But researchers also explore longer-term impacts of eruptions, as
Green roofs and green walls are no longer niche design features but proven, scalable nature-based solutions that can significantly enhance biodiversity, climate resilience, energy efficiency and human well-being in European cities. This is a central finding of a new knowledge
The rainforests of northern Australia are home to extraordinary ant colonies. Instead of dwelling in underground burrows, these ants inhabit canopies of trees, dozens of meters above the ground, inside hollow spheres they construct from tree leaves. During the building process,
The people who toiled night and day to put astronauts on the moon during Apollo are thrilled that NASA is finally going back. They just wish these Artemis moonshots had happened sooner while more of Apollo's workforce was still alive.
