A survey in the US found that agreement with the phrase: "It seems like everything causes cancer" is on the increase – even though, thanks to research, we know more about what causes and prevents cancer than ever before.

Alzheimer's gene poses both risk and benefits
Scientists drilling down to the molecular roots of Alzheimer's disease have encountered a good news/bad news scenario. A major player is a gene called TREM2, mutations of which can substantially raise a person's risk of the disease. The bad news is that in the early stages of the disease, high-risk TREM2 variants can hobble the immune system's ability to protect the brain from amyloid beta, a key protein associated with Alzheimer's.

Antisocial behaviour mainly a consequence of gene interactions
Individual genes have little influence in the development of antisocial behaviour. However, the interaction of genes as a whole could explain some of the differences in antisocial behaviour. This was revealed by international research among more than 25,000 participants in which the researchers Jorim Tielbeek, Arne Popma, Tinca Polderman and Danielle Posthuma of VUmc and VU Amsterdam were involved. Tielbeek carried out this research with funding from the NWO programme Research Talent. The research was published today in JAMA Psychiatry.

White supremacy—the dark side of eugenics
Whenever I work on a new edition of my human genetics textbook and reach the section on eugenics, at the end of an evolution chapter, I'm relieved that it's history. But this summer, as I wrapped up the 12th edition, the eugenics coverage took on a frightening new reality.

Will CRISPR fears fade with familiarity?
The first "test-tube baby" made headlines around the world in 1978, setting off intense debate on the ethics of researching human embryos and reproductive technologies. Every breakthrough since then has raised the same questions about "designer babies" and "playing God" – but public response has grown more subdued rather than more engaged as assisted reproductive technologies have become increasingly sophisticated and powerful.
