Suspicion of melanoma: In the future, doctors can pull out a new type of microscope to get to the bottom of suspicious changes in the skin. It provides a high-resolution image of skin areas of any size "“ and so quickly that you can hold it in your hand without blurring the resulting picture.Are the dark spots on a patient's skin malignant? In the future, doctors will be able to take a closer look at suspicious blemishes using a new microscope "“ with results in just a few fractions of a...

When you suffer a heart attack, a part of your heart dies. Nerve cells in the heart's wall and a special class of cells that spontaneously expand and contract "“ keeping the heart beating in perfect synchronicity "“ are lost forever. Surgeons can't repair the affected area. It's as if when confronted with a road riddled with potholes, you abandon what's there and build a new road instead.Needless to say, this is a grossly inefficient way to treat arguably the single most important organ...

ST. LOUIS, May 19, 2011 /PRNewswire/ -- Belden Inc. (NYSE: BDC), a global leader in signal transmission solutions for mission-critical applications, has introduced its PPO UL AWM Hook-up Wire as an environmentally-friendly alternative to traditional PVC-insulated and XLPE-insulated hook-up wire. PPO Wire also meets or exceeds the electrical and thermal characteristics of traditional products, while being smaller in diameter, lighter in weight, stronger and more durable. (Logo:...

Scientists from the University of Sheffield have developed pigment-free, intensely colored polymer materials, which could provide new, anti-counterfeit devices on passports or banknotes due to their difficulty to copy.The polymers do not use pigments but instead exhibit intense color due to their structure, similar to the way nature creates color for beetle shells and butterfly wings.These colors were created by highly ordered polymer layers, which the researchers produced using block...

New research paves way for the nanoscale self-assembly of organic building blocks, a promising new route towards the next generation of ultra-small electronic devices.Ring-like molecules with unusual five-fold symmetry bind strongly to a copper surface, due to a substantial transfer of charge, but experience remarkably little difficulty in sideways diffusion, and exhibit surprisingly little interaction between neighbouring molecules. This unprecedented combination of features is ideal for the...

Iowa State University's Malika Jeffries-EL says she's studying doing structure-property studies so she can teach old polymers new tricks.Those tricks improve the properties of certain organic polymers that mimic the properties of traditional inorganic semiconductors and could make the polymers very useful in organic solar cells, light-emitting diodes and thin-film transistors.Conductive polymers date back to the late 1970s when researchers Alan Heeger, Alan MacDiarmid and Hideki Shirakawa...

BETHLEHEM, Pa., April 28, 2011 /PRNewswire/ -- Particle Sciences Inc. (PSI), a leading pharmaceutical CRO, and Celanese EVA Performance Polymers, a leading supplier of ethylene vinyl acetate (EVA) into pharmaceutical applications, are working together to streamline the development of drug-eluting devices. Building on years of collaboration, Particle Sciences and Celanese EVA Performance Polymers are working to provide Particle Sciences with preferred access to VitalDose(TM) EVA polymer in...

Discovery of self-corrective healing process for polymer detailed this week in the journal NatureImagine you're driving your own new car--or a rental car--and you need to park in a commercial garage. Maybe you're going to work, visiting a mall or attending an event at a sports stadium, and you're in a rush. Limited and small available spots and concrete pillars make parking a challenge. And it happens that day: you slightly misjudge a corner and you can hear the squeal as you scratch the side...
