Vultures detect carrion using smell, so you need knowledge of wind patterns where they are circling to determine carrion location. This has been suggested for use in the US when searching for a missing person, who might still be alive. While it sounds feasible, there is an associated cost in resources, which are usually limited, unless ornithologists and meteorologists are readily available and have access to local data about wind conditions. Wind conditions close to the ground, say up to 1000 feet can be variable: you can't just look at which direction the clouds are moving. Then you need to triangulate vulture locations, probably by ground observers at two or three locations trained to use compasses and maps. (The fire observers in fire watch towers do this type of location work for fires, or used to, for the US Forest Service.)

I'm surprised at how little mention has been made of the internet. You can raise funds for research, study any subject no matter what your age or language, access more books from more places, collaborate widely, promote any idea or concept, buy and sell practically anything. I'm 70 and listen to some 50 podcasts each week that deal with research, economics, culture, computers, medicine, politics, a foreign language, entertainment and world affairs; have to use fast playback speeds to get thru so much material. Much of it really good stuff, too. Is there any way to look at the impact this has?

It would be useful in mapping crime scenes. What happens, though, if you are outdoors; say a traffic accident with lots of vehicles?

Tons of information, much of it also restricted but still useful, by searching for the key agent, and for migrastatin.

Do a search for "institute for regenerative medicine" and see how many of these now exist.

Are folks playing Farmville doing what we are right here, reading and posting these remarks? Has anyone benefited from this discussion other than the social interaction?

This sort of device would probably work well with solar farms that presently concentrate sunlight onto a boiler.

I listen to the following podcasts that cover technical subjects and are the best I've found. The Naked Scientists provide the best overall coverage in hour-long sessions. Leoville's Futures in Biotech is very good in this cutting-edge field, but offers a limited number of entries. Perhaps more donations would enable the producer to do more. Microbeworld offers one-minute bites. Some of the leoville material that covers his radio call-in program last 2 hrs. Except for the FIB, all of his stuff is electronics-related (computers--Mac and Windows --, computer security, cell phones, digital cameras, and home theater). Some casts involve panels and guests. I've not included several more he does relating to food and children. Time compression software or other enhanced playback options are helpful with it as well as the other items if your time is limited.The Lancet offers several categories of current medical info. Podnuts is a computer repair discussion. Ziepod on Vista Home Premium works well to download all new episodes once a week. http://leoville.tv/podcasts/twit.xml http://feeds.feedburner.com/microbeworld http://www.theworld.org/rss/tech.xml http://leoville.tv/podcasts/kfi.xml http://leoville.tv/podcasts/fib.xml http://www.thenakedscientists.com/naked_scientists_podcast.xml http://www.cbc.ca/podcasting/includes/quirksaio.xml http://downloads.bbc.co.uk/podcasts/worldservice/docarchive/rss.xml http://leoville.tv/podcasts/leo.xml http://podcast.thelancet.com/laneur.xml http://podcast.thelancet.com/lancet.xml http://podcast.thelancet.com/laninf.xml http://feeds.feedburner.com/podnutz http://downloads.bbc.co.uk/podcasts/worldservice/mh/rss.xml
