Tomorrow researchers, at the University of California, Los Angeles, will rally  for the second year in a row in support of biomedical research and against attacks and harassment by animal-rights extremists. From the "Pro-test" Web site:
... Animal rights extremists have continued to escalate their threats against researchers and their families.
On Thursday April 8th Pro-Test for Science will respond by rallying students, scientists and members of the public to support the cause of medical science. We call on the community to stand together against the recent tide of animal rights activism which has worked to misrepresent researchand coerce those that carry it out.
Last year's event  attracted hundreds of supporters, as well as a smaller counter-protest by animal-rights activists.
