Fossilized organic molecules of green sulfur bacteria are helping to unlock secrets of what may have been a period of helter-skelter climate change and mass kills of sea life during the Jurassic Period some 150-160 million years ago.
The fossils were found in sedimentary rock commonly used to make house bricks in England, quarried from what is called the Oxford Clay Formation.
The findings are reported in the May issue of the journal Geology (now online to subscribers.) Fabien Kenig, associate professor of earth and environmental sciences at the University of Illinois at Chicago, is the articles lead author. Contributors include John Hudson of the University of Leicester, Jaap Sinninghe Damsté of the Royal Netherlands Institute for Sea Research and Brian Popp of the University of Hawaii.

With a quantum coprocessor in the cloud, physicists from Innsbruck, Austria, open the door to the simulation of previously unsolvable problems in chemistry, materials research or high-energy physics. The research groups led by Rainer Blatt and Peter Zoller report in the journal Nature how they simulated particle physics phenomena on 20 quantum bits and how the quantum simulator self-verified the result for the first time.
Many scientists are currently working on investigating how quantum advantage can be exploited on hardware already available today. Three years ago, physicists...
'Quantum technologies' utilise the unique phenomena of quantum superposition and entanglement to encode and process information, with potentially profound benefits to a wide range of information technologies from communications to sensing and computing.
However a major challenge in developing these technologies is that the quantum phenomena are very fragile, and only a handful of physical systems have been...
