Using natural language programming (NLP), the software agents can read special English language technical documents on control methods. This gives the vehicles advanced guidance, navigation and feedback capabilities to stop them crashing into other objects and the ability to adapt during missions, identify problems, carry out repairs and make their own decisions about how best to carry out a task.

Professor Veres, who is leading the EPSRC-funded project, says: “This is the world’s first publishing system of technical knowledge for machines and opens the way for engineers to publish control instructions to machines directly. As well as spacecrafts and satellites, this innovative technology is transferable to other types of autonomous vehicles, such as autonomous underwater, ground and aerial vehicles.”

Professor Veres adds: “We have invented sysbrains to control intelligent machines. Sysbrain is a special breed of software agents with unique features such as natural language programming to create them, human-like reasoning, and most importantly they can read special English language documents in ‘system English’ or ‘sEnglish’. Human authors of sEnglish documents can put them on the web as publications and sysbrain can read them to enhance their physical and problem solving skills. This allows engineers to write technical papers directly for sysbrain that control the machines.”

Instead of focusing on building a better shield, engineers should design spaceships that can hop in and out of passing asteroids, argues study author Gregory Matloff, an adjunct professor of physics at the New York City College of Technology.

The asteroid itself could then block cosmic rays during the voyage—astronauts could pull a Millennium Falcon and park their ship in a crater, or they could use on-board mining tools to tunnel into the rock. (Related: “Obama’s New Plan for NASA: Why Go to an Asteroid?”)

According to Matloff’s calculations, to be published in the March-April 2011 issue of the journal Acta Astronautica, the asteroid “taxi” would need to be about 33 feet (10 meters) wide to provide enough shielding. It would also need to pass close enough to both planets—within a couple million miles—to make the trip feasible.

Already there are five known asteroids that fit the criteria and will pass from Earth to Mars before the year 2100, based on a database of 5,500 near-Earth objects (NEOs), or comets and asteroids whose orbits take them near our planet.

The asteroids 1999YR14 and 2007EE26, for example, will both pass Earth in 2086, and they’ll make the journey to Mars in less than a year. The trouble would be getting home: Because of their wide orbits, it’d be five years before either asteroid would swing around Mars as it heads back toward Earth.

Matloff did find a third space rock that will travel from Mars to Earth—but it makes the journey too early, in 2037. For now it seems a space taxi to Mars would be a one-way ride.

However, the number of NEOs has increased since the database was compiled, Matloff said. There are now more than 7,000 known NEOs, so more potential rock taxis could exist.

Ideally, astronauts would divert an asteroid so that it cycles permanently between Earth and Mars on a well-timed orbit. Humans could nudge an asteroid into the desired path using a solar sail or gentle propulsion. (See “Solar Sail Hybrid Launches From Japan.”)

Once the asteroid is in a stable orbit, Matloff said, “you’d just jump on it. You could store provisions and spare parts on it and use it for shielding. … ”

AOL gave you $315 million: We’re asking you to give a little back to the unpaid writers who built the Huffington Post.

Outraged that Huffington Post brass is getting filthy rich off unpaid labour, writers flock to Facebook—a site whose entire multibillion valuation is based on the unpaid contributions and data of users—to demand justice.

Amazing.

So how did this happen? You don’t have to look far to find out. Almost all the members of the seven committees the government set up “to provide strategic oversight of the development of corporate tax policy” are corporate executives. Among them are representatives of Vodafone, Tesco, BP, British American Tobacco and several of the major banks: HSBC, Santander, Standard Chartered, Citigroup, Schroders, RBS and Barclays.

In a paper published online Feb. 7 in the UK Institute of Physics journal Physical Biology, Davies and Charles Lineweaver from the Australian National University draw on their backgrounds in astrobiology to explain why cancer cells deploy so many clever tricks in such a coherent and organized way.

They say it’s because cancer revisits tried-and-tested genetic pathways going back a billion years, to the time when loose collections of cells began cooperating in the lead-up to fully developed multicellular life. Dubbed by the authors “Metazoa 1.0,” these early assemblages fell short of the full cell and organ differentiation associated with modern multicellular organisms – like humans.
But according to Davies and Lineweaver, the genes for the early, looser assemblages – Metazoa 1.0 – are still there, forming an efficient toolkit. Normally it is kept locked, suppressed by the machinery of later genes used for more sophisticated body plans. If something springs the lock, the ancient genes systematically roll out the many traits that make cancer such a resilient form of life – and such a formidable adversary.
“Tumors are a re-emergence of our inner Metazoan 1.0, a throwback to an ancient world when multicellular life was simpler,” says Davies. “In that sense, cancer is an accident waiting to happen.”

Syrian authorities are to lift a five-year ban on Facebook in a move seen as an apparent “appeasement” measure, aimed at staving off unrest in the country following recent political developments in Egypt and Tunisia.

In a rare and candid interview, President Bashar al-Assad told the Wall Street Journal last week that he would push through political reforms this year aimed at initiating municipal elections, granting more power to non-governmental organisations and establishing a new media law.

Scientists suspect the lake’s depths will reveal new life forms, show how the planet was before the ice age and how life evolved. It could offer a glimpse at what conditions for life exist in the similar extremes of Mars and Jupiter’s moon Europa.

“It’s like exploring an alien planet where no one has been before. We don’t know what we’ll find,” said Valery Lukin of Russia’s Arctic and Antarctic Research Institute (AARI) in St Petersburg, which oversees the expedition.

…not only is the network more powerful than the hierarchy – but the ad-hoc network has become easier to form. So if you “follow” somebody from the UCL occupation on Twitter, as I have done, you can easily run into a radical blogger from Egypt, or a lecturer in peaceful resistance in California who mainly does work on Burma so then there are the Burmese tweets to follow. During the early 20th century people would ride hanging on the undersides of train carriages across borders just to make links like these.

Today, faced with the limits of the internet, digital activists are reviving such ideas. One of them, “mesh networking,” would let people connect simply by opening their Wi-Fi networks to incoming traffic. The inhabitants of an entire city could be connected to one another, without anyone even having an internet service provider. Then that city can connect to another, and so on.

Until we choose to develop such alternative networks, our insistence on seeing the likes of Facebook and Twitter as the path toward freedom for all people will only serve to increase our dependence on corporations and government for the right to assemble and communicate.

Experts have discovered the remains of a 1900-yr-old, 15ft-high Roman super-highway in the UK that ran from London to Exeter.

The road, found in the depths of a forest in Dorset, shows no sign of the potholes that blight our modern roads.

Constructed by the Roman invaders as part of a route from London (Londinium) to Exeter (Isca), the 85ft wide earthwork stands more than 15ft high and consists of a sweeping road with deep ditches at the side.

It was found when the Forestry Commission, acting on advice from English Heritage expert Peter Addison, cleared the Norway spruce fir trees in Puddletown Forest.

The section uncovered is made of gravel with a central cobbled ‘street’, which would have been used for rapid troop movements, and outer ‘droving’ roads for livestock, as well as ditches for water drainage.
