Astrobiologists find that the presence of oxygen in a planet’s atmosphere may not necessarily mean that life exists there.
Scientists and E.T. enthusiasts may have to rethink an allegedly telltale sign that a planet has life.
The presence of oxygen, specifically O2 , in a planet’s atmosphere has long been thought to be a near-certain signal that there are, or at least were, living organisms engaging in photosynthesis on the planet. But new research suggests that oxygen can exist in large quantities without being produced by living things.
A study published Thursday in Scientific Reports found that some planets could have “abiotic” oxygen, produced through a a photocatalytic reaction of titanium oxide
Valery Spiridonov who has put himself forward to have the world’s first head transplant is going to meet the surgeon. (CEN)
A man set to become the world’s first head transplant patient has scheduled the procedure for December 2017.
Valery Spiridonov, 30, was diagnosed with a genetic muscle-wasting condition called Werdnig-Hoffmann disease, and volunteered for the procedure despite the risks involved, Central European News (CEN) reported.
“When I realized that I could participate in something really big and important, I had no doubt left in my mind and started to work in this direction,” Spiridonov, a Russian computer scientist, told CEN. “The only thing I feel is the sense of pleasant impatience, like I have been preparing for something important all my life and it is starting to happen.”
Dr. Sergio Canavero, an Italian neurosurgeon, will perform the procedure on Spiridonov. The procedure is expected to last up to 36 hours, and it will require Spiridonov’s head be cooled as well as the donor’s body to extend the period during which the cells can survive without oxygen, CEN reported.
“According to Canavero’s calculations, if everything goes to plan, two years is the time frame needed to verify all scientific calculations and plan the procedure’s details,” Spiridonov told CEN. “It isn’t a race. No doubt, the surgery will be done once the doctor and the experts are 99 percent sure of its success.”
Spiridonov joked that first thing he plans to do after the procedure is go on a vacation.
“But on a serious note, this operation is aimed at restoring independence of severely disabled people. Once I get it back I’ll see what the life of a healthier person looks like,” he said.
BEIJING (AP) — China’s space program says it plans to attempt the first-ever landing of a lunar probe on the moon’s far side.
Zou Yongliao from the Chinese Academy of Sciences’ moon exploration department told state broadcaster CCTV on Wednesday that the Chang’e 4 mission is planned for sometime before 2020.
Zou said the objective of the mission would be to study geological conditions on the moon’s far side, also known as the dark side. Radio transmissions from Earth are unable to reach the far side, making it an excellent location to place a radio telescope for use by astronomers.
China’s next lunar mission is scheduled for 2017, when it will attempt to land an unmanned spaceship on the moon before returning to Earth with samples..
Conspiracy theorists are in a bit of a flutter after the discovery of what the believe is an alien corpse near a nuclear power plant.
The odd discovery of the apparent body with a “mysterious skull” in Russia has got UFO hunters excited at what could be evidence of life on other planets.
Either that or it’s a mutant chicken embryo – which is what experts first thought it might have been.
However, scientists believe that if it is a corpse, it isn’t from any known animal on the planet.
One said: “It seems that this body is neither fish nor fowl – this creature has a mysterious skull, no neck and wings.”
Experts from the Institute of Biophysics in Krasnoyarsk, where the body was taken for more tests, are equally baffled.
Biologist Yegor Zadereev said: “Extensive studies are needed to determine what kind of creature or organism it is.”
However, alien hunters are in no doubt what it is – an extraterrestrial.
Scott C Waring, from UFO Sightings Daily, said: “This tiny alien body was found near a river in Russia and has no resemblance to any animal known.
“Russian scientists are confused over what it could be and said they need to wait for the results of the tests, which are probably DNA I assume.”
To be fair, the body does look a bit like the aliens out of the Sigourney Weaver movies.
Though what it was doing poking around a nuclear power plant in the middle of Russia is anyone’s guess…

Lunar Transformer Concept
Announced yesterday, NASA is moving ahead with funding to study several ambitious space research projects, including one that would transform an inhospitable lunar crater into a habitat for robots — and eventually, human explorers. Located on the moon’s South Pole, Shackleton Crater isn’t just prime real estate for terraforming experiments, it’s Optimus Prime real estate. NASA wants to fill the crater with solar-powered transformers, and then use the fleet of robots to turn the crater into a miniature hospitable environment.
Shackleton Crater is uniquely qualified as a location for terraforming in the small scale. Named after the famous explorer of Earth’s own south pole, the crater covers about 130 square miles, or roughly twice the size of Washington, DC. It is surrounded on all sides by peaks that rise over 14,000 feet above the surface of the crater. Inside this moon-bowl, scientists have already found water, which is essential for any future human habitation.
