All (known) Bodies in the Solar System Larger than 200 Miles in Diameter


I've always been a sucker for visualizations that show the relative scale of things. I think it's good for all of us to realize just how fragile and insignificant our little planet is. This image certainly accomplishes that.

The larger planets and Sun just bleed off the page, but still give a sense of scale by the visible curve of their limbs. And where to cut it off on the small end? Why 200 miles? Well, that's entirely arbitrary. It so happens that I have a fondness for Saturn's moon Mimas (247 miles across), and 200 was the next round number down. That simple. Also, it captures a fair percentage of known Trans-Neptunian Objects (51), enough to give a good idea of their place in the larger scheme of things.

Bill Richardson: Super Genius

Prepare yourselves. This is what we have to look forward to until the next election.

In a speech to the Nitze School of Advanced International Studies at Johns Hopkins University, democratic presidential candidate Bill Richardson made the bold statement that "If al-Qaida obtained nuclear weapons, they would not hesitate to use them with the same ruthlessness that allowed them to fly airplanes filled with people into buildings." He said we should secure nuclear materials in Russia and other dangerous areas of the world so they can't get in terrorists hands.

So you're taking the controversial position that we should probably try to keep nuclear materials away from terrorists? That's really out-of-the-box thinking there Bill, although I see no mention of how the US is supposed to accomplish this. Still, the full extent of your genius was not revealed until later.
In the question-and-answer period after his speech, Richardson laid out the plans for his first days in the White House. The first day, he would get out of Iraq. The second, he would announce a plan to drastically cut U.S. dependence on foreign oil.On the third day, the issue would be global warming.
That's amazing! You can fix all the problems in the middle east, cut our dependence on oil and solve global warming all in your first three days? What are you going to do the rest of the week? Restore the rainforests? Free medical care? Flying cars and jetpacks in every garage? I can't wait!

Flaming Space Junk Narrowly Misses Jet

An airliner heading for Auckland, New Zeland was rattled by a Russian satellite deorbiting.
Pieces of space junk from a Russian satellite coming out of orbit narrowly missed hitting a jetliner over the Pacific Ocean overnight.

The pilot of a Lan Chile Airbus A340, which was travelling between Santiago, Chile, and Auckland, New Zealand, notified air traffic controllers at Auckland Oceanic Centre after seeing flaming space junk hurtling across the sky just five nautical miles in front of and behind his plane about 10pm last night.

According to a plane spotter, who was tuning into a high frequency radio broadcast at the time, the pilot "reported that the rumbling noise from the space debris could be heard over the noise of the aircraft.
The article goes on to say that the Russians had warned the Airline about two weeks in advance, but the satellite came down about a half hour sooner than predicted in the warning. I wonder if it's routine for airlines to be notified of space junk?

Unknown Object Falls Into Somalia

According to this story, an unknown object that "gives alarming signals" has landed in a remote area of Somolia, killing a camel in the process.
(SomaliNet) A baffling device which resembles a satellite or Unidentified Flying Object (U.F.O) has landed in a rural area close to Buulo-Burde town, 220km north of the Somalia capital Mogadishu, eyewitnesses told Shabelle radio on Monday.

Villagers report that the device had fallen in a remote jungle area, some 40km north of Bulo-Burde, killing one camel. No experts have reached there to find out exactly what the object is.

The unknown object is sitting on an area of one 100 meter square as people grew more concern over the device that it might explode or contaminate the area.

The device is said to be intact and not broken as it gives alarming signals. No one knows where the satellite-like device had come from.

Roach In The News

Listening to the radio on my drive to work this morning, I was surprised to hear several different news stories all featuring my surname.

The AP reported that "Wynonna Judd said she filed for divorce Tuesday from her estranged husband, Dan R. Roach, after his arrest in Texas on sex charges involving a minor. Roach was arrested Thursday in Abilene and charged with three counts of aggravated sexual battery against a child younger than 13, according to Nashville police."

The second story, also from AP, concerns one Lawrence Roach. "Roach and his wife, Julia, divorced in 2004 after 18 years of marriage. The 48-year-old utility worker agreed to pay her $1,250 a month in alimony. Since then, Julia Roach, 55, had a sex change and legally changed her name to Julio Roberto Silverwolf.
"It's illegal for a man to marry a man and it should likewise be illegal for a man to pay alimony to a man," said John McGuire, one of Roach's attorneys. "When she changed to man, I believe she terminated that alimony."

