Embryonic development—lost in space?
Despite other challenges, biological difficulties may be the primary obstacle to successful mammalian reproduction and development in orbit, according to new findings by Teruhiko Wakayama and his coll...

The zebrafish model has powerful advantages for studying embryonic development, said senior author Michael Tsang, Ph.D., assistant professor, Department of Microbiology and Molecular Genetics, Univers...
Life Sciences | Read moreSalamanders, regenerative wonders, heal like mammals, people
But it turns out that remarkable ability isn't so mysterious after all -- suggesting that researchers could learn how to replicate it in people.Scientists had long credited the diminutive...
Life Sciences | Read moreEmbryology Study Offers Clues to Birth Defects
The study showed that retinoic acid controls the development (or budding) of forelimbs, but not hindlimbs, and that retinoic acid is not responsible for patterning (or differentiation of the parts) of...

RELEVANCE Prior research has indicated that white blood cells produce hydrogen peroxide to kill bacteria, but never before has it been know to act as a kind of “first responder” that alerts healin...

Two groups of researchers from Children’s Hospital Boston, Brigham and Women’s Hospital, and the Harvard Stem Cell Institute (HSCI) -– presenting multiple lines of evidence from zebrafish, mice and mo...
Life Sciences | Read moreMutated gene in zebrafish sheds light on blindness in humans
Among zebrafish, the eyes have it. Inside them is a mosaic of light-sensitive cells whose structure and functions are nearly identical to those of humans. There, biologists at The Florida State Univer...
Life Sciences | Read moreFishing for microdeletions that predispose an embryo to develop cancer syndromes in later life
Current preimplantation genetic diagnosis techniques can detect mutations in very small bits of genes or DNA, but, until now, it wasn't easy to detect deletions involving whole genes or long sect...
