Public Release: 9-Feb-2010
 Nature PhotonicsHigh-performance microring resonator developed by INRS researchers A new, more efficient low-cost microring resonator for high speed telecommunications systems has been developed and tested by Professor Roberto Morandotti's INRS team in collaboration with Canadian, American, and Australian researchers. This technological advance capitalizes on the benefits of optical fibers to transmit large quantities of data at ultra-fast speeds. The results of the team's work, just published in the prestigious journal Nature Photonics, will facilitate the transition from electronic to optical communications. Contact: Gisèle Bolduc

Nature MaterialsCaltech researchers develop nanoscale structures with superior mechanical properties Researchers at Caltech have developed a way to make some notoriously brittle materials ductile -- yet stronger than ever -- simply by reducing their size. The work could eventually lead to the development of innovative, superstrong, yet light and damage-tolerant materials. These new materials could be used as components in structural applications, such as in lightweight aerospace vehicles that last longer under extreme environmental conditions and in naval vessels that are resistant to corrosion and wear.

Human MutationComprehensive study using bioinformatics predicts the molecular causes of many genetic diseases It is widely known that genetic mutations cause disease. What are largely unknown are the mechanisms by which these mutations wreak havoc at the molecular level, giving rise to clinically observable symptoms in patients. Now a new study using bioinformatics, led by scientists at the Buck Institute for Age Research, reports the ability to predict the molecular cause of many inherited genetic diseases. These predictions have led to the creation of a web-based tool available to academic researchers who study disease.

ScienceResearchers reveal 3-D structure of bullet-shaped virus with potential to fight cancer, HIV A recent UCLA study demonstrates that with advanced imaging technique, the vesicular stomatitis virus can be modified to serve as an anti-cancer agent because it displays high selectivity in killing cancer cells while sparing normal cells. It can also be engineered as a potent vaccine against HIV/AIDS.

Perfectly shaped solid components When metals are shaped, the materials they are made of are often damaged in the process. One cause of this is excessive press force, which cracks and perforates the material. By running simulations on a PC, research scientists can now calculate how to avoid component defects.

Genome ResearchMethod of the future uses single-cell imaging to identify gene interactions Cellular imaging offers a wealth of data about how cells respond to stimuli, but harnessing this technique to study biological systems is a daunting challenge. In a study published online in Genome Research, researchers have developed a novel method of interpreting data from single-cell images to identify genetic interactions within biological networks, offering a glimpse into the future of high-throughput cell imaging analysis.

ScienceElectrons on the brink: Fractal patterns may be key to semiconductor magnetism A Princeton-led team of scientists has observed electrons in a semiconductor on the brink of the metal-insulator transition for the first time. Caught in the act, the electrons formed complex patterns resembling those seen in turbulent fluids, confirming some long-held predictions and providing new insights into how semiconductors can be turned into magnets. The work also could lead to the production of smaller and more energy-efficient computers.

SciencePrinceton scientist makes a leap in quantum computing Princeton University's Jason Petta has demonstrated a method that alters the properties of a lone electron without disturbing the trillions of electrons in its immediate surroundings. The feat is essential to the development of future varieties of superfast computers with near-limitless capacities for data.

Nature BiotechnologyNTU researchers complete the world's first in-depth study of the malaria parasite genome Groundbreaking research done at Singapore's Nanyang Technological University's School of Biological Sciences could lead to the development of more potent drugs or a vaccine for malaria. Assistant Professor Zbynek Bozdech and his team of researchers, including graduate students and post-doctorals from SBS' Division of Genomics & Genetics, have scored a world first in successfully using transcriptional profiling to uncover hitherto unknown gene expression (activity) patterns in malaria.

Journal of Molecular BiologyBreakthrough by Danish scientists in preventing maternal malaria Researchers at the University of Copenhagen have become the first in the world to synthesize the entire protein that is responsible for life-threatening malaria in pregnant women and their unborn children. The protein known as VAR2CSA enables malaria parasites to accumulate in the placenta and can therefore potentially be used as the main component in a vaccine to trigger antibodies that protect pregnant women against malaria. The research team is now planning to test the efficacy of the protein-based vaccine on humans. Contact: Sandra Szivos
