How do you improve on plastic, a modern material that has already changed the way we do everything from design medical devices to build cars? Embed it with specialized proteins called enzymes, says Shekhar Garde, assistant professor of chemical engineering at Rensselaer Polytechnic Institute.
"Such protein-enhanced plastics might someday be able to act as ultra-hygienic surfaces or sensors to detect the presence of various chemicals," says Garde. These types of materials could have a wide range of applications, for example, in the security or medical industries.
Proteins require water to function, however. Nonwatery environments do not provide the driving force necessary to keep proteins in their normally intricately folded state; unfolded, the molecules cease to function. To learn what it takes to successfully integrate proteins into a dry substance such as plastic, Garde and his graduate student Lu Yang use molecular dynamics (MD) simulations to create a computer model of the proteins and study the molecules in both watery and non-watery environments such as organic solvents. They are working in collaboration with Jonathan S. Dordick, the Howard P. Isermann ’42 Professor of Chemical Engineering, who conducted the initial protein research.

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
