Natural Radiocarbon Distribution in the Deep Ocean
We present for the first time objectively mapped natural radiocarbon (14C) abundance in the global deep ocean using mostly new measurements from the World Ocean Circulation Experiment (WOCE). Compared to earlier data from the Geochemical Ocean Sections Study, the new data number almost seven times more. Also, the WOCE data collected during the 1990s have sufficient spatial coverage to make obje...

Alexander Sulakvelidze, Chief Scientist at Intralytix and one of its co-founders, says phages are a very safe and natural way of protecting food against bacteria. “The concept of using phages for improving food safety is based on simply applying phages back onto the foods in the right concentration, at the right place, and at the right time,” Sulakvelidze explains. “Thus, applying lytic phages ...
متن کاملOptical Detection of Radiocarbon Dioxide in Natural and Enriched Abundance
Radiocarbon optical detection, based on infrared laser spectroscopy, was proposed more than 30 years ago [1]. Indeed, radiocarbon dioxide (CO2) has strongly absorbing rovibrational bands at 4.5 μm, making it an ideal target molecular species for radiocarbon sensing, even below its natural abundance (about 1 part per trillion). In our group, we have developed a new high-sensitivity spectroscopic...
