Researchers at the University of Connecticut have developed CARRD, a novel RNA detection method that operates at room temperature without pre-amplification, achieving attomolar sensitivity for viral diagnostics. The technique detected HIV and hepatitis C virus RNA at concentrations 10,000 times lower than standard CRISPR tests, potentially transforming point-of-care diagnostics in resource-limited settings.

Scientists at the University of Cambridge have created three-dimensional embryo-like structures from human stem cells that spontaneously produce blood cells, offering a new window into early human development and a potential source of cells for transplantation. The structures, called ‘hematoids’, develop beating heart cells and blood stem cells without requiring the complex cocktails of growth […]
