: Carcinogens and mutagens

Cancer is a disease characterized by uncontrolled growth and division of cells. These cells have the ability to invade the organ where they originate, to travel through the blood and lymph fluid to other organs and grow in them. More than 200 different types of diseases (malignant tumours) are included under the term cancer. The latency period of the disease, i.e. the time that elapses between exposure to a carcinogen and clinical detection of resulting cancer can extend for several years.

Mutagens are substances and mixtures which, if inhaled, swallowed or absorbed through the skin, may induce heritable genetic damage or increase its incidence. R45 or H350 May cause cancerR46 or H340 May cause heritable genetic damageR49 or H350i May cause cancer by inhalationR40 or H351 Limited evidence of a carcinogenic effectR68 or H341 Possible risk of irreversible effects June 2017.

Brown Fat, White Fat, Good Fat, Bad Fat

Our two main types of fat—brown and white—play different roles. Now, two teams of NIH-funded researchers have enriched our understanding of adipose tissue. The first team discovered the genetic switch that triggers the development of brown fat [1], and the second figured out how the body can recruit white fat and transform it into brown [2]. Why would we want to change white fat into brown?
