Researchers clear hurdle on path toward gene-therapy treatment for disease

One of the most difficult aspects of working at the nanoscale is actually seeing the object being worked on. Biological structures like viruses, which are smaller than the wavelength of light, are invisible to standard optical microscopes and difficult to capture in their native form with other imaging techniques.

Researchers develop high-resolution technology to visualize individual virus particles

In the war against infectious disease, identifying the culprit is half the battle. Now, research professor Shaopeng Wang and his colleagues from the Biodesign Institute at Arizona State University, describe a new method for visualizing individual virus particles. Their research opens the door to a more detailed understanding of these minute pathogens, and may further the study of a broad range of micro- and nanoscale phenomena.

Study discovers multiple effects of SSRIs on cells

A new discovery about selective serotonin reuptake inhibitors (SSRIs) suggests that these drugs, which are used to treat mental health disorders like depression and anxiety, have multiple effects on our cells. In a research report published in the August 2010 issue of GENETICS, researchers used yeast cells to identify secondary drug targets or pathways affected by SSRIs. Such secondary pathways could help explain why different people taking the same drug may experience different effects, and could also lead to new types of drugs altogether.

Scientists develop new imaging technique to create three-dimensional images of melanoma

Melanoma is one of the less common types of skin cancer but it accounts for the majority of the skin cancer deaths (about 75 percent).The five-year survival rate for early stage melanoma is very high (98 percent), but the rate drops precipitously if the cancer is detected late or there is recurrence.So a great deal rides on the accuracy of the initial surgery, where the goal is to remove as little tissue as possible while obtaining "clean margins" all around the tumor.So far no imaging technique has been up to the task of defining the melanoma's boundaries accurately enough to guide surgery.Instead surgeons tend to cut well beyond the visible margins of the lesion in order to be certain they remove all the malignant tissue.Two scientists at Washington University in St. Louis have developed technologies that together promise to solve this difficult problem.

Researchers to develop a prototype for laser based radiation therapy

Currently, new treatment facilities for radiation therapy with ions are built all over the world. These particles destroy cancer cells and have a better ability to spare the surrounding healthy tissue than other techniques. Today, accelerated hydrogen and carbon ions are mainly used to treat inoperable tumors in organs like the brain and bone marrow, which are sensitive to radiation therapy.

Scientists identify role of PNPASE in regulating RNA import into mitochondria

Researchers at UCLA's Jonsson Comprehensive Cancer Center and the departments of Chemistry and Biochemistry and Pathology and Laboratory Medicine have uncovered a role for an essential cell protein in shuttling RNA into the mitochondria, the energy-producing "power plant" of the cell. The import of nucleus-encoded small RNAs into mitochondria is essential for the replication, transcription and translation of the mitochondrial genome, but the mechanisms that deliver RNA into mitochondria remain poorly understood.

Foam in helmets, armor can cause injury

In a counter-intuitive finding, scientists at New York University (NYU) and Polytechnic Institute of New York University (NYU-Poly) report that the foam used in helmets and other body armor indeed absorbs damage when compressed slowly but can cause as much injury as a hard object when hit at high speeds.

Scientists identify new catalytic process to create pharmaceuticals with less chemical waste

Much like two children in the back seat of a car, it can be challenging to get two catalysts to cooperate for the greater good. Now Northwestern University chemists have gotten two catalysts to work together on the same task -- something easily done by nature but a difficult thing to do in the laboratory.The findings, published by the journal Nature Chemistry, will allow medicinal chemists to invent new reactions and produce valuable bioactive compounds faster with less impact on the environment.

Scientists develop carbon based nanoscale to detect single DNA molecules

Researchers at the University of Pennsylvania have developed a new, carbon-based nanoscale platform to electrically detect single DNA molecules.Using electric fields, the tiny DNA strands are pushed through nanoscale-sized, atomically thin pores in a graphene nanopore platform that ultimately may be important for fast electronic sequencing of the four chemical bases of DNA based on their unique electrical signature.The pores, burned into graphene membranes using electron beam technology, provide Penn physicists with electronic measurements of the translocation of DNA.
