Salmonella use a “run-and-tumble” method of movement, including random direction changes, but how they move within the gut is not well understood. Now scientists believe they have identified a protein, McpC, that allows the bacteria to swim straight when they are ready to infect cells.

In a new study, scientists at Okayama University isolated cardiac stem cells and assessed their potential use as regenerative therapy in young patients with cardiac defects. The team not only showed the effectiveness of the cells in replenishing damaged tissues, but also revealed how this happens.

Researchers at University of California San Diego School of Medicine, in collaboration with Dutch scientists, have found that certain metabolites — small molecules produced by the process of metabolism — may be predictive indicators for persons at risk for recurrent major depressive disorder.

In a proof-of-principle study, Cornell researchers describe a new technique in which they analyzed environmental DNA – or eDNA – from water samples in Cayuga Lake to gather nuanced information about the presence of these invasive fish.

Anorexia is a debilitating eating disorder, and was long thought to be purely psychological. New research is challenging this by revealing that gut microbes may have a significant role in anorexia. A recent review examines the evidence that gut microbes can contribute to anorexia and may provide a new method to treat it.

Brain cells often cluster and grow together creating three-dimensional columns. While this pillar-like pattern of neurons is established, the exact mechanism behind its formation is still elusive. New research explains how molecules in the brain work in conjunction to create these architectural marvels of the brain.

Disrupting the metabolic pathway involved in the initiation, growth and progression of melanoma could lead to the development of new treatments for melanoma, according to new research published in PLoS One.

Research shows that stiffness in our tissues causes tension in our cells that impacts the innate immune system by upping its metabolism. The findings suggest the cellular tension likely sets off an inflammatory loop that contributes to the development of chronic diseases of aging.

Researchers have discovered the surprising propulsion system that enables these regenerative cells to migrate through surrounding tissue to repair damage.

A set of biomarkers not traditionally associated with cell fate can accurately predict how genetically identical cells behave differently under stress, according to a UT Southwestern study.
