This isn't finished. But it will be. Two residential towers, dense with trees, will have their official opening later this year in downtown Milan, Italy, near the Porta Garibaldi railroad station. (The image is not a photograph, but an architect's rendering. The towers are built and the trees are going in right now.) I love this. I think these towers are gorgeous. Milan is a very polluted town; these trees will cleanse the air, pumping out oxygen and greening the cityscape.

MELISSA BLOCK, HOST:

We're accustomed to hearing about local weather conditions like high pressure zones or the jet stream. But just outside of the atmosphere, the conditions are a little stranger.

(SOUNDBITE OF ELECTROMAGNETIC WAVES)

BLOCK: That's a recording made by two new NASA satellites launched to study space weather.

As Lauren Sommer reports from member station KQED, the satellites could be in for some extreme conditions this year.

NASA's Kepler spacecraft has discovered three new "habitable zone" planets that are close to Earth's size, even if they're not all that close to Earth.

NPR's Joe Palca reports, the trio of worlds is about 1,200 light years away and are thought to lie in the so-called "Goldilocks zone" — where it's not too hot and not too cold for liquid water.

Kepler Telescope Spots 3 New Planets In The 'Goldilocks Zone'

The small squares superimposed on this image of the Milky Way galaxy show where in the sky the Kepler telescope is hunting for Earth-like planets. Kepler, which launched in 2009, has identified more than 100 planets.

Astronomers have found three planets orbiting far-off stars that are close to Earth-sized and in the "habitable zone": a distance from their suns that makes the planets' surfaces neither too hot nor too cold, but just right.

One of the three planets orbits a star with the prosaic name Kepler-69.

Bacteria On Dog Lovers' Skin Reveal Their Affection

Should we say Germ-an shepherd? Mango Doucleff, of Washington, shows off the bacteria living on her tongue, which also flourish on her owner's skin.

Well, it looks like there really is such as thing as a dog person.

Humans who share their homes with canines also share the similar bacterial houseguests on their skin, ecologists reported Tuesday in the journal eLIFE.

In fact, two dog owners who don't even know each other have about as many of the skin bacteria in common as a married couple living together.
