Working with mice and rats, Johns Hopkins researchers have developed a way to successfully deliver nano-sized, platinum-based chemotherapy drugs to treat a form of bladder cancer called nonmuscle-invasive that is found in the lining of the organ and has not invaded deeper into bladder tissue. The tiny drug-infused particles, they say, potentially offer a less toxic clinical alternative to standard chemotherapy delivered intravenously or through a catheter inserted into the bladder.

The same electrostatic charge that can make hair stand on end and attach balloons to clothing could be an efficient way to drive atomically thin electronic memory devices of the future, according to a new Berkeley Lab study. Scientists have found a way to reversibly change the atomic structure of a 2-D material by injecting it with electrons. The process uses far less energy than current methods for changing the configuration of a material's structure.

Gold has long been valued for its luxurious glitter and hue, and threads of the gleaming metal have graced clothing and tapestries for centuries. Determining how artisans accomplished these adornments in the distant past can help scientists restore, preserve and date artifacts, but solutions to these puzzles have been elusive. Now scientists, reporting in ACS’ journal Analytical Chemistry, have revealed that medieval artisans used a gilding technology that has endured for centuries.

Viruses exist amidst all bacteria, usually in a 10-fold excess and include virophages which live in giant viruses and use their machinery to replicate and spread. In Nature Communications, a team including DOE JGI researchers reports effectively doubling the number of known virophages.
Johns Hopkins researchers report that the level, or “copy number,” of mitochondrial DNA—genetic information stored not in a cell’s nucleus but in the body’s energy-creating mitochondria—is a novel and distinct biomarker that is able to predict the risk of heart attacks and sudden cardiac deaths a decade or more before they happen. In the future, testing blood for this genetic information could not only help physicians more accurately predict a risk for life-threatening cardiac events, but also inform decisions to begin—or avoid—treatment with statins and other drugs.
