A new study by Silent Spring Institute identified dozens of hazardous chemicals in hair extensions, including products made from human hair, providing the strongest evidence yet of the potential health risks associated with this largely unregulated category of beauty products that disproportionately affect Black women.

Genetically modified immune cells can offer precious additional time to patients with advanced multiple myeloma. However, these therapies lose their impact as the molecules on cancer cells that immune cells recognize gradually vanish. Researchers at the Technical University of Munich (TUM) have now identified one of the molecular mechanisms behind this process. In an initial study they succeeded in blocking it using an existing cancer drug.

New research, led by experts at the University of Nottingham, has found that smoking prevalence among 12 to 30-year-olds in England could drop below 5% decades earlier than expected, if the government progressively raises the age of tobacco sale.

Researchers have developed a novel animal model that fundamentally changes the understanding of lupus, a complex autoimmune disease. They demonstrate for the first time that a defect in skin cells can initiate a cascade of immune events leading to systemic illness. The model, which is both controllable and reversible, faithfully replicates the full spectrum of lupus, from isolated skin lesions to multi-organ systemic disease, providing an unprecedented tool for research and drug discovery.

South Asian adults begin developing risk factors for heart disease earlier—by their mid-40s—according to an analysis of data from two long-running health studies in the United States.
