Gunnel Hänsel Petersson at Malmö University in Sweden has received an award for her studies of Cariogram, a computer program created in Malmö to assess patients’ risk of developing tooth decay, dental caries.
The program was constructed in 1997 by Professor Douglas Bratthall at the Faculty of Odontology at Malmö University College in Sweden. Today it has been translated into twelve languages and is attracting ever greater interest in other countries. Gunnel Hänsel Petersson’s study is the first evaluation of the program. “Caries occurs in a complicated interaction involving various factors built into the Cariogram Program. The program makes it easier for dentists to initiate the proper treatment to prevent caries,” explains Gunnel Hänsel Petersson.
There are a total of some ten risk factors whose respective importance is weighted in relation to each other: the number of earlier dental cavities, use of fluoride, the buffering capacity of the saliva, medicines, the number of bacteria in the mouth, diet, etc. The information is fed into the computer, and the program calculates the risk of caries. The patient’s risk profile is presented graphically in the form of a circle where sections of varying color and size represent the risk factors-the greater the green area, the greater the chance of avoiding caries.

Most natural and artificial surfaces are rough: metals and even glasses that appear smooth to the naked eye can look like jagged mountain ranges under the microscope. There is currently no uniform theory about the origin of this roughness despite it being observed on all scales, from the atomic to the tectonic. Scientists suspect that the rough surface is formed by irreversible plastic deformation that occurs in many processes of mechanical machining of components such as milling.

Researchers at Chalmers University of Technology, Sweden, recently completed a 5-year research project looking at how to make fibre optic communications systems more energy efficient. Among their proposals are smart, error-correcting data chip circuits, which they refined to be 10 times less energy consumptive. The project has yielded several scientific articles, in publications including Nature Communications.
Streaming films and music, scrolling through social media, and using cloud-based storage services are everyday activities now.
After helping develop a new approach for organic synthesis -- carbon-hydrogen functionalization -- scientists at Emory University are now showing how this approach may apply to drug discovery. Nature Catalysis published their most recent work -- a streamlined process for making a three-dimensional scaffold of keen interest to the pharmaceutical industry.
"Our tools open up whole new chemical space for potential drug targets," says Huw Davies, Emory professor of organic chemistry and senior author of the paper.
