Researchers report the function of reverse-twisting DNA

Normally, the two strands of the DNA double helix wind around each other in a right-handed spiral. However, there is another conformation called Z-DNA in which the strands twist to the left. The function of Z-DNA has remained ...

Does genetic testing pose psychosocial risks?

For the last quarter century, researchers have been asking whether genetic information might have negative psychosocial effects. Anxiety, depression, disrupted relationships, and heightened stigmatization have all been posited ...

CRISPR baby mutation significantly increases mortality

A genetic mutation that a Chinese scientist attempted to create in twin babies born last year, ostensibly to help them fend off HIV infection, is also associated with a 21% increase in mortality in later life, according to ...

Researchers identify 'beauty spots' in the genome

Genes play a role in determining the beauty of a person's face, but that role varies with the person's sex, according to a new study by Qiongshi Lu and colleagues at the University of Wisconsin-Madison, published 4th April ...

'Jumping genes' drive many cancers

Mistakes in DNA are known to drive cancer growth. But a new study, from Washington University School of Medicine in St. Louis, heavily implicates a genetic phenomenon commonly known as "jumping genes" in the growth of tumors.

Genetics

New biomarker links cancer progression to genome instability

Our DNA is under constant attack. The delicate molecule that contains our genetic information is extremely vulnerable to everything from environmental agents, such as radiation, to the chemicals in the air we breathe and ...
