Read moreEmbryonic 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...
Life Sciences | Read moreDeciphering the regulatory code
Embryonic development is like a well-organised building project, with the embryo’s DNA serving as the blueprint from which all construction details are derived. Cells carry out different funct...
Life Sciences | Read moreUnraveling the mechanisms behind organ regeneration in zebrafish
Now researchers at the Salk Institute for Biological Studies have identified an essential cellular pathway in zebrafish that paves the way for limb regeneration by unlocking gene expression patterns l...
Life Sciences | Read moreResearchers To Perform Sex Change Operation On Papaya
The NSF grant will fund basic research on the papaya sex chromosomes and will lead to the development of a papaya that produces only hermaphrodite offspring, an advance that will enhance papaya health...
Life Sciences | Read moreThe skeleton: Size matters
Vertebrates have in common a skeleton made of segments, the vertebrae. During development of the embryo, each segment is added in a time dependent manner, from the head-end to the tail-end: the first ...
Life Sciences | Read moreStanford scientists turn stem cells into precursors for sperm, eggs
Researchers at the school have devised a way to efficiently coax the cells to become human germ cells — the precursors of egg and sperm cells — in the laboratory. Unlike previous research, which yield...
Life Sciences | Read moreWhat Drives Our Genes? Researchers Map the First Complete Human Epigenome
Now, researchers at the Salk Institute provide the first detailed map of the human epigenome, the layer of genetic control beyond the regulation inherent in the sequence of the genes themselves....
Life Sciences | Read moreID3 provides career counseling for blood progenitors, driving the creation of gamma-delta T cells
Like an unusually forceful career counselor, the Id3 protein decides the fate of a given white blood cell precursor, according to researchers at Fox Chase Cancer Center. Their findings, published toda...
Life Sciences | Read moreGenetics of Patterning the Cerebral Cortex: How Stem Cells Yield Functional Regions in “Gray Matter”
In the Oct. 11 advance online edition of Nature Neuroscience, scientists at the Salk Institute for Biological Studies report that they have identified the first genetic mechanism that determines the r...
Life Sciences | Read moreLiver cells grown from patients' skin cells
Scientists at The Medical College of Wisconsin in Milwaukee have successfully produced liver cells from patients' skin cells opening the possibility of treating a wide range of diseases that affe...
Life Sciences | Read moreChinese and American paleontologists discover a new Mesozoic mammal
An international team of paleontologists has discovered a new species of mammal that lived 123 million years ago in what is now the Liaoning Province in northeastern China. The newly discovered animal...
Earth Sciences | Read moreResearchers Identify Gene That Regulates Breast Cancer Metastasis
Deaths of most breast-cancer patients are the result of metastasis, a complex, multi-step, and poorly understood process. “Identifying the gene that suppresses the spread of tumor cells and the mechan...
Life Sciences | Read moreNew type of genetic change identified in inherited cancer
Inherited differences in gene copy number, known as copy number variation (CNV), have been implicated in some hereditary diseases but none of the previously discovered familial cancer genes has had CN...
Life Sciences | Read moreUmbilical Cord Blood as a Readily Available Source for Off-the-shelf, Patient-specific Stem Cells
“Cord blood stem cells could serve as a safe, “ready-to-use” source for the generation of iPS cells, since they are easily accessible, immunologically immature and quick to return to an embryonic stem...
