Instead, Morishima suggests that the insects themselves could power the slave-driving chips. As a proof of concept, he glued a piezoelectric fibre - 4 centimetres in length but just 200 micrometres across - to the back of a Madagascar hissing cockroach. As the cockroach walked, each step stretched and squeezed the piezoelectric fibre, generating electricity via mechanical stress.
Next year is set to be one of the top-five warmest on record, British climate scientists said on Tuesday.
The average global temperature for 2009 is expected to be more than 0.4 degrees celsius above the long-term average, despite the continued cooling of huge areas of the Pacific Ocean, a phenomenon known as La Nina.
That would make it the warmest year since 2005, according to researchers at the Met Office, who say there is also a growing probability of record temperatures after next year.
If water ice is actually there, it should be stable for billions of years on the moon provided that it receives no sunlight.
"If the hydrogen is present as water ice then our results imply that the top meter of the moon holds about 200 billion litres of water," Teodoro added.
Contrary to Kahnneman and Tversky's research, Alex Pouget, associate professor of brain and cognitive sciences at the University of Rochester, has shown that people do indeed make optimal decisions -- but only when their unconscious brain makes the choice.
"A lot of the early work in this field was on conscious decision making, but most of the decisions you make aren't based on conscious reasoning," says Pouget. "You don't consciously decide to stop at a red light or steer around an obstacle in the road. Once we started looking at the decisions our brains make without our knowledge, we found that they almost always reach the right decision, given the information they had to work with."
TN has what is known as blind sight, according to de Gelder. Even though the primary part of his brain that processes visual information is destroyed, he still has more primitive parts of his brain intact, and these are capable of doing some visual processing. After all, one of the most basic functions of the visual system is to help an animal avoid obstacles or predators. TN still has some visual abilities -- he's just not aware he has them.
In the spring, a team will begin attempts to ignite a tiny man-made star inside a laboratory and trigger a thermonuclear reaction.
Its goal is to generate temperatures of more than 100 million degrees Celsius and pressures billions of times higher than those found anywhere else on earth, from a speck of fuel little bigger than a pinhead. If successful, the experiment will mark the first step towards building a practical nuclear fusion power station and a source of almost limitless energy.
We transhuman ufologists are a witheringly small bunch; although I've come across provocative discussions about nanotechnology and machine intelligence within the more intelligent corridors of ufology, committed transhumanists approach the subject of UFOs and the "paranormal" with pronounced disdain. The very definition of "skeptic," for instance, is summarily forgotten; among the more strident and vocal proponents of transhumanism, the very prospect of extraterrestrial visitation via UFO is considered naïve fantasy good for little more than placating true believers with elusive promises of galactic altruism. Certainly, they argue, we're better off parroting the so-called Fermi Paradox.
Assuming our species ultimately graduates to some enhanced level of existence, I think we'll probably take sex with us, if only as a souvenir. But our current version seems certain to fall by the wayside eventually; if we take the effort to improve our somatic operating systems, it's doubtful we'll continue running the same programs for the sake of simple nostalgia. Instead, we'll want something better, more meaningful, more in keeping with how we define ourselves as individuals and as a species -- if indeed we remain a single distinct species at all. In reality, the human future might be a bit like the scenario from contemporary space opera, splintered into factions that regard each other with more than a little sense of incomprehension.
As familiar as they've become, there's nothing overtly pleasant about them. Rather, they seem more than slightly ominous: jaundiced psychic postcards from the near-future landscapes of Philip K. Dick and J.G. Ballard. My very identity is relegated to that of a confused tourist; my itinerary, if there is one, seems limited to so much queasy sight-seeing. I can't plot a meaningful course of action, so I merely watch -- and awake with my mind's eye awash in fragments.
Perhaps I'm wary of any would-be neurological hackers. After all, a sufficiently capable technology (human or otherwise) might choose to exploit the gulf between "now" and the processed version accessed by our minds. (The rogue AIs of The Matrix certainly weren't above such devilish tricks.) Conversely, maybe we need that gulf -- maybe it's a kind of buffer that's evolved, in part, to keep us from drinking too deeply at the well of the Real (where literally unimaginable horrors might lurk, eager to hijack our sense of self and partake of the slippery phenomenon we call "consciousness").
