Aquaculture's Growth Seen As Continuing - An assessment concludes that despite well-publicized concerns about some harmful effects of aquaculture, the technique may, when practiced well, be no more harmful to biodiversity than other food production systems. Aquaculture production of aquatic animals now accounts for about a third of the total supply and will probably remain the most rapidly increasing food production system worldwide through 2025, according to the author.... 'Relocation' Plan Of Metastatic Cancer Cells Uncovered - Few things are as tiresome as house hunting and moving. Unfortunately, metastatic cancer cells have the relocation process down pat. Tripping nimbly from one abode to another, these migrating cancer cells often prove far more deadly than the original tumor. Although little has been known about how these rogue cells choose where to put down roots, researchers have now learned just how nefarious they are.... Deaths From Lung Cancer Could Be Reduced By Better Policies To Control Indoor Radon, Experts Urge - About 1,100 people each year die in the UK from lung cancer related to indoor radon, but current government protection policies focus mainly on the small number of homes with high radon levels and neglect the 95 percent of radon-related deaths caused by lower levels of radon, according to a study.... Packing A Lunch For Preschoolers May Not Be A Good Idea - Approximately 13 million children in the United States eat three or more meals and snacks each day at one of the country?s 117,000 regulated child-care centers. Due to increasing cost of food preparation and storage, more and more of these centers are requiring parents to provide food for their children.... Computer Game 'Tetris' May Help Reduce Flashbacks To Traumatic Events - Playing 'Tetris' after traumatic events could reduce the flashbacks experienced in post-traumatic stress disorder (PTSD), preliminary research by Oxford University psychologists suggests.... Nerve Cells In The Brain And Spinal Cord Sense Pain Caused By Physical Insult - Researchers have shown that the protein COX2 in mouse nerve cells in the central nervous system (CNS) is crucial for hypersensitivity to pain caused by the physical insult associated with inflammation, but not pain caused by the heat associated with inflammation. As pain caused by physical insult is a major symptom of postoperative and arthritic inflammation, it seems that COX2 in nerve cells in the CNS is central to the pain that accompanies these conditions.... Novel Glioblastoma Mouse Model Developed - Researchers have developed a versatile mouse model of glioblastoma -- the most common and deadly brain cancer in humans -- that closely resembles the development and progression of human brain tumors that arise naturally....