Silverwolf?

By the way, there is no relation (at least that I'm aware of) between these people and my own family.

Bizarre Hexagon At Saturn's Pole


The Cassini orbiter has imaged a wierd hexogonal structure at Saturn's north pole.
In the new infrared images, the strong brightness of the hexagon feature indicates that it is primarily a clearing in the clouds, which extends deep into the atmosphere, at least some 75 kilometers (47 miles) underneath the typical upper hazes and clouds seen in the daytime imagery by Voyager. Thick clouds border both sides of the narrow feature, as indicated by the adjacent dark lanes paralleling the bright hexagon. This and other images acquired over a 12-day period between Oct. 30 and Nov. 11, 2006, show that the feature is nearly stationary, and likely is an unusually strong pole-encircling planetary wave that extends deep into the atmosphere.
I looked up "planetary wave", also known as a Rossby wave, and found it is a type of inertial wave possible in rotating fluids. Unlike the waves we're familiar with at the beach, an inertial wave travels through the bulk of the fluid, not the surface. Cool.

Augmented Cognition


Augmented Cognition, or AugCog, is likely to be the first step towards greater than human intelligence. According to the Augmented Cognition International Society (run by an alphabet soup of government and military acronyms, including DARPA) AugCog:
"...seeks to extend a user's abilities via computational technologies, which are explicitly designed to address bottlenecks, limitations, and biases in cognition and to improve decision making capabilities. The goal of AugCog science and technology is to develop computational methods and neurotech tools that can account for and accommodate information processing bottlenecks inherent in human-system interaction (e.g., limitations in attention, memory, learning, comprehension, visualization abilities, and decision making)".
They've produced a very slick, Hollywoood quality video showing a fictional 2030 Cyberspace Monitoring Organization "command center that is tasked with monitoring cyberspace activities for anomalies that could threaten the global economy". CMO sounds so sterile. They should have stuck with its traditional name - Illuminati.

Human-Sheep Chimeras



Scientists at the University of Nevada have created a human-sheep chimera by injecting human cells into a sheep foetus. The idea is to eventually create organs suitable for transplant into humans. About 15% of the cells are human.

But the development is likely to revive criticisms about scientists playing God, with the possibility of silent viruses, which are harmless in animals, being introduced into the human race.

Dr Patrick Dixon, an international lecturer on biological trends, warned: "Many silent viruses could create a biological nightmare in humans. Mutant animal viruses are a real threat, as we have seen with HIV."

Animal rights activists fear that if the cells get mixed together, they could end up with cellular fusion, creating a hybrid which would have the features and characteristics of both man and sheep. But Prof Zanjani said: "Transplanting the cells into foetal sheep at this early stage does not result in fusion at all."
Dr. Moreau was unavailable for comment. (And yes, I know this process won't result in anything like the accompanying photo).

Biomechanical Plants

The blending of genetic engineering, biotechnology, nanotechnology and robotics/AI will probably bring organisims like this in the not too distant future.

I don't have any information about who created this video or why, but I think you'll agree it's very well done!

Sean Penn - Actor, Poet, Statesman

I normally don't give a damn about what Sean Penn (or any celebrity) has to say, but he used such a colorful turn of phrase at an Oakland Califorina town hall meeting this weekend that I had to blog it.
"You have broken our country; you have broken our hearts. The needless blood on your hands ... is drowning the freedom, the security and the dream that America might have been, once healed up from Sept. 11, 2001," Penn said.

"But now we are encouraged to self-censor any words that might be perceived as inflammatory, if our belief is that we should stop this war today. We cower as you point your fingers telling us to support our troops -- well, you and the smarmy pundits in your pocket -- those who bathe in the moisture of your blood-soaked underwear can take that noise and shove it, because we will be snowed no more."
The phrase "those who bathe in the moisture of your blood-soaked underwear" has got to be the funniest thing I've heard since he was satirized in Team America: World Police.
"Last year I went to Iraq. Before Team America showed up, it was a happy place. They had flowery meadows and rainbow skies, and rivers made of chocolate, where the children danced and laughed and played with gumdrop smiles."
Note that although I mock Mr. Penn I defend his right to say anything he wants to say, as well as my right to make fun of it. Hurrah for Free Speech!

