Tomorrow's nonvolatile memory devices - computer memory that can retain stored information even when not powered - will profoundly change electronics, and Cornell University researchers have discovered a new way of measuring and optimizing their performance.
Using a novel microscopy method developed at the Institute, scientists from the Max Planck Institute for Medical Research in Heidelberg have now discovered that the distribution of the synapses between ganglion cells and interneurons follows highly specific rules. Only those dendrites that extend from the cell body of the amacrine cell in a direction opposite to the preferred direction of the ganglion cell connect with the ganglion cell.
In a new study, scientists showed that in people with diabetes, breathing ultrafine particles can activate platelets, cells in the blood that normally reduce bleeding from a wound, but can contribute to cardiovascular disease.
Another step has been taken in matter imaging. By using very short flashes of light produced by a technology developed at the national infrastructure Advanced Laser Light Source (ALLS) located at INRS University, researchers have obtained groundbreaking information on the electronic structure of atoms and molecules by observing for the first time ever electronic correlations using the method of high harmonic generation.
Alice A. Chen, a biomedical engineer and graduate student in the Harvard-MIT Division of Health Sciences and Technology (HST) and Harvard School of Engineering and Applied Sciences (SEAS), today received the prestigious $30,000 Lemelson-MIT Student Prize for her innovative applications of microtechnology to study human health and disease.
Since the middle of the 1990s a bright green fluorescent protein has been used in research laboratories worldwide. Protein designers at Technische Universitaet Muenchen (TUM) in Weihenstephan have now taken the existing fluorescent protein a step further: They have managed to incorporate a synthetic amino acid into the natural protein and thus to create a new kind of chimeric fluorescent bio-molecule by means of synthetic biology. By exploiting a special physical effect, the fluorescent protein glows in turquoise when excited with ultraviolet light and displays up to now unmatched properties.
The aim of this European funded Project called NanoDiaRA is to develop new nanotechnology to address major unmet clinical needs relating to the early detection and treatment of arthritic diseases like rheumatoid arthritis and osteoarthritis.
Scientists at AIST in Japan have produced high-purity carbon nanotubes (CNTs) with a random network structure by applying the super growth technique. This CNT structure exhibits rubber-like viscoelasticity in a temperature range of -196 to 1000 C.
A new architecture for quantum computation has emerged, according to a study published in Nature. Partial support for this study came from the EU-funded projects MICROTRAP (' Development of a pan-European Microtrap Technology capability for Trapped Ion Quantum Information Science') and SCALA ('Scalable quantum computing with light and atoms').
Researchers at National Nanotechnology Center, NANOTEC in Thailand, are doing research on the effects of the degree of quaternization, molecular weight and ratio of N-methylpyridinium and N,N,N-trimethyl ammonium moieties on bactericidal activity by introducing quaternization of N-(3-pyridylmethyl) chitosan derivatives.
