Brain cell precursors show constant myelin-making drive

In experiments with mice, Johns Hopkins Medicine scientists report new evidence that precursors of myelin-producing cells - one of the few brain cell types that continue to be produced in the adult brain - undergo differentiation widely and at a constant pace, rather than "as needed" in response to injury or advancing age.

Brain complexity declines in Alzheimer's disease

As individuals with Alzheimer's disease (AD) move from the mild cognitive impairment stage to moderate and severe dementia, complex awareness deteriorates although lower-level sensory awareness is relatively maintained.

Pre-surgical medication use grows for pancreatic, gynecologic, and abdominal lining cancers

The second annual report from the National Cancer Database (NCDB) of the American College of Surgeons (ACS) documents a substantial rise in medication treatments, such as chemotherapy, immunotherapy, and hormone therapy, used before surgery to treat many cancers, often allowing less invasive surgery and helping clinicians assess how a patient's cancer responds to medication to guide the most effective treatment options.

Moffitt researchers develop a new way to predict how cancer cells evolve

Researchers at Moffitt Cancer Center have developed a new way to predict how cancer cells evolve by gaining and losing whole chromosomes, changes that help tumors grow, adapt and resist treatment.

FIU's personalized cancer treatment shows promise

Researchers at FIU are advancing a personalized approach to cancer treatment that is showing increasingly promising results for patients with hard-to-treat disease, supported by new philanthropic investment that is helping expand the science behind the work.

Discovery explains why people with IBD have higher risk of colorectal cancer

A chain of immune reactions in the gut—driven by a key signaling protein and a surge of white blood cells from the bone marrow—may help explain why people with inflammatory bowel disease (IBD) have a higher risk of colorectal cancer, according to a preclinical study by Weill Cornell Medicine investigators.

Facial wound secrets revealed for scarless repair

Tweaking a pattern of wound healing established millions of years ago may enable scar-free injury repair after surgery or trauma, Stanford Medicine researchers have found.

Alterations in liver metabolism experienced by individuals with Down syndrome

Researchers at the University of Colorado Anschutz Linda Crnic Institute for Down Syndrome (Crnic Institute) have uncovered compelling evidence that individuals with Down syndrome experience significant alterations in liver metabolism, including elevated levels of bile acids in the bloodstream and other biomarkers of liver dysfunction.

Methionine: A dietary key to surviving infection

As soon as you are wounded-whether from grabbing a hot pan or contracting the flu-you begin a unique journey through variable symptoms toward either recovery or death.

Medicare Advantage skews hospital readmission penalties

For more than a decade, hospitals have worked to help older adults avoid repeated inpatient stays, incentivized by a federal program that cuts Medicare reimbursements if hospitals have higher-than-expected rates of readmissions for people with certain conditions.

Age-related changes in the gut microbiota impair intestinal stem cell function

A new study led by Hartmut Geiger at the University of Ulm, Germany, and Yi Zheng and Kodandaramireddy Nalapareddy, Cincinnati Children's Hospital Medical Center (CCHMC), USA reveals that age-related changes in the gut microbiota directly impair intestinal stem cell (ISC) function and that restoring a youthful microbial environment can reverse this decline.

Researchers decipher a key mechanism that controls pancreatic cancer growth

Could this mark a shift in how we think about cancer therapy? At least in the laboratory, evidence suggests it may be.

Short naps refresh the brain for better learning

Even a short afternoon nap can help the brain recover and improve its ability to learn. In a study published on January 22, 2026, in the journal NeuroImage, researchers at the Medical Center - University of Freiburg, Geneva University Hospitals (HUG) and University of Geneva, show that even a nap is enough to reorganize connections between nerve cells so that new information can be stored more effectively.

Myosteatosis: An emerging predictor of outcomes in chronic liver disease

Myosteatosis, the pathological infiltration of fat into skeletal muscle, is increasingly recognized as a key predictor of poor clinical outcomes across a spectrum of liver diseases.

High BMI linked to vascular dementia risk

High body mass index (BMI) could cause a higher risk of vascular-related dementia (a combination of vascular + unspecified dementia), according to new research from the University of Bristol and University Hospital of Copenhagen (Rigshospitalet and Herlev-Gentofte hospital).

Researchers propose a new framework for understanding neutrophils

Researchers from Universidad Carlos III de Madrid (UC3M), the National Center for Cardiovascular Research (CNIC), and Yale University (USA) have published a comprehensive review article in the journal Cell that proposes a new framework for understanding neutrophils, the most abundant cells of the immune system.

Unfolding the role of Hsp70 chaperones in neurodegeneration

Neurodegenerative diseases such as Alzheimer's, Parkinson's, Huntington's, and amyotrophic lateral sclerosis (ALS) affect millions of people worldwide, yet treatments remain largely limited to symptom management.

Regular aerobic exercise slows a key marker of brain aging in midlife

Regular aerobic activity significantly reduces brain-PAD, indicating that exercise is crucial for maintaining brain health and reducing dementia risk.

Super-enhancers: Cancer's double-edged sword of growth and DNA damage

New study shows that cancer damages its own DNA by pushing key genes to work too hard. Researchers found that the most powerful genetic "on switches" in cancer cells, called super-enhancers, drive unusually intense gene activity.

Lifelong health: The Northern Finland Birth Cohort 1966 enters a new era of aging research

One of the world’s most extensive birth cohorts is now entering later adulthood. At the University of Oulu in Finland, the Northern Finland Birth Cohort 1966 (NFBC1966) is launching a major new follow-up combining decades of biological, social, and environmental data with modern digital health tools to examine how lifelong exposures and the genome shape health and aging.