How Beautiful We Were

I love lists. American Digest contains "a short list, in no particular order" that serves as a bittersweet summary of the American experience, or at least how some Americans percieve it. As George Harrison observed, "All things must pass".

And the wind shifts
and the dust on a door sill shifts
and even the writing of the rat footprints
tells us nothing, nothing at all
about the greatest city, the greatest nation
where the strong men listened
and the women warbled: Nothing like us ever was.


- Carl Sandburg

An Alternative Architecture For Lunar Exploration

NASA is exploring a slightly different architecture for new manned lunar exploration. The existing plan would require the EDS (Earth Departure Stage) to sit in Earth orbit, possibly for months, awaiting the Orion Crew Exploration Vehicle. Storing cryogenic fuels in orbit for so long jacks up weight and complexity. In the alternate architecture, instead of docking to an EDS in Earth orbit, the Artemis lander and the Orion would each go direct to the moon and dock in lunar orbit.
The new booster could eliminate the Ares V and its EDS. Instead a second Ares IV launch would send the lunar lander, possibly named Artemis, directly to the Moon. After two Ares IV launches, one for Orion and one for Artemis, the vehicles would rendezvous and dock in lunar orbit. In the Apollo programme the crew and service module spacecraft docked with the lunar module in Earth orbit.

Foot Fetishist's Dream?

This is quite a bit off the beaten path from my usual blog fodder, but I just have to post it. I hope it doesn't offend anyone.
A 22-year-old woman sought medical care for a lesion in the plantar region of her left foot, a well-formed nipple surrounded by areola and hair. Microscopic examination of the dermis showed hair follicles, eccrine glands, and sebaceous glands. Fat tissue was noted at the base of the lesion. Clinical and histopathologic findings were consistent with the diagnosis of supernumerary breast tissue, also known as pseudomamma. To our knowledge, this is the first report of supernumerary breast tissue on the foot.

A Blimp With Muscle

Artificial muscles have the potential to revolutionize robotics. So far, they aren't very powerful or durable, but they're slowly improving and finding applications, as detailed in this New Scientist article.
Researchers believe artificial muscles – plastics that stretch when a high electrical voltage is applied – could be a way to mimic nature's efficiency at accomplishing tasks. Using the technology, future robots may be able to "run on Mars like a cheetah, climb a mountain or a cliff like a gecko, or fly like a bird", says Yoseph Bar-Cohen, a physicist at NASA's Jet Propulsion Laboratory in Pasadena, California, US.

Now, a team from the Swiss Federal Laboratories for Materials Testing and Research in Dübendorf have developed a 6-metre-long blimp steered by artificial muscles.
This week, the team directed the blimp's rudder to steer the airship left, right, up or down at the International Society for Optical Engineering's Electroactive-Polymers Actuators and Devices conference in San Diego, California, US. The blimp is currently able to fly for only 20 minutes on its battery.

Silvain Michel, head of the electroactive polymers department at the laboratory, hopes to fly a blimp that is not only steered but also powered by artificial muscles within two years. The blimp's tail would wriggle like a trout to propel it through the air.

Michel said the blimps could be used for wildlife or crowd observations in place of noisy helicopters. "If this is possible, then we would have a very quiet, very efficient propulsion system for an airship," Michel told New Scientist.

Lisa Nowack Update

The AP reports:

Lisa Nowak's trial has been scheduled for a two-week period starting July 30, said Danielle Tavernier, a spokeswoman for State Attorney Lawson Lamar.

Nowak, a mother of three who is separated from her husband, was arrested in February after allegedly confronting Colleen Shipman, the girlfriend of astronaut Bill Oefelein, in an Orlando airport parking lot. She drove from Houston, wearing an astronaut diaper so that she would not have to stop during her 900 mile (1,448-kilometer) trip, authorities said.
Interesting that they don't mention the pepper spray, BB gun, knife, steel mallet and rubber tubing - indications of evil intent. No, the real story here is the diapers - every story must mention the diapers. Well, what should I expect from a media which keeps us focused on triva while paying only lip service to real issues. Not that I'm cynical or anything.

Chemical Communications

Imagine you are on a military recon mission. You've found where the bad guys live. You know where the hidden arms cache is. You know where the locals must be protected. You need to tag these locations in a way that is unnoticed by the enemy but can be easily seen and read by the good guys.