Whoever they once were and wherever they're from, the Grays have suffered a cataclysmic schism between body and mind. Like the replicants of Blade Runner, they're largely immune to empathy and look to us with a mixture of fascination and sadness. They've lost something pivotal and will stop at nothing to get it back -- if, indeed, they remember what they've misplaced.
We boldly speculate about the potential of mind-uploading and the promise of designer bodies. We plunge forever deeper in to the resplendent weave of our own genome, shuffling molecules with Frankensteinian resolve. The Grays might be projections from our own future: imaginal constructs so heavily freighted with our own unresolved anxieties that they've become effectively palpable.
Not that SL is wholly without charm or promise. It possesses an agreeably anarchic flavor and its locales -- many flaunting ersatz cultures culled from fashion, history and science fiction novels -- betray an endearing alliance of geekdom. Endlessly fetishistic, venturing forth in SL is a bit like stumbling across a mall from the future of Blade Runner: an infestation of capitalistic frenzy so pronounced the billboards often ooze more personality than the inhabitants themselves. Much of SL's real-estate mirrors the progression of a lucid dream; upon returning to reality, you may find yourself waxing philosophical at inconvenient moments.
"You know, I have this sneaking suspicion you're not from another planet at all," I said as the coffee began percolating. "Maybe you’ve read some of my essays. I think you're real, but not necessarily the kind of 'real' we're used to. John Mack once used the term 'reified metaphor.' But a metaphor for what?"
I poured two mugs and offered one to the alien, who'd already started up Firefox and was busily scanning my RSS feeds. "Thanks," it said, wrapping a colorless finger around the handle. I sat on the living room's other chair, vaguely aware that my cats had begun congregating around the newcomer.
None of this is to suggest that UFOs are mere kitsch, ripe for the literary harvest. Extraterrestrial spacecraft or something else, I'm convinced that we're dealing with a very real phenomenon. However, I tend to think a true understanding will occur only when we take stock of our own neurological constraints; perhaps the devastating weirdness of the UFO spectacle needs our imagination in order to give voice to the inconceivable.
So, let's see: a very rich man wearing a gaudy dress at the head of an organisation which shelters and hence implicitly condones child abuse says that saving humanity from transsexual or homosexual behaviour is as important as saving the environment.
The Apple computer was invented in a garage. Same with the Google search engine. Now, tinkerers are working at home with the basic building blocks of life itself.
Using homemade lab equipment and the wealth of scientific knowledge available online, these hobbyists are trying to create new life forms through genetic engineering -- a field long dominated by Ph.D.s toiling in university and corporate laboratories.
I think Kurzweil's overly optimistic -- and naive in a sort of endearingly infectious way. Specifically, I don't think the post-biological future will arrive as abruptly as Kurzweil suspects. While I think many of his forecasts will indeed happen more or less as advertised, I foresee a more gradual -- and markedly less utopian -- transition. On the other hand, we might direly need the technologies Kurzweil describes in order to survive the excesses and hazards of the next century, and necessity is often the mother of invention.
Today the walls of Plato's cave are so full of projectors, disco balls, plasma screens and halogen spotlights that we do not even see the shadows on the wall anymore.
Scientists have previously reported cases of blindsight in people with partial damage to their visual lobes. The new report is the first to show it in a person whose visual lobes -- one in each hemisphere, under the skull at the back of the head -- were completely destroyed. The finding suggests that people with similar injuries may be able to recover some crude visual sense with practice.
I started out thinking that I'd been attacked in some way, but I'm not so sure now that my rape was really that, any more than surgery on a little dog at the veterinary clinic is assault. I surely felt assaulted, and so must the little dog. But the anger and fear could come, in both cases not from understanding of what happened, but from ignorance about it. The dog has no idea that the man who inflicted pain on him actually prolonged his life, and I wonder if those of us who have had rough experiences with the visitors are not in the same boat?
Here is some terrific video of a bioluminescent deep-sea siphonophore -- an eerily fantastic creature that appears to be a single, large organism, but which is actually a colony of numerous individual jellyfish-like animals that behave and function together as a single entity. The individual units, called zooids, all share the same genetic material and each perform a specialized role within the colony.
The frequency of extremely high clouds in Earth's tropics -- the type associated with severe storms and rainfall -- is increasing as a result of global warming, according to a study by scientists at NASA's Jet Propulsion Laboratory, Pasadena, Calif.
