Cervical cancer is highly curable when caught early. But in a third of cases, the tumor responds poorly to therapy or recurs later, when cure is much less likely.
Quicker identification of non-responding tumors may be possible using a new mathematical model developed by researchers at the Ohio State University Comprehensive Cancer Center-Arthur G. James Cancer Hospital and Richard J. Solove Research Institute.
The model uses information from magnetic resonance imaging (MRI) scans taken before and during therapy to monitor changes in tumor size. That information is plugged into the model to predict whether a particular case is responding well to treatment. If not, the patient can be changed to a more aggressive or experimental therapy midway through treatment, something not possible now.

Data-mining technology is an increasingly popular way to search for patterns, correlations and trends within crime statistics, genomics data and other enormous amounts of information, and now UT Dallas researchers have created a repository of tools intended to further boost this young field.
The Data Mining Tool Repository provides researchers and developers with a number of useful data sets and tools, according to Dr. Latifur Khan, an associate professor of computer science, who developed the repository in conjunction with Dr. Mehedy Masud, a postdoctoral fellow, and students and other collaborators.

A new study co-written by a University of Illinois expert in math education suggests that incorporating technology in high school-level geometry classes not only makes the teaching of concepts such as congruency easier, it also empowers students to discover other geometric relationships they wouldn’t ordinarily uncover when more traditional methods of instruction were used.
Gloriana González, a professor of curriculum and instruction in the College of Education at Illinois, says when students used dynamic geometry software they were more successful in discovering new mathematical ideas than when they used static, paper-based diagrams.

Scientists have made many discoveries about the origins of our 13.7 billion-year-old universe. But many scientific mysteries remain. What exactly happened during the Big Bang, when rapidly evolving physical processes set the stage for gases to form stars, planets and galaxies? Now astrophysicists using supercomputers to simulate the Big Bang have a new mathematical tool to unravel those mysteries, says Daniel R. Reynolds, assistant professor of mathematics at SMU.

Constantinos Daskalakis applies the theory of computational complexity to game theory, with consequences in a range of disciplines.
Computer scientists have spent decades developing techniques for answering a single question: How long does a given calculation take to perform? Constantinos Daskalakis, an assistant professor in MIT’s Computer Science and Artificial Intelligence Laboratory, has exported those techniques to game theory, a branch of mathematics with applications in economics, traffic management — on both the Internet and the interstate — and biology, among other things. By showing that some common game-theoretical problems are so hard that they’d take the lifetime of the universe to solve, Daskalakis is suggesting that they can’t accurately represent what happens in the real world.
