really amazing

announcement of broadcast of documentation about Terraforming Mars on the 19th of November (with nice videos)

Please give the title of at least one Sci-fi novel in which terraforming was mentioned ;)

if you view the source code there's also an RSS feed

well, it seems we'll never be able to see the yes...!

so ooooooooooooold!!!!

Will it solve energy problems on Earth?

It turns out that falling along any straight line through the Earth takes 42 minutes (Gravity train). I think this has not been opted as an explanation of Douglas Adams' 42 but this fact is definitely quite beautiful.

A new mechanism was discovered on how H2 and N2 participate in the radiation budget. This may help to resolve the "faint young sun paradox", a hypothesis according to which during the earlier age of the solar system when sun radiation had lower intensity than now, the earth was warmer. Extended, it could reassess the past habitability of Mars.

Over the last 1000 years, temperature differences between the Northern and Southern Hemispheres were larger than previously thought. Using new data from the Southern Hemisphere, researchers have shown that climate model simulations overestimate the links between the climate variations across the Earth with implications for regional predictions.

"Over the past few months, the European Space Agency's Rosetta space probe closely examined the type of comet that some scientists theorized could have brought water to our planet 4 billion years ago. It found water, but the wrong kind."

Some bacteria can influence the weather. Up high in the sky where clouds form, water droplets condense and ice crystal grow around tiny particles. Typically these particles are dust, pollen, or even soot from a wildfire. But recently scientists have begun to realize that some of these little particles are alive - they are bacteria evolved to create ice or water droplets around themselves. old but might be worth a discussion

I still think, the lizards have evolved at an unexpectedly high rate and have now taken over the satellite...

Plastic may be with us a lot longer than we thought. In addition to clogging up landfills and becoming trapped in Arctic ice, some of it is turning into stone. Scientists say a new type of rock cobbled together from plastic, volcanic rock, beach sand, seashells, and corals has begun forming on the shores of Hawaii. The Anthropocene might just be on its way

Unlike any other living thing on Earth, electric bacteria use energy in its purest form - naked electricity in the shape of electrons harvested from rocks and metals. We already knew about two types, Shewanella and Geobacter. Now, biologists are showing that they can entice many more out of rocks and marine mud by tempting them with a bit of electrical juice. Experiments growing bacteria on battery electrodes demonstrate that these novel, mind-boggling forms of life are essentially eating and excreting electricity.

Last week NASA and NOAA announced that 2014 topped the list of hottest years ever recorded. Yikes! What's worse, the ten warmest years ever recorded have all occurred since 1998. Yikes again! In the meantime, the ACT is skiing on stones and rocks in Switzerland ^^

The UK-led Beagle 2 Mars lander, thought lost on the red planet since 2003, has been found partially deployed on the Martian surface. New images show that it successfully touched down on the planet's surface in 2003 but failed to deploy all four of its solar panels, thereby allowing no communication with scientists on Earth.
