X-rays transformed medicine a century ago by providing a noninvasive way to detect internal structures in the body. Still, they have limitations: X-rays cannot image the body’s soft tissues, except with the use of contrast-enhancing agents that must be swallowed or injected, and their resolution is limited. But a newly developed approach could dramatically change that.

Scientists from NIST and Sandia National Laboratories have added something new to a family of engineered, high-technology materials called metal-organic frameworks (MOFs): the ability to conduct electricity. This breakthrough—conductive MOFs—has the potential to make these already remarkable materials even more useful, particularly for detecting gases and toxic substances.
The ChemCam laser instrument aboard NASA’s Curiosity rover fired its 100,000th shot recently, chronicling its adventures on Mars with a coffee-table-book’s worth of spectral data that might rival snapshots gathered during a long and satisfying family vacation here on Earth. ChemCam zaps rocks with a high-powered laser to determine their composition and carries a camera that can survey the Martian landscape.
New findings by Univ. of California, Irvine (UC Irvine) and German chemists about how cataracts form could be used to help prevent the world’s leading cause of blindness, which currently affects nearly 20 million people worldwide. The UC Irvine team explored and identified the structures of the normal proteins and a genetic mutation known to cause cataracts in young children.
The Information Age will get a major upgrade with the arrival of quantum processors faster and more powerful than today’s supercomputers. For the benefits of this new Information Age 2.0 to be fully realized, however, quantum computers will need fast and efficient multi-directional light sources. While quantum technologies remain grist for science fiction, a team of researchers has taken an important step towards efficient light generation.
A new method to identify previously hidden details about the structures of proteins may speed the process of novel drug design, according to scientists at Rice Univ. A unique combination of computational techniques and experimental data helped Rice theorists predict intermediate configurations of proteins that, until now, have been hard to detect.
A group of Illinois researchers, led by Centennial Chair Prof. of the Dept. of Chemical and Biomolecular Engineering Huimin Zhao, has demonstrated the use of an innovative DNA engineering technique to discover potentially valuable functions hidden within bacterial genomes. Their work was reported in a Nature Communications article.
Molecular Devices has introduced the SpectraMax MiniMax 300 imaging cytometer. The cytometer enables both cellular visualization and stain-free cell-based analysis on the field-upgradable SpectraMax i3 Multi-Mode Microplate Reader.
Promega Corp. has introduced the QuantiFluor ONE dsDNA system, a sensitive, dsDNA-specific fluorescent dye suitable for use in both research and clinical workflows. The dye system is integrated into the Promega Quantus fluorometer and GloMax detection instruments, but is compatible with many fluorometer capable of measuring the appropriate fluorescence excitation and emission spectra.
DNAnexus has announced a collaboration with Stanford Univ. that has resulted in a new 1000 Genomes Project data set of genetic variation. Launched in January 2008, the 1000 Genomes Project was the first international effort to sequence a large number of individual genomes with the goal of developing a comprehensive and freely accessible resource on human genetic variation.
Scientists are reporting development of a squishy gel that, when compressed at a key location such as a painful knee joint, releases anti-inflammatory medicine. The new material could someday deliver medications when and where osteoarthritis patients need it most.
Researchers from the NIST Center for Nanoscale Science and Technology (CNST) have demonstrated a new low-energy electron beam technique and used it to probe the nanoscale electronic properties of grain boundaries and grain interiors in cadmium telluride (CdTe) solar cells. Their results suggest that controlling material properties near the grain boundaries could provide a path for increasing the efficiency of such solar cells.
Sometimes the cure can be worse than the disease. Pharmaceutical drugs are known for their potential side effects, and an important aspect of personalized medicine is to tailor therapies to individuals to reduce the chances of adverse events. Now researchers from North Carolina State Univ. have updated an extensive toxicology database so that it can be used to track information about therapeutic drugs and their unintentional toxic effects.
An international multidisciplinary team including researchers at the Univ. of Illinois at Urbana/Champaign and the National Institute of Biomedical Imaging and Bioengineering has developed a sophisticated ”electronic skin” that adheres non-invasively to human skin, conforms well to contours, and provides a detailed temperature map of any surface of the body.
From green electricity tariffs to car sharing schemes, many sustainable products and services are being brought to market by start-ups. However, there has been relatively little research into how and why individuals take this step and whether their start-ups become a success. Fourteen European institutes coordinated by the Technical Univ. of Munich will be investigating this trend to see what potential it holds for a sustainable economy.
A new technique developed at the Advanced Light Source could help scientists better understand and improve the materials required for high-performance lithium-ion batteries that power electric vehicles (EVs) and other applications. The technique, which uses soft x-ray spectroscopy, measures something never seen before: the migration of ions and electrons in an integrated, operating battery electrode.
