The End of Chimpanzee Research.

In June 2010, Rosie, a descendant of the chimpanzees sent into space, and thirteen others were shipped from New Mexico to a laboratory in Texas for possible use in hepatitis research. They were to be the first group of approximately two hundred chimpanzees to be reintroduced to invasive research. These chimpanzees had been in semiretirement for a decade after being removed from an enormous laboratory that was in egregious violation of the Animal Welfare Act. I, along with many bioethicists, scientists, primatologists, and others, have long been arguing against the use of chimpanzees in invasive research on ethical grounds. The United States is now poised to join the rest of the world in ending invasive research on our closest primate relatives.

Ethical issues in African great ape field studies.

Great apes have been systematically studied in the wild for over half a century. Great apes are now critically endangered and this raises significant ethical issues for field primatologists who study and work to conserve these primates and their habitats. The most immediate ethical concerns involve the well-being of the subjects, but there are also important ethical considerations involved in researchers' interactions with local human populations and extracting industry representatives. This essay will discuss some of the ethical issues raised by African great ape research, with the hope of generating greater dialogue about best practices. After briefly presenting the history of great ape fieldwork, the ethical issues associated with habituation, intervention, and conservation will be discussed. This text will end with specific proposals that focus on the ethical concerns in great ape field studies.

Concise review: scientific and ethical roadblocks to human embryonic stem cell therapy.

Despite the identified therapeutic potential of embryonic stem cells for treating human disease and injury, a number of roadblocks, scientific and ethical, stand in the way of progress toward this goal. We identify six areas of particular interest: tumorigenicity, animal product contamination, genetic compatibility, funding, cell type for transplantation, "embryo-friendly" derivation methods and discuss avenues for moving beyond the difficulties.

Animal welfare and individual characteristics: a conversation against speciesism.

It seems impossible for a human being not to have some point of view concerning nonhuman animal (hereafter animal) welfare. Many people make decisions about how humans are permitted to treat animals using speciesist criteria, basing their decisions on an individual's species membership rather than on that animal's individual characteristics. Although speciesism provides a convenient way for making difficult decisions about who should be used in different types of research, we argue that such decisions should rely on an analysis of individual characteristics and should not be based merely on species membership. We do not argue that the concept of species is never useful or important. To make our points, we present a conversation among a skeptic, an agnostic, and a proponent of the view that our moral obligations to an animal must be based on an analysis of that individual's characteristics. In the course of the discussion, concepts such as personhood, consciousness, cognitive ability, harm, and pain are presented, because one's understanding of these concepts informs his or her ethical decisions about the use of animals by humans.