You take out a device about the size of a cell phone or PDA, and enter a message up to 60 characters long. The device translates the message into a set of modulated chemistry (yes, chemistry), embeds them on piece of paper, and ejects the paper. You take the piece of paper (covered with an adhesive backing), stick it on an unobtrusive spot, and move on.

Chemical reactions on the paper cause it to glow in a narrow infrared band visible only to special equipment. The chemical reactions are designed to modulate the glow so as to transmit the encoded message. This chemically powered optical transmitter continues to broadcast the message for 100 hours, so when the Good Guys arrive, they know exactly where to go and where to avoid.

A Request For Proposals to build such a device has just been let by DARPA. You can read all about it here.

A Biocentric and Holographic Universe

I recently stumbled across an intriguing interpretation of the implications of quantum physics. I thought this fit rather nicely with some other theories I've come upon, so I decided to attempt to integrate them.

In the American Scholar article "A New Theory of the Universe", Dr.Robert Lanza tells physicists they've been barking up the wrong tree. Lanza is a leading expert in tissue engineering, cloning and stem cell research. He is not a physicist and so is likely to be ignored by the physics community. Yet, he may be on to something.
"The urgent and primary questions of the universe have been undertaken by those physicists who are trying to explain the origins of everything with grand unified theories. But as exciting and glamorous as these theories are, they are an evasion, if not a reversal, of the central mystery of knowledge: that the laws of the world were somehow created to produce the observer. And more important than this, that the observer in a significant sense creates reality and not the other way around. Recognition of this insight leads to a single theory that unifies our understanding of the world.
...As unimaginable as it may seem to us, the logic of quantum physics is inescapable. Every morning we open our front door to bring in the paper or to go to work. We open the door to rain, snow, or trees swaying in the breeze. We think the world churns along whether we happen to open the door or not. Quantum mechanics tells us it doesn’t.

The trees and snow evaporate when we’re sleeping. The kitchen disappears when we’re in the bathroom. When you turn from one room to the next, when your animal senses no longer perceive the sounds of the dishwasher, the ticking clock, the smell of a chicken roasting—the kitchen and all its seemingly discrete bits dissolve into nothingness—or into waves of probability. The universe bursts into existence from life, not the other way around as we have been taught. For each life there is a universe, its own universe. We generate spheres of reality, individual bubbles of existence."
I think this fits well with the notion of a holographic universe. Consider a transmission hologram. At first it appears to be simply an interference pattern, but when illuminated with a laser a fully realized 3D object pops into view. In a similar way, the universe exists as an interference pattern of probability waves. When a portion of the pattern is "lit up" by an observer it generates what we perceive as physical reality. Perhaps each bubble generates an "image" of the whole universe, just as individual pieces of a hologram that has been cut apart retain the entire image, but with some loss of detail.

There is some theoretical support for a holographic universe. Per Wikipedia, "The holographic principle is a speculative conjecture about quantum gravity theories, proposed by Gerard 't Hooft and improved and promoted by Leonard Susskind, claiming that all of the information contained in a volume of space can be represented by a theory that lives in the boundary of that region."

I'm going to try and paraphrase the Wikipedia description of the reasoning so we don't get too bogged down:

The entropy that can be contained in any given volume of space can not be any larger than the entropy of the largest black hole that can fit in that space. The more massive the black hole, the larger the surface area of the event horizon. This means the maximum entropy for any region of space is determined by surface area, not by volume. This is counter-intuitive because entropy is an extensive variable, being directly proportional to mass, which is proportional to volume (all else being equal, including the density of the mass). If entropy of ordinary mass is also proportional to area, this implies that volume itself is somehow illusory: that mass occupies area, not volume, and so the universe is really a hologram which corresponds to the information encoded on its boundaries.

Then there are the philosophies of David Bohm, the quantum physicist who wrote "Wholeness and the Implicit Order"
Bohm suggests that the whole universe can be thought of as a kind of giant, flowing hologram, or holomovement, in which a total order is contained, in some implicit sense, in each region of space and time. The explicate order is a projection from higher dimensional levels of reality, and the apparent stability and solidity of the objects and entities composing it are generated and sustained by a ceaseless process of enfoldment and unfoldment, for subatomic particles are constantly dissolving into the implicate order and then recrystallizing.
More on David Bohm later.

