Ordinary cells have the ability to replace lost organs in plants—a function previously thought to be limited to stem cells—researchers at New York University’s Center for Genomics and Systems Biology and Utrecht University in the Netherlands have found. The findings, which suggest that some roles of stem cells in organ regeneration may be shared by other types of cells, are published in the latest issue of the journal Nature.

There’s an emerging star in the super-food world.
Plums are rolling down the food fashion runway sporting newly discovered high levels of healthy nutrients, say scientists at Texas AgriLife Research.
Plainly, “blueberries have some stiff competition,” said Dr. Luis Cisneros, AgriLife Research food scientist.”Stone fruits are super fruits, with plums as emerging stars.” Continue reading “Plums poised to give blueberries run for the money”
During its career, the potentially fatal hepatitis C virus has banked its success on a rather unusual strategy: its limitations. Its inability to infect animals other than humans and chimpanzees has severely hampered scientists in developing a useful small animal model for the disease. But now, in a breakthrough to be published in the January 29 advance online issue of Nature, Rockefeller University scientists have identified a protein that allows the virus to enter mouse cells, a finding that represents the clearest path yet for developing a much-needed vaccine as well as tailored treatments for the 170 million people across the globe living with the tenacious, insidious and rapidly changing virus.

Researchers at the University of California, Davis have discovered that a prototype drug reduces heart enlargement, one of the most common causes of heart failure.
Heart failure, which occurs when the heart can’t pump enough blood throughout the body, affects 5 million people in the United States. The condition contributes to 300,000 deaths each year. Continue reading “research shows that newly discovered drug reduces heart enlargement”
Engineers at the University of California at San Diego have come up with a way to help accelerate bone growth through the use of nanotubes and stem cells. This new finding could lead to quicker and better recovery, for example, for patients who undergo orthopedic surgery. Continue reading “Bioengineers develop novel method for accelerated bone growth”

For the first time, UCLA researchers have reprogrammed human induced pluripotent stem (iPS) cells into the cells that eventually become eggs and sperm, possibly opening the door for new treatments for infertility using patient-specific cells.
The iPS cells were coaxed into forming germ line precursor cells which include genetic material that may be passed on to a child. Continue reading “Human induced plurtipotent stem cells reprogrammed into germ cell precursors”
