Researchers have identified and characterized a new type of RNA protein called THOR that plays a role in cancer development — and could serve as a target for drug development.

A new study indicates a benefit for all young colon cancer patients to undergo genetic testing. But with more than half of them exhibiting no family history, will insurers cover the tests?

How a visualization — and a new understanding — of a class of “defender proteins” may help scientists fight HIV infection.

A PCR-based approach to a frontier of the human genome could speed discovery in chromosome-based diseases and birth defects.

Cancer can damage undifferentiated naive T cells, which keeps the fighter cells from doing their job.

Personalized dosing of omega-3 fatty acids decreases prostaglandin E2 in the colon, but the beneficial effects are smaller in overweight people, research finds.

Engineered polymeric materials known as hydrogels represent a new way to heal intestinal damage — a process that one day might be applied to other injured organs.

Helpful forms of E. coli may trigger steps that keep infections out, new experiments in dish-grown gut organoids show.

Suppressive Treg cells become even more suppressive when they die, a new study finds.

Fruit flies are far more than a kitchen nuisance. Learn how the pests and other tiny critters are helping researchers find major clues to human disease.

By harnessing massive amounts of data on activity within and between snippets of DNA, researchers aim to one day reprogram both healthy and diseased cells.

Learn how a powerful combination of a new protein inhibitor and a chemotherapy drug lead to triple negative breast cancer cell death in mice.

A discovery in hormone-producing cells could lead to a better understanding of diseases related to misfolded proteins.

Donated tumor tissue from a 5-year-old brain cancer patient uncovers the key and early role of a less-understood genetic mutation in the cancer’s fatal course.

A new understanding of the interaction among multidrug-resistant bacteria, and how antibiotics affect them, could lead to better infection prevention.
