A technique for growing sticky films of bacteria into elaborate microscopic images could reveal how potentially dangerous biofilms grow and transmit antibiotic resistance, and could lead to novel biomaterials or synthetic microbial communities.
A Norwegian biotech company called Phoenix Solutions AS is working with the Translational Genomics Research Institute (TGen), a Phoenix, Arizona-based biomedical research facility, to test the use of these pulsed sound waves to direct and focus cancer drug therapies.
Three tumor samples collected over time from a single patient shows how cancer evolves in response to treatment: A higher percentage of cancer stem cells in the final sample make a more aggressive disease.
University of Groningen physicists, and colleagues from Nijmegen and Hong Kong, have induced superconductivity in a monolayer of tungsten disulfide. By using an increasing electric field, they were able to show how the material turns from an insulator into a superconductor and then back into a 're-entrant' insulator again. Their results show the typical 'dome-shaped' superconducting phase, and finally provide an explanation for this phenomenon.
Japanese researchers have optimized the design of laboratory-grown, synthetic diamonds. This brings the new technology one step closer to enhancing biosensing applications, such as magnetic brain imaging. The advantages of this layered, sandwichlike, diamond structure are described in a recent issue of Applied Physics Letters.
Biomedical engineers from Duke University have demonstrated a new approach to making self-assembled biomaterials that relies on protein modifications and temperature. The hybrid approach allows researchers to control self-assembly more precisely, which may prove useful for a variety of biomedical applications, from drug delivery to wound-healing.
Researchers have taken a key step toward helping wildlife coexist more safely with wind power generation by demonstrating the success of an impact detection system that uses vibration sensors mounted to turbine blades.
A research team at the University of Delaware has developed technology to program strands of DNA into switches that turn proteins on and off. This technology could lead to the development of new cancer therapies and other drugs.
It defies conventional wisdom about semiconductors. It's baffling that it even works. It eludes physics models that try to explain it. This newly tested class of light-emitting semiconductors is so easy to produce from solution that it could be painted onto surfaces to light up our future in myriad colors shining from affordable lasers, LEDs, and even window glass.
Scientists are bringing precision medicine to rheumatoid arthritis for the first time by using genetic profiling of joint tissue to see which drugs will work for which patients, reports a new multi-site study. In the near future, patients won't have to waste time and be disappointed with months of ineffective therapy, scientists said. Currently $2.5 billion a year is wasted on therapy that doesn't work.