The wiring remains a hurdle: Dr Aziz says current technology, which requires surgery to connect a wire from a heart pacemaker into the brain, causes bleeding in some patients and is "intrusive and crude".
By 2015, he predicts, micro-computers in the brain with a range of applications could be self-powered and controlled by hand-held transmitters.
One of very many interesting points made by Jan Zalasiewicz in his new book The Earth After Us is that rising sea levels in an era of global climate change might actually -- ironically -- increase humanity's long-term chances of urban fossilization.
"If we and our children are very unlucky over the next few decades," he writes, "and the waters rise swiftly, then many of our cities may be as well preserved as Pompeii, as though in aspic."
What is that growing on my car dashboard? Is that a tree? Indeed, Ford and Honda's next-generation dashboard instrument clusters feature trees (a vine in Ford's case) that grow more lush as drivers maximize their fuel economy. Leaves grow like crabgrass in springtime if you use a light touch on the accelerator and go easy on the brakes.
University of Minnesota anthropology professor Kieran McNulty (along with colleague Karen Baab of Stony Brook University in New York) has made an important contribution toward solving one of the greatest paleoanthropological mysteries in recent history -- that fossilized skeletons resembling a mythical "hobbit" creature represent an entirely new species in humanity's evolutionary chain.
One of the leading activists to speak out against experiments that might involve inter-species breeding with humans and apes is Dr. Calum MacKellar, director of research at the Scottish Council on Human Bioethics, who this past April warned of a "controversial draft Human Fertilisation and Embryology Bill" which did not specifically place restrictions on human sperm being inseminated into animals. MacKellar argues "if a female chimpanzee was inseminated with human sperm the two species would be closely enough related that a hybrid could be born."
Indeed, there are many instances throughout the last century where experiments were planned which may have proven conclusively whether creation of a "humanzee" were possible, though according to public records, none were seen through to completion. However, does this mean that there couldn't have been other instances where interbreeding took place at other times?
Among other things, Christmas is a great time for being maudlin and suicidal. If your Christmas depression isn't sufficiently aggravated by rampant commercialism and insincere offers of Good Will Toward Men, there's always some miserable Christmas song playing in a public place to add a pang to your holidays. To facilitate your seasonal affective disorder, we have identified five of the most down-bringing.

One of the most revolutionary aspects of Roy's use of magnetohydrodynamics is that the vehicle will have no moving parts. The lack of traditional mechanical aircraft parts, such as propellers or jet engines, should provide tremendous reliability, Roy said. Such a design also will allow the WEAV to hover and take off vertically. Pretty amazing stuff.
"People learning about Milgram's work often wonder whether results would be any different today," said Burger, a professor at Santa Clara University. "Many point to the lessons of the Holocaust and argue that there is greater societal awareness of the dangers of blind obedience. But what I found is the same situational factors that affected obedience in Milgram's experiments still operate today."
It was generally thought that the sun's rays would be too weak on Mars to supply a significant amount of energy. However, the MIT team concludes that with a careful choice of location, solar energy can provide all the power a colony would need - even in the teeth of the Red Planet's infamous dust storms.
While the new report stops short of endorsing the Planetary Society's plan, it does urge a rethink of where and when to send astronauts. "The Obama administration and Congress should examine the Bush vision, assess its limitations . . . [and provide] clarification of the moon/Mars strategy with a timetable for the Mars component," it says.
"Even if it means somewhat easing the 2020 deadline for lunar return, NASA must ensure that the new architecture provides a solid foundation for the next generation of human spaceflight," it adds.
If you're thinking about booking flight on Virgin Galactic's SpaceShip Two, launching a payload with UP Aerospace or Armadillo Aerospace, or can't wait to watch the Rocket Racing League, you'll be happy to know New Mexico's Spaceport America is two steps closer to becoming a reality and not just a dream.
As scientists search for life on Mars, they should take a close look at rock varnish, according to a paper in the current issue of the "Journal of Geophysical Research."
The paper describes how a research team led by Kimberly R. Kuhlman, of the Tucson-based Planetary Science Institute, found bacteria associated with rock varnish in an area where the surrounding soils were essentially devoid of life. The study suggests that rock varnish could provide a niche habitat for microbial life on Mars and in other extraterrestrial environments devoid of liquid water.
Locals who phoned and e-mailed the Daily Comet and The Courier this weekend about the strange cloud formation did agree on one thing: "It was the weirdest thing I've ever seen," said Raceland resident Sandra Ledet, who shared some spectacular photos with the Daily Comet.
