The internet was amazed by images of the world's first warpship recently, and if you're wondering how science got past the fiction so quickly, remember how Leonardo is credited with inventing the helicopter? Despite not knowing any of the relevant aerodynamics, physics, engineering, or having any of the required skills other than "able to draw a pretty picture"? It's the same deal.

What could a criminal do with a speech synthesis system that could
masquerade as a human being? What happens if artificial intelligence
technology is used to mine personal information from smartphones?
AI is becoming the stuff of future scifi greats: A robot that can open doors and find electrical outlets to recharge itself. Computer viruses that no one can stop. Predator drones, which, though still controlled remotely by humans, come close to a machine that can kill autonomously.

Beyond genomics, biologists and engineers decode the next frontier
Evidence has mounted that global warming began in the last century and that humans are, at least in part, responsible. The concern is that the warming of our climate will greatly affect its habitability for many species, including humans. Both the Intergovernmental Panel on Climate Change (IPCC) and the U.S. National Academy of Sciences concur that this is the case. But some argue that this thinking is too limited. They say that too many scientists are either ignoring, or don’t understand, the well-established fact that Earth’s climate has changed rapidly in the past and could change rapidly in the future—in either direction.

A new study shows that cosmic radiation could be accelerating the
growth of our Earth forests, though - as with most cosmic radiation
effects - we don't know how it's happening or what the effects are.
But in accordance with standard "Science From Fantastical Space
Radiation" practice, the results were only discovered by accident.

2012 a disaster flick about the end of the world is currently assaulting movie goers across the country. The plot of the film, which grossed more than $65 million on its opening weekend, revolves around the ancient Mayan "prophecy" that we will all be obliterated on December 21, 2012, the date on which the Mayan calendar ends - a prophecy that was also referenced in the series finale of The X-Files as the launch date for the ultimate alien invasion.
Meanwhile, NASA has found itself answering so many common questions that their Ask an Astrobiologist video offers calming, professional reassurance that there is no planet Nibiru, nor will it collide with Earth.
Interstellar Highway Patrol take note: MIT astronomers announced that stars of a recently discovered type, tagged ultracool subdwarfs, take some pretty wild rides reaching speeds of one million mph as they orbit around the Milky Way, following paths very different from those of typical stars. One of them may actually be a visitor that originated in another galaxy.
In a unique experiment on a galactic scale, millions of bacterial spores were purposely exposed to space, to see how solar radiation affects them and the results supported the idea that not only could life have arrived on Earth on meteorites, but that considerable material has flowed between planets.
The disc and bulge of NGC 4710, surrounded by luminous eerie-looking dust lanes, are found in the constellation Coma Berenices, a region rich in galaxies, containing the northern part of the Virgo cluster. When staring directly at the center of the galaxy above, you can see a faint, ethereal "X"-shaped structure, which astronomers call a "boxy" or "peanut-shaped" bulge. The odd shape is due to the vertical motions of the stars in the galaxy's bar and is only evident when the galaxy is seen edge-on.

Our planetary surveys are nowhere near Star Trek's strike rate - they keep finding worlds stuffed with green-skinned females, humanoid societies, and thinly veiled metaphors for the situations they left behind a few hundred light (and regular) years ago. We find rocks which could freeze, explode and crush organic life just by looking at it. Now we've found a couple of Earth-sized oxygen atmosphered bodies, which would be all the way M-Class except for one thing: they're stars.
Specifically, they're "white dwarfs": old stars who've burned all their hydrogen fuel, gone through the red giant stages where they fuse their way up to heavier elements, but lack the mass to supernova and collapse into neutron stars or black holes. This is actually what'll happen to most stars, a relatively calm and cold fate, but there's no explosion so you don't hear about it much.

Bill Murray and Dan Aykroyd don't need to suit up for this one. NASA's
Chandra X-ray Observatory has found a cosmic "ghost," and scientists
think it is evidence of a huge eruption produced by a supermassive
black hole equal in power to a billion supernovas. The source, HDF 130,
is over 10 billion light years away and
existed at a time 3 billion years after the Big Bang, when galaxies and
black holes were forming at a high rate. The explosion of each super-massive black hole may, according to recent theories, collapse to form a number of new universes.

