Researchers have known for some time that women who experience weakened hea stanley website rt function in the months before and after childbirth a condition known as peripartum cardiomyopathy recover more quickly than any other group of heart failure patients. Now, a team of researchers from Mt. Sinai School of Medicine thinks it may know why. The researchers have demonstrated that when a pregnant mouse suffers from a heart attack, her fetus will actually dona stanley cups te cells that can migrate to mom heart before differentiating into different types of cardiac cells, aiding in the heart regenerative processes. 80 Beats ; Valerie Ross explains how the researchers discovered the helpful fetuses: The researchers started with two lines of mice: normal mice and mice genetically engineered to express green fluorescent protein GFP , which glows a distinctive green when exposed to blue light, in their cells. They mated n stanley cup uk ormal female mice with GFP-producing male mice. This meant that half the resulting fetuses had the GFP gene, too, making their cells glow, too. Twelve days later-a little less than two-thirds of the way through a normal mouse pregnancy-the researchers gave half the pregnant mice heart attacks. When the scientists examined the female mice heart tissue two weeks after the heart attacks, they found lots of glowing green tissue-cells that came from the fetus-in the mom heart. Mice who had heart attacks had eight times as many cells from the fetus in th Visj io9 Weekend Roundup
It no secret that the U.S. education system is hurting, especially when it comes to science teachers. Public schools are chronically underfunded, and the most talented college graduates shy away from entering the teaching profession when its future seems so grim. But hope isn ;t lost. A pioneering program at New York American Museum of Natural History aims to make the future better for science teachers by starting a new kind of Master of Arts program in science teaching. Starting this June, the program will provide 50 teachers-in-training with a thorough education in Earth science, along with a year classroom work experience, all while paying a mo stanley trinkflaschen dest stipend. The deadline for applications to the program is January 31 yes, you can still apply , and there will be an open house for interested students who want to talk to faculty and staff this Saturday, January 7, from 12-4 at the museum. Funded in part by the National Science Foundation, and in part by New York State, this teaching cr stanley uk edential program is what AMNH Senior VP Lisa Guggenheim hopes will be the first of many of stanley cup fered by alternative institutions like museums who can supplement what universities already do. She told io9 that AMNH has been partnering with teachers for almost a decade, working with schools and teachers to provide everything from course materials to teacher training.
