On the origins of life: recreating cellular #metabolism
Researchers have reached a crucial step in understanding how living cells may have evolved from nonliving matter

eurekalert.org/news-releases/1

EurekAlert!On the origins of life: recreating cellular metabolismToday, scientists work to develop synthetic cells that mimic living cells, hoping to uncover clues that will help answer the question: how did life on Earth begin? In the past, researchers have focused on compartmentalization, but not on metabolism. Yet this cycle of building up and breaking down molecules is a critical aspect of how living cells respond to environmental stimuli, replicate and evolve. Now researchers from the University of California San Diego have designed a system that synthesizes cell membranes and incorporates metabolic activity.

#Nanostructures in the deep ocean floor hint at life’s origin

eurekalert.org/news-releases/1 #science #OriginOfLife #astrobiology #nanoworld

EurekAlert!Nanostructures in the deep ocean floor hint at life’s originResearchers from the RIKEN Center for Sustainable Resource Science (CSRS) in Japan and The Earth-Life Science Institute (ELSI) of Tokyo Institute of Technology have discovered inorganic nanostructures surrounding deep-ocean hydrothermal vents that are strikingly similar to molecules that make life as we know it possible. These nanostructures are self-organized and act as selective ion channels, which create energy that can be harnessed in the form of electricity. Published Sep. 25 in Nature Communications, the findings impact not only our understanding of how life began, but can also be applied to industrial blue-energy harvesting.