Cockroach Decapitation

Scientific American has a short but interesting article concerning the oft-repeated claim that a cockroach can live for weeks withoug a head. Well, it turns out that's true - and the head can live without the body for an extended time as well. In fact, this ability is used in scientific studies.
Cockroach decapitation may seem macabre, but scientists have conducted many experiments with headless roach bodies and bodiless roach heads. Decapitating roaches deprives their bodies of hormones from glands in their heads that control maturation, helping researchers investigate metamorphosis and reproduction. And studies of bodiless roach heads shed light on how their neurons work. Plus, it provides just one more testament to the cockroach's enviable endurance.
The article goes into detail about just how the cockroach is able to survive in this condition.

AstroRoach Now On Twitter

I've been hearing raves about a new online community service called Twitter, so I decided to give it a try. You'll notice a new "AstroTwitter?" window in the sidebar. I can update this from one of several IM clients, the Twitter web page, or my mobile phone. You can view the entries either here or at www.twitter.com/astroroach

According to the FAQ, "Twitter is a community of friends and strangers from around the world sending updates about moments in their lives. Friends near or far can use Twitter to remain somewhat close while far away. Curious people can make friends. Bloggers can use it as a mini-blogging tool. Developers can use the API to make Twitter tools of their own. Possibilities are endless!"

Since my life could scarely be more uninteresting, I doubt much will come of it, but we'll see what happens.

Just One More Post On Global Warming

Well, I've finally seen "An Inconvenient Truth", and found it to be a mixed bag. Although it was a compelling presentation, I could have done without the political advertisements. I guess I'm supposed to conclude that Al Gore, denied the chance to guide us to ecological paradise by hanging chads and the Supreme Court, decided that the only way he could save the world from certain global disaster was with a slide show.

I'm wary anytime someone speaks in absolute terms. We're told there is zero scientific disagreement about how the temperature and CO2 data were derived; how the data correlates; or the predicted effects over the next 50 years. In reality about all we can say for sure is that CO2 appears to be related to global temperatures; that CO2 levels are likely to continue to rise; and this will probably result in higher temperatures. Now, that's an important message to be sure, but that's not the message presented. Instead, Gore decided it's much more interesting to represent yourself as the Messenger Of Truth, revealing hidden knowledge with certainty and conviction.

There seems to be something of a backlash against Gore in the media. It's predictable really. Hollywood likes to put people on a pedestal so they can have the pleasure of knocking them down. It doesn't matter if it's an Al Gore or a Britney Spears.

The VentureOne Hybrid


Introducing the VentureOne, a revolutionary 3-wheel, tilting, plug-in Hybrid vehicle. This unique 2-passenger flex-fuel Hybrid vehicle will achieve 100 miles per gallon with a top speed of over 100 mph. Target price: $18,000.

Although classified as a motorcycle, the VentureOne is a fully enclosed vehicle that is surrounded by a steel “safety cell” and other safety features typically found only in cars—things like side impact beams, driver airbag, rear bumper and engine shield. In addition, the VentureOne will contain standard and optional equipment identical to conventional motor vehicles – including GPS navigation, cruise control, HVAC, and personal entertainment.

A QuickTime video from Top Gear shows just how much fun driving this type of vehicle can be. As someone who commutes almost 100 miles a day, I'd probably buy this in a heartbeat if it has a reasonably comfortable ride.

AstroRoach Visitor Map

One of the most unexpected aspects of this blog is the fact that I have a worldwide audience. About one-third of you are connecting from outside the United States; so far this year, AstroRoach has had visitors from 67 countries on every continent.

Since AstroRoach readers are scattered across the world, I thought it would be fun to create a Frappr map for the AstroRoach "community". Although the map will track connections anonymously, I encourage you to join Frappr so you can upload a picture and a message.

Dean Kamen's Bionic Arm

It's worth watching this poor quality video of a video, taken at the 2007 TED (Technology, Entertainment, Design) Conference. In it, Dean Kamen demonstrates his amazing new bionic arm.

The San Francisco Chronicle describes his motivation.

Kamen had been approached by a government official who requested his help to improve the current solution for soldiers who have lost their arms, which he said is currently not much more than a stick with a hook.

"I don't need another mission," said Kamen, who visited the Walter Reed hospital a few weeks ago. "But I kept thinking of these kids with no arms."

