Stem cell microenvironment reverses malignant melanoma

Northwestern University researchers have demonstrated how the microenvironments of two human embryonic stem cell (hESC) lines (federally approved) induced metastatic melanoma cells to revert to a normal, skin cell-like type with the ability to form colonies similar to hESCs.

Study of how bacteria change their metabolic networks

Bacteria feel pressures to evolve antibiotic resistance and other new abilities in response to a changing environment, and they react by 'stealing' genetic information from other better-adapted types of bacteria, according to research published in Nature Genetics.

Study reveals how T cells analyze and react to the signals of infection at the immunological synapse

The immune system is highly complex. The cast of characters alone required to marshal an immune response to a foreign invader can number in the millions as the body's soldiers, T cells, are called into action.

New genes that regulate longevity

In an effort to understand the molecular mechanisms that control aging, Howard Hughes Medical Institute researchers and their colleagues have now uncovered 10 new genes that regulate longevity in yeast. The studies also suggest a new model for how aging is slowed when caloric intake is restricted.

Stem cells to repair heart tissue soon after a heart attack

Stem cells derived from human heart tissue develop into multicellular, spherical structures called cardiospheres that express the normal properties of primitive heart tissue, smooth muscle and blood vessel cells, according to a study by Johns Hopkins researchers.

Aspirin advice ignored by those who need it

A daily dose of aspirin is an inexpensive, proven strategy for reducing the likelihood of heart disease among those most at risk for such disorders, yet a new study from the Stanford University School of Medicine shows that aspirin therapy is being used by fewer than one-third of the U.S. outpatients who would benefit from it.
