Hi, The link below is a Google Sponsored Customized search engine for Life sciences related research. It is focused and very effective for all those working in Life Sciences, and related activities. The engine only searches your queries in about six thousand life science sites, and thus guarantees you more meaningful search result. The search results can be further refined based on 16 filters. The filters work for context of search (e.g drug design, clinical trial, laboratory informatics, regulatory affairs etc. ). There are other filters which filter the content ( looks exclusively for Pdf files, or Word files, or PowerPoint files). There are still more filters to look for Blogs, Pod-casts and Web-casts and webinars etc, Above all it is from Google and it is free!!
