NHGRI aims to make DNA sequencing faster, more cost effective

...d probes, the methods of force spectroscopy can be advanced into techniques having massively parallel format, where millions of single DNA base additions can be followed at the same time. The identification of bases will be done exclusively on the basis of changes experienced by the molecule as a whole. The t...

Pourquié lab identifies genes involved in formation of vertebral precursors

... The paper was published on Science Express, the advanced publication Web site of Science Magazine on Nov. 9, 2006. Dr. Pourquié's lab has long studied the formation of the spine and the role of an internal mechanism -- the clock oscillator -- that regulates the formation somites, the precursors of ver...

Replacing insulin is top-ranked breakthrough foreseen for health in developing world

...ules, genetic engineering, tissue engineering, and advanced cell therapy. There is increasing research in regenerative medicine in both developed and developing countries. Already regenerative medicine has produced a skin substitute (Apligraf), a bone regenerating therapy (Osteocel) and other medical breakth...

Molecular structure reveals how botulinum toxin attaches to nerve cells

...akes to gain entry into human neurons. In an advanced online publication of the journal Nature, the scientists show structurally how botulinum neurotoxin B (one of seven toxins the bacterium produces) recognizes receptors on the surface of human neurons. The structure reveals how these toxins work at th...

Protein folding: Building a strong foundation

...d a solid, sturdy chassis. A new study combining advanced computational modeling and cutting-edge experiments by molecular biologists at Rice University and Baylor College of Medicine suggests that the most stable parts of a protein are also the parts that fold first. The findings appear in the Sept. 13 i...

Innovative movies show real-time immune-cell activity within tumors

Using advanced new microscopy techniques in concert with sophisticated transgenic technologies, scientists at The Wistar Institute have for the first time created three-dimensional, time-lapse movies showing immune cells targeting cancer cells in live tumor tissues...
