Novel method for designing geometric structures created from DNA

Among the valuable holdings in London's Wellcome Library is a rough pencil sketch made in 1953 by Francis Crick. The drawing is one of the first to show the double-helix structure of DNA--Nature's blueprint for the design of sea snails, human beings, and every other living form on earth.

Leica Microsystems launches IOLcompass Pro intraocular lens positioning system

Leica Microsystems in partnership with TrueVision Systems Inc. launches the IOLcompass Pro. IOLcompass Pro is a software-based guidance system for pre-operative planning and intra-operative positioning of premium intraocular lenses (IOLs). It supports ophthalmic surgeons to achieve minimal residual astigmatism for their patients by providing stable and accurate guidance throughout the cataract surgical workflow.

Theoretical modelling helps to understand interior structures of cubosomes

Under certain conditions appropriately selected particles can form closed surfaces in liquids with surprisingly complex shapes, cutting through space by a regular network of channels. So far, we have looked at cubosomes - for this is what these spectacular three-dimensional nanostructures are called - only from the outside.

Fish's retina inspired autofocus contact lens could benefit presbyopia patients

Making the most of the low light in the muddy rivers where it swims, the elephant nose fish survives by being able to spot predators amongst the muck with a uniquely shaped retina, the part of the eye that captures light. In a new study, researchers looked to the fish's retinal structure to inform the design of a contact lens that can adjust its focus.

Ohio State researchers working on new way to treat drug-resistant cancer

Researchers at The Ohio State University are working on a new way to treat drug-resistant cancer that the ancient Greeks would approve of--only it's not a Trojan horse, but DNA that hides the invading force.

New approach could open door to more personalized medications for diabetes patients

New research from the University of Copenhagen points to an entirely new approach for designing insulin-based pharmaceuticals. The approach could open the door for more personalized medications with fewer side effects for Type 1 Diabetes patients.

Can Nanostructured Microelectrodes be Used to Analyze Biomarkers? An Interview with Dr Shana Kelley

Electrochemical methods are appealing because simple and inexpensive instrumentation can be used to make highly sensitive measurements. However, it has been quite difficult to realize clinically-relevant levels of sensitivity using electrochemistry in highly complex, real-world samples.

New computed tomography method provides internal view of human tooth

Both in materials science and in biomedical research it is important to be able to view minute nanostructures, for example in carbon-fiber materials and bones. A team from the Technical University of Munich, the University of Lund, Charité hospital in Berlin and the Paul Scherrer Institute have now developed a new computed tomography method based on the scattering, rather than on the absorption, of X-rays.

Northwestern University nanoscientist wins Raymond and Beverly Sackler Prize in Convergence Research

Northwestern University scientist Chad A. Mirkin, one of the world's leaders in nanotechnology research and its application, has been awarded the inaugural $400,000 Raymond and Beverly Sackler Prize in Convergence Research from the National Academy of Sciences.

New approach may bring scientists one-step closer to DNA nanomachines

Scientists have been studying ways to use synthetic DNA as a building block for smaller and faster devices. DNA has the advantage of being inherently "coded". Each DNA strand is formed of one of four "codes" that can link to only one complementary code each, thus binding two DNA strands together.

Scientists explain the existence of intrinsic chirality in ordinary nanocrystals

A team of scientists from ITMO University and Trinity College Dublin published first experimental results showing that ordinary nanocrystals possess intrinsic chirality and can be produced under normal conditions as a half-and-half mixture of mirror images of each other.
