Scientists have discovered how cells ensure the correct distribution of proteins throughout their interior. What they have found is that many of the proteins which need to be transported to the cell membrane are furnished with a kind of anchor consisting of a fatty acid, which serves to embed the proteins in the cell membrane.
Hydrogen would command a key role in future renewable energy technologies, experts agree, if a relatively cheap, efficient and carbon-neutral means of producing it can be developed. An important step towards this elusive goal has been taken by a team of researchers with Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California, Berkeley.
'Children are not small adults' - pediatricians say that's what makes their specialty different from the practice of medicine in adults. For similar reasons, researchers exploring the medical uses of nanotechnology believe that the use of molecular-level nanomedicine techniques in children will also require its own specialty.
Scientists have succeeded for the first time in making, out of DNA double stands, an interlocked molecule (rotaxane) with freely moveable components. This opens up exciting possibilities for nanorobotics and synthetic biology.
The application of nanotechnology will have a major influence in many fields of medicine. Novel nano-based materials appear in drug delivery systems, diagnostics, imaging, biosensing, and medical materials and devices.
Forget what you know about how diseases are diagnosed. New research details a noninvasive ground-breaking tool that detects signs of disease at early molecular stages before symptoms can be seen using traditional methods.
As the pace of changing technology quickens, a robust and open national capability for technology assessment - the process of estimating the broad social, ethical, legal and economic impacts of emerging science and technology - is critical and must include public participation to complement expert analysis, says a new report, 'Reinventing Technology Assessment: A 21st Century Model'.
'Hot sounds' has one meaning to music fans and another to physicists. Count a team of researchers at Rice University among the latter, as they've discovered that acoustic waves traveling along ribbons of graphene might be just the ticket for removing heat from very tiny electronic devices.
