Royal jelly, the compound bees use to turn common larvae into queens, also stops stem cells from differentiating -- maturing into things like muscle or skin cells. The find has implications for medical treatments involving regenerating human cells.

After eight years spent analyzing the human genome and its many regulatory molecules, a team from Northwestern University has discovered a seemingly foolproof self-destruct pathway that can be used to destroy any type of cancer cell. The mechanism involves the creation of small RNA molecules (siRNAs) that interfere with multiple genes essential to the proliferation of fast-growing, malignant cells, but have little effect on normal, healthy cells.

This is a rare condition characterized by a cleft in the uvula, which is usually median. The clinical forms range from a simple posterior notch to the complete

Knee replacement is a surgery used for people with severe knee damage. Surgeons recommend this type of surgical procedure if the patient's medication and treatment are not helping at all.

In a partial knee replacement, the surgeon only replaces one part of the knee joint.

In 2010, Sherrie Walter lost her ear to cancer. Doctors at John Hopkins Hospital in Baltimore offered her a chance at a new permanent ear built from her own tissue as opposed to a prosthetic ear. Cartilage was removed from her rib cage to form the ear and it was then placed under the skin of her forearm to grow.

Tummy tuck surgery, also known as abdominoplasty, removes excess fat and skin and, in most cases, restores weakened or separated muscles creating an abdominal profile that is smoother and firmer.