Shawn O'Neil, a meteorologist with the National Weather Service in Slidell, identified the phenomenon as a hole-punch cloud.
"They don't occur all that often, and they are usually caused when an aircraft intersects altocumulus or cirrocumulus clouds," he said.
On top of that, quantum non-locality could mean the mind is capable of being non-local to the brain, of floating to the ceiling of the room. It can become, as Stapp puts it, "unglued". His words "certain choices not specified by the physical dynamics" are world-changing. This idea would, if widely accepted, end the reign of scientific materialism, replacing it with a new dualism. It would mean the universe is not a "causally closed" system, locked down since the big bang, as mainstream science has always insisted it is, but open to freedom of choice by the autonomous, floating, matter-altering mind. We would have regained our souls.
Seeing an eddy up close produces a curious form of kinship, as if in the presence of something animate. It's somehow sacred and thrilling to have an eddy spin its fragile life away in your midst; the wind suddenly becomes an entity, distinct and defined, its machinations made visible like an organ saturated with dye and viewed on a medical scanner.
The greatest thing about this demo is its sheer practicality in the real world. So many have been talking about solar panel highways or body-heat generating mobile devices, but not so much about kinetic energy. The energy-generating springboard has the additional benefit of being comfortable on the feet and back, something cement and pavement clearly lack.
Delhi is a city choked in climate change. Mostly unregulated by urban planning, the city has colored the Yamuna river with an untold amount of sewage, darkened its skies with the particulate matter of thousands of commuters, and expanded its borders with illegal developments. Every monsoon season scrubs the skies clean, and recent developments, such as the conversion of public buses to CNG, have improved conditions, but 40% of its residents still live in virtual slums. Facing this landscape head-on is the festival 48 degrees Celsius, an exhibition of art at the intersection of urban planning, ecological rescue and aesthetic glory, which opened yesterday.
We've speculated that Europa experiences enough tidal flex from Jupiter to create possible energy sources for life. What Tyler is saying is that the moon may experience not just internal pressures but large waves pushing through the submerged ocean. These waves, of course, could be a way of distributing heat and dissipating tidal energies.
Sometime in 2007 I realized I was sick of hearing about "ufology."
The politics, the incessant clashes with an apathetic mainstream media, the endless discussion about inventing a research paradigm that actually works . . . not to say those aren't worthy subjects and noble goals, but they're not necessarily my goals.
To some, Strieber's online sensationalism negates his testimony as an "abductee." But in our rush to pigeonhole "Communion's" author as a metaphysical huckster (thus erasing the bothersome -- if tantalizing -- specter of the "visitors" in a single stroke), we miss out on a potentially rich understanding of how the UFO phenomenon interacts with us on an individual level.
Strieber himself has emphasized the emphatically personal nature of the contact experience, suggesting that its operative intelligence has chosen to bypass bureaucratic authority in favor of a deeper, more pervasive dialogue with our species. Even if Strieber is wrong about everything else, I suspect he's struck a vitally important vein -- with or without the assistance of the diminutive humanoids that populate his books.
If it's easy to underestimate the success that greeted "Communion" in 1987, it's even more difficult to appreciate its multiplex impact on our culture. The cover painting alone almost single-handedly defined the "alien" to many thousands of readers. Strieber even devotes a section of the book to a hologram-like mental image that allowed him to describe the cover's iconic alien to artist Ted Jacobs, offering the possibility that "they" were complicit in the portrait's creation. (Even if their abductions are clumsy, the visitors seem to be consummate self-promoters.)
I've always maintained that the content of a bona-fide SETI signal will dictate whether it's deemed fit for public dissemination. A series of prime numbers might be acceptable for relatively immediate disclosure, but what about plans for a super-weapon? Are we to accept that the SETI Institute (a privately funded enterprise) possesses the jurisdiction to divulge any and all potential ET transmissions with impunity?
And so we remain inoculated to the presence of the truly mysterious. The recent "Martian" found in a 2004 rover image has garnered surprisingly intense (if generally dismissive) attention from both independent bloggers and a condescending mainstream media. Meanwhile, the enigmas in Cydonia go conspicuously unremarked, dismissed as the stuff of wishful thinking or the stalwart dreams of conspiracy-mongers.
