This beautiful little film really makes me want to visit Iceland.

SETI gets new funding … from Jodie Foster?
Actress Jodie Foster and writer Larry Niven are only two of the many people who helped raise enough money to turn the Allen antenna array back on. Okay space aliens, we’re listening for you!

The Waters of Mars … is real!
Mark this day down in your calendars. This is big news.
I was hoping NASA was going to say one of the rovers discovered a fossil or living space lichen … but running water on Mars, that’s pretty groovy too.
She blinded me with science…

This is a real creature…
Good thing you need an electron microscope to see its face.
When in Doubt, Blame Antigravity
Antigravity could replace dark energy as cause of Universe’s expansion
Since the late 20th century, astronomers have been aware of data that suggest the universe is not only expanding, but expanding at an accelerating rate. According to the currently accepted model, this accelerated expansion is due to dark energy, a mysterious repulsive force that makes up about 73% of the energy density of the universe. Now, a new study reveals an alternative theory: that the expansion of the universe is actually due to the relationship between matter and antimatter. According to this study, matter and antimatter gravitationally repel each other and create a kind of “antigravity” that could do away with the need for dark energy in the universe.
Twisting Space Time Messes with Subatomic Measurements … and my mind
“The spin of our Galaxy has a twisting effect on our local space that is a million times stronger than that caused by the spin of the Earth.” – from this article in Physorg.com
For those of you out there who are, like me, a sciencehead, this is kind of cool. Because I can close my eyes and imagine the mass of our entire galaxy spinning and, as a by-product, twisting and torturing the space and time around it. Of course my imagination then takes over and has this accounting for all sorts of anomalies that isn’t mentioned … or even hinted at … in the article. But I’ll save those for a science fiction story, because the reality of it is intriguing enough.
It goes on to say how, as the Universe was young and first forming, rotation and time/space twisting may account for other things we observe about reality here and now, including why there is apparently more matter than anti-matter in the Universe.
