Research published in Nature (21 July) will outline for the first time the stem cell origin of the structure of the neck and shoulders in vertebrates. The scientists believe that instead of groups of stem cells creating the skeletal and muscle structure separately they actually appear to make them together as a sort of ‘composite’. This could have significant implications for clinical medicine and our understanding of vertebrate evolution.
Scientists at the Wolfson Institute for Biomedical Research of University College London, part-funded by the Biotechnology and Biological Sciences Research Council (BBSRC) and working with international collaborators, used a new genetic technique to tag embryonic stem cells and then trace them to the adult animal. They discovered that instead of homogeneous groups of stem cells making up the bones of the shoulder and neck and another making the muscles, a newly-discovered group of stem cells called mesenchymal stem cells make both the muscles and the point where it joins the skeleton.
The researchers believe their results show that the skeleton and muscles of vertebrates should not be seen as separate but instead are composites, with the boundaries between cell groups blurred around the body. For example, the stem cell group that makes the connective tissues of the swallowing/gulping muscles also makes the skeletal regions of the shoulder girdle. This sheds new light on human diseases such as Klippel-Feil syndrome where both regions are often malformed.

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
