Histones and the mystery of cell proliferation
Before cells divide, they create so much genetic material that it must be wound onto spools before the two new cells can split apart. These spools are actually proteins called histones, and they must...
View ArticleParental care improves embryos' development in freshwater blenny
An article published in the journal Animal Biology indicates that parental care improves embryos' development in the river blenny. The article is signed by experts Dolors Vinyoles, Noëlle Fabre and...
View ArticleScientists identify "naïve-like" human stem cell
Scientists from our university and Berlin have identified a type of human stem cell that appears to be "naïve-like"– able to develop into any type of cell. The discovery of this cell type could...
View ArticleThe ethical, legal and political minefield of stem cell research
Human stem cell research holds promise for combating some of the most recalcitrant of diseases and for regenerating damaged bodies. It is also an ethical, legal and political minefield.
View ArticleFairy wren embryos found able to discern between adult calls
(Phys.org) —A trio of researchers with Flinders University in Australia has found that a species of bird, the superb fairy wren, is able to distinguish between adult calls while still inside its egg....
View ArticleIdentifying the source of stem cells
When most animals begin life, cells immediately begin accepting assignments to become a head, tail or a vital organ. However, mammals, including humans, are special. The cells of mammalian embryos get...
View ArticleTurtle populations benefit from cooler rookery
A UWA scientist says cooler winters at Cape Domett, in the mouth of the Kimberley's Cambridge Gulf, may be good long-term news for flatback turtles (Natator depressus).
View ArticleBioengineering study finds two-cell mouse embryos already talking about their...
Bioengineers at the University of California, San Diego have discovered that mouse embryos are contemplating their cellular fates in the earliest stages after fertilization when the embryo has only two...
View ArticleEU court clears stem cell patenting
A human egg used to produce stem cells but unable to develop into a viable embryo can be patented, the European Court of Justice ruled on Thursday.
View ArticleEfforts to save rare northern white rhino continue
Experts will meet in Kenya next month to discuss ways to save the critically endangered northern white rhinos from extinction.
View ArticleTransparent soft PDMS eggshell created as step towards embryo lab on a chip
Lab-on-a-chip (LOC) systems have registered tremendous progress over the past 20 years. Myriad "chip" schemes have already emerged, ranging from the lung-on-a-chip and heart-on-a-chip to the...
View ArticleHow do vertebrates take on their form?
A simple physical mechanism that can be assimilated to folding, or buckling, means that an unformed mass of cells can change in a single step into an embryo organized as a typical vertebrate. This is...
View ArticleEvolving a bigger brain with human DNA
The size of the human brain expanded dramatically during the course of evolution, imparting us with unique capabilities to use abstract language and do complex math. But how did the human brain get...
View ArticleChinese team performs gene editing on human embryo
(Phys.org)—A team of researchers in China has announced that they have performed gene editing on human embryos. In their paper uploaded to the open access site Protein & Cell (after being rejected...
View ArticleBeyond genes: Are centrioles carriers of biological information?
Centrioles are barrel-shaped structures inside cells, made up of multiple proteins. They are currently the focus of much research, since mutations in the proteins that make them up can cause a broad...
View ArticleUpside down and inside out
Researchers have captured the first 3D video of a living algal embryo turning itself inside out, from a sphere to a mushroom shape and back again. The results could help unravel the mechanical...
View ArticleCells "dance" as they draw together during early embryo development
The same kind of contraction that fires our muscles also controls a key stage of mammalian embryo development, according to a new study published in Nature Cell Biology. The research, conducted at EMBL...
View ArticleNew study exposes negative effects of climate change on Antarctic fish
Scientists at University of California Davis and San Francisco State University have discovered that the combination of elevated levels of carbon dioxide and an increase in ocean water temperature has...
View ArticleFrom pluripotency to totipotency
While it is already possible to obtain in vitro pluripotent cells (ie, cells capable of generating all tissues of an embryo) from any cell type, researchers from Maria-Elena Torres-Padilla's team have...
View ArticleNew embryo image processing technology could assist in IVF implantation
A collaboration between biologists and engineers at Monash University has led to the development of a new non-invasive image processing technique to visualise embryo formation. Researchers were able to...
