Protein Accelerates Breast Cancer Progression In Animal Models
Scientists have shown for the first time that a cytokine called pleiotrophin stimulates the progression of breast cancer in both animal and cell culture models. The study, which tested three separate models to determine the role of inappropriate expression of pleiotrophin, found that it produced striking increases in aggressiveness of the breast cancer cells themselves. Glaucoma Finding: Experiments Show How Increased Pressure In Eye Leads
New research from Children's Hospital Boston and the Massachusetts Eye and Ear Infirmary may help explain how glaucoma causes blindness, revealing the chain of events that ultimately damage the optic nerve, preventing visual information from getting to the brain. The study indicates possible targets for intervention, including one for which there are already approved drugs. Carnegie Mellon Robotized SUV Wins DARPA Urban Challenge
A self-driving SUV called Boss made history by driving swiftly and safely while sharing the road with human drivers and other robots. The feat earned Carnegie Mellon University's Tartan Racing first place in the DARPA Urban Challenge. Officials of the Defense Advanced Research Projects Agency (DARPA) declared Boss the winner of the event, which pitted 11 autonomous vehicles against each other on a course of suburban/urban roadways. The first-place prize includes a $2 million cash award. New Way To Measure Ancient Ocean Temperatures Refined
A new thermometer measures seawater temperature dependent changes in the cell wall composition of archeabacteria. Climate reconstructions should always be based on comparisons of several types of parallel measurements to prevent unexpected scientific blunders, according to researchers. Determining the surface seawater temperatures in oceans and coastal waters is essential for the reconstruction of historic climate changes and changes in ocean currents. This information is, in turn, vital for perfecting current climate models. Putting Relativity To The Test, NASA's Gravity Probe B Experiment Is O
Dropping Religious Activities Linked To Increased Anxiety In Women
For many, religious activity changes between childhood and adulthood, and a new study finds this could affect one's mental health. Women who had stopped being religiously active were more than three times more likely to have suffered generalized anxiety and alcohol abuse/dependence than women who reported always having been active. Conversely, men who stopped being religiously active were less likely to suffer major depression when compared to men who had always been religiously active. Drug Reduces Unscheduled Trips To Doctor For Childhood Asthma Attacks
Young children with attacks of sporadic, recurring asthma who were treated with the prescription drug montelukast by their parents had fewer unscheduled trips to the doctor, missed less days from school or childcare, and caused their parents to take fewer days off work for their care. [Odd] A Romanian couple has named their son Yahoo as a sign of gratitu
Daily Libertatea said on Thursday Cornelia and Nonu Dragoman, both from Transylvania, met and decided they were meant for each other following a three-month relationship over the net.They married and had a baby this Christmas, whom they decided to name after one of the worldwide web's most popular portals."We named him Lucian Yahoo after my father and the net, the main beacon of my life,"Cornelia Dragoman was quoted as saying. Little Creatures, Big Blooms
The San Francisco area is one of the most biologically productive areas in US waters. But with global warming, says Natural Sciences and Engineering Research Council grantee Vera Pospelova, those waters are going to change. Pospelova studies sedimentary records of dinoflagellates -- plankton creatures, eaten by fish, that depend on the sun for their survival. There are dozens of species of these creatures, but the ones that produce toxic blooms concern her the most. In the Realms of the Unreal
