Researchers discover brain's switching system used in information processing and storing of memories

A team of scientists has uncovered a system in the brain used in the processing of information and in the storing of memories--akin to how railroad switches control a train's destination. The findings offer new insights into how the brain functions.

Experimental model shows how topological defects in the mesothelium affect ovarian cancer metastasis

Ovarian cancer devastates more than 20,000 women in the U.S. every year, due in part to its tendency to evade detection and present after metastatic spread. A key element to slowing metastasis is understanding the mechanisms of how tumor cells invade tissues.

Melanoma mutations result from a chemical conversion in DNA fueled by sunlight, study reports

The mutations that give rise to melanoma result from a chemical conversion in DNA fueled by sunlight - not just a DNA copying error as previously believed, reports a study by Van Andel Institute scientists published today in Science Advances.

Researchers develop two complementary bladder models to study UTIs

Urinary tract infections (UTIs) are among the most common bacterial infections. They usually require treatment with antibiotics, and almost a quarter of treated cases lead to recurrent infection.

Study provides new understanding on function of mitofusin 2 in cellular energy metabolism

Mitofusin 2 is a key protein in the regulation of the physiology of mitochondria ─cellular organelles that produce energy─ involved in several neurodegenerative and cardiovascular diseases, as well as in cancer.

New study shines light on how plant cells perceive and respond to mechanical forces

Minuscule tunnels through the cell membrane help cells to perceive and respond to mechanical forces, such as pressure or touch. A new study in the journal Science is among the first to directly investigate what one type of these mechanosensitive ion channels is doing in the tip-growing cells in moss and pollen tubes of flowering plants, and how.

Study examines the role of programmed cell death ligands in skin immune responses

T cells are a crucial part of the human adaptive immune system. In response to a foreign invader in the body, various subsets of T cells are responsible for several functions that include killing infected cells and secreting signaling molecules called cytokines that tell other immune cells where to go and what to do.
