Bones

Repeated knocks to the head are known to carry increased risks to our neurological health, but a new study has sought to fill in important details around what they might mean for the skull, finding they lead to robust increases in bone thickness.

The dinosaur king may yet retain its crown. Earlier this year a study proposed that the iconic Tyrannosaurus rex should be split into three distinct species, but a new analysis says there isn’t enough evidence for such a drastic shake-up.

It’s hard to find a cooler collectible than the skeleton of a long-dead predator. The latest to hit the auction block is a Gorgosaurus, a distant relative of T-rex, which will be offered for sale by Sotheby’s New York in its Natural History sale.

Paleontologists have described a new species of giant carnivorous dinosaur from a fairly complete skeleton in Patagonia. The discovery could help shed new light on the mystery of why such powerful predators had almost comically tiny arms.

Researchers can now assess a person’s risk of developing late-life dementia using data from a common type of bone density scan. The study revealed calcification within the abdominal aorta can double one’s risk of developing dementia over the age of 80.

Paleontologists have discovered the largest raptor dinosaur ever found. The new species, known as Maip macrothorax, was a super predator of the megaraptor family that stalked the forests of Argentina some 70 million years ago.

Osteoporosis is characterized by the deterioration of bone tissue, resulting in weak bones that are easily broken. There may be new hope for treating the disease, however, utilizing a naturally occurring hormone.

After being declared the first known swimming dinosaur in 2020, Spinosaurus was subsequently suspected of being a shore-wader. A new analysis of its bones, however, has swung the needle back towards the concept of it going underwater to hunt its prey.

The most discerning of dinosaur-obsessed kids always knew that Triceratops was the coolest. And now, the coolest specimen of this coolest dinosaur has just gone on public display for the first time – Horridus, the world's most complete Triceratops.

Tyrannosaurus rex is one of the few dinosaurs that has its full scientific name in wide use. But now a new analysis of known fossils reveals that T-rex might be three separate species, including the newly proposed T-imperator and the T-regina.

Regrowing or replacing bone lost to disease is tricky and often painful. In a new study Australian researchers have found a relatively simple way to induce stem cells to turn into bone cells quickly and efficiently, using high-frequency sound waves.

Complex bone fractures can be hard to treat, sometimes requiring the injured bone to be replaced with bone harvested from elsewhere in the body. Thanks to a new material, though, bone-building micro-robots may someday provide an alternative.
