MathCloud.jpgMath class may never be the same. When asked to create a right triangle, high-school students in four rural North Carolina school districts now turn to their laptops and begin stretching lines and tracing points. Once completed, students can drag the triangle in multiple directions and observe its behavior. Shifting a line eliminates the hallmark 90 degree angle. The right triangle morphs into an isosceles triangle.

Princeton engineers have made a breakthrough in an 80-year-old quandary in quantum physics, paving the way for the development of new materials that could make electronic devices smaller and cars more energy efficient.

By reworking a theory first proposed by physicists in the 1920s, the researchers discovered a new way to predict important characteristics of a new material before it's been created. The new formula allows computers to model the properties of a material up to 100,000 times faster than previously possible and vastly expands the range of properties scientists can study.

UCLA's Jeffrey Brantingham works with the Los Angeles Police Department to analyze crime patterns. He also studies hunter-gatherers in Northern Tibet. If you tell him his research interests sound completely unrelated, he will quickly correct you.

Data suggest symmetry may ‘melt’ along with protons and neutrons

Scientists at the Relativistic Heavy Ion Collider (RHIC), a 2.4-mile-circumference particle accelerator at the U.S. Department of Energy’s Brookhaven National Laboratory, report the first hints of profound symmetry transformations in the hot soup of quarks, antiquarks, and gluons produced in RHIC’s most energetic collisions. In particular, the new results, reported in the journal Physical Review Letters, suggest that “bubbles” formed within this hot soup may internally disobey the so-called “mirror symmetry” that normally characterizes the interactions of quarks and gluons.

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.

Dr. Latifur KhanData-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.
