Bones

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.

You may think that if a species died out millions of years ago, its design would be too old to have any applications in our technology. A new analysis of pterosaur bones, however, suggests that they could inspire lighter, stronger aircraft materials.

Osteoporosis is typically treated with orally administered drugs, which may take up to a year to have a noticeable effect. A new injectable hydrogel, however, is claimed to drastically boost bone density in as little as two weeks.

Whether they're caused by injury or other factors, missing sections of bone can be quite difficult to replace. A new injectable hydrogel could change that, however, by transforming into a bone regeneration material when exposed to visible light.

The body has a remarkable ability to heal injuries, but it has its limits. Now scientists have developed a way to improve on the natural process, making implants created from a patient’s own blood to regenerate injuries, even repairing bone.
