Rice University tissue engineers set sights on meniscus

Researchers at Rice University are working on growing replacement cartilage for the meniscus, a kidney-shaped wedge of cartilage that cushions stress in the knee joint. By developing methods to simulate mechanical conditions and grow tissue in precise shapes, they aim to create more effective treatments for osteoarthritis.

On the nose

A new USC study suggests that humans lost the ability to detect pheromones due to a gene essential for vomeronasal organ function. The study found that mutations in this gene occurred around 40 million years ago, leading to the disappearance of the gene and subsequent loss of vomeronasal organ function in primates.
