Nanoengineered Concrete Could Cut Carbon Dioxide Emissions
While government leaders argue about the practicality of reducing world emissions of carbon dioxide, researchers are seeking ways to make it happen. One group of engineers at MIT is focusing its work on the nanostructure of concrete, the world's most widely used material. The production of cement, the primary component of concrete, accounts for 5 to 10 percent of the world's total carbon dioxide emissions; the process is an important contributor to global warming. Azureus' HD Vids Trump YouTube
The file-sharing software company has a new platform for crystal-clear, high-definition videos over BitTorrent. Those blurry, pixelated videos on YouTube may soon be a relic of the past. By Michael Calore. Token Resuscitation Attempts On Hopelessly Ill Patients Prolong Suffer
Lack of legal clarity and clinical guidelines can put health-care professionals in a very difficult position when it comes to resuscitating hopelessly ill patients. But using "slow codes"-- where resuscitation is carried out too slowly to be effective -- can prolong death and suffering, according to a recent review. Gallery: Macworld IPod Gadgets

John Tams, who dons beard, boots and red suit to work in a cafe's Christmas grotto, said he wanted to give something back to the community... Thriving Hybrid Salamanders Contradict Common Wisdom
A new study not only has important findings for the future of California tiger salamanders, but also contradicts prevailing scientific thought about what happens when animal species interbreed. They found that more of the hybrid young survived in the wild than did young of the native or the introduced species -- quite a surprise, since animal hybrids are usually less fit than their parents ("hybrid vigor"is largely limited to plant crosses). Penn Surgeons Use Completely Robotic Surgery To Treat Prostate Cancer
Prostate cancer is the second leading cause of death among American men. It is estimated that one in six males will develop the disease during his lifetime. However, promising new treatment options have been developed to help combat this threatening disease. One of the most innovative of these treatments is robotic-assisted laparoscopic prostatectomy (removal of the prostate). The University of Pennsylvania Health System is currently one of only a handful of facilities across the country offering this minimally invasive, high-tech treatment. Forests Of Endangered Tropical Kelp Discovered
Forests of a species of kelp previously thought endangered or extinct in deep waters near the Galapagos Islands has just been discovered. This discovery has important implications for biodiversity and the resilience of tropical marine systems to climate change. Drink Less Rather Than Shower Less To Save Water
Balancing Act, a world first that has been developed for the Australia economy by scientists from CSIRO and the University of Sydney, looks across 135 industry sectors of the Australian economy and quantifies the impacts and contributions across ten social, environmental, and financial indicators. Most Adults With Conditions That Increase Cardiovascular Disease Risk
Nearly three-fourths of American adults with conditions such as coronary heart disease, stroke, diabetes or others that raise their risk for cardiovascular complications also have hypertension (high blood pressure), according to a new report. Although about 75 percent of these individuals are being treated for hypertension, only one-third to one-half are reaching blood pressure goals.
