"Energy, food and water crises, climate disruption, declining fisheries, ocean acidification, emerging diseases and increasing antibiotic resistance are examples of serious, intertwined global-scale challenges spawned by the accelerating scale of human activity," say the researchers, who come from Australia, Sweden, the United States, India, Greece and The Netherlands.
Moveable flaps on sections of the lifting surface provide yaw control to allow the UAV to turn left or right. And flaps on the outside of the craft use the lift airflow to provide directional control, causing the craft to tilt and move in the direction of the tilt.
AESIR say their designs have inherent stability as a surveillance platform, thanks to a sustained hover capability, and can survive low speed impact with the ground, buildings and other fixed objects. They also have a large payload capacity when compared to similar sized fixed wing craft and have been designed to be flexible using "plug-and-play" payloads.
Then I have it - his 750ft-long merchant vessel is standing absurdly high in the water. The low waves don't even bother the lowest mark on its Plimsoll line. It's the same with all the ships parked here, and there are a lot of them. Close to 500. An armada of freighters with no cargo, no crew, and without a destination between them.
Reading a book by Franz Kafka -- or watching a film by director David Lynch -- could make you smarter.
Did you know that melanin, the pigment in hair, is light sensitive and can be used as a conductor? Well, that's what an 18 year old in Nepal recently discovered, and is now using human hair to replace silicon in solar panels.

I've seen "feral" used to describe dogs, cats, even goats. But I have wondered if it couldn't also be used to describe certain houses in Detroit. Abandoned houses are really no big deal here. Some estimate that there are as many as 10,000 abandoned structures at any given time, and that seems conservative. But for a few beautiful months during the summer, some of these houses become "feral" in every sense: they disappear behind ivy or the untended shrubs and trees planted generations ago to decorate their yards. The wood that framed the rooms gets crushed by trees rooted still in the earth. The burnt lime, sand, gravel, and plaster slowly erode into dust, encouraged by ivy spreading tentacles in its endless search for more sunlight.
The end of the fossil-fuel era, the fragility of the global food web, growing population density, and the spread of pandemics, as well as the emergence of radically transformative bio- and nanotechnologies -- each of these threatens us with broad disruption or even devastation. And as good as our brains have become at planning ahead, we're still biased toward looking for near-term, simple threats. Subtle, long-term risks, particularly those involving complex, global processes, remain devilishly hard for us to manage.
But here's an optimistic scenario for you: if the next several decades are as bad as some of us fear they could be, we can respond, and survive, the way our species has done time and again: by getting smarter. But this time, we don't have to rely solely on natural evolutionary processes to boost our intelligence. We can do it ourselves.
The problem is that a planet that close should be consumed by its parent star in less than a million years, say the authors at Keele University in Britain. The star Wasp-18 is believed to be about a billion years old, and because stars and the planets around them are thought to form at the same time, Wasp-18b should have been reduced to cinders ages ago.
"This planet should spiral inwards on such a short time scale that the likelihood of seeing it is very low," said Coel Hellier, an astrophysicist at Keele.
"That's a paradox," said Douglas P. Hamilton, an astronomer at the University of Maryland who wrote a commentary accompanying the report. He said there were a variety of possible explanations, none of them very satisfactory.
"Le petit prince" (the little prince) is a miniature greenhouse (concept) intended to walk a plant around Mars' surface in search of optimal growing conditions -- elements from light to nutrients. Eventually the robot masters its environment, sharing growing tips with a whole swarm of bots plant-growing robots.
But the prince is not just a growing machine -- the designer and 2009 Electrolux Design Lab finalist considers the bot first and foremost as a "pet" or "silent friend" to keep a colonist company.
Just because we have been taught to assign UFO phenomena to aliens coming from other planets does not make it so. (Actually, it might, but that's another ontological can of worms.)
We are stuck in a culture that needs to settle on one way to look at things, and uncomfortable with ambiguity, for the most part. Any non-human intelligence who wanted to "conquer" us, or at least make limited contact would do well to exploit this tendency, as well as our reliance on conscious sensory input to make their presence as subtle as a light breeze on our collective consciousness. No flying saucers, death rays, or even handshakes with the President needed.
Just recently the RRR Group posted a picture that my wife took at the MUFON Symposium in Denver and claimed that those of us on the Speakers panel were a bunch of geezers who had failed to solve the UFO question. It was time for us to get out of the way and let those younger, brighter and more enlightened take over. We had our chance and we failed.
Except we haven't failed. We solved the problem. We have the proof that some UFOs are alien spacecraft and we can make that point over and over. The evidence for that is overwhelming, but not unlike Galileo, who failed to convince the church that there were moons orbiting Jupiter, we get a bunch of people who "refuse to look through the telescope."
Breaking heat records in water is more ominous as a sign of global warming than breaking temperature marks on land, because water takes longer to heat up and does not cool off as easily as land.
"This warm water we're seeing doesn't just disappear next year; it'll be around for a long time," said climate scientist Andrew Weaver of the University of Victoria in British Columbia. It takes five times more energy to warm water than land.
The warmer water "affects weather on the land," Weaver said. "This is another yet really important indicator of the change that's occurring."
Scientists have long theorized that climate change could cause a negligible amount of movement in the axis, but NASA;s research shows that the problem could be much more severe than was initially thought. In fact, it could be as drastic as the northern pole shifting by 1.5 centimeters every year towards Hawaii and Alaska.
The British Ministry of Defense released 4,000 pages of documents detailing hundreds of UFO sightings between 1981 and 1996. A summary of the documents by UFO expert David Clarke comes as no surprise to scientists and skeptics: many of the sightings coincide with the release of popular sci-fi movies or television shows.
Now, a real-life a group of ambitious designers has taken their looming pyramidal arcology and placed it smack dab on the Mississippi River as a proposal for the rebuild of New Orleans which is currently in progress. This 30 million square foot beast-building with an array of green features is aptly named NOAH (Get it? Noah and the Arcology?), and is meant to house 40,000 mostly human residents.
