If scientists knew exactly what a breast cancer cell needs to spread, then they could stop the most deadly part of the disease: metastasis.

New research takes a step in that direction.

Scientists are one step closer to finding a defense against dangerous antibiotic-resistant bacteria, sometimes called "superbugs." Researchers have obtained the first visual evidence of a key piece in the puzzle of how deadly superbugs spread antibiotic resistance in hospitals and throughout the general population.

Sticky glue secreted by the bacterium Staphylococcus aureus could be the clue scientists have been searching for to make an effective vaccine against MRSA, medical researchers report.

(Florida State University) A Florida State University researcher who uses high-powered computers to map the workings of proteins has uncovered a mechanism that gives scientists a better understanding of how evolution occurs at the molecular level.

Researchers have uncovered another clue behind the causes of cleft palate and the process that leads to palate formation.

Cataracts, which can have devastating effects on the eye, affect 42 percent of the population between the ages of 70 and 80, and 68 percent of the population over the age of 80, according to the National Eye Institute.

Now, a professor has identified an important step in how cataracts form. This discovery could lead to a better treatment or cure for cataracts in the future.

Using a lowly bloodless worm, researchers have discovered an important clue to how iron carried in human blood is absorbed and transported into the body.

The finding could lead to developing new ways to reduce iron deficiency, the world's number one nutritional disorder.

One of the earliest general anesthetics to be used by the medical profession, chloroform, has shed light on a mystery that's puzzled doctors for more than 150 years -- how such anesthetics actually work.
