New research suggests doctors may be able to improve cure rates by changing treatments before tumors recover. Rather than waiting for the cancer to come back after the first treatment, researchers suggest switching to another treatment while the tumor is still shrinking. This strategy is designed to address one of the biggest obstacles in cancer treatment: drug resistance. Reasons why cancer is likely to recur Dr Robert Noble, a senior lecturer in the School of Mathematics at St George’s, University of London, led the research. “Tumors may initially shrink with treatment, but they often regrow eventually. These recurrences are because…
Researchers at Seoul National University and Seoul National University have developed a programmable photonic integrated circuit that can slow down light whenever needed. The team was led by Professors Namkyoo Park and Seung-gyu Yu from the School of Electrical and Computer Engineering at Seoul National University, and collaborated with Professor Xiangji Piao from the School of Electrical and Computer Engineering at Seoul National University. Slowing down light could help solve computing bottlenecks The rapid growth of generative AI and large-scale AI models has sharply increased the amount of computing power required in data centers and servers. Traditional electronic semiconductors struggle…
A large-scale multi-omics study maps why the epigenetic clock captures different aspects of aging and shows how gene expression scores sharpen the interpretation. Research: How the epigenetic clock ticks: Unpacking the black box by deciphering the biological pathways and transcriptomic signatures of accelerated aging. Image credit: Lightspring / Shutterstock In a recent study published in the journal npj agingA group of researchers identified biological pathways and gene expression signatures associated with the widely used epigenetic clock and assessed how the Transcriptome Aging Gene Score (TAGS) is associated with aging-related health outcomes. background Why do some people remain healthier than others…
A single dose of psilocybin, the psychedelic substance found in magic mushrooms, causes physical changes in the brain that can remain detectable for up to a month, according to researchers at the University of California, San Francisco and Imperial College London. This study nature communicationshealthy adults who had never used psychedelics participated. Although none of the participants had been diagnosed with a mental health condition, the findings may provide clues as to why psilocybin showed promise in treating depression, anxiety, and addiction. The researchers focused on temporary increases in the brain’s “entropy,” a term that describes the diversity and unpredictability…
The American College of Cardiology (ACC) is introducing a new cardiogenic shock designation to improve outcomes for one of the most life-threatening complications of heart attack. This new designation builds on the success of the existing ACC Chest Pain Center designation, which has helped hospitals standardize and improve care for patients presenting with heart attack symptoms, but previously did not address cardiogenic shock. Additionally, new grants supported by Johnson & Johnson will help rural hospitals implement the designation. Cardiogenic shock occurs when the heart suddenly cannot pump enough blood to meet the body’s needs and remains the leading cause of…
A study published online in an open access journal found that certain imbalances and disruptions in the oral microbiome are associated with symptomatic hand arthritis. RMD open. The findings suggest that the oral microbial environment may influence the disease process of hand arthritis, which is associated with pain, stiffness, and decreased grip strength and can significantly impair quality of life. The oral microbiome is involved in systemic inflammation and interacts closely with the gut microbiome, which is highly associated with symptomatic hand arthritis. To assess the role of the oral microbiome, saliva samples from 52 individuals with symptomatic hand arthritis…
Bob covers medical expenses, focusing on health insurance and hospitals. His story delves into Medicare Advantage, opaque prescription drug benefits, and what executives actually earn. He is also the author of the Health Care Inc. newsletter. You can reach Bob at Signal at bobjherman.09.More and more adults are working hard at jobs they don’t like just because they don’t want to lose their health insurance. This phenomenon, known as “job lock,” has existed in the U.S. workforce for decades. Fear of losing health benefits can prevent people from changing jobs or careers, especially those with more health problems or complex…
Researchers working in freshwater streams may or may not deploy traceable bottles that travel to the Neuse River, Pamlico Sound, and ultimately the Atlantic Ocean. Photo: North Carolina Sea Grant Tatiana the Trash was carried by water about 110 miles downstream from where Tatiana the Trash and dozens of other reusable bottles were released into a northeast Raleigh creek more than a year ago. It looks like Dan the Debris won’t be far from where it was placed in Marsh Creek in the spring of 2025. There are now 60 cheekily named bottles that can be traced from the freshwater…
The use of newer GLP-1 receptor agonists (semaglutide or tirzepatide) for obesity or diabetes by people with alcohol use disorder was associated with fewer alcohol-related hospitalizations, a study published online in an open access journal found BMJ Open. The findings suggest a potential role for the drugs semaglutide (Ozempic, Wegovy) and tirzepatide (Mounjaro) in the treatment of alcohol use disorder. GLP-1 receptor agonists are primarily used to treat type 2 diabetes and obesity, but reports of decreased alcohol consumption in patients taking the drugs have prompted the authors to investigate their potential impact on alcohol-related hospitalizations in adults with alcohol…
Researchers outline how low-dose lithium could be tested as a carefully monitored approach to preserving cholinergic function and brain networks before Alzheimer’s disease progresses. Perspective: Revisiting the cognitive abilities of lithium in Alzheimer’s disease: The role of cholinergic systems and brain connections. Image credit: Nanzeeba / Shutterstock With a new perspective that can be used as a “press article” in a journal translational psychiatryresearchers discuss the cognitive benefits of lithium in Alzheimer’s disease (AD). A recent Nature study reported that levels of endogenous lithium in the brains of people with Alzheimer’s disease and mild cognitive impairment (MCI) are significantly reduced.…
