A study carried out by researchers from the Department of Radiology and Physical Medicine of the University of Granada, in collaboration with the Andalusian School of Public Health (Escuela Andaluza de Salud Pública), found that 100% of Spaniards analyzed had at least one kind of persistent organic compound (POC´s), substances internationally classified as potentially harmful to one’s health, in their bodies. These substances enter the body trough food, water or even air. All of them tend to accumulate in human adipose tissue and easily enter into the organism through the aforementioned mediums.

A group of scientists in Princeton's Department of Ecology and Evolutionary Biology has uncovered a new biological mechanism that could provide a clearer window into a cell's inner workings.
