Lizards pull a wheelie

A team of scientists found that lizards running on two legs is due to their acceleration, which creates a turning force acting on the lizard's torso, lifting it off the ground. The researchers suggest that 'pulling a wheelie' is the most likely explanation for the lizards' bipedalism.

Nanoparticles aid bone growth

A new study has shown that adding nanoparticles to porous materials can lead to denser bone tissue. Researchers found that the nanoparticles increased bone ingrowth by threefold after 12 weeks compared to a biodegradable plastic scaffold alone. The study paves the way for further research into tissue engineering and bone regeneration.
