Scientists have genetically modified isolated microbes for decades. Now, using CRISPR, they intend to target entire microbiomes.

Advances in sequencing technologies have finally allowed researchers to zero in on the genetic diversity underlying the incredible mating system of shelf fungi.

In the course of human history, something wonky happened to the levels of genetic diversity on the X chromosome -- scientists just can't agree on what. Two research teams reported conflicting reports about X chromosome diversity yesterday (Nov. 13) at the __American Society of Human Genetics__ linkurl:meeting;http://www.ashg.org/2008meeting/ in Philadelphia, with differing interpretations about human mating and migration. Because males only carry one X chromosome, sex-biased evolutionary forces

The Scientist spoke with microbiologist William Whitman about a new system of nomenclature for prokaryotic organisms that can’t be cultured.

Haydeh Payami helped uncover the genetic basis of Parkinson’s disease. Now, she hopes to find new ways to treat the disease by studying the gut microbiome.

George Church is at it again, this time using multiplex gene editing to create virus-proof cells, improve organ transplant success, and protect elephants.

Bioengineered bacteria sneak past solid tumor defenses to guide CAR T cells’ attacks.

Birds do it. Bees do it. We do it. But not without a physical, biochemical, and genetic price. How did the costly practice of sex become so commonplace?

Bettas were likely the first fish welcomed into human homes. Now, scientists are welcoming them into the lab to learn how genes dictate their appearance and behavior.
