Motor imagery (MI) is the mental process of imagining certain limb movements, such as raising a hand or walking, without physically performing them. These imagined movements generate distinct patterns of brain activity that can be recorded using electroencephalography (EEG). By decoding these signals, researchers can enable direct communication between the brain and computer, making MI-EEG a powerful tool for applications such as motor rehabilitation and assisted control of wheelchairs and prosthetics. However, the EEG signals generated during MI vary widely between individuals and over time. Traditional MI-EEG methods are often unable to capture and decode complex patterns in EEG signals,…

Critical Path Institute® (C-Path) neurology journal This provides important long-term insight into how symptoms and functional impact change in patients with early Parkinson’s disease (PD). The paper, led by long-time partners of the Critical Path Parkinson’s Disease Consortium at C-Path, Jamie Adams, MD, and Jennifer Mammen, PhD, is titled “Three Years Later: Tracking Troublesome Symptoms and Impact in Patients with Early Parkinson’s Disease.” The study, funded by the Michael J. Fox Parkinson’s Disease Research Foundation (grants #MJFF-024503 and #MJFF-022743), prospectively followed participants for 3 years. Achieving this milestone marks a special moment for our collaborative team. We have championed…

Over the next decade, significant amounts of aluminum from vehicle body panels are expected to enter recycling and recovery systems. Much of this material cannot currently be reused in critical auto parts because it becomes impure due to contamination. This limitation reduced its value. Researchers at the Department of Energy’s (DOE) Oak Ridge National Laboratory (ORNL) are working to change that. A research team has developed a new aluminum alloy called RidgeAlloy that can transform low-value recycled aluminum into a reliable source of material for manufacturing automotive structural parts in the United States. Aluminum is on the DOE’s Critical Materials…

Small organs grown in the lab can be organized into complex shapes. But it’s difficult to use these so-called “organoids” to study diseases because you’ll never do the same thing twice in the same way. Now, scientists at the University of California, San Francisco have created a new material that helps organoids grow in a more predictable way. They mixed microparticles of alginate, a complex carbohydrate derived from algae, into Matrigel, a standard gel used to grow organoids. This made the gel more similar to the soft but supportive environment inside the body, where tissues normally grow. The team was…

Wegovy, a GLP-1 agonist for weight loss, may have the highest risk of “ocular stroke” (ischemic optic neuropathy) and sudden loss of vision of the semaglutide drug. British Ophthalmological Journal. Analysis shows that the risk for Wegovy is almost five times higher than for Ozempic and three times higher for men than for women. Ischemic optic neuropathy (ION for short) is caused by insufficient or blocked blood flow to the optic nerve, causing sudden vision loss in one or both eyes. Although rare, IONs have recently been associated with GLP-1 receptor agonists, particularly semaglutide, sold as Wegovy, Ozempic, and Rybelsus,…

A type of intestinal bacteria called rosemary tilt Specifically associated with improving muscle strength in humans and muscle performance in mice, research published online in the journal intestines. R slope Research shows that it alters certain metabolic processes in the muscles, converting muscle fibers into “fast-twitch (Type II)” fibers designed for short, intense movements such as sprinting or weight training. R slope Dutch and Spanish researchers suggest that probiotics may have potential as a dietary supplement in the treatment of age-related muscle wasting diseases. Researchers explain that loss of muscle mass and strength is a major cause of frailty, reduced…

As artificial intelligence (AI) becomes more commonplace in the medical field, from record keeping to assisting with medication decisions, researchers at the Icahn School of Medicine at Mount Sinai are asking important questions. “How well can AI withstand intense workloads at healthcare system scale?” The new study was published online March 9. npj health system (https://doi.org/10.1038/s44401-026-00077-0) suggests that the answer does not depend on the AI ​​itself, but on how the AI ​​is designed. Researchers have found that healthcare AI systems work much better when tasks are distributed across multiple specialized AI “agents” — software systems that can perform complex…

The gut microbiome – the trillions of bacteria and other microorganisms that live in the gastrointestinal tract – drive essential processes that protect the colon from tissue damage, according to a study co-led by researchers at Cedars-Sinai University of Health Sciences. This discovery is cell, This has important implications for understanding how various intestinal diseases develop. “Our research opens the door to therapies that focus on restoring critical molecular signals in vulnerable regions of the colon,” said Ofir Klein, MD, executive director of Cedars-Sinai Guerin Children’s Hospital, associate director of child health, and David Kaplan and Meredith Kaplan Distinguished Chair…

Myocardial ischemia, the leading cause of heart attacks, remains a leading cause of death and disability worldwide. Delays in diagnosis are directly correlated with increased myocardial necrosis, increased complication rates, and increased mortality. Although conventional 12-lead ECG is the clinical gold standard for ischemia detection, its transient nature prevents it from capturing transient and unpredictable ischemic episodes during continuous monitoring in the outpatient setting. Although wearable ECG devices are excellent at detecting arrhythmias such as atrial fibrillation (>95% sensitivity), their usefulness in ischemia detection has long been limited by subtle multiscale temporal changes in the ECG waveform that indicate the…

Daily fish oil supplements may help lower the risk of serious cardiovascular complications in people with kidney failure and undergoing dialysis. The findings come from a large-scale international clinical trial co-led in Australia by Monash Health and Monash University’s Faculty of Clinical Sciences. The study, known as the PISCES trial, included 1,228 participants receiving dialysis treatment at 26 centers in Australia and Canada. The results were presented at American Society of Nephrology Kidney Week 2025. New England Medical Journal. Large clinical trial showed 43% reduction in serious cardiac events Participants who took 4 grams of fish oil daily had significantly…
