A new discovery by McGill researchers sheds light on how we retain memories over time, even though brain activity is constantly changing. Published in Nature, the preclinical study found the brain's internal compass remains remarkably stable over time. The findings suggest this steady sense of direction may act as an anchor for memory.
A computational method called scSurv, developed by researchers at Institute of Science Tokyo, links individual cells to patient outcomes using widely available bulk RNA sequencing data. The approach uses single-cell reference datasets together with patient survival data to infer the contributions of individual cells within complex tissues. The model identified cell populations associated with survival across several cancers, offering a way to uncover disease-driving cells and support the development of more targeted treatment strategies.
Rising health insurance costs are pushing some Americans to drop their coverage, a new survey finds. About 1 in 10 people who had Affordable Care Act (ACA) plans last year are now uninsured, according to a report from the health policy group KFF.
Adolescents who replaced just half an hour of sedentary behaviors, such as sitting on the couch or spending time at the computer, each day for moderate-to-vigorous physical activity or sleep may lower their insulin resistance, a key factor in preventing the development of Type 2 diabetes, according to preliminary research presented at the American Heart Association's EPI|Lifestyle Scientific Sessions 2026. The meeting is in Boston, March 17–20, 2026, and offers the latest epidemiological science on prevention, lifestyle and cardiometabolic health.
Rheumatoid arthritis is a chronic autoimmune disease that affects millions of people worldwide. This disease prompts the immune system to mistakenly attack body tissues, particularly joints, leading to inflammation, swelling, stiffness and pain.
Biomedical engineers from Brown University have developed a new wound dressing material that releases antibiotic drugs only when harmful bacteria are present in a wound. In the new study, published in the journal Science Advances, the researchers show that the material could help rapidly clear wound infections to accelerate healing while reducing the unnecessary use of antibiotics—a major driver of antibiotic resistance and hard-to-treat "superbug" infections that claim tens of thousands of lives worldwide each year.
Huntington's disease is a devastating brain disorder that slowly robs people of movement, memory, and personality. It is caused by a toxic protein that builds in brain cells and ultimately kills them. For years, scientists have known that this harmful protein doesn't stay put—it spreads from one brain cell to another. However, exactly how that spread happens and how to stop it has remained a mystery.
New research from the Institute of Psychiatry, Psychology & Neuroscience (IoPPN) at King's College London, in partnership with the South London and Maudsley NHS Foundation Trust, has found that the introduction of remote consultations in primary care during the pandemic wasn't associated with an increase of psychiatric hospital admissions for people with anxiety, depression or severe mental illness.
Bacterial meningitis is once again in global headlines, with recent cases linked to the University of Otago in New Zealand and a fast-growing outbreak at the University of Kent in England.
Oral semaglutide (a GLP-1 pill) is not effective at slowing progression in patients with mild Alzheimer's disease, finds the first large Phase III randomized controlled trials on the topic published in The Lancet.
A Finnish clinical imaging study shows that rest tremor in Parkinson's disease is not explained by greater dopamine loss. In contrast, tremor appears to be associated with relatively better-preserved dopamine function. Researchers from the University of Turku and Turku University Hospital, Finland, analyzed clinical data and dopamine transporter (DAT) imaging data from 414 Finnish patients. The cohort consisted of patients examined in routine clinical practice for uncertain parkinsonism or tremor, making the findings exceptionally well generalizable to real-world clinical settings. The results are published in Neurology.
Applying artificial intelligence techniques to cardiac ultrasound data may make it easier to identify patients with advanced heart failure, a new study has found. The study—led by investigators at Weill Cornell Medicine, Cornell Tech, Cornell Ann S. Bowers College of Computing and Information Science, Columbia University Vagelos College of Physicians and Surgeons and NewYork-Presbyterian—offers the prospect of better care for many thousands of patients who may be overlooked due to the difficulty of diagnosing their condition.
Having a primary care physician reduces emergency department (ED) use among patients with end-stage kidney disease receiving dialysis, according to a study published in JAMA Network Open.
No matter the size or severity, wounds on human skin are difficult to monitor while they heal. Biopsies disrupt the wound site and are too invasive for routine, repeated monitoring, and most medical imaging devices that could do the job are large, expensive, and booked up with more pressing diagnostics. Clinicians typically resort to visual inspection or quick measurements of the wound's size over time.
For millions of people living with HIV, a daily regimen of medications is a lifelong necessity. If they stop taking the drugs—commonly referred to as antiretroviral therapy—the virus usually rushes back within weeks. But not for everyone; scientists have been baffled by rare individuals who, after stopping the drug regimen, keep the virus under control for months or even years.
