To touch the microcosmos
What if you could reach through a microscope to touch and feel the microscopic structures under the lens? In a breakthrough that may usher in a new era in the exploration of the worlds that are a million times smaller than human beings, researchers at Université Pierre et Marie Curie in France have unveiled a new technique that allows microscope users to manipulate samples using a technology known as "haptic optical tweezers."

Researchers win $5.25 million NIH grant to develop new single molecule electronic DNA sequencing platform
A team of researchers led by Columbia Engineering professor Jingyue Ju has won a three-year $5.25 million NIH grant to develop a novel integrated miniaturized system for real-time single molecule electronic DNA sequencing. This will help them develop their approach into a robust miniaturized platform that will allow the entire human genome to be deciphered for about $100, creating an ideal platform for personalized medicine and basic biomedical research.

Developing platforms for more accurate DNA sequence reading
Polymer scientist Murugappan Muthukumar at the University of Massachusetts Amherst has received a four-year, $1.08 million grant from NIH's National Human Genome Research Institute to find new ways to control the process of reading the precise order of nucleotides in DNA chains as they pass through a nanopore. The work should lead to cheaper, faster and more accurate gene sequencing for medical research and health care.

Capturing brain activity with sculpted light
Scientists at the Campus Vienna Biocenter (Austria) have found a way to overcome some of the limitations of light microscopy. Applying the new technique, they can record the activity of a worm's brain with high temporal and spatial resolution, ultimately linking brain anatomy to brain function. The journal Nature Methods publishes the details in its current issue.

Programmable glue made of DNA directs tiny gel bricks to self-assemble
A team of researchers at the Wyss Institute of Biologically Inspired Engineering at Harvard University has found a way to self-assemble complex structures out of bricks smaller than a grain of salt. The new method could help solve one of the major challenges in tissue engineering: Creating injectable components that self-assemble into intricately structured, biocompatible scaffolds at an injury site to help regrow human tissues.

Stanford scientists use DNA to assemble a transistor from graphene
Graphene is a sheet of carbon atoms arrayed in a honeycomb pattern, just a single atom thick. It could be a better semiconductor than silicon -- if we could fashion it into ribbons 20 to 50 atoms wide. Could DNA help?

Pico-world of molecular bioscavengers, mops and sponges being designed
A new world of molecular bioscavengers, sponges and mops is now closer. A computer-design method has enabled scientists to build proteins that can recognize and interact with small molecules. The proteins can also be reprogrammed to detect and unite with related substances, such as different forms of steroids. The method might also become a way to give organisms new tools to perform biological tasks.

Electronics advance moves closer to a world beyond silicon
Researchers have made a significant advance in the function of metal-insulator-metal, or MIM diodes, a technology premised on the assumption that the speed of electrons moving through silicon is simply too slow. For the extraordinary speed envisioned in some future electronics applications, these innovative diodes solve problems that would not be possible with silicon-based materials as a limiting factor.