Before the humans come the robots. To function, robots need electrical power and warmth, and with the right equipment, the sun can provide both, with a little help. In darkness, the crater is about 100 degrees Kelvin, or -280 fahrenheit, but a series of solar reflectors could capture light from the peaks on the crater rim and then reflect it down into the crater, warming and fueling solar-powered rovers at the same time.
These reflectors would be carried around the crater rim by other rovers, unfolding and transforming into useful shapes when needed. A single reflector 130 feet in diameter could send light over six miles into the crater, powering a rover (or a fleet of several Curiousity-sized rovers) with up to one megawatt of energy and preventing them from freezing. Thanks to their height, there is always at least one point on the peaks on the crater rim that receives sunlight, so work could be done continuously in the crater.
Should this plan all work out, several transforming robots with reflectors would work on the edge of the crater, beaming sun in, while robots inside the crater built something close to an “oasis” on the moon. Or at least, an oasis for lunar robots.
The project was awarded in NASA’s Phase II funding, which provides up to $500,000 for two-year-long studies, so the next task is designing a workable reflector that fits into a cube slightly larger than three feet each side, weighing less than 220 pounds, and that unfolds to cover 10,700 square feet. If it all works out, the robots shall inherit the moon.

Goal: 100 passengers, 1-hour intercontinental flights, with test flights by mid-2030s.
The Deutsches Zentrum für Luft- und Raumfahrt (DLR), Germany’s aerospace research center, has renewed decade-old plans for a suborbital passenger space plane that could fly from Europe to Australia in under 90 minutes. The rocket-powered SpaceLiner, originally conceptualized as a 50-passenger hypersonic airliner, has now been given new urgency and direction with a roadmap for flights within the next 20 years, SpaceLiner project lead Martin Sippel told Aviation Week at last month’s American Institute of Aerodynamics and Astronautics’ Space Planes and Hypersonics Conference in Glasgow. Sippel spoke at the conference, presenting on SpaceLiner’s technical progress and the program’s mission definition—which now includes potentially delivering satellites and other payloads to space.
In addition to providing a fairly exclusive passenger service—which would target an extremely small percentage of the international travel market—the goal of the program is to spur large-scale production of reusable rocket engines and booster vehicles that would reduce the cost of other space missions. “The point-to-point passenger market already exists and is growing,” Sippel told Aviation Week. “We have several hundred million passengers traveling intercontinental distances each year. But even if the share will only be 0.2 percent… from a space perspective that’s a potentially huge impact. We could increase hundredfold the number of launches and, as it is a reusable vehicle designed for between 150 and 300 flights, you have serial production of engines. If you have 11 engines per vehicle then you would build 2,000 engines per year or so. That’s a huge production run, and that was the motivation.”
The DLR SpaceLiner would launch upright with the assistance of an external booster, in a fashion similar to NASA’s now-retired Space Shuttle. The booster stage, equipped with its own wings, would be captured after use by a tow aircraft and then be released for an autonomous landing. The main vehicle would glide in a low orbit trajectory and then land like a normal aircraft at its destination, reaching a maximum speed of 4.3 miles per second. The goal size of the space plane is a 100-passenger vehicle, with the passenger compartment capable of ejection and flight on its own as an emergency measure. The reusable booster stage could also be used to ferry other vehicles to space, including launch systems for satellites to be placed in higher orbit.
The development of a flying prototype of the SpaceLiner could cost as much as $33 billion and would require multiple design reviews “before you build the first hardware in 2030,” Sippel said. Testing would involve up to six prototype vehicles, and actual commercial service wouldn’t begin until 2040. So please, don’t start calling Lufthansa to book a flight.
Technically incorrect: Robot sex has come a long way since the early days. But, boy, were those early days rough.
You probably can’t wait for your unreliable, moody, ill-mannered lover to be replaced by a sturdy, consistent, polite robot.
You’ve likely already experimented with a little robot sex. At least in your mind, surely.
But have you ever thought about those who came before you? Have you ever thought about the pioneers who began to conceive of a robot becoming your ultimate pleasure center?
Conan O’Brien decided to pay them and their hard work a tribute.
There was the creator of the Flappertron. Who could forget the man who invented Daddy’s Secret? And then there was the Gassy Chassis.
Each of these men — why were they all men? — deserve their place on the podium of progressive scientific thinking.
Many lost their dignity, if not their lives, in the pursuit of man’s pursuit of sexual satisfaction.
They toiled away in their laboratories, garages and, no doubt, bedrooms in order to bring us to where we are today, where there are at least 42 (allegedly) robots for you to have sex with (naturally, you should think twice about exploring that link while at work).
You might not feel the need for such mechanical companions right now. You may feel that your own companion is mechanical enough.
But these men’s work represents the future. These men will one day be revered for the contributions they made, the imagination with which they took to their task, and the sheer selflessness involved in helping you become involved with a robot.
These great scientists have ensured that no man will be left blissless. Just think how happy the future will be.
