Self-assembled nano-sized probes allow Penn researchers to see tumors through flesh and skin
Nano-sized particles embedded with bright, light-emitting molecules have enabled researchers to visualize a tumor more than one centimeter below the skin surface using only infrared light. A team of chemists, bioengineers and medical researchers based at the University of Pennsylvania and the University of Minnesota has lodged fluorescent materials called porphyrins within the surface of a polyme...Atmosphere may cleanse itself better than previously thought
A research team from Purdue University and the University of California, San Diego has found that the Earth’s atmosphere may be more effective at cleansing itself of smog and other damaging hydrocarbons than was once thought. Scientists, including Joseph S. Francisco, have learned that some naturally occurring atmospheric chemicals react with sunlight more effectively than previously thou...Self-assembled DNA buckyballs for drug delivery
DNA isn't just for storing genetic codes any more. Since DNA can polymerize -- linking many molecules together into larger structures -- scientists have been using it as a nanoscale building material, constructing geometric shapes and even working mechanical devices. Now Cornell University researchers have made DNA buckyballs -- tiny geodesic spheres that could be used for drug delivery an...New insight into autoimmune disease: Bacterial infections promote recognition of self-glycolipids
The immune system is a complex and powerful weapon that provides protection against bacteria and viruses that, if left unchecked, would wreak havoc throughout the human body. The ability of the immune system to recognize the body's own tissues is essential, but sometimes the immune system loses the ability to distinguish "self" from potentially harmful invaders. This can lead to autoimmune diseas...Shampoo detergent added to paint makes surfaces self-sterilizing
Adding a common ingredient in shampoo to paints and varnishes can create self-sanitizing coatings for frequently touched surfaces in public buildings that continue killing germs for months, according to research conducted by a multi-state consortium of high school students and retirees. Working through the website science-projects.com, 10 students from New York, Texas and Virginia joined t...Corning Cryo Vial Rack, PC, Holds 30 Self-Standing Vials, Non-Sterile from Sigma-Aldrich

Description:Self Closing Forceps...Technology spurs great service, full service, and self-service.
The phrase full service used to mean a gas station where attendants would fill your tank, check your fluids, and clean your windshield. Today, it means that a bank provides you with a wide range of alternatives to seeing a local teller things like Internet banking, ATM card cards, and telephone-driven interactive voice response (IVR) systems. Weve entered the decade of self-service. C...Self-Drying Vacuum Pumps... the solution for applications producing condensation
Where gases with high moisture content must be evacuated during vacuum drying operations, condensate may collect in the vacuum pump head. Consequently, the pump may not perform properly and may take more time to evacuate the designated volume. New, self-drying pumps...Doyle signs "self-dealing" bill

The common belief that medicinal formulations based on alternative and complementary medicine are tested before they can be approved for use has been accounted for misuse of these products by Australian citizens // .More than 50% of the Australian population have been using alternative medicines in some form or the other, according to a study conducted recently. "This is in contrast to...Physicians Consider Self-Prescribing Ethical
Most physicians consider writing a prescription for themselves "ethical," but only about half see it as "healthy," and few consider it "necessary". Medical student Robert Wroblewski and others at the University of Minnesota, Duluth, surveyed 300 urban and rural physicians to determine general attitudes towards self-prescription. An earlier study had indicated that about half of all reside...Heart may pull Cells from Body to Self-repair
According to researchers, after analysis of cells in men with transplanted hearts from female donors, the proof is the piling up that the heart may be able toregenerate itself at least somewhat by recruiting cells from elsewhere in the body.// Traditionally, it was thought that once cells were damaged or dead, they could not be replaced or repaired by the heart. By looking at the Y chr...Self control makes stress response easy
According to pshycologists, believing that one can control a stressful situation makes it easier on your heart and circulation.// Exposure to a stressful situation is potentially damaging to health because it increases blood pressure and resistance to blood flow. Over time, these responses may accumulate to increase the risk of heart disease. But the level of the physiological response t...Self-Threading MONOKA (Fayet-Bernard Ritleng Type, PVP coating)
