Nanotechnology: The art of molecular carpet-weaving Posted: 29 Dec 2011 08:22 AM PST Stable two-dimensional networks of organic molecules are important components in various nanotechnology processes. However, producing these networks, which are only one atom thick, in high quality and with the greatest possible stability currently still poses a great challenge. Scientists have now successfully created just such networks made of boron acid molecules.

Are superluminal neutrinos possible? Pions don't want to decay into faster-than-light neutrinos, study finds Posted: 23 Dec 2011 08:41 AM PST Physicists have put their finger on a problem with the now-famous OPERA experiment that reported faster-than-light, or superluminal neutrinos. They raise theoretical considerations that would make the creation of superluminal neutrinos impossible.

Extracellular matrix could lead to advances inregenerative medicine Posted: 20 Dec 2011 07:25 AM PST Scientists have created a functional model of the native extracellular matrix that provides structural support to cells to aid growth and proliferation. The model could lead to advances in regenerative medicine. The extracellular matrix provides the physical and chemical conditions that enable the development of all biological tissues. It is a complex nano-to-microscale structure made up of protein fibers and serves as a dynamic substrate that supports tissue repair and regeneration.

Nanotechnology may speed up drug testing Posted: 19 Dec 2011 12:27 PM PST Testing the effectiveness of new pharmaceuticals may get faster thanks to a new technique incorporating quantum dots.

Nanotechnology: Nanomechanical measurements of unprecedented resolution made on protein molecules Posted: 19 Dec 2011 07:22 AM PST Physicists have made nano-mechanical measurements of unprecedented resolution on protein molecules.

New system may one day steer microrobots through blood vessels for disease treatment Posted: 16 Dec 2011 08:28 AM PST Researchers use a magnetic field to generate both side-to-side and corkscrew-like motions of tiny robots.

New device creates lipid spheres that mimic cell membranes Posted: 16 Dec 2011 08:28 AM PST A new way of manipulating fluids on microscopic levels brings us one step closer to "bottom-up" artificial cell constructs.

New bandage spurs, guides blood vessel growth Posted: 15 Dec 2011 10:58 AM PST Researchers have developed a bandage that stimulates and directs blood vessel growth on the surface of a wound. The bandage, called a "microvascular stamp," contains living cells that deliver growth factors to damaged tissues in a defined pattern. After a week, the pattern of the stamp "is written in blood vessels," the researchers report.
