“The machines are being allowed to generate their own words because human language is so loaded with information that robots found it hard to understand, said project leader Dr Ruth Schulz…’Robot-robot languages take the human out of the loop,’ she said. ‘This is important because the robots demonstrate that they understand the meaning of the words they invent independent of humans.’“

In the most recent chapter of “Haven’t these scientists ever heard of Skynet?”, researchers at the University of Queensland are teaching robots to forge their own mutually-agreed-upon language. “Slowly, as the robots travel and talk, they narrow down their lexicon of place names until a mutual gazeteer of their world has been generated. The robots generated place names such as ‘kuzo’, ‘jaro’ and ‘fexo.’“

Back to the Future?

“Douglas Cooke, associate administrator of NASA’s Exploration Systems Mission Directorate, told reporters the Orion concept, described by former NASA Administrator Mike Griffin as ‘Apollo on steroids,’ is the most capable spacecraft currently on the drawing board for meeting the Obama administration’s ‘flexible path’ approach to deep space exploration.“

With the Space Shuttle nearing its end, NASA unveils the prototype for their new deep space exploration vehicle, Lockheed’s Multi-Purpose Crew Vehicle (MPCV), and, well, it’s a throwback alright. “As currently envisioned, the MPCV would support four astronauts on short-duration flights of less than 21 days. For longer missions to asteroids or even Mars, the capsules would dock with a larger spacecraft of some sort that would provide more room for the crew while in transit.” “Of some sort”? So far at least, I am underwhelmed.

The Wanderers.

“So what makes the astronomers think these are free-floating planets, and not ones orbiting stars like Earth does? Well, the lensing events themselves show only a single rise and fall of the background starlight. If the planets were orbiting stars, those stars would also act like lenses, and their effect would be seen. They weren’t.“

As explained by Discover‘s Phil Plait, a NASA-funded study using gravitational lensing finds possible evidence of billions of rogue planets wandering the cosmos between the stars. “In fact, these free-floaters may outnumber ‘regular’ planets by a factor of 1.5 or so. There are more of them than there are of us!…It’s thoughts that like which make me glad to be an astronomer, especially one living now. Just when you think the Universe is running low on surprises, it reminds us it’s a lot more clever than we are.”

And Thanks For All the Fish.

“At first, divers will play back one of eight “words” coined by the team to mean “seaweed” or “bow wave ride”, for example. The software will listen to see if the dolphins mimic them. Once the system can recognise these mimicked words, the idea is to use it to crack a much harder problem: listening to natural dolphin sounds and pulling out salient features that may be the ‘fundamental units’ of dolphin communication.“

As it happens, the iPad wasn’t the only modern technology predicted by Douglas Adams. Researchers at Georgia Tech and the Wild Dolphin Project develop a machine that will (hopefully) speak dolphin — or at least speak at dolphins. Says a skeptic: “‘Imagine if an alien species landed on Earth wearing elaborate spacesuits and walked through Manhattan speaking random lines from The Godfather to passers-by.’”

Still a Hoopy Frood.

“I suppose earlier generations had to sit through all this huffing and puffing with the invention of television, the phone, cinema, radio, the car, the bicycle, printing, the wheel and so on, but you would think we would learn the way these things work, which is this:

1) everything that’s already in the world when you’re born is just normal;

2) anything that gets invented between then and before you turn thirty is incredibly exciting and creative and with any luck you can make a career out of it;

3) anything that gets invented after you’re thirty is against the natural order of things and the beginning of the end of civilisation as we know it until it’s been around for about ten years when it gradually turns out to be alright really.“

In remembrance of Douglas Adams, ten years after his untimely passing: His 1999 essay, “How to Stop Worrying and Learn to Love the Internet” (although I think he too would have despised the term “webinar.”) If only he lived to see the actual, honest-to-goodness Hitchhiker’s Guides! (Pic via here, which also tells the story of Adams’ lost Doctor Who episodes.)

A Qward-er Hour of Science.

“The ALPHA team want to keep antimatter intact long enough to study it, so last year they worked out how to hold a cloud of antihydrogen in a magnetic trap. Not for long, though: collisions with trace gases would have either annihilated the anti-atoms or given them the energy to escape, so the team opened the trap after 170 milliseconds and observed the resulting annihilations, verifying that antimatter had been made.“

Building on the LHC’s success last November, scientists in Geneva, Switzerland manage to trap anti-matter for a full sixteen minutes, 10,000 times longer than ever before. “This time around, they used the same method but also cooled the antiprotons used to create the antihydrogen, which lowered the energy of the antimatter,but increased the chance that more could be collected.“

Space-Time in a Bottle.

“‘This is an epic result,’ adds Clifford Will of Washington University in St. Louis…’One day,’ he predicts, ‘this will be written up in textbooks as one of the classic experiments in the history of physics.’“

Using “the most perfect spheres ever made by humans,” a NASA experiment known as Gravity Probe B finds evidence of space-time curvature, as Einstein predicted under general relativity. “Everitt recalls some advice given to him by his thesis advisor and Nobel Laureate Patrick M.S. Blackett: ‘If you can’t think of what physics to do next, invent some new technology, and it will lead to new physics. Well,’ says Everitt, ‘we invented 13 new technologies for Gravity Probe B. Who knows where they will take us?’”

Ich Bin Ein Heidelbergensis.

“Although Homo heidelbergensis has generally been seen as a precursor to Neanderthals, its precise relation to us has been less clear. This fossil analysis is some of the most compelling evidence yet that we can in fact trace an evolutionary lineage back through Homo heidelbergensis.”

From a 400,000 year-old skull found in Ceprano, Italy, scientists believe they may have locked down humankind’s parent species. “The idea is that, aided by the favorable climates of the Middle Pleistocene starting around 780,000 years ago, Homo heidelbergensis spread far and wide throughout the Old World. Around 400,000 years ago, this mobility began to decrease and Homo heidelbergensis became more isolated, paving the way for the clear emergence of Neanderthals and modern humans in Eurasia and Africa respectively.“

Silence will Fall.

“‘There is a huge irony,’ said SETI Director Jill Tarter, ‘that a time when we discover so many planets to look at, we don’t have the operating funds to listen.’ SETI senior astronomer Seth Shostak compared the project’s suspension to ‘the Nina, Pinta and Santa Maria being put into dry dock.’…This is about exploration, and we want to keep the thing operational. It’s no good to have it sit idle.”

Another casualty of the lousy economy and the budget crises (in this case, California’s) SETI’s Allen Telescope Array goes dark. “‘We have the radio antennae up, but we can’t run them without operating funds,’ he added. ‘Honestly, if everybody contributed just 3 extra cents on their 1040 tax forms, we could find out if we have cosmic company.‘”

Mercury Rising.

“‘This is the last of the classical planets, the planets known to the astronomers of Egypt and Greece and Rome and the Far East,’ said Sean C. Solomon of the Carnegie Institution of Washington, the mission’s principal investigator. ‘It’s an object that has captivated the imagination and the attention of astronomers for millennia.’ But never before has science had such a good front-row seat. ‘We’re there now,’ Dr. Solomon said.” NASA’s Messenger sends back some photos of its fly by Mercury, a planet we haven’t visited since Mariner 10 in 1975.
