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…)
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.
