A recent study presented at the 2022 ARRS Annual Meeting found that COVID-19 infection significantly impacted lung cancer screening in diverse inner-city populations. The research revealed that approximately 9% of participants developed COVID-19 during the pandemic, with mortality rates reaching 6.9%.
Researchers have shown ablation therapy can correct stomach dysrhythmias, eliminating abnormal electrical activity and restoring normal function. The technique may now be able to treat patients suffering from gastrointestinal disorders.
Researchers found that Australian native rushes, including Phragmites australis, can significantly remove PFAS chemicals from contaminated surface water. The study used floating wetlands as a mechanism for plants to grow hydroponically and showed a 42-53% removal of legacy PFAS contaminants.
Dr. Gary J. Whitman, MD of the University of Texas MD Anderson Cancer Center, has been appointed as the 122nd President of the American Roentgen Ray Society (ARRS). He succeeds Jonathan Kruskal, MD, PhD, and will serve for the next year.
Researchers discovered a novel connection between superposition and entanglement that goes beyond quantum theory, applicable to more exotic theories. This equivalence has practical implications for ultra-secure encryption, including popular protocols like BB84.
Scientists have created cilia-free human pluripotent stem cells that exhibit symptoms of ciliopathy, such as polycystic kidney disease. These cells can be used to study the cause of these diseases and guide therapy development.
A large-scale international study, led by Tel Aviv University's Dr. Omri Bronstein, found that many species of echinoids, including sea urchins, survived a mass extinction event 50 million years earlier than thought. The findings suggest that estimates of evolutionary timelines may err by tens of millions of years.
Research at Mount Sinai Hospital found a significant difference in the prevalence of occult hypoxemia among Black, Hispanic, and White patients undergoing anesthesia. The study showed that Black and Hispanic patients experienced higher rates of unrecognized low oxygen levels despite normal pulse oximeter values.
A new methodology has been demonstrated to achieve full 360° active phase modulation for metasurfaces while maintaining uniform levels of optical amplitude. The strategy involves using two optical resonances with specific properties to overcome the trade-offs between dynamic phase and amplitude control.
A CU Boulder study shows that tree fitbits can pinpoint precise timing of tree activities like spring bloom or autumn leaf change. The technology could predict agriculture needs, forecast leaves changing color, detect snow in forest canopies, and track tree damage.
A study led by Kobe University researchers found that idiopathic autism is caused by epigenetic abnormalities in hematopoietic cells, leading to immune dysregulation and brain-gut axis disorders. The study used BTBR mice as a model and identified histone deacetylase HDAC1 as a common mechanism underlying these pathologies.
