Well for those who care but are not into SACRIFICE check out the Lazy Environmentalist. I subscribe to his podcast. Other related podcasts I subscribe to are that are environmental related Earth & Sky, Living On Earth, Pulse of the Planet, and Science Friday. Avoid The Green Peril or you too could suffer the fate of South Park in Smug Alert!

Obviously the best out there for new music is The Indie Sermons of the Rt. Rev Fischer (RSS).

More seriously there are some from a non-geek perspective (it's good to get out a bit):

Dreadful Snake Radio (RSS
A middle aged former musician turned corporate guy. He mixes his love of folk/blues in with his world travels. It is a little "what I did today" but what he does daily is amazing. Everything from podcasting while doing a 5k with his son, while biking in Beijing, at the Telluride Bluegrass Festival, to Church (state sponsored) in Beijing on Christmas.

Rocket Boom
Just great. (actually a video cast)

Earth & Sky (RSS)
A great public radio science show. It is not always just new science, it is a lot of explanations that you have probably always been curious about. And it is the best way to stay up to date on cool science events (eclipses, meteor showers, that kind of thing)

Sun heats the land, air and water unevenly which makes wind (read more). Wind blows the water which makes waves (read more). Waves bend the joints between the floats, which causes fluid to be pumped, which turns generators, which makes electricity (read more).

So your thinking is correct -- there's no such thing as a free lunch. If the energy ever stops coming into this system (i.e., the sun stops shining), we've got big problems... :-)

Sort of. See e.g. this link. I think the idea is that it slows aging, but not enough to extend someone's life enough for say interstellar travel. For that we'll need a combination of hibernation and anti-aging mechanisms and anti-disease mechanisms, or some kind of hard stasis (for instance, imagine if you had some kind of nanobot that could separate each individual cell, place each in indefinite stasis, and then reconstruct the whole after a very extended period of time).

widespread adoption of the second-full-Moon-in-a-month definition followed its use on the popular radio program StarDate on January 31, 1980. We examined this show's script, authored by Deborah Byrd, and found that it contains a footnote not read on the air that cites Pruett's 1946 article as the source for the information. Byrd now writes for the radio program Earth & Sky, whose Web site contains a few short notes giving her perspective on this modern contribution to lunar folklore.

As with so many rare finds, the real question is How to not contaminate or destroy what we've found, while still getting access to the knowledge we want.

On the other hand, there is this article, about the Rio Tinto in Spain, which supports life despite a pH of around 2. It might not be totally separate or isolated, but that's a pretty alien environment. (another similar story, including a brief discussion of astrobiology, is here.

This was developed by Eric Mazur of Harvard University and his colleagues.

The MASER was the predecessor of the LASER. Though most don't know this, LASER is an acronym standing for "light amplification by stimulated emission of radiation." The difference is that MASERs amplify Microwaves instead of light.

Isn't it convenient that the lead scientist on this is named just happened to be named "Mazur?" . . . Waitaminut, where'd that black helicopter come from?

(You can get a little info about MASERs and LASERs here)

There used to be a large model in Austin - the guy used the dome of the Texas capitol to represent the Sun, and a basketball was used for Earth.
Brief mention here, although the scale they mention seems a bit off.

Or what about calling it Sphaero? Seems appropriate to me.

The resemblance between jellyfish and the Portugese man-o-war is mostly a matter of appearance, although there are some functional similarities too (both have stinging cells and drift freely, for instance).

Man-o-war are siphonophores, and the biologists say they are communal organisms. The transparent blue bladder that floats on the sea surface is one animal; each stinging tentacle that hangs from this float is another, each leech-like feeding polyp still another, and the community is further enlarged by separate male and female reproductive polyps. None of these animals can reproduce or even exist apart from the colony, but they have distinct separate genetic material.

The whole thing plays hell with traditional definitions of what individuality is, and what exactly comprises a single organism.

Depends on your time zone (Earth & Sky has a few details).
