The transcription factor can also drive the opposite transition depending on which hormone activates it, according to a new study.

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

To understand how memories are formed and maintained, neuroscientists travel far beyond the cell body in search of answers.

Advances in the functional characterization of newly discovered microproteins hint at diverse roles in health and disease.

Clinical trials that target human endogenous retroviruses to treat multiple sclerosis, ALS, and other ailments are underway, but many questions remain about how these sequences may disrupt our biology.

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

Only recently have scientists directly witnessed this most pivotal of events in biology, thanks to new technology that allows them to observe the process in living cells. It’s teaching them a lot.

DNA passed to and from all kinds of organisms, even across kingdoms, has helped shape the tree of life, to a large and undisputed degree in microbes and also unexpectedly in multicellular fungi, plants, and animals.

The COVID-19 pandemic is still with us. Biomedical innovation has rallied to address that pressing concern while continuing to tackle broader research challenges.

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