Many imaging technologies and their contrast agents – chemicals used during scans to help detect tumors and other problems – involve exposure to radiation or heavy metals, which present potential health risks to patients and limit the ways they can be applied. In an effort to mitigate these drawbacks, new research from University of Pennsylvania engineers shows a way to coat an iron-based contrast agent so that it only interacts with the acidic environment of tumors, making it...

New effort prioritizes transparency, consistency and rigor The American Cancer Society has revised its guideline formation process to achieve greater transparency, consistency, and rigor in creating guidance about cancer screening. The new methods align with new principles from the Institutes of Medicine (IOM) by creating a single generalist group for writing the guidelines, commissioning systematic evidence reviews, and clearly articulating the benefits, limitations, and harms associated...

Carnegie Mellon University's Roberto R. Gil and Rongchao Jin have successfully used NMR to analyze the structure of infinitesimal gold nanoparticles, which could advance the development and use of the tiny particles in drug development. Their approach offers a significant advantage over routine methods for analyzing gold nanoparticles because it can determine whether the nanoparticles exist in a both right-handed and left-handed configuration, a phenomenon called chirality. Determining a...

Surpassing the physical limits of silicon After having revealed the electronic advantages of molybdenite, EPFL researchers have now taken the next definitive step. The Laboratory of Nanoscale Electronics and Structures (LANES) has made a chip, or integrated circuit, confirming that molybdenite can surpass the physical limits of silicon in terms of miniaturization, electricity consumption, and mechanical flexibility. "We have built an initial prototype, putting from two to six serial...

As the market for liquid crystal displays and other electronics continues to drive up the price of indium – the material used to make the indium tin oxide (ITO) transparent electrodes in these devices – scientists have been searching for a less costly and more dynamic alternative, particularly for use in future flexible electronics.   Besides its high price, ITO has several drawbacks. It's brittle, making it impractical for use in flexible displays and solar cells, and...

A new episode in the American Chemical Society's (ACS) award-winning "Global Challenges/Chemistry Solutions" podcast series spins a real-life tale in which spider silk shows promise for overcoming a major barrier to the use of gene therapy in everyday medicine. The new installment from the world's largest scientific society explains in non-technical language that gene therapy involves the use of beneficial genes to prevent or treat disease. It requires safe and efficient carriers or...

BIDMC researcher says improvement in survival rates best 'since introduction of aspirin' An oral anti-clotting drug, when added to standard medical treatment for acute coronary syndrome, lowered the risk of death, heart attack or stroke an average of 16 percent, according to research presented at the American Heart Association's Scientific Sessions. The results were also published online by the New England Journal of Medicine. The drug, rivaroxaban, proved effective in preventing the...