Recurring dreams of strange vehicles, inexplicably depopulated suburbs, labyrinthine interiors, forgotten monuments, amnesiac voyages between transitory cities, exquisite squalor, the bittersweet promise of decay.
I've sometimes found myself in the preposterous position of "defending" my desire to live, if not forever, then as long as scientifically possible.
So, why do I want to live forever?
Easy -- for the same reason that I want to wake up tomorrow. There's nothing especially disturbing about negligible senescence unless one approaches the idea with at least some degree of emotional bias. And to be fair, we've been forced to grow used to the seeming inevitability of death in much the same way that our ancestors were forced to accommodate plagues instigated by an inability to understand germs.
We scoff at Mr. Spock's clinical mind-set; passion, we argue, is vital to our humanity. But who said "humanity" is the standard upon which we must judge our future selves?
I want to keep gazing into the void even if doing so invites the void to gaze back. Indeed, provoking a rapport with the emptiness may prove to be part of our duty as a species.
More to the point, I wouldn't expect alien visitation to be readily understood as such. Like Carl Sagan, I expect contact to be lavishly strange (and can't refrain from noting that, in an interesting twist of logic, the UFO phenomenon has been dismissed by many Sagan disciples precisely because it's strange).
But if we're dealing with an extraterrestrial presence of the sort generally espoused by ufology's old guard, the fact that UFO behavior seems at least partly comprehensible veritably shouts at researchers to address the phenomenon anew. Hence my recent speculation about interstellar AI: certainly a more exotic prospect than "mere" aliens in fancy spaceships, and one more in keeping with contemporary technological futurism.
There's a tired quip that those interested in UFOs draw their enthusiasm from an unacknowledged need to experience the numinous without the antiquated baggage of conventional religion. To be sure, it would be amazing to learn that we're being visited by beings from elsewhere; then again, the Cosmos is certainly awe-inspiring enough without the need for interlopers, regardless how sophisticated.
And we're not necessarily blind to the brick wall bearing down on us; on the contrary, I think we see it all too well. The gestures and symbols are intended to be useless in precisely the same way that last month's cellphones are intended to be thrown out when the fake chrome starts to chip.
I'm especially troubled by the assumption that depression is necessarily a disease to be "treated" with barrages of pharmaceuticals. Is it conceivable that melancholy offers the experiencer a window on reality just as valid as those embraced by the mainstream?
I've never considered civilization anything more than a passing phase. It seems essential because it's all we know, but when we look at it squarely we find at least as many inherent flaws as benefits. I say it's time to venture out of the womb and look around.
Bostrom's argument is tantalizing and, on first glance, impressive. But it hinges on so many anthropocentric conceits that it reduces itself from a legitimate "either/or" to a merely interesting philosophical conjecture.
But none of this bothers me nearly so much as the fatalism at the core of Bostrom's thesis, which purports to reveal the role of intelligence in the universe but delivers little more than litany of uncertainties dressed in racy new clothes.
Could Gaia be sentient in some unrecognized sense? If so, how might it communicate (assuming it wanted to)? In David Brin's "Earth," Gaia achieves self-awareness via the electronic nervous system we call the Internet, but perhaps it doesn't need anything so fragile or human-friendly. A global consciousness might manifest in the planet's ambient EM field, in its chemicals, in the molecular architecture of its organisms.
Ultimately, do we really need a God to inject our existence with meaning? Even if humanity eventually discards the vengeful, anthropomorphic deities that haunt our religious texts, we might never give up asserting our desire to seek reassurance in the "divine," blinded by the rash, unspoken certainty that the Cosmos must yield to human conceptions of fairness and justice.
But the universe gives every indication of being truly unforgiving -- unless, of course, spacetime was "tuned" to allow life and sentience, a scenario that implies that our presence was, in some unknown fashion, anticipated. I personally lean to the distinctly less flattering notion that all outcomes are realized somewhere in the quantum abyss, rendering our existence (and that of hypothetical ETs) inevitable.
I know certain readers won't believe this, but I don't especially care what happened. To me, Roswell has never been a matter of "wanting to believe" that aliens are visiting us in fallible metal ships -- because when you really stop to consider it, the idea that we're presumably at the mercy of secretive creatures in fantastical craft comes burdened with its share of existential disquiet.
