The lakshman rekha between science and business

Is science for betterment of humanity or for profits? No one has a better answer. When we see the breakthroughs in science over the past century, one feels that science has revolutionised the health and reduced mortality rate. Probably, 33% of present population are living due to timely intervention of science and health (for eg, vaccination, first aid etc). but, if we see the profits of the multinational pharmaceutical companies such as Pfizer, GSK, Astrazeneca, Monsanto etc, we feel that science is just a business.
The controversy over Bt brinjal is a good example where the MNCs are pushing their products over poor farmers. No one thinks whether the toxin towards pests is safe for humans or not. moreover, Bt cotton has increased burden on farmers rather than reducing them. the prices of seeds have increased enormously over the period when Bt cotton was introduced. Now, Monsanto claims that the old Bt cotton variety is vulnerable to pests and is planning to introduce new one. Imagine long terms effects if these are short term effects?
Latest article in science tells that a US judge rejects patent on breast cancer genes BRCA1 and BRCA2 by Myriad Genetics of Salt Lake City. The opposition groups claim that these genes are product of nature and thus can not be patented. Myriad, licensed the BRCA genes from the University of Utah and others who discovered them. In addition, it runs a testing service to check for mutations that convey a risk for breast cancer. Hope sense prevails on the scientists who discovered them and not become too capitalist.
