Scientists propose new hypothesis on the origin of lifeThe scientists suggest that life on Earth originated at photosynthetically-active porous structures, similar to deep-sea hydrothermal vents, made of zinc sulfide (more commonly known as phosphor). They argue that under the high pressure of a carbon-dioxide-dominated atmosphere, zinc sulfide ...

Stem cells, down to one factor -- The NicheDifferentiated human cells have been reprogrammed to an embryonic-like state with the addition of only one gene, rather than the standard four. This should advance techniques for the efficient production of high-quality patient-specific stem cells.
