The industry around do-it-yourself DNA kits has exploded, with tens of millions of people sending in samples to learn about their family history. But what consumers might consider a lighthearted glimpse into their backgrounds gave Penn sociologist Wendy Roth pause for thought.

Both genetics and early life stress are important factors for mental health problems in adults adopted as children, according to a new study.

According to a new study, cancer cells gain and lose so-called “chromosome arms”, which can change their response to drugs.

Researchers at the RIKEN Center for Integrative Medical Sciences (IMS) in Japan and colleagues at Osaka University have found genetic variations in humans related to specific dietary habits.

Protective cells in the lungs of ex-smokers could explain why quitting smoking reduces the risk of developing lung cancer, Cancer Research UK-funded researchers have determined.

For the first time scientists have released a genetically engineered, self-limiting agricultural pest into an open field. They have evaluated its potential for future crop protection, with promising results.

Most cancers are caused by a large variety of factors that vary from one person to another. To unravel this complexity, genes that contribute to the development of a respective cancer must be identified. Such genes are called oncogenes.

Researchers have uncovered a method to circumvent the complex genome of the axolotl, and consequently identify at least two genes involved in its regeneration.

A new study suggests that not only do individual mammalian cells in a population fail to respond synchronously to estrogen stimulation, neither do individual alleles.

Individuals within a species may all look alike to the average insect, but one paper wasp species has evolved specialized cognitive abilities to recognize individual faces among their peers. How did complex cognition evolve in just this species?
