Columbia team finds that gastrin plays significant role in helicobacter-induced stomach cancer
A group led by Columbia University Medical Center's Timothy Wang, M.D., has studied the role of Helicobacter infection in the development of stomach cancer and found that the hormone gastrin, which stimulates secretion of gastric acid, plays a key role in the development of Helicobacter-induced stomach cancer, and may have distinct effects on carcinogenesis in different parts of the stomach.

How mitochondria get their membranes bent
Mitochondria are the powerhouses of cells. Underneath their smooth surface they harbor an elaborately folded inner membrane. It holds a multitude of bottleneck like invaginations, which expand into elongated cavities (cristae).

Can't compete on dung? Try mating on apple pomace
In the mating world of yellow dung flies, large, brawny males almost always get the girl. However, a new study suggests that smaller males rule if presented with an opportunity to woo females when they are not hanging out on cow dung.