In one instance, Kamen said, he met a soldier sitting at a table who said he was lucky because he had lost his left arm, not his right, dominant arm. Then the soldier pushed away from the table and Kamen said he was also missing his two legs.
Inspired by the tremendous courage he had seen, Kamen set out to develop the most advanced prosthetic ever. Obviously there are extremely precise control and feedback mechanisms, but just how the arm is controlled wasn't stated. Kamen did say that brain implants were a bad idea, although he's pursuing the idea of implants developed from stem cells which would be implanted elsewhere in the body.

For those that don't know, Dean Kamen is a superhero. His house, which he designed, is powered by a giant wind turbine which sits outside, alongside a fully-lit baseball diamond. In the garage are a Hummer, a Porsche and two helicopters. They sit on a giant turntable, Batman-style. He flies one of the choppers every day to his office a few minutes away at his research company DEKA. Kamen also owns an island off the coast of Connecticut, which he calls North Dumplinga. It has it's own currency and boasts a mutual non-aggression pact with the US signed by Mr Kamen and President Bush senior.

So, he's got money, supercool toys, a sense of humor and a brilliant mind that he's applied towards making the world a better place. The drug infusion pump, portable dialysis machine, and iBOT robotic wheelchair are some of his most notable inventions, and of course he's know as creator of the Segway.

Recognizing that the US has fallen behind much of the rest of the world in graduating engineers, he formed FIRST:For Inspiration and Recognition of Science and Technology. Kamen saw that today's kids don't know a real hero from a celebrity, entertainer or sports figure, and created FIRST to attempt to change the culture. His vision is "To create a world where science and technology are celebrated... where young people dream of becoming science and technology heroes" by using the metaphor of sports competition.

And he even holds his own on the Colbert Report. Dean Kamen ROCKS!!!

Mind-Control Microbe


Do you think parasites that control the minds of their hosts is strictly sci-fi? Would you believe that some 60 million Americans may be under such influence? Discover Magazine has the skinny:
Five years ago, Oxford University zoologists showed that the parasite Toxoplasma gondii alters the brain chemistry of rats so that they are more likely to seek out cats. Infection thus makes a rat more likely to be killed and the parasite more likely to end up in a cat—the only host in which it can complete the reproductive step of its life cycle. The parasite also lives in the brain cells of thousands of species, including about 60 million supposedly symptom-free Americans. Studies over the past few years have suggested that toxoplasmosis infections in humans, too, may cause behavioral changes—from subtle shifts to outright schizophrenia. Two studies this year add even weirder twists.

U.S. Geological Survey biologist Kevin Lafferty has linked high rates of toxoplasmosis infection in 39 countries with elevated incidences of neuroticism, suggesting the mind-altering organism may be affecting the cultures of nations.

Stranger still, parasitologist Jaroslav Flegr of Charles University in Prague thinks T. gondii could also be skewing our sex ratios.

Global Warming vs. The Singularity

A draft report from the UN's Intergovernmental Panel on Climate Change (IPCC) takes the dry science from a report issued last month and presents it as a prediction of how global warming will change life on Earth. The major points are covered in this article from the AP:
WASHINGTON (AP) - The harmful effects of global warming on daily life are already showing up, and within a couple of decades hundreds of millions of people won't have enough water, top scientists will say next month at a meeting in Belgium.

At the same time, tens of millions of others will be flooded out of their homes each year as the Earth reels from rising temperatures and sea levels, according to portions of a draft of an international scientific report obtained by The Associated Press.

Tropical diseases like malaria will spread. By 2050, polar bears will mostly be found in zoos, their habitats gone. Pests like fire ants will thrive.

For a time, food will be plentiful because of the longer growing season in northern regions. But by 2080, hundreds of millions of people could face starvation, according to the report, which is still being revised.
Oh no! Fire Ants! Everybody panic! I'm suprised they didn't mention "killer" bees since they'll be moving further north.

Even assuming the IPCC is completely correct in their assessment of Global Warming, their analysis is bogus. In these predictions we see that even scientists fail to grasp Kurzweil's Law of Accelerating Returns and its ramifications.

In the unlikely event humanity survives to 2050, the world by that time will contain non-human superintelligence, and therefore is not predictable (the essence of the Singularity). Will global warming cause the predicted effects? Who cares? We have a great deal more to worry about than that.

If we don't address the existential risks facing humanity, climate change won't matter. And if we do find a way to survive, climate change will be a trival problem to solve.

Code Of Ethics For Robot Use


Hey man, the Singularity Is Near - look busy!

