Elevated concentrations of strontium, an element associated with oil and gas wastewaters, have accumulated in the shells of freshwater mussels downstream from fracking wastewater disposal sites, according to researchers from Penn State and Union College.
Scleric Acid has been discovered by capturing and engineering a DNA fragment from soil bacteria Streptomyces sclerotialus, and could help fight bacterial infections -- by researchers at the School of Life Sciences and Department of Chemistry, University of Warwick.
Scientists from Zelinsky Institute of Organic Chemistry of Russian Academy of Sciences in Moscow managed to look inside an organic chemical reaction with electron microscope and recorded the occurred transformation in real time. The team from the laboratory of Prof. Ananikov applied combined nano-scale and molecular-scale approaches to the study of chemical transformation in catalytic cross-coupling reaction. The study is published in Nature Communications.
University of Colorado Boulder engineers have developed a 3D printing technique that allows for localized control of an object's firmness, opening up new biomedical avenues that could one day include artificial arteries and organ tissue.
MIT engineers have devised a new technique to detect either electrical activity or optical signals in the brain, using a minimally invasive technique based on magnetic resonance imaging (MRI).
Researchers have demonstrated a new way to sequence proteins that is much more sensitive than existing technology, identifying individual protein molecules rather than requiring millions of molecules at a time. The advance could have a major impact in biomedical research, making it easier to reveal new biomarkers for the diagnosis of cancer and other diseases, as well as enhance our understanding of how healthy cells function.
A new neural recording technique developed by EPFL bioengineers enables for the first time the comprehensive measurement of neural circuits that control limb movement. Tested on the fruit fly, results from the technique may inspire the development of more sophisticated robotic control approaches.
In new studies conducted at UC San Francisco, a novel oxygen-delivery therapeutic restored the function of oxygen-starved heart tissue in an animal model of global hypoxia. Unlike its experimental predecessors, the new drug does not appear to cause systemic side effects or overcorrect with excessive blood oxygenation, which can itself be toxic. Instead, the new drug delivers its precious oxygen cargo only to the tissues that need it most.
Scientists at the UCLA Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research and the Stein Eye Institute have been awarded a $5.1 million grant from the California Institute for Regenerative Medicine to advance the development of a novel therapy for blinding retinal conditions.
Researchers have for the first time been able to investigate the abundance and methyl modifications of all mitochondrial tRNAs in patients suffering from one of the most common inherited mitochondrial tRNA mutations. The analysis pipeline revealed quantitative changes that had dramatic effects on protein synthesis within mitochondria.
