Rescue fusion hybridization is a process used to manufacture some therapeutic cancer vaccines in which individual tumor cells obtained through biopsy are fused with an antibody-secreting cell to form a heterohybridoma . This cell then secretes the unique idiotype, or immunoglobulin antigen characteristic of the individ...

The REsearch Consortium On Nearby Stars ( RECONS ) is an international group of astronomers founded in 1994 to investigate the stars nearest to the Solar System - with a focus on those within 10 parsecs (32.6 light years ), but as of 2012 the horizon was stretched to 25 parsecs. In part the project hopes a more accurat...

The Research Defence Society was a British scientific society and lobby group founded by Stephen Paget in 1908 to fight against the anti-vivisectionist "enemies of reason" at the beginning of the 20th century. At the end of 2008, after being active for 100 years, it merged with the communications group Coalition for Me...
