Ice lithography: Opportunities and challenges in 3-D nanofabrication

Nanotechnology and nanoscience are enabled by nanofabrication. Electron-beam lithography (EBL), which makes patterns down to a few nanometers, is one of the fundamental pillars of nanofabrication. In the past decade, significant progress has been made in electron-beam-based nanofabrication, such as the emerging ice lithography (IL) technology, in which ice thin-films are used as resists and patterned by a focused electron-beam. The entire process of IL nanofabrication is sustainable and streamlined because spin coating and chemical developing steps commonly required for EBL resists are made needless.

Experiments with salt-tolerant bacteria in brine have implications for life on Mars

Salt-tolerant bacteria grown in brine were able to revive after the brine was put through a cycle of drying and rewetting. The research has implications for the possibility of life on Mars, as well as for the danger of contaminating Mars and other planetary bodies with terrestrial microbes. The research is presented at ASM Microbe 2019, the annual meeting of the American Society for Microbiology.

Major HIV drug requires vigilance, study says

A study lead by researchers at the Institute of HIV Research, Medical Faculty of UDE and University Hospital Essen reports a potential toxicity of integrase inhibitors. Integrase inhibitors (INSTI) are a preferred drug for inclusion in anti-retroviral therapy regimens given its tolerability, efficacy and high resistance barrier. INSTI have been found to improve and prolong lives of millions of people living with HIV who suffer side-effects and resistance to treatment. However, recent laboratory data suggest that INSTI may not be as safe as suggested.

Perovskite solar cells tested for real-world performance—in the lab

It was only ten years ago that metal-halide perovskites were discovered to be photovoltaic materials. Today, perovskite solar cells are almost as efficient as the best conventional silicon ones, and there is much hope that they will become a highly efficient and low-cost alternative, as they can be manufactured by rather simple and fast methods like printing.

Advanced computational modeling of the gut for biodefense

The Nutritional Immunology and Molecular Medicine Laboratory (NIMML) has developed a high-resolution model of the gut immune system by using advanced computational systems. The new high-performance computing (HPC)-driven model of the gut predicts new emerging behaviors and responses to biological threats. The gut ecosystem includes trillions of interactions between host epithelial and immune cells, molecules (cytokines, chemokines and metabolites) and microbes is a massively and dynamically interacting network, similar to a multidimensional jigsaw puzzle with pieces that are constantly changing shape. These interactions with cooperativity and feedback lead to nonlinear dynamics and unforeseen emergent behaviors across spatiotemporal scales. The NIMML model of the gut facilitates discovering new knowledge within this complex system for biodefense applications.
