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.

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.

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.

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.

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.
