Conflicting Views: Embryonic And Adult Stem Cell Research - SpaceDaily  Left:  Given how many children starve to death each year, so called moral concern for day-old embryos does leave one wondering.  Though there has been considerable biological and political debate over the use of embryonic stem cells (ESCs) vs. adult stem cells (ASCs) as therapies for tissue engineering and organ transplants, inherent benefits and drawbacks in both techniques compel them to coexist and complement each other. "On the one hand, it's been very difficult to grow sufficient numbers of ASCs to regenerate tissues or create replacement organs," explains Technical Insights Research Analyst Katherine Austin.
Giving Mars Back its Heartbeat. Great Terraforming Debate: Part I - SpaceDaily  Terraforming was once solely the province of science fiction. In the 1930s, Olaf Stapledon wrote of electrolyzing a global sea on Venus in order to prepare it for human habitation in "Last and First Men." Jack Williamson coined the term "terraforming" in the 1940s in a series of short stories. And in 1951, Arthur C. Clarke gave the concept wide exposure with his novel, "The Sands of Mars." Kim Stanley Robinson picked up the terraforming torch in the 1990s with his epic trilogy - "Red Mars, Green Mars, and Blue Mars." So the question is, can we terraform Mars? How would we do it, why would do it, when we do it, and should we do it? Chris McKay: I don't think we can terraform Mars, if terraforming is, as it was originally defined, making Mars suitable for human beings. But what we could do is make Mars suitable for life. 

The Red Planet Dead Or Alive? - SpaceDaily  Is there or has there ever been life on Mars? A UK project could help provide the answer to this fascinating question. The team are working to improve the equipment on space probes which is used to try and identify evidence of life on other planets. Current methods of detecting biomarkers are of limited effectiveness because they use biological receptors which can be fragile when facing the extreme environmental conditions involved in exploration work. This EPSRC-funded project sets out to demonstrate alternative approaches that offer greater flexibility for the detection of different biomarker molecules.
