Protecting cells from their neighbors
Almost all organisms evolve from a single cell, a fertilised egg. In the first hours after fertilisation, the fate of its future development is determined. It is dictated by the separation of cells that will become sperm and ovules - germ cells-, from the remaining cells, which will be responsible...Scientists decoding genomic sequences of H1N1 using isolates from outbreak in Argentina

PHILADELPHIA Researchers from the Centers for Disease Control and Prevention (CDC) found that survival among women with ovarian cancer is influenced by age of menarche and total number of lifetime ovulatory cycles. This finding suggests that hormonal activity over the course of a woman's lifet...Clean fuels could reduce deaths from ship smokestacks by 40,000 annually
Rising levels of smokestack emissions from oceangoing ships will cause an estimated 87,000 deaths worldwide each year by 2012 almost one-third higher than previously believed, according to the second major study on that topic. The study says that government action to reduce sulfur emissions from ...'Normal' cells far from cancer give nanosignals of trouble
A new Northwestern University-led study of human colon, pancreatic and lung cells is the first to report that cancer cells and their non-cancerous cell neighbors, although quite different under the microscope, share very similar structural abnormalities on the nanoscale level. The findings, ob...Scientists are learning more about big birds from feathers
WEST LAFAYETTE, Ind. - Catching adult eagles for research purposes is no easy task, but a Purdue University researcher has found a way around the problem, and, in the process, gathered even more information about the birds without ever laying a hand on one.

We can only marvel at the way that dolphins, whales and porpoises scythe through water. Their finlike flippers seem perfectly adapted for maximum aquatic agility. However, no one had ever analysed how the animals' flippers interact with water; the hydrodynamic lift that they generate, the drag tha...CWRU receives $5 million from Ohio Third Frontier Commission

A team of researchers from the University of Cadiz has confirmed that zinc, copper and lead are present at high levels in the water and sediments of the Huelva estuary, and have studied how some of these heavy metals are transferred to fish. The study shows that zinc, cadmium and copper accumulate...New method separates cancer cells from normal cells
The vast majority of cancer deaths are due to metastasis, the spread of cancer cells from its primary site to other parts of the body. These metastatic cells tend to move more than their non-metastatic variants but this movement is poorly understood.
