[The Hebrew University of Jerusalem] Researchers have identified a simple form of molecular cooperation that may have helped life’s earliest building blocks become more stable and organized.

NASA Research Shows Path Toward Protocells on Titan
NASA research has shown that cell-like compartments called vesicles could form naturally in the lakes of Saturn’s moon Titan.
![[L] Absorbance data was acquired on a Perkin Elmer Synergy Neo2 plate reader equipped with monochromator optics. We first conducted spectral scanning from 380 nm to 740 nm (5 nm steps) to determine the wavelength of maximal OD increase (645 nm). Subsequent endpoint reads were acquired pre- and post-UV exposure at that single wavelength. Black columns – liposomes before the UV irradiation; grey columns – liposomes radiated with UV for 3 minutes. [R] Liposomes after 3 min of UV radiation. The top image shows liposomes shielded by cuvettes with distilled water, and the middle and bottom images show liposomes shielded by cuvettes with solutions of (NH4)5[Fe(C6H4O7)2] and FeCl3. -- biorxiv.org](https://i0.wp.com/astrobiology.com/wp-content/uploads/2024/05/Solutions-Of-Ferrous-Salts.png?resize=1200%2C717&ssl=1)

Solutions Of Ferrous Salts Protect Liposomes From UV Damage: Implications For Life Origin
Previously, we presented a hypothesis on the Darwinian evolution of liposomes that relies only on natural and ever-present phenomena: solar UV radiation, day/night cycle, gravity, and the formation of amphiphiles, […]
