I just looked at the first 10 articles in Nature. Most declare no conflicts of interest. One author of one paper seems to have started a company based on similar technology: potentially a bias, but also potentially putting one's money where their mouth is. One other author lists some consulting work for a few companies. As for grants, I doubt people are bending their results to appease the NSF or NIH. There's certainly groupthink in what gets funded. We're still throwing money down the ABeta-for-Alzhemier's hole, for example. That eventually shapes what topics get published, but maybe not the specific results. The recent Abeta articles are pretty negative, for example.
