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.

A molecule that helps regulate gene activity has also been shown to drive skin cancer growth and tumors’ ability to evade attack by the body’s immune system, a new study shows.
