Bones

New research on a pterosaur fossil reveals secrets of the creature’s life, including microscopic inner structures of its bones and traces of its biology and diet. The findings show that molecular evidence can survive for more than 100 million years.

An experiment conducted by a team of researchers from Texas A&M University has revealed a healing sequence in mammalian physiology that rebuilds lost skeletal structure, albeit with less than perfect results.

For more than a century, biologists assumed that the bony plates found in the skin of lizards – nature's chain mail – were an ancient feature that some lineages inherited and others later lost. But new evidence suggests this is entirely wrong.

Tea and coffee are two of the most popular drinks in the world – daily rituals that are linked to culture, comfort, and productivity. Now scientists have new insights into how each affects bone health, especially the risk of osteoporosis.

Dinosaurs may be long extinct, but 2025 made it clear that they’re anything but settled science. New fossils, reanalyses of famous specimens and increasingly sophisticated tools have helped us learn more about how they lived, moved, fed and evolved.

Our fat tissue could be used to make our bones regrow, with scientists successfully using adipose cells to repair spinal compression fractures. It could change how breaks are treated and improve bone strength in diseases such as osteoporosis.

Strong bones need more than workouts; they need less sitting. A sweeping review shows that across all ages, even light daily activity protects bone health, while too much sedentary time quietly raises the risk of fractures.

A glue-gun-like device that can be used to print biodegradable bone grafts directly into fractures could revolutionize orthopedic surgery, offering personalized implants that speed healing and cut infection risks.

A newly discovered receptor switch that boosts bone growth could transform how we treat osteoporosis, by stimulating the body’s own bone-building machinery using a targeted drug and even mechanical force.

For the first time, scientists have pieced together the diverse diet of a sauropod species, using advanced technology to assess the fossilized stomach contents that make up the dinosaur's last meal, which took place around 95 million years ago.

Excavations found that the brain of what seems to be a human male contained dark glass formed during the eruption of Mount Vesuvius in 79 CE. The effect can't be explained by lava temperatures alone, but rather a different event from the cataclysm.
