What started as an investigation into developmental mouse biology has become a lot more than that. Biologist Katsuhiko Hayashi discovered a way to turn mouse skin cells into sperm and egg cells — and actually used these modified cells to create a living baby mouse. The question is, can it work in humans?
Three cheers for science! Woo, scientists and stem cells! Two-year-old Hannah Warren was born in South Korea without a windpipe. Facing immense health issues, she wasn't expected to live much longer because of her condition. But thanks to the miracle of science and group of badass surgeons and pediatricians, Hannah…
Scientists in Japan have produced a litter of healthy baby mice from eggs created entirely in a laboratory. The same team reportedly fabricated mouse sperm a year ago, but they say that that was no big. It's the fragile, fickle lady eggs that are the real challenge. And now they've done it! From scratch! Woooooooo!
Europe's highest court ruled today that it's not legal for companies to patent any sort of research method that requires the destruction of human embryos. Christian groups are super psyched about this because God says cellbabies are exactly the same as grown up humans with faces and feelings. Scientists are upset…
In a step forward in stem cell research, scientists have created the cells by combining a human egg with skin-cell DNA. However, this doesn't eliminate the need for more controversial embryonic stem cell research.
Japanese scientists say they've taken a "hugely exciting" step forward in the treatment of male infertility. After implanting sperm cells made from embryonic stem cells into infertile mice, the animals were able to father healthy offspring. The researchers hope to someday create sperm from the skin cells of infertile…
Would you trade hip, butt or belly fat for somewhat larger breasts—if safe and "natural" feeling? The discovery of stem cells in fat tissue could make this more than hypothetical, and implications go beyond the beauty myth.
Scientists have found evidence that adult women have stem cells in their ovaries that let them generate more eggs, challenging the long-standing belief that women are born with a fixed number of ova.
