Immunity can be lymph-less
Jef Akst | May 26, 2009 | 2 min read
Researchers have overturned the long-standing notion that lymph nodes are always necessary for launching the mammalian immune response. Fluorescently-labeled mouse liver Image: Burkhard Becher According to a linkurl:study;http://www.plosbiology.org/article/info%3Adoi%2F10.1371%2Fjournal.pbio.1000109 published in this month's issue of PLoS Biology, in the absence of lymph nodes, cell-mediated immunity can be activated in the liver. The findings undercut immunology "dogma," which says the immun

Laywell, UT MemphisMultipotent clones of cells derived from the adult human brain With the promises and challenges of stem cell research in the headlines, visions of artificial livers dance in the public's eye. Bioethicists, politicians, and citizens alike continue to debate whether public funds should be used to obtain cells from human embryos and fetuses. On the scientific front, however, the implications of stem cell research are even more profound than offering replacement parts.

Stem Cell Discoveries Stir Debate
Douglas Steinberg | Nov 12, 2000 | 9 min read
Editor's Note: This is the first of two articles on questions raised by recent stem cell discoveries. The second article, focusing on various organs and the nervous system, will appear in the Nov. 27 issue of The Scientist. Researchers first isolated embryonic stem cells (ESCs) from mouse blastocysts almost 20 years ago, and a paper announcing the discovery of human ESCs emerged in 1998. Adult-derived stem cells (ASCs) have since become the rage in certain quarters of biology, with unexpected--
