IF civilisation is wiped out on Earth, salvation may come from space. Plans are being drawn up for a “Doomsday ark” on the moon containing the essentials of life and civilisation, to be activated in the event of earth being devastated by a giant asteroid or nuclear war.
Construction of a lunar information bank, discussed at a conference in Strasbourg last month, would provide survivors on Earth with a remote-access toolkit to rebuild the human race.
A basic version of the ark would contain hard discs holding information such as DNA sequences and instructions for metal smelting or planting crops. It would be buried in a vault just under the lunar surface and transmitters would send the data to heavily protected receivers on earth. If no receivers survived, the ark would continue transmitting the information until new ones could be built.
The vault could later be extended to include natural material including microbes, animal embryos and plant seeds and even cultural relics such as surplus items from museum stores.
As a first step to discovering whether living organisms could survive, European Space Agency scientists are hoping to experiment with growing tulips on the moon within the next decade.
According to Bernard Foing, chief scientist at the agency’s research department, the first flowers - tulips or arabidopsis, a plant widely used in research - could be grown in 2012 or 2015.
“Eventually, it will be necessary to have a kind of Noah’s ark there, a diversity of species from the biosphere,” said Foing.
Tulips are ideal because they can be frozen, transported long distances and grown with little nourishment. Combined with algae, an enclosed artificial atmosphere and chemically enhanced lunar soil, they could form the basis of an ecosystem.

LONDON (Reuters) - Killer robots could become the weapon of choice for militants, a British expert said on Wednesday.
Noel Sharkey, professor of artificial intelligence and robotics at the University of Sheffield said he believed falling costs would soon make robots a realistic option for extremist groups.
Many of you have recently read that a research team at the University of Illinois led by Min-Feng Yu has developed a process to grow nanowires of unlimited length. The same process also allows for the construction of complex, three-dimensional nanoscale structures.
For a variety of political and natural reasons, global warming affects some countries differently than others. Fragile economies and weak infrastructures tend to worsen the results of climate disruptions, a problem exemplified by Bangladesh’s vulnerability to monsoons, accelerating desertification in northern China, and, most visibly, Hurricane Katrina’s devastation in New Orleans. At the same time, warming and altered rainfall patterns may—temporarily—improve conditions for countries in extreme latitudes, increasing harvests in Canada and Russia for a few years. Similarly, intentional changes meant to fight global warming would also have differential results.
At the same time, the resources required for geoengineering projects can vary dramatically. A start-up company called Climos and the government of India have each begun to prepare tests of “ocean iron fertilization” to boost oceanic phytoplankton blooms, in order to extract carbon dioxide from the atmosphere, at a cost of just a few million dollars. At the other end of the spectrum, projects like the injection of megatons of sulfur dioxide into the upper atmosphere to simulate the effects of a volcano would easily cost in the tens of billions of dollars—still within the means of most developed countries.
A year ago to the day, China knocked a weather satellite out of orbit, and threw the international community into panic. Some figured the satellite-killer test was the harbinger of a future war in space — the kind of conflict that could cripple a tech-dependent United States military. Geoffrey Forden, PhD — an MIT research associate and a former UN weapons inspector and strategic weapons analyst at the Congressional Budget Office — examines the possibilities of an all-out Chinese assault on American satellites.

Although the underlying concepts of nanotechnology were thought up in 1959, only during the 1990s were the first tentative steps taken toward identifying and developing nanomaterials. “Between the end of the first decade of the 21st century and 2025, a number of gamechangers will need to occur if nanotech is to advance significantly,” von Stackelberg says. These gamechangers include:
A shift from “passive” to “active” nanotech. In the coming decades, nanotech will likely make the transition from simple nanomachines—particles, crystals, rods, tubes, and sheets of atoms—to more complex ones that contain valves, switches, pumps, and motors.
Nanoscale tools. To work at the nanoscale, new tools will be needed to allow researchers and technicians to see, measure, and manipulate individual atoms and molecules. “One promising approach uses dynamic light scattering, a technique that measures how much nanoparticles jiggle when hit with laser light,” von Stackelberg shares. “Many scientists agree that this method has the potential to do rapid, accurate measurement, and is expected to be operational by 2010.”
Nanofabrication. Currently, manufacturing processes for nanomaterials are extremely expensive, produce only small amounts of material, and generate a significant amount of impurities and waste, von Stackelberg says. “But consider this: Assembly of nanodevices today is at the same stage as the automobile industry was before Henry Ford developed the assembly line.”
Yes? No? Well, that’s how the 21st century looked to some futurologists 40 or 50 years ago, and they’re having a hard time living it down now. You can still get away (as we do) with predicting trends in the world next year, but push the timeline out much further, and you might as well wear a T-shirt saying “crackpot”. Besides, since the West began obsessing a generation ago about accelerating social and technological change, people in government and industry can spend weeks each year in retreats brainstorming and scenario-building about the future of their company or their industry or their world. The only thing special about a futurologist is that he or she has no other job to do.

IT is a chilling, dystopian account of what Britain will look like 10 years from now: a world in which Fortress Britain uses fleets of tiny spy-planes to watch its citizens, of Minority Report-style pre-emptive justice, of an underclass trapped in sink-estate ghettos under constant state surveillance, of worker drones forced to take on the lifestyle and values of the mega-corporation they work for, and of the super-rich hiding out in gated communities constantly monitored by cameras and private security guards.
