'Billion Dollar Burger' Asks: What Is Meat?
Chase Purdy's briskly paced and quietly bold new book about the future of meat suggests people rethink its meaning, as he explores those at the forefront of developing cell-cultured meat.
Scientists Create A Device That Can Mass-Produce Human Embryoids
Researchers hope large numbers of very primitive, embryo-like structures will lead to new insights into early human development and ways to prevent miscarriages and birth defects.
Scientists Create Immature Human Eggs From Stem Cells
A Japanese research team made immature human eggs from stem cells that were derived from human blood. The technique brings scientists a step closer to being able to mass-produce human eggs.
Will State Voters Continue To Pour Money Into Stem Cell Research?
California alone has spent billions in state funds over the last 14 years to support stem cell research. Scientists want another round of cash. So, what exactly did voters get for their money so far?
FDA Cracks Down On Stem-Cell Clinics Selling Unapproved Treatments
The companies are "unscrupulous actors" marketing stem-cell treatments that have not been proved effective and may be dangerous, the FDA says. It took action against clinics in Florida and California.
A Chip That Reprograms Cells Helps Healing, At Least In Mice
This device shoots new genetic code into cells to make them change their purpose. Researchers say the chip could someday be used to treat injuries in humans. But they've got a long, long way to go.
Brain Cell Transplants Are Being Tested Once Again For Parkinson's
In 2003, researchers declared a moratorium on the use of transplanted brain cells to treat Parkinson's disease. Now, armed with better cells, they're giving the approach another try.
3 Women Blinded By Unproven Stem Cell Treatments
Three patients were blinded after getting stem cells from fat at a Florida clinic. But another patient shows promise after treatment in Japanese study using induced pluripotent stem (iPS) cells.
