Global catastrophic risks (GCRs) are risks of events that could significantly harm or even destroy civilization at the global scale. GCR raises a number of profound ethical issues, with a range of ethical theories suggesting that GCR reduction should be society’s top priority. This paper discusses GCR ethics in the context of dual-use bioengineering: bioengineering that can cause either benefit...

The development of the modern era of bioengineering and the advances in our understanding of the cardiovascular system have been intertwined over the past one-half century. This is true of bioengineering as an area for research in universities. Bioengineering is ultimately the beginning of a new engineering discipline, as well as a new discipline in the medical device industry.

Based on the information asymmetry theory and decision usefulness theory, combined with requirements of China market for enterprise research development disclosure, this paper analyzes current situation disclosure Hualan Bioengineering Co., Ltd., finds out problems existing in Bioengineering, puts forward corresponding countermeasures suggestions.

Multiplex genome editing is the simultaneous introduction of multiple distinct modifications to a given genome. Though in its infancy, maturation of this field will facilitate powerful new biomedical research approaches and will enable a host of far-reaching biological engineering applications, including new therapeutic modalities and industrial applications, as well as "genome writing" and de-...

Generating a defined set of genetic constructs within a large combinatorial space provides a powerful method for engineering novel biological functions. However, the process of assembling more than a few specific DNA sequences can be costly, time consuming and error prone. Even if a correct theoretical construction scheme is developed manually, it is likely to be suboptimal by any number of cos...

In recent years, we witnessed advances in biological science as well as nanotechnology which led to the design and construction of nano-scale useful devices to communicate with biological molecules and cells. Nanomachines are tiny devices at the scale of nanometer (10 -9 meters). These devices are still in the design and development phase. However, some nanosensors have been built and tested re...

they form juxtaposed pointillistic colour centres which, to our eyes, create the stimulus of the colour green (the same principle is used in many neo-impressionist paintings). One further special feature of this structurally coloured system, and possibly the reason it evolved, is that only the blue colour component is significantly linearly polarised; linear polarisation is sometimes used for i...

Despite the ubiquity of fluid flows interacting with porous and elastic materials, we lack a validated non-empirical macroscale method for characterizing the flow over and through a poroelastic medium. We propose a computational tool to describe such configurations by deriving and validating a continuum model for the poroelastic bed and its interface with the above free fluid. We show that, usi...

Arsenic is a natural environmental contaminant to which humans are routinely exposed and is strongly associated with human health problems, including cancer, cardiovascular and neurological diseases. To date, a number of biosensors for the detection of arsenic involving the coupling of biological engineering and electrochemical techniques has been developed. The properties of whole-cell bacteri...
