Yes MAM: How Organelles Talk To Each Other
Using a new technique to observe inter-organelle communication in live cells, researchers have identified the proteins that form signaling hubs known as mitochondria-associated membranes.
An Electrifying Development For Cancer Treatment
Scientists in Japan have optimized pulsed electric fields to disrupt calcium metabolism in cancer cells.
A Trio Of Photoreceptors Orchestrate Cell Aggregation
Having multiple photoreceptors allows cyanobacteria to coordinate complex processes such as cell aggregation, scientists say.
The Chemistry Underlying Learning In Worms
Using a simple behavioral test, scientists found two neuromodulatory signaling molecules underlying non-associative learning in C. elegans.
Mapping Out The Ligand-Receptor Network
Autocrine signaling may be more common than previously thought, according to the first large-scale map of communication between over 140 different cell types.
Typhoid Bacteria Linked To Gallbladder Cancer
The findings suggest that treating Salmonella Typhi with antibiotics would lower the incidence of gallbladder in India.
From Periphery To The Nucleus
A previously unidentified perinuclear actin ring could be the link between mechanosensing at the cell periphery and DNA regulation in the nucleus.
Blue Light Changes Bacterial Lifestyle
The photoreceptor SesA enables cyanobacteria sense blue light and produce cellulose to avoid light damage.
