A research team of Ehime University paved a way to achieve unexplored III-V semiconductor nanostructures. They grew branched GaAs nanowires with a nontoxic Bi element employing characteristic structural modifications correlated with metallic droplets, as well as crystalline defects and orientations. The finding provides a rational design concept for the creation of semiconductor nanostructures with the concentration of constituents beyond the fundamental limit, making it potentially applicable to novel efficient near-infrared devices and quantum electronics.

Polycyclic heteroaromatic molecules are a highly useful class of organic materials. In this study, synthesis of a new azacoronene, in which both pyrrole and azulene moieties are circularly fused, was achieved in just three steps. This new azacoronene exhibited multistep reversible oxidations under electrochemical and chemical conditions. Formation of an aromatic 22π-electron conjugation and a tropylium cation (6π-electron conjugation) in the dicationic state played a key role in stabilizing this cationic species.

DNA amplification -- a molecular "photocopying" technique where genetic material is replicated -- has many applications in scientific research, forensic science, and medical laboratories. It is useful for detecting and identifying certain forms of cancer and viral diseases, and holds promise for treating these diseases in the future.

A new type of degradable synthetic polymer was prepared by Rh-catalyzed three-component polymerization of a bis(diazocarbonyl) compound, bis(1,3-diketone), and tetrahydrofuran. The resulting polymer, poly(β-keto enol ether), was highly sensitive to mild acidic conditions and degraded into a combination of well-defined low molecular weight compounds. With this unique degradability, the polymer could be utilized as an environmentally friendly polymeric material.

A magma ocean existing during the core formation is thought to have been highly depleted in carbon due to its high-siderophile (iron loving) behavior. Thus, most of the carbon forming the atmosphere and life on Earth may have been delivered by a carbon-rich embryo after the core formation. However, a new high-pressure experiment has shown that previous studies may have overestimated the amount of carbon partitioning to the core.

Researchers from Duke-NUS Medical School, in collaboration with the Agency for Science, Technology and Research’s Bioinformatics Institute, and the University of Texas Medical Branch, USA, have discovered that the dengue virus changes its shape through mutations in Envelope protein to evade vaccines and therapeutics. The study also gives insights on the types of treatment strategies to use at different stages of infection. This could give rise to new approaches in vaccine development and treatment for dengue disease.

A group of biologists from Hong Kong Baptist University (HKBU) have discovered a new fireworm species in Hong Kong waters and named it Chloeia bimaculata. It is the fourth named species to be added to the fireworm genus Chloeia during the last century. The team also identified Chloeia parva as the fireworm species that caused the outbreak in Hong Kong last year. The discovery shows how little people know about the biodiversity of this group of animals.