Ancient pines close to treeline have wider annual growth rings for the period from 1951 to 2000 than for the previous 3,700 years, reports a University of Arizona-led research team. Regional temperatures have increased, particularly at high elevations, during the same 50-year time period. Increasing temperatures at high altitudes are fueling the post-1950 growth spurt has been observed in Rocky Mountain bristlecone pines, including ones in Arizona's San Francisco Peaks.

The Medea Program has released secret spy pictures of a melting Arctic,
but don't worry: we're not under alien attack just yet. "The Medea
Program" might look like something you'd see written on a thick
paperback (possibly above an image of knives and spy satellites) but in
reality it's a program to share declassified intelligence agency
information with scientists. Who might actually do something with it.

NASA's most awesome mission since pointing at the sky and saying "I bet we can put people there" has come to fruition, with absolute proof that there's water ice on the Moon - and lots of it.
The Lunar Crater Observation and Sensing Satellite (LCROSS) is the most explosive euphemism since Tom Clancy discovered the thesaurus. It 'sensed' the contents of the lunar crater Cabeus by dropping an entire Centaur rocket booster into it, and when you 'drop' something in orbit it's very much like 'fired at' by the time it hits the ground. The booster slammed into the shadowed regolith like a two ton bullet, blowing a twenty meter hole in the moon and ejecting dust tens of kilometers into space - where the LCROSS satellite, chasing the Centaur, could get a good look at it for four minutes before its own suicide strike into the same crater.

Jupiter's been in the news a lot this past summer, as anywhere there's a Pacific-Ocean-sized explosion tends to be. The recent impact (and detonation)
of an asteroid against the gas giant's hide has triggered the usual
flurry of discussion with the planet cast as everything from cosmic
protector to vengeful heavenly killer (both believable aspects of
Jupiter, the god the Romans ripped off from the Greeks, but less so for
the actual solar system object). Both miss the real answer: it's just
there, and sometimes things just happen.

A Mars mission to be launched in October on a Russian robot spacecraft
will include specimens of thale cress; tiny water creature tardigrade -
or water bear - which can
also survive extraordinary extremes of temperature and pressure;
samples of brewer's yeast; and permafrost from the Siberian Arctic.
Together with several other microscopic organisms, these
representatives of Earth life will be carried in a package that will
be flown to Mars and are scheduled to be returned to Earth in 2012.

"The universe could so easily have remained lifeless and simple -just
physics and chemistry, just the scattered dust of the cosmic explosion
that gave birth to time and space. The fact that it did not -the fact
that life evolved out of literally nothing, some 10 billion years after
the universe evolved literally out of nothing -is a fact so staggering
that I would be mad to attempt words to do it justice. And even that is
not the end of the matter. Not only did evolution happen: it eventually
led to beings capable of comprehending the process by which they
comprehend it."

Philosophy is a vital study for the human
race - from the ancient Greeks to the modern day, some of the finest
thinkers have examined the human condition and produced valuable
insights and conclusions on what it means "to be." Unfortunately much
of the other work in the field is dubious, including a recent paper
which argues that we're all living in a vast computer simulation. Yes,
it WAS written after the first Matrix film but before the sequels.
Funny that.

The U.S. Department of Energy has already begun holding workshops on building a system that's 1,000 times more powerful as the Jaguar, capable of a peak performance of 2.3 petaflops. — an exascale system, said Buddy Bland, project director at the Oak Ridge Leadership Computing Facility that includes Jaguar. An exaflop is a million trillion calculations per second, (one quintillion) or 1,000 times faster than a petaflop.

Spiral galaxies NGC 5426 and NGC 5427 are passing dangerously close to each other, but each is likely to survive as the galaxies advance over the next tens of millions of years, their component stars are not likely to collide, although new stars will form in the bunching of gas caused by gravitational tides. Close inspection of the above image taken by the 8-meter Gemini-South Telescope in Chile shows a bridge of material momentarily connecting the two giants. Known collectively as Arp 271, the interacting pair spans about 130,000 light years and lies about 90 million light-years away toward the constellation of Virgo. The Milky Way Galaxy will undergo a similar collision with the neighboring Andromeda Galaxy in about five billion years.