Certainly it would be nice to know we're not alone in the interstellar dark. But if Roswell was an extraterrestrial event, it leaves the ET motive murky at best. Perhaps, as argued by Stan Friedman, the aliens were busily monitoring our military installations at the dawn of the Cold War in order to assess any threat we might pose. Friedman's scenario is fundamentally peaceable; his alien visitors -- as opposed to the meddling Grays of Budd Hopkins and David Jacobs -- are likable enough, even if they're content to remain encapsulated in their iconic saucers instead of approaching us as openly.
The UFO phenomenon seems to deliberately engage us in a dialogue of images culled from memories both personal and collective. What's to prevent it from recasting alien invaders from a "B" movie if it furthers its attempts to communicate with us, if that is indeed its ultimate goal?
A panel of international scientists has suggested that the UN start preparing for a global defense against the threat of asteroids on collision courses with Earth. Though a large asteroid collision is extremely unlikely (the panel calculate a likelihood of two or three events every 1,000 years), the consequences of such an occurrence could be catastrophic, with potential to threaten all life on the planet.
Skeptics on the other hand, take on a heavy burden in giving themselves that name - it means they're imposing themselves as guardians or gatekeepers to science and the collective body of human knowledge. As such, when they fail to uphold fairness, and fail to understand something when criticising it, they deserve every bit of blowback that they get.
[Loop Quantum Cosmology] has been tantalising physicists since 2003 with the idea that our universe could conceivably have emerged from the collapse of a previous universe. Now the theory is poised to make predictions we can actually test. If they are verified, the big bang will give way to a big bounce and we will finally know the quantum structure of space-time. Instead of a universe that emerged from a point of infinite density, we will have one that recycles, possibly through an eternal series of expansions and contractions, with no beginning and no end.

Nevertheless, more than 16 billion pounds of coffee are produced globally every year, according to the U.S. Department of Agriculture. Misra estimates that the grounds from that haul could be used to make as much as 340 million gallons of biodiesel. For their part, the researchers turned grounds donated by Starbucks into biodiesel that had the added advantage of smelling like a fresh cup o' Joe.

The researchers compared attitudes to nanotechnology in 12 European countries and the US.
They then rated each country on a scale of what they called "religiosity" - a measure of how religious each country was.
They found that countries where religious belief was strong, such as Ireland and Italy, tended to be the least accepting of nanotechnology, whereas those where religion was less significant such as Belgium or the Netherlands were more accepting of the technology.
Now, building on a tradition of ground-based simulation that extends back to 1958, a new series of experiments, conducted by an interdisciplinary research team from the Faculty of Natural Sciences of the University of Aarhus, Denmark, suggests that indeed bacteria could survive beneath the martian soil.
Why am I such a spoilsport? Because life on Mars would make life on Earth a lot more complicated. First, imagine that there’s no life on Mars. That means we can go there, as we did on lunar missions, with no serious worries about bringing back deadly germs. (We initially quarantined Apollo astronauts upon their return to Earth. But by Apollo 15 NASA had concluded that the moon was as lifeless as, well, the moon.) No concerns about bringing deadly bacteria home, and none about contaminating the moon with earthly bacteria that might mess up its biospheric ecology.
Planetary engineering on the largest scale might one day reveal itself to us through the observation of a Dyson sphere or other vast object created by an advanced civilization. But it's interesting to think about alternative strategies for using celestial energies, strategies that assume vast powers at the disposal of mankind as projected into the distant future. Thus an interesting proposal from the Swiss theorists M. Taube and W. Seifritz, who consider what to do about the Sun's eventual evolution into a planet-swallowing red giant.
"What you're seeing is a piece of flat, platy, layered sulfur-rich outcrop rock like we've seen almost everywhere the Opportunity rover has been in Meridiani Planum," said Bell. "Sometimes, like in this case, those flat, platy rocks have been tilted or dislodged, this one probably from the forces associated with the huge impact crater that formed nearby."

Soot or black carbon darkens the ice and makes it soak up more heat, accelerating a melt compared to reflective snow and ice. Methane comes sources including oil and gas and agriculture while ozone is formed from industrial pollutants.
"Reductions in these pollutants would have a greater impact" in the next two decades than curbing emissions of the main greenhouse gas -- carbon dioxide -- according to scientists on the sidelines of 187-nation UN climate talks in Poland.
"The United States should be less concerned that terrorists will become biologists and far more concerned that biologists will become terrorists," the report states.

