WASHINGTON - Researchers said they had shown cloning can work as a source of grow-your-own transplants, by implanting into cattle cloned cells which formed functioning kidney-like organs and working ...

Two research groups have independently produced human embryonic stem-cell lines from embryos cloned from adult cells. Their success could reinvigorate efforts to use such cells to make ...

WASHINGTON — Scientists at a California company reported yesterday that they had created the first mature cloned human embryos from single skin cells taken from adults, a significant advance toward ...

A complete cloning ban could block many possible clinical applications of stem cell research.” And the only way those “applications” will be discovered is by creating cloned human embryos for research ...

New research indicates that a rhesus monkey (Macaca mulatta), cloned using somatic cell nuclear transfer (SCNT), has successfully survived for over two years. The cloning of rhesus monkeys may ...

With all the work to do, people to see, traffic jams to get stuck in, we all sometimes wish we could be in two places at once ...

The first published report of cloned human stem cells means so-called therapeutic cloning is no longer a theory but a reality, say the Korean and U.S. researchers who announced their results today.

Two groups at Harvard University have announced that they have received approval to start human-cloning research designed to create lines of embryonic stem cells to study and treat diseases. “We are ...

A team of researchers said Wednesday that it had produced embryonic stem cells -- a possible source of disease-fighting spare parts -- from a cloned human embryo. Scientists at the Oregon Health and ...

Scientists in China on Tuesday announced that they have cloned the first healthy rhesus monkey, a two-year-old named Retro, by tweaking the process that created Dolly the sheep. Primates have proved ...

A quality sword requires toughness on the inside and hardness on the outside. That way it can keep a sharp edge yet bend instead of shatter. Getting these properties requires blanking the metal back ...
