"ScienceDaily News" & Other Similar Physics Sources I'm retired and a little out of touch - no technical library. I subscribe to the free emails from ScienceDaily News on Quantum Physics News. It's an excellent source with links to advanced research especially in areas of photon entanglement, nano technology, etc. http://www.sciencedaily.com/news/matter_energy/quantum_physics/ I was not aware of ScienceDaily News until recently. What are some of the other similar science news email subscriptions? Know of any comprehensive list of free scientific research sources? On another subject, biomechanics and medicine, the National Center for Biotechnology Information (NCBI) has many free full publications available. (PMC = free full publications) http://www.ncbi.nlm.nih.gov/pmc/?term=tennis Are there similar sources for physics publications? Any links for general discussions of the current publication landscape for physics?
