POPSNew way to make stem cells is safe Hochedlinger's team used a much more harmless virus, called an adenovirus, to carry into the cells the four transformative genes, called Oct4, Sox2, Klf4 and c-Myc. They used mouse skin cells and also liver cells from fetal mice and got both types to look and act like iPS cells As the cells divide, they dilute the virus until it disappears, he said. But the genetic changes remain. To test the cells they made chimeras --- a blend of two separate animals. They injected their newly made cells into mouse embryos and when the pups were born, they carried visible evidence that the cells had indeed transformed them And so far, these chimeric mice have not developed any tumors If it works, some day doctors may be able to make tailor-made transplants to treat diseases in people by removing a few cells, transforming them in the lab and transplanting the new tissue or organs back in

POPSWhat Happens if You Fall Into a Black Hole? If you fell into a large enough black hole, your last moments would be a little bit like being on the inside of a distorted, one-way mirror. No one outside would be able to see you, but you'd have a view of them. Meanwhile, the gravitational pull would bend the light weirdly and distort your last moments of vision

POPSplant refugees The researchers used two different climate models that predict changes in temperature and rainfall through 2100 to make their projections -- one that assumes higher and another that assumes lower greenhouse gas emissions. What the models did suggest, however, is that reducing greenhouse gases would have a significant impact on native species

POPSGlobal Database of Quotas for Women
Obstacles to women's political participation exist throughout the world in prevailing social and economic regimes, as well as in existing political structures. In 2005, the representation of women reached nearly 16 percent globally. Although this total has increased in recent years, the minimal progress globally means that the ideal of parity remains a long way off. Given the slow rate at which the representation of women is increasing, various methods -- such as electoral quotas -- have been proposed or implemented to address the present gender imbalance in decision-making. Consequently, governments and political parties have experimented with different types of quotas. As the debate about the use of quotas as a tool to increase the political participation of women gains momentum, International IDEA and Stockholm University are collaborating on a research project leading to the production of a comparative knowledge and resources on their implementation and impact.

POPSPhotoGallery / Wall Paintings in the Afghan Region of Bamiyan The world was in shock when in 2001 the Taliban destroyed two ancient colossal Buddha statues in the Afghan region of Bamiyan. Behind those statues, there are caves decorated with precious paintings from 5th to 9th century A.D. The caves also suffered from Taliban destruction, as well as from a severe natural environment, but today they have become the source of a major discovery. Scientists have proved, thanks to experiments performed at the European Synchrotron Radiation Facility (ESRF), that the paintings were made of oil, hundreds of years before the technique was “invented” in Europe.
