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.

Optical quantum computers can revolutionize computer technology. A team of researchers led by scientists from Münster University and KIT now succeeded in putting a quantum optical experimental set-up onto a chip. In doing so, they have met one of the requirements for making it possible to use photonic circuits for optical quantum computers.
Optical quantum computers are what people are pinning their hopes on for tomorrow’s computer technology – whether for tap-proof data encryption, ultrafast...
The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has been developing various applications for OLED microdisplays based on organic semiconductors. By integrating the capabilities of an image sensor directly into the microdisplay, eye movements can be recorded by the smart glasses and utilized for guidance and control functions, as one example. The new design will be debuted at Augmented World Expo Europe (AWE) in Berlin at Booth B25, October 18th – 19th.
“Augmented-reality” and “wearables” have become terms we encounter almost daily. Both can make daily life a little simpler and provide valuable assistance for...
With the help of artificial intelligence, chemists from the University of Basel in Switzerland have computed the characteristics of about two million crystals made up of four chemical elements. The researchers were able to identify 90 previously unknown thermodynamically stable crystals that can be regarded as new materials. They report on their findings in the scientific journal Physical Review Letters.
