Anpassungsfähige Stimulation könnte Patienten mit neurologischen Erkrankungen wie Parkinson deutlich entlasten

Könnten beim Einsatz tiefer Hirnstimulation zur Behandlung von Parkinson potenzielle Nebenwirkungen mithilfe eines so genannten geschlossenen Regelkreises vermieden werden, der sich individuell an die Symptome der Patientin oder des Patienten anpasst? Mit dieser Frage beschäftigen sich der Neurowissenschaftler Dr. Ioannis Vlachos und seine Kollegen Taskin Deniz, Prof. Dr. Arvind Kumar und Prof. Dr. Ad Aertsen in einer aktuellen Studie, die in der Fachzeitschrift „PLoS Computational Biology“ erschienen ist.

The days of self-assembling nanoparticles taking hours to form a film over a microscopic-sized wafer are over. Researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) have devised a technique whereby self-assembling nanoparticle arrays can form a highly ordered thin film over macroscopic distances in one minute.

Ting Xu, a polymer scientist with Berkeley Lab’s Materials Sciences Division, led a study in which supramolecules based on block copolymers were combined with gold nanoparticles to create nanocomposites that under solvent annealing quickly self-assembled into hierarchically-structured thin films spanning an area of several square centimeters. The technique is compatible with current nanomanufacturing processes and has the potential to generate new families of optical coatings for applications in a wide number of areas including solar energy, nanoelectronics and computer memory storage. This technique could even open new avenues to the fabrication of metamaterials, artificial nanoconstructs that possess remarkable optical properties. (more…)

“Simming” a mile in others’ shoes

Scott Magelssen has had more lives than an accident-prone cat. He’s been a waiter in a logging camp. An anthrax victim. A Mexican migrant trying to cross into the U.S. A slave seeking freedom on the Underground Railroad. An observer during an attack on an Iraqi village.

It’s all in a day’s work for Magelssen, a UW associate professor of drama, who has participated in a variety of interactive simulations for his upcoming book, “Simming” to be published in June by University of Michigan Press. The book explores the impact of simulations and the potential of such immersive environments to promote social change. (more…)
