Biotech companies have responded by noting that fatality levels in the field will not match laboratory levels and that use of Bt corn is far more preferable to using conventional chemical pesticides. Nonetheless, the monarch is seen as particularly vulnerable. It feeds exclusively on milkweed which frequently grows in association with cornfields. What is more, the larvae are feeding at the exact same time of year that corn sheds its pollen. Losey, J.E., L.S. Rayor, and M.E. Carter.
Transgenic pollen harms monarch larvae.
In a century that has witnessed man s triumph over countless diseases it is somewhat ironic that, as the century closes, the cure for the common cold remains elusive. Rhinovirus is the leading known cause of colds. It infects a cell by first attaching itself to a cell surface molecule, ICAM-1, that then provides a means of entry into a cell. The team has developed a decoy molecule, tremacamra, that has already successfully reduced infection in tests on chimpanzees and humans. In the human tests, a group of 177 subjects were isolated in a hotel for 8 days.
