Amniotic fluid (AF) and amniotic membrane (AM) have been recently characterized as promising sources of stem or progenitor cells. Both not only contain subpopulations with stem cell characteristics resembling to adult stem cells, such as mesenchymal stem cells, but also exhibit some embryonic stem cell properties like (i) expression of pluripotency markers, (ii) high expansion in vitro, or (iii...

Looking back over my career, I ... am hopeful, based on the progress achieved so far, that molecular sieve films will become a widespread energy-efficient separation technology. I am waiting for the day when someone will discover ... the “aeik nhton” (perpetual motion machine). The biggest challenge facing scientists is ... to ensure the peaceful use of their discoveries. My first experiment wa...

One of the most important factors affecting the future of mankind is the progress at technology. In my paper I shall ask how far human values are endangered by technological development and, conversely, how far certain restrictions placed on technology by these human values can be justified. It seems to me, however, that to specify such values and to legitimise certain restrictions on technolog...

n the United States and worldwide, the use of “complementary” and “alternative” and medicine is increasing, and has resulted in major non-reimbursed medical or health-related consumer expenditures. Although the term “complementary and alternative medicine” (“CAM”) has been largely adopted by the American academic community, there are also several possible other terms, such as alternative medici...

Each time diffusion of elements is invoked in explaining abundance anomalies in a star, this supposes implicitly that a stratification process is in progress somewhere in that star. This means also, that the element abundances can still be evolving according to the star’s age and fundamental parameters. Moreover, it has been shown that the superficial abundances may have complex temporal behavi...

For the past 20 years, democratization of additive manufacturing (AM) technologies has made many us dream of: low cost, waste-free, and on-demand production functional parts; fully customized tools; designs limited by imagination only, etc. As every patient is unique, potential AM for medical field thought to be considerable: would allow division dedicated patient-specific healthcare solutions ...

My question, which is central to the business of moral philosophy, is implicitly addressed by many philosophers, yet explicitly addressed by only a few. In this paper I address the question head-on, and propose a qualified affirmative answer. First, however, it is important to be clear about what is meant by 'morality' and 'progress', and what the meaning of 'is' is. My characterizations will n...
