Researchers have discovered that ascidians measure time to adulthood by accumulating cyclic adenosine monophosphate (cAMP), ensuring a reliable timing of metamorphosis. The study's findings provide insights into time-measurement mechanisms in other organisms and may aid in aquaculture and marine biofouling control.
Researchers discovered that 15-deoxy-prostamide-J2 induces ER stress-mediated apoptosis selectively in tumor cells, reducing melanoma growth. The molecule activates PERK, IP3R, and the mitochondrial permeability transition pore, leading to cell death.

A rare genetic disorder called anhidrosis has been linked to a mutation in the ITPR2 gene, which controls calcium release in sweat glands. The study, led by Katsuhiko Mikoshiba and Niklas Dahl, found that a single nucleotide change in the DNA code impairs sweat production, leading to hyperthermia risk.
