...ure cells that surround or form them. The question arose partly because of the number of nuclei found in each cell. The tumor cells each have a single nucleus, while developed muscle tissue contains many nuclei up to several hundred. The muscle cells are surrounded by satellite cells, which can develop i...Scientists: Wildlife corridors benefit plant biodiversity, native plants

Over the five years, the unconnected patches lost about 10 native species. Meanwhile, the corridors seemed to have no impact on the number ...New company will seek drugs against diabetes and cancer
... Emerging Technologies in St. Louis. The company arose from a collaboration between Cagan and Baranski, who is also an endocrinologist at Barnes-Jewish Hospital. Cagan showed Baranski a method developed in his lab for determining if a drug could correct abnormal development in the eyes of fruit flies.
