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

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

The researchers who constructed the first reference genome for this critically endangered mollusk say it will assist restoration efforts.

Researchers discover that bacteria break down medicinal compounds for their nitrogen, solving a mystery that has vexed aquatic veterinarians for years.

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

Viruses abound in the world’s oceans, yet researchers are only beginning to understand how they affect life and chemistry from the water’s surface to the sea floor.

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

Jumping genes in bdelloid rotifers are tamped down by DNA methylation performed by an enzyme pilfered from bacteria roughly 60 million years ago, a study finds.

In the 20th century, animals such as mules and ligers that had parents of different species were considered biological flukes, but genetic sequencing is beginning to unravel the critical role of hybridization in evolution.

Researchers aim to unravel the molecular mechanisms by which a single genotype gives rise to diverse castes in eusocial organisms.
