3D Bioprinting for Tissue and Organ Fabrication

Abstract: The field of regenerative medicine has progressed tremendously over the past few decades in its ability to fabricate functional tissue substitutes. Conventional approaches based on scaffolding and microengineering are limited in their capacity of producing tissue constructs with precise biomimetic properties. Three-dimensional (3D) bioprinting technology, on the other hand, promises to bridge the divergence between artificially engineered tissue constructs and native tissues. In a sense, 3D bioprinting offers unprecedented versatility to co-deliver cells and biomaterials with precise control over their compositions, spatial distributions, and architectural accuracy, therefore achieving detailed or even personalized recapitulation of the fine shape, structure, and architecture of target tissues and organs. Here we briefly describe recent progresses of 3D bioprinting technology and associated bioinks suitable for the printing process. We then focus on the applications of this technology in fabrication of biomimetic constructs of several representative tissues and organs, including blood vessel, heart, liver, and cartilage. We finally conclude with future challenges in 3D bioprinting as well as potential solutions for further development.

'I Just Couldn't Fit It In': Gender and Unequal Outcomes in Academic Careers.

Abstract: This article reports on the findings of two pieces of research that were designed to test and challenge widely accepted theories about the causes of gender inequity in academic employment at the national level, and subsequently in a more detailed case study of one of Australia's largest and most prestigious universities. Both research projects used large-scale surveys to capture information about levels of human capital, family responsibilities, career preferences, workloads and objective experiences of appointment and promotion. The case study, conducted in 2002, also utilized focus group discussions with particular groups of women who seemed, from the survey data, to be located just under the glass ceiling. The case study research confirmed the earlier national survey research which concluded that discrimination or bias in appointments, promotions and workloads were not significant in explaining men's domination of the senior levels. It also confirmed the significant gender differences in some kinds of human capital (particularly possession of a Ph.D.). But it also pointed to a quite particular explanation for the failure of women to progress to Level D (associate professor/reader) which involved other more general demographic changes — particularly, high rates of separation and divorce, far higher rates of partnering among men than women and the impact of older children's needs.

The International Pulsar Timing Array: First Data Release

Abstract: The highly stable spin of neutron stars can be exploited for a variety of (astro)physical investigations. In particular, arrays of pulsars with rotational periods of the order of milliseconds can be used to detect correlated signals such as those caused by gravitational waves. Three such 'pulsar timing arrays' (PTAs) have been set up around the world over the past decades and collectively form the 'International' PTA (IPTA). In this paper, we describe the first joint analysis of the data from the three regional PTAs, i.e. of the first IPTA data set. We describe the available PTA data, the approach presently followed for its combination and suggest improvements for future PTA research. Particular attention is paid to subtle details (such as underestimation of measurement uncertainty and long-period noise) that have often been ignored but which become important in this unprecedentedly large and inhomogeneous data set. We identify and describe in detail several factors that complicate IPTA research and provide recommendations for future pulsar timing efforts. The first IPTA data release presented here (and available on-line) is used to demonstrate the IPTA's potential of improving upon gravitational-wave limits
