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.

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

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.
