Natural Selection Has Strongly Influenced Recent Human Evolution, Stud
The most detailed analysis to date of how humans differ from one another at the DNA level shows strong evidence that natural selection has shaped the recent evolution of our species, according to a study by researchers from Cornell University, Celera Genomics and Celera Diagnostics published in the Oct. 20 issue of the journal Nature. Safer, Self-Extinguishing Cigarettes Designed By Manufacturers Sold In
Smoldering cigarettes are the leading cause of fire deaths in the United States causing more than 800 deaths per year. The technology to create safer cigarettes exists. To meet a New York safety standard that went into effect June 28th, 2004, the major US cigarette manufacturers have altered the design of cigarette brands sold in that state. Finding ET
Research in the field of exobiology relies on one of the biggest assumptions we make about the universe - that we are not alone, that there could be life on worlds other than the Earth.However, one assumption we should not make about life elsewhere in the universe is that it uses the same templates and [...] National Register Evaluation of New Orleans Drainage System, Orleans P
1999 report about the history of "the modern New Orleans drainage system [which] represents a unique technological solution to natural conditions that have played an important role in the settlement and expansion of the city. The system was designed in 1895, and construction of the system began in 1897."The report recommends selected pumping stations be considered individually eligible for nomination to the National Register of Historic Places. Includes a bibliography and numerous images. Nocturnal Dialysis Improves Heart Disease In Patients With End-stage K
Cardiovascular disease contributes to the high annual mortality rate (15-20%) in conventional hemodialysis patients. This study found a five-fold decrease in endothelial progenitor cells, which contribute to repair of blood vessel walls, in patients on conventional dialysis compared to patients on night hemodialysis and to healthy participants. Night hemodialysis patients also matched healthy participants on blood pressure and left ventricular mass scores, compared with day-time dialysis patients in the Toronto General Hospital-St. Michael's Hospital study. Fast-Acting Carbs May Hasten Vision Loss Over Time
Consuming higher-than-average amounts of carbohydrates that cause blood sugar levels to spike and fall rapidly could be a risk factor for central vision loss with aging. Diets high in carbohydrates that are quickly digested and absorbed, resulting in a rapid rise in blood sugar levels, are considered high-glycemic-index diets. Diet Can Provide Protection Against Development Of Certain Cancers, Ne
With cancer, researchers don't believe "you are what you eat"; that disease is always a direct result of what is, or what isn't, on your dinner plate. But studies into the association between diet and cancer show that food can have an impact in preventing cancer, or in reducing the aggressiveness of the disease.

A New Generation Of Medicinal Products
CNRS (France) researchers have developed a novel synthetic process for bio degradeable materials that could be used instead of traditional medication in the form of tablets, capsules or syrups. This study was published on 27 December 2006 in the Journal of the American Chemical society. Buckyballs Used As 'Passkey' Into Cancer Cells
Rice University chemists and Baylor College of Medicine pediatric scientists have discovered how to use buckyballs as passkeys that allows drugs to enter cancer cells. Research in the January 21 issue of the journal Organic and Biomolecular Chemistry, describes how the researchers mimicked the techniques used by some viruses to introduce non-toxic bits of buckyball-containing protein into both neuroblastoma and liver cancer cells.
