When drops of water touch the surface of a lotus flower leaf, they form beads and roll off, collecting dust particles along the way. In contrast, water droplets on a rose petal also form beads, but remain pinned to the petal's surface. A mechanical engineer at Washington University in St. Louis combined the two concepts to find a more efficient way for droplets to evaporate from a surface. from Phys.org - latest science and technology news stories https://ift.tt/2F82ZBp

When a semiconducting nanowire is coupled to a superconductor, it can be tuned to topological quantum states thought to host localized quasiparticles known as Majorana Zero Modes (MZM). MZMs are their own antiparticles, with promising applications in topological quantum computing. Due to particle-antiparticle equivalence, MZMs exhibit quantized conductance at low temperatures. While many theoretical proposals exist to realize MZMs in solid state systems, their experimental realization is confronted by non-idealities. from Phys.org - latest science and technology news stories https://ift.tt/2MHpVeU

Due to the advantages such as large specific surface area, adjustable pore size and tunable functionality, metal-organic frameworks (MOFs) have shown great application potential in the fields of gas adsorption and separation, catalysis, sensing and biomedicine. However, most metal-organic frameworks have pore sizes below 2 nm and are typical microporous structures, which limits pore structure and hinders mass transfer within the framework. In order to overcome this limitation, researchers introduced mesopores or macropores in microporous MOFs to generate multi-level pore structure through various strategies. from Phys.org - latest science and technology news stories https://ift.tt/39pBwt0

Certain bacteria can override a defence mechanism of the immune system, so called programmed cell death, through inhibition of death effector molecules by their outer membranes components. Shigella bacteria, which cause diarrhoea, use lipopolysaccharides (LPS) on their surface to block the effector caspases. Lipopolysaccharides are a component of the bacterial outer membrane. This strategy enables the bacteria to multiply within the cell. This is the result of a study conducted by the molecular immunologist Professor Hamid Kashkar and his team in the institute for Medical Microbiology and Immunology at the CECAD Cluster of Excellence in Aging Research at the University of Cologne. The article, "Cytosolic Gram-negative bacteria prevent apoptosis by inhibition of effector caspases through LPS," by Günther et al., appeared in the current issue of Nature Microbiology. from Phys.org - latest science and technology news stories https://ift.tt/35WRJ6N
