Increased Asthma Found Among Iowa Children Living On Hog Farms New research conducted by investigators in the University of Iowa College of Public Health has found that the prevalence of asthma is elevated among children living on farms where swine are raised. Children living on swine farms where antibiotics are added to feed have a significantly higher prevalence of the respiratory disease, according to the UI study. Chronic Jet-lag Conditions Hasten Death In Aged Mice Researchers have found that aged mice undergoing weekly light-cycle shifts -- similar to those that humans experience with jet lag or rotating shift work -- experienced significantly higher death rates than did old mice kept on a normal daylight schedule over the same eight-week period. Batten Down The Hatches Against HIV: Carbon Nanotubes Transport Gene T A promising approach to gene therapy involves short DNA fragments (interfering RNA) that bind to specific genes and block their "translation"into the corresponding, disease-related protein. A stumbling block has been the efficient and targeted delivery of RNA into the cells. Researchers led by Hongjie Dai at Stanford University have sucessfully used carbon nanotubes as a "means of transport,"they write in "Angewandte Chemie." Wired's How To Wiki: Spot a Fake iPhone and Other Knock-Off Electronic Apple is undoubtedly counting on doting parents, love-blind fiances, and the spouses of the last remaining tech professionals who don't have one yet, to drop the $400 this holiday season necessary to bring an iPhone into their homes. And as with every status symbol, the iPhone has spawned a bevy of clones that look to take a bite out of Apple's market share either by undercutting a rather steep price point or by adding features and functionality where the iPhone left off. The WiredHow To Wiki gives a few tips on how to spot an iClone as well as presenting some examples of the ones that might be considered worthy alternatives. Everyone likes the underdog, so feel free to add a few iClones of your own. Polymers With Copper Show Promise For Implanted Sensors Developing chemical sensors that can be placed in the bloodstream or under the skin to continuously monitor oxygen, acidity (pH), or glucose levels is a major challenge for analytical chemists and biomedical engineers. The problem is, the body responds to these foreign objects in ways that interfere with their ability to accurately measure blood chemistry. Medication Orlistat Appears Helpful In Improving Weight Management For When combined with diet, exercise and behavioral therapy, orlistat, a drug that decreases fat absorption, appears helpful for improving weight management in obese adolescents, compared with placebo, according to an article in the June 15 issue of JAMA. Factors Responsible For Restart Of Meiotic Cycle Identified Scientists haave identified a pair of proteins that work in concert to restart the meiotic cycle of oocytes following a natural period of dormancy. The long-term implications of this work for human health and biology lie in a better understanding of how eggs are matured and released, knowledge that will have profound implications for treating infertility. Additionally, Polo kinase is strongly expressed in many types of tumor cells, so identifying a specific inhibitor for this protein may aid in the development of improved drugs for treating cancer. Nearly Unbreakable: Novel Nanoscale Construction Principle Prevents Bo Max Planck Scientists discover a novel construction principle at the nanoscale which prevents bones from breaking at excessive force. The Mortgage Market: What Happened? This April 2007 article provides an overview of how, as "nationwide real-estate boom of recent years goes bust, economists and regulators are questioning the role that mortgage lenders played in helping to create an overheated housing environment."Includes discussions of risky loans and types of adjustable-rate mortgages (ARMs), growth in subprime lending (loans to borrowers with poor credit), and unethical practices. From National Public Radio (NPR). Apple, AT&T Slapped With IPhone Monopoly Suits Two lawsuits accuse the companies of unfair business practices and antitrust violations based on their restrictions for using the iPhone.
