To understand how this type of cancer spreads, it's crucial to characterize the interactions between cancer cells and their 3-D environment. Researchers at Fox Chase Cancer Center have developed a novel, 3-D culture system that mimics the environment surrounding these cancer cells. This model could be used to test new anticancer drugs capable of inhibiting the spread of IBC tumors.http://www.eurekalert.org/pub_releases/2012-12/fccc-rdn120612.php Sat, 08 Dec 2012 00:00:00 ESThttp://www.eurekalert.org/pub_releases/2012-12/fccc-rdn120612.phpThe promising investigational targeted therapy ibrutinib and its mechanism of silencing gene communication pathways critical to the development of cancer may be an effective way to combat chronic lymphocytic leukemia, according to studies presented today at the 54th Annual Meeting of the American Society of Hematology.http://www.eurekalert.org/pub_releases/2012-12/asoh-iat120512.php Sat, 08 Dec 2012 00:00:00 ESThttp://www.eurekalert.org/pub_releases/2012-12/asoh-iat120512.phpCareful observers of the new "Black Marble" images of Earth at night released this week by NASA and the National Oceanic and Atmospheric Administration have noticed bright areas in the western part of Australia that are largely uninhabited. Why is this area so lit up, many have asked? Away from the cities, much of the night light observed by the NASA-NOAA Suomi NPP satellite in these images comes from wildfires.http://www.eurekalert.org/pub_releases/2012-12/nsfc-wlu120712.php Fri, 07 Dec 2012 00:00:00 ESThttp://www.eurekalert.org/pub_releases/2012-12/nsfc-wlu120712.phpMassive crevasses and bendable iceaffect stability of Antarctic ice shelf,CU-Boulder research team finds.http://www.eurekalert.org/pub_releases/2012-12/uoca-mca120712.php Fri, 07 Dec 2012 00:00:00 ESThttp://www.eurekalert.org/pub_releases/2012-12/uoca-mca120712.phpAs large organisms, trees face some remarkable challenges, particularly regarding long-distance transport and communication. In addition to moving water and nutrients from their roots to their leaves, they must also integrate cell-to-cell communication over large areas. Furthermore, to function as a single, cohesive organism, they must be able to effectively and efficiently send vital substances long distances along a network of cells, sieve-tubes, and vessels. But how effective is this cell-to-cell communication and how far can such solutes travel?http://www.eurekalert.org/pub_releases/2012-12/ajob-lst120712.php Fri, 07 Dec 2012 00:00:00 ESThttp://www.eurekalert.org/pub_releases/2012-12/ajob-lst120712.phpIn a new study, published in the Proceedings of the National Academies of Science, MU School of Medicine scientists Yi Lai and Dongsheng Duan have discovered the missing pieces to a muscular dystrophy puzzle that could ultimately lead to a therapy and, potentially, a longer lifespan for patients suffering from the disease.http://www.eurekalert.org/pub_releases/2012-12/uom-amd120712.php Fri, 07 Dec 2012 00:00:00 ESThttp://www.eurekalert.org/pub_releases/2012-12/uom-amd120712.phpEconomic growth will rise to 3 percent in 2013 and 2014, while unemployment will drop to 7.3 percent by December of 2013, NJIT Leir Research Professor William V.
