For the first time, researchers have used cells from one species to restore the sense of smell in another. In an article published April 25 in Cell, researchers from Columbia University described how ...

To create mouse-rat "chimeras," researchers injected rat stem cells into mouse embryos that lacked some genes for brain development. Creative Touch Imaging Ltd. / NurPhoto via Getty Images Scientists ...

New research from scientists at the Massachusetts Institute of Technology (MIT) describes a process for converting skin cells directly into neurons that bypasses the induced pluripotent stem cell ...

Possessing two X chromosomes can significantly reduce DNA methylation in mouse embryonic stem cells, potentially explaining why such cell lines have proven unstable in culture, scientists report ...

In recent experiments, rat brain cells filled in for lost neurons in mouse brains, raising new possibilities for growing donor tissues across species. When you purchase through links on our site, we ...

Nerve fibers in the brain and spinal cord are wrapped in an insulating sheath known as myelin. For a long time, this barrier, which is essentially the brain's white matter, was believed to serve the ...

Messenger RNA can travel between different types of stem cells through tunnel-like structures, as revealed by a new study. By studying interactions between mouse and human stem cells, they discovered ...

The mouse on the left is a chimeric with dark eyes and patches of black fur, a result of stem cells derived from a choanoflagellate Sox gene. The wildtype mouse on the right has red eyes and all white ...

Our body controls the levels of sugar in our blood with a hormone called insulin, which is made by beta cells in the pancreas ...

What makes someone a "morning lark" or a "night owl?" Why does jet lag hit us so hard, and why do some people struggle each ...
