Bones

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.

A newly discovered fossil may change what we know about an ancient human relative. Vertebrae from the lower back of an Australopithecus sediba reveal it was surprisingly well adapted to walking upright like a human, while also climbing like an ape.

Researchers have developed an ultra-thin device that permanently bonds to bones and beams data out wirelessly. The breakthrough could allow doctors to monitor the health of a patient’s bones over time, or how well they’re healing after an injury.

A study analyzing records from several hundred thousand people has identified a link between low rates of diabetes and osteoporosis patients treated with a common drug. The researchers propose the drug may prevent the development of insulin resistance.

Scientists looking into the biological mechanisms behind deteriorating bones have made a discovery that could help tackle age-related conditions like osteoporosis, by rejuvenating stem cells that to are central to their healthy maintenance.

For many people with arthritic knees, a surgical procedure known as a high-tibial osteotomy (HTO) often brings relief. Thanks to 3D printing technology, however, it could soon be even more effective – and also safer to perform.
