NEW YORK, NY (Oct. 7, 2021)–After infection with SARS-CoV-2, where does the immune system store the memory to provide long-term protection against reinfection? Though numerous studies have examined blood to track immune responses to SARS-CoV-2, a new study of COVID survivors shows that the memory of the infection is primarily stored in T and B cells within the lung and the lymph nodes...

Non-invasive brain stimulation of the elderly may improve mobility
Tel Aviv University (TAU) researchers have found that non-invasive, gentle brain stimulation in older adults can improve their ability to walk or stand while simultaneously carrying out a cognitive task, a common dual-task situation that can determine their overall functionality. The study was led by Professor Jeffrey Hausdorff of TAU’s Sackler Faculty of Medicine, the Sagol School of Neuroscience, and...

Detailed analysis of the brain region that controls our movements
Researchers at Karolinska Institutet have participated in a large international research project that has identified all cell types in the motor cortex, the part of the brain that controls movement. The research has resulted in a detailed cell atlas presented in a large special package of scientific articles in Nature. The long-term goal of the...

Tiny bubbles can be future treatment for inflammation
Scientists hope that tiny sacs of material excreted by cells – so-called extracellular vesicles – can be used to deliver drugs inside the body. Researchers at Karolinska Institutet now show that these nano-bubbles can transport protein drugs that reduce inflammation caused by different diseases. The technique, which is presented in Nature Biomedical Engineering, shows promising...

New insights into actions of insulin and their potential impact in treating diabetes
TATA INSTITUTE OF FUNDAMENTAL RESEARCH Insulin is one of the most well known hormones in the human body for its role in regulating blood glucose. While its absence or inaction causes diabetes (Type-I and Type-II), it is also associated with several metabolic disorders such as obesity, hypertension, cancer, and aging. Levels of insulin, produced by...

Of two common weight loss surgeries, one is safer but may be less effective
When comparing two of the most common weight loss surgeries, a research team led by University of Michigan Health found that long-term, sleeve gastrectomy is safer than gastric bypass for Medicare patients. Five years after each procedure, patients who’d undergone a sleeve gastrectomy, which involves removing part of the stomach, had a lower risk of...
