Hair dye poisoning is one of the major causes of self-injury. Chemical hair dye, especially paraphenylene-diamine can lead to edemas, rhabdomyolysis, acute metabolic acidosis and renal failure. Scientists from the University of Leeds have extracted natural dyes from blackcurrant waste, generated throughout Ribena blackcurrant production. This natural black dye with zero side effects could be used in fresh new hair dyeing technologies.
A "body-on-a-chip" device that can evaluate the side-effects of drugs on human cells has been developed by researchers at Kyoto University's Institute for Integrated Cell-Material Sciences, according to a study published today in the Royal Society of Chemistry Advances.