South Korea is creating a "Robot's Rules of Order" for the use of intelligent robots. I appreciate what they're trying to do, but I don't think they fully grasp the consequences. I'm pretty sure they are envisioning AI roughly on par with human intelligence.

A draft of the proposals said: "In the 21st Century humanity will coexist with the first alien intelligence we have ever come into contact with - robots. "It will be an event rich in ethical, social and economic problems." Oh really?

From the BBC:


An ethical code to prevent humans abusing robots, and vice versa, is being drawn up by South Korea. The Robot Ethics Charter will cover standards for users and manufacturers and will be released later in 2007.

It is being put together by a five member team of experts that includes futurists and a science fiction writer.

The South Korean government has identified robotics as a key economic driver and is pumping millions of dollars into research.

"The government plans to set ethical guidelines concerning the roles and functions of robots as robots are expected to develop strong intelligence in the near future," the ministry of Commerce, Industry and Energy said.

Lisa Nowak "Fired" By NASA


Well, not exactly fired. Since Astronaut Lisa Nowak is still in the Navy and just on a "detail", NASA requested the Navy to reassign her. Space.com has the details on the detail.
Because she is a military officer, and not a civil servant, Nowak’s status falls under the jurisdiction of the U.S. Navy and is not subject to any administrative actions by the space agency, NASA officials said. Nowak will now shift to her next Navy assignment, NASA officials said.

“She has orders, and she will be assigned to the staff of the chief of Naval Air Training in Corpus Christie, Texas effective March 21,” Commander Lydia Robertson, a U.S. Navy spokesperson, told SPACE.com.
By the way, the accompanying photo shows Lisa holding an award from a group called NOIAW, the National Organization of Italian American Women. It seems Lisa was the First Italian-American Woman In Space. Not that there's anything wrong with that.

Lust In Space


Colleen Shipman (pictured), the "other woman" in Lisa Nowak's love triangle.
ORLANDO, Florida (AP) -- NASA astronaut Lisa Nowak's bizarre 900-mile (1,450 kilometer) road trip to confront a romantic rival may have been sparked when she uncovered steamy e-mails sent to her boyfriend by the other woman, documents released Monday showed.

Nowak had collected more than a dozen e-mails sent to her one-time boyfriend, space shuttle pilot Bill Oefelein, including one he received during his shuttle mission, according to the documents, released late Monday by the Orange-Osceola State Attorney's Office.

“First urge will be to rip your clothes off,'' Air Force Capt. Colleen Shipman wrote to Oefelein while he was aboard shuttle Discovery in December. “But honestly, love, I want you to totally and thoroughly enjoy your hero's homecoming.''
Sounds like he totally and thoroughly enjoyed it to me.

Speed Of Light Exceeded?


The CBC is reporting that NEC researchers have designed an experiment that is the "first ever evidence of faster-than-light motion". I don't think so Bubba. I haven't seen their paper, but based on the CBC description it sounds as if they are describing the group velocity of the waveform. In certain media group velocity can exceed the speed of light although it doesn't carry information. This is nothing new, so I'm not sure what breakthrough is being claimed.
Light travels slower in any medium more dense than a vacuum, which has no density at all. For example, light travelling through glass slows to two-thirds its speed in a vacuum. If the glass is altered, the light can be slowed even further.

The NEC team produced the opposite effect. Inside a chamber, they changed the state of a vapour in a way that light travelling through it would travel faster than normal. When the pulse of light travelled through the vapour, the pulse reconfigured as some component waves stretched and others compressed. As the waves approached the end of the chamber, they recombined, forming the original pulse.

The key to the experiment was that the pulse reformed before it could have gotten there by simply travelling through empty space. This means that, when the waves of the light distorted, the pulse traveled forward in time.

The Problem With Pandemics

Here are a few facts to ponder about pandemics:
  • Viruses mutate, so any conventional vaccine must be delayed until the disaster is in progress.
  • Typically up to six months are required to develop a vaccine, or about the same amount of time the 1918 flu pandemic took to kill 25 million people.
  • The world's entire capacity for vaccine production could produce 400 million doses. There are 6 billion people in the world. Do the math.

While some researchers are investigating wide-spectrum vaccines, adjuvants to make the vaccines more effective, and faster production, the amount of effort does not match the threat. A pandemic is coming. It may not be this year or next, but eventually it will come, and vaccines will be too late and too few.

