(Northwestern University) It's hard to study something with any rigor if the subject can't be produced uniformly and efficiently. Researchers who study double-walled carbon nanotubes find themselves in just this predicament. The problem is that current techniques for synthesizing double-walled carbon nanotubes also produce unwanted single- and multi-walled nanotubes. Northwestern University researchers now offer a clever solution: They used a tech... More

The loop quantum cosmology (LQC) theory is poised to make testable predictions. If they are verified, the big bang will give way to a big bounce and we will finally know the quantum structure of space-time. Instead of a universe that emerged from a point of infinite density, we will have one that recycles, possibly through an eternal series of expansions and contractions, with no beginning and no end.

New protective coatings developed at the University of Illinois heal over their own scratches with no external intervention, protecting the underlying metal from corrosion. The self-healing elements, in a paint additive, are enclosed in microcapsules that rip open when the coating is scratched. (Source: http://www.technologyreview.com/business/21812/?a=f)

Microsoft wants to use its ESP program to model the entire world as accurately as possible, embedding "real" physics into the system. Microsoft ESP is a visual simulation platform that to engage users in immersive experiences with very realistic land, sea and air environments by integrating with, for example, Virtual Earth. The model will grow over time and become more realistic. (Source: http://www.redmonk.com/jgovernor/2008/09/25/living-in-de... More

A project called nanoTouch, developed at Microsoft Research, tackles the challenges of adding touch sensitivity to ever-shrinking displays. A gadget would have a front that is entirely a display, a back that is entirely touch- sensitive, and a side that features buttons.Perceptive Pixel describes software that recognizes how hard a user is pressing a surface. If they press hard on an image of, say, a playing card and slides it along the display to... More

(PhysOrg.com) -- Carbon, the active ingredient in charcoal, is normally not considered a fire retardant, but researchers at the National Institute of Standards and Technology have determined that adding a small amount of carbon nanofibers to the polyurethane foams used in some upholstered furniture can reduce flammability by about 35 percent when compared to foam infused with conventional fire retardants.
