Go Figure: Math Model May Help Researchers with Stem Cell, Cancer Therapies

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.

*New University of Michigan research shows higher education, religion, income levels influence Arab American support of organ donation*

ANN ARBOR, Mich. – U.S. organ procurement organizations looking to increase donation rates among Arab Americans can turn to new University of Michigan Health System research for recruitment ideas.

U-M researchers identified various factors – from education and income levels to gender and religion – that may predict how members of this population view organ donation, says lead study author Aasim I. Padela, M.D., an emergency physician and a Robert Wood Johnson Foundation Clinical Scholar at the U-M Health System. (more…)

Around one in four Montrealers take some kind of anti-depressant, and according to new research, the drugs are passing into the waterways and affecting fish. The findings are internationally significant as the city’s sewage treatment system is similar to that in use in other major cities, and moreover, it is reputed to be the third largest treatment system in the world. Lead by Dr. Sébastien Sauvé at the University of Montreal’s Department of Chemistry and André Lajeunesse, a PhD candidate, the research team found that the drugs accumulate in fish tissues and are affecting the fish’s brain activity.

As NASA’s Voyager 2 spacecraft made the only close approach to date of our mysterious seventh planet Uranus 25 years ago, Project Scientist Ed Stone and the Voyager team gathered at NASA’s Jet Propulsion Laboratory, Pasadena, Calif., to pore over the data coming in.

Images of the small, icy Uranus moon Miranda were particularly surprising. Since small moons tend to cool and freeze over rapidly after their formation, scientists had expected a boring, ancient surface, pockmarked by crater-upon-weathered-crater. Instead they saw grooved terrain with linear valleys and ridges cutting through the older terrain and sometimes coming together in chevron shapes. They also saw dramatic fault scarps, or cliffs. All of this indicated that periods of tectonic and thermal activity had rocked Miranda’s surface in the past. (more…)

War, Plague No Match for Deforestation in Driving CO2 Buildup

Stanford, CA — Genghis Khan and his Mongol hordes had an impact on the global carbon cycle as big as today’s annual demand for gasoline. The Black Death, on the other hand, came and went too quickly for it to cause much of a blip in the global carbon budget. Dwarfing both of these events, however, has been the historical trend towards increasing deforestation, which over centuries has released vast amounts of carbon dioxide into the atmosphere, as crop and pasture lands expanded to feed growing human populations. Even Genghis Kahn couldn’t stop it for long. (more…)