Beyond vaccines there are the recommendations of the Lifeboat Foundation's BioShield program, which among other things urges the development of a number of promising new technologies and strategies for fighting viruses. We need to expedite development of these now.

Greenhouse Effect A Myth?

Greenhouse effect is a myth, say scientists | the Daily Mail:
"Research said to prove that greenhouse gases cause climate change has been condemned as a sham by scientists.

A United Nations report earlier this year said humans are very likely to be to blame for global warming and there is 'virtually no doubt' it is linked to man's use of fossil fuels.

But other climate experts say there is little scientific evidence to support the theory.

In fact global warming could be caused by increased solar activity such as a massive eruption."

Global Warming vs. Nuclear Winter

New Scientist reports on a study on the effects of a "small-scale" nuclear war, with the detonation of 100 Hiroshima-sized weapons.
A regional exchange of relatively small nuclear weapons could plunge the world into a decade-long "nuclear winter", destroying agriculture and killing millions, according to a new study.

...Even taking global warming into account, the models predict that the cooling of the planet for a decade following the exchange would be nearly twice as great as the global warming of the past century, causing colder temperatures than Europe’s "Little Ice Age" of the 16th to 18th centuries.

Although this might look perversely like a welcome counter-balance to global warming, the researchers say it would cause equally devastating changes in weather patterns and rainfall. That, plus reduced sunlight, would shorten growing seasons and destroy crops worldwide, to the detriment of all.

ABC Developing "Cavemen"

Those who whine that the commercials on TV are better than the programming should be happy for this news from Variety:

Winner for most unusual piece of development this pilot season goes to ABC, which has turned a series of quirky Geico commercials into an actual half-hour comedy project.

"Cavemen" will revolve around three pre-historic men who must battle prejudice as they attempt to live as normal thirtysomethings in modern Atlanta.

Budget Delays Orion Until 2015


Space.com brings this depressing news. Well, the idea is "pay as you go" so if we don't pay, we don't go. This is bad news because with Shuttle retiring in 2010, we'll have no manned launch capacity for five years, and the way things are going in Russia it's not a given that we can buy rides from them. We may not be able to get to our own space station.
NASA Administrator Mike Griffin told a Senate panel Wednesday that development of Orion crew spacecraft and the Ares launch vehicle will be delayed four to six months, pushing the first operational flight of the new system into 2015.

Griffin said the slip is unavoidable in the face of a flat 2007 budget that denies NASA’s exploration program about half of the more than $900 million increase it was seeking [image].

“The reduction does not halt any planned work we were going to do on [Orion and Ares] but it does stretch it out,” Griffin told the Senate Commerce space and aeronautics subcommittee.

He said the slip would delay everything from the planned April 2009 test flight of the Ares I-1 rocket to the first operational flight, which had been targeted to occur no later than 2014.

“We can expect a slip into early 2015,” he said.

War Without Oil

How do we field a military that's completely dependent on oil when that resource is becoming scarce?

In his thesis "War Without Oil: A Catalyst for True Transformation", USAF Lt. Col. Michael J. Hornitschek lays out a compelling arguement and vision for a petroleum-free military by 2050. It's obvious that a military that uses 300,000 barrels of oil a day will not be sustainable much longer. What comes next? Read this and see.

International Date Line Confuses F-22 Raptors


Geez. Better keep the fleet grounded when Daylight Savings Time kicks in.
WASHINGTON (AP)- The Air Force says it's correcting technological glitches in roughly 87 F-22 Raptor fighter jets. The computer systems on six of the aircraft were disabled earlier this month during a flight from Hawaii to Japan. An Air Force colonel says the stealth fighter jets were participating in an inaugural 12-hour test flight to Kadena Air Base in Okinawa when a "navigation anomaly" occurred. The computer glitch happened as the aircraft crossed the international date line. It crippled navigation systems and hindered communications. The Air Force says one pilot was able to contact contractor Lockheed Martin to troubleshoot the error during the flight. Several pilots attempted to reboot the system with no success and returned to Hawaii with the help of aerial refueling tankers as a safety precaution. (Copyright 2007 Associated Press.)

Non-Regulation Patches

Sometimes patriotic, often profane and always funny as hell, these very politically incorrect, non-regulation patches let our troops inject a bit of black humour into the battlespace.

Among my favorites are the "Tactical Trunk Monkey" and "Team America" patches. These and many more can be found at Mil-Spec Monkey (click on "Morale"). Warning: graphic language!
