Twice-daily supplements boosted cognitive power over 18 months. Daily consumption of a certain form of curcumin improved memory and mood in people with mild, age-related memory loss, according to the results of a study conducted by UCLA researchers. The research, published online Jan. 19 in the American Journal of Geriatric Psychiatry, examined the effects of an easily absorbed curcumin supplement on memory performance in people without dementia, as well as curcumin’s potential impact on the microscopic plaques and tangles in the brains of people with Alzheimer’s disease.

Found in turmeric, curcumin has previously been shown to ha...

Rutgers researchers identified a small set of simple protein building blocks (left) that likely existed at the earliest stages of life’s history. Over billions of years, these “Legos of life” were assembled and repurposed by evolution into complex proteins (right) that are at the core of modern metabolism.

Rutgers scientists have found the “Legos of life” – 4 core chemical structures that can be stacked together to build the myriad proteins inside every organism – after smashing and dissecting nearly 10,000 proteins to understand their component parts...

Researchers at EPFL have created artificial molecules that can help the immune system to recognize and attack cancer tumors. Immunotherapies are breakthrough treatments that stimulate the patient’s immune cells to attack the tumor through the recognition of tumor antigens. They can be very effective, but currently can only cure a minority of patients with solid tumors. Researchers and physicians are now looking into ways of increasing the precision and strength of the immune attack on the tumor.

One approach is the “dendritic cell vaccine...

Highlights • Non-classical MHC class I molecules promote homeostatic immunity to the microbiota • Commensal-specific T cells express immunoregulatory and tissue repair signatures • Commensal-specific T cells accelerate wound closure

Insights may inform wound management techniques. Beneficial bacteria on the skin of lab mice work with the animals’ immune systems to defend against disease-causing microbes and accelerate wound healing, according to new research from scientists at the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health. Researchers say untangling similar mechanisms in humans may improve approaches to managing skin wounds and treating other damaged tissues.

Like humans and other mammals, mice are inhabited by the microbiome...
