As the population ages, arthritis will become more prevalent. It would be helpful to know more about the causes and treatments of cartilage wear.
Michael Furey, Virginia Tech professor emeritus of mechanical and biomedical engineering, recently conducted the first study of wear in human cartilage. Furey will report his research and results at the 231st American Chemical Society National Meeting in Atlanta March 26-30.
Furey has been studying lubrication and wear of cartilage for 20 years. Many years ago, he took a one-year sabbatical to work at the Boston Childrens Hospital Medical Center to carry out studies of cartilage wear using bovine cartilage. He demonstrated the importance of fluid biochemistry on wear. In one example, a complex protein isolated by David Swann reduced cartilage wear by 90 percent when added to a saline reference fluid-a level equaling that of normal bovine synovial fluid.

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...

What if a sensor sensing a thing could be part of the thing itself? Rice University engineers believe they have a two-dimensional solution to do just that.
Rice engineers led by materials scientists Pulickel Ajayan and Jun Lou have developed a method to make atom-flat sensors that seamlessly integrate with devices...
