Silver nanoparticles by design

A team in India has tested the antibacterial activity of silver nanoparticles generated in the presence of the common microbes Streptomyces species. They used ultraviolet spectroscopy and X-ray diffraction to assess the structures of the AgNPs. Electron microscopy revealed the particles to be spherical and 30 nanometres in diameter. The particles were active against Escherichia coli and other microbial pathogens. However, parallel tests against a laboratory breast cancer cell line showed them to be even more toxic against such cells and to open up the possibility of using such biological AgNPs in a new type of anticancer therapy.

Research Pick: Shadow puppetry - "Quantitative analysis of the puppet shapes in Ngayogyakarta Wayang Kulit"

Ngayogyakarta Wayang Kulit is an ancient performance art form. Intricately carved leather puppets are commonly used to project a shadow on to an illuminated screen as a story or fable is relayed to the audience. The art form may encompass traditional, spiritual, or other types of story.

Such cultural importance is this art form from Indonesia that Wayang Kulit is UNESCO-listed. Researchers have now used various techniques to analyze the shapes of the shadow puppets and the characters that they represent with a view to facilitating conservation of the art form.

“We found that various pairs of physical variables can be used to analyze the puppet shapes: the puppet level of details, the puppet surface area, the puppet perimeter length and the puppet height. Our results demonstrate that we can classify the different types of puppet characters using the puppet shapes,” the team concludes.

Research Pick: Metro accessible - "A simple method to assess walkability around metro stations"

The success of any metropolitan transport service, the metro, relies on accessibility for the commuters and others who use it. If they can access it on foot or on non-powered wheeled transport, such as a bicycle, then it should be a success because it will allow people to get to and from their destination without the added pressure of vehicular congestion at either end of their metro journey. Researchers in Qatar have looked at the “walkability” of proposed metro stations in Doha. Their method of analysis is facile but provides important clues as to how planners might improve a metro system and make it even more accessible, usable, and useful.

Research Picks: Dam you! - "Uncertainty assessment in the results of inverse problems: applied to damage detection in masonry dams"

Masonry dams are a critical component in civil engineering infrastructure across the world acting as the stalwart of water reservoirs for drinking and hydroelectric power generation. Given this, there is a need to understand the stresses and strains that such dams face especially when structural damage occurs during and after an earth tremor earthquake. Researchers in Germany have devised a method that can reveal localised damage and identify the degree to which a masonry dam has been compromised under a given scenario. Given that lives may depend on the integrity of such a dam, it is critical to understand the changes they may undergo and the means by which they might be repaired.

Research Pick: Open source movement - "Open source innovation: what makes it move?"

Researchers in Brazil are hoping to understand what motivates the so-called open source movement particularly when it comes to open source innovation (OSI). They have carried out field studies of international companies that have adopted the OSI approach.

Their study confirms earlier explanations of the motivations but also adds to our understanding in areas beyond the software industries where open source has been a common ethos for much longer than other industries. Fundamentally, OSI offers businesses a way to break free strategically from the constraints of more conventional approaches to innovation.

The team suggests that the open strategy proposed by the OSI model could empower companies to up their competitive game.

Research Pick: How not to go viral - "The spread pattern on Ebola and the control schemes"

The spread of the viral disease Ebola is a major worldwide health concern. Recent outbreaks in Africa have ultimately been well controlled, but a new emergence could occur and cause significant loss of life not only to those local to the epidemic but across the globe as the disease can spread so quickly with international air travel.

Researchers in China have investigated the logistics and dynamics of how Ebola spreads with the hope that their model can inform a future response to an outbreak quickly and effectively before it spreads.

Moreover, the approach ensures minimal cost, which is important given that emergence of the lethal hemorrhagic disease commonly occurs in undeveloped and developing nations.
