The archaeon Sulfolobus can be found near geysers like this one in Yellowstone
Dennis Grogan isolates cultures in the lab
A study of microbes that thrive in hot, acidic conditions has overturned a long-held view that species of micro-organisms do not differ by geographic location like other forms of life. The research by the University of Cincinnati and the University of California-Berkeley has just been published online by the journal Science.
When it comes to plant life and animal life, a species usually shows genetic differences in different parts of the world. For the tiny form of life known as micro-organisms, the opposite has been considered to be true – they don’t tend to differ by geographic location. That long-held view has been convincingly overturned in a study by University of Cincinnati and University of California, Berkeley, researchers focusing on a form of life that flourishes in extremely hot conditions.
Co-authors Dennis Grogan of the University of Cincinnati and Rachael J. Whitaker and John W. Taylor of Berkeley provide the most comprehensive proof to date that at least one species of micro-organism in different parts of the world does have genetic differences, if you look close enough. Whitaker, the principal author, focused on the archaeon Sulfolobus, found in acidic hot springs and flourishing at temperatures from 140-180 degrees Fahrenheit. She drew the vast majority of samples for her analysis from archives developed and stored at the University of Cincinnati Department of Biological Sciences under the leadership of Grogan. Whitaker analyzed the DNA of some 78 cultures from the United States, Eastern Russia and Iceland.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
