Schematic of micro- and nanopropellers in hyaluronan gels. The polymeric mesh structure hinders the larger helices from translating effectively, whereas smaller propellers with a diameter close to the mesh size can pass through the network without being affected by the macroscopic viscoelasticity caused by the entangled polymer chains. If you thought that the most impressive … Continue reading

via University of Cambridge A new technique which uses light like a needle to thread long chains of particles could help bring sci-fi concepts such as cloaking devices one step closer to reality. A new method of building materials using light, developed by researchers at the University of Cambridge, could one day enable technologies that … Continue reading
Lithium (Photo credit: Absolute Chaos) A team of Stanford University researchers, including former Energy Secretary Steven Chu, believes it has achieved the “holy grail” of lithium battery design: an anode of pure lithium that could boost the range of an electric car to 300 miles. Lithium-ion batteries are one of the most common types of … Continue reading
Zinc porphyrin dyes were used to create solar cells that can absorb both visible and near-infrared light.© 2014 A*A*STAR Institute of Materials Research and Engineering Dye-sensitized solar cell absorbs a broad range of visible and infrared wavelengths Dye-sensitized solar cells (DSSCs) rely on dyes that absorb light to mobilize a current of electrons and are … Continue reading
Cancer Targeted Treatments from Space Station Discoveries (NASA, International Space Station, 02/26/14) (Photo credit: NASA’s Marshall Space Flight Center) A modified anticancer drug can simultaneously target tumor sites and show whether or not it is working Cancer drugs can be modified to specifically target tumor sites to help personalize cancer treatment. And while it is … Continue reading
via EPSRC An innovative ‘trigeneration’ system fuelled entirely by raw plant oils could have great potential for isolated homes and businesses operating outside grid systems both in the UK and abroad. Developed by a consortium led by Newcastle University and funded by the Engineering and Physical Sciences Research Council (EPSRC), through theRCUK Energy Programme, the … Continue reading
via Aarhus Water is used around the world for the production of electricity, but new research results show that there will not be enough water in the world to meet demand by 2040 if the energy and power situation does not improve before then. Two new reports that focus on the global electricity water nexus … Continue reading
An international team of researchers led by the University of Arizona has sequenced the complete genome of African rice. The genetic information will enhance scientists’ and agriculturalists’ understanding of the growing patterns of African rice, as well as enable the development of new rice varieties that are better able to cope with increasing environmental stressors … Continue reading
Butterfly on a flower (Photo credit: aivas14) Long before humans figured out how to create colors, nature had already perfected the process â think stunning, bright butterfly wings of many different hues, for example. Now scientists are tapping into those secrets to develop a more environmentally friendly way to make colored plastics. Their paper on … Continue reading
