With evolution there’s always a trade-off – long necks may help you find food but they’re also a massive weak spot. Now, paleontologists have found direct fossil evidence of prehistoric, long-necked marine reptiles being decapitated by predators.
-
We may soon be giving our unwanted eggshells to science, thanks to new research that has used the humble chicken eggshell to create a new bioactive material for making safe, effective bone grafts.

Calcium carbonate is an impressive material, in that it combines strength, light weight and porosity. Scientists have devised a new bacteria-based method of 3D-printing the substance, for uses such as bone repair and coral reef restoration.

A common diabetes drug has been linked to a reduction in the need for joint replacement surgery. The observational study suggests the drug could be helpful for patients with osteoarthritis, although further clinical work is needed to validate the association.
-
While bone injuries such as fractures typically heal on their own, large sections of missing bone often never grow back, requiring bone transplants from other parts of the body. A new hydrogel, however, could help change that.
-
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.
