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

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.

genome sequence will help in developing protection against the disease. Robert Walgate discovers that it might - but perhaps not in the most obvious ways.

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

The CDC has given the OK to lift indoor mask mandates in much of the US, and a growing number of states no longer require face coverings in schools. But most experts agree that masks slow school spread of SARS-CoV-2, and whether now is the right time to allow teachers and students to unmask is a matter of debate.

Bacteria inhabit most tissues in the human body, and genes from some of these microbes have made their way to the human genome. Could this genetic transfer contribute to diseases such as cancer?

Metagenomic sequencing can help detect unknown pathogens, but its widespread use faces challenges.

FEATUREThe Ecology of Tumors   Courtesy of Nasa Ames Research CenterBy perturbing the microenvironment, wounds and infection may be key to tumor development.BY PARAIC A. KENNY, CELESTE M. NELSON, AND MINA J. BISSELLNo tumor is an island. Chemical and physical forces exerted by the diverse cellular populations that surround a tumor - its so-called microenvironment - shape development and progression. Manipulating these 'ecologi

The gastrointestinal tracts of people with major depressive disorder harbor a signature composition of viruses, bacteria, and their metabolic products, according to the most comprehensive genomic and metabolomic analysis in depression to date.

Scientists are using video games to tap the collective intelligence of people around the world, while doctors and educators are turning to games to treat and teach.