Above: A Boston Dynamics Robot walks in the woods.
Marc Raibert, the founder of Boston Dynamics, talked about and showed footage on the research during a talk on Aug. 3 at the 11th Fab Lab Conference and Symposium in Cambridge, Mass.
“Out in the world is just a totally different challenge than in the lab,” Raibert said at the conference, which was organized by the Fab Foundation, a division of the Massachusetts Institute of Technology’s Center for Bits and Atoms. “You can’t predict what it’s going to be like.”
Boston Dynamics has tested its LS3 quadruped (four-legged) robot out in natural settings in the past. But humanoid robots are different — they can be much taller and have a higher center of gravity. So keeping them moving through rugged terrain, as opposed to paved asphalt, which is what Boston Dynamics’ Atlas robots dealt with recently during the DARPA Robotics Challenge, can be more tricky.
See for yourself how this humanoid robot performs in the woods.

Perhaps the biggest component of the “Are we alone in the universe?” debate, for some, is the resulting dismantling of religious institutions here on Earth following inarguable proof that such institutions are decidedly anti-universe. For the religiously inclined, the question arises: Would inhabitants of another planet, likely within another universe entirely, even have knowledge of the respective god of one respective religion or another? The answer, of course, is a relatively firm “No.” Now, just three short centuries after the Catholic Church violently condemned Galileo for suggesting that Earth wasn’t the center of the universe, the Vatican Powers That Be are joining the realistic side of this debate.
Following NASA’s announcement of a possible Earth-like sister planet, Father José Gabriel Funes once again expressed his updated thoughts on the possibility of extraterrestrial life. “It is probable there was life and perhaps a form of intelligent life,” says Funes, director of the Vatican Observatory in Rome. “[Though] I don’t think we’ll ever meet a Mr Spock.” When pressed about the inherent contradictions of such an expression from a person of such devout Christian faith, Funes gives an admirably forthright response. “The Bible is not a scientific book. If we look for scientific responses to our questions in the Bible, we are making a mistake.”
Funes also believes, in a humorous act of deflection, that this theoretical extraterrestrial life likely aren’t Catholics, wouldn’t have the slightest clue as to who Jesus is, and most definitely haven’t experienced similar events of supposed religious importance. “The discovery of intelligent life does not mean there’s another Jesus,” offers Funes. “The Incarnation of the son of God is a unique event in the history of humanity of the universe.” That’s perfect, isn’t it? A powerful religious figure admits to the increasing likelihood of intelligent life elsewhere in the universe (i.e. aliens), but in the same breath reinforces the outmoded belief that humans are the center of everything.
Sorry, aliens. Please don’t visit us until we have our shit together.

Technically speaking, getting to space hasn’t become any easier over the past half century or so. It still requires using huge rockets to create a massive enough amount of force to push a payload beyond the grip of Earth’s gravity.
Enter the concept of the space elevator, which uses much simpler gravity-defying technologies to access space.
So far, most space elevator concepts have been the stuff of sci-fi, and any plans to actually build one have remained on the rather distant horizon. But “push button” access to space took a step toward reality in late July when the US Patent and Trademark Office granted a patent to a Canadian company for its invention of an inflatable space elevator tower.
Thoth Technology, based in Pembroke, Ontario, devised a tower design using pressurized segments that reach up to 20 kilometers (12.4 miles) into the stratosphere where a platform could be constructed for purposes of communications, tourism or as a launch platform for reaching space. Unlike blasting off from near sea level, as most space launches do now, getting into orbit or beyond from the top of a space elevator more than 20 times taller than the highest structures on Earth would be more like an aircraft takeoff.
“Astronauts would ascend to 20 km by electrical elevator. From the top of the tower, space planes will launch in a single stage to orbit, returning to the top of the tower for refueling and re- flight,” Brendan Quine, the inventor, said in a statement.
This elevator is far less ambitious than others we’ve reported on like plans from Japan’s Obayashi Corporation, which hopes to extend a space elevator quarter of the way to the moon by 2050.
The company sees space elevators leading to a new era of space travel when paired with other new technologies like self-landing rockets of the kind that SpaceX is working on.
Getting to that point will involve some new innovations that this patent doesn’t really address, however. The invention here is focused on the construction of the tower itself, but how to construct and maintain a strong, reliable elevator cable 12 miles long is the real challenge in the space elevator universe. In fact, it’s the focus of a space elevator conference taking place later this month.
The patent does suggest “the mechanism for elevating and lowering cars may be provided by frictional contact, at least one winch mechanism located along the length of the elevator core structure, or by inductive means” but each of those mechanisms would still need to be invented or customized to this design.
For now, we’re stuck having to ride fire to space, but the “slow space” movement is well under way and the invention of the new genre of space elevator music can’t be far behind.
