The newest release of images from New Horizons include this backlit view of Pluto, taken 15 minutes after the closest flyby. In addition to the geology, the image also interestingly reveals hazes in Pluto’s thin atmosphere. Read more about it here.
“The central moral objection to cloning-for-biomedical-research is that it involves the deliberate killing of human embryos. Much of the debate over cloning-for-biomedical-research therefore concerns the question of the moral status of the embryo. Is the embryo “one of us,” despite its apparent lack of distinctively human features and capacities? Do these youngest of human beings deserve our care and protection, or are there purposes that are sufficiently important to warrant killing them or using them in experiments?
We maintain that, because human embryos are human beings, they must “never be used as a mere means for the benefit of others.” Human embryos are members of the human species at the earliest stage of biological development. They are tiny in size and unfamiliar in appearance, but they are unmistakably individual human organisms—they do not become human at some later developmental stage. Occasionally scientists will aver that “science does not offer a hard-and-fast answer to the question of when human life begins.” The notion that it is impossible for science to answer the question of when human life begins, or even that the question is meaningless, can be convenient for scientists who want to use embryos as raw materials in their technological projects, but it also represents an abdication of the responsibility of science to provide us not only with technological power over nature but also with answers to questions about nature, including answers that might make us reconsider the moral implications of some of our growing technological power over nature.”
A new find of hominid fossils has been found in South Africa. The uniqueness of the find itself is undisputed. The find includes 15 partial skeletons, a big contrast to the usual fragmentary and isolated finds in paleoanthropology. What will take some more time to elucidate is the significance of the finding in the larger picture of hominid evolution. The discoverers have described the fossils as belonging to a new species, Homo naledi, while critics have disputed even the identification of the species, as well as its significance.
The more the phenomena of the universe are studied, the more distinct their connection appears, and the more simple their causes, the more magnificent their design, and the more wonderful the wisdom and power of their Author.
