[13/01/2012] Similar to the way pavement, softened by a hot sun, will slow down a car, graphene—a one-atom-thick sheet of carbon with wondrous properties—slows down an object sliding across its surface. But stack the sheets and graphene gets more slippery, say theorists at the National Institute of Standards and Technology (NIST), who developed new software to quantify the material's friction.

[10/01/2012] The hardest substance in the human body is moved by its strongest muscles: When we heartily bite into an apple or a schnitzel, enormous strengths are working on the surface of our teeth. “What the natural tooth enamel has to endure also goes for dentures, inlays or bridges“, glass chemist Professor Christian Rüssel of the Friedrich Schiller University Jena (Germany) says.

[16/12/2011] Researchers at Helmholtz Zentrum Berlin (HZB) have developed a new microscope for high spatial resolution X-ray spectroscopic studies. While conventional X-ray spectroscopy has so far fallen short of resolving single nanoparticles, the X-ray microscope at HZB’s synchrotron source BESSY II succeeds by using high-brilliancy X-rays.

Are All Hip Replacement Implants the Same?
( Source: COMPAMED.de )
[07/12/2011] More than 270,000 Americans get hip replacement surgeries every year - a number that is projected to double in the next decade as the population ages. With various options for implants, including metal-on-polyethylene, metal-on-metal and ceramic-on-ceramic, there have been questions about which kind works best.
