BUT. So far, scientists thought that only stem cells from embryos could be used in this new frontier of research on man-made cellular regeneration. The ethical implications were obvious, some ethicists showed concerns, and abortion opponents declared stem cell technology immoral and wanted it banned. On the other hand powerful patients' groups were demanding the research.
THE (most recent) GOOD
NEWS IS that Science is progressing so rapidly in this new area
of research that it might circumvent the ethical dilemma.
In January 1999 researchers have announced that adult mice harbor certain ``mature stem cells'' designed to replenish one tissue that can sometimes be recoded to grow other tissues. If humans have the same capacity, stem cells from embryos might not be needed. We could after all take some of our own stem-like cells and convince them to grow into our most beloved tissue. We would be growing our very own cell garden.

Connected the first two modules of the International Space Station
The International Space Station (ISS) is one of those headlines which will be around for a good while. And will certainly make history. The first seed has been planted by coupling one Russian module (Zarya) and one American module (Unity) that orbit right now the Earth at 28000 Km/h, 400Km above our heads. It is just the beginning of a long process that should culminate in the year 2005. But the opening of the first room of this 'station with no definitive name' was certainly a celebrated event.
Not everything is to celebrate though. The critical economic situation of Russia has been a continuous burden and has caused repeated delays. Some critical voices even proposed the cancellation of the project or the dropping of Russian contributions. Nevertheless the Russian experience in space has proven to be most valuable and the own strategic and corporate interests from the USA have finally prevailed in going ahead with this expensive but profitable enterprise.
Once completed, the ISS will be the base campground for a wealth of new scientific experiments and discoveries which will boost our knowledge and achievements in materials science, biology, medicine and engineering, to name a few.
On the other hand, this is not the first orbiting space station. The Russians Salyut 1 and Mir are important precedents. So, what is so special about it?. Well, this is the first one involving from the beginning a cooperation between the USA, Russia, Europe, Canada and Japan. It is a global project.
