Researchers used knockout mouse models created by gene editing to reveal that the miRNA miR-146b, like miR-146a, is involved in the development of cancers, with them having similar but not identical effects. The knockout mice should help in the fight against cancers involving miRNA dysregulation.

Researchers exploring a buried lake "twice the size of Manhattan" drilled through 3,500 feet of ice to learn more about the mysterious body of water — and made a stunning discovery along the way.

Scientists now have an idea of how an ancient creature likely moved thanks to a nearly 300-million year-old-fossil skeleton and a set of well-preserved footprints.

CNN anchor John King raised a question on Friday about whether or not second lady Karen Pence should be denied housing and Secret Service protection because works at a Virginia school that does not permit gay men and lesbians to be teachers.

Tens of thousands of striking Los Angeles teachers rallied outside City Hall on Friday, joined by parents and students as "productive" contract talks resumed behind closed doors after a marathon negotiating session the day before.

Researchers have developed a way to dramatically enhance the sensitivity of nuclear magnetic resonance spectroscopy (NMR), a technique used to study the structure and composition of many kinds of molecules, including proteins linked to Alzheimer's and other diseases.

Brief, text-based, self-administered exercises can significantly increase in-the-moment happiness for adults recovering from substance use disorders, report researchers.

A study in rodents found that the brain's cerebellum -- known to play a role in motor coordination -- also helps control the brain's reward circuitry. Researchers found a direct neural connection from the cerebellum to the ventral tegmental area (a brain area long known to be involved in reward processing and encoding). The findings shed light on the brain circuits critical to the affective and social dysfunction seen across multiple psychiatric disorders.
