Models help UD researchers calculate best dosage for osteoporosis treatment
They may seem rigid and set in their ways, but your bones are actually under constant construction and deconstruction. They give up their nutrient treasures (calcium) to the body and then rebuild in a constant give-and-take sort of rhythm. (more…)
Researchers have developed a new mathematical model that accurately describes the evolution of ancient empires.
The computer model can predict with 65% accuracy where and when the largest complex societies arose in human history.
The research, which suggests that intense warfare is the evolutionary driver of large complex societies, is published in the journal Proceedings of the National Academy of Sciences (PNAS). It was carried out by researchers from the University of Exeter in collaboration with University of Connecticut and the National Institute for Mathematical and Biological Synthesis (NIMBioS) in the US.

Martin Gartzman sat in his dentist’s waiting room last fall when he read a study in Education Next that nearly brought him to tears.
A decade ago, in his former position as chief math and science officer for Chicago Public Schools, Gartzman spearheaded an attempt to decrease ninth-grade algebra failure rates, an issue he calls “an incredibly vexing problem.” His idea was to provide extra time for struggling students by having them take two consecutive periods of algebra.
Gartzman had been under the impression that the double-dose algebra program he had instituted had only marginal results, but the study he read indicated otherwise. (more…)
*A project that helps students with low vision take notes wins the U.S. Imagine Cup’s preeminent software design category.*
REDMOND, Wash. – April 12, 2011 – When David Hayden’s team won the U.S. Imagine Cup’s prestigious category Monday, it was a victory for him as a student with low vision, and for all students with reduced vision across the world.
Hayden and Team Note-Taker from Arizona State University (ASU) won the Software Design category after competing in Microsoft’s U.S. Imagine Cup finals over the weekend. His team will advance to compete in the Imagine Cup world finals in July. (more…)
GAINESVILLE, Fla. — The difficult task of sorting and counting prized stem cells and their cancer-causing cousins has long frustrated scientists looking for new ways to help people who have progressive diseases.
But in a development likely to delight math teachers, University of Florida researchers have devised a series of mathematical steps that accomplishes what the most powerful microscopes, high-throughput screening systems and protein assays have failed to do — assess how rapidly stem cells and their malignant, stemlike alter egos increase their numbers.

LOS ANGELES — Oct. 20, 2010 —
Microsoft Corp. today announced it is providing the Partnership for Los Angeles Schools with a more than $1 million grant to purchase new software and hardware for the two schools at the Felicitas and Gonzalo Mendez Learning Center. This grant will help bring state-of-the-art technology to the campus, helping bridge the technology gap of this underserved community. The grant also includes a $50,000 cash donation portion that will provide for ongoing technical support, teacher and student training, curriculum, and mentoring opportunities for students to learn about and explore careers. The goal is to create an instructional model that can be replicated and scaled throughout Los Angeles Unified School District and elevate teacher and student technology skills, thereby preparing youth for the competitive Los Angeles and U.S. job market. Microsoft education executives and Los Angeles Mayor Antonio Villaraigosa announced the sizeable donation this morning at a press conference at Mendez, where city leaders, school leaders, teachers and students saw a preview of the new software and technology.
