(Philadelphia, PA) - About 6.2 million Americans suffer from heart failure, an incurable disease with a staggering mortality rate - some 40 percent of patients die within five years of diagnosis. Heart failure is one form of heart disease, for which new therapies are desperately needed. Now, in new work, scientists at the Lewis Katz School of Medicine (LKSOM) at Temple University identify a path to a promising novel therapeutic strategy, taking aim at a molecule in the heart known as G protein-coupled receptor kinase 5 (GRK5). In a study published online in the journal Cardiovascular Research, the scientists show in mice that reducing GRK5 levels can significantly improve survival ...

Scientists have long theorized that supermassive black holes can wander through space--but catching them in the act has proven difficult. Now, researchers at the Center for Astrophysics | Harvard & Smithsonian have identified the clearest case to date of a supermassive black hole in motion. Their results are published today in the Astrophysical Journal. "We don't expect the majority of supermassive black holes to be moving; they're usually content to just sit around," says Dominic Pesce, an astronomer at the Center for Astrophysics who led the study. "They're just so heavy that it's tough to get them going. Consider how much more ...

Since the pandemic hit, researchers have been uncovering ways COVID-19 impacts other parts of the body, besides the lungs. Now, for the first time, a visual correlation has been found between the severity of the disease in the lungs using CT scans and the severity of effects on patient's brains, using MRI scans. This research is published in the American Journal of Neuroradiology. It will be presented at the 59th annual meeting of the American Society of Neuroradiology (ASNR) and has also been selected as a semifinalist for that organization's Cornelius Dyke Award. The results show that by looking at lung CT scans of patients diagnosed with COVID-19, physicians may be able to predict just how badly they'll experience other ...

ITHACA, N.Y. - A new Penn State and Cornell study describes an effort to produce the most comprehensive and high-resolution map yet of chromosome architecture and gene regulation in yeast, a major step toward improving understanding of development, evolution and environmental responses in higher organisms. Specifically, the study mapped precise binding sites of more than 400 different chromosomal proteins in the yeast genome, most of which regulate the expression of genes. Yeast cells provide a simple model system with 6,000 genes, most of which are found in other organisms, including humans, making them excellent candidates for studying fundamental genetics and complex biological pathways. The paper, "A High-Resolution Protein Architecture of the Budding Yeast ...

Around three times as many males are diagnosed with autism than females. This suggests that biological sex factors may play a role in the development and presentation of autism. Studies on the neurobiology (brain biology) of males and females with autism have begun to examine brain networks but results have been mixed. This is largely due to the limited availability of data from autistic females. In response, researchers from END ...

Humans rely on nature extensively for everything from food production to coastal protection, but those contributions might be more threatened than previously thought, according to new findings from the University of Colorado Boulder. This research, out today in Nature Communications, looked at three different coastal food webs that include those services provided to humans, or ecosystem services, and found that even if the services themselves aren't directly threatened, they can become threatened when other species around them go extinct--often called secondary ...

More than one million operations are performed in Switzerland every year. A surgeon's skill has a direct impact on the outcome of the operation. Training and experience, as well as momentary fatigue and other influencing factors all play a role. At present, skill is tested by experts, either directly during an operation or by evaluating video footage. This approach is very costly and only a limited number of experts are available. Moreover, the assessment may vary and is not always fully reproducible. For some time, attempts have been made to automate and objectify the assessment of surgeons' skills. Proof of feasibility The key result of the study is the proof of the fundamental feasibility of an ...

Colloidal suspensions of microscopic particles show complex and interesting collective behaviors. In particular, the collective dynamics of colloids is fundamental and ubiquitous for materials assembly, robotic motion, microfluidic control, and in several biological scenarios. The collective dynamics of confined colloids can be completely different from that of free colloids: for instance, confined colloids can self-organize into vortex structures, coherent motion, or different phase behaviors. On one hand, due to the complexity of colloidal suspensions, how to finely tune the ...