British UFO researcher Gary Heseltine, who edits a monthly UFO magazine in the UK, says that he has some of the debris that was collected by the soldiers, who saw the UFO slam into the Troodos mountain range in Cyprus in 1973. They were ordered to collect the debris and put it into black plastic bags, but Clarke managed to confiscate some small pieces of golden tinted foil (similar to the debris found at Roswell).

But its discovery in an area far from the galactic center in an area known as 'G31.41+0.31' suggests that the production of this key ingredient for life could be common throughout the galaxy. This is good news in our search for alien life, because a wide spread of the molecule improves the chances of its existing alongside other molecules vital to life, and in regions where Earth-like planets may exist.
The concept is applicable to freshwater or shoreline applications and consists of an outer ring membrane with an interlacing web of pedestrian roads connecting the hotel, cafes, a restaurant and garden areas. The Aerohotel would also include recreational activities on the water-line below and would be accessible via sea or built to accommodate airship docking.
A mile and a half (two and a half kilometers) underwater, a remote control submersible's camera has captured an eerie surprise: an alien-like, long-armed, and -- strangest of all -- "elbowed" Magnapinna squid.

Every serious scientist knows that we and other animals evolved from the same ancestors. The real question today is whether to put our DNA and theirs back together. Until now, that question has been raised in the form of human-animal hybrids made in labs for research. You can argue that these are somehow wrong because they're newfangled and artificial. But what can you say about Neanderthals? They were made by nature, not industry. In fact, we're the industrial villains who apparently wiped them out. They're as natural as we are.
Concentrations of carbon dioxide (CO2) and nitrous oxide (N2O) touched new highs after more steady rises in 2007, and methane had its largest annual increase in a decade, the World Meteorological Organisation said.
"The major greenhouse gases -- CO2, methane and N2O -- have all reached new highs in 2007. Two of them, CO2 and N20, are increasing steadily and there is no sign of levelling off of those two gases," WMO expert Geir Braathen told a news briefing.
It could be argued, of course, that a ring made out of planetary material, a habitat so vast that it completely encircles its star, is actually one of the smaller Dyson concepts. It was in 1960 that Freeman Dyson suggested how a civilization advanced to the point of such astro-engineering might use everything it found in its solar system to create a cloud of objects, a swarm that would make the most efficient use of its primary's light. And as you keep adding objects, you point to the ultimate outcome, a Dyson Sphere that completely envelopes the star from which it draws its energy.
The company, Element Four, has developed a machine that it hopes will become the first mainstream household appliance to have been invented since the microwave. Their creation, the WaterMill, uses the electricity of about three light bulbs to condense moisture from the air and purify it into clean drinking water.
Over the years, say, tens of thousands -- even millions -- of these machines are installed in a humid city like New York, Tokyo, or London, achieving imperceptibly slow local climate modification. The city goes into a drought, with very little rainfall as humidity disappears -- and it's all because of a certain line of products that have been installed, gradually, home by home, over the course of a decade.
As astronomers explore newly discovered planets and create computer simulations of virtual worlds, they are discovering that water, and life, might exist on all manner of weird worlds where conditions are very different from those on Earth. And that means there could be vastly more habitable planets out there than we thought possible. "It's like science fiction, only better," says Raymond Pierrehumbert, a climate scientist at the University of Chicago, who studies planets inside and outside of our solar system.

Yet despite these shortcomings, Dick embodies everything that I like about sci-fi, for while his characters and their interactions may be lacking, the worlds in which they dwell and the societies that run them are superbly realized. The conflicts which arise in these worlds are fantastic, oftentimes absurd, and yet they mesh flawlessly with the reality that he created. It was these aspects that defined the genre for Dick and, in turn, it was these aspects that he poured most of his efforts.
Another classic case of the headline saying it all: physicists have confirmed that matter is no more than fluctuations in the quantum vacuum. Everything is arguably illusory, including ourselves. All of a sudden I have a vision of Terence McKenna muttering Beatles lyrics to the hyperspace elves in between fits of gently manic laughter . . .
To produce the clone, researchers took a cell from the ear of a dead Amami rabbit and injected it into the unfertilized egg of an ordinary lab rabbit. After the egg developed into the cloned embryo, researchers inserted it into the oviduct of a lab rabbit surrogate. The clone will be born in the coming weeks if the pregnancy comes to term.
