Engineers tap machine to simulate spine

To improve the human machine, look to another machine.

Purdue University engineers are working with hydraulic machines and software to help industry create better implants for people suffering from spinal injuries and diseases.

The School of Biomedical Engineering uses spines from cadavers to test implants for the lower back and neck, which present challenges not found in other body parts.

Tests are done in the "spine simulator."

This one-of-a-kind machine mimics the spine's natural movements to show how the implants stand up to everyday activities.

Treatment for warts

Got warts? Get a shot.

If burning and freezing treatments haven't worked, an injection of an antigen that stimulates the body's own defenses might.

The most common shot used is called Candida antigen, derived from the common yeast that causes infections in women.
