If you're a techno-addict and always have your laptop, smart phone or iPod attached to you, then these podcasts, e-newsletters and smart phone apps are a must.  

For those new to this (although I doubt those in the blogosphere are not 'in the know'), podcasts are like radio shows available for download to listen to as MP3 files (many are free, some are for-fee at places like iTunes); e-newsletters are the electronic form of paper newsletters - from companies, organizations, non-profits, magazines, etc (there are many popular e-newsletters including GOOP and Tree Hugger which are not mentioned here); and smart phone apps are the applications for Android-based smart phones or iPhones.

 Please add any of your favorites to the comments section, as my list is mainly science-based!
