The ability to share resources for the benefit of all members of a group may have driven ancient organisms to evolve from a unicellular to a multicellular state.

Goblet cells secrete mucins—which are key components of mucus—in a process that is regulated by calcium ions, which enter the goblet cells via a mechanism involving a channel protein called TRPM5.

The divergence of gene regulation during evolution in yeast traces phylogenetic distance with prominent changes being associated with changes in lifestyle and a whole genome duplication event.

Plants implement arithmetic division to optimize use of carbohydrate reserves and thus maintain metabolism and growth at night.

A modified form of Green Fluorescent Protein integrated into an ammonium transporter provides a sensor that can be used to monitor transport activity in vivo.

Cavin-3 is a tumor suppressor protein that inhibits Akt signaling, suppresses Warburg metabolism, promotes apoptosis, and protects against cachexia.

Melainabacteria, a candidate phylum related to Cyanobacteria, has been identified in gut and sediment samples by genomic analysis.

Mice with a mutation that disrupts the release of growth hormone show greatly increased lifespan, which can be further increased by caloric restriction.
